According to the above-mentioned conventional method (a), it becomes difficult to grasp the position in a place (such as a building) where GPS radio waves (signals from satellites) do not reach.

In the above conventional method (b), it takes a lot of time and effort to manage the system by associating the position detection device with the location information.

Further, if the mobile terminal holds information that associates the position detection device with the location on the mobile terminal, the memory storage area of the mobile terminal is squeezed. May increase.

An object of the present invention is to provide a position detection system and the like which can grasp the position of a target person even in a place where GPS radio waves do not reach and can reduce the burden for the position grasping.

The position detection system of this example is a system that is provided at any desired location and that includes one or more transmitters that transmit their IDs through short-range wireless communication and a server device, and that has the following configurations.

Upon reception of the ID from any of the transmitters, any mobile terminal communicates with the server device if the received ID that is the received ID is registered in the intra-terminal database in the mobile terminal. It has a reception ID corresponding unit that acquires predetermined data corresponding to the reception ID from the in-terminal database without any operation, and transmits a predetermined request including the reception ID to the server device if the predetermined data is not registered.

Upon receiving the request, the server device searches the first database based on the reception ID to obtain predetermined data corresponding to the reception ID, and also searches the second database based on the reception ID. It has a request responding unit that obtains predetermined data corresponding to the ID of the transmitter at the prediction point, and a reply unit that returns each predetermined data obtained by the request responding unit to the requesting mobile terminal.

The reception ID corresponding unit of the mobile terminal acquires each predetermined data returned by the reply unit of the server device and registers the acquired predetermined data in the in-terminal database.

According to the position detection system and the like of the present invention, it is possible to grasp the position even when the target person is in a place where GPS radio waves do not reach, and reduce the burden for grasping the position.

It is a system configuration diagram of a position detection system of the present example. It is a figure which shows the flow of a process of the system of FIG. (A) is a point database, (b) is a specific example of a movement history database. (A) is a movement prediction database, (b) is a specific example of a database in a smartphone. It is a figure which shows the detailed process operation example of this system. It is a functional block diagram of this system.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a system configuration diagram of the position detection system of this example.

In the illustrated system, first, short-distance wireless communication transmitters (beacon transmitter 1) are installed in advance in various places. Each beacon transmitter 1 always continues to transmit a beacon signal including an arbitrary ID number that is assigned and stored in advance by the short-range wireless communication. This uses, for example, a mechanism such as Wi-Fi or "Beacon" that uses Bluetooth (registered trademark), but is not limited to this example.

The mobile terminal 2 such as a smartphone has a function of recognizing the ID number by receiving this beacon signal, a function of notifying the server device 10 of the received ID number and the like and making an inquiry. These functions themselves may be the same as the above-mentioned conventional technology.

In the server device 10 (cloud), arbitrary information (for example, address, application data, etc.) relating to the installation location of the beacon transmitter 1 of this ID number is registered in advance in association with each ID number. .. From this, the server device 10 can determine the address corresponding to the ID number notified from the mobile terminal 2, the service to be provided, and the like.

Note that, for example, in the illustrated example, the server device 10 includes a spot database 11, a movement history database 12, a movement prediction database 13, and the like, which will be described later, but the present invention is not limited to these examples.

In FIG. 1, an example of the flow of processing operations of the position detection system of this example is shown as S1 to S8 in the figure. An example of the processing of S1 to S8 is shown in FIG. 2 and will be described below.

FIG. 1 shows a case where three beacon transmitters 1 are installed in an arbitrary area and an arbitrary user carrying the mobile terminal 2 moves in this area. It is assumed here that the ID numbers of the three beacon transmitters 1 are “001”, “002”, and “003”. Furthermore, the installation location of the beacon transmitter 1 with the ID number = '001' is "Point A", the installation location of the beacon transmitter 1 with the ID number = '002' is "Point B", and the beacon with the ID number = '003'. The location where the transmitter 1 is installed is designated as "Point C". The association information between the ID number and the installation location is registered in the spot database 11 of the server device 10 in advance.

In addition, here, the mobile terminal 2 is a smartphone (smartphone) as an example, and may be illustrated and described with a smartphone as an example, and may be referred to as a smartphone 2 or the like.

In FIG. 1, when the user approaches the beacon transmitter 1 at the point A and the beacon of the beacon transmitter 1 can be received by the mobile terminal 2 of the user, the mobile terminal 2 receives the ID number='. 001' will be received and recognized (S1). From this, the portable terminal 2 sends a predetermined request including the ID number='001' to the server device 10 to make an inquiry (S2). However, when the information related to the ID number='001' is already stored in the mobile terminal 2, the inquiry to the server device 10 is not made.

Upon receiving the request, the server device 10 recognizes the information (corresponding address (point A), application data, etc.) associated with the received ID number='001' based on the registration data of the point database 11 ( S3).

Here, the server device 10 may notify the mobile terminal 2 not only of information related to the current position of the user, but also information related to the vicinity thereof and the like. For example, the location where the user will go next may be predicted, and the mobile terminal 2 may also be notified of information related to the predicted movement point. Here, as an example, it is assumed that the movement predicted point is determined to be the above-mentioned “point B”, and the ID number=“002” corresponding to this “point B” is recognized.

For example, this recognizes an expected point to go to next (here, the point B) from the movement prediction group (an example of the movement prediction database 13 described later). Further, the inquiry results are converted into a database (an example is a movement history database 12 described later), and movement prediction groups are automatically generated. Details will be described later.

For the mobile terminal 2, the server device 10 informs the mobile terminal 2 of information related to the ID number of the current position (predetermined information related to the point A) and movement prediction information (ID number='002' and predetermined information related to the point B). Information)) etc. is returned (S4). The predetermined information is, for example, an address or application data for providing a service.

As a result, on the portable terminal 2 side, information provision and application operation according to the current position are performed (S5). Also, the movement prediction information is stored.

Here, as an example, it is assumed that the user then moves to the point B as predicted. As a result, the mobile terminal 2 of the user receives the radio wave from the beacon transmitter 1 installed at the point B and acquires the ID number='002'.

Every time the mobile terminal 2 acquires a new ID number, it first searches the movement prediction information. Then, if the acquired ID number does not exist in the movement prediction information, an inquiry is made to the server device 10. Since this processing is also performed at the time of S2 and there is no movement prediction information, it is assumed that an inquiry is made to the server device 10 at S2.

Here, since the acquired ID number='002' is included in the movement prediction information, the position information (point B) corresponding to this can be recognized, that is, the current position can be known without inquiring to the cloud. As a result, information provision and application operation according to the current position are performed (S6).

Here, in this example, it is assumed that the user has further moved to the point C. As a result, the mobile terminal 2 of the user receives the radio wave from the beacon transmitter 1 installed at the point C and acquires the ID number=“003”. From this, the mobile terminal 2 retrieves the movement prediction information as described above, but this time, the ID number='003' does not exist in the movement prediction information, so an inquiry to the server device 10 is made as in S2. It will be performed (S7).

Subsequent processing operations of the server device 10 are similar to those of S3, S4, etc., and will not be particularly described here (S8).

As described above, in the position detection system of this example, the place (address, etc.) where the short-range wireless communication transmitter such as the beacon transmitter 1 is installed is managed by the cloud (server device 10). The cloud side also manages application data and the like for providing services according to the location for each location.

Note that, for example, the address managed in the cloud is not managed by the smartphone application development maker or the like, but the management company provides the address management service. In this case, the smartphone application developer or the like does not have to manage the address for the ID number of the beacon transmitter 1 or the like (the above service is sufficient).

When the receiver such as the mobile terminal 2 receives the radio wave from the short-range wireless communication transmitter, it recognizes the identification information (ID number or the like) included in the radio wave and makes an inquiry to the cloud to solve the address.

Whenever we make inquiries to the cloud every time, the amount of communication increases, so some of the information managed in the cloud (one example is the above movement prediction information) is transferred to the mobile terminal 2, and the address is used first. Try to resolve. If the address cannot be resolved, contact the cloud. By address resolution, for example, information provision and application operation according to the current position are performed.

In addition, it is not necessary to change the application of the receiver by changing the MAC address of the faulty device to a new device on the cloud even if the short-distance wireless communication transmitter is out of order within the service range of the address management company. .. Even if the radio transmitter is broken and the radio ID number is changed, the data management on the cloud can be changed, so there is no need to modify the smartphone application.

Furthermore, it is also possible to realize more detailed address resolution by using the radio field intensity (“change the address to be resolved from radio field intensity”). This will be described later using an example.

Hereinafter, a more specific description will be given using a specific example of the above database.
FIG. 3A, FIG. 3B, and FIG. 4A are examples of various databases stored and managed by the server device 10. Further, FIG. 4B shows an example of data held by the mobile terminal 2.

As described above, the server device 10 holds and manages various databases such as the spot database 11, the movement history database 12, and the movement prediction database 13 as an example.

FIG. 3A shows a specific example of the spot database 11.
In the illustrated example, the spot database 11 includes data items such as a beacon ID 21, a distance 22, a spot 23, and application control data 24.

The beacon ID 21 is identification data of each beacon transmitter 1 corresponding to the above ID number. The point 23 is information indicating a place (for example, an address), and in the illustrated example, the building name and the position within the building, but the present invention is not limited to this example. In addition, here, an example corresponding to the above-mentioned example of "changing the address to be solved based on the radio field intensity" is shown, so there is a distance 22. That is, in the spot database 11 of this example, spots 23 (addresses and the like) corresponding to the beacon ID 21 and the distance 22 are registered in advance. Further, data related to the application to be executed according to the beacon ID 21 and the distance 22 (for example, coupon, store guide, toilet guide, etc.) is registered in the application control data (application control data) 24 in advance.

The mobile terminal 2 uses the arbitrary application control data 24 to display, for example, a toilet guide on the display. The application control data 24 is, for example, data for realizing a predetermined service (information provision, coupon distribution, etc.) by a predetermined application on the mobile terminal 2 side, and in the above example, for example, toilet guidance. It can be map data or the URL of a site that provides toilet guidance.

In addition, the beacon ID 21 and the distance 22 indicate the detailed current position of the user. That is, not only is it known that the current position of the user of the mobile terminal 2 is near the beacon transmitter 1 having the beacon ID 21, but also how close the user is.

FIG. 3B shows a specific example of the movement history database 12.
In the illustrated example, the movement history database 12 includes data items such as a reception date/time 31, a beacon ID 32, a distance 33, and a smartphone ID 34. Although each of these data items will be described later, the movement history database 12 stores the data transmitted from the mobile terminal 2 in the above S2 and step S12 described below.

FIG. 4A shows a specific example of the movement prediction database 13.
In the illustrated example, the movement prediction database 13 includes data items of beacon ID 41, prediction beacon ID 42, and prediction beacon ID 43.

The beacon ID 41 is a beacon ID of any beacon transmitter 1. The beacon ID of the beacon transmitter 1 at a position where the user of the mobile terminal 2 is considered to have a high possibility of moving next from the position of the beacon transmitter 1 having the beacon ID 41 is the predicted beacon ID 42 and the predicted beacon. It is registered in ID43. Although two predicted beacon IDs are registered in the illustrated example, the present invention is not limited to this example, and one or three or more may be registered.

Although the registered contents of the movement prediction database 13 may be arbitrarily decided in advance by a developer or the like, in order to improve the prediction accuracy, the predicted data ID of the movement history database 12 is used to obtain a predicted beacon ID at any time to predict the movement. The database 13 may be updated. This will be described in detail later.

FIG. 4B shows an example of the in-smartphone database 50 held by the mobile terminal 2.
In the illustrated example, the in-smartphone database 50 includes data items such as a beacon ID 51, a distance 52, a point 53, and application control data 54.

It may be considered that some records of the point database 11 are stored in the in-smartphone database 50, and therefore the data structure itself may be the same as the point database 11. That is, the beacon ID 51, the distance 52, the point 53, and the application control data 54 may be regarded as the same as the beacon ID 21, the distance 22, the point 23, and the application control data 24, and the description thereof will be omitted.

Hereinafter, the operation of the present system described with reference to FIGS. 1 and 2 will be described in more detail with reference to FIG. 5 and the specific examples of FIGS. 3A, 3B, and 4A and 4B. explain.

FIG. 5 is a diagram showing a detailed processing operation example of the present system.
(1) In FIG. 5, first, the mobile terminal 2 owned by an arbitrary user receives a transmission radio wave (beacon) from the arbitrary beacon transmitter 1 (step S11). Here, as described above, a smartphone which is an example of the mobile terminal 2 is shown and is referred to as a smartphone 2. A predetermined application (smartphone application) installed in this smartphone 2 receives and recognizes beacon data. In addition, here, the server device 10 may be illustrated/described as the cloud server 10 or the like.

The characteristics of the beacon allow the smartphone application to know the approximate distance between the beacon transmitter 1 and the smartphone 2. This is because the smartphone 2 knows the intensity (RSSI value, etc.) of the radio wave received by a general existing technique, and therefore the estimated distance can be calculated by the existing calculation method based on the RSSI value, etc. In addition, here, it is assumed that the estimated distance is roughly determined to be a short distance, a medium distance, and a long distance.

The data transmitted by the beacon transmitter 1 is, for example, “AAA0001”. AAAA represents a beacon management company, and 0001 is an example of a beacon ID. AAAA is added so that it can be identified when mixed with another beacon radio wave, and the smartphone application is set to ignore data other than that of the management company AAAA, for example.

(2) If the beacon ID of the beacon is not registered in the in-smartphone database 50, the smartphone 2 that has received the beacon transmits a request including predetermined data to the server device 10 (cloud) ( Step S12). The predetermined data includes, for example, “identification data of beacon transmitter 1, the estimated distance and smartphone ID” and the like. As a specific example, the predetermined data is, for example, “AAA0001Zabc” (*AAAA: beacon company code, 0001: beacon ID, Z: estimated distance (collected into three patterns of long distance, medium distance, short distance), abc: Smartphone ID) etc. The smartphone ID is identification data assigned to each mobile terminal 2 (smartphone 2) in advance.

(3) When the server device 10 receives the transmission data from the smartphone 2, the server device 10 executes the processes of steps S13, S14, and S15 described below based on the reception data.

First, based on the beacon data, the record corresponding to the current position of the holder of the transmission source smartphone 2 is acquired (step S13). The beacon data is, for example, the beacon ID and the estimated distance of the received data, and these are used to search the spot database 11 to obtain the corresponding record. The relevant record here is a record whose beacon ID 21 and distance 22 are the same as the beacon ID and estimated distance of the above beacon data.

As described above, the point 23 is information indicating a place (for example, an address), and here, the point 23 indicating the current position of the owner of the sender smartphone 2 or the like is acquired.

Then, the owner of the transmission source smartphone 2 acquires the beacon ID of the place where the smartphone 2 is likely to go next and the corresponding data (point 23 and application control data 24) (step S14). First, the movement prediction database 13 is searched based on the beacon ID of the beacon data, and the prediction beacon IDs 42 and 43 of the corresponding record are acquired. The corresponding record here is a record whose beacon ID 41 is the same as the beacon ID of the beacon data.

In the process of step S14, subsequently, the spot database 11 is searched to acquire all records whose beacon ID 21 is the same as the acquired predicted beacon ID 42 or 43.

All the records acquired in step S14 are returned to the sender smartphone 2 in the process of step S16 described later.

Then, the beacon data is accumulated, and the accumulated data is used to improve the prediction accuracy (step S15). The beacon data is stored by additionally storing the received data (excluding the beacon company code) in the movement history database 12 as a new record together with the date and time of the reception. That is, the beacon ID, the estimated distance, the smartphone ID, and the reception date and time of the received data are stored in the beacon ID 32, the distance 33, the smartphone ID 34, and the reception date 31 of the new record of the movement history database 12, respectively.

After that, a process of updating the movement prediction database 13 is performed based on the movement history database 12 (step S15), but this processing need not be performed at the time of receiving the transmission data in the above step S12, and may be performed periodically (for 1 hour, for example). Each time, every day at a predetermined time).

This is totaled by the following elements from the movement history database 12, for example.
B) Beacon ID from the same smartphone (user)
(B) A) is divided into a certain fixed period, and the beacon ID accessed next is extracted from an arbitrary beacon ID. Then, a beacon ID (higher-order beacon ID) that has been accessed next most times is extracted for each beacon ID for all users in total.
C) The movement prediction database 13 is created with the higher beacon ID.

For example, first, of all the records in the movement history database 12, all the records whose reception date/time 31 is within the above-mentioned fixed period are arbitrarily extracted. Next, from the extracted record group, all records related to the user are extracted for each user, and this is set as a processing target record group related to the user. For example, each user is sequentially set as a processing target user, and all records having the same smartphone ID 34 as the target user's smartphone ID are extracted from the extracted record group. It should be noted that the smartphone ID indicates the user, and all the smartphone IDs registered in the smartphone ID 34 may be regarded as the processing target users.

Then, the following processing is sequentially performed for each user (smartphone ID) as a processing target. In the example of FIG. 3B, ‘first, the user having the smartphone ID=“abc” is the processing target, and then, the user having the smartphone ID=“hij” is the processing target.

That is, for the processing target user, the beacon ID 32 of the next record is extracted from the beacon IDs 32 of all the records using the “processing target record group related to the user”, and is stored. In other words, for each user (first is'abc'), it is detected which place the user has made from any place. However, if the beacon ID 32 of any record is the same as the beacon ID 32 of the next record, it is not extracted.

By executing the above processing for all the processing target users, a pair of an arbitrary beacon ID and the next beacon ID is accumulated, so by aggregating these, for each beacon ID, the next beacon ID As a result, the beacon ID having the largest number of appearances and the beacon ID having the second largest number of appearances can be found.

From this, an arbitrary beacon ID is registered in the beacon ID 41, the beacon ID that most frequently appears as the next beacon ID with respect to this beacon ID is registered in the predicted beacon ID 42, and the beacon ID that most frequently appears is the second beacon ID. Is registered in the prediction beacon ID 43 to generate/update the movement prediction database 13.

As described above, since the movement prediction database 13 is generated/updated based on the actual behavior records of many users, it is expected that the movement prediction accuracy using such a movement prediction database 13 is improved.

(4) The server device 10 transmits all the records acquired in steps S13 and S14 to the request transmission source smartphone 2 (step S16). From the above, this transmission data includes, for example, the following contents.
(A) Point 23 corresponding to the current position of the owner of the sender smartphone 2 and application control data 24
(B) The ID of the beacon transmitter 1 corresponding to the position where the owner of the sender smartphone 2 is predicted to go next, the corresponding point 23 and the application control data 24

(5) The sender smartphone 2 performs an operation according to the current position by using the point 23 or/and the application control data 24 corresponding to the current position of (4)(a) in the received data (step). S17). For example, the application control data 24 is used to perform application control according to the current position. For example, the in-store information of the current store is displayed on the display of the sender smartphone 2. Alternatively, using the point 23, the place/address of the current position is displayed on the display of the sender smartphone 2.

In addition, the received data (all records acquired in steps S13 and S14, or only data relating to prediction) is newly registered in the in-smartphone database 50. At this time, if there is existing data in the in-smartphone database 50, all the existing data may be deleted and then newly registered.

Thereby, when the beacon is received after the next time, if the beacon is the beacon from the beacon transmitter 1 at the predicted point, application control and the like can be performed without the need to communicate with the server device 10.

In this way, according to the position detection system and the like of the present example, it is possible to grasp the position even when the target person is in a place where GPS radio waves do not reach, and it is possible to reduce the burden for grasping the position.

It should be noted that the server device 10 has a hardware configuration of a general server device (not shown), and has, for example, a CPU, a storage device (a hard disk, a memory, etc.), a communication interface, etc., which are not shown. .. A predetermined application program is stored in advance in the storage device. When the CPU executes this application program, the various processing functions of the server device 10 described above are realized.

The mobile terminal (smartphone) 2 also has a hardware configuration of a general smartphone, and has, for example, a CPU, a storage device (memory, etc.), a communication interface, an input operation unit, a display unit, etc., which are not shown. ing. A predetermined application program is stored in advance in the storage device. The various processing functions of the mobile terminal (smartphone) 2 described above are realized by the CPU executing this application program.

FIG. 6 is a functional block diagram of this system.
The present system is a system including one or more transmitters 60 and server devices 80 which are provided at arbitrary places and which transmit own IDs by short-range wireless communication. Further, the present system uses the mobile terminal 70 owned by an arbitrary user. An example of the transmitter 60 is the beacon transmitter 1, an example of the server device 80 is the server device 10, and an example of the mobile terminal 70 is the mobile terminal 2.

The mobile terminal 70 includes an in-terminal database 71 and a reception ID correspondence unit 72.
When the reception ID corresponding unit 72 receives an ID from any transmitter 60, if the reception ID is registered in the in-terminal database 71, the reception ID corresponding unit 72 receives the ID from the in-terminal database 71 without communicating with the server device 80. Predetermined data corresponding to the ID is acquired, and if not registered, a predetermined request including the received ID is transmitted to the server device 80.

The server device 80 also includes a request handling unit 81, a reply unit 82, a first database 83, and a second database 84.

An example of the first database 83 is the spot database 11 and an example of the second database 84 is the movement prediction database 13, but the example is not limited to these examples.

Upon receiving the request, the request handling unit 81 searches the first database 83 based on the received ID to obtain the predetermined data corresponding to the received ID, and the second database 84 based on the received ID. By searching, the predetermined data corresponding to the ID of the transmitter 60 at the predicted location is acquired.

The reply unit 82 returns each of the predetermined data acquired by the request handling unit 81 to the request-source mobile terminal 70 as reply data.

The reception ID corresponding unit 72 of the mobile terminal 70 acquires the predetermined data corresponding to the reception ID by the reply unit 82, and registers the reply data (all or only data regarding the predicted point) in the in-terminal database 71. ..

For example, the predetermined data is information indicating a place related to the transmitter whose ID is the reception ID (one example is the above point 23), and/or predetermined application control data corresponding to the place (one example is the above point). This is the application control data 24).

Further, for example, the reception ID corresponding unit 72 of the mobile terminal 70 also communicates with the server device 80 when the reception ID matches the ID of the transmitter 60 at the predicted point registered in the intra-terminal database 71. Without acquiring the predetermined data corresponding to the reception ID from the in-terminal database 71.

Further, for example, the predetermined data corresponding to each ID and the distance is registered in the first database 83, and the reception ID corresponding unit 72 obtains the distance from the transmitter 60 and further calculates the distance. Send the above request including. The request handling unit 81 may obtain the predetermined data corresponding to the reception ID and the distance included in the request from the first database 83.

Further, for example, the server device 80 may further include a storage database 85.
Then, for example, the request includes the identification information of the mobile terminal 70 of the transmission source, and the request handling unit 81 of the server device 80 stores the identification information and the reception ID included in the received request. It is additionally recorded in the database 85. Further, it may further include a generation/update unit 86 that generates/updates the second database 84 based on the accumulation database 85.

Further, in the second database 84, for example, the IDs of the transmitters 60 at one or more predicted points are registered in association with the above IDs.
