     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0027]    The foregoing and other technical characteristics of the present invention will become apparent with the detailed description of the preferred embodiments and the illustration of the related drawings. 
         [0028]    With reference to  FIG. 1  for a block diagram of a supply-demand pairing system according to the invention is depicted. In the figure, the supply-demand pairing system  100  comprises a help-seeking device  1 , a rescue device  2  and a server  3 . The help-seeking device  1  and the rescue device  2  can be electronic devices such as a mobile phone having GPS positioning and navigation functions and a PDA. The help-seeking device  1  and the rescue device  2  respectively correspond to first identification information and second identification information. First identification information and second identification information can be an IP (internet protocol) address, a media access control (MAC) address, a physical address or a phone number for identifying the identifications of the help-seeking device  1  and the rescue device  2 . The server  3  can be a remote host. The help-seeking device  1  and the rescue device  2  can be connected to the server  3  via Internet. The help-seeking device  1  comprises a positioning module  11 , an input module  12 , a processing module  13 , a transmission module  14 , a display module  15 , an image capturing module  16 , a sensing module  17  and a communication module  18 . The processing module  13  is connected to the positioning module  11 , the input module  12 , the transmission module  14 , the display module  15 , the image capturing module  16 , the sensing module  17  and the communication module  18 . The rescue device  2  includes a positioning module  21 , an input module  22 , the processing module  23 , the transmission module  24 , a display module  25  and the communication module  26 . The processing module  23  is connected to the positioning module  21 , the input module  22 , the transmission module  24 , the display module  25  and the communication module  26 . The input modules  12 ,  22  can be keypads. The display modules  15 ,  25  can be display screens. The input module  12  and the display module  15  and the input module  22  and the display module  25  can be integrated into a touch input panel respectively. The image capturing module  16  can be a lens, an image sensing component or a foregoing combination. The sensing module  17  can be a temperature sensor, a humidity sensor or an infrared sensor. The transmission modules  14 ,  24  can be a network interface for uploading data of scripts, figures or images to Internet. The communication modules  18 ,  26  can be a communication chip taken as audio or video communication. 
         [0029]    The positioning module  11  of the help-seeking device  1  can position the current location of the help-seeking device to generate first current location information. The input module  12  can provide a help-seeker to input situation information, wherein situation information can include wounds of the help-seeker, number of people seeking help and current remaining goods and materials. The processing module  13  can package first identification information, first current location information and situation information into a help-seeking message. The transmission module  14  can deliver the help-seeking message to the server  3  through a network. The positioning module  21  of the rescue device  2  can perform positioning for the rescue device  2  to generate second current location information. The processing module  23  can package second identification information and second current location information into a positioning message. The transmission module  24  can send the positioning message to the server  3 . When the server  3  receives the help-seeking message and the positioning message, the help-seeking message and the positioning message are stored and performed with a comparison task so that first current location information in the help-seeking message is compared with second current location information in the positioning message. If first current location information and second current location information are at the same location area, the server  3  executes a supply-demand pairing task to send the help-seeking message to the rescue device  2  and to send the positioning message to the help-seeking device  1  such that the help-seeking device  1  is connected to the rescue device  2  through second identification information, and the rescue device  2  is connected to the help-seeking device  1  through first identification information. Accordingly, the help-seeking device  1  is connected to the rescue device  2  to achieve communication. 
         [0030]    When the help-seeking device  1  is connected to the rescue device  2 , communication between the help-seeker and the rescuer can be achieved by inputting script messages or picture messages through the input modules  12 ,  22  respectively. These messages then are transmitted by the transmission modules  14 ,  24 . Further, audio or video communication between the help-seeker and the rescuer can be performed by respectively utilizing the communication modules  18 ,  26  so as to perform talking. The help-seeker can observe second current location information of the rescue device  2  through the display module  15  to obtain the location of the rescuers. The rescuer can search first current location information of the help-seeker device  1  through the display module  25  to further obtain orientation of the help-seeker. The display module  25  further displays situation information inputted by the help-seeker. 
         [0031]    The help-seeker also utilizes the image capturing module  16  to perform image capturing. After taking ambient condition or self-image, the processing module  13  packages image information into the help-seeking message that then is transmitted to the server  3 . The help-seeker can use the sensing module  17  to sense temperature and humidity of ambient condition or sense the body temperature to generate a sensing signal. Afterward the processing module  13  computes and processes the sensing signal to become ambient information and packages ambient information into the help-seeking message. The help-seeking message then is transmitted to the server  3  through the transmission module  14 , wherein images captured by the help-seeker or ambient information obtained by the sensing module  17  is also displayed on the display modules  15 ,  25  respectively. 
         [0032]    The help-seeker can also selectively send the help-seeking message to a specific rescue device  2 . At this time, when the server  3  receives the help-seeking message and the positioning message, first identification information is compared with second identification information. If first identification information corresponds to second identification information, the server  3  performs supply-demand pairing. 
         [0033]    With reference to  FIG. 2  for a flowchart of an emergency rescue method according to the invention is depicted. The method comprises the following steps: S 21 : utilizing a help-seeking device having first identification information and GPS positioning function to position the current location to generate first current location information and provide the help-seeker to input situation information; S 22 : packaging first identification information, first current location information and situation information into a help-seeking message and deliver the message through the help-seeking device; S 23 : providing a rescue device having second identification information and GPS positioning function to position current location to generate second current location information; S 24 : packaging second identification information and second current location information into a positioning message and delivering the message; S 25 : providing a server to receive the help-seeking message and the positioning message to determine whether or not first current location information corresponds to second current location information, and if yes, a supply-demand pairing is performed; and S 26 : respectively sending the help-seeking message to the rescue device and delivering the positioning message to the help-seeking device through the server to allow the help-seeking device and the rescue device that are paired perform communication through first identification information and second identification information. 
         [0034]    With reference to  FIG. 3A  and  FIG. 3B  for a first schematic diagram and a second schematic diagram of an emergency rescue system and its help-seeking device and emergency rescue method according to the embodiment of invention are depicted. In the embodiment, a help-seeker to be rescued can use the smart phone, the PDA or the tablet computer having GPS function to look for rescue. The help-seeker can firstly initiate the GPS function of the hand-held electronic device to perform positioning of the current location. Afterward the help-seeker can utilize input buttons to input situation information, such as the quantity of people, injured degree or remained food, as shown in  FIG. 3A . Alternatively, the help-seeker can utilize the picture taking function of the hand-held electronic device  200  to capture ambient images or self-images. In addition, the help-seeker can also turn on functions of sensing temperatures, humidity or infrared ray on the hand-held electronic device  200  to sense the exterior or self-temperature or humidity. Next, when the help-seeker presses the send button, the hand-held electronic device  200  packages the current location, situation information, image information, temperature/humidity sensing information or the foregoing combination into a help-seeking message  201  that is sent to a server  300  through networks. The server  300  also receives the positioning messages  401  uploaded by different GPS devices  400 . At this time, the server  300  compares the help-seeking message  201  with many positioning messages  401 . If the help-seeking message  201  corresponds to one of the positioning messages  401 , the server  300  would execute a supply-demand pairing task to send the positioning message  401  to the hand-held electronic device  200  of the help-seeker, and the help-seeking message  201  is sent to the corresponding GPS device  400  so that the hand-held electronic device  200  is connected to the GPS device  400  to perform communication as shown in  FIG. 3B . Accordingly, the help-seeker can be directly connected to a user taking the GPS device  400  through scripts, figures, images, audio or video manner to obtain rescue. The user having the GPS device can also obtain the orientation of the help-seeker and understand the condition of the help-seeker based upon the help-seeking message  201 . The help-seeker can check the location of the user using the GPS device through a display screen of the hand-held electronic device  200 . The hand-held electronic device  200  and the GPS device respectively have identification information such as the IP address, the MAC address, the physical address or the phone number. The hand-held electronic device  200  and the GPS device  400  simultaneously send identification while respectively uploading the help-seeking message  201  and the positioning message  401 . The server  300  compares the current location of the help-seeking message  201  with identification information of the positioning message  401 . 
         [0035]    The emergency rescue system and its help-seeking device and emergency rescue method of the invention can provide communication between the the help-seeker and the rescuer through the GPS positioning device, and the help-seeking message sent from the help-seeker is not necessarily sent to a specific rescue team only, and people passing by can also receive the help-seeking message to provide appropriate and instant supports for the help-seeker. 
         [0036]    The invention improves over the prior art and complies with patent application requirements, and thus is duly filed for patent application. While the invention has been described by device of specific embodiments, numerous modifications and variations could be made thereto by those generally skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
