Semi-automatic control system used in operation of plant protection unmanned aerial vehicle

Abstract

The invention provides a semi-automatic control system used in operation of a plant protection unmanned aerial vehicle. Under the semi-automatic mode, a conversion unit can convert a left-right direction control signal set by a setting unit into an automatic control signal; after a flight control part receives the automatic control signal, a collection unit collects the real-time lateral flight speed of the plant protection unmanned aerial vehicle, a calculation unit calculates the real-time flight speed and time to obtain the lateral flight distance, a comparison unit compares a lateral movement distance stored in a storage unit with the lateral flight distance to obtain a comparison result, and a control unit controls the plant protection unmanned aerial vehicle to continue lateral flight or not according to the comparison result. Thus, after receiving the left-right direction automatic control signal, the plant protection unmanned aerial vehicle can automatically move laterally by a preset distance. Therefore, by means of the semi-automatic control system used in operation of the plant protection unmanned aerial vehicle, the problem of non-uniform spraying under manual operation can be avoided, and the operation difficulty can be lowered for of flight control staff.

Description

technical field [0001] The invention belongs to the control technical field of a semi-automatic control system when a plant protection machine is in operation, and in particular relates to a semi-automatic control system for a plant protection machine in operation. Background technique [0002] At present, the operation of plant protection drones is mainly divided into two types: manual operation and automatic spraying. However, due to the complexity of farmland boundaries, many obstacles, and inaccurate sensor measurement offsets, automatic spraying still has great limitations and cannot really be popularized. So now the operation of the plant protection machine mainly depends on the manual operation of the flight controller. In the process of manually controlling the plant protection machine to spray back and forth, it is very difficult for the flight controller to ensure that the ridge distance of the plant protection machine is the same and accurate each time, especiall...
