Participatory sensing-based noise collection and display system and participatory sensing-based noise collection and display method

Abstract

The invention discloses a participatory sensing-based noise collection and display system and a participatory sensing-based noise collection and display method. The method comprises the following steps: enabling noise collection applications by all smartphone terminals, collecting noise data of each position at which the corresponding smartphone is located, processing the noise data, and then, sending the processed noise data and positional information to a cloud platform through a wireless network; receiving original noise data sent by all the smartphone terminals through the cloud platform, displaying to the corresponding position in a webpage in real time, meanwhile, storing the original noise data into a text file, processing a period of data to obtain statistical information, and storing into a data base; extracting the corresponding information from the data base by the cloud platform when query operation executed by each smartphone terminal or a user terminal is performed, and sending back the information to the smartphone terminal or displaying to the user terminal through a browser. According to the participatory sensing-based noise collection and display system and the participatory sensing-based noise collection and display method disclosed by the invention, noise collection and display is realized through the participatory sensing system, so that the cost for establishing a noise map is greatly reduced, and the real-time performance and the accuracy of the data are improved.

Description

technical field [0001] The present invention relates to a noise collection and display system and method, in particular to a noise collection and display system and method based on participatory perception. Background technique [0002] Now, a large number of people in the world suffer from serious noise pollution every day, such as noise pollution from cars on roads, noise pollution from crowds in pedestrian streets, noise pollution near airports, and noise pollution around construction sites. Noise pollution can cause very serious damage to the human body, causing hearing impairment, high blood pressure, ischemic heart disease, etc., and can also affect people's mood and sleep quality. [0003] In order to reduce noise pollution, many countries, such as the UK and Germany, have begun to monitor noise pollution. Most of the methods they use are to build a noise map, which shows the noise level of each geographic location. At present, there are two main methods for establi...

Problems solved by technology

These two methods have very serious shortcomings. The first method requires a lot of cost to obtain the original analysis data, and the update of the noise map calculated in this way is very slow (for example, about 5 years). The second method is dedicated The cost of nodes is too high
