介绍了一种公路自动收费系统的设计, 重点叙述了基于光纤传感技术的车型自动识别子系统, 它配以非接触性IC 卡, 可实现智能化不停车公路自动收费。 关键词 光纤 传感器 自动收费系统 车型识别 IC 卡 Abstract: In the paper the autho rs p resent a system w h ich is designed to ident ify veh iclemodel automat ically based on the op t ic fibre senso r techno logy. W ith nono sculant IC card, it can realize the intellectualized auto to ll system w ithout veh icle’s stopp ing. W ith such advantages as h igh2 efficiency, low 2co st and h igh2p recision, the system has a brigh t future. Keywords: op t ic fibre; senso r; auto to ll system; ident ify veh icle model; IC card
