基于ARM9与Linux的门禁监控系统

提出了一种可配置、功耗低的门禁监控系统软件设计方案，该方案基于ARM9与Linux相结合的软硬件平台，同时结合CGI技术实现。系统由前端摄像头，读卡器，门禁控制器以及客户端组成。人员出入的时候，经刷卡后将卡内信息传输到门禁控制器，门禁控制器检测卡权限是否合法以决定是否开门，同时控制前端摄像头摄录图片传输到门禁控制器存储并进行日志记录。用户可以在客户端通过Internet访问门禁控制器，进行人员信息的录入和日志访问等。与传统方法相比，该方案设计在易操作和低成本上具有明显优势。

Abstract:

 Proposed a system software design of the access control that is configu-rable，low power consumption，which is using a platform combine with hardware and software with ARM9 and Linux，while with CGI technolog.This surveillance system is composed by the front camera，card reader，access controller and client components，when officer out，the credit card information will be transmitted to the card access controller，and access controller detects whether the card is the legitimate auth-ority to decide whether to open the door，through transmitting the front-end video camera images to the access control and logging.User clients can access Access Controller by Internet，entry personnel information and log access and so on.Compared with traditional methods，the program design has obvious advantages in easy operati-on and low cost.
