According to the requirements of water quality, water supply pressure and water supply system reliability,a new auto- matic control system of water supply with constant pressure and frequency conversion which combined with advanced automa- tion and communication technology was designed. This system based on inverter frequency modulation technology and a typical Micro Control Unit（MCU） AT89C51 as a controller and a PID algorithm were implemented. The overall scheme of the system and operating principle were described, and the block diagram of the hardware and software were designed. A interface of real- time monitoring system was proposed in this article. The system is running well and can meet users＇ needs better.
