Working Principle Of Laser Guided AGV Trolley

The laser guided AGV car is the most important AMR technology in the development of AGV so far. It mainly includes two parts: the AGV laser scanner and the AGV reflector. The laser scanner installed on the AGV car rotates 360 degrees at a fixed speed. The pulse laser emits laser light to the reflector, and the direction of the laser reflected by the reflector, the laser scanner can detect the reflector and get the laser light. Angle and other information, the AGV on-board computer receives and processes the information, calculates the position of the AGV and the direction of movement, and corrects the position by comparing it with the parameters built in the upper control system, thereby guiding the AGV to follow the pre-set route. In addition, in the laser guidance system, a certain number of reflectors are strategically installed in the designated area. This is for all reflector data (including the XY coordinates of the reflector) and the reflector in an AGV work area. The facing direction (that is, the angle of reflection) can be accurately marked in the citation system.

1. The application of laser guided AGV trolley

AGV trolleys can easily and flexibly enter and exit all kinds of production, assembly lines, conveyor lines, machines, stations, shelves, etc., which can basically meet the needs of warehousing and logistics. Automatic production lines such as packaging have high flexibility, large material flow, and fast response time. . However, it needs to plan the operation route of the AGV in advance, and the position of each laser reflector in the production workshop cannot be moved at will, and the fixed position of the reflector is also required to be accurate. Only in this way can the AGV be prepared to calculate the travel path. In addition, the technology also introduces the two main functions of laser guidance technology, position calculation and collision protection, to improve the driving stability of the AGV.

2. The development prospects of laser-guided AGV trolleys

Laser guidance technology is a key topic and development trend in the field of AGV research. Many researchers in the world are committed to improving the accuracy, real-time and reliability of AGV path recognition and position calculation. The introduction of position calculation and anti-collision protection functions improves the driving stability and transportation efficiency of AGVs, improves the flexibility and safety issues in the warehousing logistics system, improves the level of automation and management of enterprises, and also contributes to the development of AGVs. Open up broader application prospects.
