Research on geological disaster monitoring and early warning based on multi-network integration and edge computing
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 demonstration 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 warning based on edge computing devices without external communication networks.
