As a background, Developing a control system of low cost automatic opening door based on single chip microputer, introduced the infrared sensor to detect the pedestrian, In this paper, we design control system of the automatic door based on single chip microputer. The system with 51 singlechip puter as the main body, dc motor, the entrance guard system as the core, achieve automatic control of automatic door, achieve to enter the automatic door of office in the outside by password, Within the infrared induction open the door automatically, Equipped with automatic door normally open, normally closed. Through single chip microputer program ,control current servo motor39。s forward and control the door of open and close current motor driven uses H bridge, give full play to the performance of the micro controller. Its advantage is simple circuit, software function is perfect, and reliable control system, high cost performance, has certain use and reference value.
