A multi-channel wireless noise testing method and device

Abstract

The invention relates to a multi-channel wireless noise testing method and device. The multi-channel wireless noise testing device comprises noise testing modules, a ZigBee communication module, and a WiFi communication module, wherein each noise testing module comprises a microphone unit, a core control circuit, a noise testing device front-end equipment power supply module, and a support; the ZigBee communication module comprises antennas, front-end ZigBee communication modules, and a back-end ZigBee communication module; the WiFi communication module comprises front-end WiFi communication modules, and a back-end WiFi communication module; the noise testing modules distributed in different sound fields simultaneously transmit original data to a multi-channel noise data statistics and analysis module through WiFi or ZigBee; and the data statistics and analysis module analyzes the received original data through software to obtain relevant noise parameters. The method and device provided by the invention has the advantages that noise testing and monitoring can be carried out through multiple channels simultaneously, so that all-weather and real-time noise testing and monitoring through the multiple testing channels can be achieved.

Description

technical field [0001] The invention relates to a testing method and device, in particular to a multi-channel wireless noise testing method and device. Background technique [0002] With the continuous development of modern industry, environmental pollution has also emerged. As a kind of environmental pollution, noise pollution has become a major hazard to human society. Noise pollution, water pollution, air pollution, and solid waste pollution are known as four major environmental problems worldwide. [0003] The currently widely used noise testing method is to use a noise measuring instrument to complete it by artificial means. When it is necessary to continuously monitor the noise within a period of time, the monitoring personnel need to stay at the test point for a long time and perform instrument operations from time to time. Sometimes, in order to obtain real and complete noise data, in order to realize the statistics, evaluation and noise control of noise data, it i...

AI Technical Summary

Problems solved by technology

When it is necessary to continuously monitor the noise within a period of time, the monitoring personnel need to stay at the test point for a long time and perform instrument operations from time to time

Sometimes, in order to obtain real and complete noise data, in order to realize the statistics, evaluation and noise control of noise data, it is necessary to conduct noise tests on the monitoring objects for 24 hours or more. At this time, the work of noise monitoring personnel is It is very hard work and consumes a lot of manpower and material resources

Technicians usually require a large number of data connection lines to detect the noise inside the building to connect the sound level meter (microphone) and the data receiving end, which makes the spatial layout of the connecting lines troublesome, and it is also impossible to realize the simultaneous detection of multiple noise collection points by the control end Accurate data collection and synchronous processing of data, so that the detection efficiency and data quality cannot be substantially guaranteed
