摘要
基于QCA9558芯片、嵌入式系统服务、无线组网技术、QT技术,设计了无线视频传输系统,该系统由视频采集节点、Wi-Fi无线多跳网络、上位机客户端软件组成。在MIPS平台上移植嵌入式OpenWrt操作系统;组建Wi-Fi无线多跳网络,完成网关节点和路由节点的设置,制定了数据通信协议;使用QT技术设计PC客户端程序。通过测试,系统性能良好,满足视频传输的需求,系统可以用于实验教学及科研研究。
Based on QCA9558 chip, embedded system service, wireless networking technology and QT technology, a wireless video transmission system is designed. This system consists of the video capture node, Wi-Fi wireless multi-hop network and client software of upper computer. The embedded OpenWrt operating system is transplanted on the MIPS platform, the Wi-Fi wireless multi-hop network is established, the gateway node and routing node are set up, and data communication protocol is formulated. QT technology is used to design the PC client program. Through testing, the system has good performance and meets the needs of video transmission, which can be used in experimental teaching and scientific research.
