The 4g router with ethernet in environmental noise system

The sources of noise are mainly divided into the following types:

1. Automobile, factory machinery and other mechanized equipment noise, car whistle, large truck noise, factory large mechanized equipment, etc.;

2. Construction noise, human society in great strides forward, a high-rise building, construction and decoration issued a large number of huge and harsh noise;

3. The noise of human life. With the increase of human income and the improvement of living standard, the installation and use of air conditioning are increasing every year; Human life is becoming more and more comfortable, and there are more and more literary and artistic activities. Human life garbage is increasing day by day, household goods update frequently, all kinds of hawkers full of streets and lanes.

These are the noise pollution that people will encounter in their lives. It is imperative to solve the noise pollution and give people a quiet and healthy living environment. Therefore, the noise monitoring project is put forward.

System introduction

The noise monitoring system is mainly used to monitor the noise of residential areas, schools, hospitals, nursing homes and other places that need quiet. The decibel number of current noise is mainly collected by the noise sensor and uploaded to the monitoring center, which monitors, stores, calculates,

Display, release; The sensor acquisition terminal collects the current noise information in real time, and each monitoring point is equipped with a wireless data transmission terminal, which transmits the information collected by the sensor to the central platform in real time through the 3g 4g router with ethernet cellular network.

The service center sets up a system platform on the server, which receives the real-time noise information reported by the wireless data transmission terminal of each monitoring point, stores and calculates the daily average noise value in real time or performs other operations. At the same time, an LED display screen is set up in a prominent position of each monitoring point. Each LED display screen is equipped with a wireless data transmission terminal, which can receive information from the platform and display it on the screen to remind people of the current noise value and to remind people to keep quiet in the public area.

System function

Noise monitoring is real-time and intuitive, so residents can grasp the current noise situation and the average noise value of the area in time. At the same time, according to the monitoring situation of each point, the monitoring center will distribute the current noise situation, average noise of time period, daily average noise and other information to each monitoring point after calculation, and display it on the corresponding LED screen for residents to view; Noise map can be formed to clearly display the noise situation of each monitoring point, as well as the noise pollution distribution map of the whole community or even the whole city; The platform is B/S architecture platform, and users can remotely browse, manage and publish noise information through the browser or APP installed on the smart handheld terminal.
