Description

  The present invention relates to a position detection system, and more particularly to efficiently provide a plurality of independent services in a position detectable area by reducing signal interference accompanying an increase in the density of mobile terminals in the position detectable area. The present invention relates to a position detection system.

  In production sites such as factories, products are often manufactured while moving through a plurality of production processes. For this reason, a small transmitter with a built-in IC tag or the like is attached to a part or the product itself being manufactured in a factory, etc., to track the position of the product or part moving in the factory. Therefore, many traceability systems that can manage products are used.

  In addition, it is necessary to allow only certain persons to pass through the ticket gates of stations where many people pass and entrance / exit gates for special events. For this reason, an access control system is used in ticket gates, entrance gates, etc. that allows a person who passes through the passage to have a transmitter as described above, and can determine the pass authority of the passer and control the pass. May have been.

  In the traceability system and the access control system as described above, a transmitter is provided for an object or person to be moved, and a receiver receives a signal transmitted from the transmitter to obtain position information of the moving object. Detected. Usually, a signal necessary for position detection is transmitted from a transmitter at regular time intervals. For this reason, even if an object or a person cannot move to a place other than the area where the receiver can receive the signal, that is, the service providing area where the service can be provided, the position cannot be detected from the transmitter. The signal continues to be transmitted. When moving to a location other than the service provision area, if a similar frequency is used in another service provision area, the signal in the service provision area may be disturbed or the performance of the service processing system may be affected. It was a cause of lowering. In view of this, a system has been proposed in which a signal transmitted from a transmitter can be stopped in places other than the service providing area.

  For example, Patent Document 1 discloses an article management tag and system in which a vibration sensor capable of detecting vibration is incorporated in an active tag and a communication mode is switched depending on a vibration state detected by the vibration sensor. In this article management tag and system, for example, when an object or a person moves, the active tag is switched from the low power consumption mode to the communication mode when the vibration sensor detects vibration. If no vibration is detected for a predetermined time, the active tag is switched from the communication mode to the low power consumption mode again.

  Further, in Patent Document 2, a transmitter receives a signal transmitted from a fixed base station, determines whether or not it is in a communication area with the fixed base station, and intermittent when it is outside the service providing area. A location detection system that extends battery life by transmitting and receiving signals and transmitting an identification signal when in a service providing area is disclosed.

Patent Document 3 discloses a tag system that can change the activation cycle of the IC tag itself by periodically transmitting a beacon signal including a command or ID from the tag reader to the IC tag. Yes. As a result, signal interference due to an increase in the density of the IC tag in the service providing area can be reduced, and power consumption of the IC tag can be reduced.

  However, in the article management tag and system disclosed in Patent Document 1, since transmission of a signal is started by vibration, a signal is transmitted even when the active tab is vibrated in a place other than the service providing area. Therefore, there is a possibility that it may interfere with signals in other service providing areas.

  Further, in the location detection system disclosed in Patent Document 2, since it is necessary to transmit a signal for specifying that the service is provided from a fixed base station, the number of transmitters that can be accommodated decreases. There was a problem. Further, since it is assumed that the position detectable area and the service providing area are the same, it has been difficult to efficiently provide a plurality of services simultaneously in one position detectable area.

  In the tag system disclosed in Patent Document 3, although the activation cycle of the tag itself can be changed for each position detection area unit, the tag operates according to the changed activation cycle. Similar to the location detection system disclosed in, the number of mobile terminals with built-in IC tags can be reduced, and multiple independent services can be efficiently provided within the location detection area. It was difficult to do.

  In view of the above problems, an object of the present invention is to reduce signal interference caused by an increase in the density of mobile terminals in a position-detectable area, and efficiently perform a plurality of independent services in the position-detectable area.

A beacon is provided for each service provision area. When the mobile terminal receives the beacon signal transmitted from the beacon, the operation mode information selection unit specifies the operation mode information stored in the service providing database, and the mobile terminal signal corresponds to various services. Make or stop calls. The mobile terminal transmits a mobile terminal signal only when the mobile terminal is present in the service providing area existing in the position detectable area, and the mobile terminal stops transmitting the mobile terminal signal in other areas. As a result, it is possible to reduce signal interference accompanying an increase in the density of mobile terminals in the position detectable region, and to efficiently provide a plurality of independent services in the position detectable region.

  The second position detection system (corresponding to claim 2) is characterized in that, in the above configuration, the operation mode information is a transmission period, a transmission output level and a transmission time of a mobile terminal signal set for each service. And

  In the fifth position detection system (corresponding to claim 5), in the above configuration, the transmission means has a service providing database in which operation mode information corresponding to service identification information included in the beacon signal received by the beacon signal receiving means is provided. When not present in the mobile terminal, transmission of the mobile terminal signal is stopped.

The operation mode information corresponding to the service identification information included in the beacon signal is selected, and the transmission means transmits the mobile terminal signal based on the operation mode information.

  In the above position detection system, even if the beacon signal receiving unit receives a beacon signal including a plurality of different service identification information, one operation mode information is specified based on the energy level of the beacon signal. A service can be provided efficiently by providing a plurality of service providing areas in the detectable area.

  Further, even when the beacon signal receiving unit receives a beacon signal including a plurality of different service identification information, the operation mode information is identified based on the energy level or the operation priority information of the received beacon signal. A plurality of services can be efficiently provided in the position detectable region.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  First, the configuration of the position detection system according to the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram showing a configuration of a position detection system according to the present invention.

  A position detection system 10 shown in FIG. 1 includes fixed base stations 11a to 11d, beacons 12a to 12d, mobile terminals 13-1 to 13-n, a mobile terminal position detection unit 14, and service control units 15a to 15d. Composed.

  The fixed base stations 11a to 11d receive mobile terminal signals transmitted from a plurality of mobile terminals 13-1 to 13-n. By these fixed base stations 11a to 11d, it is possible to receive mobile terminal signals transmitted from the mobile terminals 13-1 to 13-n existing in the position detectable region 21 indicated by a two-dot broken line in the figure. Thus, the mobile terminal position detector 14 described later detects the position information of the mobile terminals 13-1 to 13-n existing in the position detectable area 21. Note that the number of fixed base stations 11a to 11d may be determined according to the area of the position detectable region 21, the accuracy of the fixed base stations 11a to 11d, and the like.

  The beacons 12a to 12d are, for example, radio wave beacons and optical beacons, and are provided in service providing areas 22a to 22d indicated by dashed lines in the figure, which are areas that provide various services using the position detection system 10, and mobile terminals A beacon signal including service identification information corresponding to various services is transmitted to the 13-1 to 13-n by radio waves, light or the like at regular time intervals. One service identification information is assigned to one service. The service here is realized by using the position detection function of this system, and is an example, but it is an access control system that controls passers-by in passways, etc. A guidance system that provides guidance information on goods, products, and the like. Further, even one service may have a sub-service option that provides different services depending on, for example, the authority of service recipients 24-1 to 24-n.

  The mobile terminals 13-1 to 13-n can receive beacon signals in the beacon signal receivable areas 23a to 23d indicated by dotted lines in the figure or in the peripheral area. Further, the arrangement positions of the beacons 12a to 12d, the output levels of the beacon signals, and the like are determined so that the service providing areas 22a to 22d are included in the beacon signal receivable areas 23a to 23d. The arrangement positions of the beacons 12 a to 12 d are not limited to the position detectable area 21 but also include the peripheral area of the position detectable area 21. In a service performed at the end of the position information detection area 21, a beacon may be provided in a peripheral area of the position detectable area 21 like the beacon 12c. Further, for example, the service identification information included in the beacon signal may be switched and transmitted at regular time intervals to provide different services in one service providing area.

  The mobile terminals 13-1 to 13-n have built-in active tags capable of communicating with the fixed base stations 11a to 11d on the order of several tens of meters to several hundreds of meters, and the persons 24-1 to 24- n, or attached to an object such as a luggage or a product, and moves together with the object to be moved. The number of mobile terminals 13-1 to 13-n varies depending on the number 24 of people present in the position detectable area 21.

  The mobile terminals 13-1 to 13-n receive beacon signals transmitted from the beacons 12a to 12d, and are set for each service or sub service based on service identification information included in the beacon signals. Based on the information, a mobile terminal signal including mobile terminal identification information, which is information for identifying the mobile terminal, is transmitted or stopped at regular time intervals. If the mobile terminals 13-1 to 13-n have not received a beacon signal immediately after activation, the mobile terminals 13-1 to 13-n are in a state where transmission of the mobile terminal signal is stopped. The mobile terminal signals output from the mobile terminals 13-1 to 13-n and the beacon signals transmitted from the beacons 12a to 12d cause signal interference in the position information detection region using different frequency bands. It is preventing.

  The mobile terminal location detection unit 14 obtains location information and mobile terminal identification information indicating the locations of the mobile terminals 13-1 to 13-n based on the mobile terminal signals received by the fixed base stations 11a to 11d. It is to detect.

  The service provision control units 15a to 15d generate and output beacon signals transmitted from the beacons 12a to 12d provided in the service provision areas 22a to 22d. The service providing control units 15a to 15d control devices necessary for providing a service or sub-service based on the location information and mobile terminal identification information detected by the mobile terminal location detecting unit 14. is there. For example, in the case of an access control system, these devices are doors that can be opened and closed provided at the gate of the passage, various sensors provided near the passage, and the like. Each time the fixed base stations 11a to 11d receive mobile terminal signals, location information and mobile terminal identification information are output from the mobile terminal location detector 14, but the contents and characteristics of the service or sub-service to be provided, etc. Accordingly, unnecessary location information and mobile terminal identification information may be ignored in the service provision control units 15a to 15d.

  In this system configuration, the service control units 15a to 15d are provided for each of the service areas 22a to 22d. However, based on the location information output from the mobile terminal location detection unit 14 and the mobile terminal identification information, 1 A single service control unit may be configured to provide a plurality of services or sub-services.

  Next, the configuration of the mobile terminal 13 will be described with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of the mobile terminal.

  As shown in FIG. 2, the mobile terminal 13 described above includes a control unit 31, a beacon signal receiving unit 32, a service identification information specifying unit 33, a service providing database 34, an operation mode information selecting unit 35, and a transmitting unit 36. Is done.

  The control unit 31 sends and receives control signals and data to and from each unit, and controls the entire mobile terminal. The beacon signal receiving unit 32 receives beacon signals transmitted from the beacons 12a to 12d. The service identification information specifying unit 33 analyzes the beacon signal received by the beacon signal receiving unit 32 and specifies the service identification information included in the beacon signal.

  The service providing database 34 stores operation mode information set for each service or sub service. This operation mode information includes, for example, a transmission period, which is a time interval for transmitting a mobile terminal signal from the mobile terminal 13, using a service identification information as a key, a transmission output level when transmitting a mobile terminal signal, a mobile terminal This is information related to an operation mode such as a transmission time for continuously transmitting a signal per cycle. In addition to this, control information necessary for receiving a beacon signal, control information related to display processing, and the like may be stored when the mobile terminal 13 includes a display unit. If the service identification information can be specified, not only the operation mode information in the service but also the operation mode information in the sub service which is an option of the service can be specified. The service is specified, and different sub-services are provided in one service providing area according to authority or the like.

  Note that any number of services or sub-services can be provided depending on the service provision status. When a new service or sub service is added or an existing service or sub service is abolished, the operation mode information stored in the service providing database 34 may be rewritten. For example, the mobile terminal 13 is provided with an input / output unit and removable media so that the service provider can rewrite the operation mode information of the mobile terminal 13 when applying for service, or the operation unit and display on the mobile terminal 13. It is also possible to provide a section so that the operation mode information can be rewritten online. In addition, when the mobile terminal 13 can perform wide-range communication or high-speed communication, operation mode information in a service or sub-service corresponding to the characteristics of the mobile terminal 13 may be written. The operation mode for the sub service is automatically selected by writing a usable mode according to the authority of the user, for example, or arbitrarily selected by the user via the operation unit described above.

  The operation mode information selection unit 35 selects operation mode information corresponding to service identification information included in the beacon signal received by the beacon signal reception unit 32 from the service providing database 34.

  The transmission unit 36 transmits a mobile terminal signal based on the operation mode information selected by the operation mode information selection unit 35 (transmission period of the mobile terminal signal, transmission output level, transmission time, etc.). As a result, even in one location detectable region 21, a mobile terminal signal is transmitted from the mobile terminal 13 in a different operation mode for each service or sub service. If the operation mode information for the service or sub service cannot be acquired from the service providing database 34, the service is not received, and the transmission of the mobile terminal signal is stopped. Further, when the beacon signal receiving unit 35 does not receive the beacon signal for a predetermined time, it does not exist in the service providing area, so the transmission of the mobile terminal signal is stopped.

  As shown in FIG. 1, the position detectable area 21 is provided with a plurality of service providing areas 22a to 22d. For this reason, for example, in a region where the service providing region 22a and the service providing region 22b overlap, the beacon including two different service identification information transmitted from the beacons 12a and 12b by the mobile terminals 13-1 to 13-n. It is necessary to clarify the operation mode of the mobile terminals 13-1 to 13-n at such time.

  Therefore, when the beacon signal reception unit 32 receives a beacon signal including a plurality of different service identification information, the operation mode information selection unit 35 includes service identification information included in the beacon signal having the highest energy among those beacon signals. The transmission unit 36 transmits a mobile terminal signal based on the operation mode information. The operation mode information selection unit 35 identifies the service included in, for example, the beacon signal having the shortest transmission cycle, the beacon signal having the highest transmission output level, the beacon signal having the longest transmission time, etc. from among the plurality of received beacon signals. The operation mode information corresponding to the information is selected. In addition, when the mobile terminal 13-1 to 13-n receives a plurality of different beacon signals, information indicating the operation priority for the operation mode information is stored in the service providing database 34 in advance. The information selection unit 35 may be configured to select an operation mode having the highest operation priority information.

  Next, the configuration of the service control unit 15 will be described with reference to FIG. FIG. 3 is a block diagram illustrating a configuration of the service control unit.

  As shown in FIG. 3, the service control unit 15 described above includes a control unit 41, a location information acquisition unit 42, a service provision processing unit 43, and a beacon signal output unit 44.

  The control unit 41 sends / receives each control signal / data to / from each unit, and controls the entire control unit. The location information acquisition unit 42 acquires location information and mobile terminal identification information detected by the mobile terminal location detection unit 14.

  As described above, the service provision processing unit 43 performs control processing of each device necessary for each service or sub service such as an access control system and a guidance system. The beacon signal output unit 44 generates a beacon signal including service identification information corresponding to each service and outputs the beacon signal to the beacons 12a to 12d.

  Next, a service providing method will be described with reference to FIGS. 4 to 6 are schematic diagrams illustrating a beacon arrangement method in the position detectable region.

  The position information detection area 21 shown in FIG. 4 includes a service providing area 22e that provides an access control system service and a service providing area 22f that provides a guidance system service. For example, the position information detection area 21 is assumed to be in an exhibition hall or an event hall. The service providing area 22e for providing the access control system service is assumed to be an entrance / exit for visitors, and the service providing area 22f for providing the guidance system service is assumed to be an exhibition booth space.

  In the service providing area 22e, entrance gates 51a and 51b are provided in order to determine whether or not a visitor can enter, and four beacons 12e to 12h are provided in the vicinity thereof. A beacon signal including the same service identification information is transmitted from the beacons 12e to 12h, and one service providing area is formed by a plurality of beacons. The same service is provided even in a portion where the beacon signal receivable areas 23e to 23h overlap each other. In particular, in a service performed at the end of the position information detection area 21 such as the service providing area 22e, 12e and 12f among the beacons 12e to 12h for this service may be provided in the peripheral area of the position information detection area 21. Since the service providing area 22f is a guide area, a beacon 12i is provided near the center of the service providing area 22f serving as an exhibition booth space. The area of these two service providing areas 22e and 22f can be determined by changing the output level of the beacon signal transmitted from the beacons 12e to 12i. Further, since the beacons 12e to 12h and the beacon 12i are provided in different service providing areas 22e and 22f, beacon signals including different service identification information are transmitted.

  When the person 24 who owns the mobile terminal 13 moves to the beacon signal receivable area 23e near the service providing area 22e where the entrance gates 51a and 51b are provided, the mobile terminal 13 receives a beacon signal transmitted from the beacon 12e. Start receiving. The mobile terminal 13 starts transmitting a mobile terminal signal based on the operation mode information in the service of the access control system. While the person 24 passes through the entrance gates 51a and 51b, the mobile terminal 13 receives the beacon signals sequentially from the beacons 12e to 12h, and based on the operation mode information in the service of the access control system, the mobile terminal Continue to send the machine signal. If the beacon signal transmitted from the beacons 12e to 12h relates to a service including a sub service, the mobile terminal 13 starts transmitting the mobile terminal signal based on the operation mode information in the sub service of the access control system. As described above, the sub service is automatically selected on the mobile terminal 13 side according to the authority of the user, or an arbitrary sub service is selected via the operation unit of the mobile terminal 13 or the like. If the mobile terminal 13 is in an area where the beacon signal receivable areas 23e to 23h and the position detectable area 21 overlap, the mobile terminal position detection unit 14 is based on the mobile terminal signal transmitted from the mobile terminal 13. The position information of the mobile terminal 13 and the mobile terminal identification information are detected.

  The service provision control unit 15 described above includes the person 24 possessed by the mobile terminal 13 in the service provision area 22e based on the position information detected by the mobile terminal position detection unit 14 and the mobile terminal identification information. Occasionally, the passage authority for the person 24 is determined and the doors of the entrance gates 51a and 51b are controlled to be opened and closed. When the person 24 finishes passing through the entrance gates 51a and 51b and there is no mobile terminal 13 in the beacon signal receivable area 23h, the mobile terminal 13 does not receive the beacon signal from the beacon 12h. Stop.

  When the person 24 moves to the beacon signal receivable area 23i including the service providing area 22f which is an exhibition booth space, the mobile terminal 13 receives the beacon signal transmitted from the beacon 12i, and in the service or sub service of the guidance system The mobile terminal signal is transmitted based on the operation mode information. Similar to the beacon signal receivable areas 23e to 23h, the beacon signal receivable area 23i is in the position detectable area 21, so that the mobile terminal position detector 14 generates a mobile terminal signal transmitted from the mobile terminal 13. Based on this, the position information of the mobile terminal 13 and the mobile terminal identification information are detected.

  Based on the location information detected by the mobile terminal location detection unit 14 and the mobile terminal identification information, the service provision control unit 15 detects the visitor information of the person 24 when the person 24 exists in the service provision area 22f. And providing guidance information to the person 24. In addition, if the mobile terminal 13 can determine the type of a visitor such as a company person or a general visitor and provides different sub-services according to the type of the visitor, the visitor can be provided. It is also possible to provide optimal guidance information. When the person 24 no longer exists in the beacon signal receivable area 23i, the mobile terminal 13 stops receiving the beacon signal from the beacon 12i and stops transmitting the mobile terminal signal again.

  Further, the transmission duration is set in the operation mode information stored in the service providing database 34 inside the mobile terminal 13, and for example, the transmission that transmits the mobile terminal signal after moving to the beacon signal receivable area 23i. It is also possible to provide a guidance system service only for the duration. As described above, a plurality of services are provided in one position detection area by arranging a plurality of beacons in the position detection area or its peripheral area and setting the service providing area.

  In the position information detection area 21 shown in FIG. 5, there are a service providing area 22g for providing an access control service and service providing areas 22h and 22i for providing a guide system service. However, since the service providing area 22g where access control is provided has a wider passage width than the service providing area 22e shown in FIG. 4, seven beacons 12j to 12p are provided in the vicinity of the entrance gates 51a and 51b. A beacon signal including the same service identification information is transmitted from the beacons 12j to 12p, and one service providing area is formed by a plurality of beacons. Similar to the service providing area 22e, the service is performed at the end of the position information detection area 21, so that a beacon is provided in each area of the position information detection area 21 and its surrounding area, and these areas are combined to form one service. A providing area is formed. It becomes the structure which provides the same service in the part where beacon signal receivable area | regions 23j-23p overlap.

  The service providing areas 22h and 22i are assumed to be an exhibition booth space having the same contents divided into two.

If the beacon signal receiving unit 32 does not receive a beacon signal (NO in step S102), the elapsed time of the reception process is counted (step S103). If the elapsed time of the reception process has not elapsed (NO in step S104), the process returns to S102 and the reception process is continued until the beacon signal is received. In addition, when the control unit 31 does not receive a beacon signal even after a predetermined time has elapsed (YES in step S104), the control unit 31 outputs an instruction to the transmission unit 36 to stop transmission of the mobile terminal signal ( Step S105).

  The beacon signal receiving unit 32 receives the beacon signal (YES in step S102), and the service identification information specifying unit 33 specifies the service identification information included in the beacon signal (step S106). The control unit 31 instructs the operation mode information selection unit 35 to select, from the service providing database 34, the service corresponding to the service identification information or the operation mode information in the sub-service within this service based on the service identification information. Output (step S107). If the operation mode information to be acquired does not exist in the service providing database 34 (NO in step S108), the control unit 31 outputs an instruction to the transmission unit 36 to stop transmitting the mobile terminal signal. (Step S105).

  In step S108, the control unit 31 has the operation mode information to be acquired in the service providing database 34 (YES in step S108), and the beacon signal receiving unit 32 receives a beacon signal including a plurality of different service identification information. If there is (YES in step S109), the operation mode information selection unit 35 selects only one operation mode information from the operation mode information selected in step S107 based on the operation priority information described above. (Step S110), and further outputs an instruction to transmit the mobile terminal signal at regular time intervals in the operation mode based on the selected operation mode information to the transmitter 36 (step S111). If the beacon signal reception unit 32 has not received a beacon signal including a plurality of different service identification information (NO in step S109), the control unit 31 sets the operation mode information selected in step S107 to the transmission unit 36. An instruction is output to transmit a mobile terminal signal in the operation mode based on the operation mode (step S111).

  After starting the transmission of the mobile terminal signal in step S111 or after stopping the transmission in step S105, the process returns to step S102 and the same processing is repeated at regular time intervals.

  Next, the flow of the position detection process of the mobile terminal 13 in the mobile terminal position detection unit 14 will be described with reference to FIG. FIG. 8 is a flowchart illustrating a flow of position detection processing of the mobile terminal in the mobile terminal position detection unit.

Each time a mobile terminal signal is acquired (YES in step S202), mobile terminal identification information is detected from the mobile terminal signal (step S203), and then location information of the mobile terminal 13 is detected (step S204). . The detected position information and mobile terminal identification information are output to the service control units 15a to 15d (step S205). Returning to step S201, the same processing is repeated at regular time intervals.

(Step S301). At the same time, the control unit 41 outputs an instruction to the position information acquisition unit 42 so as to start acquisition processing of the position information and mobile terminal identification information output from the mobile terminal position detection unit 14 ( Step S302). The position information acquisition unit 42 returns to step S302 and repeats the process until the position information and the mobile terminal identification information are acquired (NO in step S303). When the position information acquisition unit 42 acquires the position information and the mobile terminal identification information (YES in step S303), the control unit 41 instructs the service provision processing unit 43 based on the acquired position information and the mobile terminal identification information. Then, an instruction is output to provide each service or sub-service (step S304). Returning to step S301 again, an instruction is output to output a beacon signal at regular time intervals.
