The Automatic Door Control

System Based On SCM

Abstract

Along with society's development, the technical progress as well as the people living standard's gradual enhancement, automatic valve starts to enter people's life. It is not only indispensable for hotels, supermarkets, banks and other modern architecture, but also become an important indicator of the level of construction of intelligent. There is beautiful, generous,windbreak, dustproof, lower noise. Meanwhile it is convenient for people to access. And it facilitate the management, enhance the safety. Its usable, he 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. Automatic control system is the heart of the design, and the measure of the important indexes, the manufacture level. Also, it gradually toward large-scale, complicated and intelligent direction.

This design mainly 8052 takes the control core using the monolithic integrated circuit, direct current 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.
