摘　　要：利用ARM和QT开发了一款基于WiFi网络的无线视频监控系统.系统由远程视频采集端、WiFi网络和监控中心三部分构成.远程视频采集端采用PXA270 ARM10微处理器为核心的硬件平台,并在其上建立Linux操作系统,完成视频的采集、H.264编码压缩和传送.监控中心使用QT利用多线程技术开发了客户应用软件,实现监控视频的解码和显示.WiFi网络实瑞视频采集端和监控中心间的视频传输.使用效果表明,该系统能稳定实时地显示一路或多路视频监控图像,很好地达到了设计的要求,在各领域具有广泛的应用前景.A wireless video monitoring system was developed with ARM and QT based on WiFi network. The system was composed of the remote embedded video acquisition terminal, WiFi network and the monitoring center. In this system, the hardware platform with PXA270 ARM microprocessor chip as its core is used to capture video and the Linux system is built up on it. The client software is developed by QT and the multi-thread technology as well in order to display the video from acquisition terminal by WiFi network. The experiment results showed that the real-time display of one-way or multi-way video monitoring image could be achieved. The system could satisfy the requirements of design and would be widely used in various fields.
