[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, a coal mine air compressor automatic control system includes: a data acquisition unit 10, used to acquire coal mine excavation data; a model updating unit 20, used to update the coal mine excavation model according to the coal mine excavation data; an environment prediction unit 30, used to acquire personnel flow information in the coal mine, and predict the internal environment of the coal mine according to the personnel flow information and the coal mine excavation model; a detection unit 40, used to perform environmental detection on the internal environment of the coal mine based on the coal mine excavation model; and a control unit 50, used to control the coal mine air compressor to work when the internal environment of the coal mine does not meet the set requirements.

[0022] In this embodiment, the coal mine excavation data can be acquired through the data acquisition unit 10, and the coal mine excavation data may include excavation depth data, excavation personnel data, personnel flow data, excavation time, coal mine gas leakage rate, etc. Then, the preset initial excavation model can be further updated through the model updating unit 20 according to the coal mine excavation data to obtain the coal mine excavation model. Based on the initial gas composition in the coal mine, such as oxygen content, and based on the excavation personnel data, personnel flow data and excavation time, etc., the gas distribution of the coal mine excavation model after the update is predicted through the environment prediction unit 30, that is, the internal environment of the coal mine is predicted. Then, the detection unit 40 can be used to detect the gas costs of each gas in the predicted internal environment of the coal mine. When, for example, the oxygen content does not meet the standard, the control unit 50 will control the coal mine air compressor to work, and the external air will be exchanged with the internal environment gas of the coal mine.

[0023] In one embodiment of the present invention, the coal mine excavation data acquired by the data acquisition unit 10 includes excavation depth data, excavation personnel data, personnel flow data, excavation time, and coal mine gas leakage rate.

[0024] In this embodiment, the excavation depth data may include modeling information such as the excavation length, width and height. The excavation personnel data, personnel flow data and excavation time may be further processed into oxygen consumption information in the coal mine. The coal mine gas leakage rate may further update the internal environmental gas distribution information of the coal mine based on the oxygen consumption information in the coal mine.

[0025] In one embodiment of the present invention, the model updating unit 20 includes: a data extraction module, used to extract modeling information from the coal mine mining data; and a model processing module, used to process the preset initial mining model in the coal mine mining space according to the modeling information, and update the coal mine mining model.

[0026] In this embodiment, when data extraction and modeling are performed, the modeling information in the coal mine excavation data can be extracted through the data extraction module, wherein the modeling information mainly includes the length, width and height of the excavation, etc. Then, according to the modeling information, the preset initial mining model can be further expanded and constructed through the model processing module based on the preset initial mining model to update the real-time coal mine excavation model, thereby facilitating the prediction of the gas distribution in the coal mine excavation space according to the coal mine excavation model.

[0027] In one embodiment of the present invention, the model processing module includes: a location information acquisition module, which is used to obtain the point coordinates of modeling information based on a preset initial mining model; a mining modeling module, which is used to create a new regional model for the mining completed area according to the modeling information; and an updating module, which is used to add the new regional model to the initial mining model in sequence according to the new regional model and the point coordinates of the modeling information, so as to update the coal mine mining model.

[0028] In this embodiment, during the model processing, the coal mining model is an initial mining model in the initial state. Therefore, the location information acquisition module can be used to obtain the point coordinates of the modeling information, and the point coordinates of the modeling information correspond to the corresponding points in the preset initial mining model. The mining modeling module can be used to further create a new regional model based on the modeling information, and the new regional model corresponds to the area that has been mined during the coal mining process. Then, the initial mining model is spatially expanded based on the new regional model and the corresponding point coordinates of the modeling information through the updating module, so as to update the coal mining model.

[0029] In one embodiment of the present invention, the environmental prediction unit 30 includes: a distribution prediction module, which is used to predict the oxygen distribution data of personnel in the coal mine along the flow route in the coal mine according to the personnel flow information in the coal mine; and a prediction update module, which is used to update the initial coal mine internal environment in the coal mine mining model according to the oxygen distribution data and predict the internal environment of the coal mine.

[0030] In this embodiment, during the environmental prediction process, the distribution prediction module can be used to predict the oxygen distribution data in the coal mine according to the flow of workers in the coal mine. That is, when personnel flow, the oxygen distribution at each location is different. By counting the oxygen distribution data along the flow route in the coal mine, the prediction update module coal mine mining model can be used to update the oxygen distribution data based on the initial coal mine internal environment, thereby predicting the internal environment of the coal mine.

[0031] In one embodiment of the present invention, the distribution update module includes: a consumption prediction module, which is used to determine the flow route of personnel in the coal mine along the coal mine based on the personnel flow information in the coal mine, and predict the oxygen consumption data on the flow route; and a distribution processing module, which is used to process the initial oxygen distribution data in the initial coal mine internal environment in the coal mine mining model according to the oxygen consumption data, and predict the oxygen distribution data of personnel in the coal mine along the flow route in the coal mine.

[0032] In this embodiment, during the updating of oxygen distribution data, the consumption prediction module is used to predict the oxygen consumption data of the corresponding personnel at each point along the flow route in the coal mine according to the flow information of the personnel in the coal mine, thereby obtaining the distribution data of the oxygen consumption data along the flow route in the coal mine. Furthermore, the distribution processing module is used to update the initial coal mine internal environment in the coal mine mining model based on the initial oxygen distribution data according to the oxygen consumption data, thereby obtaining the oxygen distribution data of the personnel in the coal mine along the flow route in the coal mine.

[0033] In one embodiment of the present invention, the prediction update module includes: a first update processing module, which is used to adjust and obtain the first oxygen distribution data in the coal mine excavation model according to the oxygen distribution data and the infiltration rate in the coal mine excavation model update direction.

[0034] In this embodiment, the update along with the excavation depth can be realized through the first update processing module, and the first oxygen distribution data in the coal mine excavation model updated along with the excavation depth can be further determined according to the infiltration rate corresponding to the excavation depth.

[0035] In one embodiment of the present invention, the prediction update module also includes: a second update processing module, which is used to obtain the second oxygen distribution data in the coal mine excavation model based on the first oxygen distribution data in the coal mine excavation model and the gas leakage rate of each point in the coal mine.

[0036] In this embodiment, during the coal mining process, the gas in the coal mine will also exchange gas with the outside, thereby generating a gas leakage rate. Therefore, the second oxygen distribution data in the coal mine mining model in the corresponding time period can be determined based on the first oxygen distribution data in the coal mine mining model and the corresponding gas leakage rates at each point.

[0037] In an embodiment of the present invention, the detection unit 40 is further used to determine whether the corresponding oxygen distribution data in the internal environment of the coal mine based on the coal mine excavation model exceeds a set value.

[0038] In this embodiment, by determining whether the oxygen distribution data corresponding to each point area exceeds the set value to control the operation of the coal mine air compressor, it is possible to facilitate timely adjustment of the gas environment in the coal mine and avoid danger when working in the coal mine.

[0039] Specifically, the control unit 50 is also used to control the operation of the coal mine air compressor when the corresponding oxygen distribution data in the internal environment of the coal mine exceeds a set value.
