An Active Noise Control System Integrated in Road Lighting System

Abstract

The invention discloses an active noise control system integrated in a road lighting system, which belongs to the field of road noise reduction. The system includes at least two noise active control street lamps; the i-th noise active control street lamp is connected to the i+1 noise active control street lamp; the i-th noise active control street lamp collects the i-th vibration and noise data, and receives the i-1th vibration Noise data, the i-1th control output, the noise control evaluation result is obtained according to the vibration noise data and the control output, the noise control algorithm is evaluated and adjusted according to the noise control evaluation result, and the i-th Control the output, control the speaker to output sound waves, send the i-th vibration and noise data and the i-th control output; solve the problem that the existing road lighting system cannot actively eliminate noise, and the noise control effect of road vehicles is not good; it has fully considered resources of the road lighting system and improve the effect of active noise control.

Description

technical field [0001] Embodiments of the present invention relate to the field of road noise reduction, in particular to an active noise control system integrated in a road lighting system. Background technique [0002] Vehicles will emit different levels of noise when driving on the road. Vehicle noise will not only cause disturbance to drivers, passengers and pedestrians, but also cause troubles to the life and work of people who live and work on both sides of the road. The living comfort of the residents will reduce the work efficiency of the staff, and even cause harm to the human spirit in serious cases. In addition, in some suburbs, although there are few people living and working, poultry and livestock may be raised around the roads, and the noise of vehicles will also adversely affect the normal growth and reproduction of poultry and livestock. Contents of the invention [0003] In order to solve the problems in the prior art, an embodiment of the present inventi...

Problems solved by technology

[0002] Vehicles will emit different levels of noise when driving on the road. Vehicle noise will not only cause disturbance to drivers, passengers and pedestrians, but also cause troubles to the life and work of people who live and work on both sides of the road. The living comfort of the residents will reduce the work efficiency of the staff, and even cause harm to the human spirit in serious cases.

In addition, in some suburbs, although there are few people living and working, poultry and livestock may be raised around the roads, and the noise of vehicles will also adversely affect the normal growth and reproduction of poultry and livestock.
