At present, the monitoring of debris flow in China is mainly oriented to the middle and low altitude areas, and the geological disaster monitoring and warning network mainly covers the risk points of geological disasters in the middle and low altitude areas. For the high cold and high altitude areas, the monitoring is blind at present, but once the eruption of debris flow in the high cold mountain area, it will have a huge impact on the downstream debris flow. Based on 4G+LoRa multi-network fusion communication technology, this paper studies how to realize long-term stable monitoring and early warning of debris flow gully in the alpine mountains by means of the cooperative working mode of rain gauge and camera and by means of self-adaptation to the weather.
