Design of the Intelligent Water Meter

Abstract Design of the system in response to changes in the water system of the state, to realize the informatization and automation of water control and management of the made research and development, to ease the pressure on the water plant because of funding problems caused by, reduce the workload of the staff of each month and solve the problem of arrears caused by water users, using advanced scientific methods to enable the outdated water management system change。 The IC card intelligent water meter with single chip microcomputer as the core can not only improve the running efficiency of the water company, but also can effectively improve the user's water saving and the awareness of the effective water use。 Because of the above reasons, the IC card intelligent water meter, which is the core of the single chip microcomputer, is more and more popular with the water plant and the users。

The to MCU as the main control IC card intelligent water meter circuit for the design and development, its core is the AT89S51 microcontroller as the control center, to complete the card read and write function, effectively in charge of LCD and valves, timely access to the metering pulses。 And also has a safety protection circuit, storage module, signal transmission circuit, can effectively deal with the data of the entire system, with the completion of the entire water meter monitoring ability。 In this paper, the design of hardware circuit is discussed in detail, and the design process of hardware and software is discussed in detail。
