<Outline of Embodiment>
FIG. 1 is a diagram schematically illustrating an overall configuration of a communication system S according to an embodiment. The communication system S includes a communication device 1 and a flying device 2. The communication device 1 and the flying device 2 are paired with each other, and can communicate with each other via the wireless network N. FIG. 1 illustrates an example in which the communication device 1 is a control device and the communication destination device 2 is a device that can be controlled by a user using the communication device 1. In particular, FIG. 1 shows an example in which the communication destination device 2 is a flying device such as a drone.

  The communication device 1 is a communication terminal such as a smartphone and a tablet. When the communication destination device 2 is a flying device, the communication device 1 may be a dedicated radio for operating the communication destination device 2. Hereinafter, in this specification, it is assumed that the communication destination device 2 is a flying device, and is described as “flying device 2” for convenience. However, the communication destination device 2 is not limited to a flight device. Like the communication device 1, the communication destination device 2 may be a communication terminal such as a smartphone or a tablet.

  When the user operates the communication device 1, the communication device 1 transmits control information corresponding to the operation content to the flying device 2. The flight device 2 transmits to the communication device 1 flight information necessary for maneuvering, such as a flight position and a flight speed. Further, the flying device 2 has a camera, and transmits image data generated by imaging with the camera to the communication device 1.

  The communication device 1 and the flight device 2 can transmit and receive control information, flight information, and image data using a plurality of wireless communication lines. The communication device 1 and the flying device 2 communicate using a first wireless communication line W1 capable of transmitting and receiving information without passing through a base station 3 of a mobile phone network. The communication device 1 and the flight device 2 can also communicate using a second wireless communication line W2 capable of transmitting and receiving information via a base station 3 of a mobile phone network. In particular, when the communication device 1 and the flying device 2 are far apart, the communication device 1 and the flying device 2 communicate with each other using the second wireless communication line W2. The first wireless communication line W1 is, for example, a Wi-Fi (registered trademark) line. The second wireless communication line W2 is, for example, a 4G (4th Generation) line including LTE (Long Time Evolution).

  Generally, a communication device is equipped with a function of displaying an indicator indicating the communication quality around its own device including the radio wave intensity of the wireless network N. The communication device 1 and the flying device 2 have the same function, and each has a function of displaying an indicator indicating the communication quality of the wireless network N in a peripheral area including the own device.

  By the way, in the communication system S according to the embodiment, the flying device 2 flies according to the flight information received from the communication device 1 via the wireless network N. For this reason, when the communication quality around the flying device 2 is degraded, it may happen that the communication device 1 cannot control the flight of the flying device 2. When the communication quality of the periphery of the flying device 2 cannot be acquired from the communication device 1 when the flying device 2 is made to fly to a place away from the communication device 1, the flying device 2 moves to an area having poor communication quality and the control by the user is not performed. It can be difficult.

  Therefore, the communication device 1 according to the embodiment acquires the communication quality of the wireless network N around the flying device 2 from the flying device 2 while the communication with the flying device 2 is possible. Therefore, the communication device 1 can display an indicator indicating the communication quality of the wireless network N around the flying device 2 in addition to or instead of the indicator indicating the communication quality of the wireless network N around the own device. . Thereby, the user who operates the communication device 1 according to the embodiment can check the communication quality of the wireless network N around the flying device 2 using the communication device 1 at hand.

Hereinafter, the functional configuration of the communication device 1 will be described in more detail.
<Functional Configuration of Communication Device 1>
FIG. 2 is a diagram schematically illustrating a functional configuration of the communication device 1 according to the embodiment. The communication device 1 according to the embodiment includes a communication unit 10, a storage unit 20, a display unit 30, an operation unit 40, a quality information acquisition unit 50, a control unit 60, and a notification unit 70.

  The communication unit 10 is a communication interface for the communication device 1 to transmit and receive information to and from the flying device 2. The communication unit 10 includes a reception unit 11 and a transmission unit 12. The communication unit 10 is realized by a known communication module such as a Wi-Fi (registered trademark) module or a mobile phone communication module.

  The storage unit 20 includes a ROM (Read Only Memory) for storing an OS (Operating System) and application programs, a RAM (Random Access Memory) as a work area of the communication device 1, and an SSD (Solid State) for storing various other information. Drive).

  The display unit 30 is an interface for visually notifying a user of information generated by the communication device 1. The display unit 30 may be a touch screen in which a display area and a touch panel are integrated, and in this case, the display unit 30 also functions as an input interface.

  The operation unit 40 is a device for a user to perform an operation for operating the flying device 2. The operation unit 40 includes, for example, a joystick or a volume for controlling a flight direction and a flight speed. When the display unit 30 is a touch screen, the operation unit 40 may be entirely or partially implemented using a GUI (Graphical User Interface) displayed on the display unit 30.

  The quality information acquisition unit 50 acquires quality information indicating the communication quality of the wireless network N at the location where the communication device 1 exists. Here, the “communication quality of the wireless network N” includes not only the radio wave intensity of the wireless network N but also the radio wave interference. For example, when the radio wave intensity of the wireless network N becomes weak, the communication quality is reduced. Further, when the radio wave interference of the wireless network N is large, the communication quality of the wireless network N is deteriorated even when the radio wave intensity of the wireless network N is strong.

The control unit 60 is a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) of the communication device 1, and executes a program stored in the storage unit 20 to execute the communication control unit 61 and the display control unit 62. , A distribution information acquisition unit 63 and an operation reception unit 64 that converts an input of the operation unit 40 into operation information of the flying device 2.
The notification unit 70 will be described later.

  The communication control unit 61 controls the operation of the communication unit 10. The communication control unit 61 controls the receiving unit 11 to receive information from outside the communication device 1, and controls the transmission unit 12 to transmit information to the outside of the communication device 1. For example, under the control of the communication control unit 61, the receiving unit 11 receives, from the flying device 2, quality information indicating the communication quality of the wireless network N at a place where the flying device 2 with which the communication device 1 is communicating is present. The transmission unit 12 transmits a control signal used for maneuvering the flying device 2 to the flying device 2 via the wireless network N under the control of the communication control unit 61.

  Hereinafter, in this specification, the description of the communication control unit 61 is omitted on the assumption that the reception unit 11 and the transmission unit 12 operate under the control of the communication control unit 61. For convenience of description, the quality information indicating the communication quality of the wireless network N at the place where the flying device 2 with which the communication device 1 is communicating exists is referred to as “first quality information”. Similarly, quality information indicating the communication quality of the wireless network N at the location where the communication device 1 exists is referred to as “second quality information”.

  The display control unit 62 controls the display operation of the display unit 30. For example, the display control unit 62 causes the display unit of the display unit 30 to display the first quality information and the second quality information.

  FIG. 3 is a diagram schematically illustrating an example of a display screen displayed on the display unit 30 of the communication device 1 according to the embodiment. In the example illustrated in FIG. 3, the display screen includes a first quality information indicator 301, a second quality information indicator 302, a communication destination icon 303, an own device icon 304, a communication destination battery remaining amount indicator 305, an own device battery remaining amount indicator 306, An information panel 307, a route map 308, and a live image display area 309 are included.

  The first quality information indicator 301 is an icon indicating the first quality information, and the second quality information indicator 302 is an icon indicating the second quality information. As illustrated in FIG. 3, the display control unit 62 causes the first quality information indicator 301 to display the first quality information indicator 301 near the communication destination icon 303 indicating the flying device 2 that is the communication destination device. Similarly, the display control unit 62 causes the second quality information indicator 302 to be displayed near the own device icon 304 indicating the communication device 1. Thereby, the user of the communication device 1 can grasp the communication quality around the communication device 1 and the communication quality around the flying device 2 at a glance of the display unit 30.

  The display control unit 62 displays a communication destination battery remaining amount indicator 305 indicating the remaining amount of the battery of the flying device 2 near the communication destination icon 303. The display control unit 62 also displays an own battery level indicator 306 indicating the remaining battery level of the communication device 1 near the own device icon 304. Thereby, the user of the communication device 1 can grasp the battery remaining amount of the communication device 1 and the battery remaining amount of the flying device 2 at a glance of the display unit 30. In the case where the user controls the flying device 2 in the distance using the communication device 1, if the battery of the flying device 2 runs out and the operation of the flying device 2 stops, it takes time to collect the flying device 2. By indicating the user with the remaining battery level of the flying device 2, the communication device 1 can provide the user with a notice that the flying device 2 will be returned before the battery of the flying device 2 runs out.

  The display control unit 62 also displays an information panel 307 indicating information related to the flight of the flying device 2 near the communication destination icon 303. The information panel 307 includes an indicator indicating the distance between the communication device 1 and the flying device 2, the flying speed of the flying device 2, the altitude of the flying device 2, and the traveling direction of the flying device 2.

  The display control unit 62 can calculate the distance between the communication device 1 and the flying device 2 by using the respective position information of the communication device 1 and the flying device 2. When the communication device 1 and the flying device 2 are communicating via the first wireless communication line W1, the display control unit 62 estimates the distance between the communication device 1 and the flying device 2 from the difference between the respective radio wave intensities. May be.

  The display control unit 62 also causes the display unit 30 to display a route map 308 that is a two-dimensional map including a start point of the flying device 2 and a destination point of the flying device 2. In the example of the route map 308 illustrated in FIG. 3, the start point of the flying device 2 is indicated by a black circle, and the target point of the flying device 2 is indicated by a white star. In addition, the current position of the flying device 2 on the route map 308 is indicated by a black triangle, and the route from the start point of the flying device 2 to the current position of the flying device 2 is also shown. By checking the information panel 307 and the route map 308, the user can determine the start point of the flying device 2 (that is, the point where the user is located), the current position of the flying device 2, and the destination point of the flying device 2. You can understand the relationship.

  As described above, the flying device 2 has a camera, and the receiving unit 11 receives image data generated by imaging the camera of the flying device 2. The display control unit 62 displays the data received by the receiving unit 11 in the live image display area 309. Thereby, the user can operate the flying device 2 while watching the image around the flying device 2. When the user selects the full screen display icon 310, the display control unit 62 displays the image data generated by the camera of the flying device 2 on the entire display area of the display unit 30. This allows the user to operate the flying device 2 while viewing the live image captured by the camera of the flying device 2 on a wider screen.

  When the display control unit 62 displays the live image captured by the camera of the flying device 2 on a full screen, the user can select whether to superimpose the above-described indicators and icons on the live image. . This is realized by a user operating a setting GUI (not shown).

  Returning to the description of FIG. The notification unit 70 notifies the user when the radio field intensity of the wireless network N included in the first quality information becomes equal to or less than a predetermined threshold. Specifically, when the radio wave intensity around the flying device 2 becomes equal to or less than a predetermined threshold value, the notification unit 70 causes the display unit 30 to display a message indicating the same, via the display control unit 62. The notification unit 70 may vibrate a vibrator (not shown) incorporated in the communication device 1 or generate a sound from a speaker (not shown) of the communication device 1 instead of or in addition to displaying the message on the display unit 30. May be notified to the user.

  Note that the “predetermined threshold value” refers to the value of the radio wave intensity referred to by the notification unit 70 in order to determine whether communication quality that can withstand transmission of operation information from the communication device 1 to the flying device 2 can be maintained. This is a determination reference threshold. The specific value of the determination criterion threshold may be determined by an experiment in consideration of the performance of the antennas included in the communication device 1 and the flying device 2.

  FIG. 4 is a diagram schematically illustrating a display screen displayed on the display unit 30 when the radio wave intensity around the flying device 2 becomes equal to or less than a predetermined threshold. As shown in FIG. 4, when the radio wave intensity around the flying device 2 becomes equal to or less than a predetermined threshold, the display unit 30 displays a radio wave intensity reduction message 311. Thus, the user can move the flying device 2 to an environment with good communication quality before the communication with the flying device 2 is interrupted.

  Here, if it is possible to know in which direction the flying device 2 is moved to improve the communication environment, it is useful for the user. Therefore, the communication device 1 also includes a distribution information acquisition unit 63 that acquires distribution information indicating a distribution of communication quality of the second wireless communication line measured in advance. The display control unit 62 causes the display unit 30 to display a distribution of communication quality indicated by distribution information in an area including the position of the communication device 1 and the position of the flying device 2. The display control unit 62 further causes the display unit 30 to display a direction in which the communication quality indicated by the second quality information is improved when the flying device 2 moves.

  In FIG. 4, a direction indicator 312 indicates a direction in which communication quality indicated by the second quality information improves when the flying device 2 moves, and a user icon 313 indicates the presence of the user based on the position of the flying device 2. Indicates the direction. In the example illustrated in FIG. 4, the communication quality indicated by the second quality information is improved when the user operates the flying device 2 to move in the northwest direction.

  The direction indicator 312 shown in FIG. 4 indicates the direction in which the flying device 2 can actually move. The display control unit 62 may display the direction indicator 312 on the display unit 30 in a direction in which the flying device 2 cannot move due to an obstacle or the like even in a direction in which the communication quality indicated by the second quality information is improved. , An icon (not shown) indicating that it cannot be moved is displayed.

  Here, the flying device 2 stops (hovers) on the spot until new operation information is transmitted from the communication device 1 when the radio wave intensity around the flying device 2 becomes equal to or less than a predetermined threshold value. You may. Thereby, it is possible to prevent the flying device 2 from moving to a region where the radio wave intensity is lower.

  FIG. 5 is a diagram illustrating an example of the radio wave intensity map 314 displayed on the display unit 30. In FIG. 5, distribution information indicating the distribution of the communication quality of the second wireless communication line W2 for each area is displayed as a radio field intensity map 314. In the radio wave intensity map 314, as shown by a hatching label 315, regions having different radio wave intensities of the second wireless communication line are classified by different hatching.

  The radio field intensity map includes three-dimensional distribution information of communication quality. Therefore, the display control unit 62 displays the radio field intensity map 314 in association with the altitude of the flying device 2 from the ground. On this display screen, a radio field intensity map 314 near an altitude of 35 m is shown. Every time the user selects the up icon 316, the display control unit 62 displays a radio field intensity map with the altitude increased by 5 m. Further, each time the user selects the down icon 317, the display control unit 62 displays a radio field intensity map in which the altitude is reduced by 5 m.

  The receiving unit 11 receives information indicating the location of the flying device 2 from the flying device 2 via the wireless network N. The display control unit 62 displays a flight device icon 318 indicating the flight position and height of the flight device 2 in the center of the radio field intensity map 314. This display screen shows an example in which the flying device 2 is located at an altitude of 34.2 m from the ground. As described above, the display control unit 62 causes the display unit 30 to display the location where the flying device 2 is superimposed on the radio field intensity map 314 including the location where the flying device 2 is located. Thereby, the user can fly the flying device 2 by selecting an area with good communication quality.

  The display control unit 62 may read out the radio wave intensity map 314 stored in the storage unit 20 in advance and display the radio wave intensity map 314 on the display unit 30 or may display the radio wave intensity measured by the flying device 2 during the flight on the receiving unit 11. And may be displayed on the display unit 30.

  The flying device 2 may include a distance measuring sensor (not shown). In this case, the flying device 2 measures the distance to an obstacle such as a structure existing in the traveling direction, and imposes a limit on the altitude change of the flying device 2 according to the measurement result, or the user can use the flying device 2 A warning may be issued when an attempt is made to change the altitude.

  FIG. 5 shows the radio field intensity when the flying device 2 is viewed from above. Instead of or in addition to this display, the radio field intensity when the flying device 2 is viewed from the side (that is, when the line of sight is viewed from a direction parallel to the ground) may be displayed. Thereby, the user can easily grasp the distribution of the radio wave intensity in the height direction.

  As described with reference to FIG. 1, the wireless network N includes a path using the first wireless communication line W1 without passing through the base station of the mobile phone network, and a second wireless communication line W2 via the base station of the mobile phone network. And a route using Therefore, it is convenient if the user can confirm the communication quality of each of the first wireless communication line W1 and the second wireless communication line W2. Therefore, the display control unit 62 causes the display unit 30 to display the first quality information and the second quality information for each of the radio wave intensity in the first wireless communication line W1 and the communication quality in the second wireless communication line W2.

  FIG. 6 is a diagram schematically illustrating another example of the display screen displayed on the display unit 30 of the communication device 1 according to the embodiment. The display screen shown in FIG. 6 is similar to the display screen shown in FIG. The display screen shown in FIG. 6 differs from the display screen shown in FIG. 3 in including a third quality information indicator 319 and a fourth quality information indicator 320, but is otherwise the same.

  The third quality information indicator 319 is an indicator that indicates the communication quality of the first wireless communication line W1 around the flying device 2. On the other hand, the fourth quality information indicator 320 is an indicator indicating the communication quality of the first wireless communication line W1 around the communication device 1. As described above, the display control unit 62 displays the respective communication qualities of the first wireless communication line W1 and the second wireless communication line W2 on the display unit 30 for the periphery of the communication device 1 and the periphery of the flying device 2. Let it. Thereby, the user can change the line of the wireless network N used for communication between the communication device 1 and the flying device 2 according to the communication quality.
