Abstract

PROBLEM TO BE SOLVED: To provide location information at an inexpensive cost.SOLUTION: In a location information providing system, a plurality of stationary transmitters has a transmitter transmitting a signal, but does not have a reception function receiving a signal from a mobile transmitter, and is provided at a prescribed location within a facility, and the mobile transmitter has the transmitter transmitting the signal, but does not have a reception function receiving a signal from the stationary transmitter, and is held by a positioned person moving within the facility. When receiving the signal from at least one of the stationary transmitter and the mobile transmitter, a terminal transmits identification information on the transmitter and reception information including a reception date/time to a server. Using a combination of reception information on the mobile transmitter in which a reception time is up to date, and reception information on the timewise corresponding stationary transmitter, the server estimates that a location of the stationary transmitter is a location of the mobile transmitter pertaining to the combination, and notifies a user associated with the positioned person holding the mobile transmitter of the location of the estimated mobile transmitter.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a system for providing position information of a person to be measured in a facility, and in particular, to use a stationary transmitter and a mobile terminal that are located in the vicinity of the person to be measured indoors to hold a mobile transmitter. The present invention relates to a system for providing position information of a positioner.

  In recent years, with the improvement of location information measurement technology and the spread of smartphones, services utilizing location information are provided indoors and outdoors (for example, large indoor facilities and underground shopping streets).

  Various position information measurement techniques have been proposed such as using a transmitter such as a beacon and a mobile terminal such as a smartphone in an area where position information is not known by GPS (Global Positioning System) indoors or underground.

  For example, in Patent Document 1, unique identification information that is different from each other from a plurality of beacons in an area is transmitted, and the mobile terminal receives the unique identification information of a nearby beacon and queries the server. The beacon position information corresponding to the identification information is sent to the mobile terminal, the mobile terminal acquires the current location information, accepts the user's destination information, acquires the destination information based on the attribute information of each place in the area, and A route guidance system that searches for a recommended route from a current location to a destination based on the information, the destination information, and the route network information and presents the recommended route is described.

  Many of the indoor position measurement technologies currently proposed measure the position information of the user who operates the mobile terminal and provide useful information such as route guidance to the user as described in Patent Document 1. The user's flow line or the like is acquired as statistical information from the viewpoint of the facility.

  Further, in Patent Document 2, a beacon transmitter emits a beacon with ID information to the surroundings, and a plurality of beacon receivers are distributed in a positioning space with almost equal density. The base station receives beacon information from each beacon receiver, refers to the beacon reception position information table, obtains the position of the beacon receiver of the beacon information transmission source, and is the same as the position of the beacon receiver. A positioning system that calculates the current position of the beacon transmitter based on the ratio of the electric field strength at each beacon receiver for the ID beacon is described.

Japanese Patent Laid-Open No. 2015-200609 JP 2011-17685 A

  However, for example, when visiting a facility (amusement park, shopping center) with a family and acting separately in the facility, a target person (positioned person) for acquiring location information cannot operate a mobile terminal such as a smartphone, or In the case of a child or the like who is enthusiastic about amusement or the like in the facility, the technique of Patent Document 1 cannot know the current position of the person to be measured.

  In addition, a service form for lending a portable terminal capable of transmitting and receiving data to a child or the like who does not have his / her own portable terminal at the time of entering the facility has a large cost burden on the facility side and is not realistic.

  On the other hand, in the technique of Patent Document 2, since the beacon transmitter is lent to a child or the like who does not own his portable terminal, the cost burden can be reduced. However, in the technique of Patent Document 2, it is necessary to install a large number of beacon receivers in the facility in order to receive radio waves from the beacon transmitter. In general, a beacon receiver is more expensive than a dedicated transmission device and consumes more power, so the introduction and operation costs of the beacon receiver are also increased in the technique of Patent Document 2.

  Here, the techniques of Patent Document 1 and Patent Document 2 and other currently proposed indoor position information measurement techniques are also aimed at measuring the position information of the person to be measured with high accuracy, It may be sufficient if the position can be grasped with an error of about 10 meters. For example, when visiting a facility with a family as described above and acting separately in the facility, it is sufficient that the parent can roughly grasp the current position of the child. Also, in facilities consisting of multiple floors, it may be sufficient to know exactly which floor has children. In many cases, a child can be found by going to a place where a parent is presumed to have a child if necessary and looking around.

  Accordingly, an object of the present invention is to provide location information at a low introduction cost and operation cost.

  A typical example of the invention disclosed in the present application is as follows. That is, a position information providing system including a stationary transmitter, a mobile transmitter, a terminal, and a server, wherein the stationary transmitter includes a transmitter that transmits a signal, and the signal from the mobile transmitter The mobile transmitter has a transmitter that transmits a signal and receives a signal from the stationary transmitter. When the terminal receives a signal from at least one of the stationary transmitter and the mobile transmitter, the identification information and reception of the transmitter are received. The reception information including the date and time is transmitted to the server, and the server uses the combination of the reception information of the mobile transmitter whose reception time is the latest and the reception information of the stationary transmitter corresponding to the time. The position of the vessel is the combination Estimated to be the position of a mobile transmitter according to the allowed, the user that is associated with a target positioning who holds the mobile transmitter, and notifies the position of the estimated movement transmitter.

  According to one embodiment of the present invention, position information of a person to be measured can be provided to a user at a low introduction cost and operation cost. Problems, configurations, and effects other than those described above will become apparent from the description of the following embodiments.

To do. Embodiments of the position information providing system of the present invention will be described below with reference to the accompanying drawings.

<Example 1>
FIG. 1 is a schematic diagram showing the overall configuration of a position information providing system (hereinafter referred to as the present system) of a first embodiment.

  This system includes a management server 11, initial registration data 101, stored data 102, a web server 12, a management terminal 13, a public line / wireless LAN 14, a user terminal 15, a stationary transmitter 16, a mobile transmission. The device 17 and the employee terminal 18 are provided, and the location information is provided mainly indoors in the facility where the present system is operated.

  The management server 11 performs various processes and calculations such as obtaining location information in the facility and organizing statistical information. The management server 11 includes initial registration data 101 (map information in the facility, transmitter information, etc.) registered before the start of operation of the system, and accumulated data 102 (employee terminal, stationary transmitter, Mobile transmitter combination information, etc.). The initial registration data 101 and the accumulated data 102 may be stored in an auxiliary storage device in the management server 11 or in an external storage device connected to the management server 11.

  The management server 11 is configured by a computer having a processor, a memory, an auxiliary storage device, and a communication interface.

  Specifically, the processor executes a program stored in the memory. The memory includes a ROM that is a nonvolatile storage device and a RAM that is a volatile storage device. The ROM stores an immutable program (for example, BIOS). The RAM is a high-speed and volatile storage device such as a dynamic random access memory (DRAM), and temporarily stores a program executed by the processor and data used when the program is executed.

  The auxiliary storage device is a large-capacity non-volatile storage device such as a magnetic storage device (HDD) or a flash memory (SSD), and stores a program executed by the processor and data used when the program is executed. That is, the program is read from the auxiliary storage device, loaded into the memory, and executed by the processor.

  The communication interface is a network interface device that controls communication with other devices in accordance with a predetermined protocol (for example, TCP / IP). The management server 11 may be connected to the management terminal 13 via a communication interface.

  A program executed by the processor is provided to the drawing creation system via a removable medium (CD-ROM, flash memory, etc.) or a network, and is stored in an auxiliary storage device which is a non-temporary storage medium. For this reason, the management server 11 may have an interface for reading data from a removable medium.

  The management server is a computer system configured on a single physical computer or a plurality of logically or physically configured computers, and can operate on separate threads on the same computer. It is also possible to operate on a virtual machine constructed on a plurality of physical computer resources.

  The web server 12 is connected to the management server 11 and provides the management terminal 13 and the user terminal 15 with a screen that displays the position of the person to be measured. The web server 12 is configured by a computer having a processor, a memory, an auxiliary storage device, and a communication interface.

  Further, although the management server 11 and the web server 12 are described separately in the drawing, both servers may be mounted on one computer.

  The management terminal 13 has input means such as a keyboard and a touch panel, and output means such as a display device, and is mainly used in the following three scenes. First, the system administrator uses the initial registration data 101 before registering the system. In addition, when a user (user) of this system receives a facility visit, a person in charge of attendance (mobile transmitter lending manager) uses it to register accumulated data 102 such as mobile transmitter information. Furthermore, it is used by the operation manager (monitoring person) to monitor the system operation status during operation of this system. The management terminal 13 is configured by a computer having a processor, a memory, an auxiliary storage device, an input / output interface, and a communication interface.

  As described above, the management terminal 13 in the present embodiment has various roles and is described as one terminal for convenience, but a plurality of management terminals 13 may be provided according to the role.

  In the facility, there are a user terminal 15, a stationary transmitter 16, a mobile transmitter 17, and an employee terminal 18. The user terminal 15 and the employee terminal 18 are communicably connected to the management server 11 and the like via a public line / wireless LAN 14. The public line / wireless LAN 14 is a network that connects each device of the present system, and includes a wired network (wired LAN) and a wireless network (wireless LAN, mobile phone network).

  The user terminal 15 is held by a user (user) of the present system, and displays position information of a positioning person related to the user such as a family on a display device. The user terminal 15 includes a computer having a processor, a memory, an auxiliary storage device, an input / output interface, and a communication interface.

  The stationary transmitters 16 are radio wave transmitters that intermittently transmit radio waves by short-range wireless communication (for example, Bluetooth (registered trademark), ZigBee, WiFi, etc.), and a plurality of the stationary transmitters 16 are installed in the facility. Since the stationary transmitter 16 does not have a radio wave reception function, the stationary transmitter 16 is inexpensive and intermittently transmits radio waves, so that power consumption is small (for example, battery replacement is unnecessary for about one year). For this reason, the introduction cost and the operation cost are low. A WiFi access point installed in the facility may be used as the stationary transmitter 16. The stationary transmitter 16 may be an indoor GPS pseudo satellite device.

  The mobile transmitter 17 is loaned to a person to be measured (such as the user's family) of the system when visiting the facility, and, like the stationary transmitter 16, short-range wireless communication (for example, Bluetooth (registered trademark), ZigBee, Wi-Fi or the like) is a radio wave transmission device that intermittently transmits radio waves and does not have a radio wave reception function, so that the introduction cost and operation cost are low. Since the mobile transmitter 17 may be lent to a positioning person such as a child who moves rapidly, it is preferable that the mobile transmitter 17 is shaped like a badge so as not to be lost and can be attached to the positioning person's clothes.

  Both or one of the stationary transmitter 16 and the mobile transmitter 17 may transmit an acoustic signal (for example, a sound wave in a frequency band higher than the audible frequency band) instead of a radio wave. In this case, the microphone of the employee terminal 18 may receive sound waves transmitted from the stationary transmitter 16 and the mobile transmitter 17.

  As described above, the stationary transmitter 16 and the mobile transmitter 17 intermittently transmit a signal including its own identification information. The intensity and frequency (time interval) of the radio wave transmitted by the stationary transmitter 16 may be determined by the arrangement density of the stationary transmitters 16 in the facility and the moving speed of the person to be measured. The intensity and frequency (time interval) of the radio wave transmitted by the mobile transmitter 17 may be the same as the intensity and frequency (time interval) of the radio wave transmitted by the stationary transmitter 16, but are determined by the moving speed of the person to be measured. Also good.

  The employee terminal 18 is a mobile communication terminal (smart phone, tablet, mobile phone, or the like) held by an employee or the like disposed in each place in the facility, and is, for example, a smartphone used as an extension telephone. The employee terminal 18 receives radio waves transmitted from the stationary transmitter 16 and the mobile transmitter 17 by short-range wireless communication (for example, Bluetooth (registered trademark), ZigBee, WiFi, etc.). A predetermined application program is installed in the employee terminal 18, and the information of the stationary transmitter 16 and the mobile transmitter 17 that have received the signal is transmitted to the management server 11 without operating the employee terminal 18 at all. .

  Specifically, the employee terminal 18 includes a computer having a processor, a memory, a storage device, an input / output interface, and a communication interface.

  The processor executes a program stored in the memory. The memory includes a ROM that is a nonvolatile storage device and a RAM that is a volatile storage device. The ROM stores an immutable program (for example, BIOS). The RAM is a high-speed and volatile storage device such as a dynamic random access memory (DRAM), and temporarily stores a program executed by the processor and data used when the program is executed. The storage device is a large-capacity nonvolatile storage device such as a flash memory (SSD), for example, and stores a program executed by the processor and data used when the program is executed. That is, the program is provided to the employee terminal 18 via the network, stored in a storage device that is a non-transitory storage medium, read from the storage device, loaded into the memory, and executed by the processor.

  The input / output interface is configured by a liquid crystal display device or a touch panel, and outputs an execution result of the program in a form that can be visually recognized by the employee, and the employee inputs an instruction. The communication interface is a network interface device that controls communication with other devices in accordance with a predetermined protocol, and performs wireless communication in accordance with, for example, WiFi or LTE standards.

  FIG. 2 is a diagram showing initial registration of in-facility map information and stationary transmitter installation information performed before the start of operation of the present system.

  As shown in FIG. 2A, a system administrator or the like of this system registers the initial registration data 101 of the management server 11 through a GUI operation or the like using the management terminal 13. Initial registration data 101 includes a map information table 21 (FIG. 2B), a stationary transmitter installation table 22 (FIG. 2C), an employee terminal table 31 (FIG. 3B), and a mobile transmitter state table. 41 (FIG. 4B).

  As shown in FIG. 2B, the map information table 21 is a table in which map information in the facility is registered, and includes a map ID 211, map entity data 212, and the like. In the map entity data 212, an image of a facility map or the like (or an address of a place where an image or the like is stored) is registered. When the facility is composed of a plurality of floors, areas, etc., the floor map, area map image data, etc. are registered for each floor, area so as to be uniquely identifiable by the map ID 211.

  As shown in FIG. 2C, the stationary transmitter installation table 22 is a table in which the result of mapping the stationary transmitter 16 arranged in the facility to the map information (each floor map or the like) is registered. It consists of a stationary transmitter ID 221, a map ID 222, coordinates 223, and the like. The stationary transmitter ID may be acquired from the stationary transmitter 16 before installation by a short-range wireless transceiver included in the management terminal 13. Further, the administrator may manually input the identification information displayed on the stationary transmitter 16. The map ID 222 corresponds to the map ID 211 registered in the map information table 21, and indicates map information (floor, area, etc.) where the stationary transmitter is installed. The coordinates 223 are relative plane coordinates of the installation position of the stationary transmitter in the map. The numerical value of the relative coordinate can be defined by a numerical value in meters when the lower left corner of the floor map image or the like is the origin, for example.

  On the stationary transmitter mapping screen 23, as shown in FIG. 2 (D), the GUI operation of the management terminal 13, that is, the point on the map displayed on the screen with the mouse is designated, so that the stationary transmitter is placed on the floor map or the like. The transmitter 16 is mapped. The rectangle in the figure is a section of each store, and is a stationary transmitter 16 to which stars are mapped.

  In a complex shopping mall or the like composed of a large number of stores, when it is sufficient to be able to grasp the position of the person to be measured for each store, it is sufficient to place a stationary transmitter at the center of each store as shown in this figure.

  In addition, it is good to install the stationary transmitter 16 comprehensively in the density which can receive the electromagnetic wave from any stationary transmitter 16 in any place in a facility.

  FIG. 3 is a diagram illustrating initial registration of employee terminals and mobile transmitters that is performed before the start of operation of the system.

  As shown in FIG. 3A, the employee terminal 18 includes a short-range receiver 181 that receives radio waves from transmitters (stationary transmitter 16 and mobile transmitter 17) by short-range wireless communication, a public line / wireless. It includes a remote communication unit 182 that performs wireless remote communication with the management server 11 and the like via the LAN 14, and a position information processing unit 183 that is an application program for this system.

  In the management terminal 13, a list of employees possessing the employee terminal 18 is registered in advance in the employee terminal table 31 in the initial registration data 101. As shown in FIG. 3B, the employee terminal table 31 includes a detection terminal ID 311, a user name 312, a telephone number, and the like.

  When the employee terminal 18 starts an application program installed in advance for this system, the position information processing unit 183 is resident, and the mobile transmitter table 32 and the stationary transmitter table 33 currently registered from the management server 11. To get. The mobile transmitter table 32 includes identification information of the mobile transmitter 17 and is obtained by extracting a part of the mobile transmitter state table 41. The stationary transmitter table 33 includes identification information of the stationary transmitter 16 and is a part of the stationary transmitter installation table 22 extracted. The mobile transmitter table 32 and the stationary transmitter table 33 are used to determine whether the signal received by the employee terminal 18 is from the transmitter of the present system.

  FIG. 4 is a diagram showing mobile transmitter rental registration that is performed when a user (user) of this system receives a facility visit.

  This system assumes that multiple people come to the facility as a group, and one group includes a target person (positioned person) 43 for location information acquisition and a user 44 who is a beneficiary of the location information service. Is included. For example, the measured person 43 is a child or the like, and the user 44 is a parent or the like. The user 44 has a user terminal 15 having a screen for displaying position information.

  At the time of facility visit reception, the measured person 43 is loaned the mobile transmitter 17 from the lending manager (visit reception person in charge) 42. As already described, it is preferable that the mobile transmitter 17 can be attached to clothes or the like of the person to be measured 43.

  As shown in FIG. 4A, the lending manager 42 uses the management terminal 13 when lending the mobile transmitter 17 and sets the mobile transmitter 17 to “lending”. The lending flag 412 in the mobile transmitter state table 41 is set to “Yes”.

  Further, the lending manager 42 sets additional information (gender 413, age 414, etc.) of the positionee 43 in order to record statistical information. The additional information may not be accurate information of the person to be measured 43 but may be input by subjective judgment of the lending manager 42, and the psychological hurdle and personal information leakage risk related to the declaration of personal information can be reduced.

  The user (accompanying person) 44 can acquire the position information of the person to be measured (owner of the mobile transmitter 17) 43 by the mobile transmitter ID 411 described in the mobile transmitter 17. As for the user terminal 15, the mobile transmitter ID 411 is used to manually input the number displayed on the mobile transmitter 17 to the user terminal 15, the user terminal 15 reading the barcode displayed on the mobile transmitter 17, or the user terminal The mobile transmitter ID 411 may be acquired by wireless or infrared communication by bringing 15 and the mobile transmitter 17 close to each other. For example, when the user terminal 15 and the mobile transmitter 17 have the NFC communication function, the user terminal 15 and the mobile transmitter 17 are brought close to each other to access a predetermined web site from the user terminal 15 and register the mobile transmitter ID. can do. Further, when the mobile transmitter 17 is lent, a paper on which the mobile transmitter ID is written may be handed to the user 44.

  Since the mobile transmitter 17 needs to be collected when leaving the facility, it is advisable to deposit a deposit at the time of lending. In addition, a receiver that receives radio waves from the mobile transmitter 17 and issues a warning when the mobile transmitter 17 passes is installed at the exit of the facility, and checks whether the mobile transmitter 17 has been brought home when leaving the facility May be. In addition, the mobile transmitter 17 may be used as an entrance ticket for the facility. In this case, the mobile transmitter 17 may be recovered by providing an opening gate that opens the mobile transmitter 17.

  As shown in FIG. 4B, the mobile transmitter state table 41 includes a mobile transmitter ID 411, a renting flag 412, a gender 413, and an age 414, and manages the mobile transmitter 17 that can be lent to the measured person 43. To do. That is, the lending manager 42 updates the mobile transmitter state table 41 when the mobile transmitter 17 is lent and returned.

  FIG. 5 is a diagram illustrating a situation in which the employee terminal 18 receives radio waves from the stationary transmitter 16 and the mobile transmitter 17 during operation of the system.

  As described above, since the stationary transmitter 16 is installed so that it can receive radio waves from any stationary transmitter 16 at any location in the facility, there is always one employee terminal 18 in the facility. Radio waves are received from the stationary transmitter 16 described above. Further, when the measured person 43 possessing the mobile transmitter 17 approaches the employee 51, the employee terminal 18 receives radio waves from the mobile transmitter 17. When the employee terminal 18 receives a radio wave from the stationary transmitter 16 or the mobile transmitter 17, the employee terminal 18 acquires identification information of each transmitter included in the received signal, and the identification information, received radio wave intensity and reception The date and time are transmitted to the management server 11. The transmission timing of the received identification information to the management server 11 may be determined according to the network load and real-time property, and may be transmitted at a predetermined time interval even at the timing of receiving radio waves from each transmitter. The management server 11 records the identification information and radio wave intensity received from the employee terminal 18 in the accumulated data 102.

  When the employee terminal 18 receives the radio wave from the stationary transmitter 16, the employee terminal 18 generates data to be transmitted to the management server 11 without receiving the radio wave from the mobile transmitter 17.

  Further, when the employee terminal 18 receives the radio wave from the mobile transmitter 17, the position of the employee terminal 18 (that is, the mobile transmitter 17) is paired with the information of the stationary transmitter 16 that has received the radio wave immediately before. Is generated, and data to be transmitted to the management server 11 is generated. The data of the mobile transmitter 17 transmitted from the employee terminal 18 to the management server 11 is at least information related to the received data of the stationary transmitter 16 estimated to be the position of the mobile transmitter 17 (for example, to other data). Link information), as shown in FIG. 10, the identification information of the mobile transmitter 17 and the identification information of the stationary transmitter 16 are associated with one line of data (one entry). It does not have to be.

  When the employee terminal 18 receives the radio wave from the mobile transmitter 17, the employee terminal 18 may generate data to be transmitted to the management server 11 using only the received information of the mobile transmitter 17. In this case, the management server 11 combines the information of the stationary transmitter 16 received at the latest time before the time when the employee terminal 18 received the radio wave from the mobile transmitter 17 with the employee terminal 18. (In other words, the position of the mobile transmitter 17) is estimated. Then, the management server 11 may combine the information of the mobile transmitter 17 and the information of the stationary transmitter 16 that has received the radio wave immediately before and store the information in the accumulated data 102. The management server 11 stores the information of the mobile transmitter 17 and the information of the stationary transmitter 16 separately in the stored data 102, and when the management server 11 receives a search request for the location information of the mobile transmitter 17, The position of the mobile transmitter 17 may be estimated by combining the information of the transmitter 17 and the information of the stationary transmitter 16 that has received the radio wave immediately before.

  Correspondence between the stationary transmitter 16 and the mobile transmitter 17 is based on the information of the stationary transmitter 16 received at the latest time before the time when the radio wave from the mobile transmitter 17 is received, as well as the mobile transmission. The information of the stationary transmitter 16 received at the nearest time before and after the time when the radio wave from the device 17 is received may be combined. Further, when the stationary transmitter 16 and the mobile transmitter 17 are combined, a maximum allowable time difference is provided, and the stationary transmitter 16 and the mobile transmitter 17 are combined within a range not exceeding the maximum allowable time. May be.

  When receiving the position information from each employee terminal 18, the management server 11 stores the position information data in the stored data 102 in the data format shown in FIG. This data format will be described later.

  FIG. 6 is a diagram illustrating a situation in which the user terminal 15 requests the management server 11 to search for position information of the positionee during operation of the system.

  When the operation manager (monitoring person) accesses the management server 11 from the management terminal 13, he / she sees a screen displaying the position information of the employee terminal 18 and the mobile transmitter 17 specified based on the position information of the stationary transmitter 16. be able to.

  This process will be described in detail. When the management terminal 13 accesses the web server 12 and inputs a search target range (location, time, etc.), the web server 12 inquires the management server 11 about the search target data, and stores the target data from the stored data 102. To get. Then, the plane coordinates of the stationary transmitter 16 associated with the mobile transmitter 17 to be searched are extracted from the stationary transmitter installation table 22.

  Then, a map including the position of the stationary transmitter 16 is extracted from the map information table 21 of the initial registration data 101, and the plane coordinates of the stationary transmitter 16 are mapped to the map. That is, the position of the stationary transmitter 16 is estimated to be the position of the mobile transmitter 17, and a map in which the position of the stationary transmitter 16 is mapped is created.

  Thereafter, screen data for displaying the created map is transmitted to the management terminal 13. The number of mobile transmitters 17 in each area is displayed by changing the display mode (for example, size and color) of the circle, so that the congestion status of each area and the arrangement of employees can be displayed from a bird's-eye view. can do.

  Moreover, the management terminal 13 may trace and display the position of the specific mobile transmitter 17 by inputting the time zone to be searched. The web server 12 may inquire the management server 11 for data of the mobile transmitter 17 to be searched, acquire the time-series data of the target from the accumulated data 102, and generate screen data to be displayed on the management terminal 13.

  Further, the user terminal 15 can know the position information of the specific mobile transmitter 17 by accessing the management server 11 and inputting the specific mobile transmitter ID 411 obtained at the time of entering the facility. Further, the user terminal 15 may trace and display the position of the mobile transmitter 17 to be searched. The process of generating a screen to be displayed by the user terminal 15 by the web server 12 is to generate a screen to be displayed on the management terminal 13 described above only by limiting the search target range to the mobile transmitter 17 associated with the user. Same as processing.

  Note that the relationship between the user terminal 15 and the mobile transmitter 17 may be registered in the management server 11 and the location information of the mobile transmitter 17 may be push-transmitted to the registered user terminal 15.

  FIG. 7 is a diagram illustrating an example of a screen that displays the search result of the position information of the person to be measured.

  As shown in FIG. 7A, the management terminal 13 displays the position (star) of the employee terminal 18 and the position of the mobile transmitter 17 on a map. The number of mobile transmitters 17 in each area is displayed by changing the display mode (for example, size and color) of the circle, so that the congestion status of each area and the arrangement of employees can be displayed from a bird's-eye view. it can.

  As shown in FIG. 7B, the user terminal 15 displays the position information of the mobile transmitter 17 having the specific mobile transmitter ID 411 on the map. It is advisable to display the time when the signal from the mobile transmitter 17 is received to recognize the freshness of the information.

  Since the mobile transmitter 17 and the employee terminal 18 themselves do not manage position information, the mobile transmitter 17 and the employee terminal 18 need to be associated with the stationary transmitter 16 whose position is specified. This point will be described later.

  FIG. 8 is a diagram illustrating a situation in which the employee terminal 18 receives radio waves from a plurality of stationary transmitters.

  The employee terminal 18 may receive radio waves from a plurality of stationary transmitters 16. In this case, the position information processing unit 183 of the employee terminal 18 compares the strengths of the radio waves from the plurality of stationary transmitters 16 that have received the radio waves, and estimates that the position is close to the stationary transmitter 16 having the highest strength. .

  For example, in the example shown in FIG. 8, when the strength of the signal from the stationary transmitter 16a is −40 dB and the strength of the signal from the stationary transmitter 16b is −60 dB, the employee terminal 18 is close to the stationary transmitter. It can be estimated that it is located.

  FIG. 9 is a diagram illustrating a situation where a plurality of employee terminals 18 have received radio waves from the mobile transmitter 17.

  A plurality of employee terminals 18 may receive radio waves from one mobile transmitter 17. In this case, all employee terminals 18 transmit the information of the mobile transmitter 17 to the management server 11.

  For this reason, the management server 11 collects a plurality of pieces of position information of one mobile transmitter 17 in the same time zone. In this case, since the employee terminals exist in almost the same place, the management server 11 It is better to determine the date and time data as valid values. In this way, the management server 11 accumulates the position information data in the accumulation data 102 shown in FIG.

  FIG. 10 is a diagram showing a format of data stored as the stored data 102 when the position information providing system is operated.

  The location information received from the employee terminal 18 by the management server 11 holds a set of data of a stationary transmitter ID 106 and a mobile transmitter ID 108. Specifically, the location information stored in the accumulated data 102 includes detection date and time 104, employee terminal ID 105, stationary transmitter ID 106, stationary transmitter radio wave intensity 107, mobile transmitter ID 108, and mobile transmitter radio wave intensity 109. . The detection date 104 is the date when the employee terminal 18 received the radio wave from the mobile transmitter 17. The employee terminal ID 105 is identification information of the employee terminal 18 that has received the radio wave from the mobile transmitter 17. The stationary transmitter ID 106 is identification information of the stationary transmitter 16 that has received the radio wave when the employee terminal 18 receives the radio wave from the mobile transmitter 17. The stationary transmitter radio wave intensity 107 is the intensity of the radio wave from the stationary transmitter 16 received by the employee terminal 18. The mobile transmitter ID 108 is identification information of the mobile transmitter 17 that has transmitted the radio wave received by the employee terminal 18. The mobile transmitter radio wave intensity 109 is the radio wave intensity from the mobile transmitter 17 received by the employee terminal 18.

  The mobile transmitter 17 and the employee terminal 18 themselves do not manage location information, and in an indoor facility such as the present embodiment, the location information cannot be acquired by GPS. By holding the position information of the mobile transmitter 17 in pairs, it can be estimated that the current position of the mobile transmitter 17 and the employee terminal 18 is the position of the stationary transmitter 16. Therefore, in this embodiment, the position of the stationary transmitter 16 in the same group is displayed on the map such as the floor map as the position of the mobile transmitter 17 and the employee terminal 18.

  Looking at the accumulated data 102 in time series, the employee terminal 18 with the ID “T-ID001” has the IDs “P-ID1001”, “P-ID1002”, “P-” at the time “10:00:00”. Although the radio waves from the three mobile transmitters 17 having the ID 1003 are received, the employee terminal 18 cannot receive the radio waves from the mobile transmitters 17 one after another, and at time “10:03:00” The radio waves from all mobile transmitters 17 can no longer be received. From this data, it can be seen that each mobile transmitter 17 moves in a direction away from the employee terminal 18 and goes out of the reception area of the employee terminal 18.

  As shown in FIG. 9, when a plurality of employee terminals 18 receive radio waves from one mobile transmitter 17, for example, radio waves from the mobile transmitter 17 with ID “P-ID1003” At 10:00, the employee terminal 18 with ID “T-ID001” received, but at the time “10:03:00”, the employee terminal with ID “T-ID002”. 18 is receiving. Therefore, when the position of the mobile transmitter 17 is displayed after the time “10:03:00”, “S-ID0002” associated with the employee terminal 18 of “T-ID002” received later. It is estimated that the mobile transmitter 17 is at the position of the stationary transmitter 16, and the estimated position is displayed on the map.

  As described above, in the first embodiment, the low cost introduction is achieved by three devices, that is, the stationary transmitter 16 dedicated to transmission, the mobile transmitter 17 dedicated to transmission, and the employee terminal 18 that receives both radio waves. The position information of the measured person 43 can be provided to the user 44 with the cost and the operation cost, and the position information of the measured person 43 can be provided to the user 44 with sufficient accuracy.

  In addition, when the user receives the location information providing service of this embodiment, it is not necessary to install a specific application on his / her mobile terminal, and member registration is not required. Since there is no need to convey information to the service provider, the service can be used easily without worrying about leakage of personal information.

  Further, the web server 12 generates screen data for displaying the estimated position of the mobile transmitter on the map, and the screen data is transmitted to the mobile transmitter 17 located in a predetermined area on the map. Since it displays in the aspect according to the number, the congestion situation of each area, the arrangement | positioning of an employee, etc. can be displayed from a bird's-eye view.

  Further, when the employee terminal 18 receives a signal from the mobile transmitter 17, the received information including the identification information of the mobile transmitter 17 and the reception date and time corresponds to the identification information of the stationary transmitter 16 corresponding in time. In addition, since the information is transmitted to the management server 11, the position information of the person to be measured 43 can be grasped with low introduction costs and operation costs.

<Example 2>
In the first embodiment, the system in which the management server 11 manages the initial registration data 101 and the accumulated data 102 has been described. However, in the second embodiment, the management server 11 is not provided, and each employee terminal 18 receives the initial registration data 101. Have The second embodiment focuses on the viewpoint of notifying the user terminal 15 of the position information of the person to be measured 43, and omits the position trace function and the position statistical processing function of each mobile transmitter 17. Yes.

  FIG. 11 is a schematic diagram showing the overall configuration of the position information providing system of the second embodiment. In the second embodiment, the same configurations and functions as those of the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

  In the position information providing system of the second embodiment, the initial registration data 101 includes a map information table 21, a stationary transmitter installation table 22, and a mobile transmitter table 32, but an employee terminal table 31 and a mobile transmitter state table 41. Not included. That is, in the second embodiment, an employee terminal 18 does not grasp information of other employee terminals 18 and operates independently. The mobile transmitter state table 41 may be managed by the management terminal 13 and may not be distributed to the employee terminal 18. Further, the trace of the position of the mobile transmitter 17 and the accumulated data 102 used for statistical processing are unnecessary.

  In the second embodiment, the management terminal 13 transmits the registered content before the start of operation to each employee terminal 18 via the public line / wireless LAN 14. The employee terminal 18 stores the data distributed from the management terminal 13 as initial registration data 101.

  In addition, when the user (user) visits the facility, the management terminal 13 records the rental registration contents of the mobile transmitter 17 in the mobile transmitter state table 41, and the updated mobile transmitter table 32 is stored in each employee terminal. 18 to send.

  When the employee terminal 18 receives radio waves from both the stationary transmitter 16 and the mobile transmitter 17 during the operation of the position information providing system of the second embodiment, the position information processing unit 183 moves the position of the stationary transmitter 16. It is estimated that it is the position of the transmitter 17 (that is, the measured person 43), and screen data to be displayed on the user terminal 15 in FIG. 7 is created and transmitted to the web server 12 via the public line / wireless LAN 14. . The web server 12 has a screen data storage area for displaying the position information of each mobile transmitter 17. When screen data is received from the employee terminal 18, the screen data is stored in the storage area of the mobile transmitter 17. Write. That is, in the first embodiment, the management server 11 creates a screen to be presented to the user. In the second embodiment, the distributed information processing type in which the position information processing unit 183 of the employee terminal 18 creates a screen to be presented to the user. This is an example.

  When receiving access from the user terminal 15, the web server 12 transmits screen data stored in the storage area of the mobile transmitter 17 to be searched.

  When a plurality of employee terminals 18 receive radio waves from the same mobile transmitter 17, each employee terminal 18 updates screen data in the same storage area of the web server 12. When the page is accessed, the latest position of the measured person 43 is displayed.

  In the second embodiment, the employee terminal 18 transmits information on the stationary transmitter 16 and the mobile transmitter 17 that have received the radio wave to the web server 12, and creates a screen that the web server 12 provides to the user terminal 15. May be. That is, the screen provided to the user terminal 15 may be created by the employee terminal 18 or the web server 12.

  Further, the employee terminal 18 may hold the screen data without holding the screen data provided to the user terminal 15 by the web server 12. In this case, the web server 12 manages a locator (for example, URL of the screen data) indicating the storage location of the screen data for displaying the position of each mobile transmitter 17 and receives access from the user terminal 15. Then, the access from the user terminal 15 is redirected using the locator. Thereby, the user terminal 15 can acquire screen data for displaying the position of the mobile transmitter 17 from the employee terminal 18.

  Furthermore, when the web server 12 does not hold the screen data provided to the user terminal 15 and the employee terminal 18 holds the screen data, when the web server 12 receives access from the user terminal 15, the user terminal 15 The employee terminal 18 that manages the position information of the mobile transmitter 17 that desires the position information is searched, and the access from the user terminal 15 is redirected to the employee terminal 18. Thereby, the user terminal 15 can acquire screen data for displaying the position of the mobile transmitter 17 from the employee terminal 18.

  In the second embodiment, when the employee terminal 18 receives only the radio wave from the stationary transmitter 16, the position information display screen data is not updated. Therefore, the employee terminal 18 does not transmit the data to the web server 12, and the stationary transmitter When radio waves are received from both 16 and the mobile transmitter 17, position information display screen data to be updated is transmitted to the web server 12.

  FIG. 12 is a flowchart showing processing by the employee terminal 18 of the second embodiment.

  First, the position information processing unit 183 of the employee terminal 18 determines whether a radio wave from any of the mobile transmitters 17 has been received (S101). As described above, since the mobile transmitter 17 transmits radio waves intermittently (at a predetermined time interval), the processing after step S102 is executed at the timing when the radio waves from the mobile transmitter 17 are received.

  Then, the number of stationary transmitters 16 that have received radio waves within the latest predetermined time (for example, the previous one minute) is determined (S102). When there is one stationary transmitter 16 that has received the radio wave, the plane coordinates of the stationary transmitter 16 are extracted from the stationary transmitter installation table 22 of the initial registration data 101 (S103). On the other hand, when receiving radio waves from a plurality of stationary transmitters 16, the plane coordinates of the stationary transmitter 16 having the maximum radio field intensity are taken out from the stationary transmitter installation table 22 (S104).

  Then, a map including the position of the stationary transmitter 16 is extracted from the map information table 21 of the initial registration data 101 (S105), and the plane coordinates of the stationary transmitter 16 are mapped to the map (S106). That is, the position of the stationary transmitter 16 is estimated to be the position of the mobile transmitter 17, and a map in which the position of the stationary transmitter 16 is mapped is created.

  Thereafter, the created map is transmitted to the web server 12, and the storage area of the web server 12 corresponding to the mobile transmitter 17 is updated (S107).

  In the first and second embodiments, an application program is installed in the employee terminal 18 held by the employee of the facility and the position information processing unit 183 is resident. The application program of the unit 183 may be installed to provide the position information of the mobile transmitter 17. Thereby, the capture rate of the person to be measured 43 can be increased. In this case, in order to ensure security, it is preferable that the user terminal 15 cannot view position information related to other users. In addition, the facility side may give some privilege to the user who installed the application. By providing the user terminal 15 with the function of the position information processing unit 183, the mobile transmitter 17 (positioned person 43) can be reliably captured even in a facility where the number of employees is small and the employee terminals 18 are arranged only sparsely.

  Also, if there is no person in the group who can operate a terminal such as a smartphone among the visitors to the facility, a piece of paper with the mobile transmitter ID 411 is given to the user 44 at the time of entry, and the user 44 If you want to know the location, if you show a mobile transmitter ID 411 to a nearby employee, the employee uses his / her employee terminal 18 as the user terminal 15 and uses the mobile transmitter ID 411 to move the mobile transmitter. A service may be provided in which the position of 17 is searched and the user 44 is shown a screen displaying the position of the mobile transmitter holder (positionee) 43. As a result, the location information service can be provided to many users.

  In other words, the user terminal 15 and the employee terminal 18 may play the other role depending on the embodiment.

  Further, a function of receiving a signal from the stationary transmitter 16 and a signal from the mobile transmitter 17 may be shared by a fixedly installed receiving apparatus. For example, a short-range wireless communication receiver and a position information processing unit 183 may be mounted on a WiFi access point installed in a facility.

  As described above, in the second embodiment of the present invention, when the employee terminal 18 receives a signal from the mobile transmitter 17, the position of the stationary transmitter 16 corresponding to the time is changed. Since it is estimated as a position, screen data for displaying the estimated position of the mobile transmitter 17 on the map is generated, and the generated screen data is transmitted to the web server 12. The position information of the positioner 43 can be provided to the user.
