摘要：随着城市建设的不断发展、经济体制的不断改革以及人们生活水平的提高,自动门的使用也越来越广泛,它已经成为现代建筑的基本元素之一,而酒店,超市,是构建智能水平的重要指标。自动门系统的性能被决定是由于自动门控制系统控制着整个自动门。性能比较好自动门控制系统都不是由我们自己的国家生产的，因而它的价格较高，我们国家的这种商品价格便宜,但是它的性能却比较差,尤其是故障发生的概率也很高。在本文中,我们研究的是一套基于STC89C52单片机的自动门控制系统,它具有强大的功能，运行起来安全可靠,用户操作便利,而且价格适中,具有较强的竞争力。STC公司推出的STC89C52是一种集低功耗、高性能等优点于一身的微控制器，拥有在系统可编程Flash的8K存储器，因此为我们的设计提供了灵活、高效的解决方案。另外，本文还采用了五线四相步进电机使得电机转速、停止的位置不受负载变化的影响，加上步进电机没有累积误差只受周期性影响等特点，使得开发过程更加顺畅,提高了系统的灵敏度和可靠性,达到了系统设计的预期要求。

Intelligent control system of automatic door based on 51 single chip microcomputer

Abstract：With the development of city construction, economic development and the improvement of people's living standards, the use of automatic door is more and more widely, it has become one of the basic elements of modern buildings and hotels, supermarkets, is an important index to construct the intelligent level. The automatic door control system is the control core of the automatic door system, and therefore decided to the performance of the automatic door system. Because the performance of the automatic door control system of other countries is better, so the price is high, while our nation's similar products, although the price is cheap, but the performance is poor, and the failure rate is very high. In this paper, we study a STC89C52 based microcontroller Automatic door control system, it has powerful function, safe and reliable operation, the user operation is convenient, and the price is moderate, with strong competitiveness of.STC company launched STC89C52 is a set of low power consumption, high performance and other advantages of a micro controller, with 8K in system programmable Flash memory, so for us the design provides flexible and efficient solutions. In addition, this paper also uses five line four phase stepper motor to make the motor speed and stop position is not affected by the change of load, and stepper motor without accumulated error only by the cyclical impact, makes the development process more It can improve the sensitivity and reliability of the system, and meet the requirements of the system design
