Operation road surface detection system and method for automatic guided vehicle

Abstract

The invention is suitable for the field of laser range finding, and provides an operation road surface detection system and method for an automatic guided vehicle. The system comprises a laser range finding sensor, a motor coder connected with the motor of the automatic guided vehicle, a motor driver and a main controller which are respectively connected with the motor of the automatic guided vehicle and the motor coder, and a communication module which is connected among the laser range finding sensor, the motor driver and the main controller. The laser range finding sensor is a laser range finding sensor of a diffuse reflection type, is fixed at the upper part of the body of the automatic guided vehicle, and transmits detection laser to an operation road surface of the automatic guided vehicle at a fixed frequency and a fixed inclined angle, wherein the detection laser comprises a plurality of laser beams which are located in the same plane and the adjacent laser beams form the same inclined angle. According to the invention, the laser range finding sensor of a diffuse reflection type is used for transmitting the plurality of laser beams which are located in the same plane to the road surface at the fixed frequency and fixed inclined angle, and can achieve the detection of the trench size and obstacle size of the operation road surface of the automatic guided vehicle, wherein the adjacent laser beams form the same inclined angle.

Description

technical field [0001] The invention belongs to the field of laser ranging, and in particular relates to a running road surface detection system and method of an automatic guided vehicle. Background technique [0002] Automatic guided vehicles and cruise equipment are widely used in unmanned factories, automatic assembly and transfer workshops, power substations and other fields. However, these automatic guided vehicles and cruise equipment can only automatically run in the planned path and environment, and can only detect obstacles protruding from the ground such as people or objects, and cannot accurately detect ground trenches, resulting in The scope of application is very limited. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide an automatic guided vehicle running road surface detection system and method, aiming at solving the problem that the automatic guided vehicle and cruise equipment in the prior art can only...
