ABSTRACT
The traditional manual meter reading way has been increasingly unable to meet the needs of modern management. Along with the electronic technology and munication development, the water management automation and information will be gradually implemented .The non-contact IC card intelligence water meter is a new type of automated water meter system. It has a very good prospect of application. This thesis focuses on the study of intelligent water meter system. Firstly, the non-contact IC card intelligence water meter system is studied. Then we take the high performance embedded microprocessor as the core,and use the technology of Radio Frequency Identification (RFID), to achieve the designs of non-contact IC card intelligence water meter system. The main research results are as follows:
(1)According to the design demand of intelligent water meter to study the general scheme of intelligent water meter,the intelligent water meter's hardware systems, software systems and several key technical issues are discussed and studied.
(2) According to the intelligence water meter performance, we firstly study the general structure of intelligence water meter. Then based on the embedded microprocessor 8051 .we design the hardware systems of the non-contact IC card intelligence water meter, and realize the design of the hardware system frame, the flow of water collecting units, the flow of water processing unit, the IC card and the reading unit.
(3) The software system of the non-contact IC card intelligence water meter are
