Description

  The present invention relates to a position information acquisition device, a positioning assistance system, a position information acquisition method, and a program.

Conventionally, a device that acquires position information from a GPS (Global Positioning System) and tracks a route at regular intervals or as necessary is known. However, position information cannot always be acquired from the GPS at a necessary timing. . For this reason, as a method of complementing position information that could not be acquired from GPS, a method of performing sequential position identification by autonomous navigation (Dead Reckoning) using an acceleration sensor, a gyro sensor, or the like is known.
However, position identification by long-term (long-distance) autonomous navigation is difficult to maintain high accuracy, and if a long-term stable position information cannot be acquired from GPS, there will be a large discrepancy with the actual position / route, etc. There is a problem of becoming.

  Therefore, as a method of solving the above problem, a position post having a function of a plurality of wireless IC tags that transmit post data indicating its own information is arranged in a place where GPS radio waves are difficult to reach, and the position post post data A method is proposed in which the server detects the position of the terminal device based on the post data even if the position data cannot be obtained by the GPS function by notifying the server of the post data. (For example, refer to Patent Document 1).

JP 2007-87136 A

  However, the method disclosed in Patent Document 1 is required to be always connected to a server on the Internet via a mobile phone network or equivalent communication means.

In addition, it is practically difficult to develop an infrastructure such as a mobile phone network that covers the mountains, and there is a problem that the place of use is limited to a place where the infrastructure is prepared. In addition, since the battery consumption due to GPS radio wave reception is relatively large, there is also a problem that battery consumption increases by receiving radio waves constantly (or intermittently) regardless of the reception status of GPS radio waves. .

  The present invention has been made in view of such a problem, and easily obtains accurate position information without developing a large-scale infrastructure, and suppresses power consumption when obtaining the position information.

FIG. 7 is a flowchart showing the position information acquisition process. FIG. 8 is a diagram illustrating an example of a course (climbing course) for acquiring position information by the position information acquisition process.

  First, the position information transmission process executed by the position information transmitter 2 will be described with reference to FIG. The position information transmission process is a process of transmitting the transmitter installation position information 242 stored in the storage unit 24 of the position information transmitter 2 to the position information acquisition apparatus 1. In the position information transmitter 2, in cooperation with the position information transmission program 241 read out from the storage unit 24 and appropriately expanded in the RAM 22 by using the power supply to the apparatus main body as a trigger via the operation unit 25. The position information transmission process is executed.

First, the CPU 21 determines whether or not a transmission start instruction operation for the transmitter installation position information 242 has been performed based on the operation of the operation unit 25 by the user (step S1).
If it is determined in step S1 that the transmission start instruction operation has not been performed (step S1; NO), the determination process in step S1 is repeated.
On the other hand, when it is determined in step S1 that a transmission start instruction operation has been performed (step S1; YES), the CPU 21 determines whether or not a timeout has occurred (step S2).

If it is determined in step S2 that time-out has occurred (step S2; NO), the process returns to step S1.
On the other hand, when it is determined in step S2 that the time-out has not occurred (step S2; YES), the CPU 21 determines whether or not the communication connection with the position information acquisition device 1 has been completed via the wireless communication unit 23. (Step S3).

If it is determined in step S3 that the communication connection with the position information acquisition apparatus 1 has not been completed (step S3; NO), the process returns to step S2 and the subsequent processing is performed.
On the other hand, when it is determined in step S3 that the communication connection with the position information acquisition apparatus 1 has been completed (step S3; YES), the CPU 21 receives the position information acquisition apparatus that has been connected for communication via the wireless communication unit 23. 1 transmits the transmitter installation position information 242 (step S4), returns to step S1, and repeats the subsequent processing.

  Next, the position information acquisition process executed by the position information acquisition device 1 will be described with reference to FIG. The position information acquisition process is a process of acquiring course position information (route information) when the user climbs a mountain. In the position information acquisition apparatus 1, in cooperation with the position information acquisition program 151 that the CPU 11 reads from the storage unit 15 and appropriately expands in the RAM 12, triggered by power being supplied to the apparatus body via the operation unit 16. The position information acquisition process is executed.

As shown in FIG. 8, the position information acquisition process executed by the position information acquisition apparatus 1 will be described assuming that the user climbs the course R from P0 to P5 in the direction of P0 to P5. However, the present embodiment is not limited to the case where the course R is advanced in the direction from P0 to P5, and can be similarly implemented when the course R is advanced in the direction from P5 to P0.
Here, P0 is a trailhead. The mountain climbing port P0 is a place where the sky is open (for example, a parking lot) and is a place where GPS radio waves can be received stably. P0 to P1 are, for example, forest roads where the sky is open and, like P0, are areas where GPS radio waves can be stably received. For this reason, the transmitter 3 is not installed along the roads P0 to P1. P1 and P2 are, for example, winding roads along steep valleys, etc., and the upper sky is blocked and is an area (difficult positioning area) F1 in which it is difficult to receive GPS radio waves. For this reason, transmitters 3a to 3e are installed along the roads P1 and P2. P2 to P3 are, for example, mountain trails opened in the sky, and are areas where GPS radio waves can be received stably. For this reason, the transmitter 3 is not installed along the roads P2 to P3. P3 to P4 are, for example, forest roads where the sky is blocked, and are areas (difficult positioning areas) F2 in which GPS radio waves are difficult to receive. For this reason, transmitters 3f to 3h are installed along the roads P3 to P4. P4 to P5 are, for example, roads along the ridge opened by the sky, and are areas where GPS radio waves can be stably received. For this reason, the transmitter 3 is not installed along the roads P4 to P5.

First, the CPU 11 starts a communication connection start instruction operation for starting connection of BLE communication with the position information transmitter 2 installed at the mountain climbing port P0 via the wireless communication unit 14 based on the operation of the operation unit 16 by the user. It is determined whether or not has been made (step S11).
If it is determined in step S11 that the communication connection start instruction operation has not been performed (step S11; NO), the determination process in step S11 is repeated.
On the other hand, when it is determined in step S11 that a communication connection start instruction operation has been performed (step S11; YES), the CPU 11 communicates with the position information transmitter 2 installed at the mountain climbing port P0 via the wireless communication unit 14. It is determined whether or not the communication connection has been completed (step S12).

In step S12, when it is determined that the communication connection with the position information transmitter 2 installed at the mountain climbing port P0 is not completed (step S12; NO), the determination process of step S12 is repeated.
On the other hand, when it is determined in step S12 that the communication connection with the location information transmitter 2 installed at the mountain climbing port P0 is completed (step S12; YES), the CPU 11 sends a call via the wireless communication unit 14. The machine installation position information 242 is received (step S13).

Next, the CPU 11 determines whether or not a predetermined time (for example, several minutes) has elapsed since the transmitter installation position information 242 was received (step S14).
If it is determined in step S14 that a predetermined time (for example, several minutes) has elapsed since the transmitter installation position information 242 was received (step S14; YES), the process proceeds to step S17.
On the other hand, when it is determined in step S14 that a predetermined time (for example, several minutes) has not elapsed since the transmitter installation position information 242 was received (step S14; NO), the CPU 11 Then, it is determined whether or not the transmitter information is received from the transmitter 3 (step S15).

If it is determined in step S15 that the transmitter information has not been received from the transmitter 3 (step S15; NO), the process returns to step S14 and the subsequent processing is performed.
On the other hand, in step S15, it is determined that the transmitter information has been received from the transmitter 3 (step S15; YES), the CPU 11 refers to the transmitter installation position information 242 received in step S13, and receives it from the transmitter 3. It is determined whether or not the transmitter information, specifically the UUID value D1, the major value D2, and the minor value D3 are appropriate (step S16).

If it is determined in step S16 that the UUID value D1 received from the transmitter 3 is appropriate (step S16; YES), the process proceeds to step S23.
On the other hand, when it is determined in step S16 that the UUID value D1 or the like received from the transmitter 3 is not appropriate (step S16; NO), the process returns to step S14 and the subsequent processing is performed.

  Next, in step S17, the CPU 11 sets the BLE communication function by the wireless communication unit 14 to an OFF state, and sets the GPS positioning function by the positioning unit 13 to an ON state (step S17). As shown in FIG. 8, a predetermined time elapses without receiving transmitter information from the transmitter 3 (for example, the transmitter 3a) for a few minutes (before arriving at P1) immediately after leaving the mountain climbing port P0. (Step S14; YES), the BLE communication function by the wireless communication unit 14 of the position information acquisition device 1 is set to OFF, while the GPS positioning function by the positioning unit 13 is ON. Set to state.

  Next, the CPU 11 performs GPS positioning by the positioning unit 13 at predetermined intervals, acquires the measured position as the current position, and stores it in a predetermined area of the storage unit 15 (step S18). Then, the CPU 11 refers to the transmitter installation position information 242 received in step S13, and is registered in the transmitter installation position information 242 in the determination area set based on the measured position stored in step S18. It is determined whether any of the installation positions of the transmitters 3 is included (step S19). That is, since the position measured by the positioning unit 13 is obtained by GPS positioning, the size varies depending on the data processing method, but has a certain amount of error (about 10 m to several tens of m). Therefore, for example, a region in consideration of the above error range (for example, a region having a radius of 10 m to 100 m with the measured position as the center) with the measured position as the center is set, and this is determined as the predetermined determination. It is determined whether or not any of the installation positions of the transmitters 3 registered in the transmitter installation position information 242 is included in this determination area. Thereby, when any one of the installation positions of the transmitters 3 registered in the transmitter installation position information 242 is included in the determination area, the measured position is in the vicinity of any of the transmitters 3. If any of the installation positions of the transmitters 3 registered in the transmitter installation position information 242 is not included in the determination area, the measured position is determined by each transmitter. It can be determined that it is not in the vicinity of 3.

If it is determined in step S19 that none of the installation positions of the transmitters 3 is included in the determination area set based on the measured position (step S19; NO), the process returns to step S18 and thereafter. Perform the process. That is, as shown in FIG. 8, GPS positioning by the positioning unit 13 is continuously performed at predetermined intervals on the road from departure from the mountain climbing port P0 to arrival at P1.
On the other hand, when it is determined in step S19 that any one of the installation positions of the transmitters 3 is included in the determination area set based on the measured position (step S19; YES), the CPU 11 The BLE communication function by the wireless communication unit 14 is set to an ON state, and the GPS positioning function by the positioning unit 13 is set to an OFF state (step S20). That is, as shown in FIG. 8, for example, when it is determined that the user has arrived at P1 and the current position (P1) is in the vicinity of the transmitter 3a, the user has entered the difficult positioning area F1. In this case, the CPU 11 sets the BLE communication function by the wireless communication unit 14 to an ON state, and sets the GPS positioning function by the positioning unit 13 to an OFF state.

Next, the CPU 11 determines whether or not transmitter information has been received from the transmitter 3 via the wireless communication unit 14 (step S21).
In step S21, when it is determined that the transmitter information is not received from the transmitter 3 (step S21; NO), the process returns to step S21 and the subsequent processing is performed.
On the other hand, in step S21, it is determined that the transmitter information has been received from the transmitter 3 (step S21; YES), the CPU 11 refers to the transmitter installation position information 242 received in step S13 and receives it from the transmitter 3. It is determined whether or not the transmitter information, specifically, the UUID value D1, the major value D2, and the minor value D3 are appropriate (step S22).

If it is determined in step S22 that the UUID value D1 or the like received from the transmitter 3 is not appropriate (step S22; NO), the process returns to step S21 and the subsequent processing is performed.
On the other hand, when it is determined in step S22 that the UUID value D1 received from the transmitter 3 is appropriate (step S22; YES), the CPU 11 refers to the transmitter installation position information 242 received in step S13. The installation position of the transmitter 3 at the location value D4 that matches the transmitter information received from the transmitter 3 is acquired as the current position, and stored in a predetermined area of the storage unit 15 (step S23).

Next, the CPU 11 refers to the transmitter installation position information 242 received in step S13, and the current position stored in step S23, that is, the installation position of the transmitter 3 is within the group (same difficulty positioning area). It is determined whether or not it is the final installation position of the transmitter 3 in the direction (step S24). Here, CPU11 can determine a user's advancing direction based on the result measured for every predetermined interval on course R, for example, while performing GPS positioning. Further, the minor value D3 in the transmitter information transmitted from each transmitter 3 is a value that sequentially increases when the course R is advanced from P0 to P5. When the CPU 11 determines that the traveling direction is the direction from P0 to P5, when the minor value D3 in the transmitter information transmitted from the transmitter 3 becomes the maximum value in the group, the CPU 11 The installation position of the transmitter 3 is determined to be the installation position of the last transmitter 3 in the group. When the CPU 11 determines that the traveling direction is the direction from P5 to P0, when the minor value D3 in the transmitter information transmitted from the transmitter 3 becomes the minimum value in the group, the CPU 11 The installation position of the transmitter 3 is determined to be the installation position of the last transmitter 3 in the group.
In step S24, when it is determined that the installation position of the transmitter 3 is not the final installation position of the transmitter 3 in the group (the same difficult positioning area) (step S24; NO), the process returns to step S21 and the subsequent processing is performed. Do. That is, as shown in FIG. 8, while the user is moving from P1 to P2, and while each transmitter information is received from the transmitters 3a to 3d via the wireless communication unit 14, the steps are performed. The processes from S21 to S24 are repeated.
On the other hand, when it is determined in step S24 that the installation position of the transmitter 3 is the final installation position of the transmitter 3 in the group (the same difficult positioning area) (step S24; YES), the process returns to step S17 and thereafter. Perform the process. That is, as shown in FIG. 8, when the user moves from P1 to P2 and the transmitter information is received from the transmitter 3e via the wireless communication unit 14, the user moves from the difficult positioning area F1 thereafter. Therefore, the BLE communication function by the wireless communication unit 14 is set to the OFF state, the GPS positioning function by the positioning unit 13 is set to the ON state (step S17), and the user moves from P2 to P3. GPS positioning by the positioning unit 13 is performed during the period. Note that the processing contents during the movement of the user from P3 to P4 are the same as the processing contents during the movement of the user from P1 to P2, and the processing contents during the movement of the user from P4 to P5 are Is the same as the processing content during the movement from P2 to P3, and the description thereof is omitted.

  As described above, according to the present embodiment, the position information acquisition apparatus 1 is installed in the positioning unit 13 that measures the position of the position information acquisition apparatus 1 and the installation area (difficult positioning areas F1, F2) that the user plans to pass. Communication unit (wireless communication unit 14) capable of receiving the identification information (transmitter information) of the transmitter 3 transmitted from the transmitter 3 being installed, and the installation area (difficult positioning areas F1, F2) where the user is scheduled to pass A storage unit 15 that stores the installation position of the transmitter 3 installed in the network and the identification information of the transmitter 3 in association with each other, and a control unit (CPU 11). In addition, the position information acquisition apparatus 1 determines that the position determined based on the position measured by the positioning unit 13 and the installation position of the transmitter 3 stored in the storage unit 15 is the installation position of the transmitter 3. If the position measured by the positioning unit 13 is determined to be near the installation position of the transmitter 3, the operation of the positioning unit 13 is stopped and the communication unit (wireless The communication unit 14) controls to receive the identification information of the transmitter 3 transmitted from the transmitter 3.

Therefore, according to the position information acquisition device 1 of the present embodiment, the positioning unit 13 is based on the position measured by the positioning unit 13 and the installation position of the transmitter 3 stored in the storage unit 15. It is possible to seamlessly perform exclusive switching between positioning by the wireless communication unit 14 and communication by the wireless communication unit 14.
As a result, the current position can be acquired based on the transmitter information transmitted from the plurality of transmitters 3 without the user being aware of having entered the difficult positioning areas F1 and F2. Moreover, since operation | movement of the positioning part 13 is stopped in the difficult positioning area F1, F2, the power consumption by the positioning part 13 can be suppressed.
Therefore, according to the position information acquisition device 1 of the present embodiment, it is possible to easily acquire accurate position information and reduce power consumption when acquiring the position information without providing a large-scale infrastructure. Can do.

Further, according to the present embodiment, when the position information acquisition device 1 receives the identification information of the transmitter 3 from the transmitter 3 by the wireless communication unit 14, the installation position of the transmitter 3 is passed by the user. In the planned installation area (difficult positioning areas F1, F2), it is determined whether or not it is the last installation position of the transmitter 3 in the direction of travel of the user, and the installation position of the transmitter 3 is determined to be passed by the user. When it is determined that it is the last installation position of the transmitter 3 in the installation area, the communication connection of the wireless communication unit 14 is disconnected and positioning by the positioning unit 13 is started.
For this reason, according to the position information acquisition apparatus 1 of the present embodiment, the installation position of the transmitter 3 is the last installation position of the transmitter 3 in the installation area (difficult positioning areas F1, F2) that the user plans to pass through. Even when it is determined that there is, the exclusive switching between the positioning by the positioning unit 13 and the communication by the wireless communication unit 14 can be performed seamlessly.
Accordingly, the position can be acquired based on the GPS positioning of the positioning unit 13 without the user being conscious of having exited from the difficult positioning areas F1 and F2. Further, since communication by the wireless communication unit 14 is automatically disconnected outside the difficult positioning areas F1 and F2, power consumption by the wireless communication unit 14 can be suppressed.
Therefore, according to the position information acquisition device 1 of the present embodiment, it is possible to easily acquire accurate position information and reduce power consumption when acquiring the position information without providing a large-scale infrastructure. Can do.

  In addition, according to the present embodiment, the position information acquisition device 1 is configured so that each transmitter 3 is connected to a plurality of transmitters 3 that are installed in installation areas (difficult positioning areas F1 and F2) that the user plans to pass through.
