Description

Technical Field

[0001] The present invention relates to the technical field of cable tunnel operation and maintenance management, and in particular to a cable tunnel operation and maintenance integrated management method and system. Background Art

[0002] With the continuous development of power and communication infrastructure, cable tunnels, as important carriers of power transmission and communication networks, face complex load, maintenance and risk assessment challenges in their operation and maintenance management.

[0003] Currently, existing technologies often use simple static parameter calculations, which fail to dynamically reflect the actual operation and maintenance conditions of cable tunnels under different load conditions, making it difficult to adapt to environmental changes in real time. In addition, existing operation and maintenance methods lack comprehensive consideration of multiple influencing factors and the complex interactions between various factors. This will lead to inefficient allocation of operation and maintenance tasks and even miss maintenance needs in key areas. For abnormal conditions in cable tunnels, including overload operation and equipment failure, current existing technologies lack the ability to evaluate and handle them in real time, which can easily lead to equipment overload damage and omission of maintenance tasks.

[0004] Therefore, those skilled in the art provide a cable tunnel operation and maintenance integrated management method and system to solve the problems raised in the above background technology. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide a comprehensive management method and system for cable tunnel operation and maintenance, so as to improve the accuracy and real-time performance of operation and maintenance work, and achieve the effects of risk assessment and judgment, workload optimization and operation and maintenance efficiency feedback, abnormal state judgment and flexible adjustment, and self-optimization.

[0006] In order to solve the above problems, the present invention provides the following technical solutions: The comprehensive management method for cable tunnel operation and maintenance has the following specific implementation steps: Step 1: Use the data acquisition module to collect basic data related to the current cable tunnel operation and maintenance management, including load factor FX, total channel volume TS, total cable length L, load safety threshold AH, current load SF, maintenance speed factor WS, maximum channel volume TS max ; Step 2: The basic data is transferred to the operation and maintenance management assessment module, which first calculates and outputs the risk trigger value D. Under the warning condition of D < 0, the warning module provides an operation and maintenance warning; Step 3: Based on the operation and maintenance warning provided by the warning module, and using the operation and maintenance management evaluation module, calculate and output the maintenance workload WG and the operation and maintenance efficiency value X in sequence; Step 4: Use the dynamic adjustment module to analyze and adjust the operation and maintenance strategy based on the risk trigger value D, maintenance workload WG, and operation and maintenance efficiency value X. Step 5: Use the display generation module to output the operation and maintenance strategy after analysis and adjustment; The dynamic adjustment module needs to dynamically adjust the load factor FX according to the update cycle and operation and maintenance strategy; The operation and maintenance management evaluation module includes a load risk early warning unit, an operation and maintenance resource allocation unit and an operation and maintenance efficiency evaluation unit.

[0007] Further: the equipment used in the data acquisition module includes sensors, acquisition cards, data transmission networks, and monitoring systems; The equipment used in the operation and maintenance management evaluation module includes computers and operation and maintenance management systems; The equipment used in the dynamic adjustment module includes a data analysis platform, an intelligent control system, and an adjustment actuator; The equipment used in the early warning module includes a trigger alarm; The equipment used by the display generation module includes a report generation system.

[0008] Further: The calculation formula of the load risk warning unit is as follows: D=FX×(TS+L)-AH; FX=SF / AH; in: D is the risk trigger value; FX is the load factor; TS is the total number of channels, TS represents the total number of channels in the cable tunnel; L is the total length of the cable; AH is the load safety threshold, which is pre-set based on experimental and historical operation and maintenance load conditions; SF is the current load; The calculation of TS+L is based on the basic cable operation and maintenance workload of the total cable length L, and the total channel volume TS reflects the additional factors affecting the maintenance difficulty; If D>0, the operation and maintenance status of the cable tunnel is normal, indicating that the cable tunnel can withstand the current load SF and there is no need to trigger an early warning; If D<0, it means that the cable tunnel load exceeds the safety threshold, that is, FX×(TS+L)>AH, and an early warning is triggered and the operation and maintenance strategy is adjusted.

[0009] Furthermore, the calculation formula of FX=SF / AH in the load risk warning unit is the initial calculation formula under the initial operation and maintenance state, and according to the manually set update cycle, the load factor FX needs to be calculated and updated regularly according to the update cycle. The specific calculation formula is as follows: ; in: FX0 is the updated load factor; △FX is the load difference, which reflects the difference in load between the beginning and the end of the update cycle; FX max is the maximum load factor, FX max Reflects the maximum value of the load within the update cycle; FX0>1, indicating that the load of the cable tunnel has exceeded the safety threshold; If FX0<1, it means the load is within the safe range.

[0010] Further: Based on the trigger warning situation of D<0, the calculation formulas of the operation and maintenance resource allocation unit and the operation and maintenance efficiency evaluation unit are as follows: Operation and maintenance resource allocation unit: ; WS=WS s / WS m ; in: WG is the maintenance workload; WS is the maintenance speed coefficient; WS s is the current maintenance workload, WS s Indicates the amount of maintenance work completed per unit time; WS m Maintain workload for target, WS m Indicates the expected amount of maintenance work to be completed per unit time; TS max is the maximum total number of channels; The square root calculation can reduce the impact of load on operation and maintenance workload, and Can measure the relationship between load factor FX and maintenance speed; If WG>0, it means that the maintenance workload of the cable tunnel is relatively large, requiring more resources and time; If WG<0, it means that the maintenance workload is relatively small and requires a small amount of resources and time; Evaluation unit for operation and maintenance effectiveness: ; in: X is the operation and maintenance efficiency value; The calculation reflects the resources required to maintain the overall operation and maintenance efficiency. When the maintenance workload WG is known, the overall efficiency is adjusted according to the size and load of the tunnel, as well as the operation and maintenance speed. The calculation is used to eliminate the negative impact caused by the increase in the number of channels; If X>0, it means that the overall operation and maintenance efficiency is high, and the cable tunnel maintenance efficiency is good, requiring short operation and maintenance time; If X<0, it means that the overall operation and maintenance efficiency is low and needs to be optimized.

[0011] Further: Based on the trigger warning situation of D<0, there are two situations: D<0 and close to 0 and D<0 and far from 0. The specific analysis is as follows: When D < 0 and is close to 0, then WG < 0 and X > 0, which means that the cable tunnel load is close to the safety threshold but has not exceeded it. At this time, the maintenance workload WG tends to 0 and is negative, which means that the maintenance workload WG is low and does not require too many resources. The operation and maintenance efficiency value X is greater than 0, indicating that although the load is close, the operation and maintenance efficiency is high and the task can be completed in a short time. Adjustment measures: The load factor FX needs to be monitored and timely inspections arranged to avoid excessive load and system crash; When D < 0 and is far from 0, then WG > 0 and X < 0, indicating that the cable tunnel load is far below the safety threshold and the load is low. In this case, the maintenance workload WG is large, indicating that high maintenance workload and resources are required, but the operation and maintenance efficiency value X will be lower than 0, indicating low operation and maintenance efficiency. Adjustment measures: It is necessary to optimize resource utilization and adjust the maintenance speed factor WS.

[0012] The cable tunnel operation and maintenance integrated management system includes a data acquisition module, an operation and maintenance management evaluation module, an early warning module, a dynamic adjustment module, and a display generation module. It is characterized by: The data acquisition module is used to monitor and collect the working status of the cable tunnel in real time, and transmit basic data related to the working status to the operation and maintenance management evaluation module; The operation and maintenance management evaluation module is used for running the calculation of the operation and maintenance management system; The early warning module is used to issue early warnings for the calculated operation and maintenance risks; The dynamic adjustment module is used to adjust the system load and operation and maintenance strategy according to feedback; The display generation module is used to integrate calculation results and adjustment suggestions to generate a report.

[0013] Furthermore: the data acquisition module collects basic data of the cable tunnel from different sensors, acquisition equipment, monitoring equipment and input terminals, integrates the data and transmits them together to the operation and maintenance management evaluation module for corresponding calculation.

[0014] The effects of the above solution are as follows: 1. The present invention avoids operation and maintenance problems caused by excessive or insufficient load by regularly and dynamically adjusting the load factor FX. This enables the system to optimize the load factor FX in real time according to the actual workload and environmental conditions, thereby ensuring that the cable tunnel is in the optimal operating state and improving the accuracy and real-time performance of operation and maintenance work.

[0015] 2. The present invention uses the risk trigger value D calculated by the load risk warning unit to promptly and intuitively evaluate and determine whether the calculation of subsequent formulas needs to be triggered. Furthermore, through dynamic feedback from the load risk warning unit, the system can automatically perform further analysis and adjustments when D < 0 to ensure the validity of the calculation. Subsequently, through calculations by the operation and maintenance resource allocation unit and the operation and maintenance efficiency evaluation unit, the system can not only optimize the maintenance workload WG, but also form a closed-loop adjustment mechanism through feedback from the operation and maintenance efficiency value X, thereby improving overall operation and maintenance efficiency and achieving continuous optimization of the operation and maintenance process.

[0016] 3. The present invention uses different operation and maintenance adjustments when D<0 and close to 0 and D<0 and far from 0 to automatically perform precise processing and adjustments when the cable tunnel is in an abnormal state to prevent equipment failure and workload overload. The closed-loop feedback mechanism formed in this way can ensure real-time optimization and continuous improvement of the cable tunnel operation and maintenance management system, and the feedback mechanism can promptly discover potential problems and make adjustments to ensure safe and efficient operation of the cable tunnel.

[0020] See also Figure 1-4 The present invention provides a cable tunnel operation and maintenance integrated management system based on the cable tunnel operation and maintenance integrated management method, including a data acquisition module, an operation and maintenance management evaluation module, an early warning module, a dynamic adjustment module, and a display generation module, which is characterized by: Data acquisition module: used to monitor and collect the working status of the cable tunnel in real time, and transmit basic data related to the working status to the operation and maintenance management evaluation module; Operation and maintenance management evaluation module: used for calculation of operation and maintenance management system; Early warning module: used to issue early warnings for calculated operation and maintenance risks; Dynamic adjustment module: used to adjust system load and operation and maintenance strategies based on feedback; Display generation module: used to integrate calculation results and adjustment suggestions and generate reports; The data acquisition module collects basic data of the cable tunnel from different sensors, acquisition equipment, monitoring equipment and input terminals, integrates the data and transmits them to the operation and maintenance management evaluation module for corresponding calculations.

[0021] In this embodiment, the integrated cable tunnel operation and maintenance management method and system, through scientific calculation and dynamic feedback, can ensure a balance between cable tunnel operation and maintenance workload, efficiency, and safety load, avoiding the resource waste and over-scheduling problems common in traditional management methods. Each module of the system is centered around a load risk warning unit, an operation and maintenance resource allocation unit, and an operation and maintenance efficiency evaluation unit. Through real-time data collection, precise calculation, dynamic adjustment, and feedback mechanisms, it provides a comprehensive cable tunnel operation and maintenance solution. Through the combination of this series of steps, modules, and equipment, the cable tunnel operation and maintenance integrated management method and system can dynamically adjust and optimize operation and maintenance strategies. The core advantages of this system are: Dynamic adjustment capability: Through real-time adjustment of load factor FX and operation and maintenance efficiency, operation and maintenance activities can flexibly respond to different loads and complex environments; Feedback closed-loop mechanism: The calculation results of the load risk warning unit, operation and maintenance resource allocation unit, and operation and maintenance efficiency evaluation unit are fed back to the system to ensure sustainable optimization of operation and maintenance activities; Intelligent decision support: The system can provide scientific operation and maintenance adjustment plans and reports to help make the best decisions.

[0022] See also Figure 1-4 , the calculation formula of the load risk warning unit is as follows: D=FX×(TS+L)-AH; FX=SF / AH; in: D is the risk trigger value; FX is the load factor; TS is the total number of channels, TS represents the total number of channels in the cable tunnel; L is the total length of the cable; AH is the load safety threshold, which is pre-set based on experimental and historical operation and maintenance load conditions; SF is the current load; The calculation of TS+L is based on the basic cable operation and maintenance workload of the total cable length L, and the total channel volume TS reflects the additional factors affecting the maintenance difficulty; If D>0, the operation and maintenance status of the cable tunnel is normal, indicating that the cable tunnel can withstand the current load SF and there is no need to trigger an early warning; If D<0, it means that the cable tunnel load exceeds the safety threshold, that is, FX×(TS+L)>AH, and an early warning is triggered and the operation and maintenance strategy is adjusted; In this embodiment, the FX×(TS+L) component first calculates the comprehensive workload of the cable tunnel. This is calculated by considering the relationship between the load factor FX, the total number of channels in the cable tunnel TS, and the total cable length L. FX is the load factor, which represents the ratio between the system load intensity and the standard load threshold, reflecting the system's workload. TS is the number of channels in the cable tunnel, reflecting the complexity and scale of the cable tunnel. More channels mean more cables require maintenance. L is the total length of the cable, representing the physical size and workload of the cable. The calculation of FX×(TS+L) yields a weighted workload based on the load, number of channels, and cable length. The calculated value can describe the magnitude of the overall workload of the cable tunnel and directly influence subsequent operation and maintenance measures. Afterwards, the actual load is assessed to see if it exceeds the safety range by subtracting the load safety threshold AH. AH represents the upper limit of the safe load for the cable tunnel. If the calculated result is greater than 0, the load is normal. If it is less than or equal to 0, the load exceeds the safety threshold and requires immediate attention. This calculation provides the risk assessment result for the cable tunnel. Specifically, when D<0, it means that the load of the cable tunnel has exceeded the safety threshold, which usually means that there is a potential safety risk in the system. In this case, it is meaningless to continue to execute the subsequent operation and maintenance resource allocation unit and the operation and maintenance efficiency unit calculation, because the current operation and maintenance tasks and workload cannot be effectively evaluated and executed when the load exceeds the standard. At this time, emergency measures should be taken as a priority. When D>0, it means that the system is still within the safe load range, and it makes sense to continue calculating the operation and maintenance resource allocation unit and the operation and maintenance efficiency unit. In this case, the operation and maintenance plan can be optimized by calculating the operation and maintenance resource allocation unit and the operation and maintenance efficiency unit, thereby improving efficiency and saving resources.

[0023] See also Figure 1-4 Based on the trigger warning situation of D<0, the calculation formulas for the operation and maintenance resource allocation unit and the operation and maintenance efficiency evaluation unit are as follows: Operation and maintenance resource allocation unit: ; WS=WS s / WS m ; in: WG is the maintenance workload; WS is the maintenance speed coefficient; WS s is the current maintenance workload, WS s Indicates the amount of maintenance work completed per unit time; WS m Maintain workload for target, WS mIndicates the expected amount of maintenance work to be completed per unit time; TS max is the maximum total number of channels; The square root calculation can reduce the impact of load on operation and maintenance workload, and Can measure the relationship between load factor FX and maintenance speed; If WG>0, it means that the maintenance workload of the cable tunnel is relatively large, requiring more resources and time; If WG<0, it means that the maintenance workload is relatively small and requires a small amount of resources and time; Evaluation unit for operation and maintenance effectiveness: ; in: X is the operation and maintenance efficiency value; The calculation reflects the resources required to maintain the overall operation and maintenance efficiency. When the maintenance workload WG is known, the overall efficiency is adjusted according to the size and load of the tunnel, as well as the operation and maintenance speed. The calculation is used to eliminate the negative impact caused by the increase in the number of channels; If X>0, it means that the overall operation and maintenance efficiency is high, and the cable tunnel maintenance efficiency is good, requiring short operation and maintenance time; If X<0, it means that the overall operation and maintenance efficiency is low and needs to be optimized.

[0024] In this embodiment, the operation and maintenance resource allocation unit The optimized value of the maintenance workload is partially calculated. The square root operation of the load factor FX can smooth out excessively high load values, making the load impact gradually decrease, thereby avoiding the impact of excessive load increases on the operation and maintenance workload. Through this calculation, the actual time and workload required for operation and maintenance can be obtained. The greater the load, the more difficult the operation and maintenance, the faster the maintenance, and the less workload required. The risk trigger value D and the total channel TS and the maximum channel TS based on the load risk warning unit result are partially calculated. max Adjust the ratio between them to further optimize the maintenance workload. This part corrects the maintenance workload by adjusting the ratio of the number of channels. If the number of channels is close to the maximum total number of channels TS max , which means that the tunnel is large in scale and requires more operation and maintenance resources, so the workload after adjustment will increase. This part can flexibly adjust the maintenance workload to ensure that the appropriate operation and maintenance workload can be obtained under different channel numbers and cable tunnel sizes; The operation and maintenance resource allocation unit optimizes the cable tunnel maintenance workload WG by combining the risk trigger value D obtained from the load risk warning unit. The maintenance workload WG provides the basis for subsequent operation and maintenance decisions. Through the operation and maintenance resource allocation unit, the system can dynamically adjust the cable tunnel operation and maintenance workload WG to ensure that the cable tunnel maintenance work is optimized according to the current load status and maintenance conditions, thereby improving operation and maintenance efficiency. Evaluate the operation and maintenance effectiveness unit The overall operation and maintenance efficiency of the cable tunnel is calculated in part. This part of the calculation reflects the resources required to maintain the overall operation and maintenance efficiency. When the maintenance workload WG is known, the overall efficiency is adjusted according to the size and load of the tunnel, as well as the operation and maintenance speed. This part is used to adjust the efficiency of the system and takes into account the total number of channels TS and the maximum number of channels TS in the cable tunnel. max , and correct the operation and maintenance efficiency. Among them, the square root of the total number of channels TS is calculated to smooth the impact of the increase in the number of channels on the operation and maintenance efficiency. This is because the increase in the total number of channels TS will reduce the operation and maintenance efficiency, so the square root operation is used to mitigate this impact. Therefore, this part of the calculation is used to eliminate the negative impact brought by the increase in the number of channels in the system and ensure the sustainability of the cable tunnel operation and maintenance efficiency; The operation and maintenance efficiency evaluation unit evaluates the overall efficiency of cable tunnel operation and maintenance by combining the calculation results of the operation and maintenance resource allocation unit and various parameters of the cable tunnel. The results can reflect the efficiency and effectiveness of the operation and maintenance process and provide a basis for subsequent adjustments. The calculation results of the operation and maintenance efficiency evaluation unit will affect the load risk warning unit, forming a feedback mechanism. That is, the results of the operation and maintenance efficiency evaluation unit can influence the load risk warning unit through efficiency evaluation, thereby achieving continuous optimization of the system. This closed-loop mechanism ensures dynamic adjustment of operation and maintenance management and improves the adaptability and stability of the entire system. Evaluating the operation and maintenance efficiency unit provides a very important decision-making basis for operation and maintenance management. The calculation result of the operation and maintenance efficiency value X can help determine whether the current operation and maintenance has achieved the expected results and decide whether adjustments are needed.

[0025] See also Figure 1-4 Based on the trigger warning situation of D<0, there are two situations: D<0 and close to 0 and D<0 and far away from 0. The specific analysis is as follows: When D < 0 and is close to 0, then WG < 0 and X > 0, which means that the cable tunnel load is close to the safety threshold but has not exceeded it. At this time, the maintenance workload WG tends to 0 and is negative, which means that the maintenance workload WG is low and does not require too many resources. The operation and maintenance efficiency value X is greater than 0, indicating that although the load is close, the operation and maintenance efficiency is high and the task can be completed in a short time. Adjustment measures: The load factor FX needs to be monitored and timely inspections arranged to avoid excessive load and system crash; When D < 0 and is far from 0, then WG > 0 and X < 0, indicating that the cable tunnel load is far below the safety threshold and the load is low. In this case, the maintenance workload WG is large, indicating that high maintenance workload and resources are required, but the operation and maintenance efficiency value X will be lower than 0, indicating low operation and maintenance efficiency. Adjustment measures: It is necessary to optimize resource utilization and adjust the maintenance speed factor WS.

[0026] In this embodiment, the operation and maintenance efficiency value X obtained by evaluating the operation and maintenance efficiency unit is reversely influenced by the load risk warning unit to adjust the key parameters of the load factor FX and the maintenance speed factor WS, forming an optimization closed loop. Each operation and maintenance adjustment is fed back to the load risk warning unit by the operation and maintenance efficiency evaluation unit, and the load status and operation and maintenance strategy are updated in real time. This makes the entire cable tunnel operation and maintenance management process more accurate and flexible, and can adapt to environmental changes at any time. When the performance evaluation result (operation and maintenance efficiency value X) in the operation and maintenance efficiency evaluation unit shows an abnormality, it can drive adjustments to the load risk warning unit, thereby changing the load factor FX and other parameters, thereby optimizing the load status. This dynamic adjustment ensures that the operation and maintenance workload and efficiency are always at an optimal state, avoiding problems such as overload and waste of operation and maintenance resources. By evaluating the impact of operational efficiency units, the system can automatically adjust based on actual operational efficiency, rather than relying on fixed preset parameters. This adaptive capability improves the accuracy and efficiency of cable tunnel operations and ensures the long-term stability of the entire operation and maintenance system. Specifically, when D < 0 and approaches 0, then the adjustment measures when WG < 0 and X > 0 require constant monitoring of load changes to ensure that the load does not continue to increase, especially during high-load periods. Therefore, necessary inspection measures should be taken to ensure the stability of the cable tunnel. Although the current load SF is close to the critical value, the operation and maintenance workload is low. Appropriately increasing the inspection frequency and maintenance tasks can prevent the load from continuing to rise. Strengthening monitoring and adjusting the maintenance frequency and method can ensure flexible response when the load approaches the threshold. This strategy can identify loads approaching the safety margin in advance and take measures to prevent the problem from worsening, effectively preventing system failures due to excessive loads, and ensuring the stability of system operation to avoid accidents. When D < 0 and is far from 0, WG > 0, and X < 0, in the adjustment measures, although the load is low, excessive maintenance wastes valuable operation and maintenance resources. Therefore, resource allocation should be optimized to improve operation and maintenance efficiency. If the workload of operation and maintenance tasks is high but the operation and maintenance efficiency is low, it is necessary to adjust the maintenance speed coefficient WS and change the maintenance method to speed up the operation and maintenance process without increasing excessive resource investment. In addition, avoid excessive human and material resources from being invested in low-load areas, reduce unnecessary inspection and maintenance tasks, and ensure maximum operation and maintenance efficiency. This adjustment measure can avoid excessive resource consumption, improve operation and maintenance efficiency, reduce unnecessary inspection and maintenance tasks, save operation and maintenance resources and funds, optimize the economic benefits of operation and maintenance, and adjust the operation and maintenance strategy in time according to load changes, making the operation and maintenance plan more flexible and efficient.

[0027] For example 2, please refer to Figure 1-4 The calculation formula of FX=SF / AH in the load risk warning unit is the initial calculation formula under the initial operation and maintenance state. According to the manually set update cycle, the load factor FX needs to be calculated and updated regularly according to the update cycle. The specific calculation formula is as follows: ; in: FX0 is the updated load factor; △FX is the load difference, which reflects the difference in load between the beginning and the end of the update cycle; FX max is the maximum load factor, FX max Reflects the maximum value of the load within the update cycle; FX0>1, indicating that the load of the cable tunnel has exceeded the safety threshold; If FX0<1, it means the load is within the safe range; The initial load factor FX calculation of this embodiment reflects the ratio of the current load SF of the cable tunnel to its safe load. When the load factor FX is too high, it means that the load of the tunnel is close to / exceeds the safe load threshold AH, which may cause cable damage, excessive temperature, and even fire safety hazards. However, the load of the cable tunnel is not static. It is affected by environmental factors such as temperature, humidity, and current fluctuations. Therefore, it becomes The calculation formula can flexibly adjust the maintenance strategy by monitoring the load changes in real time, ensuring that the cable tunnel is always in a safe working state under changing environmental conditions; Dynamically adjusting the load factor FX can help operation and maintenance personnel optimize resource allocation. The operating load of the cable tunnel will gradually increase during long-term use. Therefore, the operation and maintenance system needs to have a certain degree of flexibility. Dynamically adjusting the load factor FX can quickly respond to the increase / decrease of the load and, by considering the load difference △FX and the maximum load factor, FX max , can promptly identify abnormal changes in load and adjust operation and maintenance strategies to improve system reliability and long-term operational stability; Dynamic load factor FX also provides more accurate data support, enabling preventive measures to be taken before the load is about to exceed the standard. This preventive maintenance not only reduces the occurrence of sudden failures but also extends the service life of the equipment. In summary, the beneficial effects of dynamically adjusting the load factor FX are mainly reflected in improving safety, optimizing resource allocation, improving operation and maintenance efficiency and system flexibility, as well as supporting decision-making and preventive maintenance. By flexibly adjusting the maximum load factor FXmax according to actual conditions, it can ensure that the operation and maintenance of cable tunnels are more efficient, safe and reliable, reduce the risk of failures, and rationally allocate operation and maintenance resources to avoid resource waste.

The cable tunnel operation and maintenance integrated management method according to claim 3, characterized in that: Based on the trigger warning situation of D<0, the calculation formulas of the operation and maintenance resource allocation unit and the operation and maintenance efficiency evaluation unit are as follows: Operation and maintenance resource allocation unit: ; WS=WS s / WS m ; in: WG is the maintenance workload; WS is the maintenance speed coefficient; WS s is the current maintenance workload, WS s Indicates the amount of maintenance work completed per unit time; WS m Maintain workload for target, WS m Indicates the expected amount of maintenance work to be completed per unit time; TS max is the maximum total number of channels; The square root calculation can reduce the impact of load on operation and maintenance workload, and Can measure the relationship between load factor FX and maintenance speed; If WG>0, it means that the maintenance workload of the cable tunnel is large and requires more resources and time; If WG<0, it means that the maintenance workload is small and requires a small amount of resources and time; Evaluation unit for operation and maintenance effectiveness: ; in: X is the operation and maintenance efficiency value; The calculation reflects the resources required to maintain the overall operation and maintenance efficiency. When the maintenance workload WG is known, the overall efficiency is adjusted according to the size and load of the tunnel, as well as the operation and maintenance speed. The calculation is used to eliminate the negative impact caused by the increase in the number of channels; If X>0, it means that the overall operation and maintenance efficiency is high, and the cable tunnel maintenance efficiency is good, requiring short operation and maintenance time; If X<0, it means that the overall operation and maintenance efficiency is low and needs to be optimized.

6. The cable tunnel operation and maintenance integrated management method according to claim 5, characterized in that: Based on the trigger warning situation of D<0, there are two situations: D<0 and close to 0 and D<0 and far from 0. The specific analysis is as follows: When D < 0 and is close to 0, then WG < 0 and X > 0, which means that the cable tunnel load is close to the safety threshold but has not exceeded it. At this time, the maintenance workload WG tends to 0 and is negative, which means that the maintenance workload WG is low and does not require too many resources. The operation and maintenance efficiency value X is greater than 0, indicating that although the load is close, the operation and maintenance efficiency is high and the task can be completed in a short time. Adjustment measures: The load factor FX needs to be monitored and timely inspections arranged to avoid excessive load and system crash; When D < 0 and is far from 0, then WG > 0 and X < 0, indicating that the cable tunnel load is far below the safety threshold and the load is low. In this case, the maintenance workload WG is large, indicating that high maintenance workload and resources are required, but the operation and maintenance efficiency value X will be lower than 0, indicating low operation and maintenance efficiency. Adjustment measures: It is necessary to optimize resource utilization and adjust the maintenance speed factor WS.
