| Along with the development of our economy and the gradual progress of urbanization, managing electrical energy real-time efficiently is an urgent matter. To improve the level of automated management in the field of electrical energy, the electrical energy department need reform and upgrade the old system. In addition, with the urban transformation of the old residential areas and the new construction of new buildings and low-income housings, they have provided application environment and broad space for the research of electrical energy management system.Firstly, according to the development status and problems of electrical energy management system, this article analyzes the overall structure and basic elements of electrical energy management system. At the same time, this article compares and analyzes characteristics and application areas of various communication technologies.Secondly, in the paper, a design scheme of electrical energy management system based on ZigBee and GPRS is proposed. On the one hand, according to measurement module, collector, concentrator in the system, the paper finishes the hardware circuit design, which consists of voltage and current conversion circuit, measurement module circuit, data protection circuit, power circuit, and so on. At the same time, the paper finishes the corresponding software design. On the other hand, in the paper, ZigBee protocol stack is migrated on the development board, data transfer protocol is designed and management software in the management center, and so on.Finally, the paper finishes the system test from the aspects of accuracy of measurement module, ZigBee network, data transmission reliability and other aspects. Moreover, the paper analyzes the result.Electronic energy management system from practical application focuses on application technology of microprocessor, control technology of computer, communication technology and other technologies. The system contains many functions, including collecting data from meter in the distance way, querying the data instantly, measuring all kinds of electrical data of transformer substation, analyzing the data as well as billing based on time, and so on. The system has a lot of features, such as simple construction, low cost, fast and easy maintenance and so on. Moreover, the system improves the management level of electrical energy and realizes the goal of managing electrical energy timely, accurately and efficiently. |
