摘要
为应对当前高速公路大雾天气时预警信息存在的不足,设计了车载实时预警系统,该系统应用射频识别技术实现对高速公路前方雾况信息的实时预警,设置能见度检测仪与阅读器同步,通过后台数据处理中心对检测数据的处理,实现了对前方雾区距离的准确测量和雾区行车速度的计算,通过车载警示装置提醒驾驶员,提高了高速公路雾区行车的安全性。
It analyzes the disadvantages of forewarning information in tackling misty freeway, designs a real - time carborne forewarning system. This system uses RFID technology to forewarn anterior misty area in freeway, sets synchronization between visibility device and reader, and disposes the datum with data processing center, makes the accurate measure of the distance of anterior misty area and the calculate of driving velocity in misty area, finally alarms the driver. The application shows that the system improves the safety of driving on misty freeway.
