Abstract

With the development of society, the progress of science and technology and people’s life level gradually improve, all sorts of convenience life automatic control system began to enter into people’s lives, the automatic door systems with SCM as the core is one of them. This paper introduces the design of metro automatic door, based on single chip microcomputer as the subject in this system, dc motor, speed measurement as the core, realize the automatic control to iron.

This design is mainly used the 8051 as control core, combin of DC motors, infrared sensors, magnetic switch.Making full use of the microcontroller performance. Through the microcontroller program control the dc servo motor foreward or inversion, thus control the door open or close; and close Dc motor driven adopt H bridge.Its advantage is the circuit is simple, software’s function is consummation, the control system is reliable, cost-effective is high,it has a certain use and reference value.

Keywords: Metro automatic door；DC motor；Infrared sensors；Speed measurement
