Technical Field

[0001] This invention relates to the field of intelligent coal mine operation technology, and in particular to an intelligent coal mine operation collaborative system and method. Background Technology

[0002] In recent years, with the rapid development of technology, the level of intelligence of electromechanical equipment in the coal mining industry has continued to improve. However, in stark contrast, the level of digitalization in human operations and human-machine collaborative operations remains low. This disparity results in a high proportion of maintenance time, long non-production operation time, insufficient human-machine collaborative management in about two-thirds of production support positions, and low human-machine collaborative efficiency. Therefore, how to reduce the proportion of maintenance time and improve human-machine collaborative efficiency and production efficiency has become one of the current research focuses.

[0003] Therefore, the present invention provides an intelligent coal mine operation collaboration system and method. Summary of the Invention

When an anomaly is detected, warnings and anomaly responses are issued. The system also predicts the future failure conditions of operating equipment and takes equipment maintenance strategies to maintain the operating equipment, thereby effectively improving the efficiency of coal mine operations, the efficiency of human-machine collaboration, and the reliability and stability of equipment.

[0005] This invention provides an intelligent coal mine operation collaboration system, comprising:

[0006] Assisted Operations Module: Used to guide target workers in performing coal mine operations using preset intelligent tools;

[0007] Monitoring module: Used to monitor the entire process of coal mine operations performed by target workers in real time, and to issue warnings and take corresponding abnormality responses when an anomaly is detected;

[0008] Predictive maintenance module: It is used to periodically predict the future failure conditions of the operating equipment, obtain the predicted failure results, and then take corresponding equipment maintenance plans to maintain the operating equipment based on the predicted failure results.

[0009] Preferably, the auxiliary operation module includes:

[0010] Login Unit: Used by the target operator to obtain the tool status of the preset smart tool in the display area of ​​the preset smart tool;

[0011] If the current preset smart tool is in an available state, the target operator will perform user authentication and login according to the user login operation of the current preset smart tool;

[0012] If the current preset smart tool is unavailable, the target operator generates a status anomaly report based on the current preset smart tool's number, tool name, and tool status, and sends it to the tool maintenance personnel. Then, the preset smart tool is re-adapted until it is adapted to a preset smart tool with an available status. Finally, the user authentication and login are performed according to the user login operation of the newly adapted preset smart tool.

[0013] Project selection unit: After the target operator successfully logs into the preset smart tool, they can select the target coal mine operation project from the list of designated coal mine operation projects of the target operator according to the project selection operation of the current preset smart tool, and obtain the target operation guidance data.

[0021] Status determination block: Used to preprocess the device status data of the currently operating device to obtain the target status data;

[0022] The target state data is input into a pre-established device state recognition model, and the state recognition result is output.

[0023] Behavior Analysis Block: Based on the status recognition result, when the operating equipment is in an abnormal state, it identifies whether there is a correlation between the current target operator's operation behavior and the abnormal state of the operating equipment based on a preset correlation recognition model, and obtains the correlation recognition result;

[0024] Based on the association identification results, if an association exists, it is determined that the current operation behavior needs to be adjusted, and this is output as a status analysis result.

[0025] If there is no correlation, the current operation behavior is determined to be unnecessary to adjust;

[0026] The operating equipment is subjected to fault identification and judgment according to the equipment fault detection scheme.

[0031] If there is only a single replacement operation in the list of replacement operations, then the current first behavior to be adjusted will be replaced by the replacement operation as an adjustment suggestion output.

[0032] If there are multiple replacement operations in the list of replacement operations, the suitability of each replacement operation is evaluated to obtain the first suitability coefficient.

[0033] The first behavior to be adjusted will be replaced by the replacement operation with the one that has the largest first fit coefficient, and this will be output as an adjustment suggestion.

[0034] Preferably, the formula for calculating the first adaptation coefficient is as follows:

[0035] In the formula, It is represented as the first adaptation coefficient for the i-th replacement operation. This represents the average device status improvement effect value of the i-th replacement operation within a preset time period; This represents the j-th historical replacement parameter of the current first behavior to be adjusted, which is replaced by the i-th replacement operation within a preset time period, where j=1, 2, ... ,m; This represents the total value of the j-th historical replacement parameter that replaces the current first behavior to be adjusted within a preset time period using all replacement operations.

[0040] Based on the first comparison result, if it is determined that the current target worker is engaging in dangerous behavior by not wearing safety equipment, a voice warning will be triggered to the current target worker for not wearing safety equipment.

[0041] Upon receiving a warning that the target worker was not wearing safety equipment, the worker must immediately stop the current coal mine operation and then put on the safety equipment.

[0042] If it is determined that the current target worker has engaged in dangerous or irregular work operations, the dangerous characteristics in the current first comparison result will be used as the matching condition to obtain the correct work operation guidance from the set work operation database.

[0043] At a set frequency, repeatedly issue warnings and corresponding instructions on the correct operation to the current target operator regarding unauthorized or dangerous operations until the target operator corrects the dangerous behavior and completes the operation.

[0044] Upon receiving a warning of a violation or dangerous operation and corresponding instructions for correct operation, the target operator shall immediately correct the current dangerous operation in accordance with the instructions for correct operation.

[0045] Preferably, the predictive maintenance module includes:

[0046] Fault prediction unit: used to periodically collect historical operating data of the operating equipment within a preset time period, perform data preprocessing and feature extraction to obtain the first training data;

[0047] The first training data is used to train the neural network to obtain a fault prediction model;

[0048] Determine the prediction time according to the set prediction time period;

[0049] Using the equipment operation data at the predicted time of operation as input, the fault prediction model is input to obtain the predicted fault occurrence time and predicted fault type, which are then output as the predicted fault result.

[0050] Maintenance unit: Used to determine the maintenance sequence of operating equipment based on the predicted fault occurrence time in the predicted fault results and the importance level of the operating equipment;

[0051] The equipment maintenance content is obtained by filtering the equipment maintenance database using the operating equipment number and the predicted fault type in the predicted fault results as filtering criteria.

[0052] Develop an equipment maintenance plan based on the maintenance sequence and content of the equipment operation;

[0121] Upon receiving a warning that the target worker was not wearing safety equipment, the worker must immediately stop the current coal mine operation and then put on the safety equipment.

[0122] If it is determined that the current target worker has engaged in dangerous or irregular work operations, the dangerous characteristics in the current first comparison result will be used as the matching condition to obtain the correct work operation guidance from the set work operation database.

[0127] In this embodiment, for example, there are dangerous features q1, q2, q3 with similarity values ​​of 0.5, 0.75, and 0.85 with the first behavioral feature z1, respectively. Among them, the similarity values ​​of dangerous features q2 and q3 with the first behavioral feature z1 are greater than the set similarity threshold of 0.7. At this time, it is determined that the behavior of the current target worker is a dangerous behavior, and the dangerous behavior type is the corresponding dangerous behavior type of dangerous features q2 and q3.

[0128] In this embodiment, the set frequency is preset, generally repeating once 10 seconds after the last voice warning ends; the correct operation guidance refers to the correct operation content obtained by matching the dangerous characteristics in the current first comparison result from the set operation database. The set operation database is a database formed by classifying and organizing all correct operation content of coal mine operations performed by operators based on existing safety specifications and operation manuals according to the dangerous characteristics of dangerous behaviors. The correct operation content includes operation steps, safety specifications, correct operation methods, etc.
