Document Type and Number:
Japanese Patent JP7051039
Kind Code:
B2
Abstract:
To provide a landslide disaster evacuation notification system capable of reliably detecting the amount of fluctuation of the ground and reliably relaying the detected amount of fluctuation to an external device, and having a low operation cost.SOLUTION: A landslide disaster evacuation notification system comprises: a plurality of GPS child devices 12 which are installed in a dangerous area H where there is a possibility that a landslide disaster may occur due to a ground collapse, measure three-dimensional position coordinates of positions where the child devices are installed by communicating with GPS satellites, calculate the amount of fluctuations when the measured three-dimensional position coordinates fluctuate, and are capable of transmitting the amount of fluctuations to a GPS mother unit 11; the GPS mother unit 11 capable of transmitting and receiving data with an autonomous UAV 13, while receiving the fluctuation amount from the GPS child units 12; the autonomous UAV 13 flying on a predetermined route, receiving data from the GPS mother unit 11, and enabling data relay to a data center 14; and the data center 14 for predicting a landslide disaster on the basis of the data received from the autonomous UAV 13.SELECTED DRAWING: Figure 1
