随着经济的发展和人民生活水平的提高，自动门的应用也越来越广泛，它已经成为宾馆、超市等现代建筑所必备的，是建筑智能化水平的重要指标。自动门控制系统作为自动门系统的控制核心，决定了自动门系统的性能。国外生产的自动门控制系统性能比较优良，但是价格偏高；国内的同类产品虽然价格便宜，但是性能较差，故障率较高。本文研究一种基于AT89C51的自动门控制系统，功能强大，运行可靠，用户操作方便，而且成本适中，在市场上有较强的竞争力-With the economic development and improve the living standards of the people, automatic door applications more and more widely, it has become a hotel, supermarket, etc. necessary for a modern building, is building an important indicator of the level of intelligence. Automatic door automatic door control system as the core control system, determines the performance of automatic door systems. Foreign production of automatic door control system for excellent performance, but the high price While the domestic price of similar products, but poor performance, a higher failure rate. In this paper, AT89C51-based automatic door control system, powerful, reliable operation and user convenience, and the cost of modest, there is strong in the market on the competitiveness of
