摘　　要：为给管养单位提供实时的高速公路桥面路况信息,使管养单位能有目的地对桥面交通进行保养和维护,提出在桥面布设无线传感器来检测桥面的温湿度信息、倾斜度信息、结冰信息、振动信息和位移信息等,并采用LoRa(Long Range Radio)无线传输技术将采集到的数据信息汇聚到一体化机柜中。利用视频事件检测器、毫米波雷达来监测桥面的交通事故和拥堵情况,并将这些信息同无线传感器采集到的数据信息一起汇聚到一体化机柜中,再通过沿高速公路铺设的主干光缆传输至监控分中心工作站,为工作人员提供实时的交通信息,同时采用LED(发光二极管)可变信息情报板向来车司机显示桥面的路况信息。该方案能够有效协助工作人员监测桥面的路况信息,也能提醒来车司机前方桥面路况,提高驾驶的安全性。In order to provide real-time highway bridge deck road condition information for the custody unit,so that the custody unit can purposefully maintain and maintain the bridge deck traffic. In this paper,it is proposed to deploy wireless sensors on the bridge deck to detect the temperature and humidity information,tilt information,icing information,vibration information,and displacement information of the bridge deck,and use LoRa wireless transmission technology to gather the collected data information into an integrated cabinet. The use of video event detectors,millimeter wave radar to detect traffic accidents and congestion on the bridge deck,and gather these information together with the date information collected by the wireless sensor into an integrated cabinet,through the main cable laid along the line to the monitoring sub-center workstation for display,to provide real-time traffic information for the staff,and the use of LED variable information board to the oncoming drivers to display the road condition information of the bridge deck,so that the drivers who are about to enter the bridge deck know the road condition information of the bridge deck. The program can comprehensively monitor the road condition information of the bridge deck,and can also alert the staff and the driver of the car,effectively improving the safety of driving.
