摘要
为满足在恶劣条件下对基建现场进行视频监控的需求,采用了5.8 GHz频段高速无线以太网桥对无线局域网与有线局域网进行系统组网,通过点对点传输技术及MPEG-4视频图像压缩技术实现远端视频监控功能,并利用有线对等加密算法对视频信号进行128 b加密,保证了视频信号传输的流畅度、清晰度及安全性,并对该系统的硬件实现进行了详细说明。经过实际测试,该系统具备移动灵活、易于组建、高速率、高稳定性等特点。
To meet the video surveillance demand of capital scene in bad condition, a method of connecting wired LAN to wireless LAN by using wireless bridge worked in 5.8GHz is introduced, the far end video monitor is realized by using the peer-to-peer transmission technology and video compression code standard MPEG-4, the wired equivalent privacy algorithm is used to encrypt video signal by 128 bit to ensure the transmission of video data with fluency, high definition and safety. At last, the hardware implementation of the system is discussed. The results of simulation and testing indicate that the system has advantages such as flexible movement, high speed, high stability and so on.
