摘要 电子密码锁系统在很多实时系统中得到了广泛的应用，随着ARM技术和网络技术的发展，本文提出了一个基于ARMμC/OS-II的电子密码锁技术的研究，该系统以嵌入式实时操作系统μC/OS-II为软件平台，在ADT环境下进行系统软件的开发。该系统充分利用了ARM微处理器高性能、低功耗、低成本的优势，μC/OS-II和可移植性好、开发成本低的优点，为电子密码锁系统的研发提供了一个可行的解决方案。 μC/OS-II的系统的移植，并通过S3C2410实现了串行接口的通信，键盘的输入扫描和CF卡的数据读写等主要模块的功能。完成一个具有键盘输入和卡片读取，并与服务器进行数据通信的电子密码锁系统的识别卡端。 关键词：电子密码锁； 嵌入式系统； ARM ； μC/OS-II ABSTRACT The electronic password locking system has been applied widely in a lot of real-time systems. With swift development of ARM and network technology, a new technology of electronic password locking system based on ARM and μC/OS-II was brought forward and researched in this paper. The system adopted SAMSUMG 32 bit high-powered ARM92410 core and utilizing embedded real time operating system μC/OS-II as software platform, at the same time ,this software system has been developed in ADT (ARM Development Tools) environment .In this system，some predominance of ARM MPU (microprocessor) were adequately used，such as the high-powered, low power waste, low cost，which bring into play its excellence in good transplantation and low development-cost, therefore, the new study in this paper affords a feasible scheme for the research of electronic password locking technique system. In this foundation, this article has mainly carried on the μC/OS-II system transplant, and has realized the serial interface correspondence, keyboard input scanning and CF card data read-write and so on main module function through S3C2410. Completes the electronic password locking system recognition card end with to have the keyboard entry and the card reads takes, and carries on the data communication with the server.
