Description

Technical Field

[0001] The present invention belongs to the technical field of special equipment management, and in particular relates to a digital dynamic management method and system for special equipment. Background Art

[0002] The patent with publication number CN118798860A discloses a special equipment detection technology management system and method, including an information management module for managing user and equipment information, a task detection module for analyzing and deploying tasks, a detection management module for optimizing detection processes and methods and updating special equipment detection criteria, a compliance management module for managing and storing inspection reports and updating inspection criteria, a safety warning module for analyzing and monitoring the safety of special equipment detection, and a report statistics module for generating special equipment inspection reports and analyzing inspection results, thereby realizing the automation and intelligence of special equipment detection result evaluation and analysis.

[0003] For special equipment, how to achieve digital dynamic management of real-time operations, especially how to avoid operational errors due to fatigue when personnel operate special equipment, thereby posing safety hazards, while taking into account the monitoring of key operations rather than monitoring every step, is a difficult problem. Based on this, a solution is provided. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art;

[0005] To this end, the present invention proposes a digital dynamic management method for special equipment, which specifically includes:

[0006] If any operation of the user on the target device directly causes a fault, and the fault results in casualties, the operation is considered a high-order operation;

[0007] Based on the number of operations on the target device that appear in the fault record and are marked as direct operations and associated operations, as well as the resulting fault losses, the operations are classified into high-order operations, medium-order operations, and low-order operations according to the sequence value representing the criticality of the operations from high to low.

[0008] The operation being performed by the user is represented as the predecessor operation, the next operation of the predecessor operation is represented as the successor operation, and the previous operation of the predecessor operation is represented as the predecessor operation;

[0009] Based on whether the succession operation is a high-sequence operation, a normal high-sequence operation, a normal medium-sequence operation, or a normal low-sequence operation, and in combination with the fatigue level during the preceding operation, the preceding operation, and the succession operation, the user's subsequent instructions for operating the target device are intercepted.

[0010] Furthermore, casualties are obtained through fault records, which include loss values indicating economic losses caused by the corresponding fault. If casualties occur, the fault loss will be labeled with casualties.

[0011] Furthermore, the fault record also includes a direct operation indicating the operation that directly causes the fault, and an associated operation indicating the last operation before the fault occurs.

[0012] Furthermore, the sequence value is obtained by multiplying the direct value, the associated value, and the loss value by the assigned weights and then adding them together;

[0013] The direct value is used to indicate the number of times the operation was marked as a direct operation;

[0014] The association value is used to indicate the number of times the operation is marked as an association operation;

[0015] The loss value is used to represent the sum of all failure losses corresponding to the operation appearing in the failure record.

[0016] Furthermore, fatigue is obtained by comparing the real-time operation duration of any operation with a reasonable operation range that represents the reasonable operation duration when the user performs the operation normally. When the real-time operation duration is greater than the reasonable operation range, it indicates that the user is fatigued.

[0017] Furthermore, when the user's successive operation is a high-sequence operation or a normal-sequence high-operation, if the user becomes fatigued while performing the leading operation or the successive operation, the user's subsequent instructions to operate the target device are intercepted.

[0018] Furthermore, when the user's successive operation belongs to an operation in a normal sequence, if the user becomes fatigued when performing both the leading operation and the successive operation, the user's subsequent instructions to operate the target device are intercepted.

[0019] Furthermore, when the user's successive operation belongs to a normal low-sequence operation, if the user becomes fatigued while performing the pre-leading operation, the leading operation, and the successive operation, the user's subsequent instructions to operate the target device are intercepted.

[0020] Furthermore, the user's fatigue level is also determined by the ratio of the user's real-time blinking frequency when the user's pupils constrict to the initial blinking frequency representing the user's normal state:

[0021] When the user's takeover operation is any of the high-order operation and the normal high-order operation, if the real-time blinking frequency is not less than X2 times the initial blinking frequency, the user's takeover operation is automatically stopped; X2 is a preset value and is greater than 1;

[0022] If the takeover operation is in the normal sequence, and the real-time blink frequency is not less than 1.2 times the initial blink frequency multiplied by X2, the user's takeover operation will be automatically stopped;

[0023] When the replacement operation is a normal low operation, if the real-time blink frequency is not less than 1.4 times of the initial blink frequency multiplied by X2, the replacement operation of the user is automatically stopped.

[0024] Furthermore, the system adopts the foregoing method to realize the digital dynamic management of characteristic devices.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] In this application, operations are sequentially divided into normal high operations, normal medium operations, and normal low operations according to the sequence values representing the criticality of operations from high to low; the criticality of each operation of the user can be determined, and the critical operation steps can be selected;

[0027] Then, by virtue of the replacement operation belonging to any one of high-order operations, normal high operations, normal medium operations, and normal low operations, combined with the fatigue levels during the pilot pre-operation, pilot operation, and replacement operation, the instruction for the user to operate the target device subsequently is stopped, which can analyze the state of the user performing key-step operations and prohibit the operation of personnel when the state is not good, avoiding potential safety hazards.

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 , this application provides a method for digital dynamic management of special equipment;

[0031] As Embodiment 1 of this application, the method specifically includes the following steps in this embodiment:

[0032] Step 1: First, mark the special equipment to be analyzed as the target equipment, and then obtain all the fault records of the target equipment in the past three years. The fault records include fault losses, direct operations, and associated operations. Here, the fault loss refers to how much economic loss is brought by the corresponding equipment fault. If the corresponding fault causes casualties, the economic loss will be labeled with casualties for easy system identification; the direct operation means that the fault is caused by an incorrect operation step or a failure to carefully check the inspection step, and the associated operation means the last operation on the target equipment by the operator of the target equipment before the fault occurs;

[0033] Step 2: Then obtain all the operations that need to be performed on the corresponding target equipment and mark them as sequential operations;

[0034] Obtain the sequential operations that are marked as direct operations and whose corresponding fault records marked as direct operations are labeled with casualties, and mark them as high-order operations;

[0035] The remaining are marked as normal-order operations;

[0036] Perform a split process on the normal-order operations. The specific split method is as follows:

[0037] Obtain the number of times all normal-order operations are marked as direct operations and associated operations, and after removing the dimension, mark them as direct values and associated values in sequence;

[0038] At the same time, obtain the fault losses existing in the fault records where the corresponding normal-order operations are marked as the corresponding associated operations or direct operations. After adding up all the total fault losses, mark the pure numerical value after removing the dimension of this value as the loss value;

[0039] Obtain the direct values, associated values, and loss values of all normal-order operations, and use the formula to calculate the sequence values of all normal-order operations. The specific calculation formula is:

[0040] Sequence value = 0.42 * direct value + 0.33 * associated value + 0.25 * loss value;

[0041] In the formula, 0.42, 0.33, and 0.25 are all preset weight values used to highlight the different roles of different elements;

[0042] Then, according to the sequence values, divide the top 25% of the normal-order operations into normal-order high operations, divide the last 35% of the sorted operations into normal-order low operations, and mark the remaining as normal-order medium operations;

[0043] Form an operation sequence list with the obtained high-order operations, normal-order high operations, normal-order medium operations, and normal-order low operations;

[0044] Step 3: Monitor the fatigue level of the personnel. The specific method is as follows:

[0045] Obtain the duration of each use by the operator of the corresponding target device during different sequence operations in the recent period, and mark it as the operation duration. For each sequence operation, there are several operation durations for the same operator.

[0046] Select any one sequence operation, obtain all the operation durations, mark them as Ci, where i = 1,..., n, indicating that there are n operation durations and the corresponding sequence operation is executed n times. Obtain the mean value P of Ci, and then calculate the deviation value W of Ci using the formula. The specific calculation formula is as follows:

[0047]

[0048] When the value of W exceeds X1 (X1 is a preset value), automatically enter the numerical screening process. The specific method is as follows:

[0049] Sort Ci in descending order according to |Ci - P|, then select Ci in sequence. Each time a Ci is selected, delete it, calculate the W value of the remaining Ci. If it still exceeds X1, then continue to select the next Ci in sequence and delete it until the W value of the remaining Ci does not exceed X1. Mark the range from the minimum value to the maximum value of the remaining Ci as the reasonable operation range.

[0050] Then perform the same operation on the remaining sequence operations to obtain the reasonable operation ranges of all sequence operations, and mark the sequence operations and their corresponding reasonable operation ranges as the sequence operation range table.

[0051] Step 4: Monitor the real-time duration of the personnel during sequence operations, and obtain the real-time operation duration of each sequence operation when the personnel operate the target device.

[0052] Step 5: Perform operation verification based on the real-time operation duration and the operation sequence table. The specific method of operation verification is as follows:

[0053] Monitor the user's real-time operation. When the next operation is a high-order operation or a normal high-order operation, mark this operation as the leading operation, obtain the duration of the user during the leading operation and mark it as the leading duration. At the same time, obtain the reasonable range corresponding to the leading operation from the sequence operation range table and mark it as the leading range.

[0054] After obtaining the leading duration, if the leading duration is greater than the maximum value of the leading range, the subsequent operations will be automatically stopped. At this time, it indicates that the user's operation is deviated, which may be due to fatigue or status. The subsequent operations will be stopped, and the slow shutdown operation will be automatically executed. The slow shutdown operation refers to stopping the target device or stopping the startup of the corresponding target device in the most appropriate way;

[0055] If the leading duration is not greater than the leading range (here, not greater than means that the leading duration is within the leading range or less than the minimum value of the leading range), the corresponding next operation will be obtained and marked as the replacement operation, which is the high-order operation or the normal-order high operation here. The operation duration of the replacement operation will be obtained. If the operation duration of the replacement operation is still greater than the maximum value of the corresponding reasonable operation range, the instruction of the corresponding replacement operation will be automatically intercepted, and the slow shutdown operation will be performed at the same time;

[0056] If the replacement operation is a normal-order middle operation, at this time, it is necessary that the leading duration is greater than the leading range and the operation duration of the replacement operation is still greater than the corresponding reasonable operation range. Only then will the instruction of the corresponding replacement operation be intercepted, and the slow shutdown operation will be performed at the same time;

[0057] If the replacement operation is a normal-order low operation, then the operation before the leading operation needs to be obtained and marked as the pre-leading operation. Then the corresponding operation duration will be obtained and marked as the pre-leading duration. At this time, if it is detected that the pre-leading duration, the leading duration, and the operation duration of the replacement operation are all greater than the reasonable range of the corresponding operation, the instruction of the corresponding replacement operation will be intercepted, and the slow shutdown operation will be performed at the same time, otherwise no processing will be done;

[0058] Of course, as Embodiment 2 of the present application, this embodiment is implemented on the basis of Embodiment 1. The difference from Embodiment 1 is that in this embodiment, the fatigue degree in Step 3 is not determined by the operation duration, but by detecting the user's physiological parameters. The specific method is as follows:

[0059] When the user's pupil shrinks, this adopts the existing technology and will not be described in detail. Generally, the pupil can be photographed by a camera with a fixed focal length or position. After determining the pupil edge by using the edge detection method, the initial pupil area will be automatically converted to obtain the normal pupil area of the staff at the beginning of work, and then it will be used as the initial value. Subsequently, the real-time area of the staff's pupil will be obtained. When the real-time area is lower than 85% of the initial value, a pupil shrinkage signal will be automatically generated;

[0060] When the pupil shrinkage signal is generated, the fatigue degree detection will be automatically performed. The specific method of the fatigue degree detection is as follows:

[0061] Mark the first 20% of the entire process of the user's last operation of the target device without fatigue as the initial process, obtain the user's average blink frequency during the initial process, and mark it as the initial blink frequency;

[0062] Then, the real-time blinking frequency of the user when operating the target device in real time at the latest moment is obtained, and the next operation of the user operating the target device is monitored in real time.

[0063] If the next operation, i.e., the succession operation mentioned in Example 1, is any of the high-order operation and the normal-order high-order operation, the most recent blink frequency will be automatically obtained. If it is not less than X2 times the initial blink frequency, where X2 is a preset value and greater than 1, the user will be marked as fatigued, and the succession operation will be automatically stopped, and a slow shutdown operation will be performed. Of course, in general, the value of X1 here is 1.1.

[0064] If the takeover operation is in the normal sequence, the most recent blink frequency will be automatically obtained. If it is not less than 1.2*X2 times the initial blink frequency, the user will be marked as fatigued, and the user's takeover operation will be automatically stopped, and a slow shutdown operation will be performed at the same time;

[0065] If the takeover operation is a normal low-order operation, the most recent blink frequency will be automatically obtained. If it is not less than 1.4*X2 times the initial blink frequency, the user will be marked as fatigued, and the user's takeover operation will be automatically stopped, and a slow shutdown operation will be performed at the same time;

[0066] Of course, as the third embodiment of the present application, this embodiment can integrate the first and second embodiments for implementation.

[0067] Of course, the present application also provides a digital dynamic management system for special equipment, which mainly manages special equipment digitally through the dynamic management methods disclosed in the above three embodiments.

[0068] Some of the data in the above formula are calculated by removing the dimensions and taking their numerical values. The formula is a formula that is closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0069] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
