Sound based coal mine tunnel abnormity monitoring device and method

Abstract

The invention discloses a sound based coal mine tunnel abnormity monitoring device and method, and belongs to the technical field of automatic detection; the invention provides the sound based deviceand method, the expansibility of the device and the method is strong, and the abnormal state of a tunnel can be discovered in time; the technical scheme is as follows: the device is arranged in the coal mine tunnel and comprises a host, the host is provided with a metal shell, the metal shell is internally provided with a data storage module, a sound card module, a data processing module, and a microphone array arranged on the side surface of the metal shell, the microphone array is used for acquiring the sound in the coal mine tunnel, and transmitting the acquired sound to the sound card module; the sound card module converts an acoustical signal into an electric signal through acoustoelectric conversion, then the electric signal is transmitted to the data processing module, the data processing module processes and analyzes the electric signal through sound training and sound recognition, judges whether an abnormity occurs, and stores an analysis result in the data storage module.

Description

technical field [0001] The invention discloses a sound-based coal mine tunnel anomaly monitoring device and method, belonging to the technical field of automatic detection. Background technique [0002] In today's information society, sound, as one of the carriers of information that coexists with text, images, and videos, is widely distributed in daily production and life. The information it transmits accounts for a large proportion of all information, and it is also the basis of human communication. basic way. As an important source of information for humans to perceive the environment, sound can well reflect the sound events in the environment and judge whether the events in the environment are normal or not. In recent years, people are gradually entering into more in-depth research on abnormal voice recognition technology. Due to the complex and diverse characteristics of sounds in different environments, the wide range of sound frequency bands involved, the superposit...

Problems solved by technology

With the advancement of unmanned mines, the number of inspection personnel in coal mines is gradually decreasing, which makes it more difficult to perform inspections that cannot be done completely.

Abnormal situations in various roadways of coal mines occur from time to time. Once the inspection personnel cannot arrive at the scene in time, the abnormal situation will aggravate, which may cause large economic losses or even personal injuries to the coal mine.
