Abstract Abstract
Nowadays automation, informationization level is higher and higher, MCU application field is becoming more and more widely, become an indispensable part of people's life. With the development of the society, the progress of science and technology and the improving of people's living standard, all kinds of convenience in life start into the automatic control system of people's lives, with the single chip processor as the core of the automatic door system is one of them. Also marks the automatic controlled field became a member of the digital age. Its practicability is strong, the function is all ready, technology advanced, make people believe it's the result of scientific and technological progress. It is more to understand people, the development of the digital era will change human life, will speed up the development of science and technology.
This paper focuses on the design with 89C52 as the main body, pyroelectric infrared sensor, dc stepper motor as the core of automatic door control system, etc. It give full play to the performance of the microcontroller, the advantages of hardware circuit is simple, software function is perfect, reliable control system, the characteristics of high cost performance, has certain use and reference value.
Keywords automatic door; single chip microcomputer; stepping motor;
