摘要： The inventive concept relates to a device that detects a leak of a liquid leaked from a sinkhole, water pipe or oil pipeline under the ground. In the detection device of the inventive concept, a plurality of reception devices disposed on the surface of the earth simultaneously receive an ultrasonic signal transmitted from a transmission device under the ground and a radio frequency (RF) signal synchronized with the ultrasonic signal. Also, by measuring an arrival time of the ultrasonic signal by using the wireless signal received by each reception device as a triggering signal, a leak range of a liquid leaked from a sinkhole, water pipe or oil pipeline on a signal path between the transmission device and the reception device is detected.
