The Electric Quantity Data Acquisition System Based on Wireless Sensor Network

This paper introduces an electric quantity data acquisition system based on WSN, and a special algorithm which is used in multi-channel electric data acquisition is also introduced. In this algorithm, a large number of hardware circuits are replaced by software functions, the design of the hardware is simplified, and it is of practical value. The system includes pulse kilowatt-hour meters, Data Acquisition(DAQ), data concentrators, Server and Zigbee network nodes (Router and Coordinator) and so on. This paper explains the structure of Zigbee network, the network features of DRF1605H Zigbee module, the special algorithm of electric quantity data acquisition, the structure of WSN electric quantity data acquisition system, the design of electric quantity data acquisition hardware and software and so on. After designing and implementing this system, the electric quantity data acquisition, the data transmission between each ZigBee node and the ability of anti-interference are tested. The results of each test show that each part of the system works properly and meets the original requirements of the design. From the running condition of the system, the system for electric quantity data acquisition and transmission has some characteristics such as a simple structure, accurate data, a strong anti-interference ability, high reliability of WSN, easy maintenance, good scalability and so on, which indicate it has a promising application future. This system helps to plan the use of electricity and dispatch the power. Not only is the electric energy management automation level improved, but also manpower and material resources are saved, leading to remarkable economical benefits.
