基于单片机的交通灯控制器的设计与实现
 摘要：近年来随着科技的飞速发展，单片机的应用正在不断地走向深入，同时带动传统控制检测日新月异更新。在智能检测、控制系统中，往往使用单片机作为一个核心部件来使用，然后配合具体硬件结构，以及针对具体应用对象特点的软件结合，加以完善。
 在车辆穿梭的十字路口，行人熙攘，如果没有有效控制极易出现混乱。但仅以传统方式或交警来指挥的话已不能满足当今城市交通的需要，因此需配备智能化的交通控制灯。交通信号灯控制方式很多，控制功能也分高中低等多级。由单片机控制的交通信号灯控制系统是单片机学习中极具典型的一项设计，同时也是极具实用意义的一项研究。本设计依托单片机技术，结合LED显示来构成一个中等功能的智能化的道路控制系统。为了系统稳定可靠采用了MAX706“看门狗”芯片，避免了系统因为死机而停止工作的情况发生。

Based on the design of the controler of traffic lights of single flat machine
Abstract: In recent years, with the rapid development of science and technology, the application of SCM is continuously to further, traditional control test rapidly updated. In the intelligent detection and control systems, often used as a core component chip, then to use with specific hardware structure, and the view of the specific application software, the object characteristics.
 At the intersection of cars, bustling, if no effective pedestrians, appear easily controlled. But only in a traditional way to directing traffic or words can not meet the needs of today's urban transportation, therefore with intelligent traffic control light. There are many ways to control traffic lights low high control functions and multi-level. The traffic light by single-chip microcomputer control system is controlled in learning is one of the most typical design, is also extremely practical significance to study. This design is relying on the single chip microcomputer, combined to form a LED display the function of intelligent medium road control system. In order to system is stable and reliable MAX706 adopted watch-dog chips, to avoid the system crashed and stop work because of the situation.
