摘　　要：为了缓解城市交通拥堵等交通现状,研制了由欧姆龙PLC做下位机控制器,组态王做远程监控软件的双路口协调控制交通灯实验系统。该实验系统具有实时车流量检测、分时段控制、手动控制、无线遥控控制、急车通行功能。监控计算机通过局域网对交通路口进行远程监控。实验证明,该系统稳定性好,功能完备,人机界面友好,可减少堵塞现象和交通事故,具有很好实际应用价值。For the sake of reducing the traffic jams and accidents in the city, the authors have studied a signalized junction＇ s control experiment system to harmonize the two crossings which use Omron PLC as its lower computer controller and KingView as its upper computer controller. This system can detect the flow of the cars in the real time, control in the separate time, control with the hand movement, control with wireless and allow the exigency ear pass. The traffic crossing can be controlled remotely by LAN. Experiment proves it runs stably and functions well with friendly man-machine interface and it can reduce the traffic jams and accidents. It has certain practical value and reference value for actual application.
