摘要
针对现行交通灯在联控与智能化管理方面多存在的不足,进行改善并且通过设计实现终端控制的功能,通过使用三菱CC-LINK实现多路口的联控管理,以弥补现行交通灯设置绿波带所存在的比较大时间差的缺陷、以及无法实现多路口同时控制的缺陷;利用三菱Q系列PLC进行编程实现单路口智能控制,使得单路口交通灯能够根据不同的路况自动改变红绿灯时间以保证路况管理最优化;使用人机界面实现终端总控,使得在控制室实现终端总控以及监控路口交通灯运行状况。
For the existing traffic lights at the joint control and intelligent management of multiple deficiencies,improvement and implementation through the design of the terminal control functions,by using the Mitsubishi CC-LINK multi-joint control management at road junctions in order to compensate for the existing traffic lights green wave with the existence of relatively large time difference of the defect,as well as multi-junctions can not be achieved simultaneously control deficiencies;the use of Mitsubishi Q Series PLC is programmed to achieve a single intersection intelligent control,allowing a single junction traffic lights to automatically change according to different road conditions to ensure that the traffic lights time traffic management optimization;the use of man-machine interface to achieve the overall control terminal,making the terminal in the control room to achieve the overall control and monitoring operational status of traffic lights at road junctions.
