Design And Implementation Of Message Oriented Middleware In Scada System

With the development of distributed technology, the distributed system with its advantages in stability, scalability, reliability, has been applied in many fields. Because of the "information island" phenomenon is widespread in the distributed system, so, how to integrate these subsystems together and realize information interconnection, resources sharing, has become an urgent problem to be solved. Message oriented middleware can provide a transparent and efficient message transmission mechanism for the application in a distributed environment, it can effectively solve the problem of information interaction between subsystems, and has got extensive attention in the process of project development. Electric power dispatching automation system is an important field of distributed applications, therefore, according to the characteristics of SCADA system, and then carry out the special and effective technology research of message middleware system is of great significance.In this paper, firstly the concept, classification, technical principle, the communication model of message middleware are studied, after the mainstream message oriented middleware design ideas and relevant technology are called. According to the requirements of application, the system architecture design is proposed, and the function modules are divided. Finally, a message oriented middleware based on message queue in SCADA system has been made out.This message oriented middleware not only provides a highly efficient and stable data transmission services, but also effectively improves the efficiency of the power grid operation and brings considerable economic benefits for the enterprise, since it is put into operation. Practice has proved that the message oriented middleware applied in SCADA system has reached the design requirements, and has broad application prospects in the field of electric power dispatching automation.
