Description

Technical Field

[0001] The invention relates to an automatic shortest path dispatching system for an automatic trolley, belonging to the technical field of industrial automation. Background Art

[0002] Automated Guided Vehicle (AGV) is a type of mobile robot. AGV is also known as unmanned transport vehicle, automatic navigation vehicle, and laser navigation vehicle. Its notable feature is that it is unmanned. The AGV is equipped with an automatic guidance system, which can ensure that the system can automatically travel along the predetermined route without the need for manual navigation, and automatically transport goods or materials from the starting point to the destination. Another feature of AGV is its good flexibility, high degree of automation and high level of intelligence. The driving path of AGV can be flexibly changed according to changes in storage space requirements, production process flow, etc., and the cost of changing the running path is very low compared to traditional conveyor belts and rigid transmission lines.

[0003] AGV is generally equipped with a loading and unloading mechanism, which can automatically interface with other logistics equipment to automate the entire process of loading and unloading and handling of goods and materials. In addition, AGV also has the characteristics of clean production. AGV relies on its own battery to provide power, and there is no noise or pollution during operation. It can be used in many places that require a clean working environment.
