Detailed ways

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system such as a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

Referring to FIG. 1, a first embodiment of the present invention provides a method for controlling an unmanned aerial vehicle, including:

Step 100: When the remote control device determines that the working state of the load carried by the UAV is abnormal, the UAV sends a request for acquiring the flight state information of the UAV when the working state of the load is abnormal.

In this step, the remote control device may first establish a two-way communication mechanism with the load, or the load establishes a one-way communication mechanism to the remote control device. When the feedback signal of the load is not received within a predetermined time, it is determined that the working state of the load is abnormal.

When the working state of the load is abnormal (such as power failure, falling off from the unmanned aerial vehicle, etc.), the communication link between the load and the remote control device is interrupted, thereby causing the communication between the load and the remote control device to stop, and therefore, the two-way communication mechanism can be adopted. To determine whether the working state of the load is normal.

For example, a real-time heartbeat is established between the remote control device and the load, that is, the sender periodically sends a heartbeat request to the receiver, and the receiver sends a heartbeat response to the sender within a predetermined time after receiving the heartbeat request.

If the sender does not receive the heartbeat response sent by the receiver within the predetermined time after sending the heartbeat request, the receiver's heartbeat is considered to be stopped, that is, the receiver's working state is abnormal; if the sender is within the predetermined time after sending the heartbeat request Upon receiving the heartbeat response sent by the receiver, the receiver's heartbeat is considered normal, that is, the receiver's working state is normal.

Wherein, the sender is the load, the receiver is the remote control device; or the sender is the remote control device, and the receiver is the load.

Specifically, the first preset time after the remote control device sends the heartbeat request to the load, the heartbeat response from the load is not received, and the real-time heartbeat stop established with the load is determined;

Or, the first preset time after the remote control device sends the heartbeat request to the load, the heartbeat response from the load is not received; after the second preset time, the heartbeat request is resent to the load, and after the heartbeat request is resent Within a preset time, no heartbeat response from the load is received, and a real-time heartbeat stop established with the load is determined.

In this step, the request for the flight state information of the UAV when the working state of the load is abnormal includes the time when the working state of the load is abnormal, and the time when the working state of the load is abnormal may be the working state of the remote device determining the load. The time when the abnormality occurs may also be a preset time period before the time when the remote control device determines that the working state of the load is abnormal.

Further, after determining that the working state of the load is abnormal, the remote control device may further determine whether the specific abnormal condition of the load is detached from the unmanned aerial vehicle. For example, the sensor on the unmanned aerial vehicle can be used to know whether the load is changed relative to the position of the unmanned aerial vehicle, and whether the abnormal condition of the load is off the load from the unmanned aerial vehicle. If the position of the load changes relative to the unmanned aerial vehicle, and further, the degree of change is greater than the preset threshold, it is determined that the abnormal condition of the load is off from the unmanned aerial vehicle, and the remote control device can perform the following steps.

Step 102: The remote control device receives flight state information from the unmanned aerial vehicle, and estimates a geographic location of the load according to the flight state information.

In this step, the remote control device estimates the geographical position when the load is abnormal in the working state according to the flight state information; and/or, the remote control device estimates the geographical position where the load finally falls after the abnormality occurs in the working state according to the flight state information.

Wherein, the falling trajectory of the load may be generated according to the flight state information, and the address position of the load that finally falls after the abnormality of the working state is estimated according to the falling trajectory.

Wherein, when the working state of the load is abnormal, the geographical position information of the unmanned aerial vehicle is the starting point of the falling trajectory, and the geographical position where the load finally falls after the abnormality of the working state is the end point of the falling trajectory.

Optionally, after the remote control device determines that the working state of the load carried by the unmanned aerial vehicle is abnormal, the method is before the request to the unmanned aerial vehicle to obtain the flight state information of the unmanned aerial vehicle when the working state of the obtained load is abnormal.

In this step, the unmanned aerial vehicle may first establish a two-way communication mechanism with the load, and when the feedback signal of the load is not received for a predetermined time, it is determined that the working state of the load is abnormal.

When the working state of the load is abnormal (such as power failure, falling off the unmanned aerial vehicle, etc.), the communication link between the load and the UAV is interrupted, causing the communication between the load and the UAV to stop, so The communication mechanism determines whether the working state of the load is normal.

For example, a real-time heartbeat is established between the unmanned aerial vehicle and the load, that is, the sender periodically sends a heartbeat request to the receiver, and the receiver sends a heartbeat response to the sender within a predetermined time after receiving the heartbeat request.

Wherein, the sender is the load, the receiver is the unmanned aircraft; or the sender is the unmanned aircraft, and the receiver is the load.

Specifically, the first preset time after the unmanned aerial vehicle sends the heartbeat request to the load, the heartbeat response from the load is not received, and the real-time heartbeat stop established with the load is determined;

Alternatively, the first preset time after the unmanned aerial vehicle sends the heartbeat request to the load, the heartbeat response from the load is not received; after the second preset time, the heartbeat request is resent to the load, after the heartbeat request is resent During the first preset time, the heartbeat response from the load is not received, and the real-time heartbeat stop established with the load is determined.

Step 201: The remote control device receives a message that the working state of the load sent by the unmanned aerial vehicle is abnormal, and sends a request to the unmanned aerial vehicle to acquire the flight state information of the unmanned aerial vehicle when the working state of the load is abnormal.

Step 202: The unmanned aerial vehicle receives the request for the flight state information of the unmanned aerial vehicle when the working state of the acquired load from the remote control device is abnormal, and acquires the flight state information corresponding to the abnormal working state of the load, and obtains the flight state information that is obtained.
