The control means 5 performs various controls using the position information provided by the position information providing means 4. A specific example of the control performed by the control means 5 will be described later. The position information providing system 1 may include a control means 5.

The power supply means 2 is mounted, for example, on a moving body whose position is detected by the position information acquisition means 3, and continuously supplies power to the position information acquisition means 3 while the mobile body is moving. For example, in a configuration in which the power supply means 2 is configured to supply power by providing a battery in the power supply means 2, the power supply will not be cut off due to battery exhaustion during movement of the movable object. Therefore, the position information acquisition means 3 can constantly obtain the position of the moving body. The power supply means 2 supplies power to the position information acquisition means 3 without charging, for example. The means for supplying power without charging includes, for example, a piezoelectric element. A piezoelectric element converts pressure applied to the piezoelectric element into voltage. By configuring so that pressure is applied to the piezoelectric element while the moving object is moving, the piezoelectric element converts the pressure into voltage and can supply power to the position information acquisition means 3. The power supply means 2 may receive wireless power supply from the outside, for example, and supply power to the position information acquisition means 3. The power supply means 2 may include a storage battery. The power supply means 2 includes, for example, a charging means that can be charged while the mobile body is moving.

The position information acquisition means 3 is mounted, for example, on a moving body whose position is detected by the position information acquisition means 3, and acquires the position of the mobile body.

It is possible to provide a location information providing system having the following characteristics.
Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of a vehicle control system according to the first embodiment of the present invention. A vehicle control system is an example of a position information providing system. The vehicle control system 10 of this embodiment includes a terminal device 20, a base station device 30, and a vehicle control device 40. The vehicle control system 10 of this embodiment is a vehicle control device 40 that supports driving operations of a vehicle such as a car, and is capable of recognizing the presence of moving objects in areas of the surrounding environment of the vehicle that are conventionally blind spots. shall be. In the vehicle control system 10, a plurality of terminal devices 20, a plurality of base station devices 30, and a plurality of vehicle control devices 40 are provided.

The terminal device 20 includes a power supply means 21 , a position information acquisition means 22 , and a transmission means 23 . Each means of the terminal device 20 may be realized by hardware, may be realized by a computer executing a program, or may be realized by a combination of hardware and a computer executing a program. Good too. The position information acquisition means 22 detects the position of the terminal device 20 and acquires the position information of the terminal device 20. The transmitting means 23 transmits the position information acquired by the position information acquiring means 22 to the base station device 30. The power supply means 21 supplies power to the position information acquisition means 22 and the transmission means 23. In this embodiment, an example of a moving object is a person. The terminal device 20 is provided in a person's clothing and/or a person's means of transportation. Therefore, the location information of the terminal device 20 is the location information of a person. Articles worn by a person include, for example, shoes worn by the person. The means of transportation for a person includes a bicycle on which a person rides.

The power supply means 21 includes, for example, a piezoelectric element. A piezoelectric element converts pressure applied to the piezoelectric element into voltage. By configuring so that pressure is applied to the piezoelectric element while a person is moving, the piezoelectric element converts the pressure into voltage and can supply power to the position information acquisition means 22 and the transmission means 23. . Therefore, the power supply means 2 includes, for example, a power generation means capable of generating power while the mobile body is moving. A piezoelectric element is an example of this power generation means. The power supply means 21 may include a storage battery. In this case, the voltage generated by the piezoelectric element can be stored in a storage battery. Therefore, the power supply means 21 includes, for example, a charging means that can be charged while the mobile body is moving. A piezoelectric element and a storage battery are examples of this charging means.

The piezoelectric element constituting the power supply means 21 is placed, for example, in the sole of a shoe that is worn by a person. In this case, when a person walks, pressure is applied to a piezoelectric element placed in the sole of the shoe, and the piezoelectric element converts this pressure into voltage. Therefore, the terminal device 20 can operate the position information acquisition means 22 and the transmission means 23 without performing any other charging when a person wearing shoes in which piezoelectric elements are arranged walks. The piezoelectric element may be placed in articles worn by people other than shoes. The piezoelectric element may be placed in various types of footwear, or may be placed in any wearable item where the piezoelectric element is subjected to pressure due to a person's actions such as walking.

Further, the piezoelectric element constituting the power supply means 21 is placed, for example, on the saddle of a bicycle, which is a means of transportation for people. In this case, when a person moves on a bicycle, pressure is applied to a piezoelectric element located in the saddle, and the piezoelectric element converts this pressure into voltage. Therefore, the terminal device 20 can operate the position information acquisition means 22 and the transmission means 23 without performing other charging when a person moves using the moving means in which the piezoelectric element is arranged. The piezoelectric element may be placed on a bicycle pedal. The piezoelectric element may be placed in a means of transportation for people other than a bicycle. Piezoelectric elements can be placed in any means of transportation where piezoelectric elements are subject to pressure due to the movement of a person, such as wheelchairs, walking aids such as senior cars (one-person carts for elderly people), kick skaters, and Segways. It's okay.

As another example of the case where the power supply means 21 has a piezoelectric element, the power supply means 21 may have a power reception section that receives wireless power supply from the outside, for example. The power supply means 21 may include both a piezoelectric element and a power reception unit that receives wireless power supply. Wireless power transfer is a technology that transmits power from a power transmitting device to a power receiving unit using, for example, electromagnetic induction.Recently, it has become possible for the power transmitting device to be separated from the power receiving unit by several meters to receive power at the power receiving unit. Therefore, in this embodiment, the power transmission device is arranged at a position where power can be transmitted to the power supply means 21. A plurality of power transmission devices may be arranged so as to cover the movement range of a person. The power receiving unit receives power from the power transmitting device.

By configuring the power receiving unit to receive power from the power transmitting device while a person, who is a moving object, is moving, it is possible to supply power to the position information acquisition means 22 and the transmitting means 23. Therefore, the power supply means 21 includes, for example, a power receiving means capable of receiving power while the mobile object is moving. The power receiving unit is an example of this power receiving means. The power supply means 21 may include a storage battery. In this case, the power received by the power receiving unit can be stored in the storage battery. Therefore, the power supply means 21 includes, for example, a charging means that can be charged while the mobile body is moving. The power receiving unit and the storage battery are examples of this charging means. The power receiving unit constituting the power supply means 21 is arranged in the above-mentioned person's wearables and/or the person's means of transportation.

The position information acquisition means 22 has a GPS receiver. The position information acquisition means 22 acquires the position of the terminal device 20 using a GPS receiver. The position information acquisition means 22 may acquire the position of the terminal device 20 by other means. The position information acquisition means 22 may widen the range in which the position can be acquired by acquiring the position of the terminal device 20 using a plurality of means. The location information is, for example, information including the latitude and longitude of the location of the terminal device 20. The position information may be, for example, information indicating the position of the terminal device 20 based on a relative position from a reference position.

The transmitting means 23 transmits the position information acquired by the position information acquiring means 22 to the base station device 30. In this embodiment, communication between the terminal device 20 and the base station device 30 and communication between the base station device 30 and the vehicle control device 40 are performed using a fifth generation mobile communication system (hereinafter referred to as "5G"). This is done using a typical communication system that is ultra-high speed, ultra-low latency, and can connect many people at the same time. This makes it possible to respond to higher speed and larger capacity communications, achieve low latency, and make it possible for the receiving side to use the transmitted position information in real time. Furthermore, by using 5G, it is possible to perform communication with low power consumption, and it is possible to operate the position information acquisition means 22 and the transmission means 23 with the power supplied by the power supply means 21. In order to identify which individual among the plurality of terminal devices 20 in the vehicle control system 10 is the terminal device 20 and to obtain the movement history (history of changes in position) of the terminal device 20 on the receiving side of the position information, the transmitting means 23 is used. Alternatively, the terminal ID that can identify the terminal device 20 may be transmitted together with the location information of the terminal device 20. The transmitting means 23 may not transmit the terminal ID of the terminal device 20, but only the position information of the terminal device 20. Note that the terminal device 20 may be, for example, a smartphone terminal that has ultra-high speed, ultra-low delay, and can be connected to multiple devices simultaneously.

The base station device 30 includes a transmitting means 31, a controlling means 32, and a receiving means 33. Each means of the base station device 30 may be realized by hardware, by a computer executing a program, or by a combination of hardware and a computer executing a program. It's okay. The receiving means 33 receives the position information and terminal ID transmitted by the transmitting means 23 of the terminal device 20. The control means 32 controls the operation of the base station device 30. The transmitting means 31 transmits the position information and terminal ID received by the receiving means 33 to the vehicle control device 40. In this embodiment, the base station device 30 is a 5G base station device. If the range of 5G radio waves is short, a plurality of base station devices 30 may be arranged to cover the range of human activity. Power for operating each means of the base station device 30 may be supplied by any known means.

Vehicle control device 40 includes receiving means 41, control means 42, and position information acquisition means 43. Each means included in the vehicle control device 40 may be realized by hardware, may be realized by a computer executing a program, or may be realized by a combination of hardware and a computer executing a program. It's okay. The receiving means 41 receives the location information and terminal ID transmitted by the transmitting means 31 of the base station device 30. The position information acquisition means 43 detects the position of the vehicle control device 40 and acquires the position information of the vehicle control device 40. Since the position information acquisition means 43 has the same configuration as the position information acquisition means 22, detailed explanation will be omitted. The control means 42 uses the position information (position information of the terminal device 20) and the terminal ID received by the reception means 41, and the position information of the vehicle control device 40 acquired by the position information acquisition means 43, so that the vehicle control device 40 Controls the vehicle equipped with it. For example, in controlling automatic driving of the vehicle, the control means 42 performs control to avoid a collision and stop the vehicle according to the positional relationship between the terminal device 20 and the vehicle control device 40. Power for operating each means of the vehicle control device 40 may be supplied by any known means.

The vehicle 51 has a blind spot area 51a that cannot be detected by a conventional camera or electromagnetic radar. For this reason, conventional cameras and electromagnetic wave radars cannot recognize the people 53 and 54 who are present in the blind spot area 51a, and cannot respond to sudden jumps. On the other hand, according to the vehicle control system 10 of the present embodiment, even when the people 53 and 54 are present in the blind spot area 51a due to the building 52, the vehicle control device 40 acquires the position information of the terminal device 20. It is possible to grasp the positions of the person 53 and the person 54. According to this embodiment, it is possible to recognize the presence of a person in an area that was previously a blind spot, and control such as stopping the vehicle or calling attention can be performed, increasing the probability of preventing accidents. be able to.

For example, when the vehicle control device 40 receives the terminal ID along with the position information of the terminal device 20, the control means 42 calculates the movement history (for example, movement direction and movement speed) for each of the plurality of terminal devices 20. However, the future course may be predicted and control may be performed to stop the vehicle 51 depending on the possibility of collision with the vehicle 51. This control can be performed with high precision by taking advantage of the low latency of 5G communication.

For example, when the vehicle control device 40 receives only the position information of the terminal device 20, the control means 42 controls the driver and/or Control may be performed to emit a warning sound to pedestrians. This control can be performed with high precision by taking advantage of the low latency of 5G communication.
