摘要
在ETC车道系统中,相邻两个ETC车道之间的OBU与RSU相互影响,RSU与非本车道上的OBU进行通讯并完成交易,引起邻道干扰;工程实施、设备等原因引起跟车干扰,造成ETC收费失败。针对存在的问题,分析工程安装、设备原因,提出切实可行的解决方案,保证ETC车道功能的正确性、完整性,是交通运输行业节能减排绿色发展成果之一。
In an ETC system instead of sending the signal to the OBU in its own lane the RSU of one electronic-toll-collection lane may interact with the OBU in a adjacent lane causing a phenomenon of Adjacent-channel Interference; meanwhile errors in installing ETC facilities equipments etc. would bring about the problem of Successive-car Interference. Each of the two problems mentioned above would lead to a failure to collect tolls electronically. By analyzing the installment of a problematic ETC system and its facilities thoroughly this paper provides pragmatic solutions to the existing interference and thus ensure the smooth operation of the system.
