摘要

在各式各样的霓虹点亮我们生活的同时，如何让色彩缤纷的广告灯更加的花样丰富成为了不论是商家还是学术界都十分关注的热题。传统的硬件仿真耗资大，仿真效果不突出。本设计采用了国内领先的单片机软件仿真技术，不但耗资小而且实现起来更为简便。

通过对Keil软件和Proteus软件的完美牵手，实现了广告灯的花样设计，八个LED发光二极管由上至下依次点亮然后花样闪烁循环。本设计还详细地介绍了由AT89C51集成块编程实现的控制电路，它完成了单片机控制广告灯功能，并给出了具体的硬件电路和相应的源程序。主要运用Keil软件和Proteus软件，Proteus软件主要完成了广告灯的硬件电路图的搭建，Keil软件主要完成了广告灯源程序的编写和编译任务，在Keil软件和Proteus软件的完美结合之下，实现了和硬件几乎无差的软件仿真。另外在完成本设计的同时考虑到基于单片机广告灯的实际应用问题，还在此基础上扩展，对大家更为熟悉的交通灯做了初步设计，搭建了基于AT89C51的交通灯的硬件电路图。无论是广告灯还是交通灯，对于我们的生活都有着千丝万缕的联系。由AT89C51集成块编程实现的控制电路可靠性、灵活性高，使用范围广，特别适合中小城市的交通灯、霓虹灯等的应用。而且，它对其他类似系统的开发具有一定的发展和借鉴意义。

Abstract

In all kinds of neon light up our life at the same time, how to make colourful ads light more pattern rich became both business or as academia are very concerned hot topic. The traditional hardware emulation cost big, the simulation results not outstanding. This design uses a domestic leading single-chip microcomputer software simulation technology, not only $small and realize rise more convenient.

Through the Keil software and Proteus software perfect in hand, realized the advertisement lamp pattern design, eight LED light emitting diode from up to down in light and then figure flashing cycle. This design is introduced in detail by AT89C51 integrated blocks for the programming of control circuit, it be completed single-chip microcomputer control advertising lamps function, and gives some specific hardware circuit and the corresponding source program. Mainly uses Keil software and Proteus software, Proteus software main completed advertisement lamp hardware circuit diagram, the construction of the Keil software main completed advertising light source program to compile and compile Keil software and mission in the perfect combination of Proteus software and hardware, realized under almost no difference to the software simulation. In the completion of this design consideration based on single-chip advertisement lamp practical problem, also based on extension of the more familiar to everybody, traffic light makes a preliminary design and built based on AT89C51 traffic lights hardware circuit diagram. Whether advertising light is still the lights, for our life are closely related. By AT89C51 integrated blocks for the programming of control circuit reliability, high flexibility, wide utilization, especially suitable for small and medium-sized city neon lights, such application. Moreover, it to other similar system development has certain development and significance.
