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

AV系统数字调谐PLL频率合成器的单片机控制 文章利用LC7218PLL频率合成器在AV领域的电调谐功能,提出了一个TV/FM/AM全景接收机设计方案,重点设计分析了LC7218与单片机之间的I/O数据结构,显示了它优良的性能。-AV system PLL digital tuning of the single-chip frequency synthesizer to control the use of article LC7218PLL frequency synthesizer in the AV field of electrical tuning function, a TV/FM/AM panoramic receiver design programs that focus on design and analysis of the LC7218 and MCU between the I/O data structure, demonstrated its excellent performance.

该设备是一款基于AVR mega16L单片机的电子书阅读器，它除具有传统的阅读电子资源功能外，还能通过PS2接口与PC键盘连接，使用普通PC键盘输入信息，进行文本录入；使用LCD12864液晶作为显示器，它还可以用VB专门为之编写的下载软件通过串口下载TXT格式的文本资源。电子书资源存储在AVR公司生产的AT45DB021B闪速存储器，它有2M存储空间，可满足一般用户需要，当然也可升级为大容量存储器。 该设备功能强大，将电子书阅读器发挥到了极致，能满足用户特殊需要。 -The device is a single chip based on the AVR mega16L e-book reader, which in addition to the traditional functions of reading electronic resources, but also through the PS2 interface to connect with the PC keyboard, use an ordinary PC keyboard input information, the text input use LCD12864 LCD as a display, it can be prepared by specialized VB download software through the serial port to download TXT format text resources. E-book resources are stored in the AVR produced AT45DB021B flash memory, it has 2M storage space to meet the needs of general users, of course, can also be upgraded to a large-capacity memory. The device is powerful and will play an eBook reader to the extreme, and to meet the special needs of users.

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态。-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current lighting condition.
