Mobile noise detection system

Abstract

The invention relates to a mobile noise detection system. The mobile noise detection system includes noise monitoring sensors, transmitting communication modules, a receiving communication module, an acquisition computer and a noise monitoring system, wherein the noise monitoring sensor is connected with the transmitting communication modules, the transmitting communication modules are wirelessly connected with the receiving communication module, the receiving communication module is connected with the acquisition computer, and the acquisition computer is connected with the noise monitoring system through a local area network. According to the mobile noise detection system of the invention, multi-point distribution of the noise monitoring sensors can be realized, and therefore, the integrity of test data can be ensured, and the continuity of the operation of the noise monitoring sensors can be also ensured; noise acquisition points can be networked easily, and a wide coverage area can be provided; the acquisition computer acquires the data of the noise monitoring sensors in a TCP manner, and therefore, centralized transmission of the data can be realized; and the noise monitoring system can monitor, store, distribute and statistically analyze upload data, and therefore, acquired data can be applied timely and sufficiently.

Description

technical field [0001] The invention belongs to the technical field of acoustic testing and signal processing, and in particular relates to a mobile noise detection system. Background technique [0002] All sound level testing equipment currently on the market is a hand-held integrating sound level meter, and most of them use sound power level for testing. The hand-held integrating sound level meter is more convenient to carry and more flexible, but because the hand-held integrating sound level meter needs to be hand-held by the tester to collect data, when the collected and stored data reaches a certain amount, it will no longer be stored, and the displayed value will be fixed as the last stored value. If you want to continue the test, you need to clear the data and test again. [0003] Hand-held integrating sound level meters cannot conduct effective long-term uninterrupted tests on a specific sound source, and it is even more impossible to test occasional sound sources. ...

[0003] Hand-held integrating sound level meters cannot conduct effective long-term uninterrupted tests on a specific sound source, and it is even more impossible to test occasional sound sources

However, the analysis system of the hand-held integral sound level meter can only simply calculate the average value, and cannot perform long-term and complicated calculations. The sudden high sound decibel cannot be eliminated. When the battery is out of power, the hand-held integrating sound level meter will automatically shut down and must be replaced with a new battery before it can be used
