针对传统视频监控系统存在的不足，采用具有更高处理速度、更小体积的ARM11作为核心处理器，结合现代流媒体技术和无线网络技术，对一种具有硬件实现简单、性能可靠稳定、携带方便的视频监控循环服务器进行了设计与研究。该服务器在软件设计上，采用嵌入式Linux系统下多线程编程方法，克服了通用服务器程序设计方法的缺点，较大提高了程序的运行效率。经过测试服务器性能稳定，可满足工业中某些特殊场合的实时监控要求，具有一定的实用性。% Aiming at the shortcomings of traditional video monitoring systems, a cyclic video monitoring server, which has characteristics of simple hardware realization, reliable and stable performance and easy to carry about, was designed and researched. It used the ARM11 core processor that has a smaller size and higher processing speed, and combined modern streaming media technology and wireless network technology. In software design, this server employed multi-threaded programming methods under the embedded Linux system, overcame the disadvantages of the programming methods used for general server program design methods and improved the operational efficiency of program greatly. The server was tested to prove its stable performance, possibility of applying to real-time monitoring in some special industrial occasions, and practicality.
