Also good.

[Constitution]
With reference to FIG. 2, the structural example of the moving body 10 which concerns on this embodiment is demonstrated. In the present embodiment, the moving body 10 includes a battery 11, a control unit 12, a communication unit 13, a determination unit 14, a moving mechanism 15, a position specifying unit 16, and a current position recording unit 17. In addition, the moving body 10 includes a power switch (not shown) that starts supplying power to each part of the moving body 10.

(Battery 11)
When the power switch is turned on, the battery 11 supplies power to the control unit 12, the communication unit 13, the determination unit 14, the moving mechanism 15, and the position specifying unit 16.

  The battery 11 may have a function of measuring the state of the battery 11 (hereinafter referred to as “battery information”). The battery information is, for example, a remaining battery level. Moreover, you may transmit the result to the control part 12 as battery information. The battery 11 may be used for, for example, a miniaturized drone and the like, and may include a single cell or a plurality of cells including a lithium ion battery, a lithium polymer battery, a fuel cell, and the like that are small and light and can be charged.

(Control unit 12)
The control unit 12 controls the battery 11, the communication unit 13, the determination unit 14, the moving mechanism 15, the position specifying unit 16, and the current position recording unit 17. For example, the control unit 12 controls the moving mechanism 15 in response to a communication establishment determination signal (a signal for notifying that communication has been established) from the determination unit 14 described later.

  The control performed by the control unit 12 may be automatically performed by a control program provided in advance in the control unit 12. Moreover, the structure which the mobile body user U transmits a control signal to the mobile body 10 via a controller, and the communication part 13 receives the control signal may be sufficient. The control unit 12 may control each unit of the moving body 10 according to the control signal from the moving body user U, or may perform automatic control by starting up the control program.

(Communication unit 13)
The communication unit 13 includes transmission / reception antennas, and transmits and receives signals under the control of the control unit 12. The communication unit 13 transmits a predetermined transmission signal to the external communication devices 30A to 30C and receives signals from the external communication devices 30A to 30C. When the communication unit 13 receives signals from the external communication devices 30 </ b> A to 30 </ b> C, the communication unit 13 sends a reception signal to the determination unit 14. In addition, the communication unit 13 does not send a signal to the determination unit 14 when the signals from the external communication devices 30A to 30C are not received.

  The predetermined transmission signal transmitted from the communication unit 13 to the external communication devices 30 </ b> A to 30 </ b> C may be, for example, a standard signal recorded in a memory provided in the communication unit 13.

  For communication between the communication unit 13 and the external communication devices 30A to 30C, for example, the communication unit 13 may receive broadcast signals (beacons) transmitted by the external communication devices 30A to 30C at predetermined intervals. The communication unit 13 may use the broadcast signal as a received signal.

  In communication between the communication unit 13 and the external communication devices 30A to 30C, for example, the communication unit 13 transmits an inquiry signal to the external communication devices 30A to 30C at predetermined intervals and receives the inquiry signal. It is good also as receiving the reply signal from 30C. The communication unit 13 may use return signals from the external communication devices 30A to 30C as reception signals.

  The communication unit 13 can also receive a control signal from the controller and transmit it to the control unit 12.

  Moreover, the frequency band in which the transmission / reception antenna included in the communication unit 13 can be transmitted / received can be variable. The receiving antennas may be arranged omnidirectionally so that signals from the external communication devices 30A to 30C and user terminals (for example, the controller, portable terminal, etc .; not shown) can be received from all directions. The transmission antenna may be arranged omnidirectionally so that a transmission signal can be transmitted in all directions.

  Moreover, although the communication part 13 may receive the electric power supply from the battery 11, the communication part 13 may be provided with the battery for exclusive use. The capacity of the battery only needs to be large enough to transmit the predetermined transmission signal for a predetermined period. The battery is preferably a small, lightweight and rechargeable battery.

  Further, the communication unit 13 may have means for notifying the mobile user U that the communication unit 13 has started transmission or that signals from the external communication devices 30A to 30C have been received. For example, a flashlight is provided at a position where the mobile body user U can visually recognize the mobile body 10. This flash light may be blinked according to transmission / reception. Alternatively, a transmission / reception confirmation signal may be transmitted from the communication unit 13 to the controller on the mobile user U side.

(Determination unit 14)
The determination unit 14 receives a reception signal from the communication unit 13.

  When the reception signal is received from the communication unit 13, the determination unit 14 determines that communication between the communication unit 13 and the external communication devices 30A to 30C has been established. The determination unit 14 transmits a communication establishment signal to the control unit 12.

  When the reception signal is not received from the communication unit 13 at a predetermined time, the determination unit 14 determines that communication between the communication unit 13 and the external communication devices 30A to 30C has not been established. The determination unit 14 transmits a communication unestablished signal (a signal for notifying that communication is not established) to the control unit 12.

(Movement mechanism 15)
Under the control of the control unit 12, the moving mechanism 15 moves the moving body 10 integrally. As described above, when the control unit 12 receives a communication unestablished signal from the determination unit 14, the moving mechanism 15 moves the moving body 10 integrally under the control of the control unit 12.

  The moving mechanism 15 uses, for example, a motor (not shown) driven by power supply from the battery 11 as a power source, and obtains buoyancy, thrust, and the like via a member such as a propeller by using rotation of the motor shaft. As long as the movable body 10 is moved in a controllable manner. As long as it is a mechanism that moves the moving body 10 by supplying electric power, other moving mechanisms may be adopted without being limited to the mechanism using the motor as a power source.

  As the moving operation, for example, the control unit 12 may control the moving mechanism 15 so that the moving body 10 is moved up by the moving mechanism 15 and then moved horizontally at a predetermined altitude.

(Position specifying unit 16)
The position specifying unit 16 includes an input unit (not shown), and receives a physical signal (“physical input”) related to the current position of the moving body 10 via the input unit. Examples of the physical input include a temperature / pressure signal and a navigation signal from a global positioning satellite system.

  The temperature / pressure signal indicates, for example, a temperature sensor / pressure sensor measurement value (temperature / pressure corresponding to the altitude (depth) of the moving body 10) provided in the moving body 10.

  The navigation signal from the global positioning satellite system is, for example, a signal (including information related to the signal transmission time and the satellite orbit) transmitted by the satellites constituting the global positioning satellite system (GNSS).

  The position specifying unit 16 analyzes the physical input and specifies the current position.

  The position specifying unit 16 specifies the current position of the moving body 10 when the power switch provided in the moving body 10 is in the input state.

  The position specifying unit 16 records the specified current position in the current position recording unit 17.

  The position specifying unit 16 may specify the current position of the moving body 10 at a predetermined time interval. Further, the position specifying unit 16 may record the current position specified at a predetermined time interval into the current position recording unit 17 at the predetermined time interval. In addition, the position specifying unit 16 receives the control of the control unit 12 so as to record the current position in the current position recording unit 17 before the moving body 10 is started by the moving body user U and before moving. It may be set in advance. By configuring the position specifying unit 16 in this manner, information on the position where the mobile user U exists can be transmitted to the external communication devices 30A to 30C. Therefore, the third party can grasp the position where the mobile user U exists when the information on the position where the mobile user U exists is acquired through the external communication devices 30A to 30C. Note that the current position before the mobile body 10 is started by the mobile body user U and before the mobile body U starts moving is the current position when the mobile body 10 is started by the mobile body user U, for example. Including the current position when the switch is turned on.

  When the control unit 12 receives a communication establishment signal from the determination unit 14, the position specifying unit 16 transmits the specified current position from the communication unit 13 to the external communication devices 30 </ b> A to 30 </ b> C under the control of the control unit 12.

  The current position specified by the position specifying unit 16 may be a depth / altitude along the direction of gravity as a one-dimensional position. Also, the two-dimensional position may be latitude / longitude. Further, the three-dimensional position may be latitude, longitude, depth / altitude. The current position specified by the position specifying unit 16 may be at least one of latitude, longitude, depth, and altitude.

  If the one-dimensional position is specified, for example, a temperature sensor or a pressure sensor (a water pressure gauge / barometer) may be mounted as the position specifying unit 16 and the depth and altitude may be converted and calculated based on the result. Alternatively, an ultrasonic sensor (for example, a vision positioning sensor) or the like may be mounted as the position specifying unit 16 and the distance from the ground surface / the seabed to the moving body 10 may be measured.

  If you want to specify a two-dimensional position or a three-dimensional position, the input unit is equipped with a dedicated antenna that uses, for example, a navigation signal from GNSS (Global Navigation Satellite System) as a physical input to specify the position. The unit 16 may perform independent positioning analysis or the like. The dedicated antenna may also be used as the reception antenna of the communication unit 13. Information such as measurement error obtained accompanying analysis such as single positioning may be evaluated, and for example, altitude values may be replaced with altitude values obtained by other sensors. In addition, for example, a three-axis acceleration sensor is mounted as the input unit, and the position specifying unit 16 obtains a movement trajectory from the movement start point through analysis by inertial navigation, and specifies the current three-dimensional relative position with respect to the movement start point. May be.

(Current position recording unit 17)
The current position recording unit 17 records the current position specified by the position specifying unit 16.

  When the control unit 12 receives a communication establishment signal from the determination unit 14, the position specifying unit 16 reads the current position recorded in the current position recording unit 17 and controls the external communication device from the communication unit 13 under the control of the control unit 12. You may transmit to 30A-30C.

  The current position recording unit 17 may be either a volatile memory or a nonvolatile memory. These memories are desirably low power consumption, small size and light weight.

<Modification>
The configuration described above is merely an example for carrying out the present invention. Therefore, arbitrary modifications (omitted, replacement, addition, etc.) within the scope of the present invention can be made as appropriate. An example of arbitrary modifications will be described below.

  In any of the first to fourth embodiments, the communication unit 13 can perform data communication with the user terminal, and the determination unit 14 uses the mobile unit 10 and the external communication devices 30A to 30C. When it is determined that the communication is established, the control unit 12 can be configured to relay the communication between the user terminal and the external communication devices 30A to 30C.

  Note that the relaying means that the received data from one side is processed or transferred to the other side without being processed.

  In any of the first to fourth embodiments, the control unit 12 may be configured to transmit the determination result of the determination unit 14 to the user terminal of the mobile user U. Is possible. In this modification, the user terminal is a mobile phone.

  In any of the first to fourth embodiments, the control unit 12 controls the moving mechanism 15 after the determination unit 14 determines that communication is established. Thus, the moving body 10 can be moved to the retracted position.

  It should be noted that moving to the retreat position may be landing, stopping, or the like according to the state of the moving body 10. For example, when the mobile unit 10 is a radio controlled helicopter or a drone that moves by flying, the control unit 12 transmits information related to the mobile unit user U to the external communication devices 30A to 30C. The current position is transmitted toward the external communication devices 30A to 30C, and the current position is transmitted toward the external communication devices 30A to 30C, and then moved and landed in the vertical downward direction. Thus, by moving vertically downward, information on the mobile user U is transmitted to the external communication devices 30A to 30C, the current position of the flying object, and the latitude and the position at which the flying object lands. The difference in longitude (position on the horizontal plane) can be reduced. Therefore, for example, when a third party grasps the current position transmitted to the external communication devices 30A to 30C, it is expected that the position where the flying object has landed can be easily estimated. Note that the moving body 10 can be configured to move not only on a flying object but also on land or on the sea.

  Further, when moving, the moving direction may be determined based on the remaining battery level or the strength of the signal received by the communication unit 13 from the external communication devices 30A to 30C. The control unit 12 may control the moving mechanism 15 so that the moving body 10 moves in the determined moving direction.

  Further, when the current position before the moving body 10 is started by the moving body user U and before moving is recorded in the current position recording section 17, the control section 12 moves to the current position. The moving mechanism 15 may be controlled (to return). Further, when the control unit 12 returns to the initial position (the current position before the movement starts after the moving body 10 is activated by the moving body user U), the control unit 12 notifies the moving body user U that the communication is completed. Alternatively, the mobile user U may be notified that information related to the mobile user U has been transmitted to the external communication devices 30A to 30C. This notification may be notification by a display unit (not shown) or an audio output unit. Thereby, when the mobile body user U exists in the present position (position where the mobile body returns) before the mobile body 10 is started by the mobile body user U, the external communication devices 30A to 30C The mobile user U can recognize that communication has been made.

  Further, in any of the first to fourth embodiments, it is also possible to configure so that a radio wave relay point is interposed in communication between the communication unit 13 and the external communication devices 30A to 30C. It is.

A radio relay point corresponds to an example of a site.

That is, in the mobile body 10, the position information storage unit 18 stores position information of a plurality of radio wave relay points that relay radio waves during communication between the communication unit 13 and the external communication devices 30A to 30C. Under the control of the control unit 12, the position information of the plurality of radio relay points is read, and the selection unit 19 is based on the current position specified by the position specifying unit 16 and the position information of the plurality of radio relay points. The distance from the current position to the plurality of radio relay points is obtained for each radio relay point, and the selection unit 19 selects the radio relay point having the shortest distance from the current position among the plurality of radio relay points. Then, the control unit 12 can be configured to control the movement mechanism 15 so as to move to the radio wave relay point selected by the selection unit 19. For this reason, compared with the case where the mobile body 10 has not memorize | stored the positional information on a radio relay point, it can approach the nearest radio relay point from the present position where the mobile body 10 exists.

Further, in any of the first to fourth embodiments, the mobile unit 10 is further configured to have an emergency setting unit for setting the emergency mode (style). Also good. The emergency mode refers to a state in which the mobile body 10 performs a function or operates in response to a case where the mobile user U is in an emergency. For example, the control unit 12 controls the moving mechanism 15 to move from the current position when the determination unit 14 determines that communication has not been established and the moving body 10 is set to the emergency mode. It can be configured as follows. In addition, information related to the mobile user U, more specifically, information indicating that the mobile user U is in an emergency situation is determined by the determination unit 14 and the mobile body 10 is in an emergency state. It is also possible to configure to transmit to the external communication devices 30A to 30C via the communication unit 13 when the situation mode is set. The setting to the emergency mode is performed, for example, by providing a button, switch, or icon for an emergency in the mobile body 10 and pressing or touching the mobile user U. Further, the mobile unit 10 may be activated and set to the emergency mode.

Moreover, it is preferable that the moving body 10 is configured to be portable in any of the first to fourth embodiments.

Considering that the mobile user U carries the mobile body 10 for mountain climbing, hiking, etc., the weight and size of the mobile body 10 are preferably 10 kg or less and 0.004 m ^ 3 (cubic meter) or less, respectively. Furthermore, it is preferable to set it to 5 kg or less and 0.002 m ^ 3 (cubic meter) or less. In addition, even if the mobile body 10 has a weight and size that can be carried, the mobile body 10 that is not normally carried by the mobile user U is not portable.
