基于三菱FX2N型PLC的十字路口交通灯控制系统设计

Design of Crossroads Traffic Signal Lights Control System Based on Mitsubishi FX2N PLC

在繁华热闹的城市中,信号灯对保障交通顺畅起到非常重要的作用。常见的交通信号灯有主干道路上十字路口交通信号指示灯,以及为保障行人横穿车道的安全和道路的畅通而设置的人行横道交通信号指示灯。该设计基于PLC的步进顺控指令利用时序图的方法设计一个交通灯控制系统。该系统不仅简单实用、性价比高、易于维修,还能够对交通灯进行自动化控制,对于提高现代交通系统的流畅性具有非常现实的意义和作用。

In a bustling city, signal lights play a very important rolein making traffic smooth. The common traffic lights are the traffic signal lights at the crossroads on the trunk road and the crosswalk traffic signal lights set up to ensure the safety of pedestrians crossing the lane and the smooth flow of the road. The design is based on the step sequence control instruction of PLC and uses the method of timing diagram to design a traffic light control system. The system is not only simple for use, cost-effective, easy to maintain, but it can also automatically control traffic lights, thereby has a very practical significance and role in improving the flow of modern traffic system.
