摘 要:目前,城市的交通压力日趋严重,针对高峰时段,车辆集中,设计出可变车道与信号灯控制系统,通过对车流量的实时检测,对上位机系统和PLC编写控制程序,设置变更车道的通行方向和时间以及红绿灯的时间控制,实现市内交通的远程实时监管。采用地感线圈实时检测十字路口的车流量,PLC根据车流量的变化调用相应的控制程序,实现对变更车道的通行方向和时间的调配以及交通信号灯时长的分配。该方案有远程监管和现场手动控制两个入口,现场的工作人员可以根据实际情况,实现手动调控交通信号灯的时长以及对变更车道的控制。在远程监管方式下,可根据全市的交通现状,对道路的交通状况实现全局管理和控制。提高道路的管控一体化水平。at present, the city' s traffi has become increasingly serious, in view of the rash hour, traffic concentration, design variable lane and light control system, based on the real-time detection oftraffic flows on the upper machine system and PLC control program, change lanes were available in the direction oftraffic and time and traffic control, realize remote real-time regulation of traffic in the city.The ground sense coil is used to detect the traffic flow at the crossroads in real time. The PLC calls the corresponding control program according to the change of traffic flow to realize the allocation of the traffic direction and time of changing lanes, as well as the allocation of the traffic signal length.This scheme has two entrances: remote supervision and manual control on the site. The site staff can manually control the length of traffic lights and control the changing lanes according to the actual situation.Under the remote supervision mode, the overall management and control of road traffic can be realized according to the traffic status of the whole city.We will improve the integration of road management and control.
