摘要:红绿灯（交通信号灯）是以规定时间交互更迭的光色讯号，设置于交岔路口或其它特殊地点，用以将道路通行权指定给车辆驾驶人与行人，管制其行止及转向的交通管制设施。以红、黄、绿三色灯号或辅以音响，指示车辆及行人停止、注意与行进。在1868年12月10日，信号灯诞生于英国，英国机械师德哈特于1868年设计了红、绿两色的煤气交通信号灯，由一名手持长杆的警察通过牵动皮带来转换灯的颜色。可惜的是，这盏灯的历史只有23天，中断的原因是煤气灯突然爆炸使一位警察殉职。第一盏交通灯黯然退场。时间的流逝，随着科学的电子工业的发展和技术的日益成熟的交通灯1914年，克里夫兰市率先在街道中恢复交通信号灯，随后纽约、芝加哥等城市也开始出现。这时的交通信号灯已从煤气进化为电气，这与现代的交通信号灯已经没有多少差距，除了信号灯本身，美国人还完善了信号控制系统。随着红绿灯的普及，各式各样的人性化的创意红绿灯也在各国层出不穷。自助红绿灯、触摸红绿灯、语音红绿灯等接连出现。图为2004年，安徽合肥首个“触摸式红绿灯”，交警在路口普及这种新型红绿灯的使用方法。红绿灯作为城市道路交通资源的分配器，科学的设置才是确保有序交通秩序的应有之义。然而，红绿灯设置不合理，或维护不当现象时有发生，甚至造成严重的交通事故。所以本课题就多功能交通灯做研究设计。70692

Design of multifunctional traffic light based on Proteus

Abstract：The traffic lights (traffic lights) is based on the color signal time alternately, arranged on the fork or other special places, the road traffic right assigned to vehicle drivers and pedestrians, the behavior control and steering traffic control facilities. With red, yellow, green or light signals, the vehicles and pedestrians are stopped, noticed and marched. In December 10, 1868, the signal was born in the UK, British engineers? Hart designed gas traffic lights red, green and white in 1868, by a hand pole police by pulling belt to the light color conversion. Unfortunately, this lamp only has a history of 23 days, the disruption was caused by a sudden explosion of gas police killed. The first traffic lights went out sadly. The passage of time, along with the electronics industry science and technology development of increasingly sophisticated traffic lights in 1914, Cleveland, the first to restore the traffic lights in the streets, followed by New York, Chicago city also began to appear. The traffic lights have evolved from gas to electricity, which has little to do with modern traffic lights. Besides the lights themselves, Americans have perfected the signal control system. With the popularity of traffic lights, a wide range of humanized creative lights are also emerging in many countries. Self service traffic lights, touch lights, speech lights, etc. appear one after another. Pictured in 2004, Anhui, Hefei's first "touch type traffic lights", traffic police at the intersection to popularize the use of this new traffic light. As the distributor of urban road traffic resources, traffic lights are the proper way to ensure the orderly traffic order. However, the traffic lights are unreasonable or improper maintenance, and even cause serious traffic accidents. Therefore, the subject of intelligent traffic lights do research and design.
