1.电子琴功能 用实验板上K1~K7作为电子琴的7个按键，每个按键对应一个音符要求当按下其中一个按键，就通过P2.5口输出对应频率信号使蜂鸣器发出特定音符声音。 2.乐曲演奏 若按下K8键，完成自动弹奏“送别”歌曲。 -1. Organ function of the experimental board K1 ~ K7 as the organ of the seven buttons, each button corresponds to a note of which require that when the press of a button, on the adoption of P2.5 port output frequency signal corresponding to a specific note to the buzzer sounds . 2. Music playing, if pressed K8 button to complete the auto-play " Farewell" songs.

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
