The invention discloses a road surface icing condition judgment method based on tire road friction voiceprints. The method comprises the steps that S1, friction sounds of tires and a road surface generated when a vehicle passes through the road surface are collected through recording equipment; s2, pre-processing the voiceprint signal of the friction sound; s3, performing model judgment according to the preprocessed voiceprint signal, and judging whether the road is frozen or not; and S4, generating an icing alarm signal according to a model judgment result. According to the road icing monitoring system and method, the voiceprint features of the collected sound data are analyzed and judged, real-time monitoring of road icing is carried out according to the voiceprint feature difference in different states, and full-time global monitoring of the road condition can be rapidly and accurately achieved at low cost.

    本发明公开了一种基于胎路摩擦声纹的路面结冰状况判断方法,包括:S1、通过录音设备采集车辆驶过路面时产生的轮胎与路面的摩擦声;S2、对所述摩擦声的声纹信号进行预处理;S3、根据预处理的声纹信号进行模型判断,判断道路是否结冰;S4、根据模型判断结果,生成结冰警报信号。根据本发明,通过对收集到的声音数据进行声纹特征进行分析判断,依据不同状态下声纹特征差异进行路面结冰的实时监测,可以快速、准确、低成本的实现道路状况的全时全域监测。
