Based Gprs Electric Energy Management System Architecture And Application

Electrical equipment through real-time monitoring of management will enable enterprises to better power supply to provide quality services to customers. For special transformer, state Area, and other large users of electricity scattered occasions, it is necessary to realize the scene management of electricity, electric energy remote communication technology is very important. Wireless public networks for decentralized measurement points provides a remote management technology, GPRS wireless network technology has entered the mature stage of the GPRS based on the electric energy management system architecture to better meet the demand of power supply enterprise information has become electric energy management system development.Software architecture design is an important process of software development, architecture design system determines the direction. Traditional architecture designed for use mainly to C / S-based architecture, this software system architecture to bring a lot of questions, such as the expansion function is very difficult; easy to produce "information isolated island", data sharing is not convenient; file structure cannot be unified; cannot be achieved cross-product of real-time communications. Now many internal systems of electric power enterprises, the data exchange between systems is very large, leading to the complexity of data interfaces between systems.In this design, using WebLogic J2EE standard build to SOA architecture layered on the entire system design and service design, and then the power company in Shandong Heze GPRS based on the application of electric energy management system as an example, the system of operations, and the main business processes and functions carried out a detailed design. Mainly include:1) system architecture design, using SOA architecture for hierarchical design, the system including the data access layer, business layer, business layer interface, the user interface layer (WEB applications and C / S applications);2) system file structure design, with reference to the power industry standard data structure designed to facilitate comparison with other systems of power supply enterprise data interaction;3) The system uses a "green APN of GPRS-based network program," the realization of the measurement points and on-site data communications, and realize the on-site data terminal management as well as the parameters of the data terminal for real-time generated alarm notification message using JMS notification mechanism to achieve real-time communications and the complexity of the Statute of the binary communication frame into the XML format for easy readability.4) In this design, and power marketing system as an example of data interfaces for interactive design, examples of the Service interface methods, as well as the definition of XML document format.In this design will be based on practice, the service-oriented architecture to model the introduction of software project development. GPRS-based electric energy management system architecture can quickly respond to changes in demand for the electricity market.
