Temperature signal chip DS18B20 collection by the temperature, with digital signal transmitted to the form of single chip microcomputer; Pressure by level sensor signal pressure of real time data collection, with an analog form transfer to the single chip microcomputer, microcontroller through the A/D conversion, converted into digital signals, calculation and treatment will temperature, pressure, water level information displayed in the LCD monitor, the paper introduces the hardware part of the control system, including: temperature detection circuit, temperature control circuit, pressure detection circuit, pressure control circuit and other single chip microcomputer interface circuit. The paper also introduces software design part, here the modularized structure programming. Software is mainly three parts: the main program, keyboard interrupt and key processing program, prearcing interruption program. The other one XieZi programs include: temperature signal processing program, show program, PID processing procedure, etc. This system can to the boiler temperature and water level of the full automation control, n
