Description

Technical Field

[0001] This invention relates to the field of mine safety technology, and in particular to an electrical equipment control method, device and storage medium. Background Technology

[0002] Rockburst disasters are a type of dynamic disaster characterized by their sudden occurrence. Secondary disasters are prone to occur after a rockburst, and the damage caused by these secondary disasters to workers and electrical equipment often exceeds that caused by the rockburst itself. Therefore, timely early warning systems for rockburst events are necessary.

[0003] In related technologies, methods such as sound wave detection, microseismic analysis, computed tomography (CT), coal seam stress analysis, or electromagnetic radiation analysis are used to provide early warnings of rockburst accidents. However, the warning time of these technologies is highly uncertain. For example, a warning may be issued but no disaster occurs; a warning may be issued but a disaster occurs many days later; or a warning may be issued and a disaster occurs immediately afterward. Therefore, these technologies cannot provide timely and accurate early warnings of rockburst accidents, and thus cannot meet the needs of preventing secondary disasters caused by rockbursts. Summary of the Invention

[0004] This invention provides an electrical equipment control method, apparatus, and storage medium to solve the technical problems that have arisen in the aforementioned related technologies.

[0005] To address this, the present invention proposes an electrical equipment control method that, based on preset rules and longitudinal wave parameter sequences, quickly determines whether a rockburst has occurred. This allows for the issuance of a blocking signal to equipment around the rockburst location before the arrival of a powerful transverse wave, cutting off power and stopping mechanical equipment operation. This improves the real-time performance of the blocking, effectively reducing the likelihood of secondary disasters occurring at the rockburst site. This method plays a positive role in promoting the prevention and control of rockburst disasters and offers significant technical, economic, and safety benefits.

[0023] Identify abnormal parameters in the longitudinal wave parameter sequence that exceed the first associated threshold in the linkage threshold;

[0024] Determine whether the P-wave parameters adjacent to the abnormal parameters in the P-wave parameter sequence exceed the second correlation threshold in the linkage threshold;

[0025] If the longitudinal wave parameter adjacent to the abnormal parameter exceeds the second associated threshold in the linkage threshold, the above steps are repeated until all associated thresholds in the linkage threshold are judged or a certain associated threshold does not have a corresponding abnormal parameter, so as to obtain all abnormal parameters in the longitudinal wave parameter sequence.

[0026] Identify the target vibration sensor corresponding to all the abnormal parameters;

[0027] The area corresponding to the target sensor is determined as the target area where anomalies exist.

[0032] The sending module is used to send a locking command to the device to be controlled within the target area to lock the device to be controlled.

[0033] The computer device proposed in the third aspect of the present invention includes a memory, a processor, and a computer program stored in the memory and executable on the processor.

This effectively reduces the possibility of secondary disasters occurring at the site after a rockburst, playing a positive role in promoting the prevention and control of rockburst disasters, and has significant technical, economic, and safety benefits.

[0036] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0038] Figure 1 This is a flowchart illustrating an electrical equipment control method according to an embodiment of the present invention.

[0039] Figure 2 This is a schematic diagram of the structure of an electrical equipment control device according to another embodiment of the present invention. Detailed Implementation

[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The electrical equipment control method and apparatus of the present invention are described below with reference to the accompanying drawings.

[0042] Figure 1 This is a flowchart illustrating an electrical equipment control method according to an embodiment of the present invention, applied to a monitoring substation, such as... Figure 1 As shown, it may include:

[0043] Step 101: Obtain measurement parameters collected by at least one vibration sensor.

[0044] In an embodiment of the present invention, each monitoring substation may be connected to at least one vibration sensor, and each vibration sensor may collect measurement parameters of the corresponding area. Furthermore, in an embodiment of the present invention, each monitoring substation may also be connected to at least one device to be controlled.

[0045] Furthermore, in embodiments of the present invention, the aforementioned measurement parameters may include vibration velocity and / or vibration acceleration.

[0046] Step 102: Process the collected measurement parameters to obtain the longitudinal wave parameter sequence corresponding to the measurement parameters.

[0047] In one embodiment of the present invention, after obtaining the measurement parameters as described above, the collected measurement parameters can be processed to obtain the longitudinal wave parameter sequence corresponding to the measurement parameters.

[0048] Specifically, in embodiments of the present invention, the method for processing the collected measurement parameters to obtain the longitudinal wave parameter sequence corresponding to the measurement parameters may include: processing the collected measurement parameters based on a unified parameter standard to obtain processed measurement parameters; and obtaining the corresponding longitudinal wave parameter sequence based on the processed measurement parameters according to the arrangement position of the vibration sensor.

[0049] In the embodiments of the present invention, the aforementioned unified parameter standard can be based on consistent data types. For example, all collected measurement parameters can be converted into corresponding integers, or all collected measurement parameters can be converted into decimals with two decimal places.

[0050] Furthermore, in embodiments of the present invention, the processed measurement parameters can be sorted according to the lateral or vertical arrangement of the vibration sensors to obtain the corresponding longitudinal wave parameter sequence.

[0051] Step 103: Based on the longitudinal wave parameter sequence, determine the range of the target area where anomalies exist according to preset rules.

[0052] In embodiments of the present invention, the aforementioned preset rules may include a linkage threshold or a global threshold.

[0053] Furthermore, in the embodiments of the present invention, the methods for determining the range of target areas with anomalies according to the preset rules are also different for different preset rules.

[0054] Specifically, in an embodiment of the present invention, when the preset rule is a global threshold, the method for determining the range of the target region with anomalies based on the longitudinal wave parameter sequence and the preset rule may include the following steps:

[0055] Step 1031: Identify the abnormal parameters in the longitudinal wave parameter sequence that exceed the global threshold;

[0056] Step 1032: Determine the target vibration sensor corresponding to the abnormal parameters;

[0057] Step 1033: Determine the area range corresponding to the target sensor as the target area range where anomalies exist.

[0058] In an embodiment of the present invention, when the preset rule is a global threshold, all parameters in the aforementioned longitudinal wave parameter sequence correspond to the same threshold. That is, vibration velocity corresponds to the same vibration velocity threshold and / or vibration acceleration corresponds to the same vibration acceleration threshold. Based on this, parameters in the longitudinal wave parameter sequence that exceed the global threshold can be identified as abnormal parameters.

[0059] Furthermore, in another embodiment of the present invention, when the preset rule is a linkage threshold, the method for determining the range of the target area with anomalies based on the longitudinal wave parameter sequence and the preset rule may include the following steps:

[0060] Step 1: Identify the abnormal parameters in the longitudinal wave parameter sequence that exceed the first associated threshold in the linkage threshold;

[0061] Step 2: Determine whether the P-wave parameters adjacent to the abnormal parameters in the P-wave parameter sequence exceed the second correlation threshold in the linkage threshold.

[0062] Step 3: If the adjacent P-wave parameters of the abnormal parameter exceed the second associated threshold in the linkage threshold, repeat the above steps until all associated thresholds in the linkage threshold are judged or a certain associated threshold does not have a corresponding abnormal parameter, and obtain all abnormal parameters in the P-wave parameter sequence.

[0063] Step 4: Identify the target vibration sensor corresponding to all abnormal parameters;

[0064] Step 5: Determine the area corresponding to the target sensor as the target area where anomalies exist.

[0065] In an embodiment of the present invention, the aforementioned linkage threshold may include multiple associated thresholds, wherein the multiple associated thresholds may correspond to different values.

[0066] For example, in an embodiment of the present invention, assuming that the above-mentioned linkage threshold includes threshold 1 and threshold 2, and the above-mentioned longitudinal wave parameter sequence includes parameter 1, parameter 2, parameter 3, parameter 4, parameter 5, and parameter 6, then assuming that parameter 2 exceeds threshold 1, it is necessary to further determine whether parameter 1 and parameter 3 exceed threshold 2. If both parameter 1 and parameter 3 exceed threshold 2, then the above-mentioned abnormal parameters are parameter 1, parameter 2, and parameter 3; if neither parameter 1 nor parameter 3 exceeds threshold 2, then the above-mentioned abnormal parameter is parameter 2; if parameter 1 exceeds threshold 2 and parameter 3 does not exceed threshold 2, then the above-mentioned abnormal parameters are parameter 1 and parameter 2; if parameter 1 does not exceed threshold 2 and parameter 3 exceeds threshold 2, then the above-mentioned abnormal parameters are parameter 2 and parameter 3.

[0067] Step 104: Send a lockout command to the devices to be controlled within the target area to lock the devices to be controlled.

[0068] In an embodiment of the present invention, after determining the target area range through the above steps, a locking command can be generated and sent to the device to be controlled within the target area range to lock the device to be controlled.

[0069] It should be noted that, in the embodiments of the present invention, by utilizing the time difference between the arrival of P-waves and S-waves in seismic waves, after the arrival of the P-waves, a rapid judgment is made on whether a rockburst has occurred based on preset rules and the P-wave parameter sequence. Thus, before the arrival of the more destructive S-waves, a blocking signal is sent to the equipment around the rockburst location, cutting off power supply and stopping the operation of mechanical equipment, thereby improving the real-time performance of the blocking and effectively reducing the possibility of secondary disasters being induced at the site after a rockburst occurs. This plays a positive role in promoting the prevention and control of rockburst disasters and has significant technical, economic, and safety benefits.

[0070] The electrical equipment control method, device, and storage medium provided by this invention acquire measurement parameters collected by at least one vibration sensor; process the collected measurement parameters to obtain a longitudinal wave parameter sequence corresponding to the measurement parameters; determine the target area range where anomalies exist based on the longitudinal wave parameter sequence and according to preset rules; and send a lockout command to the controlled equipment within the target area to lock the controlled equipment. Therefore, this invention can quickly determine whether a rockburst has occurred based on preset rules and the longitudinal wave parameter sequence, thereby sending a lockout signal to equipment around the rockburst location before the arrival of the more destructive transverse wave, cutting off power supply, and stopping mechanical equipment operation, improving the real-time performance of the lockout. This effectively reduces the possibility of secondary disasters occurring at the site after a rockburst, playing a positive role in promoting the prevention and control of rockburst disasters, and has significant technical, economic, and safety benefits.
