摘　　要：应急无线通信是应急管理信息化建设任务中至关重要的一部分,在灾害事故抢险救援过程中发挥着通信兜底的关键作用。川西高山峡谷地带地形复杂,自然灾害多发频发,应急无线通信网络需要具备更强的抗毁性和覆盖率。本文以四川省雅安市应急无线通信系统建设为例,研究采用“基站信号覆盖+无线链路组网”的方法理论,构建宽窄带融合的应急无线通信组网架构。研究提出“骨干网高点传输+次级网低点互联”相结合的多层级、多环路无线传输网络建设方法,提升网络抗毁性、容灾性和稳定性,为灾害事故抢险救援现场情报获取、音视频传输、指挥调度等业务提供高效可靠的通信保障能力,最大程度降低灾害事故损失。Emergency wireless communication is a crucial part of emergency management informationization construction tasks,and plays a fallback key role in communication during disaster and accident rescue processes.The terrain in the high mountain and canyon areas of western Sichuan is complex,and natural disasters occur frequently.Emergency wireless communication networks need to have stronger resilience and coverage.This paper takes the construction of emergency wireless communication system in Ya’an,Sichuan as an example,and studies the theoretical method of“base station signal coverage+wireless link networking”to construct an emergency wireless communication network architecture that integrating broadband and narrowband.The research proposes a multi-level,multi loop wireless transmission network construction method that combines“high point transmission of backbone network+low point interconnection of secondary network”to enhance network resilience,disaster recovery,and stability.It provides efficient and reliable communication support capabilities for intelligence acquisition,audio and video transmission,command and dispatch in disaster and accident rescue scene,and minimizes disaster and accident losses to the greatest extent possible.
