(Service) is provided. And, as shown in Patent Document 1, an IC tag is attached to a positioning terminal so that it can cope with an environment unsuitable for positioning by the positioning means such as underground, and the position is determined from the information of the IC tag when indoors. There has also been proposed a composite position processing system that detects the above.
JP 2001-339754 A

  The positional information management system configured as described above can be roughly divided into the following two. First, as widely used in general mobile phone terminal devices, a user holding a positioning terminal acquires location information as necessary and displays it on a map screen downloaded from a host device. That's it.

  On the other hand, the second is mainly used for security purposes, and the positioning terminal performs positioning at predetermined time intervals and notifies the positioning result to the host device on the management center side. On top of this, applications that use positions such as displaying the position of the person holding the terminal or the object attached with the terminal on the map screen or notifying the guardian when leaving the set range are performed. is there.

  In the second position information management system in which positioning is performed unintentionally by the user, when the user uses the function of the system as described above, a position information display device (generally a client terminal of the system) The personal computer) and the positioning terminal itself. Therefore, for example, parents forget to turn on their power when they go out of their children, forgetting to turn on the power, cannot use the service, or forget to turn off the power when they go home As a result, there is a problem that the communication cost is excessive, or the battery is unexpectedly consumed and cannot be used. In addition, there is a problem that the power supply is kept on despite being in the school, resulting in unnecessary communication cost and increased battery consumption.

  On the other hand, in order to prevent such an operation error, there is also a method in which an operation schedule is registered in advance in the host device on the management center side, and the operation of the positioning terminal is controlled by a command from the host device. However, in such a configuration, there is a problem that the user has to perform a schedule registration operation each time even in regular use. Also, sudden changes in the schedule cannot be handled, the timing of starting and ending is ambiguous, and the positioning terminal will be operated more than necessary, which also shortens the battery life of the positioning terminal, There is also the problem of increasing costs.

  An object of the present invention is to provide a position information management system that can easily and appropriately use the functions of the system.

  The position information management system of the present invention comprises a positioning terminal comprising at least a positioning means, a communication means for transmitting the positioning result to a host device via a public wireless communication line, and a control means for controlling them.

In the positional information management system, the positioning terminal is provided with a wireless tag, and a position-fixed wireless unit whose position is recognized in advance is provided correspondingly, and the position-fixed wireless unit is connected to the wireless tag and short-range wireless. Identification information (terminal ID) regarding the positioning terminal obtained through communication is transmitted to the host device via a wired or wireless public wireless communication line. The host device transmits a control command to be executed by the control means of the positioning terminal via the public wireless communication line on the premise of the captured position of the received identification information before the positioning terminal.

  Therefore, for short-range wireless communication, it is confirmed that the positioning terminal is in a narrow range from the fixed position wireless unit regardless of whether it is indoors or outdoors. And by assuming the previous capture position of the positioning terminal, you can determine whether you are going out or returned, for example, in some cases you can accurately determine such a situation that should be completely reversed, An accurate control command can be given to the control means. Thereby, the function of the location information management system can be used easily and appropriately. In addition, the amount of communication can be reduced, and the cost can be reduced.

  In the position information management system of the present invention, the wireless tag is a contactless IC card, and the position fixing wireless unit is a reader device for the contactless IC card.

  According to said structure, a system can be easily constructed | assembled by using a non-contact IC card and its reader apparatus.

  Furthermore, in the location information management system of the present invention, the wireless tag is a wireless LAN device including a wireless LAN communication unit and a wireless LAN control unit, and the position fixing wireless unit is an access point of the wireless LAN. It is characterized by that.

  According to the above configuration, it is possible to use an existing wireless LAN access point in the position fixing wireless unit, and it is easy to construct and expand the system.

  In the position information management system of the present invention, the control means realizes the function of the wireless LAN control unit.

  According to said structure, when using the existing wireless LAN access point, the structure of a positioning terminal can be simplified and the cost of a positioning terminal can be reduced.

  The position information management system of the present invention measures the position of its own device by GPS reception or communication with a base station of a mobile phone at a positioning terminal, and the host device via the public wireless communication line such as the mobile phone In the position information management system for transmitting to the positioning terminal, the positioning terminal is provided with a wireless tag, and a position-fixed wireless unit whose position is recognized in advance is provided correspondingly, and the position-fixed wireless unit is connected to the wireless tag. The identification information (terminal ID) regarding the positioning terminal obtained by performing short-range wireless communication with the host terminal is transmitted to the host device, and the host device presupposes the captured position of the received identification information before the positioning terminal. A control command to be executed by the control means is transmitted via the public wireless communication line.

  Therefore, for short-range wireless communication, it is confirmed that the positioning terminal is in a narrow range from the fixed position wireless unit, both indoors and outdoors, and assuming the previous acquisition position of the positioning terminal, for example, It is possible to determine whether to go out or to return. In some cases, it is possible to accurately determine such a situation in which completely reverse control should be performed, and to give an accurate control command to the control means.

In the unit 4, it is possible to recognize which wireless tag 14 has been detected. The wireless tag 14 does not require a power source or the like, and includes a positioning unit 11, a wireless communication unit 12, and a terminal control unit 13. The wireless tag 14 is controlled by a control command from the management server device 5 according to a schedule registered in advance. It may simply be additionally mounted, for example, affixed in a seal form, to a portable radio terminal for a possible conventional location information management system. Therefore, in the portable wireless terminal 1 of the present invention, the control program of the terminal control unit 13 does not need to be changed, and an existing configuration can be used.

  FIG. 2 is a diagram illustrating an example of registered contents of a control command for the portable wireless terminal 1 in the management server device 5. Note that the control command depends on the function of each portable wireless terminal 1. As shown in FIG. 2, when outputting the control command, the management server device 5 determines whether each portable wireless terminal 1 is captured by the position-fixed wireless unit 4 having which unit ID this time and the previous time. Then, a control command to be executed by each portable radio terminal 1 is created and transmitted from the radio base station 2.

  FIG. 3 is a diagram showing a change in control command with the passage of time in the following system operation example. FIG. 4 is a sequence diagram according to the operation example. In this example, the portable wireless terminal 1 has a periodic positioning function for periodically transmitting the result of positioning by the positioning unit 11 to the management server device 5 via the wireless base station 2, and the portable wireless terminal 1 appears outside the set area. It is assumed that there are an area monitoring function for notifying that, and a periodical positioning and area monitoring operation are stopped, a standby function that can respond only to a call from the radio base station 2 and has low power consumption.

  This operation example represents an example in which a user holding the portable wireless terminal 1 moves from point A to point C via point B, and the position-fixed wireless unit 4 installed at each point A, B, C is shown. IDs are represented by the same symbols (A), (B), and (C), respectively. First, for each portable wireless terminal 1, a control command to be transmitted is associated with each unit ID of the position-fixed wireless unit captured this time and the position-fixed wireless unit captured last time and registered in the management server device 5. Keep it.

  When the movement is started, the portable wireless terminal 1 is captured in the vicinity of the position-fixed wireless unit (A) at the point A. Thereby, the terminal ID (12345) of the portable wireless terminal 1 held in the wireless tag 14 is received by the position fixing wireless unit (A), and the terminal ID is transmitted to the management server device 5 together with the unit ID (A). Is done. The management server device 5 that has received the terminal ID and the unit ID (A) as the sample 1 is based on the previous capturing position (previous unit ID) of the portable wireless terminal 1 (in this example, the previous time). The control command to be executed by the portable wireless terminal 1 is searched from the control command table registered in the management server device 5. Then, the control command (1: periodic positioning) obtained by the search is wirelessly transmitted via the wireless base station 2 that can currently communicate with the portable wireless terminal 1. If there is no corresponding control command, nothing is transmitted, or a control command registered in advance is transmitted. A plurality of control commands may be used.

  The portable wireless terminal 1 that has received the control command continuously executes the corresponding function (periodic positioning) until the next unit ID is detected and a new control command is output from the management server device 5, and is necessary. In response, the result is sent back to the management server device 5 (for regular positioning, positioning may be performed periodically, and the positioning result may be transmitted each time, after a predetermined number of samples or data for a predetermined time has been obtained. May be sent.) The result may be displayed on a position information display device (generally, a client personal computer of the system) that can communicate with the management server device 5 and can be confirmed by a guardian or the like, if necessary.

  Subsequently, when the mobile wireless terminal 1 moves and is captured in the vicinity of the next fixed position wireless unit (B) and the terminal ID held in the wireless tag 14 is received, the terminal ID becomes the unit ID (B ) Is transmitted to the management server device 5. Receiving this, the management server device 5 receives the control position to be executed by the portable wireless terminal 1 on the premise of the previous capture position (previous unit ID (A)) of the portable wireless terminal 1. Search from the control command table registered in. The control command (2: area monitoring) obtained by the search is wirelessly transmitted via the wireless base station 2 that can currently communicate with the portable wireless terminal 1. The mobile wireless terminal 1 that has received the control command executes the corresponding function (area monitoring), and returns the result to the management server device 5 (for area monitoring, a signal indicating that is transmitted when the mobile station 1 leaves the area). No reply unless you go out of the area.)

  Further, when the portable wireless terminal 1 moves and is captured in the vicinity of the next fixed position wireless unit (C) and the terminal ID held in the wireless tag 14 is received, the terminal ID is combined with the unit ID (C). It is transmitted to the management server device 5. Receiving this, the management server device 5 gives a control command to be executed by the portable wireless terminal 1 on the premise of the previous capture position (previous unit ID (B)) of the portable wireless terminal 1. Search from the control command table registered in. The control command (3: standby) obtained by the search is wirelessly transmitted via the wireless base station 2 that can currently communicate with the portable wireless terminal 1. The mobile wireless terminal 1 that has received the control command executes the corresponding function (standby), and returns the result to the management server device 5 (replying a response when the standby mode is entered for standby, or periodically It may reply that it is in the standby mode, or may not respond.)

  When the same terminal ID is received again by the position fixing wireless unit (C) on the return path, the management server device 5 searches for the control command (4: periodic positioning) to be executed by the portable wireless terminal 1 and wirelessly transmits it. Then, the portable wireless terminal 1 is restarted.

  FIG. 5 is a flowchart showing the operation of the management server device 5. In step S1, it is determined whether any one of the wireless tags 14 has been detected by any one of the fixed position wireless units 4, and if detected, the process proceeds to step S2, and the previous unit ID, current unit ID, and the like as described above. The control command corresponding to is retrieved from the control command table, wirelessly transmitted via the radio base station 2, and the process returns to step S1.

  On the other hand, if the wireless tag 14 is not detected in step S1, the process proceeds to step S3, and has there been any trigger from the portable wireless terminal 1 such as receiving a positioning result or receiving a signal indicating that it has gone out of the area? If not, it is further determined in step S4 whether or not a trigger based on a pre-registered schedule has occurred. If not, the process directly returns to step S1. On the other hand, when a trigger is generated from the portable wireless terminal 1 in step S3 and when a schedule trigger is generated in step S4, the process proceeds to step S5, and control commands corresponding to those triggers are displayed in the control command table. And wirelessly transmitted via the wireless base station 2, the process returns to step S1.

  As described above, the position information management system of the present invention includes the positioning unit 11, the wireless communication unit 12, and the terminal control unit 13, and according to a control command from the management server device 5 according to a previously registered schedule or the like. A wireless tag 14 is additionally mounted on a portable wireless terminal for a position information management system that can be controlled, and a fixed position wireless unit 4 that performs short-range wireless communication with the wireless tag 14 is provided at a known position. However, when the terminal ID is received by the fixed position wireless unit 4, a control command to be executed by the terminal control unit 13 is transmitted on the premise of the previous capture position. Regardless of whether the portable wireless terminal 1 is within a narrow range from the fixed position wireless unit 4 and further assuming the previous capture position, for example, Can be determined whether or not to return, and in some cases, it is possible to accurately determine such a situation where the reverse control should be performed, and to give an accurate control command to the terminal control unit 13 it can. Thereby, the function of the location information management system can be used easily and appropriately. In addition, the amount of communication can be reduced, and the cost can be reduced.
