This paper presents the design and implementation of an intelligent test system which is based on network AT89C52. The system monitors the working conditions of the system basic equipment through the use of RS 485 fieldbus technology. Focusing on the design and implementation of communication system,it describes structure of the system, functions of each part and realization of the program as well. The program has been successfully applied to the intelligent examination equipment in testing electronic equipment Troubleshooting skills. And this equipment has already become products. The result shows that the data transmission, which is expandable,low cost, good interoperability and with simple structure,is reliable and has a broad application.
