The invention discloses a wireless wide and narrow band combined highway guardrail collision data acquisition and transmission method. The method comprises the following steps of S1, data acquisition,S2, data processing,S3, processing result sending,S4, entering a narrowband convergence layer,S5, sending to a broadband convergence layer,S6, data convergenceand S7, access layer gateway. A sensing layer, the narrowband convergence layer, the broadband convergence layer and the access gateway layer are combined,accessing and controlling a special communication network of a traffic management department are carried out, the functions of sensing, collecting and transmitting guardrail data are achieved, the system has the function of detecting energy on the highway pavement and during collision,the real-time state of a highway network can be sensed and positioned through the wireless communication transmission function, the traffic transportation management function is enhanced, and the efficiency of safety management and highway emergency treatment is improved.
本发明公开了一种无线宽窄带结合的公路护栏碰撞数据采集与传输方法,包括以下步骤:S1:数据采集S2:数据处理;S3:处理结果发送S4:进入窄带汇聚层S5:发送到宽带汇聚层S6:数据汇聚S7:接入层网关;本发明中通过感知层、窄带汇聚层、宽带汇聚层和接入网关层的结合,跟交管部门专用通信网接入并控制,实现了对护栏数据感知采集和传输功能,具备对公路路面和碰撞时的能量检测功能,利用无线通信传输功能,可以对公路网的实时状态进行感知和定位,增强了交通运输管理功能,提高了安全管理和公路应急突发处理的效率。
