  In the flight system S, the control device 1 and the flight device 2 can communicate using one 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 through each of the first wireless communication line W1 and the second wireless communication line W2, flight control is performed using the control information received earlier. The steering of the flight device 2 includes control of the flight direction and flight speed of the steering device 1.

[Configuration of control device 1]
FIG. 2 is a diagram showing the 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 for displaying display data input from the display control unit 161, and displays, for example, information necessary for the user to maneuver the flight device 2 when the flight device 2 is flying. 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 the user of an error or the like.

  The operation unit 15 is a device for the user to operate the flight device 2 and includes, for example, a joystick or a volume for controlling the flight direction and the 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 according to the content of the user's operation.

  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 of a frequency band allocated to Wi-Fi or LTE. . The communication unit 13 also has a demodulator that demodulates the high frequency signal received by the high frequency unit from the flight device 2. The demodulator inputs the reception data after demodulation to the communication control unit 164.

  The communication unit 13 also measures the communication quality of the first wireless communication line W1 and the second wireless communication line W2a. For example, the radio wave 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 to use the first wireless communication line W1 and the second wireless communication line W2 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. In FIG. 3, the state before accepting the user's selection is shown. The selection screen includes an icon A1 indicating data for flight, an icon A2 indicating data for non-flight, an icon A3 indicating 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 determination button A8 are displayed.

  In this selection screen, it is shown that LTE is off for communication of flight data, and LTE is not used for communication of flight data. On the other hand, for communication of flight data, it is shown that Wi-Fi is on, and Wi-Fi is used for communication of flight data. Also, for communication of non-flight data, LTE is turned on, and LTE is used for communication of flight data. On the other hand, Wi-Fi is off, and Wi-Fi is not used to communicate non-flying data.

  The off icon A5 and the on icon A6 are switches for switching use / non-use of the wireless communication line, and 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, when the user selects an off icon A5 indicating that LTE is not used for communication of flight data, the off icon A5 is switched to the on icon A6, and LTE is used for communication of flight data. 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 receiving unit 162 stores in the storage unit 14 the state of use or non-use displayed for LTE and Wi-Fi for communication of flight data and non-flight data. Do. The communication control unit 164 causes the communication unit 13 to communicate with the data for flight and the data for non-flight using the wireless communication line shown to be in the on state. On the other hand, when the user selects the cancel button A7, the presence or absence of use of each wireless communication line is not changed, and the state before the selection screen is displayed is maintained.

  In addition, since the data for flight includes control information for operating the rotor, the power unit and the like of the flight device 2, it is necessary to communicate the data for flight at the time of flight of the flight device 2. Therefore, when the user selects the determination button A8 in a state where the off icon A5 is allocated to both the Wi-Fi and LTE wireless communication channels for communication of flight data, the control information generation unit 163 Will display an error.

  The storage unit 14 in FIG. 2 is a storage medium including a read only memory (ROM), a random access memory (RAM), and the like. The storage unit 14 stores a program that the control unit 16 executes. The storage unit 14 is also used as a work memory of the control unit 16 and temporarily stores flight data and non-flight data received from the flight device 2. In addition, when the user changes the setting of use / non-use of the wireless communication line on the selection screen of the wireless communication line, the storage unit 14 stores setting information of the wireless communication line after the change.

  The control unit 16 is, for example, a central processing unit (CPU), and executes the program stored in the storage unit 14 to be used as the display control unit 161, the operation reception unit 162, the control information generation unit 163, and the communication control unit 164. Function. The operation accepting 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 display control unit 161 and the control information generation unit 163 of the specified operation content. In addition, the operation accepting unit 162 accepts an operation of selecting at least one of the first wireless communication line W1 and the second wireless communication line W2 in the selection screen for communication of flight data and non-flight data. Specifically, the operation reception unit 162 receives a user operation for selecting the use of the first wireless communication line W1 and the second wireless communication line W2.

  Control information generation unit 163 generates control information for controlling flight device 2 based on the operation content notified from operation reception unit 162. The control information generation unit 163 generates control information including the flight direction and the flight speed designated by the user, and inputs the generated control information to the communication control unit 164. When operation reception unit 162 receives a user operation to select not to use either first wireless communication line W1 or second wireless communication line W2 for communication of flight data on the selection screen, 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 prompting the user to select on the selection screen that either the first wireless communication line W1 or the second wireless communication line W2 should be used for communication of flight data. Display on 11

  The display control unit 161 causes the display unit 11 to display a selection screen. The display control unit 161 displays the selection screen, for example, when the user performs the display operation of the selection screen. When the user performs the display operation of the selection screen, the display control unit 161 reads out the setting of presence / absence of use of the first wireless communication line W1 and the second wireless communication line W2 from the storage unit 14 and displays the setting on the selection screen. Let Further, the display control unit 161 determines a combination recommended for the user as to whether or not the first wireless communication line W1 and the second wireless communication line W2 are used for communication of flight data and non-flight data. It also functions as a communication line management means. The display control unit 161 selects the selection screen when the combination recommended for the user is different from the combination held in the storage unit 14 as to whether or not the first wireless communication line W1 and the second wireless communication line W2 are used. Display. On the selection screen, the display control unit 161 displays a combination recommended for the user in a state before receiving a selection of a wireless communication line from the user, and the user edits the combination to obtain the first wireless communication line. The use of W1 and the second wireless communication line W2 is selected.

  The display control unit 161 determines, for example, a combination recommended for the user when the control device 1 is powered on. The display control unit 161 determines the combination recommended for the user on the selection screen, but does it use the combination recommended for the user as the combination of use / non-use of the wireless communication line for communication of flight data and non-flight data? It is assumed that the user selects in the selection screen whether or not.

  More specifically, the display control unit 161 reads from the storage unit 14 distribution information indicating the distribution of the radio wave intensity of the second wireless communication line W2 for each area. The display control unit 161 uses the wireless communication line of 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 based on the distribution information. The presence or absence of this use is determined 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 flight device 2 in the distribution information. If the communication quality at the current position is good, for example, if the radio wave intensity included in the communication quality of the second wireless communication line W2 is higher than the threshold, the display control unit 161 transmits the flight data communication. It is displayed on the display unit 11 as the state of using the second wireless communication line W2. The threshold is, for example, a value that does not hinder the operation of the flight device 2 by communication of 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 strength included in the communication quality of the second wireless communication line W2 is equal to or less than the above threshold, The second wireless communication line W2 is not used for the communication of data for display on the display unit 11.

  In addition, as a combination recommended for the user, the display control unit 161 distributes information on frequencies available for communication via the second wireless communication line W2 to each of communication for flight data and non-flight data. Based on the determination, 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 the 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, for example, LTE in 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 channel W2 among the LTEs in these frequency bands. The display control unit 161 reads out the LTE distribution information of the frequency band selected by the base station from the storage unit 14, and if the radio wave intensity of LTE in the frequency band selected by the base station is higher than the threshold in the distribution information, The communication of flight data is displayed on the selection screen as the state of using LTE.

  The usable frequency differs depending on the model number and type of the communication module or SIM (Subscriber Identity Module) card mounted on the control device 1 and the flight device 2. The display control unit 161 does not cause the display unit 11 to display LTE of the frequency band not selected by the base station.

  Further, based on the communication quality of the first wireless communication line W1 measured by the communication unit 13, the display control unit 161 causes the selection screen to display a combination recommended to the user as to whether the first wireless communication line W1 is used. . 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 telephone network, there is an advantage that the behavior of the flight device 2 is unlikely to be delayed during operation. Therefore, when the first wireless communication line W1 is usable and the first wireless communication line W1 is not used for communication of flight data, the display control unit 161 can fly in a combination recommended for the user. The display unit 11 is made to display the state of using the first wireless communication line W1 for the communication of the data for communication.

  Also, when the communication state is not good during communication by the first wireless communication line, for example, before transmission of flight data or non-flight data using the first wireless communication line W1, before a predetermined time has elapsed. If the response to the flight data or the non-flight data is not received, the display control unit 161 causes the selection screen to display the use of the second wireless communication line W2 for transmission of the flight data and the non-flight data.

  It is preferable that the communication state of the control device 1 and the flight device 2 can be confirmed before the user selects the use of the wireless communication line. Therefore, for example, before displaying the selection screen, the display control unit 161 determines whether the control device 1 and the flight device 2 are in the usable state, and the radio wave condition and the battery remaining in the control device 1 and the flight device 2. The amount may be displayed respectively.

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

[Configuration of Flight Device 2]
FIG. 4 is a view showing the configuration of the flight device 2. The flight 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 flight 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 and a GPS (Global Positioning System) receiver, a pressure sensor, and a thermometer, and for the flight of the flight device 2, such as the flight speed, inclination, and flight position of the flight device 2. The flight data to be used and non-flight data not used for flight of the flight device 2 such as air 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 with the first wireless communication line W1 and the second wireless communication line W2, and has the same function as 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, a RAM, and the like. The storage unit 25 stores a program that the control unit 26 executes. The storage unit 25 is also used as a work memory of the control unit 26, and temporarily stores, for example, control information received from the control device 1.

  The control unit 26 is, for example, a CPU. 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 the program stored in the storage unit 25.

  The flight information generation unit 261 acquires image data input from the camera 21. Further, 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 the data 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 through the communication unit 23. Further, the transmission control unit 262 may notify the control device 1 of state information indicating the state of the first wireless communication line W1 or the second wireless communication line W2 as data for flight. For example, the state information indicating the state of the first wireless communication line W1 or the second wireless communication line W2 is 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 taken for the reception control unit 263 to reach.

  The flight control unit 264 controls the flight state by controlling the flight mechanism 24 based on control information included in the flight data received from the flight control device 1. When the flight control unit 264 receives control information in duplicate 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 received earlier by the reception control unit 263. 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, for example, within 1 km from the control device 1. Therefore, when the communication unit 23 uses the first wireless communication line W1 for communication of flight data and does not use the second wireless communication line W2, the flight range of the flight device 2 is the steering device. It is limited to within a predetermined distance from 1. Therefore, the flight control unit 264 acquires the flight start position at which the flight was started and the current position 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 showing 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 wireless control signal generation unit 31, a first wireless control signal output unit 32, and a second wireless control signal output unit 33. The wireless control signal generation unit 31 generates the first wireless control signal and the second wireless control signal based on the selection received by the operation reception unit 162. The first wireless control signal is a signal instructing the flight device 2 to use or not to use the first wireless communication channel W1 in communication of flight data and non-flight data received by the operation receiving unit 162 on the selection screen. The second wireless control signal is a signal instructing the flight device 2 to use or not to use the second wireless communication line W2 in communication of flight data and non-flight data.

  The first wireless control signal output unit 32 causes the communication unit 13 to transmit the first wireless control signal to the flight device 2 using the second wireless communication line W2. For communication of both flight data and non-flight data, when the first wireless communication line W1 is not used, the communication unit 13 of the flight device 2 does not receive the first wireless communication line W1. In this case, the first wireless control signal output unit 32 can not transmit, via the first wireless communication line W1, a control signal for switching the presence or absence of use of the first wireless communication line W1. Therefore, the first wireless control signal output unit 32 transmits the first wireless control signal using the second wireless communication line W2 instead of the first wireless communication line W1. Similarly, the second wireless control signal output unit 33 causes the communication unit 13 to transmit a second wireless control signal to the flight device 2 using the first wireless communication channel W1.

  By adopting such a configuration, the user selects, on the selection screen, a wireless communication line 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, the user who wants to improve the responsiveness of the maneuver can suppress the delay of the control signal by using the first wireless communication channel not passing through the base station 3 of the mobile phone network. On the other hand, the user who places importance on the stability of the wireless communication line improves the stability of the communication between the control device 1 and the flight device 2 by using the second wireless communication line passing through the base station 3 of the mobile phone network. It can be done. Therefore, the user can select a wireless communication line according to the needs.

[Radio wave intensity map]
FIG. 6 shows an example of the operation of the control device 1. In FIG. 6, distribution information indicating a distribution of communication quality of the second wireless communication line W2 for each area is displayed as a radio wave strength map B1. As indicated by hatching label B2, the radio wave intensity map B1 is divided into areas with different radio wave intensities of the second wireless communication line, with different hatchings. Also, the radio wave intensity map B1 is displayed in association with the altitude of the flight device 2 from the ground, and the radio wave intensity map B1 at around 35 m in altitude is shown on this display screen. Every time the user selects the button B3, a radio wave intensity map in which the altitude is increased by 5 m is displayed. Also, every time the user selects the button B4, a radio wave intensity map in which the altitude is decreased by 5 m is displayed. An icon B5 at the center of the radio wave intensity map B1 indicates the flight position and height of the flight device 2. In this display screen, the flight 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 capacity of the control device 1 and the flight device 2, respectively, and pictograms B8 and B9 at the left end and the right end of the display screen Indicates the radio wave intensity. The azimuth magnetic needle B10 indicates the direction in the radio wave intensity map B1, the scale bar B11 indicates the scale of the radio wave intensity map B1, and one scale in the scale bar B11 indicates 100 m.

  The frequencies that can be used by the communication units 13 and 23 of the control device 1 and the flight device 2 differ depending on the model numbers and types of communication modules and SIM cards mounted on the control device 1 and the flight device 2. Therefore, the base station selects available frequency bands in the control device 1 and the flight device 2 based on the model numbers and types of the communication modules of the control device 1 and the flight device 2 and the SIM card. The display control unit 161 of the control device 1 displays a radio wave intensity map corresponding to the frequency band selected by the base station. The user can improve the operability of the flight device 2 by flying the flight device 2 so as to pass through the area where the radio wave intensity is high with reference to the radio wave intensity map B1.

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

  First, the control information generation unit 163 acquires the current position of the flight device 2 by the wireless communication channel by the GPS mounted on the flight device 2 (S11). Next, the display control unit 161 reads out distribution information of communication quality of LTE from the storage unit 14 (S12). The communication unit 13 measures the communication quality of Wi-Fi (S13). Furthermore, the combination recommended by the user for the use of the first wireless communication line W1 and the second wireless communication line W2 for each of the first wireless communication line W1 and the second wireless communication line W2 is displayed by the display control unit 161. Are determined (S14).

  When the combination determined by the display control unit 161 has been changed from the combination of the use and non-use of each of the LTE and Wi-Fi wireless communication lines before the recommendation setting display process is started (YES in S15), display The control unit 161 displays the combination determined by the display control unit 161 on the selection screen (S16). In this selection screen, the user selects whether or not to use the first wireless communication line W1 and the second wireless communication line W2. On the other hand, in step S15, if 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 channel selection process of step S14 of FIG. First, the display control unit 161 compares the field intensity of Wi-Fi with a threshold (S21). The threshold is, for example, a value that does not hinder the operation of the flight device 2 by communication of flight data via Wi-Fi. When the field intensity of Wi-Fi 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 for the user displayed on the selection screen. Is determined to be displayed as a state to use (S22). Next, the display control unit 161 compares the radio wave intensity of LTE with a threshold (S23). The threshold is, for example, a value that does not hinder the operation of the flight device 2 by communication of flight data via LTE. When the radio field strength of LTE is larger 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 for the user displayed on the selection screen Is determined to be displayed, and the process ends (S24).

Therefore, the user can select a wireless communication line according to the needs.

  In addition, when the user selects the use or non-use of the first wireless communication line W1 and the second wireless communication line W2, the display control unit 161 determines the wireless communication line based on the communication quality of the second wireless communication line W2. A combination of use and non-use can be recommended. Therefore, the user can select the presence / absence of use of the wireless communication line with reference to the recommended combination, which can facilitate selection of the user. In addition, when the user selects any of the wireless communication lines including the second wireless communication line W2, the display control unit 161 performs wireless communication based on distribution information on available frequencies of the second wireless communication line W2. A combination of use and nonuse of the line can be recommended. Therefore, the user can select the presence / absence of use of the wireless communication line with reference to the recommended combination, which can further facilitate the user's selection.

  In addition, when a user operation to select not to use any of the first wireless communication line W1 and the second wireless communication line W2 for communication of flight data on the selection screen is performed, the control information generation unit 163 generates a notification unit Output an error by 20. For this reason, it becomes possible to prevent the communication of the flight data from being performed due to the user's erroneous operation, and to prevent the flight device 2 from being steered.

  In addition, when the first wireless communication line W1 is usable and the first wireless communication line W1 is not used for communication of flight data, the display control unit 161 communicates the flight data on the selection screen. In contrast, since the first wireless communication line W1 is displayed as being used, the display control unit 161 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 the predetermined time has elapsed since the flight data or the non-flight data is transmitted using the first wireless communication line W1, display is performed. The control unit 161 causes the selection screen to be displayed as a state in which the second wireless communication line W2 is used for transmission of flight data and non-flight data, so that the communication quality of the first wireless communication line W1 is not good. It can be recommended to the user to change the wireless communication line to the second wireless communication line W2.

  In addition, the first wireless control signal instructing the use of the first wireless communication line W1 is output to the flight device via the second wireless communication line W2, and the second wireless control signal instructing the use of the second wireless communication line W2 is provided. By outputting the control signal to the flying device through the first wireless communication line W1, use or non-use of one wireless communication line is performed in an area where both of the two wireless communication lines can be used.

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

  First, the user creates a flight route of the flight device 2 using the steering device 1. The flight route is a route on which the flight device 2 flies. For example, the user creates a flight route by designating on the map two or more coordinates through which the flight device 2 passes on the display unit 11 of the control device 1. In addition, the flight system S of the present embodiment further includes a server connected to the control device 1 through the second wireless communication line W2, and the communication control unit 164 performs a flight created in advance by the second wireless communication line W2. The route is transmitted to the server by the communication unit 13, and the server stores the flight route. By doing this, the control device 1 does not have to increase the storage capacity of the storage unit 14 for storing a large number of flight routes.

  The operation reception unit 162 of the control device 1 receives a user operation for selecting any one of the flight routes stored in the server before the flight of the flight device 2, and the communication control unit 164 selects the flight selected by the user. A request for transmission of a route is transmitted to the server by the communication unit 13. In response to the 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. Furthermore, the communication control unit 164 causes the flight 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 flight device 2 so that the flight device 2 flies along the flight route, and the communication control unit 164 transmits the control information to the flight device 2. And causing the communication unit 13 to transmit flight data including the generated control information.

[Flowchart Related to Operation of Control Device 1]
FIG. 9 is a flow chart showing an example of the operation of the control device 1 of the present embodiment, in which an example of the recommended setting display process is shown. This process is started, for example, when the control device 1 is connected to the server by 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 procedure as that of FIG.

  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 distribution information of communication quality of LTE in the area including the selected flight route from the storage unit 14 (S32). After acquiring the distribution information of the communication quality of Wi-Fi (S13), the display control unit 161 refers to the distribution information of the LTE and determines whether the communication quality of LTE in the frequency band selected by the base station is good or not (S34).

  FIG. 10 is a flowchart showing an example of the wireless communication channel selection process of step S34 of FIG. First, the display control unit 161 compares the radio wave height of LTE selected by the base station with a threshold (S41). Next, when the radio wave intensity of LTE is larger than the threshold (YES in S41), the display control unit 161 causes the communication recommended for the user to be displayed as a state that uses LTE for communication of flight data and non-flight data. It decides that (S42). Furthermore, the display control unit 161 compares the field intensity of Wi-Fi with a threshold (S43). If the radio wave intensity of Wi-Fi is larger than the threshold, the display control unit 161 determines to display Wi-Fi as a state for communication of flight data and non-flight data in the combination recommended by the user. , End the process (S44).

  When the radio wave intensity of LTE is equal to or less than the threshold in step S41 (NO in S41), display control unit 161 displays a state not using LTE for communication of flight data and non-flight data in the combination recommended by the user. It is decided to let it go (S45). Further, it is determined to display Wi-Fi in communication of flight data and non-flight data in a combination recommended by the user, and the process is ended (S46). In addition, when the field intensity of Wi-Fi is equal to or less than the threshold in step S43, the display control unit 161 does not use Wi-Fi for communication of flight data and non-flight data in a combination recommended by the user. It is determined to be displayed, and the process is ended (S47).

[Effects of Control Device 1 of Second Embodiment]

With such a configuration, the user can select the presence or absence of the use of the first wireless communication line W1 and the second wireless communication line W2 with reference to the recommended combination based on the distribution state, Selection of the presence or absence can be facilitated.

  Further, when the radio wave intensity included in the communication quality of the second wireless communication line is lower than the threshold, the display control unit 161 displays the state that the first wireless communication line W1 is used for communication of flight data. Since the display screen is displayed on the selection screen 11, when the communication quality of the second wireless communication line is not good, it is possible to recommend the user to change the wireless communication line to the first wireless communication line W1.

  The display control unit 161 may be configured to display the radio wave intensity map B1 of FIG. 6 before or at the time of selecting the flight route of the user. By adopting such a configuration, the user refers to the radio field strength map B1 and confirms the area in which the communication state of the second wireless communication line W2 is good, thereby selecting a flight route in which the communication state is good. 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 the communication of the control device 1 and the flight device 2 , The convenience is great.

  In the first and second embodiments of the present invention, an example in which the first wireless communication line W1 and the second wireless communication line W2 having good communication quality are used has been described. However, the present invention is not limited to this, and for example, when both the first wireless communication line W1 and the second wireless communication line W2 are usable, they are used to communicate flight data and non-flight data. Different wireless communication channels may be used. For example, in the state before the user's selection on the selection screen, the display control unit 161 uses the first wireless communication line W1 for communication of flight data, and uses the second wireless communication line W2 for communication of non-flight data. It may be configured to display the use on the display unit 11. By adopting such a configuration, the amount of data to be communicated to two wireless communication lines is dispersed, so that the communication speed in the first wireless communication line W1 is temporarily reduced due to a cross of the wireless communication lines, etc. In this case as well, delay in communication of flight data can be suppressed.

  Further, in the present embodiment, the display control unit 161 of the control device 1 compares the flight route with the distribution information of LTE to determine whether the communication quality of LTE selected by the base station is good or not. Explained. However, the present invention is not limited to the configuration in which the display control unit 161 determines whether the communication quality of LTE is good or not. For example, the server where the flight route is stored determines whether the communication quality of LTE selected by the base station is good or not, and the communication control unit 164 of the control device 1 communicates the flight data and the non-flight data. The server may be notified of the combination of wireless communication lines recommended for the user.

  Moreover, although Embodiment 1 and 2 of this invention demonstrated the structure which receives the user operation which selects a radio | wireless communication circuit in the steering apparatus 1, this invention is not limited to this. For example, a terminal device such as a PC (Personal Computer) may be configured to receive a user operation for selecting a wireless communication channel used in communication between the control device 1 and the flight device 2.

  In the first and second embodiments of the present invention, the configuration has been described in which storage unit 14 holds distribution information indicating the distribution of communication quality of second wireless communication channel W2 for each area. Is not limited to the configuration that holds distribution information. For example, the communication control unit 164 may be configured to obtain distribution information from the server using a wireless communication channel.
