The embodiment of the invention provides an early warning system for preventing chain traffic collision on a highway. The early warning system comprises an optical cable, a plurality of optical fiber sensors, a plurality of infrared thermal monitors, a first controller and a plurality of early warning devices, the plurality of optical fiber sensors, the plurality of infrared thermal monitors and the plurality of early warning devices are respectively connected with the first controller through optical cables; the optical fiber sensors determine a first position where the stress on the optical cable changes and send the first position to the first controller; the infrared thermal monitors collect infrared thermal images and send the infrared thermal images to the first controller; the first controller determines a second position where traffic collision occurs according to the first position and the infrared thermal images, determines a first target early warning device from the plurality of early warning devices according to the second position, and sends first early warning information to the first target early warning device; and the first target early warning device outputs the first early warning information sent by the first controller. In this way, early warning can be given out to follow-up vehicles, so that continuous collision of the vehicles is prevented.

    本申请实施例提供了一种高速公路上防止连环撞车的预警系统,预警系统包括光缆、多个光纤传感器、多个红外热监测器、第一控制器和多个预警器;多个光纤传感器、多个红外热监测器和多个预警器分别通过光缆与第一控制器连接;光纤传感器确定光缆上应力发生变化的第一位置,并将第一位置发送给第一控制器;红外热监测器采集红外热图像,并将红外热图像发送给第一控制器;第一控制器根据第一位置和红外热图像,确定发生撞车的第二位置,并根据第二位置,从多个预警器中确定第一目标预警器,向第一目标预警器发送第一预警信息;第一目标预警器输出第一控制器发送的第一预警信息。这样,能够对后续跟进车辆发出预警,以防车辆连环碰撞。
