  In the flight system S, the control device 1 and the flight device 2 can communicate using either or both of the first wireless communication line W1 and the second wireless communication line W2. When the flight device 2 receives the same control information via each of the first wireless communication line W1 and the second wireless communication line W2, the flight device 2 performs flight control using the previously received control information. In addition, the control of the flying device 2 includes the control of the flight direction and the flight speed of the control device 1.

[Configuration of the control device 1]
FIG. 2 is a diagram illustrating a configuration of the control device 1. The control device 1 includes a display unit 11, a speaker 12, a communication unit 13, a storage unit 14, an operation unit 15, and a control unit 16. The control unit 16 includes a display control unit 161, an operation reception unit 162, a control information generation unit 163, and a communication control unit 164.

  The display unit 11 is a display that displays display data input from the display control unit 161. For example, the display unit 11 displays information necessary for the user to operate the flying device 2 when the flying device 2 flies. The speaker 12 is an audio output unit for outputting audio. The display unit 11 and the speaker 12 constitute a notification unit 20 for notifying a user of an error or the like.

  The operation unit 15 is a device for a user to perform an operation for maneuvering the flying device 2, and includes, for example, a joystick or a volume for controlling a flight direction and a flight speed. The operation unit 15 further includes a touch panel provided on the surface of the display unit 11. The operation unit 15 notifies the operation reception unit 162 of a signal corresponding to the operation content of the user.

  The communication unit 13 is a communication module that transmits and receives radio waves for communication using the first wireless communication line W1 and the second wireless communication line W2a. The communication unit 13 includes a modulator that modulates transmission data input from the communication control unit 164, and a high-frequency unit that transmits the modulated data as a high-frequency signal in a frequency band assigned to Wi-Fi or LTE. . The communication unit 13 includes a demodulator that demodulates a high-frequency signal received from the flying device 2 by the high-frequency unit. The demodulator inputs the demodulated received data to the communication control unit 164.

  Further, the communication unit 13 measures the communication quality of the first wireless communication line W1 and the second wireless communication line W2a. For example, the radio field intensity included in the communication quality of the first wireless communication line W1 and the second wireless communication line W2a is measured.

  A selection screen for selecting whether or not the first wireless communication line W1 and the second wireless communication line W2 are used will be described with reference to FIG. This selection screen is displayed on the display unit 11 constituting the touch panel, and is a screen for the user to select a communication line used for communication of flight data and non-flight data between the control device 1 and the flight device 2. It is. FIG. 3 shows a state before accepting the user's selection. The selection screen includes an icon A1 indicating flight data, an icon A2 indicating non-flight data, an icon A3 indicating an LTE icon, an icon A4 indicating Wi-Fi, and an off icon indicating that the corresponding wireless communication line is not used. A5, an on icon A6 indicating that the corresponding wireless communication line is used, a cancel button A7, and a decision button A8 are displayed.

  This selection screen indicates that LTE is in an off state for communication of flight data, and LTE is not used for communication of flight data. On the other hand, it is shown that Wi-Fi is in an on state for communication of flight data, and Wi-Fi is used for communication of flight data. Also, LTE is turned on for non-flight data communication, and LTE is used for flight data communication. On the other hand, Wi-Fi is off and Wi-Fi is not used for non-flight data communication.

  The off icon A5 and the on icon A6 are switches for switching whether or not the wireless communication line is used. When the user selects the off icon A5 on the selection screen, the off icon A5 is switched to the on icon A6. For example, if the user selects an off icon A5 indicating that LTE is not used for flight data communication, the off icon A5 is switched to the on icon A6, and LTE is used for flight data communication. Similarly, when the user selects the on icon A6, the on icon A6 is switched to the off icon A5.

  When the user selects the determination button A8, the operation reception unit 162 stores in the storage unit 14 the use / non-use state displayed for LTE and Wi-Fi for the communication of the flight data and the non-flight data. To do. The communication control unit 164 causes the communication unit 13 to communicate the flight data and the non-flight data using the wireless communication lines that are shown to be in the ON state. On the other hand, when the user selects the cancel button A7, whether or not each wireless communication line is used is not changed, and the state before the selection screen is displayed is maintained.

  Note that since the flight data includes control information for maneuvering the rotor and power unit of the flying device 2, it is necessary to communicate the flying data when the flying device 2 is flying. For this reason, when the user selects the decision button A8 in a state where the off-icon A5 is assigned to any of the Wi-Fi and LTE wireless communication lines for the communication of the flight data, the control information generation unit 163 Displays an error.

  The storage unit 14 in FIG. 2 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The storage unit 14 stores a program executed by the control unit 16. The storage unit 14 is used as a work memory for the control unit 16 and temporarily stores flight data and non-flight data received from the flying device 2. In addition, when the user changes the setting of whether or not the wireless communication line is used on the wireless communication line selection screen, the storage unit 14 stores the changed wireless communication line setting information.

  The control unit 16 is, for example, a CPU (Central Processing Unit), and as a display control unit 161, an operation reception unit 162, a control information generation unit 163, and a communication control unit 164 by executing a program stored in the storage unit 14. Function. The operation receiving unit 162 specifies the operation content of the user based on the signal indicating the operation content input from the operation unit 15. The operation reception unit 162 notifies the specified operation content to the display control unit 161 and the control information generation unit 163. In addition, the operation reception unit 162 receives an operation of selecting at least one of the first wireless communication line W1 and the second wireless communication line W2 on the selection screen for the communication of the flight data and the non-flight data. Specifically, the operation reception unit 162 receives a user operation for selecting whether to use the first wireless communication line W1 and the second wireless communication line W2.

  The control information generation unit 163 generates control information for controlling the flying device 2 based on the operation content notified from the operation reception unit 162. The control information generation unit 163 generates control information including the flight direction and the flight speed specified by the user, and inputs the generated control information to the communication control unit 164. In addition, when the operation reception unit 162 receives a user operation for selecting that neither the first wireless communication line W1 nor the second wireless communication line W2 is used for communication of flight data on the selection screen, the control information generation unit 163 Causes the notification unit 20 to output an error. For example, the control information generation unit 163 displays a message that prompts the user to select on the selection screen that one of the first wireless communication line W1 and the second wireless communication line W2 is used for the flight data communication. 11 is displayed.

  The display control unit 161 displays the selection screen on the display unit 11. For example, when the user performs a display screen display operation, the display control unit 161 displays the selection screen. When the user performs a display screen display operation, the display control unit 161 reads the setting of whether or not the first wireless communication line W1 and the second wireless communication line W2 are used from the storage unit 14 and displays them on the selection screen. Let In addition, the display control unit 161 determines a combination recommended to the user regarding whether or not the first wireless communication line W1 and the second wireless communication line W2 are used for each of the flight data and the non-flight data communication. It also functions as a communication line management means. The display control unit 161 displays a selection screen when the combination recommended to the user is different from the combination held in the storage unit 14 regarding the presence / absence of use of the first wireless communication line W1 and the second wireless communication line W2. Display. On the selection screen, the display control unit 161 displays a combination recommended to the user in a state before accepting selection of the wireless communication line from the user, and the user edits this combination so that the first wireless communication line is displayed. Whether to use W1 and the second wireless communication line W2 is selected.

  The display control unit 161 determines a combination recommended to the user when the control device 1 is powered on, for example. The display control unit 161 determines a combination recommended to the user on the selection screen. Whether the combination recommended to the user is used as a combination of whether or not the wireless communication line is used for communication of flight data and non-flight data. Whether or not is selected by the user on the selection screen.

  More specifically, the display control unit 161 reads out distribution information indicating the distribution of the radio field intensity of the second wireless communication line W2 for each area from the storage unit 14. Based on this distribution information, the display control unit 161 uses at least one of the first wireless communication line W1 and the second wireless communication line W2 for each of the flight data and the non-flight data. The presence or absence of use is determined, and the presence or absence of this use is displayed on the selection screen of the display unit 11.

  Specifically, the display control unit 161 refers to the communication quality of the second wireless communication line W2 at the current position of the flying device 2 in the distribution information. When the communication quality at the current position is good, for example, when the radio wave intensity included in the communication quality of the second wireless communication line W2 is higher than the threshold value, the display control unit 161 The second wireless communication line W2 is displayed on the display unit 11 as being used. This threshold value is, for example, a value that does not hinder the operation of the flying device 2 by the communication of the flight data via the second wireless communication line W2. On the other hand, when the communication quality at the current position of the second wireless communication line W2 is not good in the distribution information, for example, when the radio wave intensity included in the communication quality of the second wireless communication line W2 is equal to or lower than the above threshold value, the flight For the data communication, the second wireless communication line W2 is not used and is displayed on the display unit 11.

  In addition, as a combination recommended to the user, the display control unit 161 displays distribution information at frequencies that can be used for communication via the second wireless communication line W2 for communication of flight data and non-flight data. Based on this, the presence or absence of use of at least one of the first wireless communication line W1 and the second wireless communication line W2 is determined, and the presence or absence of this use is displayed on the selection screen of the display unit 11. The second wireless communication line W2 includes two or more wireless communication lines having different frequencies, and includes, for example, LTE having a frequency band of 700 MHz band, 3.5 GHz band, and 2 GHz band. The base station selects an LTE that can be used in the second wireless communication line W2 from the LTE of these frequency bands. The display control unit 161 reads the LTE distribution information of the frequency band selected by the base station from the storage unit 14, and when the LTE radio wave intensity of the frequency band selected by the base station is higher than the threshold in the distribution information, For the communication of the flight data, the selection screen is displayed as a state in which LTE is used.

  In addition, the frequency which can be used changes with the model numbers and kinds of the communication module and SIM (Subscriber Identity Module) card which are mounted in the control device 1 and the flying device 2. The display control unit 161 does not cause the display unit 11 to display LTE in a frequency band that has not been selected by the base station.

  Further, the display control unit 161 displays, on the selection screen, a combination recommended to the user as to whether or not the first wireless communication line W1 is used based on the communication quality of the first wireless communication line W1 measured by the communication unit 13. . For example, since the first wireless communication line W1 is a wireless communication line that does not pass through a base station of a mobile phone network, there is an advantage that a delay in the behavior of the flying device 2 hardly occurs during maneuvering. For this reason, the display control unit 161 flies in a combination recommended to the user when the first wireless communication line W1 can be used and the first wireless communication line W1 is not used for communication of flight data. For the communication of the business data, the display unit 11 is displayed as a state in which the first wireless communication line W1 is used.

  In addition, when the communication state is not good during communication through the first wireless communication line, for example, before the predetermined time has elapsed since the flight data or the non-flight data was transmitted using the first wireless communication line W1. When the flight data or the response to the non-flight data is not received, the display control unit 161 displays on the selection screen that the second wireless communication line W2 is used to transmit the flight data and the non-flight data.

  In addition, it is preferable that the communication state of the control device 1 and the flying device 2 can be confirmed before the user selects whether or not the wireless communication line is used. Therefore, for example, before displaying the selection screen, the display control unit 161 determines whether or not the control device 1 and the flying device 2 are in a usable state, and the radio wave status and the battery remaining in the control device 1 and the flying device 2. Each amount may be displayed.

  The communication control unit 164 causes the communication unit 13 to communicate the flight data with the flying device 2 using the wireless communication line selected for the communication of the flight data, and selects the non-flight data for communication. The non-flight data is transmitted to the communication unit 13 with the flying device 2 by using the wireless communication line.

[Configuration of the flying device 2]
FIG. 4 is a diagram illustrating a configuration of the flying device 2. The flying device 2 includes a camera 21, a detection unit 22, a communication unit 23, a flight mechanism 24, a storage unit 25, and a control unit 26. The control unit 26 includes a flight information generation unit 261, a transmission control unit 262, a reception control unit 263, and a flight control unit 264.

  The camera 21 captures the periphery of the flying device 2 and generates image data. The camera 21 outputs the generated image data to the flight information generation unit 261 as non-flight data. The detection unit 22 includes, for example, an acceleration sensor, a GPS (Global Positioning System) receiver, a pressure sensor, and a thermometer, and for the flight of the flying device 2 such as the flight speed, inclination, and flight position of the flying device 2. The flight data used and the non-flight data that is not used for the flight of the flight device 2 such as atmospheric pressure and temperature are output to the flight information generation unit 261.

  The communication unit 23 is a communication module that transmits and receives radio waves for communication via the first wireless communication line W1 and the second wireless communication line W2, and has a function equivalent to that of the communication unit 13.

  The flight mechanism 24 includes a rotor, a power unit, and the like. The flight mechanism 24 can change the flight speed and the flight direction by operating these mechanisms based on the control of the flight control unit 264.

  The storage unit 25 is a storage medium including a ROM and a RAM. The storage unit 25 stores a program executed by the control unit 26. The storage unit 25 is used as a work memory of the control unit 26, and temporarily stores control information received from the control device 1, for example.

  The control unit 26 is a CPU, for example. The control unit 26 functions as a flight information generation unit 261, a transmission control unit 262, a reception control unit 263, and a flight control unit 264 by executing a program stored in the storage unit 25.

  The flight information generation unit 261 acquires image data input from the camera 21. In addition, the flight information generation unit 261 acquires flight data and non-flight data indicating the state of the flight device 2 input from the detection unit 22 and inputs them to the transmission control unit 262.

  The transmission control unit 262 transmits the flight data and the non-flight data input from the flight information generation unit 261 to the control device 1 via the communication unit 23. Further, the transmission control unit 262 may notify the control device 1 of the state information indicating the state of the first wireless communication line W1 or the second wireless communication line W2 as flight data. For example, the state information indicating the state of the first wireless communication line W1 or the second wireless communication line W2 includes the electric field strength of the radio wave of the first wireless communication line W1 or the second wireless communication line W2, the control information transmitted by the control device 1. Is the time required to reach the reception control unit 263.

  The flight control unit 264 controls the flight state by controlling the flight mechanism 24 based on the control information included in the flight data received from the control device 1. When the flight control unit 264 receives control information redundantly via the first wireless communication line W1 and the second wireless communication line W2, the flight control unit 264 controls the flight state based on the control information previously received by the reception control unit 263. To do.

  Further, since the first wireless communication line W1 does not pass through the base station, the communicable range of the first wireless communication line W1 is limited to the periphery of the control device 1, and is within 1 km from the control device 1, for example. Therefore, in the state where the communication unit 23 uses the first wireless communication line W1 and does not use the second wireless communication line W2 for communication of flight data, the flight range of the flying device 2 is the control device. Limited to a predetermined distance from 1. Therefore, the flight control unit 264 acquires the flight start position and the current position where the flight has started by GPS, and performs flight control so that the current position is within a predetermined range, for example, within 1 km from the flight start position.

[Configuration of Communication Control Unit 164]
FIG. 5 is a block diagram illustrating an example of a detailed configuration of the communication control unit 164 of the control device 1 of FIG. The communication control unit 164 includes a radio control signal generation unit 31, a first radio control signal output unit 32, and a second radio control signal output unit 33. The radio control signal generation unit 31 generates a first radio control signal and a second radio control signal based on the selection received by the operation reception unit 162. The first wireless control signal is a signal that instructs the flying device 2 whether or not the first wireless communication line W1 is used in the communication of the flight data and the non-flight data received by the operation reception unit 162 on the selection screen. The second radio control signal is a signal that instructs the flying device 2 whether or not the second radio communication line W2 is used in the communication of the flight data and the non-flight data.

  The first radio control signal output unit 32 causes the communication unit 13 to transmit the first radio control signal to the flying device 2 using the second radio communication line W2. In the state where the first wireless communication line W1 is not used for both the flight data and the non-flight data communication, the communication unit 13 of the flying device 2 does not receive the first wireless communication line W1. In this case, the first radio control signal output unit 32 cannot transmit a control signal for switching whether to use the first radio communication line W1 through the first radio communication line W1. Therefore, the first radio control signal output unit 32 causes the first radio control signal to be transmitted using the second radio communication line W2 instead of the first radio communication line W1. Similarly, the second radio control signal output unit 33 causes the communication unit 13 to transmit the second radio control signal to the flying device 2 using the first radio communication line W1.

  By adopting such a configuration, the user selects, on the selection screen, a wireless communication line that is used for communication of flight data and non-flight data among the first wireless communication line and the second wireless communication line. be able to. For example, a user who wants to improve the responsiveness of maneuvering can suppress the delay of the control signal by using the first wireless communication line that does not pass through the base station 3 of the mobile phone network.

[Radio wave intensity map]
FIG. 6 shows an example of the operation of the control device 1. In FIG. 6, distribution information indicating the distribution of communication quality of the second wireless communication line W2 for each area is displayed as a radio wave intensity map B1. In the radio wave intensity map B1, as indicated by the hatching label B2, areas with different radio wave intensities of the second wireless communication line are assigned with different hatchings. The radio wave intensity map B1 is displayed in association with the altitude of the flying device 2 from the ground, and on this display screen, the radio wave intensity map B1 at an altitude of about 35 m is shown. Every time the user selects the button B3, a radio wave intensity map in which the altitude is increased by 5 m is displayed. In addition, every time the user selects the button B4, a radio wave intensity map in which the altitude is reduced by 5 m is displayed. The icon B5 in the center of the radio wave intensity map B1 indicates the flight position and height of the flying device 2. On this display screen, the flying device 2 is located at an altitude of 34.2 m from the ground.

  Pictograms B6 and B7 at the left end and right end of the display screen indicate the remaining battery levels of the control device 1 and the flying device 2, respectively, and pictograms B8 and B9 at the left end and right end of the display screen indicate the control device 1 and the flying device 2, respectively.

[Flowchart for operation of control device 1]
FIG. 7 is a flowchart showing an example of the operation of the control device 1, and shows recommended setting display processing for displaying a selection screen. This process is started, for example, when the power to the control device 1 is turned on.

  First, the control information generation unit 163 acquires the current position of the flying device 2 from the GPS mounted on the flying device 2 using a wireless communication line (S11). Next, the display control unit 161 reads LTE communication quality distribution information from the storage unit 14 (S12). The communication unit 13 measures the communication quality of Wi-Fi (S13). Further, the display control unit 161 is a combination recommended to the user regarding whether or not the first wireless communication line W1 and the second wireless communication line W2 are used for each of the first wireless communication line W1 and the second wireless communication line W2. Is determined (S14).

  When the combination determined by the display control unit 161 is changed from the combination of presence / absence of use of each of the LTE and Wi-Fi wireless communication lines before the recommended setting display process is started (YES in S15) The control unit 161 displays the combination determined by the display control unit 161 on the selection screen (S16). On this selection screen, the user selects whether to use the first wireless communication line W1 and the second wireless communication line W2. On the other hand, in step S15, when the combination determined by the display control unit 161 is the same as the state before the start of the recommended setting display process (NO in S15), the process ends without displaying the selection screen.

  FIG. 8 is a flowchart showing an example of the wireless communication line selection process in step S14 of FIG. First, the display control unit 161 compares the Wi-Fi radio wave intensity with a threshold value (S21). This threshold value is, for example, a value that does not hinder maneuvering of the flying device 2 by communication of flight data via Wi-Fi. When the Wi-Fi radio wave intensity is larger than the threshold (YES in S21), the display control unit 161 uses Wi-Fi for communication of flight data and non-flight data in a combination recommended to the user displayed on the selection screen. Is determined to be displayed as a use state (S22). Next, the display control unit 161 compares the LTE radio wave intensity with a threshold value (S23). This threshold value is, for example, a value that does not hinder the operation of the flying device 2 by communication of flight data via LTE. When the LTE radio field intensity is greater than the threshold (YES in S23), the display control unit 161 uses LTE for communication of flight data and non-flight data in a combination recommended to the user displayed on the selection screen. Is displayed, and the process is terminated (S24).

  When the Wi-Fi radio wave intensity is equal to or less than the threshold value in step S21 (NO in S21), the display control unit 161 uses Wi-Fi for communication of flight data and non-flight data in a combination recommended by the user. It decides to display as a state which does not carry out, and moves to determination of step S23 (S25). In addition, when the LTE radio wave intensity is equal to or lower than the threshold value in step S23 (NO in S23), the display control unit 161 does not use LTE for the communication of the flight data and the non-flight data in the combination recommended to the user. Is determined to be displayed, and the process ends (S26).

[Effects of Control Device 1 of Embodiment 1]
According to the present embodiment, the user can select a wireless communication line used for communication of flight data and non-flight data from the first wireless communication line and the second wireless communication line on the selection screen. it can. Therefore, the user can select a wireless communication line according to needs.

A combination of presence or absence of use can be recommended. For this reason, the user can select the use / non-use of the wireless communication line with reference to the recommended combination, so that the user's selection can be facilitated. Further, when the user selects any one of the wireless communication lines including the second wireless communication line W2, the display control unit 161 performs wireless communication based on the distribution information on the usable frequency of the second wireless communication line W2. A combination of whether or not a line is used can be recommended. For this reason, the user can select whether or not the wireless communication line is used with reference to the recommended combination, and thus the user can be more easily selected.

  In addition, when a user operation for selecting that neither the first wireless communication line W1 nor the second wireless communication line W2 is used for communication of flight data on the selection screen is performed, the control information generation unit 163 displays the notification unit. 20 causes an error to be output. For this reason, it is possible to prevent the flight data 2 from being communicated due to an erroneous operation by the user and the flight apparatus 2 from being impossible to control.

  Further, when the first wireless communication line W1 can be used and the first wireless communication line W1 is not used for the flight data communication, the display control unit 161 performs the flight data communication on the selection screen. On the other hand, since the first wireless communication line W1 is displayed as being used, the display control unit 161 indicates that the user uses the first wireless communication line W1 when the first wireless communication line W1 is available. Can be recommended. In addition, when a response to the flight data or the non-flight data is not received before a predetermined time has elapsed since the flight data or the non-flight data was transmitted using the first wireless communication line W1, a display is displayed. Since the control unit 161 displays the selection screen as a state in which the second wireless communication line W2 is used for transmission of flight data and non-flight data, it is used when the communication quality of the first wireless communication line W1 is not good. The user can be recommended to change the wireless communication line to be changed to the second wireless communication line W2.

  Also, a first radio control signal instructing whether or not the first radio communication line W1 is used is output to the flying device via the second radio communication line W2, and the second radio instructing whether or not the second radio communication line W2 is used. By outputting a control signal to the flying device via the first wireless communication line W1, use of one wireless communication line is performed within an area where both of the two wireless communication lines can be used. The communication of the other wireless communication line can be maintained even when the presence or absence is switched.

<Embodiment 2>
In the first embodiment, an example in which the display control unit 161 of the control device 1 acquires LTE communication quality distribution information at the current position of the flying device 2 has been described. On the other hand, in the present embodiment, the user saves the flight route of the flying device 2 in the server, and the display control unit 161 of the control device 1 acquires LTE communication quality distribution information corresponding to this flight route. An example of the case will be described.

  First, the user creates a flight route of the flying device 2 using the control device 1. The flight route is a route on which the flying device 2 flies.

The flight system S of the present embodiment further includes a server connected to the control device 1 via the second wireless communication line W2, and the communication control unit 164 uses the second wireless communication line W2 to create a flight created in advance. The route is transmitted to the server by the communication unit 13, and the server stores this flight route. By doing so, the control device 1 does not need to increase the storage capacity of the storage unit 14 for storing a large number of flight routes.

  The operation accepting unit 162 of the control device 1 accepts a user operation for selecting one of the flight routes stored in the server before the flight of the flying device 2, and the communication control unit 164 performs the flight selected by the user. The communication unit 13 transmits a route transmission request to the server. In response to this transmission request, the server transmits the flight route selected by the user to the control device 1, and the communication unit 13 receives the flight route. Further, the communication control unit 164 causes the flying device 2 to fly based on the received flight route. For example, the control information generation unit 163 sequentially generates control information for controlling the flying device 2 so that the flying device 2 flies along the flight route, and the communication control unit 164 transmits the control information to the flying device 2. Then, the communication unit 13 is caused to transmit the flight data including the generated control information.

[Flowchart for operation of control device 1]
FIG. 9 is a flowchart showing an example of the operation of the control device 1 of the present embodiment, and shows an example of a recommended setting display process. This process is started, for example, when the control device 1 is connected to the server via the second wireless communication line W2 in order to select one of the flight routes of the flight device 2 stored in the server. The same processing steps as those in FIG. 6 are denoted by the same reference numerals and description thereof is omitted.

  First, when the user selects one of the flight routes stored in the server, the communication unit 13 of the control device 1 receives the selected flight route from the server (S31). Next, the display control unit 161 reads out LTE communication quality distribution information of the area including the selected flight route from the storage unit 14 (S32). After acquiring the Wi-Fi communication quality distribution information (S13), the display control unit 161 refers to the LTE distribution information to determine whether the LTE communication quality in the frequency band selected by the base station is good or not. Is determined (S34).

  FIG. 10 is a flowchart showing an example of the wireless communication line selection process in step S34 of FIG. First, the display control unit 161 compares the LTE radio wave height selected by the base station with a threshold (S41). Next, when the LTE radio field intensity is greater than the threshold (YES in S41), the display control unit 161 displays the state in which LTE is used for communication of flight data and non-flight data in a combination recommended by the user. (S42). Further, the display control unit 161 compares the Wi-Fi radio wave intensity with a threshold value (S43). When the Wi-Fi radio wave intensity is larger than the threshold, the display control unit 161 determines to display the state where the Wi-Fi is used for the communication of the flight data and the non-flight data in the combination recommended by the user. The process is terminated (S44).

  When the LTE radio wave intensity is equal to or lower than the threshold value in step S41 (NO in S41), the display control unit 161 displays the state in which LTE is not used for communication of flight data and non-flight data in a combination recommended to the user (S45). Further, it is determined to display the state where Wi-Fi is used for the communication of the flight data and the non-flight data in the combination recommended by the user, and the process ends (S46). Further, when the Wi-Fi radio wave intensity is equal to or less than the threshold value in step S43, the display control unit 161 sets the state in which Wi-Fi is not used for communication of flight data and non-flight data in a combination recommended to the user. It is determined to be displayed, and the process ends (S47).

[Effects of Control Device 1 of Embodiment 2]

At least one of the lines W2 is displayed on the selection screen. With such a configuration, the user can select whether to use the first wireless communication line W1 and the second wireless communication line W2 with reference to a recommended combination based on the distribution state. The presence / absence selection can be facilitated.

  When the radio field intensity included in the communication quality of the second wireless communication line is lower than the threshold value, the display control unit 161 uses the first wireless communication line W1 for the flight data communication. 11 is displayed on the selection screen, the user can be recommended to change the wireless communication line to the first wireless communication line W1 when the communication quality of the second wireless communication line is not good.

  The display control unit 161 may display the radio wave intensity map B1 in FIG. 6 before or when the user selects the flight route. By adopting such a configuration, the user refers to the radio wave intensity map B1 and confirms an area where the communication state of the second wireless communication line W2 is good, thereby selecting a flight route with a good communication state. be able to. In particular, since the display control unit 161 displays the radio wave intensity at the frequency selected by the base station in the radio wave intensity map B1, the user can grasp the radio wave intensity in communication between the control device 1 and the flying device 2.
