Problems solved by technology

[0003] The green lawn is a "biological carpet" composed of countless vibrant grasses. The purpose of precision mowing is to achieve the finishing and beautification of the lawn without damaging the turf and root tissue of the lawn. Therefore, digging and laying electromagnetic wires or Sticking guide signs on the lawn is not suitable for the positioning and guidance of precision automatic lawn mowers

Embodiment Construction

[0058] Such as image 3 , the system provided by the present invention is divided into three parts and seven modules. The first part is installed on the car body of the lawn mower, including four modules of central monitoring, motion control, laser positioning and navigation and ultrasonic control. The master-slave interface is formed between each module through the RS485 bus, wherein the central monitoring module is master, and the rest are slaves. The second part includes a handheld remote control module, which communicates with the central monitoring module through an infrared interface. The third part includes two distributed remote beacon control modules, wherein: one remote beacon control module is installed in the remote beacon device 1 , and the other remote beacon control module is installed in the remote beacon device 2 . The functional structures of the two modules are exactly the same. Each remote beacon control module establishes a data communication link with ...

Abstract

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).

Description

technical field [0001] The invention relates to the positioning and track motion control technology of an automatic guided trolley, in particular to the distributed beacon laser scanning positioning and navigation of an automatic precision lawn mower, the position finding of the vehicle body corner displacement posture, position coordinates and angular displacement compensation intelligent trajectory control, ultrasonic Distance measurement and anti-collision control technology. It is suitable for precision mowing of high-end lawns and occasions with high requirements for lawn beautification. Background technique [0002] The navigation and positioning system of traditional automatic guided vehicles mostly adopts the positioning and guidance method of laying electromagnetic wires or ribbons as navigation marks. This guidance method is fixed and the programming is simple. The automatic guided vehicle can only follow the preset wire or ribbon Track motion, lacking the flexibi...
