Description

Technical Field

[0001] The present invention belongs to the field of sound barriers, and specifically relates to a dynamic sound barrier system and a control method based on noise monitoring and regulation. Background Art

[0002] Road transportation is an indispensable part of promoting economic development. In order to strengthen economic construction in remote areas, roads are also built in mountainous areas, plateaus and other areas. This will inevitably pass through some animal habitats. Roads in such areas will have a greater impact on the animals living there, and animals crossing the road will also have a great impact on traffic. Therefore, sound barriers need to be set up on roads in animal habitats to avoid mutual interference between animals and vehicles; at the same time, they also reduce the noise of vehicles and reduce the impact of noise on animals. However, conventional sound barriers will restrict the activities and migration of animals, which is not conducive to the survival and reproduction of animals. Some existing patents propose setting up wildlife passages on sound barriers, but the noise from vehicles can scare animals, making them afraid to enter the wildlife passages, making the wildlife passages ineffective. Moreover, if animals do not use the wildlife passages and mistakenly enter the road from the entrance or other locations of the sound barrier, the existing sound barriers do not have corresponding measures to avoid traffic accidents.

[0003] Therefore, it is of great practical significance to develop a sound barrier system that can coordinate traffic and animal survival and effectively reduce the impact of vehicle traffic on animals. Summary of the Invention

[0004] The purpose of the present invention is to provide a dynamic sound barrier system and control method based on noise monitoring and regulation, which can effectively adjust the shielding effect of noise based on noise monitoring, reduce the impact of noise on animals, and thus enable wildlife passages to play their due role, reduce the impact of traffic on the living environment of animals, and at the same time, through acoustic driving and lure, disperse animals that are about to enter the sound barrier or have already entered the sound barrier system, avoid causing traffic accidents, and achieve the unity of economic development and ecological friendliness.

[0034] The closed sound barrier 2 is provided with a sawtooth structure 21 at the top to scatter sound waves, reduce the coherent superposition of internal sound waves, and reduce reverberation sound.

[0035] The open sound barrier 1 is provided with a wind speed sensor for monitoring the wind speed to avoid damage to the shielding component 11 of the sound barrier caused by strong wind.

When the vehicle is monitored to enter, the noise signal is collected and the noise change trend is predicted; when the animals are monitored to appear, the acoustic driving system is triggered to drive; The signal collected here is fed back to the control system, which can use a basic algorithm. The analog-to-digital conversion algorithm (ADC algorithm) converts the continuous analog sound signal captured by the noise sensor into a discrete digital signal for processing by the control system. At the same time, a FIR or IIR filter is also needed to filter the interference frequency band to accurately locate the vehicle noise. The fast Fourier transform (FFT) algorithm is used to convert the time domain signal to the frequency domain signal to obtain the frequency spectrum.
