Description

The present invention relates to a position information providing device, a method, and a program, and more particularly to a position information providing device, a method, and a program for providing position information to a mobile terminal owned by a pedestrian.

Conventionally, a technique for measuring the position of a terminal device represented by GPS (Global Positioning System) has been widely used. There is also a need for indoor position measurement of terminal devices.

As a technology to meet this need, a signal from a beacon device that emits radio waves, sound waves, or optical signals at regular intervals is received by a terminal device that measures the position, and the position of the terminal device is measured from the signal strength and arrival time. Technology that does not require the installation of a dedicated radio beacon device by diverting the radio waves of the wireless LAN (Local Area Network) base station used for Internet communication, the terminal device transmits a beacon signal and is known There is a technique for measuring the position of a terminal device by receiving a beacon signal with one or more antennas, microphones, cameras, etc. installed at the above location.

Further, in a car navigation system, there is an autonomous navigation technique using a speed sensor, a gyro sensor, a geomagnetic sensor, or the like, which is used for positioning complementation in a place where GPS positioning is not possible, such as a tunnel. Studies are being made to apply this autonomous navigation technique to pedestrian positioning (see, for example, Non-Patent Document 1).

"Report on the development of firefighting activity support information system in spaces where firefighting activities are difficult (May 13, 2003)", Development project team for firefighting activity support information systems in spaces where firefighting activities are difficult, Fire and Disaster Management Agency, Ministry of Internal Affairs and Communications, http://www.fdma.go.jp/neuter/topics/pdfIdx/150513_1.html, Table of Contents: http://www.fdma.go.jp/html/new/pdf/150513_hou/mokuji.pdf, PP. 28-29 http://www.fdma.go.jp/html/new/pdf/150513_hou/28-29.pdf

However, in the technique of using the beacon device, there is a problem that the installation and operation of the beacon device is costly and the installation location of the beacon device is also required.

Further, in the technique of transmitting a beacon signal from a terminal device, there is a problem that installation and operation of receiving side equipment such as an antenna, a microphone, and a camera are costly.

In addition, in the technology that does not require the installation of a dedicated radio beacon device by diverting the radio waves of the wireless LAN base station used for Internet communication, the installation and operation costs of the beacon device are not required, but positioning is performed. Signals from wireless LAN base stations that are not designed and installed for the purpose cannot form a signal strength distribution suitable for indoor positioning, and there is a problem that it is difficult to realize highly accurate positioning.

Further, the method using the autonomous navigation technology does not require the installation and operation costs of the beacon device, but has a problem that the terminal device requires a gyro sensor, a speed sensor, a geomagnetic sensor and the like.

Consumer mobile terminals such as smartphones (hereinafter, simply referred to as "mobile terminals") that have been widely used in recent years may be provided with a gyro sensor, an acceleration sensor, and a geomagnetic sensor (hereinafter, also referred to as "sensor group"). It has become commonplace. Those skilled in the art can come up with a method of performing indoor positioning by autonomous navigation technology using a group of sensors provided in a mobile terminal.

However, since autonomous navigation including inertial navigation is essentially a means of estimating a relative position from the measurement start position, it is necessary to teach the system the measurement start position and the orientation of the mobile terminal.

If you are a person in the field, when the mobile terminal that performs positioning receives the beacon signal emitted from the beacon device, you can correct the position to the preset position of the beacon device, and you can use it for autonomous navigation. You can think of a way to set it as an initial position.

Also in the system described in Non-Patent Document 1, the initial position is determined at the time of entering and exiting the room of the building by installing the "electronic tag" which is a wireless beacon in the indoor evacuation guide light.

According to this method, the number of beacon devices that need to be installed can be significantly reduced as compared with indoor positioning using only the beacon device, and the cost related to the beacon device can be reduced.

However, when the mobile terminal is used as an autonomous navigation device, the position can be corrected by the above method, but the orientation of the mobile terminal is estimated by the geomagnetic sensor, and the presence of the steel frame, mechanical device, etc. causes the geomagnetic disturbance. In a large building, there is a problem that the orientation of the mobile terminal cannot be sufficiently corrected and the accuracy of position measurement by autonomous navigation becomes low.

Further, there is a problem that more precise positioning than the range in which the mobile terminal can receive the beacon signal from the beacon device becomes impossible in the system.

The present invention has been made in view of the above circumstances, and provides a position information providing device, a method, and a program capable of obtaining position information by a simple method when performing position correction in pedestrian autonomous navigation.

Alternatively, it is integrally provided in the non-contact charging device.

Further, in the position information providing device according to the fourth disclosure, in the position information providing device according to any one of the first to third disclosures, the wireless communication control unit initially initializes the position where the own device is installed. As the position, further control is performed to transmit a message prompting the start of positioning by autonomous navigation to the mobile terminal.

On the other hand, in order to achieve the above object, the position information providing method according to the fifth disclosure is such that when the wireless communication control unit is in close proximity to a mobile terminal having a pedestrian autonomous navigation function, the wireless communication control unit and the mobile terminal Proximity wireless communication is started at, and control is performed to transmit position information indicating the position where the own device is installed to the mobile terminal.

Further, in order to achieve the above object, the program according to the sixth disclosure starts proximity wireless communication with the mobile terminal when a mobile terminal having a pedestrian autonomous navigation function is close to the mobile terminal, and automatically communicates with the mobile terminal. The computer is made to control the transmission of the position information indicating the position where the device is installed to the mobile terminal.

As described above, according to the position information providing device, method, and program according to the present disclosure, position information can be obtained by a simple method when performing position correction in pedestrian autonomous navigation.

In addition, location information can be provided to a mobile terminal that performs autonomous navigation using the proximity wireless communication function. As a result, precise position correction can be performed as compared with the case of using a beacon device having a relatively wide communicable range.

In addition, the user does not explicitly set the position with respect to the mobile terminal, but when the mobile terminal is used for a predetermined purpose (opening / closing of a door, etc.), the mobile terminal is brought close to the mobile terminal.

The sensor group 24 includes an acceleration sensor and a gyro sensor as an example. A geomagnetic sensor may be included. An acceleration sensor is a sensor that measures acceleration. The velocity is derived by integrating the acceleration, and the distance is derived by integrating the velocity. In the present embodiment, as an example, a 3-axis acceleration sensor having 3 detection axes is applied.

The angular velocity is a quantity that represents the speed of rotation of the own device, and the angle of rotation is derived by integrating the angular velocity. The gyro sensor has three detection axes: a pitch angle that represents rotation around the X axis (pitching), a roll angle that represents rotation around the Y axis (rolling), and around the Z axis. There is a Yaw angle that represents the rotation (swing) of. Although a relatively inexpensive vibration type gyro sensor is used as the gyro sensor, an optical laser gyro sensor may be used.

When the autonomous navigation mode is set, the sensor acquisition unit 30 periodically acquires sensor information from each sensor of the sensor group 24 and sends the acquired sensor information to the position estimation unit 32.

The position estimation unit 32 estimates the current position of a user walking indoors, for example, by using the sensor information obtained from the sensor acquisition unit 30. Specifically, the position estimation unit 32 estimates the user's moving distance and traveling direction from sensor information, and cumulatively obtains the current position from past measurement points, a method called dead reckoning for pedestrians. Estimate using. The measurement result of the acceleration sensor is used as an example for the moving distance, and the measurement result of the gyro sensor is used as an example for the traveling direction. The position referred to here represents a position on the map indicated by latitude and longitude.

In both the acceleration sensor and the gyro sensor described above, errors accumulate with the passage of time, so that the estimated position may deviate from the actual position. Therefore, the position estimation unit 32 acquires the position information from the position information providing device 40 via the NFC communication unit 22, and sets the position indicated by the acquired position information as the reference position (or the initial position). At this time, the direction of the gravitational acceleration obtained from the acceleration sensor may be the reference direction (or the initial direction) of the own device.

The output unit 34 displays the current position of the user by adding a mark as the current position, displaying the position coordinates, or the like on the map displayed on the display unit 16 of the display surface of the own device. The user walks to the destination by autonomous navigation while looking at this display.

As an example of the non-volatile storage medium, a CD-ROM, a magneto-optical disk, an HDD, a DVD-ROM, a flash memory, a memory card, or the like is assumed.

The antenna 48 includes a resonance circuit in which resonance capacitors that resonate at a predetermined communication frequency are connected in parallel. The antenna 48 functions as an antenna when the own device performs proximity wireless communication with the mobile terminal 10.
