Description

Technical Field

[0001] The invention belongs to the technical field of power equipment maintenance, and in particular relates to a comprehensive maintenance method for power communication equipment. Background Art

[0002] The inspection management platform plays a vital role in the operation and maintenance of power equipment. It usually has functions such as task allocation, data collection, status monitoring, hidden danger warning, and report generation. Through such a platform, managers can obtain problems in a timely manner, and at the same time reasonably assign inspection tasks to relevant personnel according to factors such as equipment type and region to ensure that the inspection work is fully covered and efficiently executed. For example, the applicant applied for an invention patent with patent application number CN202311492514.9 last year, "Power Equipment Operation and Maintenance Method Based on Intelligent Inspection Management Platform". In the patent, the intelligent inspection management platform generates corresponding equipment tags based on the equipment identification code of the power equipment, and builds an equipment tag library for storage; secondly, the identity and authority information of the maintenance terminal corresponding to the power equipment is bound to the equipment tag, and a mapping table is built to ensure data security; then, by collecting the historical operation data of the power equipment, a status assessment model is constructed, and the power equipment is evaluated to obtain the status assessment level; then, a maintenance plan is formulated according to the status assessment level, and it is assigned to the corresponding maintenance terminal for execution through the intelligent inspection management platform; finally, the maintenance terminal transmits the maintenance results to the platform through the data encryption protocol for archiving.

[0003] Through such a technical solution, the patent sets thresholds through historical fault data, determines the power equipment to be inspected, improves management and maintenance efficiency, improves equipment reliability, ensures normal operation of equipment and prolongs life, and stabilizes the power system. Query the equipment tag library to obtain equipment information and permission relationship table, determine equipment requirements, improve equipment management efficiency, reduce costs, maintain equipment reliability, and ensure system stability. The plan is assigned to the terminal through identity permission information, and maintenance tasks are assigned in an orderly manner to avoid confusion. According to the equipment labels and maintenance items in the schedule, the equipment location is obtained, the schedule is updated, and the task is ensured to be executed as planned, the maintenance efficiency is improved, and the maintenance results are visualized for easy analysis. The maintenance terminal uploads the schedule to the intelligent inspection management platform through an encrypted protocol to improve data security. It can be said that the efficiency and accuracy of maintenance are improved through a more refined design. However, the problem brought about by this is that it is easier to find more safety hazards, which leads to a sharp increase in the workload of the corresponding departments. In fact, some problems can be temporarily suspended, so corresponding adjustments need to be made on this basis. Summary of the invention

[0004] In order to solve the problem of increasing fault identification after improving fault identification in the inspection management platform in the prior art, the present invention provides a comprehensive maintenance method for power communication equipment, which is based on an intelligent inspection management platform with a state assessment model. The platform assigns a fault code corresponding to the fault information of the communication equipment. The intelligent inspection management platform is provided with a management area definition module and an abnormal code library, and the fault code corresponding to the communication equipment in the corresponding area is stored in the abnormal code library;

[0005] Develop a maintenance plan and select a specific type of target power equipment;

[0006] Collecting historical operation data of the power equipment, the historical operation data including the fault occurrence time of all operation stages of the power equipment, the operation time of all operation stages and the observation cycle time;

[0007] During the maintenance process, the fault codes that occurred in the target power equipment during the previous maintenance cycle are matched with the known faults in the exception code library; if there is no corresponding fault code in the exception code library, the new fault code is added to the exception code library, otherwise the known fault code in the exception code library is obtained, and the processing response level of the fault is determined in combination with the time when the fault occurred; faults with the same response level are classified and processed according to the processing plan corresponding to the processing response level recorded in the exception code library.

[0008] Preferably, the processing response levels include three levels: serious faults, medium faults, and minor faults. Minor faults are ignored and do not need to be processed. The intelligent inspection management platform comes with a processing plan for medium faults, which can be executed according to the plan. Serious faults need to be reported and handled by a dedicated person.

[0009] Preferably, the specific method of fault classification in the abnormal code library is to select a type of target power equipment, add the fault occurrence time of the target power equipment with the same response level, and obtain the total fault occurrence time FT corresponding to each response level. n , add up the operating time of all operating stages of the target power equipment to obtain the sum of the operating time RT of the target power equipment; based on the sum of the fault occurrence time FT n The average failure rate FR of the target power equipment is calculated based on the ratio of the failure occurrence time of each operating stage of the target power equipment to the operating time of each operating stage, and the failure rate of each operating stage of the target power equipment is calculated based on the ratio of the sum of the operating time RT of the power equipment to the observation cycle time OP. The maximum operating frequency MUF of the target power equipment is calculated based on the ratio of the rated capacity RC of the target power equipment to the observation cycle time OP. Obtain the status assessment index FI, configure a corresponding fault code for each status assessment index FI, and assign a processing response level based on the region.

[0010] Preferably, the collected historical operation data is analyzed, and abnormal conditions with a trigger frequency lower than the average value and no direct economic loss in the area are screened and marked separately. When constructing the state assessment model, the influence weight of these abnormal conditions on the average failure rate FR and the maximum failure rate MFR indicators is reduced, so that the state assessment model reduces the response level of such fault processing after evaluating the operating state of the target power equipment to obtain the state assessment index FI. More accurately reflect the main operating state and potential risks of the equipment.

[0011] Preferably, the classification standard of the specific type of target power equipment is: a series of equipment that realizes the same function, or a set of equipment that performs the same task at the same time, and only one mode can be selected during one maintenance process.

[0012] Preferably, the series of equipment that realizes the same function includes power communication transmission equipment, power communication switching equipment, and power communication energy supply equipment. Other supporting auxiliary devices are not included.

[0013] Preferably, the complete set of equipment performing the same task includes a substation communication scenario, a dispatch center communication scenario, and a distribution network communication scenario.

[0014] Preferably, after adding a new fault code to the abnormal code library, a corresponding response plan needs to be manually designed. The newly added fault code must not be ignored.

[0015] The present invention also includes a device for executing a comprehensive maintenance method of a power communication device, comprising: a processor, and a memory connected to the processor;

[0016] The memory is used to store a computer program, and the computer program is used to execute a comprehensive maintenance method for power communication equipment;

[0017] The processor is used to call and execute the computer program in the memory.

[0018] Preferably, each individual exception code library is placed in a different memory, and the memories storing the exception code libraries are not connected to each other.

[0019] The specific advantages of the present invention are: in the prior art, by enhancing the data collection and processing capabilities and optimizing the state assessment model. An exception code library is added to evaluate known partial faults and automatically ignore some minor faults, reducing manual intervention and improving the work efficiency of inspection personnel. A more accurate judgment can also be made on the abnormalities that occur, reducing the losses caused by faults during the maintenance process. It should be noted that in different areas, the evaluation level of the exception code library for the same fault code may be different. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention.

[0021] Figure 1 It is a flow chart of a comprehensive maintenance method for electric power communication equipment of the present invention. DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It can be understood that the specific implementation methods described here are only used to explain the relevant content, rather than to limit the present disclosure.

[0023] The present invention is a further improvement based on the invention patent "Power Equipment Operation and Maintenance Method Based on Intelligent Inspection Management Platform" with the prior application number CN202311492514.9. The FI recorded in the patent, i.e. the state assessment index of the power equipment, is summarized and collected into the abnormal code library in the present invention. The present invention is limited to power communication equipment because the fault types in power communication equipment are relatively concentrated and the negative impact is relatively small.

[0024] Since the present invention involves multiple proper nouns, they are first explained here:

[0025] Management area definition module: Power equipment performs different tasks in different areas and is in different working conditions. For example, power equipment in industrial areas may have to withstand large load fluctuations and harsh environmental conditions, while power equipment in residential areas is relatively stable but has higher reliability requirements. In view of this, the module that divides and manages it based on the area is the management area definition module. This module can carry out targeted management of power equipment according to the characteristics of different areas, including formulating different inspection plans, maintenance strategies, etc., so as to better ensure the stable operation of power equipment and meet the electricity demand of each area. More importantly, based on the management of the management area definition module, the fault level classification of the same fault in different areas is different.

[0026] Abnormal code library: In the present invention, the abnormal code library is used to record various fault information occurring during the operation of the power equipment and convert the fault information into fault codes. By analyzing the historical fault data, the abnormal code library can identify common fault modes and provide suggestions for future decisions on whether to directly handle the fault.

[0027] Target power equipment: The power equipment in the present invention is mainly aimed at power communication equipment, including communication transmission equipment, such as SDH equipment, DWDM equipment and other optical transmission equipment, microwave communication equipment, and communication switching equipment, such as program-controlled switches, switches, etc.

[0028] To convert the state assessment index of power equipment into fault levels, we must first determine the fault level classification standards and determine the number of fault levels based on the characteristics of the power equipment and actual needs. They can usually be divided into three levels: severe faults, moderate faults, and minor faults, with clear ranges and feature descriptions set for each level. Then, establish the correspondence between the state assessment index and the fault level. By analyzing a large amount of historical data and summarizing actual experience, use statistical analysis methods to find out the rules and determine the fault level corresponding to different state assessment index ranges. Finally, in actual applications, continuously collect new power equipment operation data, compare and verify the conversion results with the actual equipment status, and adjust the corresponding relationship in time if there is a deviation to improve the accuracy and reliability of the conversion.

[0029] Each time the present invention is implemented, it targets a specific type of target power equipment, and the classification standard of the target power equipment is: a series of equipment that realizes the same function, such as power communication transmission equipment, power communication switching equipment, and power communication energy supply equipment;

[0030] Or a set of equipment that performs the same task at the same time, such as substation communication scenario, dispatch center communication scenario, and distribution network communication scenario. Only one mode can be selected during a maintenance process.

[0031] like Figure 1 As shown, a certain substation communication center is taken as a specific embodiment. The substation communication center is connected to an intelligent inspection management platform based on a state assessment model. The platform assigns fault codes corresponding to fault information to the communication equipment. The intelligent inspection management platform is provided with a management area definition module and an abnormal code library. The fault codes corresponding to the communication equipment in the corresponding area are stored in the abnormal code library; the regional communication equipment verifies the specific location of the substation communication center and configures the corresponding abnormal code library for it.

[0032] Formulate a maintenance plan based on the substation communication center, collect historical operation data of the power equipment, the historical operation data includes the fault occurrence time of all operation stages of the power equipment, the operation time of all operation stages and the observation cycle time;

[0033] During the maintenance process, record in detail the equipment failure phenomena found during the maintenance process. This includes but is not limited to abnormal performance of the equipment, such as indicator light status, alarm information, equipment operation sound, temperature changes, etc. Perform preliminary testing and diagnosis on the equipment to obtain more fault-related information. Professional test instruments, such as optical power meters, bit error testers, etc., can be used to measure the key parameters of the equipment. For example, the optical power output of the optical transmission equipment is measured by an optical power meter to determine whether it is within the normal range. Once the fault information is collected, it is entered into the abnormal code library, and the fault code library is automatically queried to determine whether there is a corresponding fault code and the processing level for the fault code.

[0034] Maintenance personnel still need to compare and analyze the fault description corresponding to the queried fault code with the actual detected fault phenomenon. Check whether the fault characteristics match, including the location of the fault, manifestation, impact range, etc. Finally confirm the matching result. The fault code that occurred in the target power equipment during the previous maintenance cycle is matched with the known faults in the abnormal code library; if there is no corresponding fault code in the abnormal code library, the new fault code is added to the abnormal code library, otherwise the known fault code in the abnormal code library is obtained, and the processing response level of the fault is determined in combination with the time when the fault occurred; faults with the same response level are classified, and processed according to the processing plan corresponding to the processing response level recorded in the abnormal code library.

[0035] In this embodiment,

[0036] Minor faults include:

[0037] Optical transmission equipment: The optical power fluctuates slightly, which is at the edge of the normal range but does not affect the communication quality; individual alarm indicators flash, but do not affect the overall operation of the equipment. For example, the optical power sent by the optical module is slightly lower than the normal range, but the bit error rate is still within the acceptable range.

[0038] Microwave communication equipment: A slight deviation in the microwave antenna angle has little effect on signal strength; the device's transmit power or receiving sensitivity decreases slightly, but does not affect normal communication. For example, if the antenna angle deviation is within a certain range, the signal strength attenuation is not obvious.

[0039] Program-controlled switches: A small number of ports have unstable connections, which can be automatically restored without affecting most communication services; occasional slight call processing delays occur. For example, individual ports are disconnected and automatically connected for a moment.

[0040] Softswitch equipment: Some services were slightly delayed in opening, but eventually opened successfully; there were some minor compatibility issues with the software version, but they did not affect the main services. For example, the opening time of a new service was slightly longer than normal.

[0041] High-frequency switching power supply: The output voltage or current has slight fluctuations, which are within the tolerance range of the equipment; the rectifier module has slight heat generation, but it does not affect normal operation. For example, the output voltage fluctuation is small, and the communication equipment can still operate normally.

[0042] Battery pack: The internal resistance of the battery increases slightly, but it can still meet the backup power supply time requirements; the voltage fluctuates slightly. For example, the internal resistance increases but does not affect the power supply capacity when the mains power is interrupted.

[0043] Optical cable: The appearance of the optical cable is slightly worn, but it does not affect the transmission of optical signals; the optical attenuation is slightly increased, but it is at the edge of the normal range. For example, the outer sheath of the optical cable has slight scratches, but the internal optical fiber is not damaged.

[0044] Cable: The insulation performance of the cable is slightly reduced, but it can still ensure safe operation; the grounding condition is slightly abnormal, but it does not affect the power supply of the equipment. For example, the insulation resistance is slightly lower than normal, but it does not reach a dangerous value.

[0045] It should be noted that these faults are only described in words in this embodiment, but in actual operation, they are input into the abnormal code library according to the equipment conditions obtained on site, and the abnormal code library makes its own judgment. Minor faults can be ignored directly, but they still need to be registered in the intelligent inspection management platform.

[0046] Moderate faults include:

[0047] Optical transmission equipment: The optical power dropped significantly, affecting some communication services; multiple alarm indicators were always on, and the equipment performance was affected to a certain extent. For example, the optical power sent by the optical module dropped significantly, causing bit errors or interruptions in some services.

[0048] Microwave communication equipment: The microwave antenna angle deviates greatly, and the signal strength is significantly weakened; the device's transmission power or receiving sensitivity decreases significantly, affecting the communication quality. For example, the antenna angle deviates seriously, the signal strength attenuates significantly, and the communication is stuck.

[0049] Program-controlled switches: Multiple ports are frequently disconnected, affecting a wide range of communication services; call processing is significantly delayed. For example, multiple ports are disconnected for a long time, causing some users to be unable to make calls normally.

[0050] Softswitch equipment: Some services cannot be activated or are frequently interrupted after activation; software version compatibility issues cause certain impacts on major services. For example, an important service cannot run normally, affecting user use.

[0051] High-frequency switching power supply: The output voltage or current fluctuates greatly, exceeding the normal tolerance range of the equipment; the rectifier module overheats, which may affect the life of the equipment. For example, the output voltage fluctuates frequently, and the communication equipment becomes unstable.

[0052] Battery pack: The internal resistance of the battery increases significantly, and the backup power supply time is significantly shortened; the voltage fluctuates greatly. For example, the increase in internal resistance leads to insufficient power supply time when the city power is interrupted, which may affect the normal operation of the equipment.

[0053] Optical cable: The optical cable has obvious damage on the outside, which may affect the transmission of optical signals; the optical attenuation is large and close to the fault threshold. For example, the outer sheath of the optical cable is severely damaged, and the internal optical fiber may be damaged.

[0054] Cable: The insulation performance of the cable has obviously declined, which poses a certain safety hazard; abnormal grounding may affect the stability of the equipment power supply. For example, if the insulation resistance drops to a dangerous value, it needs to be handled in time.

[0055] For medium faults, they can usually be repaired directly during the maintenance process after being determined by the exception code library.

[0056] Serious faults include:

[0057] Optical transmission equipment: The optical power is extremely low, and the communication service is completely interrupted; the equipment has a serious fault alarm and cannot work normally. For example, the optical module is completely damaged and the optical signal cannot be transmitted.

[0058] Microwave communication equipment: The microwave antenna is damaged and cannot receive or send signals; the equipment is completely inoperable. For example, the antenna is broken and communication is completely interrupted.

[0059] Program-controlled switches: Most ports are disconnected, communication services are basically paralyzed, and call processing is completely impossible. For example, a serious switch failure occurs and all users cannot make calls.

[0060] Softswitch equipment: All services cannot be activated and the system crashes; the software version is seriously incompatible, causing the entire communication network to be affected. For example, the softswitch equipment crashes and all voice and data services are interrupted.

[0061] High-frequency switching power supply: abnormal output voltage or current may damage the communication equipment; the rectifier module burns out and the power supply cannot work. For example, the output voltage is too high or too low, which may cause damage to the communication equipment.

[0062] Battery pack: The battery is completely inoperable and cannot provide backup power; the voltage is abnormal, which may cause damage to the communication equipment. For example, the battery cannot be charged or discharged, and the equipment cannot be guaranteed to operate when the city power is interrupted.

[0063] Optical cable: The optical cable is severely broken, and the optical signal is completely interrupted; it cannot be repaired. For example, the optical cable is damaged by external forces, and the communication service is completely interrupted.

[0064] Cable: The insulation performance of the cable is completely lost, which poses a serious safety hazard; the grounding fault causes the equipment to be unable to supply power normally. For example, the cable is short-circuited or broken, and the communication equipment cannot work normally.

[0065] For serious faults, it is not recommended to make modifications in real time. They need to be reported in a timely manner and handled by a professional maintenance team.
