In recent years, extreme climates have occurred frequently around the world, and landslides and mudslides in mountainous areas caused by heavy rainfall, earthquakes and other factors have increased significantly, seriously threatening the safety of people's lives and property. Traditional manual inspection methods have problems such as blind areas in monitoring, poor timeliness, and lagging early warning. By deploying the Internet of Things monitoring system, real-time perception, intelligent analysis, and accurate early warning of geological risks can be achieved, and prime time for emergency decision-making can be gained.
