In some embodiments, referring to FIG. 3 , the base station 100 includes a landing platform assembly 110 and/or a hatch assembly 120 .

The take-off and landing platform assembly 110 is used for the take-off and landing of the UAV 200. The take-off and landing platform assembly 110 includes a take-off and landing platform 111. The UAV 200 can land on the take-off and landing platform 111 or take off from the take-off and landing platform 111. Optionally, the take-off and landing platform assembly 110 also includes a push rod assembly 112, which is connected to the take-off and landing platform 111; when opened, the push rod assembly 112 pushes the take-off and landing platform 111 to a preset position for the drone to 200 takes off, and when closing, the landing platform 111 is retracted from the preset position so that the hatch assembly 120 is closed.

Optionally, the hatch assembly 120 is used to provide the accommodation space 101 for the drone 200 . When the hatch cover assembly 120 is closed, the accommodation space 101 is in a closed state at least at the top; when the hatch cover assembly 120 is opened, the accommodation space 101 is in an open state for the UAV 200 to fly out.

Optionally, the hatch cover assembly 120 includes a hatch cover 121 and a movement component 122. The movement component 122 is used to open the hatch cover 121 to make the accommodation space 101 in an open state, or to close the hatch cover 121 to make the accommodation space 101 at least at the top. In a closed state.

For example, the UAV 200 may be a rotary-wing UAV, such as a four-rotor UAV, a six-rotor UAV, an eight-rotor UAV, or a fixed-wing UAV.

Furthermore, data can be transmitted between the base station 100 and the drone 200 through a wireless channel. Specifically, the UAV 200 transmits data with the base station 100 through a wireless channel at least from the time of takeoff to the time of landing. Optionally, after landing on the base station 100, the UAV 200 can be connected to the base station 100 by wire, for example, through a leaf spring connection for data transmission and/or power transmission.

For example, as shown in Figure 2, the wireless channel from the drone 200 to the base station 100 is called the downlink channel, which is used to transmit data collected during the operation of the drone 200, such as videos, pictures, sensor data, and Telemetry data such as status information (OSD) of the drone 200.

For example, as shown in Figure 2, the wireless channel from the base station 100 to the drone 200 is called the uplink channel, which is used to transmit the status of the base station 100, the mission information of the drone 200, and the control of the drone 200. At least one of the instructions.

For the convenience of explanation, the embodiments of this application are mainly explained by applying the control method to the base station.

As shown in Figure 1, the UAV control method according to the embodiment of the present application includes steps S110 to S120.

S110. Obtain the status of the base station. The base station provides accommodating space for the UAV and for the UAV to take off and land.

In some embodiments, the status of the base station may include at least one of the following: the status of the push rod assembly, the status of the hatch assembly, the status of the communication link between the base station and the drone, and the communication link between the base station and the terminal device or server. status, the status of the base station charging the drone, and the environmental information of the location of the base station. Of course, it is not limited to this.

Among them, the status of the push rod assembly includes an open state and a closed state, and the status of the hatch cover assembly includes an open state and a closed state; environmental information about the location of the base station can be obtained, for example, through sensors mounted on the base station, such as wind speed/wind direction sensors and raindrop sensors. , or it can also be obtained from a server, such as a weather server, of course, it is not limited to this.

S120. When the status of the base station meets the preset abnormal conditions, control the drone to perform security policy tasks according to the preset security policy.

Specifically, different abnormal conditions correspond to different security strategies to control the drone according to the status of the base station to improve the security of the drone system and reduce the user's workload.

In some embodiments, when the UAV performs a work task, and when the status of the base station meets a preset abnormal condition, the UAV is controlled to perform a security policy task according to a preset security policy. The unmanned aerial vehicle performs preset tasks, including tasks performed after the unmanned aerial vehicle flies away from the base station and returns to the base station. When the drone is performing an operation task, the drone can be interrupted to perform the operation task according to the status of the base station, and the drone can be controlled to perform security policy tasks, which can improve the safety of the drone.

For example, the terminal device can obtain the operation task information such as the route plan created by the user, and send the operation task information created by the user to the server, and the server sends the operation task information to the base station. Optionally, the server can also check whether the job task information created by the user is reasonable, such as take-off altitude, estimated task execution time, job time interval, etc. When it is unreasonable, it can remind the user and give specific opinions; and Reasonable job task information is sent to the base station. Optionally, the server sends the operation task information to the base station according to the task execution time, so that the base station sends the route plan and other operation task information to the drone at the appropriate time, and opens the push rod assembly and hatch assembly; the drone Take off and execute operation tasks based on operation task information.

Exemplarily, when the UAV performs a work task, and when the status of the base station meets a preset abnormal condition, the UAV is controlled to perform a return mission. By controlling the return of the drone, the drone can be prevented from being in danger or entering an uncontrollable state when performing tasks due to abnormalities in the base station.

For example, the base station can send a return command to the drone when it determines that the status of the base station meets the preset abnormal conditions. The return command, for example, includes the location information of the base station; the drone can autonomously fly after receiving the return command. Returns the location of the base station. Of course, it is not limited to this. For example, the return command may also include the location of an alternate landing point such as another base station. When the UAV receives the return command, it can fly autonomously to the alternate landing point.

Optionally, when the UAV performs a work task, and when the status of the base station affects the UAV's performance of the work task, the UAV is controlled to perform a return mission.

For example, several states that affect the execution of the task by the UAV are preset, and the current state of the base station is compared with the preset state to determine whether the current state of the base station affects the execution of the UAV. The job tasks. For example, the status that affects the execution of different job tasks can be the same or different, and can be set for different job tasks.

Optionally, when the UAV performs a work task and the status of the base station meets the preset abnormal conditions, but the status of the base station does not affect the UAV's performance of the work task, all the UAVs can be controlled. The UAV continues to perform the operation task, and the UAV can return after completing the operation task.

Exemplarily, when the drone performs a work task, and when the base station is restarted or a process of the base station is restarted, the drone is controlled to perform the security policy task according to a preset security policy. In order to prevent the control instructions from being reliably sent to the UAV when the base station is restarted or the process of the base station is restarted, the UAV can be controlled to perform security policy tasks when the base station is preparing to restart or the process of the base station is preparing to restart, such as controlling The drone returns; or the drone can also be controlled to return at a certain stage when the base station is restarted or the process of the base station is restarted.

Exemplarily, when the drone performs a task and the environmental conditions within the preset range of the base station meet the preset abnormal conditions, the drone is controlled to execute the security policy according to the preset security policy. Task. For example, when the weather near the base station will suddenly change or has suddenly changed to strong winds and heavy rain, the drone is controlled to perform safety policy tasks, such as controlling the drone to return home in time.

In some embodiments, when the status of the base station meets a preset abnormal condition, controlling the drone to perform a security policy task according to a preset security policy includes: when the drone performs a return mission. , and when the status of the base station meets the preset abnormal conditions, the drone is controlled to land on the hatch assembly of the base station, or the drone is controlled to land at an alternate landing point.

For example, when the status of the base station meets some abnormal conditions, the drone cannot land safely to the base station, such as when the accommodation space of the base station cannot be opened, or cannot be closed after being opened, or the environment near the base station In bad weather, the drone can be controlled to land at an alternate landing point.

For example, when the accommodation space of the base station cannot be opened, the drone can also be controlled to land on the hatch assembly of the base station. For example, when the battery of the drone is low and cannot guarantee the flight to the alternate landing point, it can land on the hatch assembly of the base station. For example, when the accommodation space of the base station cannot be opened and the weather environment near the base station is good, the drone can be controlled to land on the hatch assembly of the base station.

For example, when the UAV performs a return mission and the base station fails to control the push rod assembly to open and/or the hatch assembly to open, the UAV is controlled to land on the hatch assembly of the base station. or control the drone to land at an alternate landing point. When the push rod assembly and/or the motion assembly of the base station fails, the accommodation space of the base station cannot be opened to the drone, and the drone can land on the hatch assembly of the base station.

For example, when controlling the UAV to land on the hatch assembly of the base station, the UAV is also controlled to reduce the rotation speed of the motor in the power assembly. It can be understood that the descending speed of the UAV when landing on the hatch assembly of the base station is smaller than the speed of landing on the take-off and landing platform of the base station. It can make the drone land to the hatch cover assembly at a lower speed, reducing the mechanical impact on the base station and the drone.

Optionally, when the drone returns, if the base station fails to control the push rod assembly and/or the hatch assembly to open, the base station can be controlled to restart; the drone returns to the hatch assembly of the base station. After the base station restarts, the drone takes off to a preset height, and the base station then controls the push rod assembly and hatch assembly to open. If they can be opened, the drone can be controlled to land on the take-off and landing platform of the base station.

Exemplarily, when the UAV performs a return mission, and when the status of the base station meets a preset abnormal condition, the UAV is controlled to land on the hatch assembly of the base station, or the UAV is controlled to land on the hatch assembly of the base station. Landing the UAV to an alternate landing point includes: performing a return mission on the UAV, and controlling the UAV to hover when the status of the base station meets preset abnormal conditions; When the power of the drone is lower than the preset threshold, the drone is controlled to land on the hatch assembly of the base station, or the drone is controlled to land at an alternate landing point.

When the status of the base station meets the preset abnormal conditions, the drone is controlled to hover above or near the base station; after waiting for the status of the base station to return to abnormality, it can land on the landing platform of the base station; of course, it is not limited to this, for example When the status of the base station meets the preset abnormal conditions, the drone can be controlled to land on the take-off and landing platform of the base station without waiting when it reaches above or near the base station, or the drone can be controlled to land directly to the alternate landing point. For example, when the UAV performs a return mission and the status of the base station meets preset abnormal conditions, the UAV is controlled to return to above or near the base station and then hover, and the UAV is controlled to hover above or near the base station. The base station restarts; after the base station restarts, the push rod assembly and the hatch assembly are controlled to open. If they can be opened, the drone can be controlled to land on the take-off and landing platform of the base station.

When the power of the drone is lower than the preset threshold and the base station still fails to control the opening of the push rod assembly and/or the opening of the hatch assembly, the drone is controlled to land on the hatch assembly of the base station, Or control the drone to land at an alternate landing point.

In some embodiments, when the status of the base station meets a preset abnormal condition, controlling the drone to perform a security policy task according to a preset security policy includes: when the drone lands at the location The base station, and when the base station fails to control the push rod assembly to retract and/or the hatch assembly to close, control the UAV to take off from the base station and land to the alternate landing point. When the base station lands on the take-off and landing platform of the base station, but the base station fails to control the retraction of the push rod assembly and/or the closing of the hatch assembly, in order to prevent the UAV from being exposed to risks such as rain, the UAV can be controlled The aircraft takes off from the base station and lands at the alternate landing point.

In some embodiments, when the status of the base station meets a preset abnormal condition, controlling the UAV to perform a security policy task according to a preset security policy includes: when the base station interacts with the UAV When the communication link of the drone is disconnected, the drone is controlled to restart and/or link with the base station. After the UAV is restarted, it can also be linked to the base station. Through restarting and/or frequency linking, there is a high probability that the communication link between the base station and the UAV can be restored. Of course, it is not limited to this. Alternatively, when the communication link between the base station and the drone is disconnected, the base station can be controlled to restart and/or be frequency-linked with the drone.

For example, when it is determined that the communication link between the base station and the UAV is disconnected before the UAV has taken off from the take-off and landing platform of the base station, the UAV is controlled to restart and/or Link to the base station. After the UAV flies away from the take-off and landing platform of the base station, when it is determined that the communication link between the base station and the UAV is disconnected, the base station can be controlled to restart and/or be frequency-linked with the UAV.

In some embodiments, controlling the drone to perform security policy tasks according to a preset security policy includes: sending fault information corresponding to the abnormal condition to a terminal device so that the terminal device outputs the fault information. ; Acquire the control instructions sent by the terminal device according to the user's troubleshooting operation, and control the drone to perform security policy tasks according to the control instructions. Users can control the drone through the base station through the terminal device, and can handle faults remotely in a timely manner without going to the site for treatment.

Exemplarily, sending the fault information corresponding to the abnormal condition to the terminal device includes: sending the fault information corresponding to the abnormal condition and corresponding troubleshooting prompt information to the terminal device, and the troubleshooting prompt information is used to prompt The user performs corresponding troubleshooting operations. For example, the display device of the terminal device provides a debugging interface. The debugging interface is used to output the fault information. It can also be used to output troubleshooting prompt information corresponding to the fault information. The troubleshooting prompt information can prompt the user. Recommended UAV security policy tasks, optionally, this debugging interface can be called a remote troubleshooting interface; the user can perform troubleshooting operations according to the operation prompts, so that the terminal device sends control instructions to the base station, and the base station controls according to the The instructions control the drone to perform corresponding security policy tasks.

In some embodiments, when the status of the base station meets preset abnormal conditions, such as when the base station fails to control the opening of the push rod assembly and/or the opening of the hatch assembly, fault information corresponding to the abnormal conditions is sent to the terminal device. and corresponding troubleshooting prompt information. The troubleshooting prompt information is used to prompt the user to troubleshoot the corresponding base station, such as controlling the shutdown and restart of the base station, or controlling the opening/closing of the push rod assembly of the base station, or controlling the hatch cover of the base station. The component is turned on or off.

In some embodiments, the status of the UAV and/or the status of the base station can be obtained, and whether the status of the base station meets the predetermined status is determined based on the status of the UAV and/or the status of the base station. Set troubleshooting conditions. When it is determined that the status of the base station meets the preset abnormal conditions, fault information is sent to the terminal device so that the terminal device prompts the user to perform troubleshooting operations based on the fault information; and based on the user's troubleshooting operations, controls all The drone and/or the base station perform preset troubleshooting tasks.

For example, when the status of the base station meets a preset abnormal condition, the base station can be controlled to perform a preset troubleshooting task. For example, when it is determined that a first preset fault occurs in the base station according to the status of the drone and/or the status of the base station, the first fault information is sent to the terminal device so that the user can Control the base station to perform the first troubleshooting task.

For example, when it is determined that the first functional component of the base station is faulty, first fault information is sent to the terminal device, and the user can control the base station to perform at least one of the following first troubleshooting tasks based on the first fault information: Restart and control the first functional component to adjust its working state. Optionally, the first functional component of the base station includes at least one of the following: push rod assembly, hatch cover assembly, charging assembly, switch assembly, connection assembly, blade storage assembly, and positioning assembly; wherein the push rod assembly The hatch assembly is used to push the take-off and landing platform to a preset position, the hatch assembly is used to provide a receiving space for the drone, the charging assembly is used to charge the drone, and the switch assembly is used to Triggering the startup or shutdown of the UAV, the connecting component is used to electrically connect with the UAV, the blade storage component is used to store the blades of the UAV, and the positioning component is used to obtain The location of the base station.

For example, when it is determined that the push rod assembly and/or the hatch assembly of the base station are faulty before the UAV has taken off from the base station, the first fault information is sent to the terminal device so that the user can perform the operation according to the The first fault information controls the base station to restart, or controls the push rod assembly of the base station to close (retract from the preset position) and/or the hatch assembly to close.

For example, when it is determined that the base station fails to meet the take-off preparation conditions, first fault information is sent to the terminal device so that the user controls the base station to retract the push rod assembly and/or shut down according to the first fault information. The hatch cover assembly.

For example, the failure of the base station to meet the take-off preparation conditions includes at least one of the following: the base station has not obtained the flight control rights of the UAV, the base station has not obtained the route information, or the obtained route information has been verified.
