摘　　要：NFC（Near Field Communication,近场通信）技术由不同标准演进而来,其标准尚未完全统一,市面上大量存在遵循不同标准的NFC产品,它们并非完全兼容。越来越多智能手机支持NFC模拟交通卡业务,同时交通运输部正在全国范围内升级改造公交、地铁NFC读卡器,NFC协议兼容问题突出。国内目前尚无NFC协议测试设备,为解决此问题,基于Python开源NFC协议栈软件库nfcpy设计一个低成本NFC协议互操作测试平台。相比传统的采用真实NFC POS终端和非接触卡进行协议兼容性测试,本文方案有如下两个优势：（1）除模拟符合协议的NFC设备外,还可以灵活构造不同协议异常情形;（2）使用模拟的NFC设备取代真实设备,能够实现完全的无人值守自动测试;同时也省去搜集和采购不同型号NFC设备的工作。NFC technology is evolved from different standards,which are not yet unified.Therefore,a large number of NFC products on the market follow different standards and are not completely compatible. More and more smart phones support NFC based traffic card emulation,while China Transport Union is upgrading the bus and subway NFC card reader throughout the country,and the NFC protocol Interoperability problems are outstanding.At present,there is no Chinese NFC protocol testing equipment.To solve this problem,based on the Python open source NFC protocol stack software library nfcpy,a low cost NFC Interoperability test platform is designed.Compared with the traditional Interoperability test using real NFC POS terminals,the proposed approach has the following two advantages：（ 1） Besides the normal NFC scenarios,the proposed approach is capable to simulate different possible abnormal NFC protocol scenarios;（ 2） By using simulated NFC POS terminals,the proposed approach can realize automatic testing and reduce cost significantly from collecting and purchasing different types of NFC POS terminals.
