The invention relates to the technical field of road collapse detection, in particular to a road collapse detection method and device. According to the technical scheme, equipment is installed below rearview mirrors on the two sides of a vehicle, and the interior of the equipment comprises four modules including a laser emission module, a laser detection module, a GNSS speed measurement module and a road collapse judgment module. The laser emission module receives a sending instruction sent by the road collapse judgment module and emits laser to the front of a road, the laser falling point may be about 100 m in front of a vehicle, and the value can be adjusted according to different installation inclination angles of the laser emission module; according to the invention, the laser pulse repetition frequency can be set according to the following formula: 0.14 v/delta < = fr < = 0.28 v/delta. The device is installed on the rearview mirrors on the two sides of the vehicle, can continuously detect whether the road ahead collapses or not in the high-speed running process of the vehicle, and can give an early warning to a driver in time if collapse is found, so that the tragedy of vehicle falling is avoided.

    本发明涉及道路塌陷检测技术领域,尤其涉及一种道路塌陷检测方法及其装置。其技术方案设备安装在车辆的两侧后视镜下方,内部包括四个模块:激光发射模块、激光检测模块、GNSS测速模块和道路塌陷判断模块;激光发射模块接收道路塌陷判断模块发来的“发”指令,向道路前方发射激光,激光落点可能在车辆前方100m左右,该值根据激光发射模块安装倾斜角度不同会有所调整;本发明建议激光脉冲重复频率可以按下式设定:0.14v/δ≤fr≤0.28v/δ。本发明安装在车辆两侧后视镜上,可以在车辆高速行进中,持续检测前方道路是否塌陷,若发现塌陷,能够及时给予司机预警,避免车辆坠落的悲剧发生。
