 Abstract
     Along with society's development, the technical progress as well as the people living standard's gradual enhancement, each kind of convenience started in the life automatic control system to enter people's life, take the monolithic integrated circuit as the core automatic valve system was one of them. Simultaneously had also symbolized the automatic control domain has become digitized time one. Its usable, the function is complete, the technological advance, causes the people to believe that this is the advance in technology achievement. It lets the humanity understand that Digital Age's development will change humanity's life, will speed up the science and technology the development. through right “control automatic valve system” the research and the design, have composed the control automatic valve system paper carefully. The present paper elaborated emphatically take the monolithic integrated circuit as the main body;the sensor and step-by-steps the electrical machinery for the core system.
 This design mainly 8051 takes the control core using the monolithic integrated circuit, step-by-steps system which the electrical machinery, the pyroelectric infrared sensor, the potentiometer unify. Has displayed monolithic integrated circuit's performance fully. Its merit hardware circuit is simple, the software function is perfect, the control system is reliable, the performance-to-price ratio higher characteristic, has certain use and the reference value.
key words: The monolithic integrated circuit  step-by-steps the electrical machinery sensor
