[Abstract]:In recent years, the problem of energy shortage in the world is becoming more and more prominent. People begin to pay more attention to the effective use and management of energy. Because sensor network technology is easy to set up network in the process of implementation, it has the advantages of low cost and low power consumption. Widely used in medical, energy and industrial fields. Taking the energy management of regional buildings as the starting point and ZigBee wireless sensor network as the technical support, this paper develops an energy management system for regional buildings, which effectively overcomes the difficulty of networking and wiring of traditional systems. The disadvantages of poor expansibility and high cost. The system consists of three parts: terminal acquisition node, coordinator and management center. The wireless sensor network is composed of terminal acquisition node and coordinator, which provides a reliable and convenient channel for data transmission. The management center realizes the real-time management and control of energy consumption information through monitoring software, and further realizes the positioning of energy consumption information in combination with geographic information system, which makes energy management have higher spatial dynamics. This paper first discusses the development status and research significance of this topic, carries on the advantage to the traditional energy management system, utilizes the ZigBee and the geographical information system unifies the huge superiority, carries on the function demand analysis to the regional building energy management system. The overall implementation plan has been formulated. Secondly, the hardware and software of the acquisition and transmission node are designed. For hardware design, the peripheral circuit schematic of node module based on CC2430 RF chip and the design of PCB are completed. For the software design, on the basis of deeply studying the ZigBee protocol stack architecture, the network building process of the coordinator and the equipment entering the network, combining the characteristics of the system, the reconnection mechanism of the isolated point is put forward, and the terminal node is realized by programming. Data transfer between the coordinator and the router. Then, the database and monitoring software of the management center are designed and developed. In the environment of VC 6.0, the GIS is integrated into the management center software, then the software can get the energy usage of the terminal node through statistical analysis of energy consumption information. Furthermore, the decision and scheduling strategy of the total energy consumption information of regional buildings is provided. For multi-region energy management, through analyzing and studying the condition factors that affect the performance of database connection, the method of database performance optimization is put forward. Finally, the stability of node communication is tested, and the star network system is further tested. The system has high feasibility and stability, and can effectively manage energy consumption information. According to the data analysis, a reasonable and reliable energy distribution scheduling scheme is given. Effectively promote the development of regional building energy management system.
