城市轨道交通售检票系统系列票卡的兼容

Compatibility of Series Ticket Cards in Urban Rail Transit AFC System

为避免社会资源浪费,苏州轨道交通售检票系统在设计和网络化建设中应用兼容了1998年IC卡规范的苏州通卡和2005年IC卡规范的苏州市民卡,在建设过程中采取减少票卡处理时间、复用票卡数据位、简化数据记录制式、制定统一处理流程、调整天线射频参数等技术,逐步解决兼容和区分新老规范票卡、统一读写器的产品、统一票卡处理流程、实现线网内各票卡互联互通等问题,取得了较好的经济效益和社会效益。

In order to avoid the waste of social resources, Suzhou rail transit AFC system is designed to be compatible with Suzhou City Card（IC Card specification： PBOC1.0） and Suzhou Citizen Card（ IC Card specification： PBOC2.0）. Some techniques such as re- ducing card processing time, multiplexing ticket card data bits, simplifying data record standard, adjusting RF parameters of antenna, etc, are applied in the process of integrating these two cards. Some difficult problems such as distinguishing cards of PBOC1.0 standard from those of PBOC2.0 standard, integrating read/write device product and processing flow, interconnecting all tickets in network were solved. The work achieved good economic and social benefits.
