Laser forklift traffic control system

Abstract

The invention discloses a laser forklift traffic control system which comprises at least one laser forklift and a traffic control device in communication connection with the laser forklift. The reflector is arranged on the periphery of the walking path, a plurality of main stations are arranged on the walking path, sub-stations used for taking and placing goods are arranged near the main stations,and the laser forklift moves back and forth along the walking path; the traffic control device controls starting and stopping of the laser forklift based on the locking list, the laser forklift ID far away from the first conflict road section or the first conflict station is added into the locking list of the conflicted laser forklift, meanwhile, the conflicted laser forklift is controlled to stop, and after conflicts are removed, and the conflict laser forklift ID is deleted from the locking list of the conflicted laser forklift, and the conflicted laser forklift is started. After the task attributes of the laser forklifts are compared pairwise, starting and stopping of the laser forklifts are controlled according to the locking list, the method can effectively solve the traffic controlproblem of coexistence of the multiple laser forklifts, and the method is suitable for the laser forklifts with two-way paths.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and more specifically, the invention relates to a laser forklift traffic control system. Background technique [0002] With the development of factory production automation and information integration, modern industrial production puts forward higher requirements for material systems. Automatic guided forklift (AGV) is an automated transportation device that can complete specified transportation tasks in a given path and scene. Laser forklifts based on reflector navigation have been widely adopted by the industry due to their high flexibility, simple laying, small driving radius, and easy route changes. With the improvement of production automation and the expansion of production scale, a single laser forklift can no longer meet the actual needs, and more and more factories require multiple laser forklifts to coordinate and cooperate to complete tasks. [0003] Due to the limitation o...

Problems solved by technology

[0004] The application number "201811605972.8" is titled "A Traffic Control Method for Automatic Traction of Forklifts", which divides the operating area of ​​forklifts into traffic control operating areas and non-traffic control operating areas. It is suitable for multi-intersections and cannot be used for two-way road sections. If the map is changed, it is necessary to recalculate and change the traffic control area and non-traffic control area in the dispatching system, which is more complicated
