摘　　要：为适应智能管道的快速发展,加强管道沿线的风险防控,保证视频监控在油气管道河流穿跨越区域的传输质量,提出了一种基于点对多点微波技术的视频回传方案。该方案通过设置一个发射点和多个接收点,将视频监控数据在接收点与发射点之间通过无线微波技术进行传输,根据微波链路备余量来确定合理的传输距离,从而确定发射端和接收端的安装位置。该方案在接收点与发射点之间采用微波传输,传输带宽高达250 Mbps,克服了光缆在河流穿跨越区域施工困难的问题,降低了30%光缆敷设的施工成本,解决了多台智能高清监控站点传输带宽受限的问题,具有超大传输带宽、较强抗干扰能力、部署方便和后期运维便捷等优良特性,为视频数据流提供了高可靠性、高稳定性的传输方案。In order to adapt to the rapid development of intelligent pipelines,strengthen risk preven-tion and control,and ensure the transmission quality of video surveillance in the river crossing area of oil and gas pipelines,a video transmission scheme based on point-to-multipoint microwave technolo-gy is proposed.This scheme sets up one transmitting point and multiple receiving points,and transmits the video data between the receiving points and the transmitting point through wireless microwave.The reasonable transmission distance is determined based on the microwave link reserve,thereby the installa-tion positions of the transmitting and receiving ends are determined.The scheme uses microwave trans-mission between the receiving points and the transmitting point,the transmission bandwidth is up to 250 Mbps.Meanwhile,this scheme overcomes the difficulty in the construction of the optical cable in the river crossing area,saves the construction cost of optical cable laying by 30%,and solves the prob-lem of limited transmission bandwidth of multiple intelligent HD surveillance sites.This scheme not only has excellent features such as ultra-large transmission bandwidth,strong anti-interference ability,con-venient deployment,and convenient later operation and maintenance,but also provides a highly reli-able and stable transmission scheme for video data streams.
