摘要
在对RS485和TCP/IP通讯协议研究的基础上,介绍了一种基于射频识别技术的非接触式IC卡电子密码锁系统,并提出了整个系统的解决方案。系统采用分布式结构和集中统一管理相结合,由三个层次组成:管理中心服务器、用户楼栋PC、电子密码锁。重点阐述了以单片机STC89C58RD+芯片为核心、飞利浦公司的MFRC530为射频基站的电子密码锁的工作原理及硬件组成和软件设计。与传统的电子锁系统相比,具有显著的优越性。试验结果表明:系统运行稳定,实时性好,方案可行。
Based on the research of RS485 and TCP/IP Communication Protocol, the paper introduces an Electronic Lock System of Non-contact IC card and puts forwards the solution of the whole system. This system adopts distributed architecture and is combined with the centralized and unified management. It can be classified into three aspects： management center server, user building PC and Electronic Cipher Locks. The paper emphases on the general principle and the design of hardware and software of this kind of Electronic Cipher Lock system, which takes Micro-controller STC89C58RD＋ chip as core and Philips＇ MFRC530 for RF base station. Compared with the traditional Electronic Lock system, this system has significant advantages. The results prove the feasibility of the scheme and show that the system is stable and has a good real-time performance.
