分布式桥梁健康监测系统研究

his paper designs a distributed measurement and control system based on the combination of PC and lower monitor PLC,Apply the system to bridge health monitoring is a feature in this paper.With its low failure rate, powerful, compact structure and good adaptability,Programmable controller (PLC) is widely used in industrial control applications.In this system,as understratum control unit,PLC can execute distributed control efficiently,and decentralized control PC can provide friendly human-machine conversation interface and powerful data processing functions.Achieving their complementary strengths,and composing cost-effective monitoring system,is the key point of this paper.
