Acoustic detector for installation inside box, method for notifying abnormal situation using the same, automatic control system for abnormal situation, computer readable medium, and computer program

Abstract

An acoustic detector is disclosed comprising: an acoustic sensor array for receiving an ultrasonic acoustic signal generated from a monitored object provided inside a box; a data processing unit for determining whether the monitored object is in an abnormal state by comparing the sound pressure level of the received ultrasonic acoustic signal with a threshold value and generating an alarm signal when the monitored object is determined to be in an abnormal state; a communication unit for transmitting the generated alarm signal to another device; and a storage unit for storing ultrasonic acoustic data corresponding to the ultrasonic acoustic signal. The acoustic detector may be installed inside the box to detect the ultrasonic acoustic signal generated from the monitored object.
