[0037] See Figure 1 As shown in the figure, this invention discloses a method for centralized management and control of equipment in a fully mechanized coal mining face, wherein the equipment includes a coal mining machine, a transfer conveyor, a crusher, a conveyor, and power supply equipment, and includes the following steps:

[0038] S1: Obtain the coal mining volume of the coal mining machine, the first distance between the coal mining machine and the transfer machine, the second distance between the transfer machine and the crusher, and the third distance between the crusher and the conveyor; and control the start and stop of the transfer machine, the crusher, and the conveyor based on the coal mining volume, the first distance, the second distance, and the third distance.

[0041] Specifically, the conveyor can be a scraper conveyor. The first working parameter can include the cutting height, cutting depth and working power of the coal mining machine. The second working parameter can include the loading force and power. The third working parameter can include the crushing power and output. The fourth working parameter can include straightness and conveying capacity. The fifth working parameter can include voltage and current.

[0042] In one specific embodiment, S1 includes:

[0043] S11: Obtain environmental parameters of the area where the coal mine fully mechanized mining face is located. The environmental parameters may include: working face temperature, wind speed, and gas concentration. Compare these parameters with the corresponding environmental parameter thresholds. If the environmental parameter thresholds are not exceeded, obtain the coal mining volume of the coal mining machine. If the coal mining volume is less than the first weight threshold, do not start the other equipment.

[0044] S12: When the amount of coal mined is greater than or equal to the first weight threshold and less than the second weight threshold, obtain the first operating speed of the coal mining machine, the second operating speed of the transfer conveyor, the third operating speed of the crusher, and the fourth operating speed of the conveyor at this time.

[0056] In one specific embodiment, S32 further includes:

[0057] S321: Preprocess the first working parameter, the second working parameter, the third working parameter, the fourth working parameter, and the fifth working parameter;

[0058] S322: Construct a fault identification network, and input the preprocessed first working parameter, second working parameter, third working parameter, fourth working parameter and fifth working parameter into the fault identification network for identification, and obtain the corresponding first identification result, second identification result, third identification result, fourth identification result and fifth identification result;

[0059] S323: Construct a video processing network and input the first video data, the second video data, the third video data, the fourth video data, and the fifth video data into the video processing network for processing to obtain the corresponding first video processing result, second video processing result, third video processing result, fourth video processing result, and fifth video processing result;

[0062] By fusing and analyzing the operating parameters and videos of multiple devices, and considering the correlation between operations, the accuracy of fault identification can be improved.
