Problems solved by technology

[0004] Therefore, the technical problem to be solved in the embodiment of the present invention is that the conveyor failure detection method in the prior art uses the loudness of the sound produced by the detection roller to identify the failure of the roller. Since the detected sound signal is easily interfered by the noise of other equipment, The failure detection of idlers is not accurate enough

Embodiment 1

[0060] An embodiment of the present invention provides a fault identification method for a conveyor. The conveyor includes a conveyor belt and idler rollers supporting the conveyor belt. The conveyor belt moves through the idler rollers, so that different materials can be transported. Such as figure 1 shown, including the following steps:

[0061] S11. Acquiring sound signals of the surrounding environment of the conveyor. The sound signals of the surrounding environment here are all sound signals within the acceptance range of the sound sensor, including the sound signals of the normal operation of the conveyor, other sound signals from the surrounding environment, and periodic high-frequency sound signals emitted by the faulty idler roller when it rotates , so the sound signal of the surrounding environment is a mixed sound signal.

[0062] S12. Extract the periodic audio signal from the sound signal of the surrounding environment. The periodic sound signal here refers to...

Embodiment 2

[0082] An embodiment of the present invention provides a conveyor fault identification device, such as Figure 5 shown, including:

[0083] The first collection module 51 is used to collect the sound signal of the surrounding environment of the conveyor;

[0084] The extraction module 52 is configured to extract the periodic audio signal from the sound signal of the surrounding environment.

[0085] The first identifying module 53 is configured to identify audio features within a preset frequency according to the periodic audio signal.

[0086] The second identification module 54 is configured to identify the failure of the idler according to the audio signal.

[0087] The fault identification device of the conveyor provided by the embodiment of the present invention also includes:

[0088] The third identification module 55 is used to identify the fault position of the idler roller.

[0089] The first alarm module 56 is configured to send an alarm signal to the fault loca...

Embodiment 3

[0105] An embodiment of the present invention provides a conveyor fault identification system, which is used in the conveyor fault identification method in Embodiment 1, such as Figure 7 shown, including:

[0106] The first sound sensor 71 is used to collect the sound signal of the idler roller. The first sound sensor 71 is used to detect the sound signal of 20kHz-200kHz, and the first sound sensor 71 can identify the fault of the idler roller of the conveyor by detecting the frequency signal.

[0107] Such as Figure 8 As shown, the controller 73 includes a memory 820, a processor 810, and a computer program stored on the memory 820 and operable on the processor 810. When the processor 810 executes the program, it is used to collect the sound of the conveyor according to the first sound sensor 71. The sound signal of the surrounding environment; the periodic audio signal is extracted from the sound signal of the surrounding environment; the audio feature within the preset ...

Abstract

The invention discloses a fault identification method, device and system for a conveyor. the conveyor comprises a conveying belt and a carrier roller for supporting the conveying belt. The fault identification method comprises the following steps: collecting an acoustical signal of the surrounding of the conveyor; extracting a periodic audio signal from the acoustical signal of the surrounding; according to the periodic audio signal, identifying audio features in a preset frequency; and according to the audio features, identifying the fault of the carrier roller. The method can quickly identify the fault of the carrier roller of the conveyor through the audio features in the preset frequency, can avoid other interfering noises, and meanwhile can replace workers to automatically detect thedeflection fault of the conveying belt and the fault of surface temperature anomaly of the conveying belt of the conveyor.

Description

technical field [0001] The invention relates to the technical field of conveyor fault detection, in particular to a conveyor fault identification method, device and system. Background technique [0002] Conveyors can be used as the most important bulk material conveying and loading and unloading equipment, which are widely used in mining, metallurgy, building materials, chemical industry, electric power, food processing and other industrial fields, for example: in coal mines, metal mines, iron and steel enterprises, ports, cement A large number of applications of conveyors can be seen in factories and other places. The conveyor mainly includes the conveyor belt and the idler roller supporting the conveyor belt. The idler roller is located directly below the conveyor belt. The conveyor belt is attached to the idler roller to transport materials. Due to the long-term operation of the conveyor, various failures will also occur. Among them, the failure of the idler roller is mo...
