Automatic Meter Reading System Research Based On Radio Frequency Network

With the rapid growth of population and technology, the electric power consumption and number of consumers have increased quickly. In order to serve larger consumers more effectively, it is urgent to develop a new kind of meter reading system which can supply many necessary services, for instance, efficient meter-reading,reliable power monitoring and control. Supplying the capabilities above is a development tendency for utility company to promote service quality and the management efficiency in the future. With rapid growth of mobile communication and radio frequency (RF) technology, wireless communication technology which has advantages such as low cost,high expansibility and maintainability,less limit of physiographic condition,easy installation makes it possible to use radio frequency (RF) technology to design the Wireless ARM-Based Automatic Meter . Reading System(WAMRS) which can achieve on-line, high speed data transmission service and satisfy the need of data transmission speed for reading digital meter.This test argument a lot about feasibility and advantage of the wireless automatic meter reading system based on radio frequency (RF) technology. First the test instructs some kinds of radio frequency chip with their principle and characteristics, then upon data collection terminal request the test uses microprocessor chip and radio frequency chip to construct communication module, and because of the short communication distance of the radio frequency (RF) chip the test adopts automatic routing technology in the wireless automatic meter reading system to communicate with each node. At last, the test simply introduces the hardware and software of the communication module, and explains the automatic routing arithmetic of the wireless automatic meter reading system, then gives an automatic routing arithmetic which satisfies the demand of the real system. The practice shows that the automatic meter reading system using short radio frequency (RF) technology is stably and reliably, satisfying the design request. It improves the safety and economical operating level of the distribution network and enhances the energy management and power supply quality.
