ABNORMALITY DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an abnormality detection device capable of early detecting the leakage of gas or the generation of combustion flame by the combustion of combustive gas with high reliability. SOLUTION: This abnormality detection device has: an acoustic sensor 10 processing an acoustic signal in a monitoring target facility to detect an abnormality in the monitoring target facility; an image sensor 12 processing an imaged image to detect the abnormality in the monitoring target facility; and a monitoring part 16 compositely deciding the abnormality in the monitoring target facility on the basis of the detection result of the abnormality by the image sensor 12 and the detection result of the abnormality by the acoustic sensor 10.
