Progress of with the development of the society, science and technology and gradual improvement of peoples living standard, various kinds of help automatic control system in life begin to enter peoples life, the system of automatically-controlled door taking one-chip computer as the core is one of them. Indicate too that the automatic controlled field became a member in digitized era at the same time. Its practicability is strong, multiple functional, modern techniques, make people believe this is an achievement of scientific and technological progress. It lets the mankind understand even more, the development in digital era will change human’s life, will quicken the development of science and technology. Through the research and design to the thing that the system of single chip controlled auto-door, I have written the computer and controlled the systematic thesis of automatically controlled door meticulously. Thesis this is it rely mainly on one-chip computer to explain emphatically, DC motor and the measure of rotate speed central systems. It is uses 8051 as core of controlling, the DC motor, infrared sensor and electromagnetic switch combine together mainly to design originally. Give full play to the performance of the one-chip computer. Its advantage hardware circuit is simple, the software is with perfect function, the control system is reliable, higher characteristic of the sex price, and it
