摘　　要：针对地铁站出现异常大客流,为避免地铁通行费流失、单程票卡流失,加快乘客通行速度,开发了便携式人工检票机。人工检票机以PowerPC405为核心,外围模块包括无线网卡、非接触式IC卡读写装置、FLASH存储器件、语音提示等。软件架构由数据通信模块、票卡交易模块和人机界面模块组成。为了保证数据的安全和完整,就便携式人工检票机的身份认证、设备的登记与注销、数据的签名进行讨论,并给出相应的实现方法。实验结果表明:本文开发的便携式人工检票机交易时间小于250 ms,最大通过客流为30人/min左右,蓄电池供电时可连续工作8 h以上,本便携式人工检票机能实现快速检票功能,对环境无特殊要求,可作为闸机的有效补充手段。According to unusual great passenger flows in the subway station, portable examining Machine （PEM） was developed not only to avoid losing of toll fee and one - way ticket cards, but also to speed up the passenger transit. PEM uses PowerPC 405 as core, and its peripheral modules include wireless network card, contactless IC card reader, FLASH memory and so on. The software framework of PEM is made up of data communication, ticket processing and human - machine interface module. In order to guarantee the data security and integrity, PEM status authentication, the equipment registration and logout, and data signature were discussed, and the corresponding method of realization was given. The experimental results show that the ticket processing time of PEM is smaller than 250 ms, and the maximal passenger transit volume is about 30 persons per minute. PEM can work above 8 h continuously with power supplied by storage battery. PEM can speed up tickef examining and has no special requirements to working environment, so it can be used as effective supplementing means of AFC（Automatic Fare Collection） gates.
