Description

Technical Field

[0001] The invention relates to the technical field of operation and maintenance alarm, and in particular to an operation and maintenance alarm system of a digital papermaking integrated control system. Background Art

[0002] In the modern papermaking industry, with the rapid development of digital technology, traditional production and operation and maintenance management methods are gradually unable to meet the growing production efficiency and quality requirements. Therefore, the operation and maintenance alarm system of the digital papermaking integrated control system came into being. Its main purpose is to improve the operation and maintenance management level of equipment through intelligent means and ensure the stability and efficiency of the production process.

[0003] Prior art, such as the invention patent application with announcement number CN116149236B, discloses an intelligent monitoring system and method for application operation and maintenance management based on blockchain, including a relevant data acquisition module, an application operation and maintenance early warning index analysis module, an early warning group value analysis module, a threshold determination early warning module and a feedback monitoring module; the relevant data acquisition module is used to obtain relevant data of users' operation of smart devices based on smart applications; the application operation and maintenance early warning index analysis module is used to analyze the application operation and maintenance early warning index of applications associated with smart devices; the early warning group value analysis module is used to extract the application operation and maintenance early warning index of different users who use the same application in the blockchain; the threshold determination early warning module is used to set the early warning group value threshold of applications associated with smart devices; the feedback monitoring module is used to obtain relevant data from users who re-enter the monitoring cycle after the maintenance and management of the smart application is completed, and transfer it to the application operation and maintenance early warning index analysis module.

[0004] In view of the above scheme, the applicant of the present invention has found that the above technology has at least the following technical problems: 1. The prior art operation and maintenance alarm system often relies on fixed thresholds. Once a fault occurs, the reaction speed is slow, resulting in the maintenance personnel failing to take timely measures, which may further expand the fault, thereby causing production downtime and economic losses. At the same time, the arrangement of maintenance personnel often lacks intelligent analysis, which may lead to unreasonable matching of junior and senior maintenance personnel. There is no reasonable allocation based on success rate or experience, resulting in low maintenance efficiency, complex faults cannot be handled in time, and junior maintenance personnel lack necessary supervision and guidance when operating complex equipment, which may lead to operational errors due to lack of experience, increasing safety hazards in the production process and even causing more serious accidents.

[0005] 2. Existing technologies may not be able to effectively collect and analyze historical maintenance data, and lack scientific data support to make operation and maintenance decisions, resulting in blind or unreasonable threshold settings, reducing the effectiveness of operation and maintenance management. The lack of effective maintenance combination analysis may lead to unnecessary participation of senior maintenance personnel in some simple fault handling, wasting human resources and increasing maintenance costs. At the same time, it may not be possible to monitor the maintenance process in real time, resulting in problems of junior maintenance personnel in the maintenance combination not being discovered in time, and being intervened only after a long period of operation, which increases the time for fault handling. In the absence of guidance and training, the business capabilities of junior maintenance personnel cannot grow, which affects the professional level of the entire team and leads to poor maintenance results. Summary of the invention

[0006] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide an operation and maintenance alarm system for a digital papermaking integrated control system.

[0007] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an operation and maintenance alarm system for a digital papermaking integrated control system, including: an operation and maintenance alarm threshold adjustment module: used to obtain maintenance indicators corresponding to each fault type in each maintenance department of the target paper mill in the historical period, the maintenance indicators include the frequency of occurrence, the maintenance time corresponding to each maintenance personnel, and the number of requests for help, so as to determine whether the operation and maintenance warning threshold corresponding to each fault type in each maintenance department needs to be adjusted.

[0008] Maintenance personnel matching analysis module: when a maintenance department receives a maintenance alarm, it matches the junior maintenance personnel with the senior maintenance personnel in the maintenance department, so as to obtain the maintenance combination corresponding to the maintenance alarm in the maintenance department, and notify the maintenance combination in the maintenance department to perform maintenance.

[0009] Maintenance personnel warning module: It is used to evaluate whether junior maintenance personnel can perform actual operations in a maintenance group in a maintenance department before the group performs maintenance. If junior maintenance personnel can perform actual operations in the maintenance group, the junior maintenance personnel actual operation warning will be enabled.

[0010] Preferably, the operation and maintenance alarm threshold adjustment module also includes a maintenance index analysis unit and an operation and maintenance warning threshold adjustment unit.

[0011] The maintenance index analysis unit is used to analyze and obtain the maintenance evaluation coefficient corresponding to each fault type in each maintenance department according to the maintenance index corresponding to each fault type in each maintenance department.

[0012] The operation and maintenance warning threshold adjustment unit is used to adjust the operation and maintenance warning threshold corresponding to a certain fault type in a maintenance department when it is determined that the operation and maintenance warning threshold corresponding to the fault type in the maintenance department needs to be adjusted.

[0013] Preferably, the determination of whether the operation and maintenance warning threshold corresponding to each fault type in each maintenance department needs to be adjusted is specifically carried out as follows: the maintenance assessment coefficient corresponding to each fault type in each maintenance department is compared with the maintenance assessment coefficient corresponding to the set standard fault. If the maintenance assessment coefficient corresponding to a certain fault type in a maintenance department is smaller than the maintenance assessment coefficient corresponding to the set standard fault, then it is determined that the operation and maintenance warning threshold corresponding to the fault type in the maintenance department needs to be adjusted; if the maintenance assessment coefficient corresponding to a certain fault type in a maintenance department is greater than or equal to the maintenance assessment coefficient corresponding to the set standard fault, then it is determined that the operation and maintenance warning threshold corresponding to the fault type in the maintenance department does not need to be adjusted. In this way, it is determined whether the operation and maintenance warning threshold corresponding to each fault type in each maintenance department needs to be adjusted.

[0014] Preferably, when it is determined that the operation and maintenance warning threshold corresponding to a certain fault type in a maintenance department needs to be adjusted, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is adjusted. The specific adjustment process is as follows: A1. When the operation and maintenance warning threshold corresponding to a certain fault type in a maintenance department needs to be adjusted, the maintenance assessment coefficient corresponding to the fault type in the maintenance department and the maintenance assessment coefficient corresponding to the set standard fault are calculated as a difference. If the difference is less than 10, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is reduced by 5%.

[0015] A2. If the difference is between 10 and 15, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is reduced by 10%.

[0016] A3. If the difference is greater than 15, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is reduced by 15%.

[0017] Preferably, when a maintenance department receives a maintenance alarm, the junior maintenance personnel in the maintenance department are matched with the senior maintenance personnel. The specific matching process is as follows: B1. When a maintenance department receives a maintenance alarm, the maintenance alarm platform displays the fault type corresponding to the maintenance alarm.

[0018] B2. Obtain the success rate corresponding to the fault type among the junior maintenance personnel in the maintenance department and the success rate corresponding to the fault type among the senior maintenance personnel in the maintenance department, and sort the junior maintenance personnel in the maintenance department according to the success rate corresponding to the fault type. At the same time, sort the senior maintenance personnel in the maintenance department according to the success rate corresponding to the fault type, and match the junior maintenance personnel with the lowest success rate for the fault type in the maintenance department with the senior maintenance personnel with the highest success rate for the fault type in the maintenance department.

[0019] Preferably, the maintenance personnel warning module further includes a fault data acquisition unit and a fault data analysis unit.

[0020] The fault data acquisition unit is used to acquire the fault data corresponding to the maintenance alarm in the maintenance department, and the fault data includes alarm frequency, maintenance cost and production loss.

[0021] The fault data analysis unit is used to analyze the fault data corresponding to the maintenance alarm in the maintenance department to obtain the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department.

[0022] Preferably, the evaluation of whether junior maintenance personnel can be allowed to perform actual operations in the maintenance combination is performed by the following specific evaluation process: C1. Compare the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department with the fault assessment coefficient corresponding to the set standard maintenance alarm. If the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department is smaller than the fault assessment coefficient corresponding to the set standard maintenance alarm, then it is evaluated that junior maintenance personnel cannot be allowed to perform actual operations in the maintenance combination, and then the senior maintenance personnel in the maintenance combination are allowed to perform actual operations, while the junior maintenance personnel in the maintenance combination observe.

[0023] C2. If the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department is greater than or equal to the fault assessment coefficient corresponding to the set standard maintenance alarm, then it is evaluated that the junior maintenance personnel in the maintenance combination can perform the actual operation, and then the junior maintenance personnel in the maintenance combination can perform the actual operation, while the senior maintenance personnel in the maintenance combination observe.

[0024] Preferably, if junior maintenance personnel are allowed to perform actual operations in the maintenance combination, an early warning for junior maintenance personnel's actual operations is activated. The specific early warning process is as follows: D1. When junior maintenance personnel are allowed to perform actual operations in the maintenance combination, a standard maintenance time corresponding to the maintenance alarm is set. If the maintenance time of the junior maintenance personnel in the maintenance combination exceeds the standard maintenance time corresponding to the maintenance alarm, an early warning prompt is sent. The early warning prompt will be sent to the communication equipment of the junior maintenance personnel and senior maintenance personnel in the maintenance combination.

[0025] D2. If the communication equipment of the junior maintenance personnel and the senior maintenance personnel in the maintenance group receives an early warning, the junior maintenance personnel in the maintenance group stops the actual operation and the senior maintenance personnel in the maintenance group perform the actual operation instead, while the junior maintenance personnel in the maintenance group observes on the side.

[0026] The beneficial effects of the present invention are as follows: 1. In the embodiment of the present invention, the system automatically determines whether it is necessary to adjust the operation and maintenance warning threshold by analyzing the maintenance data in the historical cycle, including the frequency of failures, maintenance duration, and number of requests for help. This dynamic adjustment mechanism can more accurately reflect the actual operation and maintenance situation, avoid premature or late alarms, improve the system's warning accuracy and response efficiency, and provide scientific data support through the analysis of historical maintenance data and fault data, making decisions such as operation and maintenance threshold adjustment and personnel matching more reasonable and accurate. At the same time, this data-driven method also provides an important reference for enterprises to optimize production processes and improve maintenance strategies.

[0027] 2. In the embodiment of the present invention, when the system receives a maintenance alarm, it can intelligently match junior maintenance personnel with senior maintenance personnel based on the success rate of each maintenance personnel. The specific method is to combine junior maintenance personnel with the lowest success rate with senior maintenance personnel with the highest success rate, so as to ensure that when dealing with complex faults, there is both guidance from experienced personnel and training for junior personnel, thereby improving the overall maintenance capabilities of the team. The system can effectively shorten the fault handling time, reduce production downtime, and thus reduce production losses. At the same time, the system's comprehensive analysis of factors such as alarm frequency and maintenance costs also helps to discover potential problems, prevent them in advance, and further reduce maintenance costs.

[0028] 3. In the embodiment of the present invention, the system is designed with a practical operation warning mechanism for junior maintenance personnel, which determines whether junior personnel are allowed to perform actual operations by analyzing fault data and evaluation coefficients. This mechanism can not only ensure that junior personnel can accumulate experience under low-risk conditions, but also effectively prevent production losses caused by improper operation, ensure production safety and maintenance quality. When junior maintenance personnel perform practical operations, the system will conduct real-time monitoring according to the preset standard maintenance time. If the practical operation time exceeds the standard time, the system will send an early warning prompt to enable senior maintenance personnel to intervene in time to avoid the expansion of problems caused by the lack of experience of junior personnel. The intelligent matching and practical operation management functions of the system can not only improve the skill level of junior maintenance personnel, but also improve the collaborative work efficiency and ability to handle complex faults of the entire maintenance team through the guidance and supervision of experienced maintenance personnel.

The maintenance indicators include the frequency of occurrence, the maintenance time and the number of requests for help corresponding to each maintenance personnel, so as to determine whether the operation and maintenance warning threshold corresponding to each fault type in each maintenance department needs to be adjusted.

[0035] It should be noted that fault records are extracted from the maintenance management system, the occurrence time, type and duration of each fault are recorded, all maintenance work orders are collected, detailed information of each maintenance task is recorded, including fault type, maintenance personnel, maintenance duration and completion date, user help records are obtained from the customer service system or technical support system, the frequency of help requests for each fault type is understood, and then the occurrence frequency of each fault type in each maintenance department of the target paper mill in the historical period, the maintenance duration and number of help requests for each maintenance personnel are obtained.

The specific analysis process is as follows: the occurrence frequency corresponding to each fault type in each maintenance department, the maintenance time and the number of requests for help corresponding to each maintenance personnel are recorded as , and ,in, Indicates the number corresponding to each maintenance department. , u is any integer greater than 2, Indicates the number corresponding to each fault type. , n is any integer greater than 2, Indicates the number corresponding to each maintenance personnel. , m is any integer greater than 2, substitute it into the calculation formula: The maintenance assessment coefficient corresponding to each fault type in each maintenance department is obtained ,in, , , They are the standard occurrence frequency of the set faults, the standard maintenance time of the maintenance personnel, and the standard number of requests for help. , , They are the weight factors corresponding to the set fault frequency, the weight factors corresponding to the maintenance time of the maintenance personnel, and the weight factors corresponding to the number of requests for help. Represents a natural constant.

[0040] It should be noted that , , Both are greater than 0 and less than 1.

[0041] It should also be noted that through the summary of a large amount of research data and experimental data, professional institutions and research institutions set the standard frequency of failures, the standard maintenance time for maintenance personnel, and the standard number of requests for help. At the same time, based on the professional knowledge and research basis of experts in the field, they discuss and confirm with industry organizations or professional institutions. Experts set the weight factors corresponding to the frequency of failures, the weight factors corresponding to the maintenance time of maintenance personnel, and the weight factors corresponding to the number of requests for help based on their own experience and knowledge.

[0042] It should be noted again that the standard occurrence frequency, the standard maintenance time corresponding to the maintenance personnel, and the standard number of requests for help are the occurrence frequency threshold, the maintenance time threshold corresponding to the maintenance personnel, and the number of requests for help threshold, respectively. For example, the standard occurrence frequency is 5, the standard maintenance time corresponding to the maintenance personnel is 30, and the standard number of requests for help is 2.

[0043] In a specific embodiment, the determination of whether the operation and maintenance warning threshold corresponding to each fault type in each maintenance department needs to be adjusted is performed as follows: the maintenance assessment coefficient corresponding to each fault type in each maintenance department is compared with the maintenance assessment coefficient corresponding to the set standard fault. If the maintenance assessment coefficient corresponding to a certain fault type in a maintenance department is smaller than the maintenance assessment coefficient corresponding to the set standard fault, then it is determined that the operation and maintenance warning threshold corresponding to the fault type in the maintenance department needs to be adjusted; if the maintenance assessment coefficient corresponding to a certain fault type in a maintenance department is greater than or equal to the maintenance assessment coefficient corresponding to the set standard fault, then it is determined that the operation and maintenance warning threshold corresponding to the fault type in the maintenance department does not need to be adjusted. In this way, it is determined whether the operation and maintenance warning threshold corresponding to each fault type in each maintenance department needs to be adjusted.

[0044] In a specific embodiment, when it is determined that the operation and maintenance warning threshold corresponding to a certain fault type in a maintenance department needs to be adjusted, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is adjusted. The specific adjustment process is as follows: A1. When the operation and maintenance warning threshold corresponding to a certain fault type in a maintenance department needs to be adjusted, the maintenance assessment coefficient corresponding to the fault type in the maintenance department and the maintenance assessment coefficient corresponding to the set standard fault are calculated. If the difference is less than 10, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is reduced by 5%.

[0045] A2. If the difference is between 10 and 15, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is reduced by 10%.

[0046] A3. If the difference is greater than 15, the operation and maintenance warning threshold corresponding to the fault type in the maintenance department is reduced by 15%.

[0047] In the embodiment of the present invention, the system automatically determines whether it is necessary to adjust the operation and maintenance warning threshold by analyzing the maintenance data in the historical cycle, including the frequency of failures, maintenance duration, and number of requests for help. This dynamic adjustment mechanism can more accurately reflect the actual operation and maintenance situation, avoid premature or late alarms, improve the accuracy of the system's warnings and response efficiency, and provide scientific data support through the analysis of historical maintenance data and fault data, making decisions such as operation and maintenance threshold adjustment and personnel matching more reasonable and accurate. At the same time, this data-driven method also provides an important reference for enterprises to optimize production processes and improve maintenance strategies.

[0048] Maintenance personnel matching analysis module: when a maintenance department receives a maintenance alarm, it matches the junior maintenance personnel with the senior maintenance personnel in the maintenance department, so as to obtain the maintenance combination corresponding to the maintenance alarm in the maintenance department, and notify the maintenance combination in the maintenance department to perform maintenance.

[0049] In a specific embodiment, when a maintenance department receives a maintenance alarm, the junior maintenance personnel in the maintenance department are matched with the senior maintenance personnel. The specific matching process is as follows: B1. When a maintenance department receives a maintenance alarm, the maintenance alarm platform displays the fault type corresponding to the maintenance alarm.

[0050] B2. Obtain the success rate corresponding to the fault type among the junior maintenance personnel in the maintenance department and the success rate corresponding to the fault type among the senior maintenance personnel in the maintenance department, and sort the junior maintenance personnel in the maintenance department according to the success rate corresponding to the fault type. At the same time, sort the senior maintenance personnel in the maintenance department according to the success rate corresponding to the fault type, and match the junior maintenance personnel with the lowest success rate for the fault type in the maintenance department with the senior maintenance personnel with the highest success rate for the fault type in the maintenance department.

[0051] In the embodiment of the present invention, when the system receives a maintenance alarm, it can intelligently match junior maintenance personnel with senior maintenance personnel based on the success rate of each maintenance personnel. The specific method is to combine junior maintenance personnel with the lowest success rate with senior maintenance personnel with the highest success rate, ensuring that when dealing with complex faults, there is both guidance from experienced personnel and the training of junior personnel, thereby improving the overall maintenance capabilities of the team. The system can effectively shorten the fault handling time, reduce production downtime, and thus reduce production losses. At the same time, the system's comprehensive analysis of factors such as alarm frequency and maintenance costs also helps to discover potential problems, prevent them in advance, and further reduce maintenance costs.

[0052] Maintenance personnel warning module: It is used to evaluate whether junior maintenance personnel can perform actual operations in a maintenance group in a maintenance department before the group performs maintenance.

[0054] The fault data acquisition unit is used to acquire the fault data corresponding to the maintenance alarm in the maintenance department, and the fault data includes alarm frequency, maintenance cost and production loss.

[0055] It should be noted that the alarm records are extracted from the maintenance management system. The timestamp and fault type of each alarm are recorded, and financial management software, maintenance management system or data analysis tools are used to assist in data collection and analysis to obtain maintenance costs and production losses.

[0056] The fault data analysis unit is used to analyze the fault data corresponding to the maintenance alarm in the maintenance department to obtain the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department.

[0057] In a specific embodiment, the analysis obtains the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department. The specific analysis process is as follows: the alarm frequency, maintenance cost and production loss corresponding to the maintenance alarm in the maintenance department are respectively recorded as , and , substitute into the calculation formula: The fault assessment coefficient corresponding to the maintenance alarm in the maintenance department is obtained. ,in, , , They are the standard alarm frequency, standard maintenance cost, and standard production loss corresponding to the set maintenance alarm. , , They are the weight factor corresponding to the set maintenance alarm frequency, the weight factor corresponding to the maintenance cost, and the weight factor corresponding to the production loss.

[0058] It should be noted that , , Both are greater than 0 and less than 1.

[0059] It should also be noted that through the summary of a large amount of research data and experimental data, the standard alarm frequency, standard maintenance cost, and standard production loss corresponding to the maintenance alarm are set by professional institutions and research institutions. At the same time, based on the professional knowledge and research basis of experts in the field, and discussed and confirmed with industry organizations or professional institutions, the experts set the weight factors corresponding to the alarm frequency of the maintenance alarm, the weight factors corresponding to the maintenance cost, and the weight factors corresponding to the production loss according to their own experience and knowledge.

[0060] It should be noted again that the standard alarm frequency, the standard maintenance cost, and the standard production loss are the alarm frequency threshold, the maintenance cost threshold, and the production loss threshold, respectively. For example, the standard alarm frequency is 5, the standard maintenance cost is 200, and the standard production loss is 300.

[0061] In a specific embodiment, the evaluation of whether the maintenance combination can allow junior maintenance personnel to perform actual operations is performed, and the specific evaluation process is as follows: C1. Compare the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department with the fault assessment coefficient corresponding to the set standard maintenance alarm.

[0062] C2. If the fault assessment coefficient corresponding to the maintenance alarm in the maintenance department is greater than or equal to the fault assessment coefficient corresponding to the set standard maintenance alarm, then it is evaluated that the junior maintenance personnel in the maintenance combination can perform the actual operation, and then the junior maintenance personnel in the maintenance combination can perform the actual operation, while the senior maintenance personnel in the maintenance combination observe.

[0063] In a specific embodiment, if the junior maintenance personnel are allowed to perform actual operations in the maintenance combination, the junior maintenance personnel actual operation warning is activated, and the specific warning process is as follows: D1. When the junior maintenance personnel are allowed to perform actual operations in the maintenance combination, the standard maintenance time corresponding to the maintenance alarm is set. If the maintenance time of the junior maintenance personnel in the maintenance combination exceeds the standard maintenance time corresponding to the maintenance alarm, a warning prompt is sent. The warning prompt will be sent to the communication equipment of the junior maintenance personnel and the senior maintenance personnel in the maintenance combination.

[0065] In the embodiment of the present invention, the system is designed with a practical operation warning mechanism for junior maintenance personnel, which determines whether junior personnel are allowed to perform actual operations by analyzing fault data and evaluation coefficients. This mechanism can not only ensure that junior personnel can accumulate experience under low-risk conditions, but also effectively prevent production losses caused by improper operation, ensure production safety and maintenance quality. When junior maintenance personnel perform practical operations, the system will conduct real-time monitoring according to the preset standard maintenance time.
