AI Technical Summary

Technical Problem

Existing road noise monitoring devices cannot effectively monitor noise from different directions, especially they cannot trace the source of continuous, long-term noise, resulting in low monitoring efficiency.

Method used

Design a road noise monitoring device based on intelligent transportation. It adopts two sets of sound collection covers, one above the other, each with a separate orientation. Through the cooperation of the rotating shaft, guide sleeve, synchronous pulley and linkage belt, the sound collection covers can be adjusted in multiple directions and heights. The device integrates a noise monitor with the municipal intelligent transportation system for comprehensive analysis and noise source tracing.

Benefits of technology

It improves the efficiency and range of noise monitoring, effectively tracks noise from different directions and heights, enhances the noise collection area, and achieves efficient noise monitoring and source tracing capabilities.

Abstract

The application discloses a kind of road noise monitoring devices based on intelligent traffic, it is related to intelligent traffic system technical field, including stand, two groups of support seat are set on stand, multiple sound collectors are all set on support seat, and multiple sound collectors are respectively towards multiple directions, sound collector is rotatably connected with support seat by pivot, traffic noise monitor is also installed on stand, noise monitoring system is arranged inside traffic noise monitor, and is accessed in municipal intelligent traffic control system, noise sensor is installed in the inside of sound collector.The application is by setting two groups of sound collectors, and each sound collector has separate orientation, so in actual monitoring, multiple sound collectors can be used to different height and different direction noise volume, so as to facilitate system to carry out comprehensive processing and analysis, and carry out noise tracing, and the rotation of each pivot support makes that the orientation of sound collector can be adjusted, further improve the tracking ability of device to noise.
