Description

Technical Field

[0001] The invention belongs to the technical field of coal mine safety management, in particular to a monitoring and inspection system and an inspection method thereof applied to coal mine safety management. Background Art

[0002] In the coal mining industry, safety management is a vital link. However, the traditional coal mine safety management method mainly relies on manual inspections and paper records, which has many disadvantages. First, manual inspections are difficult to ensure the comprehensiveness and timeliness of inspections. Inspectors may miss certain key areas due to negligence or fatigue, resulting in safety hazards that cannot be discovered in time. Secondly, paper records are easy to forge and tamper with, and it is difficult to ensure the authenticity and integrity of the data, which brings great risks to coal mine safety management. In addition, the traditional coal mine safety management method lacks real-time and intelligence, and cannot analyze and process inspection data in a timely manner, making it difficult to provide effective decision-making support for coal mine safety management.

[0003] With the continuous development of science and technology, some coal mines have begun to try to introduce electronic inspection systems, but these systems often have problems such as single function, low positioning accuracy, and insufficient data analysis capabilities, and cannot meet the comprehensive needs of coal mine safety management.

[0004] Therefore, those skilled in the art have proposed a monitoring and inspection system and an inspection method thereof for coal mine safety management to solve the problems raised by the background technology. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a monitoring and inspection system and an inspection method applied to coal mine safety management, so as to solve the problems often existing in the prior art such as single function, low positioning accuracy, insufficient data analysis capability, and inability to meet the comprehensive needs of coal mine safety management.

[0011] Among them, the supervision server includes a first identity information acquisition module, a sign-in module, a reminder module, an alarm module, a data statistical analysis module and a setting module. The first identity information acquisition module is used to obtain the head portrait information and fingerprint information of the inspectors who sign in at the well. The sign-in module is used to identify and record the basic information of the inspectors preset on the identity card held by the inspectors, and perform inspection matching and sign-in based on the head portrait information and fingerprint information of the inspectors.

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a framework diagram of the monitoring and inspection system applied to coal mine safety management of the present invention. DETAILED DESCRIPTION

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] Embodiment: The present invention provides a monitoring and inspection system for coal mine safety management, such as Figure 1 As shown, including:

[0032] Supervision server, used to receive, process and analyze inspection data;

[0033] The patrol device is used to monitor the environmental parameters and structural parameters of the well in real time and store the data in the memory card;

[0034] Multiple inspection substations are set up at key locations underground to confirm the identity of inspection personnel and upload inspection data;

[0035] Identity cards, associated with patrol personnel, are used to match check-ins and patrols above and below the well;

[0036] Among them, the supervision server includes a first identity information acquisition module, a sign-in module, a reminder module, an alarm module, a data statistical analysis module and a setting module. The first identity information acquisition module is used to obtain the head portrait information and fingerprint information of the inspectors who sign in at the well. The sign-in module is used to identify and record the basic information of the inspectors preset on the identity card held by the inspectors, and perform inspection matching and sign-in based on the head portrait information and fingerprint information of the inspectors.

[0037] As can be seen from the above, through the set supervision server, patrol inspection device, multiple patrol substations and identity cards, in conjunction with the first identity information acquisition module, sign-in module, reminder module, alarm module, data statistics analysis module and setting module in the supervision server, the double confirmation of the identity of the patrol personnel (matching of identity card information with headshot and fingerprint information) is achieved, ensuring the authenticity and integrity of the patrol data. At the same time, the patrol inspection device monitors the environmental parameters and structural parameters of the underground in real time, improves the comprehensiveness and accuracy of the patrol inspection, effectively avoids empty shifts and missed inspections, provides strong technical support for coal mine safety management, and ensures the safety and stability of coal mine production.

[0038] Furthermore, the inspection device is also provided with a hanging rope, so that the inspection personnel can carry and operate it conveniently.

[0039] From the above, it can be seen that the hanging rope set on the patrol device greatly facilitates the carrying and operation of the patrol personnel, so that the patrol personnel can easily hang the patrol device on their bodies when working underground, which not only frees their hands and improves work efficiency, but also ensures the stability and safety of the patrol device in complex environments, thereby ensuring the continuity of the inspection work and the reliability of the data.

[0040] Furthermore, the inspection device includes a positioning unit and a timing unit, which are used to monitor the underground inspection path and the residence time of the monitoring points on the inspection path in real time, and analyze the preset underground inspection path and the residence time of the monitoring points on the inspection path to avoid the phenomenon of empty shifts and missed inspections by the inspection personnel, that is, the inspection route is optimized by using a path planning algorithm to ensure that the inspection personnel can complete the inspection task efficiently and accurately. The formula of the path planning algorithm includes:

[0041] d(v)=minu∈V,(u,v)∈E[d(u)+w(u,v)];

[0042] Among them, d(v) represents the shortest path length of node v, V represents the node set, E represents the edge set, and w(u,v) represents the weight of edge (u,v).

[0043] As can be seen from the above, the positioning unit and timing unit equipped by the patrol device, combined with the path planning algorithm, can monitor and analyze the underground inspection path and the dwell time of the monitoring point in real time, effectively avoiding the phenomenon of empty shifts and missed inspections by the patrol personnel. By accurately calculating the shortest path and weight between each node and optimizing the inspection route, it not only ensures that the patrol personnel can complete the inspection task efficiently and accurately, but also improves the coverage and timeliness of the inspection, providing more comprehensive and reliable data support for coal mine safety management.

[0044] Furthermore, in order to optimize the positioning accuracy of the patroller and ensure that the real-time monitoring of the underground patrol path and the monitoring point residence time data is more accurate, a weighted centroid positioning algorithm is used to optimize the positioning accuracy in combination with the underground wireless signal propagation model. The formula of the weighted centroid positioning algorithm includes:

[0045]

[0046] Among them, (x, y) is the estimated position of the patroller, (x i ,y i ) is the position of the i-th reference node, w i is the weight of the i-th reference node (based on factors such as signal strength and distance).

[0047] From the above, it can be seen that the weighted centroid positioning algorithm, combined with the underground wireless signal propagation model, can significantly improve the accuracy of the real-time monitoring of the underground inspection path and the monitoring point residence time data. By comprehensively considering the position and weight of multiple reference nodes (based on signal strength, distance and other factors), the weighted centroid positioning algorithm can more accurately estimate the actual position of the inspection device, thereby ensuring the reliability and effectiveness of the inspection data, and providing more accurate data support for coal mine safety management.

[0048] Furthermore, the supervision server also includes an alarm module for issuing an alarm reminder when the inspection data is abnormal or the inspection personnel fail to inspect according to regulations. The alarm module uses the 3σ principle algorithm for abnormality detection. The formula of the 3σ principle algorithm includes:

[0049] |x-μ|>3σ;

[0050] Among them, x is the data value monitored in real time, μ is the mean of the data, and σ is the standard deviation of the data; if the above inequality is satisfied, x is considered to be an outlier.

[0051] As can be seen from the above, setting up an alarm module in the supervision server and using the 3σ principle algorithm for anomaly detection can achieve real-time monitoring and accurate judgment of inspection data. When the difference between the real-time monitored data value and the mean of the data exceeds three times the standard deviation, it can be regarded as an abnormal value, thereby triggering an alarm reminder. This method can quickly detect abnormal conditions in inspection data or the behavior of inspection personnel not conducting inspections in accordance with regulations, ensure the timeliness and effectiveness of coal mine safety management, and avoid potential safety hazards.

[0052] Furthermore, in the supervision server, for analyzing the inspection data, a time series prediction algorithm is used to mine and analyze the historical inspection data, predict future safety trends, and provide decision support for coal mine safety management. The formula of the time series prediction algorithm includes:

[0053] φ(B)y t =c+θ(B)ε t ;

[0054] Among them, φ(B) and θ(B) are the polynomials of the autoregressive and moving average parts, respectively, and y t represents the value of the time series at time t, c is a constant term, ε t is a white noise sequence.

[0055] From the above, we can see that in the supervision server, the use of time series prediction algorithm to mine and analyze historical inspection data can accurately predict future safety trends and provide strong decision-making support for coal mine safety management. The algorithm fully considers the inherent laws and correlations of time series data by constructing polynomial models of autoregression and moving average parts, so as to accurately predict future changes in inspection data. This prediction capability helps coal mine managers to promptly discover potential safety hazards, formulate reasonable safety management measures, and improve the safety and stability of coal mine production.

[0056] Furthermore, the monitoring and inspection system applied to coal mine safety management of the embodiment is compared with the current traditional coal mine safety management method (comparative example), and the following table is obtained:

[0057]

[0058] It can be seen from the above table that the monitoring and inspection system of this embodiment is superior to the traditional coal mine safety management method in terms of comprehensiveness, timeliness, positioning accuracy, data authenticity, intelligence, work efficiency and safety, and can significantly improve the level of coal mine safety management and ensure the safety and stability of coal mine production.

[0064] The patrol device monitors the environmental parameters and structural parameters underground in real time and stores them in the memory card. When it reaches the surface, it is directed to the supervision server for data analysis to determine whether the patrol personnel have fabricated the monitoring data.
