Next, the operation of the position tracking system of the present invention using the GPS and the wireless terminal will be described with reference to FIG.

The location tracking system using GPS and wireless communication according to the present invention is to identify and transmit a periodic movement state for one object (mode 1), to identify and transmit only the current position (mode 2) to a plurality of objects. In this case, the periodic movement state can be distinguished by the mode (mode 3). Mode 1 and mode 2 are transmitted by the ARS 16 method, and mode 3 is transmitted by the data transmission method.

First, in mode 1, when the service request information is input from the wireless terminal 4 or the position receiving apparatus 5 to the input unit 13 of the service center 1 in the service start step (S1) (S2), the control unit ( 14 determines whether the signal requires information collective transmission, that is, output to the ARS 16 or collectively by the data transmission method (S3). If it is not a batch transmission, it is determined whether or not the location information is periodically supplied to the service center at a predetermined time interval (for example, 10 minutes, 30 minutes, etc.) (S4). If NO is set, mode 2 is transmitted in which only the current position is transmitted. In the case of Mode 1, the controller 14 checks the wireless terminal code again (S6), and then the wireless terminal 4 calculates the location information using the information from the GPS satellite 3 (S7) and the calculated information. Is periodically transmitted to the GIS 11 of the service center 1 (S8), and the periodic movement situation of the moving object is converted into a position on the map (S9). Then, the control unit 14 determines whether or not the data transmission request is from the position receiving apparatus 5 (S10), and if YES, checks the unique code of the position receiving apparatus 5 (S11), and the ARS (16) transmission method. After completion of the transmission (S12) through the output unit 15 (S208), and if the determination in S10 is NO, and immediately proceeds to the end step (S208).

On the other hand, if the determination in step S4 is NO, it is determined as mode 2 (S101), after confirming the code of the wireless terminal 4 (S102), the service center 1 requests the location information from the wireless terminal 4; (S103) Next, the wireless terminal 4 calculates the current position information using the GPS satellite 3 (S104), and transmits the current position information of the moving object to the GIS 11 of the service center 1 ( S105), the information is converted into a position on the map (S106). After going to step S10 as in Mode 1, if there is no service request of the customer immediately proceeds to the end step (S208), if there is a service request to check the unique code of the position receiving device (5) (S11) ARS (16) The transfer is completed (S12), and the process proceeds to the end step S208.

If the determination in step S3 is NO, then information batch transmission is required, so it is determined as mode 3 (S201), the unique code of the position receiving apparatus 5 is confirmed (S202), and the unique code of the wireless terminal 4 is determined. After confirming (S203), the wireless terminal 4 calculates the current position information using the GPS satellites (S204), and periodically transmits the calculated information to the GIS 11 of the service center (S205) (S205). In step S206, the periodic movement state of the moving object is converted into a position on the map. After the data transmission method is selected and the transmission is completed through the output unit 15 (S207), the process proceeds to the end step (S208).

According to this configuration, the present invention can provide a quality service to customers who need to know the dynamics of the individual, such as sales personnel.
