摘 要
随着改革的不断深入,社会主义市场经济的不断繁荣和发展,大中小城市都在进行亮化工程,通常都是利用广告流水灯来实现这一目的。广告灯的亮灭、闪烁时间及流动方向等均可以通过单片机来达到控制的要求。本设计是通过AT89C52单片机控制由35个LED组成的“XYSF”四个字母从左到右依次点亮然后花样闪烁循环,实现了广告灯的花样变化。本文介绍了由AT89C52集成块实现的控制电路,并给出了具体的硬件电路和相应的源程序。由于AT89C52集成块编程实现的控制电路可靠性、灵活性高,使用范围广,特别适合中小城市广告灯的应用。本控制系统结构简单、成本低、功能可靠、可移植性强,通过程序的变化,可以实现灵活多样的流水显示方案。通过单片机的控制,我们可以把城市的夜晚装饰的更漂亮。

Abstract
With the deepening of the reform, the increasing prosperity of the socialist market economy and the development of cities and towns during the lighting project, usually advertising water lights to achieve this purpose. Bright advertising lights off, flashing time and the flow direction, all through the microcontroller to achieve the control requirements. This design is composed by 35 LEDs on AT89C52 XYSF four letters from left to right to light and then the pattern blinking cycle, the pattern changes in the advertising lights. This article describes the control circuit, realized by AT89C52 Manifold and specific hardware circuit and the corresponding source code. Because the AT89C52 Manifold programming of the control circuit reliability, high flexibility, the use of a wide range, especially for small and medium-sized cities the application of the advertising lights. The control system is simple structure, low cost, reliable functionality, portability can be achieved through changes in the program, flexible water display. Through the control of the microcontroller, the night decoration of the city more beautiful.
Keywords: advertising light; on AT89C52; the LED
