人体热辐射控制交通信号灯设计

Design of Traffic Light Controlled by Heat Radiation of Human Body

针对有交通信号灯控制的道路交叉口进行行人流量调查,研究通过人体热辐射能够自动控制并以热红外传感器为技术核心的LED交通信号灯的转换时间,使得当交叉路口人流达到指定数量时交通信号灯能够自动转换时间,自动放行交叉口人流而暂时阻止车辆通行。

This paper investigates pedestrian flow at signalized intersection, and studies the conversion time of LED traffic light controlled by heat radiation of human body and taking the thermal infrared sensor as the core technology. It makes the traffic light converse time automatically so that the pedestrian flow can be released automatically and vehicle flow can be stopped temporarily when the pedestrian flow at intersection reaches the specifled number.
