Design of OPC-based data centre for solar energy water heating monitoring system

The OPC-based remote monitoring system was designed to solve the problems of wide geographical distribution and difficult monitoring existing in the solar energy water heating systems. The system overall scheme and composition are elaborated in detail. The basic principles of OPC technology and its data acquisition are introduced. The OPC technology is adopted to achieve design scheme of data centre in the remote monitoring system by means of Windows Form in the C#.NET platform,and realize the centralized management of each field monitoring terminal through a server in the data center,which possesses the functions of data acquisition,display,storage and failure warning. The practical application shows that the system works well,and has an excellent portability,so that it can be widely applied to the other industrial automation.
