Design of Net-Based Intelligent Control and Protection System for Electromotor

An intelligent control and protection system for electromotor is introduced, which is based on LonWorks field bus. The system structure, functions, features, hardware design and software flows are discussed. The system consists of the monitoring and control center, the communication module, the analysis and processing module and the signal processing and output control module. It has the functions of electromotor control and protection, measuring and communication, and it realizes the automatic, integrated, intelligent and net ?like management of electromotor. The system has put into operation, and the practice shows that its performance is excellent.
