毕业设计 基于单片机的交通灯无线控制系统设计.doc

摘　要 城市道路交通自动控制系统的发展是以城市交通控制技术为前导，与汽车工业并行发展的。在其各个发展阶段，由于交通的各种矛盾不断出现，人们总是尽可能地把各个历史阶段当时必威体育精装版科技成果应用到交通自动控制中来其中包括如计算机技术，通信技术和自动化技术的高度系统提供更好的性能和稳定性高，可在城市和农村地区的十字路口实现。 本文利用先进的单片机技术和无线遥控技术，发展城市道路交通车协调控制系统，能适应我国情。 在设计中我尽量考虑紧急情况发生，操作者可以使用遥控器来控制交通灯专用车辆优先，对此，尤其是在城市道路交通车通常有大流动良好的优势。该系统 Abstract With the economy development and improvement of peoples’ life, the number of vehicles has increased rapidly. There are more and more several traffic congestion on highway, street and in the city. The traffic congestion can result in time delay, increase traffic accident, environmental pollution and waste of oil. The traffic congestion becomes the “bottleneck” of the development and national economy. The modern traffic control technology, which includes high technologies such as computer technology ,communication and automation technology gives better performance of the system and high stability can be achieved in the crossroads of urban and rural areas. If coordination control problems of urban traffic truck roads can be solved, the urban traffic congestion can be reduced. So this paper directs energies to use advanced Single chip microcomputer technology and wireless remote control technology to develop the urban traffic truck roads coordination control system which can fit with the situation of our country. In design I try to consider emergency situations which operator can use remote control to control traffic light for special vehicles priority, this have good advantage especially in the urban traffic truck roads which usually have heavy flow. The system design is cheap and has a good control effects. So far, the small scaled single chip microcomputer traffic control system is a kind of advanced traffic control system. The method of realizing is, first give out a optimize project of the control object the crossing’s vehicle, then realizes with single chip computer and electronic circuit. This design primarily adopts the MCS-51 series single chip microcomputer and wireless control techn
