高速公路团雾预警与主动诱导系统研究

Research of agglomerate fog warning and active induction system for highway

团雾天气对高速公路行车具有重大的安全隐患。当前已有的各类团雾监测设备功能单一,无法构成完整的雾区监测及安全引导系统,所以研究一种完整的高速公路团雾预警与主动诱导系统就显得尤为必要。该系统通过主动诱导模块、团雾监测模块以及基于ZigBee和射频433技术的通信模块三者的相互结合,实现对高速公路团雾气象条件的准确监测,并且可以通过道路轮廓主动发光诱导标识指示车辆在低能见度条件下安全通过。该系统经实际道路安装测试具备较强的实用性,可有效减少因低能见度而导致的道路交通事故发生概率。

The agglomerate fog is a major safety hazard for highways.The current existing equipment of detecting agglomerate fog only have a simple function,so that those can＇t form a complete system of fog area monitoring and safety guidance,so the research of a complete agglomerate fog warning and active induction system for highway is particularly necessary.The system realizes the accurately monitoring of meteorological conditions of agglomerate fog through the active induction module,agglomerate fog monitoring module and communication module based on the technology of ZigBee and radio frequency 433.And it can be used to indicate the safe passage of the vehicles under the low visibility condition through the active luminescence identification of road contour.The system is more practicable by the practical road installation test,which can reduce the probability of road accidents caused by low visibility.
