不利天气高速公路路况车载采集系统研究

Vehicle Road Condition Information Collection System in Adverse Weather

分析了不利天气下道路安全状况评估参数及其影响因素,确定了车载路况采集系统的功能,设计了由道路能见度检测、道路环境温湿度检测、路面状况识别、路面微观形貌检测、路况数据定位与路况数据无线传输6个子系统以及检测车、电源系统等组成的路况检测系统,分析了系统设计中的一些关键技术。

This paper analyzed the evaluation parameters of road condition and the factors influencing them in adverse weather. The functions of vehicle road condition collection system were determined. On this basis, a system of road condition detection was designed including road visibility detection, road environment temperature and humidity detection, pavement condition recognition, pavement mierostructure detection, road condition data location and road condition data wireless transmission, detecting vehicle, power system, etc. Furthermore, some key technologies to implement this system were analyzed.
