The invention belongs to the field of ETC monitoring, and discloses a vehicle monitoring method under the condition of electromagnetic interference. The method comprises the following steps of: 1, reading a license plate number of a vehicle and an equipment number of OBU equipment or a card number of a CPC card through a camera and RSU equipment which are erected on the same portal frame of a highway network; 2, sending the license plate number read by the camera to a server, and obtaining the equipment number of the OBU equipment or the card number of the CPC card corresponding to the licenseplate number from the server; and 3, searching and judging whether the equipment number or the card number obtained in the step 2 exists or not from one or more equipment numbers or card numbers readby the RSU equipment on the same portal frame where the camera is located within a preset time period, and if not, sending alarm information. Meanwhile, the invention further provides a road networkmonitoring system.
本发明属于ETC监测领域,其公开了一种具有电磁干扰的情况下的车辆监测方法,包括如下步骤:步骤1:通过高速路网的同一龙门架所架设的摄像头和RSU设备读取车辆的车牌号和OBU设备的设备号码或CPC卡的卡号;步骤2:将摄像头所读取的车牌号码发送到服务器,从服务器获取该车牌号码所对应的OBU设备的设备号码或CPC卡的卡号;步骤3:从摄像头所在的同一龙门架上的RSU设备在预设时间段内所读取的一个或多个设备号码或卡号中寻找,判断是否存在步骤2所获得的设备号码或卡号,若不存在,则发出告警信息。同时本案还提供了一种路网监测系统。
