Design And Research Of Wireless Power Remote Meter Reading Monitor Terminal

With the development of the living standard of the people and increases of the number of enterprise and residents, the traditional way of meter reading's drawbacks has appeared, it not only appeared people's normal life, but also made great economic losses of power department. Nowadays the electronic and communication technologies develop rapidly, the more electronic, more automatic and more intelligent meters have replaced manual meter. Wireless power remote meter becomes the trend of meter's development.Therefore, this paper designs a kind of wireless power remote meter monitoring terminal which takes GSM as the wireless communication mode. This paper introduces the development present situation of the wireless remote electric meter reading system, and elaborates the composition and the operational principle of the meter reading system, the composition and features of GSM communication system, short message services and the function of monitoring terminal and so on. It also shows the detailed analysis and design of the terminal's hardware system and software system.In my studies, using the ATmega32 microprocessor as the micro controller, and using ATT7022B as the power chip and TC35 as the wireless communication module for the hardware design of the wireless remote electric meter-reading monitoring terminal. Gives the detailed instructions and introduce of each module's principle, performance and relevant issues in hardware design process and show the specific circuit design. Then designs the software system on the base of hardware design for the function requirement, shows the software flow, and deals with the design idea of software.Through the functional test of the terminal shows that terminal can realize data acquisition and measure, data and time local display, information transmission to data center regularly, power data storage, parameter modification by key and so on, achieves the desired goal. The terminal has the advantage of high integration, the long transmission distance, low cost, reliable data transmission, easy installation, no wiring etc, it has high performance-price ratio and good application prospect..
