Autonomous battery replacing device of rotary propulsion type plant protection unmanned aerial vehicle

The invention relates to an autonomous battery replacement device of a rotary propulsion type plant protection unmanned aerial vehicle. The device is composed of the following four modules: a cabin door autonomous opening and closing module, an unmanned aerial vehicle precise landing module, a rotary push type battery autonomous replacement module and a solar power supply module. The four modules are all controlled by a single-chip microcomputer to operate. The device is in the shape of a cube, and all components are distributed in the device. The cabin door automatic opening and closing module uses a microwave laser radar technology, a sensor is installed on a cabin door, and when the unmanned aerial vehicle gets close to the device by a specified distance, the cabin door is automatically opened; aiming at the problems of low precision, errors and the like of a traditional navigation mode, an unmanned aerial vehicle precise landing module uses devices of an RTK (Real Time Kinematic), a GPS (Global Positionin
