Electric Energy Management System Based On Sensor Network

In recent years,the world's energy shortage problem has become increasingly prominent,people began to gradually focus on the effective use and management of energy,sensor network technology in the implementation process to facilitate networking,low cost,and use the advantages of low power consumption,widely used in medical,Energy and industrial fields.In this paper,the energy management problem of regional architecture is taken as the research point,and ZigBee wireless sensor network is used as the technical support to develop the regional building energy management system,which effectively overcomes the shortcomings of traditional system cabling,poor expansion and high cost.This system includes the terminal collection node,the coordinator and the management center.The wireless sensor network is composed of the terminal collection node and the coordinator.It provides a reliable and convenient channel for the data transmission.The management center realizes the real-time information of the energy consumption through the monitoring software Management and control,and further integration of geographic information systems to achieve the positioning of energy consumption information,so that energy management has a high spatial dynamics.This paper first discusses the development of the subject and the significance of the study,the traditional energy management system to avoid weaknesses,the use of ZigBee and geographic information systems combined with the great advantages of regional building energy management system functional requirements analysis,the overall implementation of the program.Secondly,the hardware and software design of the acquisition and transmission nodes are carried out.For the hardware design,the CC2430 RF chip based on the node module peripheral circuit schematic and PCB design.For the software design,in addition to the Zig Bee protocol stack architecture and coordinator network construction,equipment network based on the process,combined with the characteristics of the system network,proposed a solitary point reconnection mechanism,and programming to achieve the terminal nodes,coordinator and Data transfer betweenrouters.Then,the design and development of the management center of the database and monitoring software.In the VC ++ 6.0 environment,the geographic information system is integrated into the management center software,the software can analyze the energy consumption information to obtain the energy usage of the terminal node,and then provide the decision and scheduling strategy of the total energy consumption of the regional building energy.For multi-regional energy management,through the analysis of the impact of database connectivity performance factors,the database performance optimization proposed a method.Finally,the stability of node communication is tested,and the joint test of star network system is carried out.Through the results of the jointing can be obtained,the system has a high feasibility and stability,can effectively manage energy consumption information,and according to the data analysis gives a reasonable and reliable energy distribution scheduling program,effectively promoted the development of regional building energy management system.
