摘要:
分析了城市轨道交通自动售检票系统脱机数据认证模式及联机预授权模式的优缺点,提出将联机预授权模式作为主模式,用于网络实时传输条件允许的情况,并将现有的脱机数据认证模式作为网络不佳时的降级备用模式。这一解决方案不仅有效解决了ODA模式下扣款不成功和单边扣费频发的问题,还提高了乘客持银联IC卡过闸的便利性,提高了闸机的通行效率。
Abstracts:
The merits and shortcomings of urban rail transit AFC (automated fare collection) system ODA (offline data authentication) mode and online preauthorization mode are analyzed. It is proposed to adopt online preauthorization mode as the main one, for the situation where network real-time transmission conditions allow, and the current ODA is downgraded as a backup mode in the case of network failure. It effectively solves the problems of unsuccessful deductions and unilateral deductions under old ODA mode, improving gate-passing convenience for UnionPay IC card users and gate-passing efficiency overall.
