Design Of The Aucomatic Meter Reading System Of Water, Electricity, GAS And Caloric

With the development of electron and computer, automatic meter reading system (AMRS) has a possibility to be put into reality. Especially for the well-to-do uptown, the Construct Department of China has demanded to realize integrate management of water meter, kilowatt-hour meter and gas meter step by step, gradually to realize automatic meter reading, measuring and charging with computer. This article aims at the existing problems, such as independent charging for the above meters, bad real-timing measured data, low efficiency, inaccuracy and so on. Thus, I designed an automatic meter reading system of water, electricity, gas, and calorie. The strong point of this system is: lows cost, precise measuring, stable working, and easy to install and maintain.The article gives an all-round design of this system. It expatiates on detail designs of data capturing and collecting, data communication network, and mode, main power supply, uninterrupted power supply for data capturer, switching circuit between the main power supply and the uninterrupted power supply. It introduces designs of anti-interference for this system, software of data capturer, data collector and PC. It also makes strict communication protocols for this system. According to the designs, I finished the hardware and the software, and I tested the work of system. Simultaneously, I analyzed the generality and the reliability of this system in brief.AMRS realized the remote meter reading of water, electricity, gas and calorie. It solved the problems of independent charging, manual data processing, and complicated charging. It will boost the automatic meter reading efficiently and has an enormous application prospect.
