Precise automatic lawnmower distributed beacon laser positioning and trajectory control system

The present invention provides a precise automatic lawnmower distributed beacon laser positioning and trajectory control system. In the aspect of hardware, a distributed communication structure formed by an RS485 bus and a radio frequency module is employed, each module internal algorithm runs independently, the data traffic of the system is reduced greatly, the communication block is eliminated, and the system processing speed is improved. In the aspect of software, the functions of laser automatic scanning, distributed beacon distance measurement, motion trend judgment, ultrasonic distance measurement, wireless communication, trajectory control, automatic collision prevention are combined together, the precise automatic mowing function of the intelligent precise automatic lawnmower is realized, and the requirements of beautifying a lawn and the purpose of saving energy and protecting environment are achieved through intelligent precise and automatic lawn mowing. The system is also applicable to the automatic navigation and track control of an automated guided vehicle (AGV).
