Abstract

The application relates to an AGV scheduling technique for a flexible manufacturing system. According to the AGV scheduling method in a manufacturing system, the manufacturing system is composed of amanufacturing execution system (MES), a plurality of independent units separated from each other, a plurality of AGVs for material distribution, an AGV scheduling unit for the plurality of AGVs, and an AGV-PLC in communication with the plurality of AGVs and the AGV scheduling unit. The method comprises: the AGV-PLC communicates with the AGV scheduling unit to inquire a current available AGV; whenany AGV is available, the AGV-PLC accesses an AGV scheduling task table maintained by the MES in a database server to obtain a to-be-executed AGV scheduling task; the AGV-PLC parses the obtained AGV scheduling task and generates a corresponding AGV transportation task; and the AGV-PLC transmits the AGV transport task to the AGV scheduling unit.

Description

technical field [0001] The present application relates to an AGV scheduling technology, in particular to an AGV scheduling technology in a flexible manufacturing system. Background technique [0002] The development and application of the intelligent manufacturing industry has increasingly put forward requirements for flexible production. One aspect of flexible production is the establishment and use of flexible manufacturing systems (FMS). [0003] Generally, flexible manufacturing system refers to an automated manufacturing system that is composed of several numerical control equipment, material handling and storage devices, and computer control systems, and can be quickly adjusted according to changes in manufacturing tasks and production varieties. Flexible manufacturing systems generally realize the flexibility of the system from the aspects of machine functions, processes, products, maintenance, and scalability. For example, a typical flexible intelligent manufacturi...
