     FIELD OF THE DISCLOSURE 
       [0002]    The present disclosure relates to a remote management system of a construction machinery, and more particularly, to a method for setting a transmission cycle of information of a construction machinery for enabling a user or a provider to directly set the transmission cycle of the information of the construction machinery transmitted from a communication terminal connected with the construction machinery to a control server. 
       BACKGROUND OF THE DISCLOSURE 
       [0003]    In general, in a remote management system of a construction machinery, a communication terminal connected with a vehicle control device of a construction machinery such as an excavator, a wheel loader, or the like transmits to a control server by using a mobile communication network or a satellite communication network information including engine rpm (radius per minute), battery voltage, the temperature of cooling water, the temperature of oil, on/off sensing information of various switches, on/off sensing information of solenoids or relays, error information (error code), an operation time for each operation mode, an engine operation time, a filter/oil using time, the pressures of a pump and a cylinder, fuel information, load rate information, positional information, and the like of the machinery. 
         [0004]    The communication terminal transmits the information of the construction machinery to the control server at a predetermined transmission cycle and in general, a provider that provides the remote management system previously estimates a monthly communication cost of a level suitable for a customer and determines optimal values of a monthly transmission data amount or the number of monthly transmission times for each communication type according to the estimated monthly communication cost. Further, the transmission cycle in the communication terminal is determined for each data packet without departing from the optimal values and this is set as a default. For example, a default value is set so that a data packet containing monitoring information, packet A, is transmitted once a day and a data packet containing positional information, packet B, is transmitted four times a day. 
         [0005]    As described above, at present, the provider previously estimates the monthly communication cost of the level suitable for the customer and information data is transmitted only at the transmission cycle set as the default to suit the optimal values of the monthly transmission data amount or the number of monthly transmission times for each communication type according to the estimated monthly communication cost. 
         [0006]    As a result, even though a customer who estimates a cost lower than the communication cost estimated by the provider wants to further increase the transmission cycle, the customer cannot additionally adjust the set transmission cycle at present. 
         [0007]    Further, even though the customer wants to change a cycle value for necessary information among information as necessary, the customer cannot additionally adjust the cycle value, and as a result, the customer cannot change a predetermined cycle value. 
         [0008]    The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.

     DETAILED DESCRIPTION 
       [0026]    Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that the same components refer to the same reference numerals anywhere as possible in the drawings. In the following description, specific detailed matters will be described and are provided to the more overall understanding of the present disclosure. Further, in describing the present disclosure, well-known functions or constructions will not be described in detail since they may unnecessarily obscure the understanding of the present disclosure. 
         [0027]    First, an internal configuration of a remote management system of a construction machinery according to an exemplary embodiment of the present disclosure will be described with reference to  FIG. 1 . 
         [0028]    Referring to  FIG. 1 , the remote management system of the construction machinery includes a communication terminal  110  connected with the construction machinery and a control server  150  remotely managing information of construction machineries, and includes a user terminal  160  used for a user or a provider to set a transmission cycle of the information of the construction machinery by accessing the control server  150  through the Internet. At this time, the communication terminal  110  communicates with the control server  150  through a mobile communication network  140  or a satellite communication network  130 . 
         [0029]    First, the user terminal  160  as a terminal for communicating with the control server  150  allows a customer or a provider which is an owner of the construction machinery to access the Web of the control server  150  through an Interne network  162  by using the user terminal  160  and directly set the desired transmission cycle of the information of the construction machinery. As the user terminal  160 , all terminals that can access the Internet network, such as a personal computer (PC), a mobile terminal, a PDA, and the like may be used. As another exemplary embodiment, the user may directly set the information transmission cycle of the construction machinery through an input device (not shown) of the construction machinery  100 . 
         [0030]    An internal configuration of the control server  150  will be described below. The control server  150  includes a transmission/reception unit  154 , a memory unit  158 , and a control unit  152 . 
         [0031]    First, the transmission/reception unit  154  as a unit for transmitting/receiving data through the satellite communication network  130  or the mobile communication network  140  is shown as a unit having both transmission and reception functions in the present disclosure, but may separately include a transmitter and a receiver. 
         [0032]    The memory unit  158  stores the information of the construction machinery  100 . The memory unit  158  stores an initially set transmission cycle value for each information data packet. Further, at this time, the information data packet may be classified into a first data packet containing monitoring information, a second data packet containing operation time information, a third data packet containing an error alarm, a fourth data packet containing positional information, a fifth data packet containing filter/oil information, and a sixth data packet containing error history information. The data packets have different cycles depending on a use frequency. Although the information data packets are classified into six in the exemplary embodiment of the present disclosure, the number of information data packet types may be changed depending on a set-up. 
         [0033]    Further, the initially set transmission cycle for each information data packet is similarly stored even in the communication terminal  110 . For example, referring to  FIG. 4 , the first, second, and third data packets may be set 20 times per one week and the fourth, fifth, and sixth data packets may be set 10 times per one week. Hereinafter, in the exemplary embodiment, it will be described on the assumption that the initial set-up is shown as in  FIG. 4 . 
         [0034]    Further, the memory unit  158  includes a plurality of charge modes and stores a cycle value for each of the information data packets in each of the charge modes. The charge mode is a mode previously set by a provider. The cycle value for each data packet previously set for each charge mode may be stored in the memory unit  158  of the control server as described above, but may be stored not in the memory unit  158  but in a memory unit  104  of the communication terminal  110 . When cycle information for each data packet previously set for each mode is stored in the memory unit  104  of the communication terminal  110 , and a user or the provider selects a predetermined charge mode, the control server  150  transmits only the selected charge mode information to the communication terminal  110  and the communication terminal  110  receiving the corresponding information verifies the cycle information for each data packet according to the corresponding charge mode through the memory unit  104  to change the transmission cycle. 
         [0035]    Meanwhile, in the exemplary embodiment of the present disclosure, a case in which the charge mode is previously set as three modes such as a minimum charge mode, a medium charge mode, and a maximum charge mode will be described as an example. The charge modes may be further subdivided depending on the set-up. 
         [0036]    Herein, the minimum charge mode is a mode for setting a cycle for each data packet to a minimum data amount cycle and for example, the provider may previously set the first data packet to five times per one week, the second and third data packets to ten times per one week, the fourth data packet to ten times per one week, and the fifth and sixth data packets to be not sent, in regards to the cycle for each data packet set in the minimum charge mode. 
         [0037]    Further, the medium charge mode is a mode for setting the cycle for each data packet to a medium data amount cycle and for example, the provider may previously set each of the first, second, and third data packets to fifteen times per one week and each of the fourth, fifth, and sixth data packets to ten times per one week, in regards to the cycle for each data packet set in the medium charge mode. 
         [0038]    Lastly, the maximum charge mode is a mode for setting the cycle for each data packet to a maximum data amount cycle and for example, the provider may previously set each of the first, second, and third data packets to thirty times per one week and each of the fourth, fifth, and sixth data packets to twenty times per one week, in regards to the cycle for each data packet set in the maximum charge mode. 
         [0039]    The control unit  152  performs different controlling operations depending on whether a set-up for each packet is selected or a set-up for each charge mode is selected, from the user terminal  160 . Hereinafter, the controlling operation with selection will be described. 
         [0040]    Controlling Operation Depending on Set-Up for Each Packet 
         [0041]    The control unit  152  transmits the data packet including the cycle value for each packet to the communication terminal  110  through the transmission/reception unit  154  by using the mobile communication network  140  or the satellite communication network  130  when the set-up for each packet is selected from the user terminal  160  and the cycle value for each packet is set. 
         [0042]    That is, the cycle value for each packet selected by the user or provider is transmitted to the communication terminal  110  of the construction machinery and a program (firmware) of the communication terminal  110  that receives the corresponding cycle value modifies parameter values stored therein. That is, there are values of parameters A, B, C, D, E, and F respectively corresponding to the cycle values of the first, second, third, fourth, fifth, and sixth state information and the values are modified. Further, since the program of the communication terminal operates by referring to the values of parameters A, B, C, D, E, and F, the transmission cycle of the terminal may be changed. 
         [0043]    Controlling Operation Depending on Set-Up for Each Charge 
         [0044]    When the user terminal  160  selects a predetermined charge mode, the control unit  152  performs an operation for changing the transmission cycle of the communication terminal  110  so as to change each cycle for each information data packet to the cycle for each packet depending on the selected charge mode. 
         [0045]    As such, the method of changing the transmission cycle of the communication terminal  110  depending on selection of the charge mode in the control unit  152  includes a method of changing the transmission cycle by directly transmitting the cycle value for each data packet corresponding to the selected charge mode to the communication terminal  110  and a method of transmitting information on the selected charge mode and verifying and changing each cycle value for each data packet for the charge mode in the communication terminal  110 . 
         [0046]    The first method is a method that can be used when the cycle value for each data packet depending on the charge mode is stored in the memory unit  158  of the control server  150 . 
         [0047]    The control unit  152  verifies the cycle value for each data packet corresponding to the selected charge mode through the memory unit  158 , and transmits the verified cycle value for each data packet to the communication terminal  110  of the construction machinery by using the mobile communication network  140  or the satellite communication network  130  to change the transmission cycle of the terminal. 
         [0048]    Next, the second method is a method that can be used when the cycle value for each data packet depending on the charge mode is stored in the memory unit  104  of the communication terminal  110 . 
         [0049]    The control unit  152  transmits only the mode information of the information on the selected charge mode to the communication terminal  110  by using the mobile communication network  140  or the satellite communication network  130 , such that in the communication terminal  110 , a terminal program modifies the internal parameters by using the cycle value for each packet stored in the memory unit  104 . 
         [0050]    In the above description, the configuration to allow the user to select the cycle value for each packet or charge mode through the user terminal  160  is described, but the user may directly select the cycle value for each packet or the charge mode in the construction machinery  100  through an input device of the communication terminal  110  or an instrument panel input device of the construction machinery  100 . At the time of selecting the cycle value for each packet or the charge mode in the construction machinery  100 , the communication terminal  110  changes and sets current information data to the selected cycle value for each packet or charge mode without transmitting cycle setting information from the control server  150  to the communication terminal  110  as setting the cycle through the user terminal  110 . 
         [0051]    A process of managing transmission of communication data of the communication terminal  110  in the control server  150  configured as above will be described with reference to  FIG. 2 . 
         [0052]    Referring to  FIG. 2 , in step S 200 , the control server  150  allows the user terminal  160  to access the control server  150  through the Internet network  162  to examine whether selection for setting for each packet or for each mode. 
         [0053]    If there is selection for setting for each packet, the process proceeds to step S 202  and if there is selection for setting for each mode, the process proceeds to step S 204 . 
         [0054]    In step S 202 , the cycle value for each packet is inputted into the control server  150  from the user terminal  160  and the cycle value for each packet is set as the inputted cycle value for each packet and the process proceeds to step S 212 , such that the control server  150  transmits the set-up information for the transmission cycle to the communication terminal  110 . 
         [0055]    Meanwhile, there is selection for setting for each mode, such that in the step S 204 , the control server  150  examines which mode among the minimum charge mode, the medium charge mode, and the maximum charge mode is selected. That is when the user makes the selection for setting for each mode through the user terminal  160 , information on the selectable modes will be displayed through a screen and the user selects one of the charge modes. In this case, the user terminal  160  transfers the selected charge mode to the control server  150  to verify which mode is selected. 
         [0056]    If the minimum charge mode is selected, the process proceeds to step S 206 , a predetermined cycle value for each information data packet corresponding to the minimum charge mode is verified, and the current cycle value for each packet is changed and set to the verified cycle value for each packet. Thereafter, the process proceeds to step S 212  and the set cycle information for each packet is transmitted to the communication terminal  110 . 
         [0057]    If the medium charge mode is selected, the process proceeds to step S 208 , a predetermined cycle value for each information data packet corresponding to the medium charge mode is verified, and the current cycle value for each packet is changed and set to the verified cycle value for each packet. Thereafter, the process proceeds to step S 212  and the set cycle value for each packet is transmitted to the communication terminal  110 . 
         [0058]    If the maximum charge mode is selected, the process proceeds to step S 210 , a predetermined cycle value for each information data packet corresponding to the maximum charge mode is verified, and the current cycle value for each packet is changed and set to the verified cycle value for each packet. Thereafter, the process proceeds to step S 212  and the set cycle value for each packet is transmitted to the communication terminal  110 . 
         [0059]    Hereinafter, referring back to  FIG. 1 , an internal configuration of the communication terminal  110  will be described. 
         [0060]    In the case of the internal configuration of the communication terminal  110 , the communication terminal  110  includes the control unit  102 , the memory unit  104 , a mobile communication modem unit  106 , a satellite communication modem unit  108 , and an interface  109  for interfacing data transmission and reception with the construction machinery  100 . 
         [0061]    The mobile communication modem unit  106  is a modem for transmitting and receiving data through the mobile communication network  140  and the satellite communication modem unit  108  is a modem for transmitting and receiving data through the satellite communication network  130 . An example in which the communication terminal  110  according to the exemplary embodiment of the present disclosure includes both the satellite communication modem  108  and the mobile communication modem  106  to use both the satellite communication and the mobile communication is described, but the communication terminal  110  may be configured to include one of both modems to communicate through only the corresponding modem. 
         [0062]    The memory unit  104  stores the cycle value for each information data packet. Further, as described in the description of the memory unit  158  of the control server  150 , the cycle value for each information data packet may be previously stored in the memory unit  104  for each charge mode according to the set-up. 
         [0063]    The control unit  102  changes and sets the current transmission value for each information data packet according to the cycle value for each packet received from the control server  150  to the received cycle value for each packet, and transmits the information data packets of the construction machinery to the control server  150  according to the changed and set transmission cycle. 
         [0064]    Further, when receiving predetermined charge mode information from the control server  150 , the control unit  102  verifies the previously stored cycle value for each information data packet according to the corresponding charge mode, changes and sets the current cycle value for each packet to the verified cycle value for each packet as the transmission cycle, and transmits the data packets including the information of the construction machinery to the control server  150  according to each changed transmission cycle value for each data packet. 
         [0065]    A process of transmitting a state information data packet to the control server  150  according to the cycle value for each packet in the communication terminal  110  configured as above will be described with reference to  FIG. 3 . 
         [0066]    Referring to  FIG. 3 , when the communication terminal  110  receives the data packet including the cycle value for each packet transmitted to change the transmission cycle from the control server  150  in step S 300 , the process proceeds to step S 302 , and changes and sets the cycle value for each packet by using the received cycle value for each packet and if not, the process proceeds to step S 308 . 
         [0067]    In step S 308 , the communication terminal  110  examines whether the information on the predetermined charge mode for changing the transmission cycle is received. 
         [0068]    If the predetermined charge mode information is received from the control server  150 , the process proceeds to step S 310  in which the cycle value for each packet corresponding to the received charge mode is verified, and the verified cycle value for each packet is changed and set, and thereafter, the process proceeds to step S 303 . 
         [0069]    In step S 303  performed in steps S 302  and S 310 , the communication terminal  110  transmits the information data packets according to the changed transmission cycle. 
         [0070]    Thereafter, the process proceeds to step S 304  to examine whether a significant event occurs in the construction machinery  100 . At this time, the significant event represents an event such as an error or theft to frequently transmit the corresponding state information regardless of the set cycle for each packet or charge mode. 
         [0071]    If it is sensed that the significant event occurs in the construction machinery according to the examination result in step S 304 , the process proceeds to step S 305  and the communication terminal  110  verifies a transmission cycle value for information on the corresponding event. Thereafter, the communication terminal  110  transmits a data packet associated with the significant event to the control server  150  with the verified transmission cycle value. 
         [0072]    For example, in the case in which the error occurs as the significant event, the third data packet containing the error alarm changes the transmission cycle to transmit the third data packet with a predetermined transmission cycle associated with the error occurrence event without depending on the predetermined set-up for each packet or set-up for each mode. For example, the third data is transmitted at ten times per one week in the minimum charge mode, but differently from that, the transmission cycle is changed to be a cycle in which the third data is transmitted at seven times per one day. 
         [0073]    Further, in the case in which the machinery is thieved as the significant event, although the minimum charge mode is set and thus the fourth data packet containing the positional information is set to be transmitted at ten times per one week, when the theft event occurs, the control server  150  can verify event associated information more specifically by changing the cycle so as to transmit the fourth data packet more frequently regardless of the set charge mode by changing the cycle so as to transmit the fourth data packet at ten times per one day. 
         [0074]    As described above, when the significant event occurs, the communication terminal  110  may change a cycle for only the data packet associated with the corresponding event and in addition, reduce a data amount of a packet associated with the corresponding event. For example, the fourth data packet containing the positional information may include various pieces of information such as longitude, latitude, time, a direction, velocity, and the like, but in the case of theft, the direction and velocity information are unnecessary, and as a result, only the longitude, latitude, and time information are included in the fourth data packet to be transmitted except for the unnecessary information. That is, only necessary information is included in the data packet, such that the data amount may be reduced and transmitted. 
         [0075]    Thereafter, when the communication terminal is off in step S 306 , the process ends and if not, the process proceeds to step S 300 . 
         [0076]    In the exemplary embodiment of  FIG. 3 , the case in which cycle value set-up for the significant event such as the error or theft event is stored in the communication terminal  110  and when the significant event occurs, the data packets associated with the error and the theft are transmitted to the control server  150  with a predetermined cycle value in the communication terminal  110  has been described as an example. 
         [0077]    However, the control server  150  examines whether the significant event occurs in the construction machinery  100  and when it is sensed that the significant event occurs, the control server  150  verifies the transmission cycle value for the information associated with the corresponding event, such that the communication terminal  110  may transmit the data packet containing the verified transmission cycle value to transmit the data packets associated with the error and the theft with the received cycle value to the control server  150 . 
         [0078]    Further, the cycle value is restored and set to the cycle value for each data packet before the change again when the significant event is cancelled. 
         [0079]    As described above, although certain exemplary embodiments of the present disclosure have been described in detail, it is to be understood by those skilled in the art that the spirit and scope of the present disclosure are not limited to the certain exemplary embodiments, but are intended to cover various modifications and changes without departing from the gist. 
         [0080]    Accordingly, since the above-mentioned exemplary embodiments are provided to inform those skilled in the art of the scope of the present disclosure, it should be understood that they are exemplary in all aspects and not limited and the present disclosure is just defined by the scope of the appended claims. 
         [0081]    The present disclosure can be applied to a system for managing information of a construction machinery.
