AI Technical Summary

Technical Problem

Existing CCTV camera-based enforcement systems are ineffective in identifying vehicles or motorcycles that cause excessive noise due to limitations in noise detection, especially under adverse weather conditions, leading to inaccurate identification of noise sources and inability to impose fines.

Method used

A monitoring device equipped with a microphone array and a noise control system that utilizes beamforming technology to distinguish vehicle noise from ambient noise, coupled with a weather observation unit to enhance accuracy, and a central server for license plate identification and fine imposition.

Benefits of technology

Accurately identifies vehicles generating excessive noise and imposes fines even under adverse weather conditions, enhancing noise detection precision and enabling effective enforcement.

Abstract

Disclosed is a monitoring device. More specifically, the present invention relates to a monitoring device including a microphone array for detecting, in consideration of surrounding situations, sources of noise exceeding a threshold that may occur on outdoor roads, factories, and the like, and a noise control system using same. According to an embodiment of the present invention, a conventional CCTV camera, which is installed on a road to monitor vehicles in motion, is provided with a weather observation means and an outdoor noise measurement means, and there is an effect of detecting, by means of same, a sound source that generates noise greater than or equal to a threshold by determining surrounding conditions such as weather.
