The invention provides a road traffic signal lamp based on the Internet of Things. According to the technical scheme, the mechanical structure of the road traffic signal lamp is improved, and a two-way interaction pavement indication function is achieved based on an Internet of Things communication principle. Specifically, the signal lamp is designed to be of a stacked structure, the independent positioning mechanisms are additionally arranged layer by layer, the positioning mechanisms bear the searchlight, and by means of the two-degree-of-freedom movement function of the positioning mechanisms, light spots projected by the searchlight on the ground can be positioned at any position. On the basis, firstly, a comparison table is established between ground light spot coordinates and the corner of the positioning mechanism, then a fixed camera is used for collecting road surface pictures within the sight range of the camera, and all coordinate points are calibrated on the camera. According to the invention, the pit position can be indicated on site, the function can be flexibly achieved under the control of workers in a remote manner, and the function is not possessed by various roadinfrastructures at present, so that the road traffic signal lamp has outstanding technical advantages.

    本发明提供了一种基于物联网的道路交通信号灯。该技术方案对道路交通信号灯的机械构造加以改进,并基于物联网通信原理实现了双向交互的路面指示功能。具体来看,本发明将信号灯设计为层叠结构,逐层增设独立的定位机构,定位机构承载探照灯,利用其双自由度的运动功能,可将探照灯在地面上投射的光点定位置任一位置。在此基础上,首先在地面光点坐标与定位机构转角之间建立对照表,而后利用固定的摄像头采集其视线范围内的路面照片,并在其上标定全部坐标点。应用本发明,可在现场指示出地坑位点,而且可远程的、在工作人员控制下灵活实现,这一功能是目前各类道路基础设施均不具有的,因而具有突出的技术优势。
