It is assumed that a position management service for a moving body (for example, a bicycle) is performed using a system as shown in FIG. A mobile device 10 is mounted on each of a large number of mobile units managed by the mobile unit information management center 30. Further, it is assumed that a user who wants to share a mobile object has the wireless information terminal 40. The mobile information management center 30 includes an information management control unit 31 and a data storage unit 32. The mobile information management center 30 is connected to the low-speed wireless base station 60 via the communication network 63 or to the high-speed wireless base station 65 via the communication network 64.

Each mobile device 10 includes a low-speed wireless communication unit 14, an antenna 13, a GPS receiver 12 and a GPS antenna 11, a distance measurement 15, a speed measurement 16, an azimuth meter 17, a generator 18, a charger 19, a battery 20, An alarm 25 is provided. The distance measurement 15 and the speed measurement 16 can count the output waveform pulse of the generator 18 and measure the travel distance and travel speed of the moving body. The compass 17 can detect the traveling direction of the moving body. The generator 18 generates a voltage in synchronization with the rotation of the magnet 21 attached to the wheel of the moving body. The charger 19 charges the battery 20 with the output voltage of the generator 18. The battery 20 supplies power to each part of the mobile device 10.

The GPS receiver 12 receives radio waves arriving from a plurality of GPS satellites 50 via the GPS antenna 11 and detects the current position of the mobile body on which the mobile body device 10 is mounted. The low-speed wireless communication unit 14 and the antenna 13 are provided to notify the mobile body information management center 30 of the position information and the travel history of each mobile body from the mobile device 10. The low-speed wireless communication unit 14 can transmit and receive information to and from the mobile information management center 30.

The mobile body information management center 30 communicates with the low-speed wireless communication unit 14 of each mobile body via the wireless communication line 61 as necessary, and receives position information and a travel history of each mobile body.

The mobile body information management center 30 records and manages the information on the storage location of the mobile body based on the positional information of the mobile body received from each mobile body and the travel history of the mobile body.

A wireless information terminal 40 used by a user to use a mobile sharing service includes a wireless communication unit 41, a control unit 42, an operation unit 44, a display unit 43, and an antenna 13.

The mobile body information management center 30 transmits the travel history and current position of the mobile body to the wireless information terminal 40 of the user via the wireless communication line 62. Each user can display the traveling history and the current position of the moving object on the display unit 43 from the wireless information terminal 40 owned by the user.

FIG. 2A shows the attachment position of the mobile device 10 and the magnet 21. The mobile device 10 is attached to the inner position of the wheel 24 at the center of the front fork 22. The magnet 21 is attached at a position overlapping the position of the generator 18 on the outer periphery of the spoke 23.

FIG. 2B is an internal configuration diagram of the mobile device 10. While the moving body is traveling, a voltage is generated by the magnet 21 rotating and periodically moving in the vicinity of the power generation coil mounted on the generator 18. The output voltage from the generator 18 charges the battery 20 via the charger 19. Simultaneously, the output waveform pulses from the generator 18 are counted, the traveling speed is calculated by the speed meter 16, the traveling distance is calculated by the distance meter 15, and the positional information received by the GPS receiver 12 and the azimuth information of the direction meter 17. At the same time, the data is transmitted through the low-speed wireless communication unit 14. When the bicycle is illegally used while parked, an abnormal signal from the generator 18 is detected and an alarm 25 is activated to generate a notification.

FIG. 3 shows an operation state of each part of the mobile device. While the mobile body is traveling, the generator operates to generate power, the charger charges the battery, and the distance measurement, speed measurement, and direction sensor operate to perform travel measurement. The GPS reception and the low-speed wireless communication unit are stopped to suppress power consumption. At the time of suspension, the generator, distance measurement, speed measurement, compass and charger are stopped. The GPS reception receives the current position, and the low-speed wireless communication transmits the current position and the travel measurement information. During parking, the generator, distance measurement, speed measurement, compass, charger, GPS reception, and low-speed wireless communication are all stopped. During unauthorized use, the generator operates and stops every time the moving body repeats running and stopping. Similarly, the battery charger is charged and stopped each time it is repeatedly run and stopped. The GPS reception continuously receives the current position. Low-speed wireless communication issues alarms and transmits the current position as needed.

FIG. 4 shows the change in the remaining battery level depending on the operating state of each part of the mobile device. While driving, the remaining battery charge increases mainly through power generation and charging. During the temporary stop, power generation and charging stop and GPS reception and low-speed wireless communication operate to reduce the remaining battery level. During parking, the generator, distance measurement, speed measurement, compass, charger, GPS reception, and low-speed wireless communication are all stopped, so there is no increase or decrease in the remaining battery level. Next, if unauthorized use of a moving object occurs while parking, an alarm is issued immediately after power generation is activated, and the remaining battery level is reduced. Thereafter, GPS reception continuously receives the current position, and low-speed wireless communication transmits the current position, so that the remaining battery capacity is temporarily reduced. However, the remaining battery capacity is repeatedly recovered by power generation and charging by running.

FIG. 5 shows a map display of the wireless information terminal used by the user. When the user is traveling normally, when the moving body is temporarily stopped, the current position of the moving body, the distance traveled, the average speed, and the trajectory of the travel route are displayed on the map. Furthermore, when the speed limit is exceeded or there is a sudden handle while driving, a mark that alerts the user is displayed. When the mobile object is illegally used, the position and time at which the mobile object is paused are sequentially displayed on the map.
