摘要:
自從交通燈誕生以來，其內部的電路控制系統就不斷的被改進，設計方法也開始多種多樣，從而使交通燈顯得更加智能化。尤其是近幾年來，隨著電子與計算機技術的飛速發展，電子電路分析和設計方法有了很大的改進，電子設計自動化也已經成為現代電子系統中不可缺少的工具和手段，現在，交通控制更是趨向智能化方向發展，LED交通信號燈在持續發光、雨淋、灰塵等惡劣的氣候條件下，仍然能保持較好的工作性能，而且價格更低廉。本文主要通過西門子PLC 控制交通紅綠燈。

Abstract:
Since the birth of traffic lights, the circuit in its internal control system have continually been improved, also began to design methods varied, so that traffic lights become more intelligent. In particular, in recent years, with electronics and the rapid development of computer technology, electronic circuit analysis and design methods have greatly improved, electronic design automation has become a modern electronic system in an indispensable tool and means now, more traffic control Trend is the development of intelligent, LED traffic lights in the continuing luminescence, rain, dust and other adverse weather conditions, can still maintain good work performance and lower prices. In this paper, Siemens PLC control traffic through the traffic lights
