The previous landslide image acquisition system adopts a continuous image acquisition and transmission method, which has high consumption and produces many redundant data. Therefore, a new landslide image acquisition system is developed in this paper. The system adopts seismic geophone to gain landslide motion data, and then the dual limit comparator filters out the landslide motion data and forms a trigger signal to wake up the system. In the end, after being awakened, the embedded micro-controller collects and transmits the image. With the intermittent image acquisition and transmission method, the equipment keeps in a low-power consumption for a long time when the landslide movement is not severe. The equipment will be awakened only when the landslide movement is violent. It turns out that compared with the continuous acquisition method, the power consumption of the system can be reduced by about 66%, and the data amount can be reduced by about 60KB when the system is triggered only once in a minute.
