A kind of long-range and centralized automatic metering reading for water meter system is designed. The function of the GPRS network meter reading and the USB centralized meter reading are accomplished by the M23 GPRS module and the C8051F340 single chip micro-controller. The system is composed of water meter, data collector, concentrator and administer computer. The data of water consumption which will be converted into pulse signals are collected by the water meter, and these pulse signals are disposed by the data collector which can use RS-485 communication with concentrator, water user's machine can be controlled when the upper instructions are received by the way of controlling the electromotion valves. The Concentrator plays an important role in data transit and bus segregation. A USB interface is set up in the concentrator in order to avoid the failure of GPRS network, and the staff can copy the datas by computer or hand-written. The administer computer can manage the user's purchase of water and control the user's machine by sending specific instructions.
