Conceptual Design of a Simple Earthflow Detector for Resident Disaster Prevention

Abstract

Abstract The earthflow disaster is massive in scale and fast, causing damage to mountain towns and traffic. Field observation instruments developed for the earthflow warning, such as wire rope stress detection, ground sound sensing, and detection of relative motion. Evacuate residents of dangerous areas through broadcast systems and disaster prevention personnel. Residents have no direct access to relevant information, and information lags and incompleteness reduces trust. The design of the simple detector detects the movement of the soil layer with a tilted, areal breakpoint measurement. Cooperate with global data APP to improve the performance of early warning. The inexpensive sensors included positioners, inclinometers, and soil moisture detectors. Combine these data provided a suitable local response and become a medium for self-help and mutual help. The unmanned aerial vehicle take pictures along the preset specific path when triggered providing the first-hand disaster data.
