A three-layer structure module based on system level,module level and application level is presened,a multithreaded computing module based on four-layer C/S structure and a real-time communication protocol are discussed,This module has a fine application prospect.

Improvement of real-time protocols based on industrial ethernet;

Ethernet Real-time Protocol for Measurement and Control Systems;

In order to realize message data communication we must develop special software with real-time protocol under real-time operating system.

Design of communication protocol at link layer of a mine monitoring system;

The study of the communication protocol and the mobile and base station of mine mobile communication system;

the Study and Design of the Remote ECG Monitoring System Communication ProtocolD;

Dual CAN Bus and Its Communication Protocols of Monitoring and Control System Based on DSP56F807;

Study of the communication protocols of the intelligent network disk;

How TO Configure the Communication Protocols of the LAN;

The remote control automatic diesel generating sets communication agreement;

Applications of CAN bus in Li-ion battery testing system and the configuration of the hardware and the flow chart of software are introduced,the establishment of the communication agreement being explained.

This paper presents the technology of fault handling for the long range supervisory and control equipment, the design of software and hardware for terminal, the choice of the communication agreement and the structure of communication net, the choice of the arithmetic for fault judging .
