DETAILED DESCRIPTION

[0037] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] Belt conveyors for coal mines have the characteristics of large transportation volume, complex working environment, strong carrying capacity, and long transportation distance. Belt conveyors for coal mines can not only be used in the production and processing of coal, but also in the production and processing of other minerals. In terms of energy consumption, they can effectively reduce energy consumption and provide economic benefits. Compared with automobile transportation, they can save energy and protect the environment. In addition, in terms of maintenance, belt conveyors for coal mines have the characteristics of low maintenance and relatively simple maintenance, which is also favored by mining production and processing companies.

[0040] Belt conveyors are often used in coal mining operations. Due to the long transmission distances and the location of the belt conveyor underground, it is difficult to locate the fault point when a belt conveyor fails, making it difficult to promptly notify maintenance personnel for repairs. Related technologies routinely inspect various locations on the belt conveyor to detect faults, significantly increasing labor costs and resulting in low inspection efficiency, making it difficult to promptly detect belt conveyor faults. Therefore, to address these deficiencies, the present invention provides a mine belt fault diagnosis system based on audio analysis technology.

[0041] Figure 1 FIG. 1 is a block diagram of a mine belt fault diagnosis system based on audio analysis technology according to an exemplary embodiment. Figure 1 As shown, the system is used for belt conveyor fault analysis and includes the following modules.

[0042] The central processing module 1 is used to receive the warning number sent by the audio analysis module and send the warning number, wherein.

[0043] In the embodiment of the present application, the central processing module 1, also known as the central processing unit (CPU), is the computing core and control core of a computer and the final execution unit for information processing and program running. The central processing module 1 is the hub of the entire system and is responsible for connecting other modules in the system and transmitting information between modules.

[0044] Optionally, the model of the central processing system 1 is ARM9.

[0045] The audio analysis module 2 is used to collect audio data from monitoring points on the belt to perform audio analysis to obtain an early warning number, wherein the audio analysis module includes at least one audio monitoring submodule.

[0046] In an embodiment of the present application, at least one monitoring point is set on the belt conveyor, and the audio data of the monitoring point is collected by the audio monitoring submodule for analysis to determine whether a fault occurs at the monitoring point. If a fault occurs, the number of the audio monitoring submodule is determined to be a warning number, and the warning number is sent to the central processing module 1. The setting method of the monitoring point can be determined by the implementer according to actual conditions. In one possible embodiment, the monitoring points are set at equal intervals on the belt, with an interval of 10 cm between each monitoring point. One or more audio monitoring submodules are set at each monitoring point. Since the audio data collected by one audio monitoring submodule may have errors, in order to reduce errors and improve the accuracy of audio analysis, multiple audio monitoring submodules can be set at the monitoring point.

[0047] In a possible embodiment, three audio monitoring submodules are provided at each monitoring point.

[0048] The operation status monitoring module 3 is used to obtain the operation status data of the belt and send it to the central processing module.

Based on the warning number, number recognition module 5 retrieves the corresponding audio monitoring submodule and further determines the monitoring point where the fault occurred. To notify maintenance personnel of the fault location, number recognition module 5 generates a warning signal and sends it to audio and visual alarm module 6 and abnormality warning module 7.

[0053] The sound and light alarm module 6 is used to generate an alarm according to the early warning signal sent by the number recognition module.

[0054] In the embodiment of the present application, the setting of the sound and light alarm module 6 can provide early warning to the staff around the belt conveyor, informing the staff that the belt has failed, thereby reducing safety hazards. The sound and light alarm module 6 uses a sound and light alarm, which is also called a sound and light alarm signal.

[0061] The marking module 10 is used to mark the audio monitoring submodule corresponding to the monitoring point to generate a number for the audio monitoring submodule, and send the number to the central processing module and the audio analysis module.

[0062] In the embodiment of the present application, in order to distinguish the audio monitoring submodules corresponding to different monitoring points, the audio monitoring submodule is marked and encoded by the marking module 10, the number corresponding to the audio monitoring submodule is obtained, and the number is stored in the storage module 4.

[0068] In the embodiment of the present application, after the audio data sent by the audio monitoring submodule 22 is received by the audio analysis module 21, the audio data is compared and analyzed with the normal audio data of the monitoring point pre-stored in the audio database 25. The audio database 25 contains the normal audio data of the belt conveyor obtained by pre-detection, as well as the reference power data corresponding to the normal audio data, and the power deviation threshold. During the analysis process, the average power corresponding to the audio data collected by the audio monitoring submodule corresponding to the monitoring point is obtained. If the difference between the average power value of the monitoring point and the reference power data is less than or equal to the power deviation threshold, it is determined that no abnormality has occurred at the monitoring point. If the difference between the average power value of the monitoring point and the reference power data is greater than the power deviation threshold, the audio judgment submodule 23 determines that a fault problem has occurred at the monitoring point, and then the signal is fed back to the microprocessor 24.
