摘要
针对目前流行非接触式智能IC卡小型化,低功耗的发展趋势,创新性地采用Atmel公司的Temic T5557非接触式IC卡及ARIC-A型嵌入式射频卡读写模块设计了一套智能门禁管理系统。系统通过对读写卡程序的优化设计,系统运行时,读卡器反复检测是否有射频卡信号,当有卡进入读卡能量范围时,读取卡内数据,通过RS-232接口与PC机组成通信系统。应用结果表明,系统长时间运行正常,稳定可靠,同时具有实时时钟及报警功能,系统全部采用串行接口,通用性强,功耗极低,具有很强的实用性与工程推广价值。
Because of the lower power cost and miniaturization of the smart IC card,the paper introduces a intelligent door-entry control system applying Atmel's Temic T5557 non-contact IC card and the ARIC-A type of embedded RF card reader module.Through the optimization design,the system detect signal repeatedly.When the card entered into the scope of RF energy,the data of the card will be read.Through RS-232 interface and PC constituting the communication network.Application results show that the system can run longtime normally,stably and reliably.The system use serial interface,real-time clock and alarm function with high universality.Due to the lower power loss,the technology and methods adopted in the system are practical and worthy of using abroad.
