[Outline of radio field intensity measurement method]
FIG. 1 is a diagram for explaining the outline of the radio wave intensity measurement system. The radio field intensity measurement system includes a flying device 1, an information management device 2, and a base station 3 of a mobile phone network. A portion filled with a vertical line in FIG. 1 indicates a region where the radio wave intensity included in the communication quality of the mobile phone network is at a high level. A shaded portion in FIG. 1 indicates an area where the radio wave intensity is at a medium level. A portion filled with a horizontal line in FIG. 1 indicates a region where the radio wave intensity is at a low level. The unfilled portion in FIG. 1 indicates an area where radio waves of the mobile phone network do not reach. The mobile phone network is, for example, an LTE line.

  In FIG. 1, it is assumed that the flying device 1 is flying along the flight path acquired from the information management device 2. When the flight position of the aircraft 1 is a communicable position, the flying device 1 receives the radio wave transmitted by the base station 3 of the mobile phone network and measures the intensity of the received radio wave. When the measured radio wave intensity, which is the intensity of the measured radio wave, is smaller than the reference radio wave intensity, the flying device 1 stores the measured radio wave intensity in the storage unit. Then, the flying device 1 outputs the stored measured radio wave intensity to the information management device 2.

The information management device 2 receives the measured radio wave intensity from the plurality of flying devices 1. The information management device 2 stores the received measured radio wave intensity as a reference radio wave intensity in association with communication area information indicating whether communication is possible.
In this way, the radio wave intensity measurement system can generate information indicating the intensity of the radio wave associated with the position.
Hereinafter, the configuration of the flying device 1 will be described in detail.

[Configuration of the flying device 1]
FIG. 2 is a diagram showing the configuration of the flying device. The flying device 1 includes a flight mechanism 11, a communication unit 12, a flight position specifying unit 13, an environment specifying unit 14, a storage unit 18, and a control unit 19. The control unit 19 includes a communication control unit 191, an acquisition unit 192, a flight control unit 193, a measurement unit 194, a storage control unit 195, and an output unit 196.

  The flight mechanism 11 includes a propeller, a motor that rotates the propeller, a rudder, and the like. The flight mechanism 11 can change the flight speed and the flight direction by operating these mechanisms based on the control of the flight control unit 193.

  The communication unit 12 is a wireless communication module that transmits and receives radio waves for communication using a wireless communication line. The communication unit 12 includes a modulator that modulates transmission data input from the communication control unit 191 and a high-frequency unit that transmits the modulated data as a high-frequency signal in an assigned frequency band. In addition, the communication unit 12 includes a demodulator that demodulates a high-frequency signal received by the high-frequency unit. The demodulator inputs the demodulated received data to the communication control unit 191. The wireless communication line is, for example, an LTE line, Wi-Fi (registered trademark), or Bluetooth (registered trademark).

  The flight position specifying unit 13 specifies a flight position that is a position in flight. Specifically, the flight position specifying unit 13 includes, for example, an altimeter, an acceleration sensor, and a GPS (Global Positioning System) receiver. The flight position specifying unit 13 specifies body information for specifying the state of the flying device 1 such as the flight altitude, the flight speed, the inclination, and the flight position of the flying device 1 and notifies the communication control unit 191 of the information. In addition, the flight position specifying unit 13 may notify the flight control unit 193 of the aircraft information.

  The environment specifying unit 14 includes, for example, an anemometer, a pyranometer, a sunshine meter, a rain sensor, and a snow sensor, and specifies a surrounding environment at a position in flight. The environment specifying unit 14 notifies the output unit 196 of the specified surrounding environment. In addition, the environment specifying unit 14 may notify the communication control unit 191 and the flight control unit 193 of the surrounding environment.

  The storage unit 18 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (hard disk drive), and the like. The storage unit 18 may be removable. The storage unit 18 stores a program executed by the control unit 19. The storage unit 18 is used as a work memory of the control unit 19 and temporarily stores, for example, the flight position specified by the flight position specifying unit 13 described later or the surrounding environment information detected by the environment specifying unit 14 described later. . The storage unit 18 stores the measured radio wave intensity based on the control of the storage control unit 195 described later.

The control unit 19 is, for example, a CPU (Central Processing Unit), and by executing a program stored in the storage unit 18, a communication control unit 191, an acquisition unit 192, a flight control unit 193, a measurement unit 194, a storage control unit 195 and an output unit 196.
The communication control unit 191 controls the communication unit 12 to connect to the mobile phone network. The communication control unit 191 receives the flight path on which the flying device 1 flies and notifies the flight control unit 193 of the flight route. In addition, the communication control unit 191 may receive control information transmitted by the control device that controls the flying device 1 and notify the flight control unit 193 of the received control information.

  The acquisition unit 192 acquires communication area information in which position information indicating a position and communication enable / disable information indicating whether the position indicated by the position information is communicable are associated with each other. For example, the acquisition unit 192 acquires communication area information in which position information is associated with reference radio wave intensity based on radio wave intensity measured in the past. The reference radio wave intensity is the radio wave intensity of the base station 3 measured in advance at the position indicated by the position information. The reference radio wave intensity may be associated with the frequency of the radio wave transmitted by the base station. Specifically, the acquisition unit 192 acquires, as communication area information, map information in which the position and the radio wave intensity of the mobile phone network are associated as shown in FIG. The acquisition unit 192 notifies the measurement unit 194 of the acquired communication area information. The acquisition unit 192 notifies the flight control unit 193 of the communication area information.

  The communication area information may be information in which the position and the intensity of the radio wave transmitted by the base station of the mobile phone network are associated with each other at a height equal to or lower than the limit height at which the flying device 1 can fly. The communication area information may include, for example, information indicating positions of buildings, trees, roads, and landmarks. The communication area information may include height information that indicates the height of the structure, and the height information may be associated with obstacle information that indicates that the flying device 1 will be flying. The communication area information may include information indicating a flight prohibited area where the flight of the flying device 1 is prohibited. The flight prohibition area is, for example, an airspace around an airport, an airspace having a height of 150 m or more from the surface of the water or the ground, and a population concentration area. Further, the communication area information may be communication enable / disable information corresponding to the height input when the user searches or sets the flight route in the information management device 2, for example.

  The communication area information may be different for each height from the ground. Specifically, for example, the communication area information at a height of 10 m from the ground may be different from the communication area information at a height of 20 m from the ground. The acquisition unit 192 may acquire communication area information at a height from the ground recommended for the aircraft to fly based on the aircraft information of the aircraft.

  The acquisition unit 192 may acquire a plurality of pieces of radio wave intensity information associated with a plurality of frequencies. For example, the acquisition unit 192 acquires radio field intensity information of a plurality of frequency bands assigned to a provider that provides a mobile phone network. The acquisition unit 192 acquires communication area information according to the specification or standard of the communication unit 12 of the own device. Further, when a SIM (Subscriber Identity Module Card) card is inserted in the communication unit 12 of the own device, the acquisition unit 192 may acquire communication area information according to the standard or type of the SIM card.

  The acquisition unit 192 may acquire radio wave intensity information in which position information indicating a position is associated with a reference radio wave intensity that is a radio wave intensity measured in advance at the position indicated by the position information. The acquisition unit 192 may further acquire measurement area information indicating an area for which the measurement unit 194, which will be described later, measures the intensity of radio waves, and notify the flight control unit 193 and the measurement unit 194 of the measurement area information. . The acquisition unit 192 may acquire not only radio waves transmitted by the base station 3 of the mobile phone network but also radio wave intensity information of radio waves that can be transmitted without license, such as Wi-Fi.

  The flight control unit 193 controls the flight mechanism 11 based on the control information received by the communication control unit 191. Further, the flight control unit 193 may control the flight mechanism 11 so as to fly along the flight path received by the communication control unit 191. The flight control unit 193 may determine the flight path based on the flight position specified by the flight position specifying unit 13 and the surrounding environment specified by the environment specifying unit 14. Further, the flight control unit 193 may specify an unreceivable area in which radio waves may not be received, and may determine a flight path so as not to include the specified unreceivable area.

  The measuring unit 194 measures the intensity of radio waves at a position during flight. The measurement unit 194 measures the intensity of the radio wave at a position included in the area indicated by the measurement area information acquired by the acquisition unit 192. The measurement unit 194 may measure the intensity of radio waves at any one of a plurality of frequencies. The measurement unit 194 notifies the storage control unit 195 of the measured radio wave intensity.

  When receiving radio waves from the base stations 3 of a plurality of mobile phone networks, the measuring unit 194 measures the strength of the radio waves for each radio wave transmitted by each base station 3. For example, the measurement unit 194 measures the intensity of the radio wave at the timing when the base station of the mobile phone network transmits the radio wave. In addition, the measurement unit 194 specifies identification information for identifying the base station 3 included in the radio wave transmitted by the base station 3, identifies the base station 3 that transmitted the radio wave, and the intensity of the radio wave transmitted by the base station 3. The storage control unit 195 may be notified in association with the measured radio wave intensity measured. Further, the measurement unit 194 may associate the frequency of the radio wave transmitted by the base station 3 with the measured radio wave intensity and notify the storage control unit 195 of the correlation between the identification information of the base station 3 and the radio wave interference degree. May be associated and notified to the storage control unit 195.

  The storage control unit 195 stores various information in the storage unit 18. The storage control unit 195 indicates that the position information included in the communication area information indicates that the position in flight is a communicable position, and the measured radio wave intensity measured by the measurement unit 194 is a reference. When it is smaller than the radio field intensity, the measured radio field intensity is stored in the storage unit 18. For example, when the difference between the measured radio wave intensity and the reference radio wave intensity is greater than or equal to the threshold value, the storage control unit 195 stores the measured radio wave intensity in the storage unit 18.

  The storage control unit 195 may store the strength of the radio wave in the storage unit 18 in response to the switching of the base station 3 of the mobile phone network that can receive the radio wave. For example, when the storage control unit 195 moves from a position capable of communicating with the base station 3a to a position where the base station 3a cannot communicate with the base station 3b, 3 is stored in the storage unit 18.

  The storage control unit 195 may store the strength of the radio wave in the storage unit 18 when the measured radio wave intensity has decreased by a threshold value or more compared to the measured radio wave intensity before a predetermined time. Specifically, the storage control unit 195 causes the storage unit 18 to store the strength of the radio wave when the measured radio wave intensity has decreased by a threshold value or more compared to the measured radio wave intensity 10 seconds ago. Note that the storage control unit 195 may store the radio wave intensity in the storage unit 18 when the measured radio wave intensity decreases by a threshold value or more compared to the measured radio wave intensity after moving a predetermined distance.

  The output unit 196 indicates that the communication area information indicates that the position in flight is a communicable position, and the measured radio wave intensity measured by the measurement unit 194 is smaller than the reference radio wave intensity. Output the measured radio wave intensity. The output unit 196 outputs the measured radio wave intensity to the information management device 2, for example. By doing so, the flying device 1 can output only the position where the intensity of the radio wave is weakened at the communicable position to the information management device 2.

  The output unit 196 outputs warning information when the difference between the measured radio wave intensity and the reference radio wave intensity is greater than or equal to a threshold value. The output unit 196 outputs warning information to a control device that controls the flying device 1, for example. The warning information is, for example, information indicating that the difference between the measured radio wave intensity and the reference radio wave intensity is equal to or greater than a threshold, or information indicating that the measured radio wave intensity is weaker than the reference radio wave intensity and communication may be disconnected.

  The flight control unit 193 may specify an unreceivable area that is a position where the radio wave of the mobile phone network may not be received based on the communication quality information acquired by the acquisition unit 192. Then, the output unit 196 may transmit warning information to a control device for controlling the aircraft while flying in a predetermined range from the unreceivable area. Furthermore, the output unit 196 may transmit warning information to the control device when it is detected that the communication path is included in the flight path included in the route determination instruction from the user.

  When the control device that controls the flying device 1 receives the warning information, the warning information is displayed. For example, the control device displays warning information superimposed on previously stored communication quality information. Specifically, the control device superimposes and displays a position where the radio wave of the base station indicated by the warning information cannot be received on a map indicating the communication area included in the communication quality information. The control device may display the warning information as text information.

In addition, the map indicating the communication area includes information indicating the area where the radio wave transmitted by the base station of the mobile phone network measured in advance is received, and the control device displays the area where the radio wave reaches in a different color from other areas. Is displayed. For example, when the control device receives information indicating that one of the base stations has stopped transmitting radio waves from the server managing the base station, the area where the radio wave transmission has stopped is different from the area where the radio waves reach. You may change the color.
By doing so, the user who uses the control device can know the region where the radio wave of the base station may not reach, so the user can control the flying device 1 while avoiding the position where the communication becomes impossible. it can.

The control device that controls the flying device 1 may display an area where radio waves of the mobile phone network reach together with the warning information. For example, the control device generates a radio wave based on the intensity of the radio wave transmitted from the base station acquired by the information management device 2 from the other flight device 1 from the information management device 2 managed by the provider who provides the communication area information. The intensity information is acquired, and an area where the radio wave transmitted by the base station reaches is displayed based on the radio wave intensity information. Specifically, the control device displays a color on the map indicating the communication area in a region where radio waves transmitted from the base station reach.
Thus, the output unit 196 outputs warning information, so that the user who controls the flying device 1 using the control device can know the change in the radio wave intensity from the radio wave intensity measured in the past.

  The control device acquires a recommended flight route recommended by the information management device 2 from the information management device 2 when the user using the control device searches the flight route with respect to the information management device 2, and transmits communication area information. You may get it. The control device may obtain from the information management device 2 a different flight route information from the recommended flight route information, for example, a detour flight route that bypasses a specific position, and a preliminary flight route that is different from the recommended flight route. In addition, when acquiring the detour flight path or the preliminary flight path, the control device may acquire the communication area information at the position on the detour flight path or the preliminary flight path.

  When the difference between the measured radio wave intensity and the reference radio wave intensity associated with the frequency at which the measurement unit 194 measured the radio wave is equal to or greater than a threshold, the output unit 196 performs measurement in association with the position where the measured radio wave intensity is measured. Outputs the signal strength. The output unit 196 of the flying device 1 outputs the strength of the radio wave associated with the frequency of the radio wave transmitted by the base station 3, and the information management device 2 manages the strength of the radio wave associated with the frequency. By doing so, the information management device 2 only needs to update the data to be changed, and therefore the processing load can be reduced.

The output unit 196 outputs the measured radio wave intensity to, for example, the information management device 2 via the communication control unit 191. The output unit 196 may output warning information to the information management device 2. Further, the output unit 196 may output the measured radio wave intensity or warning information to a predetermined terminal in addition to the information management device 2. The predetermined terminal is, for example, a control device that controls the flying device 1.
Hereinafter, the operation in which the flying device 1 measures the intensity of the radio wave will be described in detail.

[Operation in which the flying device 1 measures the intensity of radio waves]
FIG. 3 is a flowchart for explaining an operation in which the flying device measures radio waves.
First, the acquisition unit 192 of the flying device 1 acquires communication area information and a flight path from the information management device 2 (S10). Next, the flight control unit 193 of the flying device 1 flies along the acquired flight path (S12). The measuring unit 194 of the flying device 1 measures the strength of the radio wave of the mobile phone network while flying along the flight path (S14). Then, the control unit 19 of the flying device 1 determines whether or not the position information included in the communication area information indicates that the position in flight is a communicable position (S16). When the flight unit 1 does not indicate that the position in flight is a communicable position (No in S16), the flight control unit 193 returns to S12 and continues the flight along the flight path. Notify

  When the control unit 19 of the flying device 1 determines that the position in flight is a communicable position (Yes in S16), it determines whether the measured measured radio wave intensity is smaller than the reference radio wave intensity. Judgment is made (S18). When the control unit 19 determines that the measured radio field intensity is smaller than the reference radio field intensity (Yes in S18), the storage control unit 195 of the flying device 1 stores the measured radio field intensity. The storage control unit 195 of the flying device 1 does not store the measured radio wave intensity when the control unit 19 determines that the measured measured radio wave intensity is equal to or higher than the reference radio wave intensity (No in S18).

  The flying device 1 may measure the radio wave intensity at a position that has not been updated more than a predetermined number of days. FIG. 4 is a flowchart for explaining an operation in which the flying device 1 measures radio waves at a position where there is no update. First, the acquisition unit 192 of the flying device 1 acquires measurement date information indicating the date when the reference radio wave intensity associated with the communication area information and the position information is measured (S30). The acquisition unit 192 may acquire communication date information and measurement date information associated with a base station ID that identifies a base station capable of transmitting radio waves to a position where the flying device 1 is flying. Subsequently, the flight control unit 193 of the flying device 1 controls the flight mechanism 11 so as to fly at a position corresponding to the position information that has passed a predetermined number of days from the measurement date indicated by the measurement date information (S32). . Then, the measurement unit 194 of the flying device 1 measures the strength of the radio wave of the mobile phone network while flying in the position corresponding to the position information that has passed a predetermined number of days from the measurement date indicated by the measurement date information ( S34).

  The control unit 19 of the flying device 1 determines whether or not the difference between the measured radio wave intensity and the reference radio wave intensity is greater than or equal to a threshold value (S35). When the difference between the measured radio wave intensity and the reference radio wave intensity is not equal to or greater than the threshold value, the control unit 19 of the flying device 1 ends the measurement operation. The flight control unit 193 of the flying device 1 repeats the same position multiple times when the difference between the measured radio wave intensity measured by the measurement unit 194 and the reference radio wave intensity is equal to or greater than the threshold (Yes in S35). Control the flight mechanism to fly over. Specifically, the control unit 19 of the flying device 1 determines whether or not the radio wave intensity has been measured a predetermined number of times (S36). When the control unit 19 of the flying device 1 determines that the radio wave intensity has not been measured a predetermined number of times (No in S36), the measurement unit 194 of the flying device 1 increases the radio wave intensity multiple times at the same position. Then, the control unit 19 of the flying device 1 again determines whether or not the intensity of the radio wave has been measured a predetermined number of times (S36).

  When it is determined that the radio field intensity has been measured a predetermined number of times (Yes in S36), the control unit 19 of the flying device 1 calculates an average value (a) of the measured radio field intensity (S38). Subsequently, the control unit 19 of the flying device 1 calculates a difference (b) between the average value (a) and the reference radio wave intensity (S40). Then, the control unit 19 of the flying device 1 has a difference (b) between the average value (a) of the plurality of measured radio wave intensities obtained by the measurement unit 194 measuring a plurality of times and the reference radio wave intensity is equal to or greater than a threshold value. Whether or not (S42). The control unit 19 of the flying device 1 determines that the difference (b) between the average value (a) of the plurality of measured radio wave intensities obtained by the measurement unit 194 measuring a plurality of times and the reference radio wave intensity is not greater than or equal to the threshold value. In the case (No in S42), the measurement operation is terminated.

  The output unit 196 of the flying device 1 is used when the difference (b) between the average value (a) of the plurality of measured radio wave intensities obtained by the measurement unit 194 measuring a plurality of times and the reference radio wave intensity is equal to or greater than a threshold value. (Yes in S42), the measurement radio wave intensity including the average value (a) of the measurement radio wave intensity is output (S44). The output unit 196 outputs, for example, the measured radio wave intensity including the average value (a) of the measured radio wave intensity to the information management device 2.

(Modification 1)
In the above description, the storage control unit 195 indicates that the position information included in the communication area information indicates that the position in flight is a communicable position, and the intensity of the radio wave measured by the measurement unit 194. When a certain measured radio wave intensity is smaller than the reference radio wave intensity, the measured radio wave intensity is stored in the storage unit 18. However, the present invention is not limited to this, and the storage control unit 195 indicates that the position information included in the communication area information indicates that the position in flight is a position where communication is not possible, and the radio wave measured by the measurement unit 194 When the measured radio wave intensity, which is the intensity, is larger than the reference radio wave intensity, the measured radio wave intensity may be stored in the storage unit 18.

  In Modification 1, the acquisition unit 192 acquires communication area information in which position information indicating a position and communication enable / disable information indicating whether the position indicated by the position information is not communicable are associated with each other. Then, the acquisition unit 192 notifies the control unit 19 of the acquired communication area information. The control unit 19 determines whether or not the position in flight is a position where communication is not possible. When the control unit 19 determines that the position in flight is a position where communication is not possible, the control unit 19 determines whether the measured radio field intensity is greater than the reference radio field intensity. The control unit 19 notifies the storage control unit 195 when the measured radio field intensity is greater than the reference radio field intensity. The storage control unit 195 stores the measured radio wave intensity in the storage unit 18.

(Modification 2)
In the above description, the acquisition unit 192 of the flying device 1 has acquired the communication area information, but the acquisition unit 192 may not acquire the communication area information. When the acquisition unit 192 does not acquire the communication area information, the output unit 196 outputs the measured radio wave intensity in association with the position where the measured radio wave intensity is measured without comparing the measured radio wave intensity with the reference radio wave intensity. Further, when the output unit 196 measures the intensity of the radio wave at a position not included in the communication area information acquired by the acquisition unit 192, the output radio wave intensity is measured without comparing the measured radio wave intensity with the reference radio wave intensity. The measured radio wave intensity may be output in association with the detected position.

(Modification 3)
In the above description, the flying device 1 has the output unit 196. However, the present invention is not limited to this, and the flying device 1 may not have the output unit 196. The storage unit 18 of the flying device 1 is, for example, an SD memory card, a multi media card, a compact flash (CF (registered trademark)), a USB flash drive, or a removable HDD. The storage control unit 195 stores the measured radio wave intensity in the storage unit 18. The user who uses the flying device 1 removes the storage unit 18 of the flying device 1 after measuring the intensity of the radio wave while the flying device 1 flies along the flight path. Then, for example, the user attaches the storage unit 18 of the flying device 1 to the information management device 2. In this way, the information management device 2 can acquire the measured radio wave intensity stored in the storage unit 18 of the flying device 1.
