摘 要：現(xiàn)如今自動化、信息化程度越來越高，單片機的應(yīng)用領(lǐng)域也就越來越廣，成為人們生活不可或缺的一部分。隨著社會的發(fā)展、科技的進(jìn)步以及人們生活水平的逐步提高，各種方便于生活的自動控制系統(tǒng)開始進(jìn)入了人們的生活，以單片機為核心的電梯門系統(tǒng)就是其中之一。同時也標(biāo)志了自動控制領(lǐng)域成為了數(shù)字化時代的一員。它實用性強，功能齊全，技術(shù)先進(jìn)，使人們相信這是科技進(jìn)步的成果。它更讓人類懂得，數(shù)字時代的發(fā)展將改變?nèi)祟惖纳?，將加快科學(xué)技術(shù)的發(fā)展。由對射主動紅外探測器組成的電梯紅外光幕具有更智能，更易控制的特點。
通過對“電梯紅外光幕控制器”的研究和設(shè)計。本論文著重闡述了以單片機為主體，直流電機、轉(zhuǎn)速測量為核心的系統(tǒng)。
本設(shè)計主要應(yīng)用8051作為控制核心，直流電機、紅外傳感器等結(jié)合的系統(tǒng)。充分發(fā)揮了單片機的性能。其優(yōu)點硬件電路簡單，軟件功能完善，控制系統(tǒng)可靠，性價比較高等特點，具有一定的使用和參考價值。

The design of curtain controller with infrared in lift
Abstract：As it becomes more and more automatic and informational nowadays, the application of microcontroller also becomes more and more extensively. Progress of with the development of the 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’s life, will quicken the development of science and technology.
Through the research and design to the thing that "The design of curtain controller with infrared in electric 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 has certain use and reference value.
Keywords：Microcontroller，Electric door ，DC motor ，Infrared sensor
