Design of intelligent node based on distributed hybrid net control system

TMS320F2182 DSP chip is applied in the design of intelligent node hardware, and the embed system design method, Microsoft Massage Bus and modularization technique are adopted in the realization of intelligent node. The paper gives the software design method of intelligent node based on CAN Bus. The data collected by intelligent node can be transmitted to computer in real time, and the distributed control system based on CAN Bus and GPRS presents the characters such as safety, real-time and economic, which is worth applying in process control field.
