摘要
近年来,随着的提高,车成为了我们日常生活中不可或缺的交通工具。在车辆日益增多的情况下要保证交通秩序有条不紊,就必须合理的设置交通灯。单片机具有小巧灵活,成本低,易于产品化,可靠性好,易扩展和具有通讯功能等卓越的性能,应用越来越广泛和深入。利用单片机来控制交通灯,具有安全可靠,控制操作灵活方便等各方面的优势。
本文设计的城市交通灯是基于STC89C516RD+单片机的系统,可以实现实际的道路交通灯的全部功能。本设计系统可以分为以下几个模块:按键控制模块,车辆指示灯LED模块,人行道指示LED模块,时间指示数码管模块。考虑到突发情况,本系统还设置了手控模式,按下手控按键,某一方向可以强制通行。在设计的过程中,所有模块的程序都是先用KEIL编程软件写出来,然后在PROTUES软件上进行仿真调试后再在硬件上进行调试。本系统设计周期短,可靠性高,实用性强,操作简单,维护方便,扩展功能强。
关键词:交通灯;单片机;编程;仿真
Abstract
In recent years, with the improvement of the national standard of living,the car has e an indispensable transport in our daily the increasing of vehicles,if we want to ensure the traffic order methodical,we must set of traffic lights chip puter has the advantages pact and flexible,low cost, easy-to-productization, excellent reliability, easy to expand and munication these superior performances,application of chip puter has been more and more widely and traffic lights controned by chip puter has the advantages of safe and reliable ,flexible and convenient control operations and other advantages.
In this paper,the design of city traffic lights is based on STC89C516RD+ puter, it can achieve all of the features of the actual road traffic lights. The design of the system can be divided into the following modules: button control module, the vehicle indicator LED module, sidewalk indication LED dot module, time indicates the digital tube control module. Take into account unforeseen circumstances, the system also set a manual mode, press manual control keys, one direction can force passage. In the process of doing this design, all modules of the program are write by the KEIL programming software first,and then simulation debugging in the PROTUES software and hardware debugging the last. The system design cycle is short,and it has the advantages of high reliabilit
