     This Application claims priority of Taiwan Patent Application No. 100108680, filed on Mar. 15, 2011, the entirety of which is incorporated by reference herein. 
     BACKGROUND OF THE INVENTION 
     1 . Field of the Invention 
     The present invention relates to control methods and devices of a simple node transportation system, and in particular relates to control methods and devices of a simple node transportation system for human-machine interface. 
     2 . Description of the Related Art 
     The most common example of a simple node transportation system is a common building elevator system. In general, the transportation system includes a plurality of nodes and a vehicle. The vehicle may stop by the node to facilitate loading or unloading of people or goods. A plurality of nodes of the transportation system is usually located on a route. Except for two terminal nodes of the ends of the route, any node between the terminal nodes has two adjacent nodes. Depending on the system requirements, the vehicle may stop by the nodes which have transportation requests. Each system may comprise many transportation routes and vehicles corresponding to transportation routes, those may be controlled by a control center. 
     Take the vertical moving elevator transportation system as an example; each floor with an entrance door of the elevator is regarded as a node. The elevator transportation system may comprise one elevator shaft and an elevator, or many elevator shafts and many elevators. More than one elevator route may share a set of the nodes that the elevators stop by. For example, two elevators both stop at the first floor; one of the two elevators stops at odd floors and the top floor, and the other stops at even floors and the top floor. In another example, the floors at which the two elevators stop at are the same. 
     There are two control types of a simple node transportation system. The first type may be called as intelligent transportation system, which installs a complex control interface at each node. The user can input the target node which he wants to go, and the control center of the system dispatches a vehicle to stop by the node where the user fed input. After the vehicle carries users and/or goods, the control center of the system sends a signal to the vehicle for going to the target node. In transit, the vehicle may stop by other nodes due to other requests, but users and/or goods would only leave the vehicle at the target node. Except for an emergency interface in the vehicle, the vehicle may not be equipped with any control interface. The user only needs to input a command once at the node. Besides, the user does not need to care about the relative direction of the target node. This is why the system called intelligent transportation system. 
     The second type is more traditional, the system installs a simpler control interface in each node, and the user has to determine by himself the direction of the node to which he wants to go and inputs the direction in the control interface. The control center of the system dispatches a vehicle to stop by the node which the user has input. The user has to determine whether it goes the desired direction when vehicular door opens. After the user enters the vehicle, the user has to input the target node to which he wants to go by a complicated control interface in the vehicle. This type of transportation system requires two-stage inputs, wherein the user inputs the direction of the route at the node in the first stage, and inputs the target node in the vehicle in the second stage. 
     In practice, due to the number of nodes on the same route being usually more than the number of the vehicles, only a simple interface is installed in each node with one complicated interface installed in the vehicle, the second type is more economical than the first type. Therefore, the installation number of second type transportation system is greater than the first type actually. 
     Since the development of consumer electronic systems explores in recent years, the electronic systems have made significant progress, and prices have fallen very rapidly. Therefore, there is a need for integrating several features into the aforementioned human-machine interface of a simple node transportation system through electronic systems, such as advertisement, communication, security, monitoring, warnings, and so on.

     DETAILED DESCRIPTION OF THE INVENTION 
     Please refer to  FIG. 1 .  FIG. 1  is a diagram illustrating a simple node transportation system  100  according to an embodiment of the invention. The transportation system  100  comprises two routes  120  and  140 , and two vehicles  122  and  142 . The vehicle  122  travels on the route  120 , and the other vehicle  142  travels on the route  140 . These two routes  120  and  140  may stop by a plurality of nodes  160 , which include two terminal nodes  160   a  and  160   b  . As shown, the vehicle  142  stops by the terminal node  160   a , and the vehicle  122  stops by the node  160 . 
     In an example, the sets of the nodes  160  which the two routes  120  and  140  stop by are the same. In another embodiment, the sets of the nodes  160  which the two routes  120  and  140  stop by are different, but at least share one common node  160 . 
     Each node  160  is equipped with a node controller  162  as a human-machine interaction interface. The terminal nodes  160   a  and  160   b  are equipped with the terminal node controllers  162   a  and  162   b  . The vehicles  122  and  142  are equipped with a respective vehicle controller  124  and  144  as a human-machine interaction interface. The node controller  162  and the vehicle controllers  124  and  144  are connected to a control device  110 . The control device  110  controls the vehicle controllers  124  and  144  according to the instructions received from the human-machine interface; and the control device  110  demands the vehicle controllers  124  and  144  to travel between the nodes  160  on the route and stop by the nodes  160  to load and unload people and goods. The nodes  160  and the vehicles  122  and  142  may be equipped with security doors (not shown), the control device  110  may also control the security doors for opening/closing. 
     Please refer to  FIG. 2 .  FIG. 2  is a diagram illustrating a node controller  162  according to an embodiment of the invention. The node controller  162  comprises a traditional touch module  210 , an input module  220 , an output module  230 , and a node control module  240 . 
     The traditional touch module  210  comprises a panel and the buttons with the direction indicator lights  212 , and  214 . The operation mode of the traditional touch module  210  is similar to the second type described in the description of the related art. The user first determines which direction of the target node he wants to go toward, and presses the button with the direction indicator light  212  or  214  corresponding to the direction, and then the button with the direction indicator light  212  or  214  lights up. After the vehicle arrives at the target node and opens the security doors, the button with the direction indicator light  212 , or  214  goes off. User keeps pressing the button on the direction indicator light  212  or  214  to make the security doors of the vehicle keep open. 
     The input module  220  and the output module  230  are connected to the node control module  240 . The input module  220  may comprise a mounting assembly  222  to attach the input module  220  to a proper location. The mounting assembly  222  may comprise a control mechanical equipment such that the whole input module  220  could be pitched and/or rotated in one-dimensional or multi-dimensional degrees of freedom. The input module  220  may comprises one or more of sound reception module  224  to receive monaural or multi-channel stereophonic sound. When the received volume is larger than a threshold value, the sound reception module  224  may send a signal to activate the whole or a part of the node controller  162 . If the sound reception module  224  does not receive sound over a certain volume within a certain time period, the whole or a part of the node controller  162  may switch to energy-saving mode that may save more electricity. 
     The input module  220  may comprises one or more of depth detection modules  226  to detect distance of presented object in front of the input module  220 . The depth detection module  226  may be implemented in various manners including photographic lens that has multiple overlapping angles of vision, a laser rangefinder, an ultrasonic distance measurement device and so on. The present invention does not limit implementation choices of the depth detection module  226 , as long as the implementation is capable to identify the distance between the object and the input module  220 . As shown in  FIG. 19 ,  FIG. 19  is a schematic diagram illustrating an embodiment of the depth detection module detecting a depth signal of the user in the target area of the disclosure. 
     The input module  220  may comprise a photographic module  227  and a lighting module  228 , wherein the lighting module  228  may emit the wavelength of visible light and the wavelength of infrared ray to illuminate the target area. The photographic module  227  may photograph the images in the wavelength of visible light and of infrared ray. Because there may be many complicated lighting situation for the target area photographed by the photographic module  227 , the multi-spectral photography may filter out the noise to get clearer images. The photographic module  227  may also have capability for zooming out or zooming in. The input module  220  further may comprise a motion detection module  229 . When object goes into or through the target area, the motion detection module  229  may send a signal to activate all or a part of the whole input module  220  or the node controller  162  to start via the node control module  240 . However, if no object goes into or through the target area within a certain period of time, all or a part of the node controller  162  may switch to the energy-saving mode that may save more electricity. 
     The depth detection module  226  may delimit the interesting distance between the target area and the input module  220 . In an embodiment, if the target area is an open area in front of the input module  220 , there may be many people walking around in the target area. If the input module  220  only uses the photographic module  227  and/or the motion detection module  229 , the target area may be too large. Therefore, the depth detection module  226  may be configured to restrain the depth of the target area to avoid the misjudgment resulting from the object moving behind the target area. 
     The node control module  240  is configured to receive the signal input from each module in the input module  220 , and further may process and output the signal. The part of signal processing may comprise at least three levels. The first level may comprise signal sampling, compression, format conversion, storage, and re-output. For example, the sound reception module  224  outputs the signal to the node control module  240 , and the node control module  240  may perform sampling, compression, format conversion, storage, and re-output of the audio signal. The photographic module  227  outputs the signal to the node control module  240 , and the node control module  240  may perform sampling, compression, format conversion, storage, and re-output of the video signal. The depth detection module  226  outputs the signal to the node control module  240 , and the node control module  240  may perform sampling, compression, format conversion, storage, and re-output of the depth signal. 
     The second level is the node control module  240  performing data fusion or integration between different media or related processing. For example, the node control module  240  laps the video signal over the depth signal or performs the related processing, and outputs a three-dimensional video signal. In addition, the node control module  240  may integrate the video signal with the depth signal or performs the related processing, and outputs a three-dimensional video signal animation. 
     The third level of the signal processing involves the recognition of the media content; especially when the node control module  240  uses the data fusion or integration of two or more media or related processing to recognize people and gesture in the target area. When the signal output from the photographic module  227  and/or the signal output from the depth detection module  226  are integrated into the output signal, the node control module  240  at least can perform face recognition and gesture recognition for people. Face recognition comprises at least position recognizing art and characteristic recognizing art. The characteristic recognizing art used to recognize the gender, the identity or the approximate age of the user through the characteristics of faces is more sophisticated than the position recognizing art used to recognize the positions where faces are. In additional to recognizing so-called hard point such as the center of a palm and/or finger tips, the recognition may include the vertices of the face, elbows, shoulders, neck, hips, knees and other vertices. The lines between corresponding vertices and recognized human parts form a skeleton of a human body. With the change of the time axis, the node control module  240  may recognize the movements of the human body, such as raising hands, waving hands, shaking hands and so on. According to the node control module  240  in this embodiment of the invention, the node control module  240  may perform the three levels of the signal processing. 
     The output module  230  comprises a display  231  and more than one speaker  232 . The display  231  may show separate windows, which comprise a first target area window  234  configured to display the situation of the target area corresponding to the node controller  162 . 
     Next, please refer to the  FIG. 3 , which is a flowchart of a user control method  300  according to an embodiment of the invention. The user may control the node controller  162  installed in the node  160  according the method  300 , as shown in  FIG. 13A . In step  310 , the node control module  240  may detect that one or many users have entered the target area where the node controller  162  is located by the sound reception module  224 , the motion detection module  229  and/or the photographic module  227 . Next, in an optional step  320 , the node control module  240  may adjust the lighting module  228  for lighting the target area to make the photographic module  227  photograph the illuminated target area clearly. The node control module  240  may also adjust the direction of the mounting assembly  222  to make the photographic module  227  focus on the user in the target area clearly. 
     In step  330 , the node control module  240  sends the image photographed by the photographic module  227  to the first target area window  234  of the display  231 . Furthermore, the node control module  240  may also remind the user that he has entered the target area where the node controller  162  is located by the speaker  232 . In an embodiment, the node control module  240  may recognize the characteristics of the user and mark the characteristics according to the three levels of the signal processing. The manners of marking the characteristics may comprise but not be limited to the following manners: framing the human face; displaying the user&#39;s ID or name if the node control module  240  has recognized the identity of the user; and/or verbally greeting the user by user&#39;s ID or name. For example, the node control module  240  produces a voice of “someone, hello, may I ask you to go upstairs or downstairs?” through the speaker  232 ; marks the control hard points like the palm of hands /fists /fingers and so on; and marks the vertices of each joint of the human body and the lines between corresponding vertices. 
     Next, in step  340 , the node control module  240  detects the first gesture of the user to start the control process of the transportation system. The first gesture mentioned in the invention may comprise a static gesture, such as raising the right hand in  FIG. 16 , and may also comprise a dynamic action, such as waving the right palm, holding or opening a fist, and may also comprise static gestures and dynamic actions, such as raising the right hand and doing the pose of holding or opening the fist. In step  330 , the node control module  240  may also prompt the user to do the first gesture by the sound or the image, and makes the user that uses the node controller  162  at the first time or are not familiar with the operation of the node controller  162  operate smoothly. In one embodiment, the first gesture may comprise plural kinds of gestures and/or actions, such as raising the right hand or waving the right palm in  FIG. 17 . As long as the user does one of the gestures, the node control module  240  regards the gesture as the first gesture. Similarly, after detecting that the user does the first gesture, the node control module  240  may frame the user specially, make a sound to confirm that the user has inputted the first gesture, and guide the user to do the second gesture. 
     In an embodiment, the second gesture may comprise the plural kinds of gestures and/or actions. For example, the gesture of turning the palm up and the gesture of turning the palm down would correspond to the two directions of the movement of the vehicle respectively. In another embodiment, the second gesture may comprise the positions in which the control hard points of the user are showed in the display  231 . For example, the user moves the control hard points to the direction control area  233  in the display  231  within a period of time or does the gesture of clenching the fist/finger splay. In step  350 , the node control module  240  detects the second gesture of the user to arrange for the vehicle. The effect is like pressing the button with the direction indicator light  212 , or  214  of the traditional touch module  210 , wherein the operation mode is the second type described in accordance with the prior art. 
     Finally, in step  360 , the node control module  240  may turn on the light corresponding to the direction in the direction control area  233  of the display  231 , and may also make a sound to confirm the direction, and may turn on the button with the direction indicator light  212 , or  214  corresponding to the direction in the traditional touch module  210 , as shown in  FIG. 14 . 
     In a similar example, if the user wants to cancel the previous instructions, the node control module  240  may detect the third gesture of the user, and then turn off the light corresponding to the direction light in the direction control area  233  of the display  231 , and also make a sound to confirm the direction, and turn off the button with the direction indicator light  212 , or  214  corresponding to the direction in the traditional touch module  210 . 
     In another embodiment, many users can operate the node controller  162  simultaneously. For example, the first user and the second user may operate the operation of inputting two directions simultaneously, as long as the target area may accommodate many users, and the node controller  162  may analyze the gestures and actions. In other words, the input method  300  used by two or more users may be used in different steps. For example, when the input method  300  used by the first user stays in step  330 , the input method  300  used by the second user may proceed as in the step  350 . 
     Back to  FIG. 2 , in many windows of the display  231 , in addition to the direction control area  233  and the first area window  234  introduced before, the display  231  may comprise a second target area window  236 , an advertisement area window  238  and an emergency notification area window  239 . The second target area window  236  is configured to display the node which the vehicle stops by, and the situation of the target area of the node. In  FIG. 1 , for example, assume that the movement direction of the vehicle  122  is downward, and the movement direction of the vehicle  142  is upward. In any node  160  or  160   b , after the user inputs the instruction that the direction is upward, the second target area windows  236  of these node controllers  162  display information that the node that the vehicle  142  stopped by is  160   a  and the audio and video recorded by the input module  220  of the node controller  162   a  . When the vehicle  142  does not appear, the user in each node can monitor the current situations of the vehicle  142  through the second target area window  236 . 
     The advertisement area window  238  may broadcast the wireless television programs, the programs stored in advance, a temporary scrolling text marquee advertisement and so on. Furthermore, the advertisement area window  238  may interact with the user by playing the simple gesture game. For example, stretching exercises, throwing or catching a ball, dancing and so on. As long as the user does not use the first and second gestures of the transportation system in the game, the node controller  162  may even allow the user to play the game and operate the control method of the transportation systems at the same time. 
     Finally, the emergency notification area window  239  is configured to allow the user to start the emergency notification area window  239  through an emergency gesture when the user encounters an emergency. The emergency gesture may be a “full time” gesture. It means that no matter when it is, as long as the node control module  240  detects that any person in the target area does this emergency gesture, then the node control module  240  enters the situation of the emergency notification. In another embodiment, as long as the node control module  240  detects that the hard points of the user have moved into the emergency notification area  239  and the emergency gesture is formed by the hard points, the node control module  240  would enter the situation of the emergency notification. After the node control module  240  enters the situation of the emergency notification, the user can talk to the handler who deals with the emergency through the sound reception module  224  of the input module  220 , the photographic module  227  and the output module  230 . In the situation of the emergency notification, the node control module  240  records and stores the audio, video, and even the depth of the signal for retrieving the records in the aftermath. 
     It is noted that, although  FIG. 3  shows that the control method  300  includes step  340  and step  350 , wherein step  340  and step  350  detect the first gesture and the second gesture of the user respectively, the reason of detecting the first and the second gesture is to reduce the probability of the misjudgment. In another embodiment of the invention, after detecting directly the second gesture of the user, the node control module  240  may arrange for the vehicle immediately. 
     Please refer to  FIG. 4 , which shows a diagram illustrating a vehicle controller  124  according to an embodiment of the invention. The vehicle controller  124  or  144  comprises four modules, which are a traditional touch module  410 , an input module  220 , an output module  230  and a vehicle control module  440 , respectively. The input module  220  and the output module  230  are connected to the vehicle control module  440  respectively. 
     The traditional touch module  410  comprises a panel and a plurality of buttons with the direction indicator lights. In this example, a plurality of nodes represent the first floor to the sixth floor respectively, and therefore 1F˜6F represent the first floor to the sixth floor. The operation mode of the traditional touch module  410  is similar to the second type described in the description of the related art, the user first determines which direction of the target node he wants to go toward, and presses the button with the direction indicator light corresponding to the direction, and then the button with the direction indicator light lights up. 
     The input module  220  of the vehicle controller  124  and the input module  220  of the node controller  162  are the same basically, so the input module  220  is not mentioned here. The output module  230  of the vehicle controller  124  and the output module  230  of the node controller  162  are the same basically. The different part is that the direction control area  233  of the display  231  is changed to a node indicating area  432 . The node indicating area  432  displays the node corresponding to the traditional touch module  410 . In the above example, the node indicating area  432  shows that six nodes represent the first to the sixth floor respectively. 
     Please refer to  FIG. 5 , which shows a diagram illustrating a user control method  500  according to an embodiment of the invention. The user may control the vehicle controller  124  installed in the vehicle  122  according the method  500 , as shown in  FIG. 13B . The control method  500  is quite similar to the control method  300 , and for most of the control method  500  may be referenced to the steps of the control method  300 . In step  510 , the vehicle control module  440  may detect that one or many users have entered the vehicle by the sound reception module  224 , the motion detection module  229  and/or the photographic module  227 . Next, in an optional step  520 , the vehicle control module  440  may adjust the lighting module  228  for lighting the target area to make the photographic module  227  photograph the illuminated target area clearly. The vehicle control module  440  may also adjust the direction of the mounting assembly  222  to make the photographic module  227  focus on the users in the target area clearly. 
     In step  530 , the vehicle control module  440  sends the image photographed by the photographic module  227  to the first target area window  234  of the display  231 . Furthermore, the vehicle control module  440  may also remind the user that he has entered the vehicle through the speaker  232  and let the user determine whether he needs to control the vehicle or not. In an embodiment, the vehicle control module  440  may recognize the characteristics and mark the characteristics according to the three levels of the signal processing. The manners of marking the characteristics may comprise but are not be limited to the following several manners: framing the human face; displaying the user&#39;s ID or name if the node control module  240  has recognized the identity of the user, and/or verbally greeting to the user&#39;s ID or name. For example, the node control module  240  makes a sound of “someone, hello, which floor are you going to?”; marks the control hard points like the palm of hands/fist /fingers and so on; and marks the vertices of each joint of the human body and the lines between corresponding vertices. 
     Next, in step  540 , the vehicle control module  440  detects the third gesture of the user to start the control process of the transportation system. In the step  530 , the vehicle control module  440  may also prompt the user to do the third gesture by the sound or image. Similarly, after detecting that the user does the third gesture, the vehicle control module  440  may frame the user specially, make a sound to confirm that the user has entered the third gesture, and guide the user to do the fourth gesture. In an embodiment, the third gesture and the first gesture may be the same. 
     In an embodiment, the fourth gesture may comprise the plural kinds of gestures and/or actions. For example, the display  231  displays the route and the plurality of nodes. The user turns the palm left and turns the palm right corresponding to two directions of the movement of the vehicle, and the vehicle control module  440  may use the control hard points of the palm to choose the direction in which the user wants to go. In another embodiment, the fourth gesture may comprise the control hard points of the user in the position in the display  231 . For example, the user moves the control hard points to the node indicating area  432  in the display  231  within a period of time or does the gesture of clenching the fists/finger splay, and may use the control hard points of the palm to choose the direction in which the user wants to go. In step  550 , the vehicle control module  440  detects the fourth gesture of the user to arrange for the vehicle. The effect is like pressing the buttons with the direction indicator lights of the traditional touch module  410 , and the operation mode is the second type described in accordance with the prior art. 
     Finally, in step  560 , the vehicle control module  440  may turn on the light of the target node in the node indicating area  432 , may also make a sound to confirm, and may turn on the corresponding button with the direction indicator light in the traditional touch module  410 , as shown in  FIG. 15 . 
     In a similar example, if the user wants to cancel the previous instructions, the vehicle control module  440  may detect the third gesture of the user, and then turn off the light corresponding to the target node in the node indicating area  432  of the display  231 , and also make a sound to confirm, and turn off the corresponding buttons with the direction indicator lights in the traditional touch module  410 . 
     It is noted that, although  FIG. 5  shows that the control method  500  includes step  540  and step  550 , wherein step  540  and step  550  detect the third gesture and the fourth gesture of the user respectively, the reason of detecting the first and the second gesture is to reduce the probability of the misjudgments. In another embodiment of the invention, after detecting directly the fourth gesture of the user, the vehicle control module  440  may arrange for the vehicle immediately. 
     In another embodiment, many users can operate the vehicle controller  124  simultaneously. For example, the first user and the second user operate the operation of inputting two directions simultaneously in  FIG. 18 , as long as the target area may accommodate many users, and the vehicle controller  124  may analyze the gestures and actions. In other words, the input method  500  used by two or more users may be in different steps. For example, when the input method  500  used by the first user stays in step  530 , the input method  500  used by the second user may proceed to the step  550 . 
     In many cases, the user attempts to enter or exit the vehicle while the security doors are closing. In general, although the security doors may be equipped with the security measures to avoid jamming people or goods, taking multiple security measures for the vehicle is still needed to keep safer. According to an embodiment of the invention, the vehicle controller  124  and the node controller  162  may set a prohibited area within a certain range from the security doors. When the security doors is closing, the photographic module  227  and/or the depth detection module  226  of the input module  220  detect that the object is in the prohibited area, and the vehicle controller  124  and the node controller  162  may open the security doors, and may also send a signal to the display  231  and the speaker  232  to issue a warning. 
     Although many simple node transportation systems exist in the world, the control part of the simple node transportation systems still belongs to the traditional type. According to an embodiment of the invention, minimal modification of the original simple node transportation system can be achieved. Please refer to  FIG. 6 , which shows a diagram illustrating each component connected in a simple node transportation system  600  according to an embodiment of the invention. 
     The transportation system  600  comprises a control device  110 . The control device  100  further comprises a traditional control module  610  and an intelligent control module  620 . The traditional control module  610  is configured to the traditional touch module  410  of the vehicle controller  124  and the traditional touch module  210  of the node controller  162 . The traditional control module  610  receives the input from the user of two traditional touch modules  210  and  410 , and may control the scheduling and the running of the vehicle. The traditional control module  610  may be configured to connect to a traditional network control center  640  to transmit the running situation of the transportation system  600  to the traditional network control center  640 . 
     In this embodiment, the intelligent control module  620  is configured to the vehicle control module  440  of the vehicle controller  124  and the node control module  240  of the node controller  162 . In an example, the connected-state may present a shape of a star, and the intelligent control module  620  is the center of the star, such that each vehicle control module  440  and each node control module  240  are connected to each other through the intelligent control module  620 . In another example, each component is connected to each other through a bus or the Internet. No matter what the connections, each vehicle control module  440  and each node control module  240  may transmit the signals to each other, and the intelligent control module  620  may be also connected to each vehicle control module  440  and each node control module  240 . The intelligent control module  620  may also be connected to an intelligent network control center  630  to receive the control signal of the intelligent network control center  630 . 
     In this embodiment, the traditional touch module  210  of the node controller  162  and the node control module  240  are connected to each other. After receiving the input from the user, the node control module  240  gives the instruction to the corresponding direction of the traditional touch module  210  through the connecting circuit. After the traditional touch module  210  receives the instruction sent from the node control module  240 , for example, the button of “up stairs” and “down stairs”, the traditional touch module  210  follows the steps to inform the traditional control module  610 , and then the traditional control module  610  plans a schedule for the vehicle. If the user gives the instruction to the button with the direction indicator light  212 , or  214  of the traditional touch module  210 , the node control module  240  also receives a signal indicating what instruction was given by the user through the connecting circuit, and further turns on the light corresponding to the direction of the direction control area  233  in the display  231 . If the user cancels the instruction to the traditional touch module  210 , the node control module  240  also receives a signal indicating what instruction was cancelled by the user through the connecting circuit, and further turns off the light corresponding to the direction of the direction control area  233  in the display  231 . 
     When the vehicle arranged by the traditional control module  610  arrives at the node  160 , the traditional control module  610  turns off the button with the direction indicator light  212 , or  214  of the traditional touch module  210 . When receiving the signal indicating that the button with the direction indicator light  212 , or  214  is turned off through the connecting circuit, the node control module  240  may receive the signal indicating that the vehicle has arrived at the node  160 . Therefore, the node control module  240  may turn off the light corresponding to the direction within the direction control area  233  of the display  231 , and also inform the intelligent control module  620  that the vehicle has arrived at the node  160 . The intelligent control module  620  may inform the node control module  240  of another node  160 , and send a signal to the second target  236  of the display  231  to display the video signal of the input module  210  of the node which the vehicle stops by. The intelligent control module  620  may also inform the vehicle control module  440 , and send a signal to the second target  236  of the display  231  to display the video signal of the input module  210  of the node which the vehicle stops by. The intelligent control module  620  further may inform the intelligent network control center  630  to monitor the signal of the vehicle and the input module  210  of the node which the vehicle stops by. 
     Similarly, in this embodiment, the traditional touch module  410  and the vehicle control module  440  of the vehicle controller  124  are connected to each other. After receiving the input from the user, the vehicle control module  440  gives the instruction to the node corresponding to the traditional touch module  410  by the connecting circuit. After the traditional touch module  410  receives the instruction from the vehicle control module  440 , for example, after pressing the button of “the first floor”, the traditional touch module  410  follows the steps to inform the traditional control module  610 , and then the traditional control module  610  plans a schedule for the vehicle. If the user gives the instruction to the traditional touch module  410 , the vehicle control module  440  also receives a signal indicating what instruction was given by the user through the connecting circuit, and further turns on the light corresponding to the node of the node instruction area  432  in the display  231 . If the user cancels the instruction to the traditional touch module  410 , the vehicle control module  440  also receives a signal indicating what instruction was cancelled by the user through the connecting circuit, and further turns off the light corresponding to the node of the direction control area  432  in the display  231 . 
     When the vehicle arranged by the traditional control module  610  arrives at a certain node  160 , the traditional control module  610  turns off the light of the node of the traditional touch module  410 . When receiving the signal indicating the light of the node is turned off by the connecting circuit, the vehicle control module  440  may receive the signal indicating that the vehicle has arrived at the node  160 . Therefore, the vehicle control module  440  may turn off the light corresponding to the direction of the node instruction area  432  in the display  231 , and also inform the intelligent control module  620  that the vehicle has arrived at the node  160 . 
     Because the simple node transportation system  600  may affect the safety of the passengers, the traditional control module  610  has to be authenticated and testes repeatedly. The advantage showed by an embodiment of  FIG. 6  is that the new components do not need to be changed or be connected directly to the traditional control module  610 . The traditional control module  610  does not have to authenticate and test the security function of the core again. However, the con is that the integration level may be lower and the system reaction may be slower. If the simple node transportation system  600  needs a higher degree of integration functions and faster reaction velocity, the simple node transportation system  600  may use the following mode of the connection. 
     In addition, in the embodiment of  FIG. 6 , the simple node transportation system  600  does not install the intelligent control module  620 . In an example, as a result of the passengers discharging at some certain nodes  160  being larger, the node controller  162  are merely needed to attach to some nodes  160  for performing the control function by the gestures. In another example, only the vehicle controller  124  may be installed in the simple node transportation system  600 . In other words, the vehicle controller  124 , the node controller  162 , and the intelligent control module  620  may exist alone, or cooperate with each other. 
     Please refer to  FIG. 7 , which shows a diagram illustrating each component connected in a simple node transportation system  700  according to an embodiment of the invention. The main difference between the embodiment of  FIG. 7  and  FIG. 6  is that the traditional control module  610  of the transportation system  700  and the intelligent control module  620  are connected to each other, while the transportation system  600  is connected to the vehicle and the node. In this embodiment, the traditional control module  610  may output and input the position of the vehicle and the signal indicating that the situation that the users issue instructions in each node. Therefore, the intelligent control module  620  may transmit the information transmitted from the traditional control module  610  to each vehicle controller  124  and each node controller  162 , so that the vehicle control module  440  and the node control module  240  corresponding to each vehicle controller  124  and each node controller  162  may be displayed in the node instruction area  432  and the direction control area  233  of the display  231  correctly. The intelligent control module  620  may also transmit the instruction to the traditional control module  610  to arrange for the vehicle according to the input of each vehicle controller  124  and each node controller  162 . 
     It is noted that, in the embodiment of the simple node transportation system  700 , the intelligent control module  620  has to be there, but not every vehicle and node have to be installed the vehicle controller  124  and the node controller  162 . In addition, the touch module  410  of the traditional vehicle controller  124  and the vehicle control module  440  may also be connected to each other. The traditional touch module  210  of the node controller  162  and the node control module  240  may also be connected to each other. 
     The simple node transportation system  700  may also comprises a network control center  710 , which is connected to the traditional control module  610  and the intelligent control module  620 . The network control center  710  may monitor the vehicle and the signal of the input module  210  of the node which the vehicle stops by. 
     The parts described above all improve the controlling mode of the second form described in the prior art, and the following parts modify the intelligent controlling mode of the first form described in the prior art. The control method of the first form is that the user can input the node  160  which the user wants to go to at the node  160  in advance. After entering the vehicle, the user does not input the node  160  which the user wants to go to. 
     Please refer to  FIG. 8 , which shows a diagram illustrating a node controller  162  according to an embodiment of the invention. The node controller  162  of the embodiment is actually very similar to the vehicle controller  124  showed in  FIG. 4 . The user can choose the node  160  which the user wants to go to through the traditional touch module  410 , and also can choose the node  160  which the user wants to go to through the input module  220  and the output module  230  controlled by a intelligent node control module  840 . After seeing the previous introduction, a person of ordinary skill should be able to understand the operation mode, and therefore the operation mode is not detailed here. 
     In the regulation of teaching in some religion, the users which are a different gender can not take the same vehicle. To avoid the problem of sexual harassment between different genders, in an embodiment of the invention, the intelligent node control module  840  may recognize the gender of the user, and further inform the control device  110 . Therefore, the control device  110  may arrange for a vehicle to stop by the node  160  appropriately. In another embodiment of the invention, if the genders of the group of the users are different, the intelligent node control module  840  may inform the vehicle that is coming or has stopped by the node  160  contains which gender. If the user of the other gender wants to enter the vehicle, the intelligent node control module  840  may issue a warning and/or notify the remote administrator. 
     Please refer to  FIG. 9 , which shows a diagram illustrating a vehicle controller  124  according to an embodiment of the invention. In the transportation system of the first form, after entering the vehicle, the user does not have to input the node  160  which he wants to go to again, so the vehicle controller  124  is not equipped with the traditional touch module. The vehicle controller  124  of the embodiment is actually very similar to the vehicle controller  124  in  FIG. 4 . The vehicle control module  940  is also very similar to the vehicle control module  440 . The difference is that the vehicle control module  940  does not have to be connected to the traditional touch module  410 . After seeing the previous introduction, a person of ordinary skill should be able to understand the operation mode, and therefore the operation mode is not detailed here. 
     Similarly, if the vehicle has been set for a specific gender, the vehicle control module  940  detects that the user of the other gender has entered the vehicle, and the vehicle control module  940  may issue a warning and/or notify the remote administrator. 
     Please refer to  FIG. 10 , which shows a diagram illustrating each component connected in a simple node transportation system  1000  according to an embodiment of the invention.  FIG. 10  is similar to  FIG. 6 , wherein the intelligent node control module  840  and the traditional touch module  410  are connected to each other, and there is no traditional touch module in the vehicle. 
     Please refer to  FIG. 11 , which shows a diagram illustrating each component connected in a simple node transportation system  1100  according to an embodiment of the invention.  FIG. 11  is similar to  FIG. 7 , wherein the traditional control module  610  of the transportation system  1100  and the intelligent control module  620  are connected to each other. 
     In an embodiment of the invention, the traditional control module  610  and the intelligent control module  620  supply power respectively. In another embodiment, the power of the traditional touch module  210  and  410  and the traditional control module  610  belong to the same system. In addition to the traditional touch module  210  and  410 , the power of each vehicle controller  124  and each node controller  162  and the intelligent control module  620  belong to the same system. Though, these two power systems may be equipped with the uninterruptible power supply device, only one of them has a problem, and the problem does not affect other components of the power system. 
     Please refer to  FIG. 12 , which shows a diagram illustrating an intelligent control module  620  according to an embodiment of the invention. The intelligent control module  620  may comprise a network module  1210  configured to be connected to each vehicle controller  124  and each node controller  162 . In an embodiment, the network module  1210  may be connected to an intelligent network control center  630 , the network control center  710  and/or the traditional control module  610 . 
     The intelligent control module  620  may comprise an advertisement module  1220  configured to store various advertisement videos, or receive the signal from other radio broadcast stations for supplying each vehicle controller  124  and each node controller  162  to broadcast in the advertisement area  238  in the display  231 . Because each vehicle controller  124  and each node controller  124  may return the image of the user, in an embodiment, the advertisement module  1220  may provide the individual differentiated advertisements according to the user photographed by each vehicle controller  124  and each node controller  162 . For example, if the user photographed by a certain node controller  162  is a woman, the advertisement module  1220  may send a signal to the node controller  162  to broadcast the advertisements about cosmetics or costume. If the user photographed by a certain node controller  162  is a man, the advertisement module  1220  may send a signal to the node controller  162  to broadcast the advertisements about cameras or computers. 
     The intelligent control module  620  may comprises a record module  1230  configured to store various signals recorded by each vehicle controller  124  and each node controller  162 , wherein the signals include video signals, audio signals and depth signals. The record module  1230  may determine whether the record module  1230  records the signals or not according to the signals transmitted from the motion detection module  229  of the input module  220 . If the motion detection module  229  does not detect any movement, the record module  1230  may not have to record the signal of the vehicle and the node. 
     The intelligent control module  620  may comprises an switch module  1240  configured to exchange the information with the traditional control module  610 . In the embodiment shown in  FIG. 7  and  FIG. 11 , the intelligent control module  620  may exchange the information with the traditional control module  610 , and the switch module  1240  is configured to provide the interpretation for transforming signals. In addition, the switch module  1240  may also be configured to connect to any vehicle/node and the intelligent network control center  630 /the network control center  710  to let the remote administrator in the intelligent network control center  630 /the network control center  710  communicate with the user in the vehicle/node directly. 
     In conclusion, in addition to the advantages mentioned above, the present invention may also provide at least the following advantages. First, the user does not need to touch any button, and the user can control the simple node transportation system. For example, in health sensitive environments or in hospitals or laboratories needing high infection control, the user can avoid the contact of infection. Furthermore, the simple node transportation system may be inputted with instructions by many users at the same time according to the invention, and does not force the users to squeeze before the conventional touch panel. Especially in a narrow vehicle, the user only lifts a finger, and the user can operate the vehicle. Moreover, the invention may enhance the rate of the attention of the advertisement. The user needs to peer at the display to control the simple node transportation system, and therefore the advertisement in the display may gain higher rate of the attention. If the advertisement is integrated with segment advertisements which may be classified according the passengers, the effect is better than other advertisement machines. Furthermore, the user can see the running situations of the vehicle through the second target area. For example, the current situations of the users pass in and out the vehicle that stops by the node, or the interior situations of the vehicle. The disclosure may provide a better system to know the situations, and avoid users from waiting for the vehicle in the case where they do not know what happened. Finally, the invention may enhance the safety of the system. For example, the setting of the prohibited area may add a layer of insurance on the switches of the security doors, or for example, the system may record the signal at any time and send it to the remote for storing the signal, so that the remote manager can communicate with the user in the node target areas. The above-mentioned examples may enhance the safety of the simple node transportation system.
