Problems solved by technology
[0004] Since direct contact with pesticides will inevitably cause harm to the human body, and the emergence of drones has avoided this phenomenon. Therefore, the benefits of using drones for pesticide spraying are self-evident. The real-time monitoring effect of man-machine spraying pesticide flow is very poor. For example, the application number is N201610242942.X "UAV spraying flow detection method and device", which introduces the method of using non-contact speed sensor to obtain the flow rate, which often has the following disadvantages :
[0005] First, it is impossible to judge the relationship between the flight state of the UAV and the current flow; second, it is impossible to determine the current flow value of the UAV spraying according to the actual situation inside the spray pipe and at the nozzle of the spray pipe; The environmental factors faced by the UAV determine whether the spray nozzle is faulty

Embodiment
[0042] see figure 1 and figure 2 , the present invention provides a technical solution: a method for monitoring the spraying flow of pesticides by drones, comprising:
[0043] Store the flight status of the previous stage of the drone, receive the flight status of the drone at the current stage, and determine whether the current flight status of the drone is adjusted by comparing the flight status of the previous stage of the drone with the flight status of the current stage;
[0044] Store the flow state before the liquid outlet of the drone in the previous stage, receive the flow state before the liquid outlet of the drone at the current stage, and determine the current flow state before the liquid outlet by comparing the flow state of the drone before the liquid outlet in the previous stage and the flow state before the liquid outlet in the current stage. Whether the flow is adjusted;
[0045] Store the flow status of the liquid outlet at the previous stage of the drone,...

The invention discloses a method for monitoring the flow rate of pesticide spraying by UAV, which includes storing the flight state of the UAV in the previous stage, receiving the flight state of the UAV in the current stage, and comparing the flight state of the UAV in the previous stage with the flight state of the current stage Determine whether the current drone flight status is adjusted; store the flow status before the liquid outlet of the drone in the previous stage, and receive the flow status before the liquid outlet of the drone in the current stage; pass the flow status of the liquid outlet in the previous stage of the drone and the current stage Comparing the flow state when the liquid exits to determine whether the flow rate is adjusted at the current exit; whether the current UAV flight state is adjusted, whether the flow rate before the current exit is adjusted, and whether the flow rate is adjusted at the current exit to determine the flow value of the current UAV pesticide spraying; it can be judged The relationship between the flight state of the UAV and the current flow; the current flow value sprayed by the UAV can be determined according to the actual situation inside the spray pipe and at the nozzle of the spray pipe.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicle pesticide spraying, in particular to a method for monitoring the flow of unmanned aerial vehicle pesticide spraying. Background technique [0002] UAVs can be divided into military and civilian according to the application field. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civil use, drones + industrial applications are the real needs of drones; currently, they are used in aerial photography, agriculture, plant protection, miniature selfies, express transportation, disaster rescue, observation of wildlife, monitoring of infectious diseases, surveying and mapping, news reports, and electric power patrols. The application in the fields of inspection, disaster relief, film and television shooting, manufacturing romance, etc. has greatly expanded the use of the drone itself, and developed countries are also actively expandin...
