本文从电子不停车收费系统(ETC)应用现状和发展趋势出发,针对当前影响ETC应用,制约ETC进一步发展的邻道干扰问题进行了深入研究,对引入邻道干扰的各种因素进行了分析,指出邻道干扰的根本原因,阐明邻道干扰现象存在的客观性。并基于以上分析,从DSRC区域控制、引入车辆检测装置、车牌识别和附加车道隔离装置等几个方面提出了解决邻道干扰问题的关键环节和技术措施,并从理论、技术和工程实施等方面进行分析论证。
In this paper, based on the status quo and development trend of electronic toll collection system (ETC), the paper studies the current ETC applications and the adjacent channel interferences that restrict the further development of ETC, and analyzes various factors of introducing adjacent channel interference. Point out the root cause of the adjacent channel interference and clarify the objectivity of the adjacent channel interference phenomenon. Based on the above analysis, the key links and technical measures to solve the adjacent channel interference are put forward from the aspects of DSRC area control, the introduction of vehicle detection devices, license plate recognition and additional lane isolation devices. From the aspects of theory, technology and project implementation, Analyze and prove.
