A design of the automatic control system in fire intelligence monitors and fireproof rolling gate

Abstract

 Progress of with the development of society , science and technology and gradual improvement of people''s living standard, various kinds of help automatic control system in life begin to enter people''s 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 life, will quicken the development of science and technology.
 Is it use AT89C51 as core of controlling , LED lattice show chip , walk into electrical machinery ,smoke sensor and temperature sensor , electric potential system that device 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, have certain use and reference value.
