摘　　要：文中基于边缘计算等高端技术,提出设备信息的本区域化路口智能交通灯IoT方案,以此完成路口设备的边缘连接与信息化管理。通过对系统商品模块的设计研发语言路口的具体检测方式,验证电力线载波物联与边缘智能管控的可行性,为完成智慧路口的信息互通互联与管控提供可参考依据。另外,针对我国城市交通堵塞的情况,对传统的固定用时下的交通状况进行改善,提出一种多元化的作业模式下的PLC智能交通灯的控制系统,通过预埋传感设备对路段上车流量实施监督与控制,根据车流量的改变情况来控制交通灯。结果表明,通过声音检测设备对特殊车辆实施检测,可实现车辆的迅速通信。通过对PLC交通灯进行控制,能够减少车辆的等待时间,并大幅度提升十字路口的通行能力。The intelligent traffic light IoT(Internet of Things) scheme of equipment information at local intersection is proposed on the basis of high-end technologies such as edge computing,so as to complete the edge connection and information management of equipments at intersection. The specific detection mode of the language intersection is researched by designing the system commodity module,and the feasibility of power line carrier IoT and edge intelligent control is proved,which can provide a reference basis for completing the information interconnection and control of smart intersections. In allusion to the urban traffic jam in China,a PLC(programmable logic controller)intelligent traffic light control system in diversified operation mode is proposed to improve the traffic condition at the traditional fixed time. The embedded sensing equipment is used to supervise and control the traffic flow on the road section,and the traffic lights are controlled according to the change of traffic flow. The results show that the sound detection equipment can be used to detect the special vehicles to realize the rapid communication of the vehicles. By controlling the PLC traffic light,the waiting time of the vehicles is reduced,and the traffic capacity of the intersection is improved greatly.
