Research And Appliction Of Electric Power Metering Automatization System Arehitecture Based On SOA

Design of system architecture is an important procedure of system development, the applied developmental direction of the system is determined by the architecture design.The C/S architecture is taken in most traditional architecture designing, as a result, a lot of problems appeared during the designing of automatic systems for electricity power measuring: function expanding becomes hard, information silo are formed and data can not be shared conveniently, unifying of archives structure is difficult and cross-product real time communication can not be realized, etc. Besides this, there are various internal systems in electricity power enterprises, data exchanges among these systems are frequent, therefore, data interfaces are complicated.The thesis takes the project is J2EE-based and Service-Oriented Architecture (SOA) is applied in multi-layer design and services designing. And the automatic measuring system for electricity power of Mao Ming as an instance, expatiates business of the system and designs some core functions in detail. The content of the design includes:1. The general system frame is designed to realize the multi-layer SOA, the system is divided into data layer, data management layer, application layer and interface application layer (WEB applications and C/S applications).2. Design of the archive structure is based on the CIM model and referred to the standard data structure of electricity industry, thereby data exchange with other systems is conveniently.3. The data communication with data collecting terminals consists of copying management parameters at any moment and noticing of alerts took place at data collecting terminals. The thesis borrows two message noticing mechanisms from JMS to implement the real-time communication, converts complicated binary communication protocol frames to readable XML formats through"Communication Proxy"module.4. The prepay function interface and the marketing system interface are designed as instances of data exchange, interface service names and XML document formats are enumerated.The Service-Oriented architecture is introduced in the paper which is based on practice. Electricity application systems should make a quick response to changful market demands.
