A safe and intelligent traffic light warning device is composed of an ultrasonic detection circuit, a distance and speed calculation circuit, a warning and display circuit and a power supply. The device has the beneficial effects that the traffic efficiency of the intersection is greatly improved and the complexity of the signal lamp at the intersection is reduced only aiming at the red light running phenomenon of vehicles on the opposite same-side lane. The vehicles running the red light are detected by using ultrasonic waves, so that unnecessary interference on the vehicles is avoided, and traffic accidents are reduced. The device is installed on an intersection signal lamp pole, is not liable to be damaged, is not interfered by vehicle passing, and guarantees the durability of the warning and prompting effects. The system is perfectly embedded with various existing traffic light systems, does not cause interference to the existing traffic light systems, and is beneficial to popularization. The manufacturing cost is low, the manufacturing is simple, all operations are automatically completed in all directions, the working time is long, and human intervention is not needed.

    一种安全智能红绿灯警示装置,由超声波检测电路、距离和速度计算电路、警示和显示电路、电源组成。有益效果是:只针对对向同侧车道车辆的闯红灯现象,大大提高了路口的通行效率,减少了路口信号灯的复杂程度。利用超声波对闯红灯车辆进行检测,不会对其造成不必要的干扰,减少了交通事故的发生。安装于路口信号灯杆上,不易损坏,不会受车辆通行的干扰,保证了警示和提示效果的持久性。与现有的各种红绿灯系统完美嵌合,不对现有的红绿灯系统造成干扰,利于推广。造价低廉,制作简单,全方位自动化完成所有操作,工作时间长,不需要人为干预。
