Due to the large number and distribution range of mirror field equipment in tower solar thermal power plants,there are often thousands of heliostats.Single sided heliostats usually have hundreds of non-real-time data and dozens of real-time data that need to be effectively managed and monitored,which is difficult for conventional decentralized control systems to meet monitoring requirements.This paper proposes to build a communication and data management server based on advanced communication technology,database technology,and Web technology.The operator station can use a browser to monitor and operate devices globally,in groups,and individually,monitor network status in real-time,and effec-tively manage device parameters.
