为了降低视频监控系统的成本,提高系统布防的简易性,使其具有较好的稳定性和实时性,利用QT设计了一款基于嵌入式视频服务器的监控系统。系统采用三星公司的S3C2440微处理器芯片为核心的ARM9开发板为硬件平台,在其上搭建LINUX系统的网络视频服务器,用QT为用户图形界面开发了客户端软件,并运用了多线程技术。实验结果表明,该系统很好的达到了预期目标,可以稳定实时地显示一路或多路视频监控图像,降低了采用模拟摄像头的很大一部分成本,布防简单。
In order to reduce the cost of the video surveillance system and improve the ease of deployment of the system so that it has good stability and real-time performance, a monitoring system based on embedded video server is designed by using QT. The system adopts ARM9 development board with Samsung S3C2440 microprocessor chip as the hardware platform, builds the LINUX system network video server on it, develops the client software with QT for the user graphical interface, and utilizes the multi-thread technology. The experimental results show that the system achieves the expected goal of being able to display one or more video surveillance images in a stable and real-time manner, reducing a large part of the cost of using analog cameras and simplifying deployment.
