The mobile object position information management system A is a system that manages the position of a visitor to the management area using a large building such as a research building or a factory as a management area. In such a management area, since there are not only employees who enter on a daily basis, but also customers and suppliers who enter temporarily, there are many visitors in a large building. In the building, there are places where outsiders are not allowed to enter and places where things that are trade secrets are placed. The mobile location information management system A detects and manages the positions of all the occupants in the management area in order to prevent access to inappropriate places and to grasp the current position of each occupant. . As shown in FIG. 1, a mobile location information management system A includes a plurality of fixed transmitters 1 (1a, 1b, 1c, 1d), a mobile transmitter 2, a mobile communication terminal 3, a management terminal 4, a communication network. 5 and a display device 6.

  A plurality of fixed transmitters 1 are disposed in the management area and transmit position information as radio signals at a constant period (for example, every 10 minutes). The position information is information indicating a position where the fixed transmitter 1 is arranged, and is, for example, information indicating a building number, a floor number of a building, a room number, a position in a room, and the like. Note that the fixed transmitter 1 may transmit unique identification information, and the management terminal 4 may acquire the associated position information from the identification information. Also in this case, the identification information of the fixed transmitter 1 is information indicating the arrangement position indirectly, and can be said to be position information. The communication distance of the fixed transmitter 1 is, for example, about 10 m, and can be changed by setting.

Thus, the administrator can grasp the current positions of the visitors 20 and 30 by looking at the monitor of the display device 6.

  FIG. 6 is an example of a flowchart for explaining the moving object detection processing in the moving object position information management system A. FIG. 1A shows a process performed by the fixed transmitter 1, FIG. 2B shows a process performed by the portable transmitter 2, and FIG. FIG. 4D shows the processing performed by the management terminal 4.

  As shown in FIG. 6A, the fixed transmitter 1 transmits the position information as a radio signal to a predetermined range at a constant period (S11). Note that while the management area is closed, such as at night, the fixed transmitter 1 may stop transmitting position information. Further, as shown in FIG. 6B, the portable transmitter 2 transmits the identification information as a radio signal to a predetermined range in a constant cycle (S21). The portable transmitter 2 is turned on only when used, and transmits identification information.

  When the portable communication terminal 3 is turned on when used, the process shown in FIG. 6C is started. As shown in FIG. 6C, when the portable communication terminal 3 receives the identification information from the portable transmitter 2 (S31), the portable communication terminal 3 stores the identification information in the storage unit 33 (S32). Then, it is determined whether or not the position information has been received from the fixed transmitter 1 (S33). If the position information has not been received (S33: NO), the process returns to step S31 and repeats steps S31 to S33. On the other hand, when the position information is received (S33: YES), the position information is stored in the storage unit 33 (S34), and the position-related information is generated (S35). The position-related information is generated based on the position information and the identification information stored in the storage unit 33. In other words, every time the position information is received, the position-related information is generated based on the identification information received during a period from the reception of the previous position information to the reception of the current position information and the position information received this time. You. Next, the mobile communication terminal 3 transmits the generated position-related information to the management terminal 4 (S36), and returns to step S31. Note that the timing of generation and transmission of the position-related information is not limited to the above. For example, at each predetermined timing, position-related information may be generated and transmitted based on the position information received most recently and the identification information received during the timing.

  When the power is turned on when the management terminal 4 is used, the management terminal 4 starts the processing shown in FIG. As shown in FIG. 6D, the management terminal 4 determines whether or not position-related information has been received from the mobile communication terminal 3 (S41). If the position-related information has not been received (S41: NO), the process returns to step S41 and repeats the determination. On the other hand, when the position-related information is received (S41: YES), the position-related information is stored in the storage unit 43 (S42). Then, the management terminal 4 reads out the latest position-related information from the storage unit 43 (S43), generates information indicating the position of each of the visitors 20 and 30 based on the position-related information, and displays the information on the display device 6. The positions of the visitors 20 and 30 are displayed (S44), and the process returns to step S41. This allows the management terminal 4 to display the current positions of the visitors 20 and 30 on the display device 6 each time the management terminal 4 receives the position-related information from the mobile communication terminal 3. The display on the display device 6 may be updated at each predetermined timing.

  Note that the processing shown in each flowchart of FIG. 6 is an example, and the moving object detection processing is not limited to the above.

  According to the present embodiment, the mobile communication terminal 3 always carried by the visitor 30 is provided with the position information transmitted by the fixed transmitter 1 and the identification transmitted by the portable transmitter 2 carried by the temporary visitor 20. The information is received, and the position-related information is transmitted to the management terminal 4. Therefore, the management terminal 4 can detect the position of the mobile communication terminal 3, that is, the position of the regular visitor 30 accompanying the mobile communication terminal 3, based on the position information of the received position-related information. Further, based on the received position-related information, the management terminal 4 determines the position of the portable transmitter 2 from the position of the portable communication terminal 3, that is, the position of the temporary visitor 20 entraining the portable transmitter 2. Can be detected. That is, the mobile location information management system A can manage the locations of the visitors 20 and 30. In addition, since the unit price of the portable transmitter 2 accompanying the temporary visitor 20 and the fixed transmitter 1 arranged in the management area is low, the conventional mobile object position information management system (FIG. 7A, As compared with (b)), the introduction cost of the mobile object position information management system A can be suppressed. In addition, since the temporary entrant 20 who is an outsider is not the expensive portable communication terminal 3 but the inexpensive portable transmitter 2, troubles such as breakage or loss are not a serious problem.

  Further, according to the present embodiment, the management terminal 4 generates information indicating the positions of the visitors 20 and 30 based on the latest position-related information, and outputs the information to the display device 6. The display device 6 adds, based on the information indicating the position of each of the entrants 20 and 30 input from the management terminal 4, a display indicating each of the entrants 20 and 30 on the map of the management area so as to be identifiable. Display on the monitor. Thus, the administrator can grasp the current positions of the visitors 20 and 30 by looking at the monitor of the display device 6. Further, it can be confirmed whether or not the temporary visitor 20 is always accompanied by the temporary visitor 30.

  In the present embodiment, the case where the position of each of the entrants 20 and 30 is detected, that is, the case where the mobile object whose position is to be detected is a person, is not limited to this. The moving object may be a bicycle, motorcycle, car, or the like other than a person, or may be an object carried by a person. Further, these moving objects may be mixed. For example, a research building for measuring the performance of a vehicle is a management area, and the portable transmitter 2 is installed in a vehicle brought in as a research target instead of the temporary resident 20, and the resident 30 constantly moves the vehicle. And the case of attending the measurement. In this case, the vehicle corresponds to the “first moving body” of the present invention. Also in this case, the administrator can grasp the current position of the vehicle by looking at the monitor of the display device 6.

  In the present embodiment, the case where the portable transmitter 2 selects any one of the position information based on the radio wave intensity of the received radio wave when the communication area of the fixed transmitter 1 partially overlaps has been described. Not limited. For example, when the portable transmitter 2 receives a plurality of pieces of position information, the portable transmitter 2 may store the position information based on the center position of the position related to the position information. Further, the position information may be stored based on a position corrected according to the radio wave intensity of the received radio wave, instead of the simple center position.

  In the present embodiment, in the management area, the operation rule is that the temporary visitor 20 is always present to the temporary visitor 20, but the present invention is not limited to this. Even if there are no such operational rules, if there are many permanent visitors 30 in the management area, the temporary visitors 30 are often close to the temporary visitors 20, so the temporary visitors 20 The position can be detected.

  In the present embodiment, the case where a large building such as a research building is used as the management area has been described, but the present invention is not limited to this. For example, an amusement park or an event venue may be used as the management area. In this case, the fixed transmitters 1 are arranged at predetermined intervals, the staff and the like are accompanied by the portable communication terminal 3, and the visitors are accompanied by the portable transmitter 2, so that the introduction cost can be suppressed and the staff and the visitor can be controlled. Can manage the position of the person.

  In the present embodiment, the case where the mobile communication terminal 3 is always entrained by the entrant 30 and the portable transmitter 2 is entrained by the temporary entrant 20 has been described, but the present invention is not limited to this. For example, in a management area where temporary entrants 20 are not allowed to enter, a mobile communication terminal 3 is entrained by an employee (ordinarily entrant 30) or higher, and a mobile communication terminal is assigned to other employees (always entrants 30). 3 may be included.
