Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a method, device, equipment and medium for evaluating the health of power communication equipment. Background Art

[0002] In the information management of modern power systems, power communication equipment plays an indispensable role and gradually develops towards efficiency, intelligence and cleanliness. With the growing demand for data processing and real-time communication in the power industry, the stability and reliability of power communication equipment have become the key to ensuring the efficient operation of the power system. However, what follows is the increasing complexity and automation of equipment; once the equipment fails, the large amount of manpower and material expenditures generated lead to the continuous increase in equipment maintenance costs, which has become an important expense for power companies. This not only increases the operation and maintenance costs, but also poses a potential risk to the stable operation of the power system. Therefore, maintenance activities play a fundamental role in the management of power communication equipment. As a tangible asset of the power company, power communication equipment accounts for a considerable proportion of the company's total assets, and the quality of the equipment will directly affect the company's economic benefits. According to actual investigations, the company's own large scale, high proportion of total equipment value, and complex management model make management difficult. The health management of equipment withdrawal for complex equipment is an important basis for realizing the intelligent transformation of modern production.

[0003] In the power system, the widespread application of information equipment covers multiple links such as data collection, transmission, processing and control. With the accumulation of equipment operation time, the failure rate of aging equipment gradually increases, and the impact on system stability and safety becomes more significant. In the traditional operation and maintenance management of power communication equipment, there are problems such as monitoring is more important than analysis, and post-processing is more important than prevention. The root cause of these problems lies in the lack of an effective equipment health status assessment mechanism. At present, the health status information of equipment is scattered in various systems, such as asset management systems, fault management systems, etc., and there is a lack of a unified platform to centrally analyze and process these data. This leads to the difficulty of making timely and accurate responses in the actual operation and maintenance process, even in the face of obvious signs of equipment aging and potential failure risks. Therefore, establishing a comprehensive health evaluation system for power communication equipment is of great significance to improving the scientific nature of equipment evacuation standards and ensuring the safe and stable operation of communication systems.

[0004] Fault prediction and health management (PHM) technology provides a new approach to solving the above problems. This technology uses advanced data analysis and machine learning algorithms to achieve real-time monitoring and accurate prediction of equipment health status by comprehensively utilizing information such as equipment operation data, historical maintenance records, and environmental factors. However, although PHM technology is relatively mature in industries such as aerospace and automobile manufacturing, its application in the field of power communications, especially for information equipment in power systems, is still in its infancy. Faced with the special needs and complex environment of power communication networks, how to develop applicable PHM methods and evaluation models based on the characteristics of power communication equipment has become a key technical issue that needs to be solved urgently.

[0005] The status evaluation and equipment health management of the power information and communication system require a comprehensive analysis from multiple dimensions such as the equipment's operating environment, historical performance data, and maintenance records. The traditional equipment maintenance model lacks details and comprehensiveness in the formulation of evacuation standards, and the rules are not clearly defined, resulting in untimely evacuation. There are no special standards to scientifically evaluate the health status of equipment, making it difficult to meet the strict requirements of modern power systems for high reliability and low failure rates. In addition, with the development of power systems towards intelligence and automation, the types and functions of power communication equipment are becoming increasingly complex, which has also brought new challenges to the equipment's evacuation standards and health management; it is necessary to evaluate the health of power communication equipment, conduct health management, and evacuate in advance to avoid communication interruptions caused by power communication equipment failures. Summary of the invention

[0015] If 2 or more of the 7 key indicators are unqualified, the evaluation will fail; the health evaluation result of the power communication equipment will be scrapped;

[0016] Among the 7 categories of key indicators, if there is a category 0 or 1 unqualified, the evaluation passes, and the comprehensive indicator results are used to calculate the health evaluation results of the power communication equipment.

[0017] The present invention is further improved in that: in the step of determining the key indicators and comprehensive indicators of the power communication equipment, the comprehensive indicators include four dimensions: reliability, maintainability, economy, and availability.

[0018] The present invention is further improved in that: the total score of the comprehensive index is 100 points; wherein the scores of reliability, maintainability, economy and availability account for 45:20:15:30 respectively.

[0019] The present invention is further improved in that the sum of the evaluation scores of reliability, maintainability, economy and availability is used as the health evaluation result of the power communication equipment; if the health evaluation result of the power communication equipment is ≥ 60 points, the evaluation is passed and the power communication equipment can continue to be used; if the health evaluation result of the power communication equipment is < 60 points, the evaluation is failed and the power communication equipment is scrapped.

If the evaluation fails, the health evaluation result of the power communication equipment is scrapped; if the evaluation passes, the comprehensive indicator results are used to calculate the health evaluation result of the power communication equipment.

[0025] The present invention is further improved in that: in the step of determining the key indicators and comprehensive indicators of the power communication equipment, the key indicators include seven categories: years of operation, product support period, residual value rate of fixed assets, equipment status, design and manufacturing defects, equipment security vulnerabilities and technical system; the comprehensive indicators include four dimensions: reliability, maintainability, economy and availability.

The present invention ensures the comprehensiveness and objectivity of the evaluation process by rigorously designing an indicator system for the evacuation standard. The scoring weights of different standards have different emphases, and some key indicators are provided with a veto power, which can directly determine the scrapping of the equipment. In addition, in the health evaluation, the reliability index accounts for the largest proportion, ensuring its important position in the overall evaluation. By deeply analyzing the operation status of the equipment and using statistical and time series analysis methods, the method improves the scientificity and systematicity of the evaluation, solves the problems of insufficient timeliness and low accuracy in the equipment status evaluation of the prior art, and provides strong technical support for the stable operation and efficient management of the power communication network.

In the past, there were no clear definition standards and evaluation indicators. The current method can achieve accurate evaluation based on data. Operation and maintenance personnel can make targeted maintenance decisions through rigorous evacuation standards and health evaluation systems. Through hierarchical and multi-dimensional health evaluation models, potential risk points can be quickly identified and early warnings can be given in time, thereby avoiding large-scale equipment failures and communication network interruptions. The overall operating efficiency and stability of the equipment are significantly improved. Through the method of the present invention, the equipment status can be more accurately evaluated, the maintenance strategy can be optimized in a data-driven manner, and the actual operation and maintenance work can be guided by a scientific evaluation system. In the case of limited resources, the method can be used to improve the efficiency of resource utilization and perform equipment maintenance more economically and efficiently, which can significantly reduce operating costs, solve problems in a timely manner before the risk of failure occurs, greatly improve the reliability of the equipment, and reduce power supply interruption events caused by equipment failures.

In addition, the method also provides the ability to dynamically adjust maintenance strategies, which facilitates operation and maintenance personnel to make timely and accurate decisions based on actual conditions, thereby improving the efficiency and effectiveness of equipment management while ensuring the stable operation of the power system.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0037] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0038] In order to meet the challenges of health evaluation of power communication equipment, it is necessary to build a health evaluation framework based on the evacuation standard. The framework should have the following characteristics: First, the indicator design of the evacuation standard should be rigorous, covering all key performance indicators of the equipment to ensure the scientificity and objectivity of the evaluation process; second, the scoring weight of each indicator should be focused, and some key indicators should have a veto power so that the equipment can be directly judged as scrapped under certain circumstances; finally, in the health evaluation indicators, the reliability part should occupy the largest proportion for different equipment to ensure that it has the most important position in the overall evaluation. Through such a design, a scientific and accurate basis can be provided for the operation and maintenance decision of the equipment, and the operation efficiency and safety of the power system can be improved.

[0039] In the process of building a health evaluation system for power communication equipment, the main challenges faced include the complexity of equipment in many aspects and technical difficulties. Formulating a rigorous standard indicator system for evacuation is a key difficulty. There are many types of power communication equipment with different performance indicators. How to scientifically select and weigh various indicators to ensure that they can fully reflect the health status of the equipment is a complex task. Secondly, the scoring weights of different standards need to be carefully designed to ensure the accuracy and reliability of the evaluation results. In particular, some key indicators need to be set with the highest level of weight, which requires a high degree of professionalism and accuracy in the selection and threshold setting of indicators. In addition, in the health evaluation indicators, the importance of the reliability part for different equipment needs to be emphasized, which not only involves in-depth analysis of equipment operation data, but also requires a comprehensive evaluation based on the historical performance and maintenance records of the equipment. In the face of these challenges, it is necessary to conduct in-depth research on data acquisition, processing and analysis technologies to ensure that effective feature information can be extracted from a large amount of operation data, and to convert this information into equipment health indicators by building a scientific health assessment model. Finally, based on these indicators, combined with the operation requirements and maintenance strategies of the power system, scientific and accurate support is provided for the operation and maintenance decisions of the equipment.

[0040] By implementing the above-mentioned power communication equipment health evaluation method, potential equipment failure risks can be discovered in advance, sudden equipment failures can be prevented, and maintenance plans and resource allocation can be optimized according to the actual health status of the equipment to improve maintenance efficiency and equipment utilization. Systematic equipment health management helps to extend the service life of equipment and reduce the operation and maintenance costs of the entire power system, which is of great significance for ensuring the safe and stable operation of the power system and improving the reliability of power supply.

[0041] The health evaluation of power communication equipment has a wide range of applications, including optical transmission equipment, communication optical cables, data power communication equipment, IMS administrative switching network equipment, dispatching switching equipment, terminal access network equipment, microwave equipment, carrier equipment, communication power supply, communication dynamic environment monitoring equipment, video and telephone conferencing equipment, clock synchronization equipment, communication network management equipment, mobile emergency power communication equipment, communication test instruments, etc.

[0042] See also Figure 1 As shown, an embodiment of the present invention provides a method for evaluating the health of power communication equipment, which specifically includes:

[0043] The initial score for the technical appraisal of the health of power communication equipment is set at 100 points, and the appraisal work is carried out in two ways: key indicator appraisal and comprehensive indicator appraisal. The appraisal requirements are as follows:

[0044] a) First, key indicators are used for identification. If two or more key indicators fail to meet the standards, the equipment identification result will be 0 points, and the equipment identification conclusion will be scrapped.

[0045] b) If the equipment does not meet the requirements for the identification of key indicators, a comprehensive indicator identification will be used. A deduction mechanism will be adopted during the identification process. The final cumulative score of all items will be used as the equipment score, and the final conclusion of the health evaluation of the power communication equipment will be made based on the score.

[0046] In a specific implementation, the key indicators include seven categories: years of operation, product support period, fixed asset residual value rate, equipment status, design and manufacturing defects, equipment security vulnerabilities and technical system.

[0047] In a specific implementation, the service life has different measurement standards according to different equipment, for example, according to the longest service life recommended by the manufacturer, if it exceeds the longest service life, it will be eliminated; if the product support period is more than 3 years (including 3 years) after the original manufacturer stops the software and hardware service, it will be eliminated; if the residual value of fixed assets is ≤5% provided by the applicant, the equipment status is that the original manufacturer, the insured manufacturer or the user department provides supporting materials to show that the equipment is no longer usable and cannot be repaired, it will be eliminated; if there are design and manufacturing defects, the equipment has design and manufacturing defects announced by the manufacturer, design and manufacturing defects found in operation, or family defects, and cannot be updated or corrected, it will be eliminated. Equipment security vulnerabilities are the design and manufacturing defects announced by the manufacturer, design and manufacturing defects found in operation, or family defects, and cannot be updated or corrected, it will be eliminated. Technical system is the design and manufacturing defects announced by the manufacturer, design and manufacturing defects found in operation, or family defects, and cannot be updated or corrected, it will be eliminated. The above key indicators need to provide different materials for evidence according to different indicators, and will be scrapped after verification.

[0048] In a specific implementation, if two or more of the seven key indicators are unqualified, the health evaluation score of the power communication equipment is 0, and the equipment appraisal conclusion is scrapped; otherwise, the comprehensive indicators appraise the health evaluation score of the power communication equipment.

[0049] After the key indicators are reviewed, comprehensive indicators are identified. Comprehensive indicators are used to identify the above equipment types. Each equipment type is evaluated from four dimensions: reliability, maintainability, economy, and availability. Different reference indicators and weight levels are set for different dimensions for comprehensive evaluation. Finally, the health evaluation algorithm is called for calculation, sorting, and screening. By combining the needs and maintenance strategies for the retirement and scrapping of power communication equipment, help and support are provided for the maintenance decision of power communication equipment. The following is a detailed description of the evaluation methods and strategies for the above four dimensions:

[0050] 1) Reliability

[0051] Reliability is one of the largest links in the health evaluation of power communication equipment. Since the initial score is set to 100 points, a deduction mechanism is adopted during the appraisal process. The final cumulative score of all items is used as the equipment score. The final appraisal conclusion is made according to the score. Therefore, the scoring weight of the reliability index is set to the highest weight. The reliability assessment is mainly divided into the following steps, as shown below:

[0052] 1.1) Real-time collection and organization of data

[0053] Collecting relevant data during the use of power communication equipment is the basis for reliability calculation. Data collection includes the years of equipment operation, accumulated defects, component status, failure rate in the past year, and design and manufacturing defects announced by the manufacturer. The main process is: first determine the needs and clarify the type of data to be collected. Then, according to the distribution of equipment and the importance of business, select appropriate data collection points to ensure comprehensive coverage of data for core business equipment and non-core business equipment. At the same time, create standardized data collection forms to ensure the consistency and standardization of data records. Finally, through sensors, data recorders and other tools, collect equipment operation data in real time according to established standards to ensure the accuracy and timeliness of the data.

[0054] 1.2) Preliminary processing and classification of data

[0055] The collected data needs to be processed and classified for subsequent analysis. Different types of equipment (core business equipment and non-core business equipment) need to be processed separately. The processing and analysis of different indicators are as follows:

[0056] 1.2.1) Years of operation: Calculate the years from the actual date of commissioning of the equipment to the date of application for appraisal, and make a preliminary score based on the set scoring criteria.

[0057] 1.2.2) Cumulative defects: Collect defect records of core business equipment and non-core business equipment, classify and sort out emergency defects, serious defects and general defects, and score them respectively.

[0058] 1.2.3) Component status: record the current fault status of equipment components, distinguish between main components and auxiliary components, and score according to the set deduction standards.

[0059] 1.2.4) Failure rate in the most recent year: Calculate the failure rate in the most recent year and score according to the set failure rate range.

[0060] 1.2.5) Design and manufacturing defects announced by manufacturers: Collect and confirm the design and manufacturing defect information announced by manufacturers, and deduct points according to their severity.

[0061] In a specific implementation, taking data power communication equipment as an example, the appraisal items are divided into reliability, maintainability, economy, and availability, with the score ratios of 45:20:15:30 respectively. The appraisal items are respectively 10 points for years of operation, 10 points for cumulative defects, 10 points for component status, 10 points for failure rate in the most recent year, and 5 points for design and manufacturing defects announced by the manufacturer. The equipment years of operation are from the actual date of operation to the date of application for appraisal. The deduction standard is ≥8 years of equipment operation, -10 points, 2.5 years≤equipment operation<8 years, -5 points; the sources of defects in the cumulative defects include but are not limited to defect orders, defect reports, operation records, maintenance tickets and offline maintenance records, emergency repair work orders, etc. The deduction standard is -10 points when the IMS core equipment has a fault that affects the normal use of the business and cannot be repaired. If the IMS core equipment has an emergency defect but does not affect the normal use of the business, it needs to be handled urgently: each time the emergency defect occurs, -5 points; the same type of emergency defect occurs twice, -10 points. The main components that affect the operation of the equipment include memory, main control board, and business board. The redundant auxiliary components that do not affect the operation of the equipment include equipment power supply, fan, and port. The deduction standard is the current fault of the component. If one main component fails, 5 points will be deducted, and if one auxiliary component fails, 2 points will be deducted. The deduction will be made until all the points are reduced. The failure rate in the last year refers to the number of failures in the last year / total number of failures (except for no historical failures). The deduction standard is based on the failure rate. If the failure rate in the last year is ≥30%, -10 points, if the failure rate in the last year is ≥20%, -5 points, and if the failure rate in the last year is ≥10%, -1 point. The design and manufacturing defects announced by the manufacturer are based on the manufacturer's announcement or the use department to provide supporting materials. The deduction standard is if the equipment has family defects that have been announced or disclosed to the public and cannot be solved, -5 points. It can be obtained that the reliability index score accounts for the largest proportion, and different standards have different scoring standards.

[0062] 2) Maintainability

[0063] In the health evaluation of power communication equipment, maintainability is a key indicator, which reflects the maintenance cost and frequency required by the equipment during actual use. In order to scientifically and systematically evaluate the maintainability of power communication equipment, the following rules will be followed for statistical and calculation processes. First, the product support period is one of the key factors in evaluating the maintainability of equipment. It is necessary to confirm the period of software and hardware support provided by the manufacturer for the equipment, including the end date of software and hardware support, support content, etc. Verify the accuracy and completeness of the product support period by confirming with the manufacturer or consulting official documents. And record the verified product support period information as a basis for subsequent evaluation; secondly, it is necessary to evaluate the repeated maintenance situation because it reflects the frequency of the same fault occurring during the operation of the equipment. Frequent repeated maintenance not only increases maintenance costs, but may also affect the stability of the equipment. In actual statistics, the maintenance records of the equipment are first analyzed to find out the situations where the same fault occurs twice or more in a year. Then, according to the maintenance records, the number of repeated maintenance of each device is counted, and classified and counted by equipment category. The next step is to score according to the standard according to the number of maintenance times. Finally, it is necessary to evaluate the support of original spare parts, and it is necessary to confirm whether the manufacturer still provides original spare parts for equipment maintenance. This assessment item requires the collection of spare parts support information provided by the manufacturer, including spare parts types and supply periods. The accuracy and completeness of the spare parts support information must be verified by confirming with the manufacturer or reviewing official documents. The verified spare parts support information will then be recorded as the basis for subsequent assessments. The statistical indicators of the above support conditions will be combined to conduct a comprehensive and systematic assessment of the maintainability of power communication equipment. The scores of each dimension are added together to obtain the maintainability score of each device. The higher the score, the better the maintainability of the equipment. Conversely, a lower score means that there are more problems with the equipment during maintenance.

[0064] 3) Economical

[0065] In the health evaluation of power communication equipment, the economic calculation method includes data collection and collation, calculation of the residual value rate of fixed assets and calculation of the proportion of maintenance costs. The first step is to collect data such as equipment purchase cost, accumulated depreciation, current market value and maintenance cost; the second step is to calculate the residual value rate of fixed assets and the proportion of maintenance costs of the equipment, and score them according to the scoring criteria. By combining these scores, the economic efficiency of the equipment can be comprehensively evaluated, providing a scientific basis for the purchase, update and maintenance of the equipment, optimizing resource allocation and improving management efficiency.

[0066] 4) Availability

[0067] Availability uses different calculation methods for different indicators of power communication equipment, and evaluates the functional support of equipment through actual equipment testing, including wavelength division multiplexing, external optical amplifier equipment, optical cables, routers, switches, core network equipment, access equipment, equipment configuration, equipment interface, ONU equipment, RRU equipment, OLT equipment, etc. At the same time, the sub-situations and sub-conditions of the above equipment are refined, and the equipment availability score is calculated comprehensively by testing and scoring each function of the equipment one by one, so as to comprehensively evaluate the performance and adaptability of the equipment in the actual operating environment. This process ensures that the selection and deployment of equipment are more scientific and effective, and provides a reliable basis for the efficient and stable operation of the communication network.

[0068] During the long-term operation of a dispatching and switching device of a certain power company, the equipment gradually aged and broke down frequently. In order to ensure the stability and safety of the system, a technical appraisal of the equipment was conducted for decommissioning and scrapping. First, the key indicators were appraised. The equipment has been in operation for 6 years, which does not exceed the standard of 8 years, so no points were deducted. The manufacturer has stopped supporting the software and hardware of the equipment for 2 years, which does not meet the 3-year elimination standard. The supporting materials provided by the applicant show that the residual value rate of fixed assets is 6%, which is slightly higher than the standard of 5%. Although the equipment is old, it can still operate normally. Therefore, the equipment was not judged as scrapped in the key indicator appraisal.

[0069] Next, a comprehensive indicator appraisal was conducted to comprehensively evaluate the health of the equipment. First, the reliability of the equipment was evaluated. The equipment had two first-level defects in the past year, which was deducted by 10 points and should be directly offline. The failure rate in the past year was 25%, and another 5 points were deducted. Among the main components, the memory and the main control board both failed, and 5 points were deducted for each, totaling 10 points. Among the design and manufacturing defects announced by the manufacturer, the equipment had a family defect that had been announced and could not be solved, which was deducted by 5 points. In terms of maintainability, the product support period of the equipment has expired, which was deducted by 10 points. The equipment had four repeated repairs in the past year, which was deducted by 5 points. There is currently no maintenance, which was deducted by 5 points. In terms of economy, the residual value rate of fixed assets of the equipment is 6%, which was deducted by 5 points. The maintenance cost ratio exceeds 1, which was deducted by 5 points. In terms of availability, the equipment configuration does not meet the requirements of DL / T 795-2016 5.1.2, which was deducted by 4 points.

[0070] Based on the above evaluation results, the total deduction score is 59 points, and the power communication equipment health evaluation score is 41 points, which is less than 60 points. It does not meet the requirements and should be retired and scrapped; the power communication equipment performs poorly in multiple important indicators, and also meets the situation where the same type of emergency defects occur more than twice in the instrumentation and meter and are directly offline. Although it was not immediately judged as scrapped in the key indicator appraisal, the comprehensive indicator appraisal results show that the equipment is no longer suitable for continued use and should be retired and scrapped.

[0071] By predicting and identifying faulty equipment through the method of the present invention, problems can be discovered and solved in time before the fault is fully exposed, and equipment replacement and repair decisions can be made in advance. This not only greatly improves the safety and stability of equipment operation, but also significantly improves the reliability and effectiveness of system operation, providing a solid guarantee for production and use safety.

[0072] See also Figure 2 As shown, an embodiment of the present invention provides a device for evaluating the health of power communication equipment, including:

[0073] A determination module, used to determine the key indicators and comprehensive indicators of the power communication equipment;

[0074] An acquisition module, used to acquire the operating status data of the power communication equipment;

[0075] A calculation module, used to obtain key indicator results and comprehensive indicator results according to the operating status data of the power communication equipment;

[0076] The evaluation module is used to evaluate the health of power communication equipment based on the key indicator results. If the evaluation fails, the health evaluation result of the power communication equipment is scrapped; if the evaluation passes, the comprehensive indicator results are used to calculate the health evaluation result of the power communication equipment.

[0077] In a specific implementation, in the step of determining the key indicators and comprehensive indicators of the power communication equipment, the key indicators include seven categories: years of operation, product support period, residual value rate of fixed assets, equipment status, design and manufacturing defects, equipment security vulnerabilities and technical system; the comprehensive indicators include four dimensions: reliability, maintainability, economy and availability.
