Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0038] Such as figure 1 Shown is the method flow chart of the present invention, a kind of urban noise map drawing method based on mobile perception, comprises the following steps:

[0039] Step 1: Select a residential area in Guangzhou as the experimental area. The experimental area is about 300m×300m in size. The experimental area is gridded and divided into 100 grids of equal size. These 100 grids are complete covered the experimental area. In order to ensure the drawing accuracy of the urban noise map, under normal circumstances, the area covered by each grid does not exceed 900 square meters.

[0040] Step 2, the user collects noise data through the smartphone.

[0041] In the case of m...

Abstract

The invention discloses a noise map drawing method based on mobile perception in the technical field of noise monitoring, and aims to solve the problem that noise data of each corner are difficult tomonitor due to fixed-point layout of noise monitoring stations in the prior art. And when the scattered sparse noise is rendered by using an interpolation method, the technical problem that the influence of the space environment on noise propagation is not considered is solved. The method comprises the following steps of collecting and obtaining noise data in a target monitoring area through mobile noise measurement equipment, the noise data comprise noise value data and longitude and latitude corresponding to the noise value data, and the mobile noise measurement equipment comprises a smart phone; and rendering the noise data by using an inverse distance weighted interpolation method to obtain a noise map of the target monitoring area.

Description

technical field [0001] The invention relates to a noise map drawing method based on mobile perception, and belongs to the technical field of noise monitoring. Background technique [0002] With the continuous development of urban economy, noise pollution is becoming more and more serious, and people are paying more and more attention to it. The noise map refers to the noise value distribution map that is finally drawn through the simulation of the acoustic simulation software and the correction of the actual measurement data of the noise. The urban noise map is a data map reflecting the urban noise level generated after comprehensive analysis and calculation of the sound source data and traffic information on the basis of quantitatively simulating the noise level. It is recognized as a relatively effective and cheap It is also a decision-making management tool that can fully display the noise situation. [0003] At present, urban noise simulation and noise map drawing are ...
