Abstract

The invention discloses an urban noise pollution centralized monitoring system comprising a plurality of acquisition units and a receiving unit; the acquisition units each comprises a radio module, afilter, an A / D converter and a wireless communication module; the receiving unit comprises a master server, a central control processor and a display; the master server is used for receiving signals sent by the wireless communication modules in all the acquisition units and transmitting the signals to the central control processor; the central control processor is used for converting the receivedsignals into decibel values and judging whether the decibel values exceed a critical threshold value or not; and the display is connected with the central control processor and is used for displayingthe positions of all the signals exceeding the critical threshold value and the decibel values on a map. According to the urban noise pollution centralized monitoring system in the invention, the problem that in the prior art, no good monitoring means is for the urban noise pollution is solved, and the purposes of improving monitoring of the urban noise and enhancing the evidence obtaining strength are achieved.

Description

technical field [0001] The invention relates to the field of urban noise, in particular to a centralized monitoring system for urban noise pollution. Background technique [0002] With the continuous development of cities, noise pollution has gradually become a problem that cannot be ignored in people's market life, seriously affecting people's normal daily life, especially the noise of road vehicles, construction noise, and entertainment facility noise during rest periods. , these noise pollution will seriously interfere with people's daily life. However, in the existing technology, there is no complete and efficient monitoring method for noise pollution in each city, and they all rely on reports or complaints from disturbed residents, resulting in low processing efficiency, slow response time, and difficulty in obtaining evidence in the first place. Therefore, there is no better monitoring means for urban noise pollution in the prior art. Contents of the invention [0...
