Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a configuration of a map display system according to an embodiment of the present invention.

The map display system of the present embodiment is an information processing system for displaying map information of a specific area such as a floor of a shopping center, a competition facility, a concert venue, etc. on a mobile terminal 20 held by a user.

As shown in FIG. 1, the map display system of the present embodiment includes a plurality of BLE (Bluetooth Low Energy) communication devices 10a to 10i arranged in different places such as the floor of the shopping center, and a user (use). It is composed of a mobile terminal 20 which is a terminal device held and moved by a person). Each of the BLE communication devices 10a to 10i is arranged in a specific area after adjusting the location and the radio wave output intensity so as to cover the target area to be displayed as a map.

Each of the BLE communication devices 10a to 10i transmits the position information of its own device to another BLE communication device, and also transmits from the other BLE communication device by BLE communication, which is a communication method that does not require the communication partner to be specified in advance. The received position information is transferred to another BLE communication device.

Here, the BLE communication devices 10a to 10i are interconnected with other adjacent BLE communication devices by BLE communication, which is a low power consumption communication mode of Bluetooth (registered trademark), which is a short-range wireless communication standard. Has been done.

That is, in the map display system shown in FIG. 1, a plurality of BLE communication devices 10a to 10i are meshed by connecting each device by BLE communication, which is a communication method that does not require a communication partner to be specified in advance. (Mesh) The network is configured.

This mesh network technology is a data routing technology between a plurality of nodes, and the mesh network can be used even when a failure such as a failure occurs in some nodes and a part of the route becomes unusable. It is configured to transfer data between nodes using the route of.

In order to construct such a mesh network, it is not necessary to hold information about other devices to be linked between the devices. By simply moving a device with BLE communication function to the range where BLE communication is possible with any device that is building a mesh network, that device will also be included in the mesh network, and others. A mesh network will be configured together with the equipment of.

The BLE communication includes a communication method using an advertising function and a communication method using a profile such as GATT (Generic Attribute).

All communication methods do not need to specify the communication partner in advance, but in the communication method using the advertising function, it is not possible to specify which device is receiving the data transmitted from the own device. It is a communication method that simply transmits data to the surroundings, such as beacon communication. On the other hand, in the communication method using a profile such as GATT, the existence of other devices existing in the vicinity is confirmed, the profile of the other device is acquired, and the device with which the profile is acquired is 1. This is a communication method for transmitting and receiving one-to-one data.

As described above, the BLE communication using the advertising function is easy to process because it is sufficient to simply transfer the data received from the other device regardless of the existence of the other device. On the other hand, in the communication method using a profile such as GATT, the processing is complicated because the existence of other devices is confirmed and communication is performed. However, in the communication method using a profile such as GATT, it is possible to send and receive a certain amount of data, but in the BLE communication using the advertising function, the amount of data that can be sent and received is small.

When the position information including the count value including the count value in which the number of passed BLE communication devices is larger than the count value corresponding to the position information transferred in the past is received, the position information is not transferred to another BLE communication device.

Specifically, when the plurality of BLE communication devices 10a to 10i transfer the position information to another BLE communication device, the count value indicating the number of passed BLE communication devices is stored in a cache memory or the like, and the count value is stored in the cache memory or the like from the own device. When the position information including the count value including the count value in which the number of passed BLE communication devices is larger than the count value corresponding to the position information transferred in the past is received, the position information is not transferred to another BLE communication device. Further, when the plurality of BLE communication devices 10a to 10i receive the position information including the count value in which the number of passed BLE communication devices is smaller than the count value corresponding to the position information previously transferred from the own device, the plurality of BLE communication devices 10a to 10i are saved.

In the present embodiment, the CPU 31 is described as reading and executing a control program stored in the memory 32 or the storage device 33, but an application program that performs such processing is executed via a network such as the Internet. It may be downloaded and provided to the CPU 31.

FIG. 5 is a block diagram showing a functional configuration of the mobile terminal 20 realized by executing the above control program.

As shown in FIG. 5, the mobile terminal 20 of the present embodiment includes a display unit 41, a control unit 42, a BLE transmission / reception unit 43, and an operation reception unit 44.

The operation reception unit 44 receives various operations from the user such as a map display instruction and a route guidance instruction to a specific facility on the displayed map.

The BLE transmission / reception unit 43 transmits / receives data to / from another device via the BLE communication described above.

The control unit 42 generates map information of a specific area using the position information of each of the plurality of BLE communication devices 10a to 10i received from the communicable BLE communication device among the plurality of BLE communication devices 10a to 10i. do.

For example, when the position information is the coordinate information on the two-dimensional plane of the BLE communication devices 10a to 10i, the control unit 42 obtains the map information of the specific area from the coordinate information of each of the plurality of BLE communication devices 10a to 10i. Generate.

Then, the display unit 41 displays the map information generated by the control unit 42 to the user.

Further, when the information received from the communicable BLE communication device among the BLE communication devices 10a to 10i includes the distance information between the two BLE communication devices, the control unit 42 adds the distance information to the generated map information. You may include it. In this case, the display unit 41 displays the map information to be displayed including the distance information.

The control unit 42 may specify a communicable BLE communication device among the plurality of BLE communication devices 10a to 10i, and specify the position of the mobile terminal 20 on the map information.

This transmission device transmits information regarding the type and location of equipment set in a specific area by BLE communication.

Then, the control unit 42 uses the information received from this transmission device to include the type and position of the equipment in the generated map information.

Further, the control unit 42 may search for a route from the position of the mobile terminal 20 to the position of the equipment displayed on the map information, and provide route guidance for the searched route.

Next, an example of a data format transmitted in BLE communication from the BLE communication devices 10a to 10i, the mobile terminal 20, the transmission device installed in the equipment provided in the specific area, and the like will be described with reference to FIG.

As shown in FIG. 6, the data format transmitted in the BLE communication includes, for example, coordinate information such as X coordinate and Y coordinate, attribute information, count value, and information such as inter-cell distance.

Here, the attribute information is composed of, for example, a device type and an identification number. The device type is a BLE communication device for map generation installed to generate map information, or a BLE communication device for equipment for displaying equipment on map information. It is information for distinguishing whether it is a user terminal or a user terminal held by a user such as a mobile terminal 20. Further, the identification number is number information for identifying the device of this position information. The BLE communication devices 10a to 10i shown in FIG. 1 are BLE communication devices for map generation.

Further, the count value is the passing number information indicating the number of passed BLE communication devices, and the cell-to-cell distance is the distance information indicating the distance between the two BLE communication devices.

Next, as an example, an example of data transmitted from the BLE communication device 10a will be described with reference to FIG. 7. Here, the BLE communication devices 10a to 10i will be described as being arranged, for example, as shown in FIG. 8 in a specific area where map information is desired to be generated. Then, in FIG. 8, the BLE communication device 10a is the starting point on the two-dimensional plane, and the positional relationship from the BLE device 10a is set in the other BLE communication devices 10b to 10i by the X coordinate and the Y coordinate. It is assumed that it is.

Further, here, it is assumed that the BLE communication devices 10a to 10i are preset with the information 1011a to 1011i as the identification information for identifying the devices.

Then, among the BLE communication devices 10a to 10i, each cell composed of the four BLE communication devices will be described assuming that one side is 5 m.

In such a case, from the BLE communication device 10a, as shown in FIG. 7, the X coordinate and the Y coordinate are (0, 0), the device type is 00 (BLE communication device for map generation), and the identification number is 1011a. , Data indicating that the count value is 1 and the distance between cells is 5 m is transmitted by BLE communication.

The state in which the position information of the BLE communication device 10a transmitted in this way is transferred in the mesh network configured by the BLE communication devices 10a to 10i will be described with reference to FIGS. 8 to 10. In the following description, for the sake of simplicity, only the processing procedure in which the coordinate information (0, 0) of the BLE communication device 10a is transferred in the mesh network will be described, but in reality, other The coordinate information of the BLE communication devices 10b to 10i of the above is also transferred in the mesh network in the same manner.

First, as shown in FIG. 8, when data whose position information is (0, 0) and whose count value is 1 is transferred from the BLE communication device 10a as described above, the BLE communication device 10b transfers this data. Is received, the count value is incremented (increased), and the data whose position information is (0, 0) and whose count value is 2 is transferred. Then, the BLE communication device 10b receives and transfers data having a count value of 1, and thus stores 1 as a cache value.

Then, as shown in FIG. 9, the data having a count value of 2 transmitted from the BLE communication device 10b is received by the BLE communication devices 10c and 10e. Then, the BLE communication device 10c that has received the data having a count value of 2 increments the count value and transmits the data having a count value of 3. Then, the BLE communication device 10f that has received the data having a count value of 3 increments the count value and transmits the data having a count value of 4.

In FIGS. 9 and 10, only the count value in the transferred data is displayed in the arrow so that the display is not complicated, and the data transfer processing procedure will be described.

Further, the data having a count value of 1 transmitted from the BLE communication device 10a is received by the BLE communication device 10d. Then, the BLE communication device 10d that has received the data having a count value of 1 increments the count value and transmits the data having a count value of 2.

By performing such a transfer process, as shown in FIG. 9, the BLE communication device 10e has data having a count value of 2 and data having a count value of 2, from the BLE communication devices 10b, 10d, and 10f, respectively. , Data with a count value of 4 will be received. However, among these data, the data having the smallest count value, that is, the data having a small number of passing devices is the data having a count value of 2, so the data having a count value of 4 from the BLE communication device 10f is discarded without being transferred.

In the BLE communication device 10e, the smallest count value among the received data is 2, so 2 is stored as the cache value. Therefore, in the BLE communication device 10e, in the future, when the count value is 3 or more, the data whose coordinate information is (0, 0) is discarded without being transferred even if it is received.

By repeating the transfer process as described above in the mesh network, the data whose coordinate information is (0,0) transmitted from the BLE communication device 10a is transmitted to the BLE communication devices 10b to 10i as shown in FIG. Will be transferred sequentially.

Then, the data whose coordinate information is (1, 0) to (2, 2) transmitted from the BLE communication devices 10b to 10i are also transferred in the mesh network by the same processing.

Therefore, when a user holding the mobile terminal 20 enters such a mesh network, the mobile terminal 20 is located at a position consisting of identification numbers and coordinate information of the BLE communication devices 10a to 10i as shown in FIG. Information will be received by BLE communication.

Then, in the mobile terminal 20, as shown in FIG. 11, the control unit 42 generates map information of a specific area using the position information of each of the plurality of BLE communication devices 10a to 10i.

Specifically, the control unit 42 identifies the outer shape of the specific region by arranging the received coordinate information on the two-dimensional surface, grasps the shape of the specific region, and generates map information.

That is, in the map display system of the present invention, when the BLE communication devices are arranged in a grid state, a specific area for which map information is desired to be generated can be displayed in cell units composed of four BLE communication devices. Then, by combining a plurality of these cells, for example, map information having a complicated shape as shown in FIG. 12 is generated. FIG. 12 shows how the generated map information is displayed on the mobile terminal 20. Further, in the display example shown in FIG. 12, the user can grasp the scale of this map by displaying that the length of one side of the cell is 5 m together with the map information. ..

Next, a process for displaying the current position of the mobile terminal 20 on the map information shown in FIG. 12 will be described.

The mobile terminal 20 estimates from which cell of each cell constituting the generated map information it exists in which cell and in which area in that cell it is located from the currently communicable BLE communication device.

As a specific method, first, the radio wave output strength of the BLE communication devices 10a to 10i constituting the mesh network reaches the other BLE communication devices adjacent to each other along the side of each cell, but the other diagonally. Set it so that it does not reach the BLE communication device.

For example, as shown in FIG. 13, explaining using a cell composed of BLE communication devices 10a, 10b, 10d, and 10e, radio waves from the BLE communication device 10a reach the BLE communication devices 10b and 10d, but the BLE communication device. Adjust the radio wave output strength of the BLE communication device 10a so that it does not reach 10e. That is, the output radio wave strength is set so that communication is possible between the BLE communication device 10a and the BLE communication devices 10b and 10d, but communication between the BLE communication device 10a and the BLE communication device 10e is impossible.

Then, when the mobile terminal 20 is present in this cell, it is possible to estimate in which area in the cell the radio wave from which BLE communication device can be received.

FIG. 14 is a diagram showing nine areas in a cell composed of BLE communication devices 10a, 10b, 10d, and 10e. Further, FIG. 15 is a diagram showing an area determination method using a communicable BLE communication device.

For example, as shown in FIGS. 14 and 15, if the radio waves of the BLE communication devices 10a, 10b, 10d, and 10e can be received, it is estimated that the mobile terminal 20 is located in the area A. Further, if the radio waves of the BLE communication devices 10a, 10b, and 10d can be received, but the radio waves of the BLE communication device 10e cannot be received, it is presumed that the mobile terminal 20 is located in the area B.

Since the BLE communication devices 10a to 10i periodically perform transmission by BLE communication using the advertising function, the mobile terminal 20 has a position on the generated map information as shown in FIG. It is displayed whether the own device exists in.

FIG. 16 shows a case where the current position of the mobile terminal 20 is superimposed on the map information as the current position display 51.

In order to improve the accuracy of position estimation, the output radio wave strength of the BLE communication devices 10a to 10i may be weakened to shorten the distance between cells. Alternatively, in order to improve the accuracy of position estimation, a BLE communication device having the same output radio field strength or a BLE communication having a different output radio field strength (for example, the output radio wave strength is 1/2) is located in the center of each side of each cell. By setting the device and increasing the number, the area for dividing each cell may be made finer.

For example, as shown in FIG. 17, a BLE communication device 30a is installed between the BLE communication devices 10a and 10b, a BLE communication device 30b is installed between the BLE communication devices 10a and 10d, and the BLE communication devices 10b and 10e are installed. A BLE communication device 30c is installed between them, and a BLE communication device 30d is installed between the BLE communication devices 10d and 10e. Then, the output radio wave intensity of the BLE communication devices 30a to 30d is set to 1/2 of the BLE communication devices 10a, 10b, 10d, and 10e.

By setting as shown in FIG. 17, the area for dividing the cell is subdivided, and the accuracy of the position estimation in the cell is improved.

It is not necessary for the BLE communication devices 30a to 30d to transfer the position information of the own device on the mesh network, and the radio waves from the BLE communication devices 30a to 30d are used only for position detection in the cell.

Further, a process for displaying the positions of various facilities such as toilets, emergency exits, and nursing facilities on the generated map information will be described.

As described above, for the equipment to be displayed on the map information, a BLE communication device for displaying the equipment is installed separately from the BLE communication devices 10a to 10i for generating the map.

This equipment display BLE communication device detects the position on the map information of the own device by the same method as the position detection method by the mobile terminal 20 described above. Then, the BLE communication device for displaying the equipment transmits the detected position information in the mesh network in association with the identification number indicating the type of the equipment.

The position information indicating the installation position of this equipment is transferred in the mesh network by the same method as the position information of the BLE communication devices 10a to 10i. The position information indicating the equipment position is also expressed as the coordinate information consisting of the X coordinate and the Y coordinate on the two-dimensional plane.

Then, when the mobile terminal 20 generates map information, it receives the position information indicating the equipment position and displays various equipment together on the generated map information.

For example, as shown in FIG. 18, on the map information displayed on the mobile terminal 20, the toilet display 52, the restricted area display 53, and the emergency exit display 54 are displayed together with the current position display 51. In addition, the display of the atrium area and the equipment such as a restaurant may be displayed.

Further, as shown in FIG. 19, the mobile terminal 20 searches for a route from the current position to the destination when the destination is specified on the map information, and provides route guidance using the searched route. The navigation function may be realized. It should be noted that the equipment to be the destination may be searched on the map information so that the searched equipment is displayed conspicuously on the map information, or the searched equipment may be set as the purpose.

Furthermore, by allowing a plurality of mobile terminals existing in the specific area that generated the map information to transmit the position information of each own device by BLE communication and transfer it to the mesh network, which of the map information The degree of congestion may be displayed to indicate whether the area is congested. For example, map information may be generated and displayed in which the degree of mixing is displayed in shades.

Further, in a certain mobile terminal, the position of a specific mobile terminal may be displayed on the map information. FIG. 20 shows a display example when the position display 55 of a specific mobile terminal registered in advance is displayed on the map information in the mobile terminal 20.

For example, the parent sets the child's mobile terminal in advance, and the current position of the child's mobile terminal is displayed as the position display 55, so that the parent grasps the child's current position.

In the above example, an example of expressing as coordinate information consisting of X coordinate and Y coordinate on a two-dimensional plane has been described, but a solid is used by using coordinate information on a three-dimensional solid consisting of X coordinate, Y coordinate, and Z coordinate. You may express a typical map.
