The invention discloses a road condition warning device and a warning method thereof. The road condition warning device comprises a road condition detection circuit, a communication circuit and a control circuit. The road condition detection circuit outputs a detection light beam within a detection distance of the street lamp. The control circuit relatively controls the display mode of the street lamp according to the detection result of the road condition detection circuit. When the detection light beam of the road condition detection circuit is blocked and lasts for more than a reference time, the control circuit obtains rear blocking information through the communication circuit and calculates a rear blocking total distance according to the rear blocking information. When the rear blocking total distance is smaller than the ending distance, the control circuit controls the street lamp to be displayed in a warning display mode. When the rear blocking total distance is larger than the ending distance, the control circuit controls the street lamp to be displayed in a normal display mode.
一种路况警示装置及其警示方法。其中路况警示装置包括路况检测电路、通信电路及控制电路。路况检测电路在路灯的一检测距离内输出一检测光束。控制电路根据路况检测电路的检测结果相对控制路灯的显示方式。当路况检测电路的检测光束被阻挡且持续超过一基准时间时,控制电路通过通信电路取得一后方阻挡信息,并根据后方阻挡信息计算一后方阻挡总距离。当后方阻挡总距离小于结尾距离时,控制电路控制路灯显示于一警告显示模式。当后方阻挡总距离大于结尾距离时,控制电路控制路灯显示于一正常显示模式。
