Noise automatic monitoring equipment point laying method based on noise map

Abstract

The invention provides a noise automatic monitoring equipment point laying method based on a noise map. The method comprises the steps of determining the total number of road traffic monitoring pointsthrough urban scale and urban road network density, and calculating the number of noise monitoring points of each type of road according to the total length of each type of road in a city; then basedon the equivalent sound level and road length of each road in the noise map, and selecting a specific monitored road; then using a road cell in the noise map as a reference, calculating the equivalent sound level of the road cell according to a calculating result in the noise map, combining adjacent road cells with a sound level difference in a threshold; and selecting the central point of each cell after combination as an area monitoring point. The method is applied to laying of the noise automatic monitoring equipment points, and settles problems of automatic monitoring equipment point laying plan shortage, no consideration for current sound environment quality in an artificial monitoring point, over broad method in a specification, etc.

Description

technical field [0001] The present invention relates to the field of environmental noise monitoring, and more specifically, to a point layout method for noise automatic monitoring equipment based on a noise map. Background technique [0002] In recent years, with the development of economy and society, my country's urbanization process has accelerated, the impact of environmental noise pollution has become increasingly prominent, disputes over environmental noise pollution have occurred frequently, and complaints about disturbing residents have remained high. According to the 2017 "Report on the Prevention and Control of Environmental Noise Pollution in China", nationwide, about 43.9% of the total number of environmental complaints are environmental noise complaints, a total of 522,000. The World Health Organization believes that the actual harm of noise pollution not only affects sleep and people's psychology, but also causes various heart, cardiovascular diseases, learning...

Problems solved by technology

[0003] At present, my country's noise monitoring mainly relies on manual monitoring, which requires manual collection of noise sound pressure levels and traffic flow information at various points, which takes a long time and high monitoring costs, and the measurement range of monitoring points is difficult to fully cover the city. Scientific and reasonable monitoring network

[0004] For urban noise monitoring, HJ 640-2012 "Environmental Noise Monitoring Technical Specifications for Urban Acoustic Environment Routine Monitoring" stipulates the monitoring content, point setting and monitoring frequency of urban acoustic environment routine monitoring, but only for Manual monitoring does not consider the point layout method of automatic noise monitoring equipment, and the point layout method in the specification is relatively broad and does not consider the current urban acoustic environment quality. It has certain problems in actual engineering applications, and the point layout method needs to be improved. refinement
