Fig. 3 is a schematic flow chart of the UAV forced landing control method provided by the embodiment of the present application. The method can be executed by the above-mentioned remote control device 100 (for example, the controller in the remote control device 100). As shown in Fig. 3, the method includes:

101: When the UAV meets the forced landing condition, determine a forced landing method, where the forced landing method includes landing from the current position and/or landing from a forced landing point.

Among them, the forced landing conditions include a variety of conditions that are not conducive to the safe flight of the UAV, which can be different according to different UAV models and performances, and can be set according to actual application conditions. For example, the battery temperature exceeds a preset temperature threshold, the battery power is lower than a preset power threshold, the tilt angle of the drone exceeds the preset angle threshold, the current wind speed exceeds the preset wind speed threshold, the current position is within a certain range of the no-fly area, and the gimbal Abnormal operation and image transmission operation abnormality, etc.

The embodiment of the present application provides multiple forced landing methods, for example, landing from a current location or from a forced landing point. Land from the current position, that is, start the forced landing with the current position of the UAV as the starting point of the forced landing. Landing from the forced landing point means starting the forced landing with a certain forced landing point as the starting point of the forced landing.

The forced landing point can be a preset forced landing point or a designated forced landing point. The preset forced landing point is a preset forced landing point. There can be one or more preset forced landing points. When there are multiple preset forced landing points, the UAV can choose one of them as the starting point of forced landing . Specify the forced landing point, that is, the forced landing point specified by the user.

Provide a way to land from the forced landing point. When the user chooses the forced landing method from the forced landing point, even if the drone is not within the user's safe and visible range, the correct forced landing point can be selected for forced landing, which can reduce the drone's landing on uneven ground Risk to ground or water.

When the UAV meets the forced landing conditions, a forced landing method needs to be selected.

In one of the embodiments, the drone sends the current flight status (such as drone operation status and environmental conditions, etc.) to the remote control device, and the remote control device displays the current flight status of the drone on its display screen or its coupled display screen. , the user can know the flight status of the drone through the display screen, and judge whether the drone can fly normally. When it is judged that the drone cannot fly normally, the user can manually trigger the drone to make an emergency landing.

The UAV can also directly judge the flight status of the UAV. When it is judged that the UAV meets the conditions for forced landing, the warning information will be sent to the remote control device. After the user views the warning information on the display screen, it can be triggered manually. Drone forced to land.

Specifically, in some embodiments, when the user determines that the drone will not be able to fly normally, the user can trigger the input device of the remote control device (such as triggering a touch button on the touch screen, the triggering includes clicking, long pressing, etc.) operation), to trigger a manual forced landing.

The display screen of the remote control device or its coupled display screen will display each forced landing mode, and the user can perform a second input operation on the remote control device (for example, perform a touch operation on the corresponding forced landing mode option, the touch operation includes click, long press and so on), to choose one of the forced landing methods.

Figure 4 shows a form of determining the forced landing method. In the embodiment shown in Figure 4, when the user determines that the drone meets the forced landing conditions by observing the flight situation of the drone, the forced landing on the touch screen is manually triggered button, and a forced landing method selection menu will pop up, and the user can click on the menu to select the forced landing method.

In the embodiment shown in Figure 4, the forced landing method includes three forced landing methods: landing from the current position, landing from a preset forced landing point and landing from a designated forced landing point. In other embodiments, more or less Forced landing method.

In the above embodiment, the user triggers the remote control device to display the forced landing mode, and the user inputs a second input operation to the remote control device to select the forced landing mode. In other embodiments, the remote control device can also automatically judge whether the UAV meets the forced landing condition according to the flight situation of the UAV. When the forced landing condition is met, the forced landing method is displayed, and the forced landing method of the UAV is selected by the user. .

102: Obtain a forced landing instruction based on the forced landing manner, where the forced landing instruction is used to instruct the UAV to make a forced landing.

If the forced landing method is to land from the current position, the forced landing command is used to instruct the UAV to land from the current position. At this time, the forced landing command may include the forced landing mode of "landing from the current position".

If the forced landing method is to land from the forced landing point, it is also necessary to obtain the forced landing point position, and form a forced landing command based on the forced landing point position. Then, the forced landing command is sent to the UAV, and the UAV can obtain the position of the forced landing point according to the forced landing command, and perform forced landing based on the position of the forced landing point.

If the forced landing method includes landing from a preset forced landing point, at least one corresponding preset forced landing point may be set in advance for each flight path. When landing from a preset forced landing point is selected, the remote control device may acquire at least one corresponding preset forced landing point based on the current flight path of the drone. And select an emergency landing point as the target emergency landing point of the UAV.

Specifically, in some embodiments, the forced landing point closest to the current position of the drone may be selected from at least one preset forced landing point as the target forced landing point.

In some other embodiments, at least one forced landing point may also be carried in the forced landing command by the remote control device, and after the UAV obtains at least one forced landing point in the forced landing command, it selects one of the forced landing points (for example, selects the one closest to its own position) One forced landing point) is used as the target forced landing point, and the forced landing is carried out according to the target forced landing point.

As shown in Figure 5, when the forced landing method is forced landing from the preset forced landing point, three preset forced landing points 1, 2, and 3 corresponding to the flight path are obtained based on the flight path of the drone, and the preset forced landing point is finally confirmed 3 is the target forced landing point, and the position information of the target forced landing point can also be displayed on the right side of the figure, so that the user can understand the position of the target forced landing point.

If the forced landing method is forced landing from a designated forced landing point, at least one forced landing point needs to be specified by the user. The user can temporarily designate an forced landing point as the target forced landing of the drone according to the flight path of the drone, considering various factors such as the destination point.

In one of the embodiments, the user can designate the target forced landing point by performing a first input operation on the remote control device. For example, on the flight route of the drone displayed on the display screen of the remote control device, by performing a touch operation (such as a click operation) on any point in the flight route, this point is the target forced landing point designated by the user.

As shown in FIG. 6 , when the forced landing mode is designated forced landing point, the user specifies forced landing point 1 as the target forced landing point based on the flight path and flight destination of the drone.

In some other embodiments, the forced landing method may also include the forced landing method of the UAV itself. When the UAV encounters a serious failure, if it waits for the emergency landing command from the remote control device, it may miss the best time for emergency landing, resulting in accidents. Therefore, when the UAV encounters a serious failure, it can first implement a self-forced landing strategy.

For example, when the UAV fails or other conditions that are not suitable for flying occur during the flight, first judge whether the situation is serious, and if it is serious, it will not wait for the forced landing command from the remote control device, and perform the forced landing operation by itself. If it is not serious, an alarm message is sent to the remote control device, and the user manually operates the remote control device to perform a manual forced landing. After the UAV receives the forced landing command from the remote control device, it performs a forced landing according to the forced landing command. If the UAV does not receive an emergency landing instruction from the remote control device within a preset time period (for example, within five minutes), it means that the user wants the UAV to make an emergency landing on its own, and at this time the UAV makes an emergency landing on its own.

Fig. 7 shows a specific embodiment of the UAV forced landing control method. When the UAV breaks down during the flight or is otherwise not suitable for flying, it needs to perform a forced landing. The UAV will judge the severity of the current situation. If it is a serious fault, for example, the battery temperature is higher than the maximum temperature threshold, the battery power is lower than the minimum power threshold, the current wind speed is greater than the maximum wind speed threshold, and the current location of the UAV is very far away from the no-fly area. approaching, the UAV's inclination angle exceeds the maximum inclination threshold, etc., the UAV will first execute the forced landing strategy by itself.

If it is not a serious fault, for example, the battery temperature only exceeds an alarm temperature threshold and has not reached the maximum temperature threshold, the drone will send an alarm message to the remote control device, and the remote control device will display the alarm on its display or its coupled display information. The user can decide whether to perform an forced landing manually according to the warning information.

In this embodiment, the manual forced landing includes three ways of forced landing, which are forced landing from the current position, forced landing from a preset forced landing point and forced landing from a specified forced landing point. If the forced landing method is forced landing from a preset forced landing point, the remote control device obtains at least one preset forced landing point corresponding to the flight path based on the current flight path of the drone. If the forced landing method is forced landing at a designated forced landing point, the user must designate a forced landing point as the target forced landing point.

The remote control device generates a forced landing instruction, and if the forced landing method is forced landing from the current position, the forced landing instruction at least includes the forced landing method. If the forced landing method is forced landing from a preset forced landing point, the forced landing instruction may include the forced landing method and at least one preset forced landing point. If the forced landing method is forced landing from a designated forced landing point, the forced landing instruction may include the forced landing method and the target forced landing point specified by the user.

After receiving the forced landing command sent by the remote control device, the UAV performs a forced landing according to the forced landing command. If the forced landing command includes the forced landing method of "forced landing from the current position", the drone will be forced to land from the current position. If the forced landing instruction includes the forced landing method of "forced landing from a preset forced landing point" and at least one preset forced landing point, the UAV selects an forced landing point closest to its own position from at least one preset forced landing point as the target forced landing point, and Forced landing from the target landing point.

If the forced landing instruction includes the forced landing method of "forced landing from the specified forced landing point" and the target forced landing point specified by the user, the UAV is forced to land from the target forced landing point specified by the user.

In some embodiments, if the drone does not receive an emergency landing command from the remote control device after a period of time after the drone sends the warning information to the remote control device, it chooses to make a forced landing by itself.

In addition to the automatic forced landing mode of the drone, the embodiment of the present application also provides a variety of forced landing methods manually controlled by the user. The combination of the automatic forced landing method and a variety of manual forced landing methods improves the safety of the aircraft landing and reduces the occurrence of accidents. Rate.
