摘要
在对射频识别技术研究的基础上,介绍了一种基于RS485和TCP/IP通讯协议的联机型非接触式IC卡门禁控制系统,提出了整个系统的解决方案。系统采用分布式结构和集中控制方案,由三个层次组成:管理服务器、楼层PC、门禁读卡器。与传统的门禁系统相比,具有显著的优越性。重点阐述了以MCS-51单片机为核心、飞利浦公司的MFRC530为射频基站的门禁读卡器工作原理及硬件和软件设计。实际应用结果表明,系统运行稳定,实时性好,方案可行。
Based on the study of the RFID technology, this paper introduces a kind of on-line entrance guard system of contact-less IC card based on the RS485 and TCP/IP protocol, and proposes the solution of the whole system. The system adopts distributed structure and centralized control strategy, which consists three levels： management server, PC on the every floor, entrance guard reader device. Compared with the traditional products, this system has more advantages. The paper expounds the principle, hardware and software design of the entrance guard reader device which take single-chip of MCS-51 as core and Philips＇s MFRC530 as the RF base station. Practice shows that the system works stable, real-time performance is good and the scheme is feasible .
