Design and Application of CANBUS Distribution Computer Control System

The constitution principle of the hardware and the design method of the software of the distribution control system based on CANBUS are introduced. The whole system is composed of industrial control computer/server, network communication controler, field controller and remote computer. The system software adopts internet/intranet and web technique and establishes computer data processing system with browser/server as the model. The application of the control system to boiler steam thermonet monitoring system has shown that the system has such characteristics as strong anti-jamming, easy field configuration, high degree network connections and friendly man-machine interface, etc.
