摘　　要：地质灾害监测预警作为地质灾害防治的重要组成部分,已经完成了从人工监测到自动化监测,从2G网络到4G网络再到低功耗物联网的提升,但主干通信网络的覆盖范围、地质灾害周围地形和其他干扰因素,尤其是突发性灾害严重影响了地质灾害监测预警网络的稳定性和实时性。本文针对现有的影响因素,提出了基于多网通信融合和边缘计算的现场自组网技术方案。通过构建支持多种通信方式和数据采集协议的设备,并利用边缘计算技术实现数据的实时处理与分析,以提高地质灾害监测预警系统的效率和准确性。本文在重庆市巫山县两坪乡朝元村9组三合铺滑坡建立了示范应用点,设计并搭建了地质灾害监测预警现场自组网系统,通过模拟突发事件检验通信网络中断后的监测数据采集、传输和预警。测试结果显示,本系统可在无外部通信网络情况下实现基于边缘计算设备的自主监测预警。As an important component of geological disaster prevention and control,the ways of geological disaster monitoring and early warning have been improved from manual monitoring to automatic monitoring and from 2G network to 4G network and then to low-power Internet of Things.However,the coverage range of main communication networks and the terrain around geological disasters,as well as other interference factors,especially sudden disasters,affect the stability and real-time performance of geological disaster monitoring and early warning networks.This paper proposes a field self-organizing network technology scheme based on multi-network integration and edge computing in view of existing influencing factors.By building equipment that supports various communication methods and data collection protocols,and utilizing edge computing technology to realize real-time data processing and analysis,the efficiency and accuracy of geological disaster monitoring and early warning systems can be improved.A demonst ration application point has been set up and a field self-organizing network system for geological disaster monitoring and early warning has been designed and built in Santapou landslide,Wushan County,Chongqing City.The communication network interruption during emergencies has been simulated to test data acquisition,transmission,and early warning.The test results show that this system can achieve autonomous monitoring and early wa rning based on edge computing devices without external communication networks.
