智能保密柜嵌入式控制系统的设计与实现

Design and Implementation of Intelligent Encrypting Equipment Based on Embedded Control System

为了提高保密柜管理的保密性和自动管理物品的能力,基于工业级AT91SAM9260处理器设计了一个智能保密柜嵌入式控制系统。该系统具有指纹识别开启柜门、摄像记录、RFID读写器采集柜内物品ID以及保密柜所有操作的文件记录等功能。对开源的μC/OS-Ⅱ与Linux操作系统进行了分析比较,选择Linux作为嵌入式操作系统,在进程调度、文件系统管理等方面提供了很好的支持。应用结果表明,该系统具有较好的实时处理能力,可以满足用户的应用需求。

To enhance the confidentiality of encrypting equipment and improve management ability to the items,an intelligent encrypting equipment based on embedded control systems,which uses an AT91SAM9260 processor,is designed.The encrypting equipment provides functions of encrypting and management,such as fingerprint identification to open door,camera record,ID of item in equipment（collected by RFID reader） and operation record of all documentations in the encrypting equipment.Linux operating system is chosen as the embedded operating system based on analysis and is compared with μC/OS-II.A good support is provided for the process scheduling and file system management.Application result shows that the intelligent encrypting equipment can meet the requirements of users.
