微波定向区域覆盖在应急救援通信保障中的应用探讨

Discussion on the Application of Microwave Directional Area Coverage in Emergency Rescue Communication Support

在大型复杂灾害事故救援处置现场,通常会有多部门协同配合开展作业,因而指挥通信业务繁忙。消防救援队伍在使用公共移动通信网上传各种信息特别是现场多路视频信息时可能会面临带宽不足、信道争夺的情况,甚至会面对现场断网、断电、断路的情况。微波通信具有带宽大、信道相对独立的优势。该文作者结合自身工作经验,对使用微波数字通信对灾害事故现场进行快速覆盖、实现通信网络延伸,保证消防救援队伍指挥通信连续、通畅、可靠的可行性进行了测试和分析。

In the rescue and disposal site of large-scale and complex disaster accidents,multiple departments usually cooperate to carry out operations,command communication business is busy,and fire rescue teams may face insufficient bandwidth and channel competition when using public mobile communication networks to transmit various information,especially multi-channel video information on site.They may even face on-site network outages,power outages,and circuit breakers.Microwave communication has the advantages of large bandwidth and relatively independent channels.The author of this article,based on their own work experience,tested and analyzed the feasibility of using microwave digital communication to quickly cover disaster accident sites,achieve communication network extension,and ensure continuous,smooth,and reliable command and communication of fire rescue teams.
