Technical Field

[0001] The present invention relates to the technical field of communication platform operation and maintenance. Background Art

[0002] The existing communication gateway data analysis platform solves the problem that Huawei and ZTE transmission network management systems do not have the network operation status analysis function. It connects to the northbound interface of the existing network management system using FTP service by adding a new server, collects raw data, and performs big data analysis, processing, integration and classification. Finally, it displays the bit error, optical power, board temperature, etc. in a visual form, solving the problem of complex data indicator query, and can analyze the changing trend of each parameter, provide fault analysis evidence, and put forward maintenance rationalization suggestions.

[0003] However, the existing gateway data analysis platform cannot solve the problem specifically. It can only display the data and its related changes, but does not have an early warning function. The dispatching staff on duty cannot make a fault judgment based on it, and do not know the extent of the problem and how to deal with it. They lack the ability to judge the specific cause of the fault. Summary of the invention

[0004] In order to solve the technical problem in the prior art that the communication gateway data analysis platform lacks the ability to judge the specific cause of the failure, the present invention provides a rapid operation and maintenance method based on a communication resource refined management and control platform.

[0005] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0006] A rapid operation and maintenance method based on a communication resource refined management and control platform comprises the following steps:

[0007] S1. Determine whether the optical power of the control platform is normal according to the transmit and receive power data of the laser. If normal, proceed to step S2. Otherwise, manually process the alarm information according to the optical power warning prompt of the control platform;

[0008] S2. Determine whether the board is normal according to the board temperature measured by the management platform. If normal, proceed to step S3. Otherwise, manually process the alarm information according to the board temperature warning prompt of the management platform;

[0009] S3. Determine whether an error code alarm occurs on the control platform according to the alarm prompt information of the control platform. If an error code alarm occurs, proceed to the next step;

[0010] Determine whether the error is caused by a fault in the optical interface board of the management and control platform. If not, proceed to the next step.

If so, check the clock configuration of the management and control platform. If there is a configuration error, reconfigure the clock. The process ends when the bit error on the management and control platform disappears. If the bit error still exists, proceed to the next step.

[0012] Determine whether the bit error is caused by a cross-connect unit failure on the control platform. If so, replace the board of the faulty cross-connect unit. The process ends when the bit error on the control platform disappears. If the bit error still exists, proceed to the next step.

[0013] Determine whether the bit error is caused by a circuit board failure of the control platform. If so, replace the faulty circuit board. The process ends when the bit error of the control platform disappears. If the bit error still exists, proceed to the next step.

[0014] Determine whether the error is caused by abnormal optical power received by the control platform. If so, process it according to the alarm information of the control platform. The process ends after the error disappears. If the error still exists, proceed to the next step.

[0015] Determine whether the error is caused by the environment of the control platform not meeting the temperature and humidity index requirements. If so, adjust the temperature and humidity. The process ends when the error disappears. If the error still exists, proceed to the next step.

[0016] Determine whether the error code is caused by the grounding fault of the control platform. If so, check whether the relevant equipment is well grounded and handle it. The process ends when the error code of the control platform disappears. If the error code still exists, proceed to the next step.

[0017] Determine whether the bit error is caused by a cable fault on the management and control platform. If so, measure the transmit optical power of the opposite board and the receive optical power of the local board to see if they are within the normal optical power receiving range of the board. If the transmit optical power on the opposite end is abnormal, execute the steps to determine whether the bit error is caused by a cross-unit fault on the management and control platform; if the receive optical power on the local end is abnormal, proceed to the next step.

[0018] Determine whether the bit error is caused by a fault in the cable connecting the extended subrack of the management and control platform. If so, replace the cable. The process ends when the bit error on the management and control platform disappears. If the bit error still exists, proceed to the next step.

[0023] Determine whether the bit error is caused by a clock unit failure. If so, replace the faulty board. The process ends when the bit error on the management and control platform disappears. If the bit error still exists, proceed to the next step.

[0024] The step of processing according to the alarm information of the control platform includes the following steps:

[0025] Check the alarm information on the control platform;

[0026] When the INPWR_ABN alarm appears in the alarm information, handle the INPWR_ABN alarm according to the prompt information of the SDH communication transmission platform; when the INPWR_ABN alarm does not appear in the alarm information, contact the staff for manual processing.

[0027] The temperature index requirement is: 0℃-45℃, and the relative humidity index requirement is: 10%-90%. When the environment of the control platform does not meet the environmental temperature and humidity index requirements, check and adjust the operating status of the air conditioner in the computer room to ensure that the temperature and humidity of the computer room are within the appropriate range;

[0028] When the alarm information on the management and control platform shows a temperature exceeding limit alarm, the SDH communication transmission platform prompts an information processing temperature exceeding limit alarm.

[0029] When the grounding fault occurs on the control platform in the steps described above, check whether the grounding busbar in the user's computer room, the transmission equipment cabinet and the computer room grounding busbar, the front door and side door of the cabinet and the cabinet, the sub-rack and the cabinet, the signal cable, DDF, ODF, network management equipment, power equipment, and docking equipment are well grounded. Otherwise, re-ground them.

[0030] When the power fluctuation value sent and received by the laser is less than 5dB from the overload point or greater than 3dB from the sensitivity, it is judged that the optical power of the control platform is abnormal.

[0031] The step S2 adjusts the temperature of the single board by adjusting the operating environment temperature in the computer room.

[0032] The advantages of the present invention compared with the prior art are:

[0033] The technical solution of this application can quickly determine the specific cause of the failure of the control platform, making it easier for maintenance personnel to perform maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 It is a flow chart of the laser sending and receiving power detection of the present invention.

[0035] Figure 2 This is a single board temperature detection flow chart of the present invention.

[0036] Figure 3 It is a flow chart of error detection of background blocks in the regeneration section and multiplexing section of the present invention. DETAILED DESCRIPTION

[0037] The existing intelligent gateway analysis platform consists of two parts: functional module and data module:

[0038] There are 7 functional modules, namely: multiplexing section background block error module, regeneration section background block error module, optical power sending module, optical power receiving module, single board temperature module, ledger management module, and equipment diagnosis module.

[0039] There are 6 data modules, namely: data acquisition module, data analysis module, data processing module, big data integration module, database modeling and database design.

[0040] The intelligent gateway analysis platform collects, analyzes and processes data from the existing Huawei and ZTE network management systems through data modules, and finally displays information such as bit errors, optical power, board temperature, and warnings in the form of tables and curves, providing a reference for the work and decision-making of operation and maintenance personnel.

[0041] Analyze historical log data, explore the temporal and spatial correlations between faults, alarms, and performance data, and collect statistics on past faults to identify frequent fault points or high-risk points.

[0042] Based on the knowledge of historical analysis, real-time data is analyzed to conduct pre-warning and post-fault location analysis. However, the accuracy of this type of warning needs to take into account the current amount of data, and can only predict the types of faults that have occurred in history. For devices of the same type, the exploration of AI model generalization can be carried out within a certain range, that is, based on the fault time analysis in a certain area, similar problems in other areas can be warned. According to the formulated fault analysis strategy, data with large changes can be perceived in advance and alarmed in advance. This greatly avoids the situation where the SDH network manager notifies maintenance personnel in the form of an alarm to take measures to restore the normal operation of the network only when the fault has already occurred.

[0043] The present invention provides a rapid operation and maintenance method based on a communication resource refined management and control platform, comprising the following steps:

[0044] S1. Figure 1 As shown, the optical power of the control platform is judged to be normal according to the transmit and receive power data of the laser. If it is normal, continue to execute step S2, otherwise it is manually processed according to the alarm information of the optical power early warning prompt of the control platform; when the power fluctuation value of the laser transmission and reception is less than 5dB of the overload point or greater than 3dB of the sensitivity, it is judged that the optical power of the control platform is abnormal. If the fluctuation value of the laser transmission power or the fluctuation value of the receiving power is not less than 5dB of the overload point or greater than 3dB of the sensitivity, proceed to the next step.

[0045] S2. Figure 2 As shown, the normal operating temperature of the board is -5℃~65℃. The board temperature measured by the management and control platform is used to determine whether the board is normal. If it is normal, continue to step S3, otherwise, manually handle it according to the board temperature warning prompt information of the management and control platform; if the board temperature fluctuates greatly, the operation and maintenance personnel will handle the fault according to the board temperature warning prompt information in the lower left corner, and the board temperature can be adjusted by adjusting the operating environment temperature in the computer room; if the board temperature fluctuates slightly, proceed to the next step.

[0046] like Figure 3 As shown, S3. Determine whether an error code alarm occurs on the management and control platform according to the alarm prompt information of the management and control platform. If an error code alarm occurs, continue to execute step S4; the alarm information of the management and control platform will directly display whether there is an error code alarm and the specific cause of the error code.

[0047] S4. According to the alarm information of the control platform, determine whether the error is caused by the optical interface board failure of the control platform. If not, continue to step S5; if so, replace the faulty optical interface board, and end after determining that the error of the control platform disappears. If the error still exists, continue to step S5;

[0048] S5. Determine whether the bit error is caused by the clock failure of the control platform based on the alarm prompt information of the control platform. If not, continue to execute step S6; if so, check the clock configuration of the control platform. If there is a configuration error, reconfigure the clock. The process ends after determining that the bit error of the control platform disappears. If the bit error still exists, continue to execute step S6.

[0049] S5-1. According to the alarm information of the management and control platform, determine whether the error is caused by the network element clock failure. If so, reconfigure the network element clock and determine that the control and control platform error disappears. If the error still exists, proceed to step S5-2.

[0050] S5-2. According to the alarm information of the management and control platform, determine whether the error is caused by the clock failure of the entire network. If so, reconfigure the clock of the entire network, determine that the error of the management and control platform disappears, and end. If the error still exists, continue to step S5-3;

[0051] S5-3. Determine whether the bit error is caused by a clock unit failure based on the alarm prompt information of the management and control platform. If so, replace the faulty board of the unit. The process ends after determining that the bit error of the management and control platform disappears. If the bit error still exists, continue to execute step S6.

[0052] S6. According to the alarm information of the management and control platform, determine whether the error is caused by the cross-unit failure of the management and control platform. If so, replace the faulty cross-unit board, and end the management and control platform after the error disappears. If the error still exists, continue to step S7;

[0053] S7. According to the alarm information of the management and control platform, determine whether the error is caused by the circuit board failure of the management and control platform. If so, replace the faulty circuit board, and end after determining that the error of the management and control platform disappears. If the error still exists, continue to step S8;

[0054] S8. According to the alarm information of the control platform, it is determined whether the error is caused by the abnormal receiving optical power of the control platform. If so, it is processed according to the alarm information of the control platform. It is determined that the error of the control platform disappears and ends. If the error still exists, continue to step S9;

[0055] S8-1. Check the alarm information on the control platform;

[0056] S8-2. When the INPWR_ABN alarm appears in the alarm information, handle the INPWR_ABN alarm according to the prompt information of the SDH communication transmission platform; when the INPWR_ABN alarm does not appear in the alarm information, contact the staff for manual processing.

[0057] S9. According to the alarm information of the control platform, determine whether the error is caused by the environment of the control platform not meeting the requirements of the ambient temperature and humidity index. If so, adjust the temperature and humidity, and end after determining that the error of the control platform disappears. If the error still exists, continue to execute step S10;

[0058] The temperature index requirements are: 0℃-45℃, and the relative humidity index requirements are: 10%-90%. When the environment of the control platform does not meet the environmental temperature and humidity index requirements, check and adjust the operating status of the air conditioner in the computer room to ensure that the temperature and humidity in the computer room are within the appropriate range; when the alarm information on the control platform shows a temperature limit alarm, the SDH communication transmission platform prompts an information processing temperature limit alarm.

[0059] S10. Determine whether the error is caused by the grounding failure of the control platform according to the alarm prompt information of the control platform. If so, check whether the relevant equipment is well grounded and handle it. The process ends after the error of the control platform disappears. If the error still exists, continue to execute step S11. When the grounding failure of the control platform occurs, check whether the grounding bus of the user's computer room, the transmission equipment cabinet and the computer room grounding bus, the front door and side door of the cabinet and the cabinet, the sub-rack and the cabinet, the signal cable, DDF, ODF, network management equipment, electrical equipment, and docking equipment are well grounded. Otherwise, re-ground them.

[0060] S11. According to the alarm information of the management and control platform, determine whether the bit error is caused by the cable fault of the management and control platform. If so, measure the transmit optical power of the opposite board and the receive optical power of the local board to see whether they are within the normal optical power receiving range of the board. If the transmit optical power of the opposite end is abnormal, execute step S6; if the receive optical power of the local end is abnormal, continue to execute step S12;

[0061] S12. According to the alarm information of the management and control platform, determine whether the error is caused by the failure of the cable connecting the extension subrack of the management and control platform. If so, replace the connecting cable, and end after determining that the error of the management and control platform disappears. If the error still exists, continue to step S13;

[0062] S13. Determine whether the bit error is caused by the inappropriate optical interface type of the optical interface board of the management and control platform according to the alarm prompt information of the management and control platform. If so, match the optical module of the appropriate optical interface type, replace the pluggable optical module or increase the optical attenuation. The process ends after determining that the bit error of the management and control platform disappears. If the bit error still exists, continue to execute step S1.

[0063] After the device reports a bit error, analyze the characteristics of the bit error and gradually locate the fault to a single station. Taking the optical power of the circuit board as an example, if the received optical power is too high or too low, the optical module will receive the optical signal abnormally and cause B1, B2, B3 or BIP bit errors. Therefore, when the device reports a large number of various types of bit errors, first test whether the received optical power of this station is normal.

[0064] Through the development and application of the gateway data analysis platform, we can explore the spatiotemporal correlation between faults, alarms, and performance data, and conduct statistics on past faults to find frequent faults or high-risk points. Based on the knowledge of historical analysis, real-time data can be analyzed to achieve pre-warning and post-fault location analysis. For devices of the same type, we can explore the generalization of AI models within a certain range, that is, based on the fault time analysis in a certain area, we can warn of similar problems in other areas.

[0065] Users can find abnormal data in time and handle it, which avoids the situation of handling it only when the fault occurs. According to the formulated alarm analysis strategy, the data with large changes can be perceived in advance, which is convenient for network management and operation personnel to quickly analyze and process the data. It can be combined with SDH network management and on-site equipment to quickly locate fault warnings and handle them in time to avoid business interruption caused by the spread of faults.

[0066] The gateway data platform can be promoted to other cities and even enterprises that use SDH network management. Through the actual application of the system and the comparison with previous operation and maintenance methods, it is found that the platform can greatly reduce the operation and maintenance burden, give early warning of degraded signals before failures occur, ensure the maximum connectivity of services, and save a lot of manpower and material costs. It has a great return on investment value and greatly reduces the operation and maintenance costs for enterprises.

[0067] Actual case: From 3:00 to 3:15 a.m. on January 26, 2024, Huawei transmitted 500kV Huanghai transformer 8 slot 1 port, which could not receive the optical power of Zhuanghe transformer, and the optical signal was interrupted. According to the flow chart, each item was checked, as shown in the following table. After verification by on-site personnel, the 500kV Huangzhuang 1# line 3 and 4 cores of the optical path from Dalian Level 4 network Huawei B network 500kV Huanghai transformer to Zhuanghe transformer had a breakpoint 9.13 km away from the Huanghai transformer. After analysis, the possible cause of the fault was the recent sudden drop in temperature, which caused the optical cable to be frozen and caused service interruption. After the core was reversed on site, the optical path returned to normal.
