Abstract: A new distributive control and management system for refrigerator assembly lines is described. The problems met in ClMS. including tctal-c'istiituthr rcntrcl, the communiction network between difference devices, the arrangement constraint in space and function, fault diagnosing, the fault-tolerant technique and selforganizing of the system, are solved. The step fry step sequential control method based on Petri Net Theory is introduced. Experiments show that the system provides an efficient approach to workshop automation.
