KR-20260063818-A - ICT acoustic safe alarm system

Abstract

The present invention relates to a directional smart ICT acoustic safety alarm system for preventing disasters in a complex space, comprising: a speaker array (110) formed by arranging a plurality of speakers (111) to emit a directional acoustic beam; a speaker control unit (120) that controls the phase and amplitude of acoustic signals transmitted to the plurality of speakers (111) and controls the speaker array (110) to irradiate a directional acoustic beam in that direction based on location information of an abnormal zone transmitted from a situation monitoring unit; and a first communication unit (130) that communicates with a situation monitoring unit or an external device; and a situation monitoring unit (200, 300) that monitors the situation of a monitoring area and transmits (transmits) location information of an abnormal zone (Aera_i) to the acoustic beam emission unit (100) when an emergency (abnormal) situation occurs.

Description

Directional Smart ICT Acoustic Safety Alarm System for Disaster Prevention in Complex Spaces { ICT acoustic safe alarm system } The present invention relates to a directional smart ICT acoustic safety alarm system for preventing disasters in complex spaces. As prior art, the title of the invention filed under KR No. 10-2140375 on September 4, 2018, describes a warning sound output system using directional speakers comprising: a plurality of speakers that generate and output a super-directional signal by synthesizing an audible frequency band signal and an ultrasonic frequency band signal to produce a warning sound; and a plurality of LiDAR sensors that measure the position and speed of a vehicle to detect overspeeding, congestion, and sudden braking of the vehicle. A warning sound output system using a directional speaker is disclosed, comprising: a control unit that controls the plurality of speakers and lidar sensors; wherein the plurality of speakers and lidar sensors adjacent to each other are configured as a pair and are installed in a line at a certain distance apart along the direction of vehicle travel inside a tunnel and operated in conjunction; and when the speed of a vehicle passing through point N (N is a positive integer) is measured by the lidar sensor to exceed the safe speed, an overspeed warning sound is output from the speaker at point N+1; when the speed of one or more vehicles passing through points N-1 (N is a positive integer) to N+1 is measured to be the same by the lidar sensor, a traffic congestion warning sound is output from the speaker at point N-4; and when the difference in speed between one or more vehicles passing through points N (N is a positive integer) and N+1 is measured to be 50 km/h or more by the lidar sensor, an emergency stop warning sound is output from the speakers at points N-4 to N-1.
