Water companies in China are mostly rely on the traditional model of artificial check water meter and charge fee, the traditional way has many shortcomings, such as time-consuming, need artificial. According to the current situation of the development of intelligent water meter at home and abroad, on the basis of design for a IC card intelligent water meter control system based on single chip microcomputer. This system with the single chip processor as the core component, through wiggins sensors to detect the user "s water consumption, the use of the IC card read and write and encryption technology, to realize to buy water and water management. This paper completed the system hardware circuit design and software design.Hardware circuit USES modular design, including the water detection circuit, IC card interface circuit, electromagnetic valve driver circuit, alarm circuit, LED display circuit, etc., are analyzed in detail the working principle of each module and the work performance; The system software USES the assembly language preparation, and gives the specific program written.The system identification, water meter with IC card automatic water supply, power protection, LED display, intelligent control, anti interference and anti electromagnetic valve disassembly, and other functions
