Description

Technical Field

[0001] This invention belongs to the field of electromechanical equipment maintenance technology, and in particular relates to a method and system for the maintenance and acceptance of escalators. Background Technology

[0002] As a key transportation device in urban rail transit, the operational safety and service life of escalators depend on regular maintenance. However, with the development of rail transit, the number of escalators in operation continues to increase, necessitating a batch assessment of maintenance quality to facilitate the acceptance of escalator maintenance.

[0003] Existing technologies monitor escalator status and output operational risk levels to assist in maintenance acceptance. However, these technologies neglect monitoring the maintenance process itself. Acceptance parties cannot determine whether maintenance personnel performed the work in the correct sequence or completed key maintenance steps within a reasonable timeframe. Furthermore, maintenance operations involving the timing of actions are difficult to trace and verify, leading to low efficiency in maintenance acceptance. Existing technologies deploy multiple sensors to comprehensively collect environmental parameters, equipment status parameters, and passenger flow data across the entire station, and use complex analysis algorithms to output operational risk levels or health indices. However, the core of maintenance acceptance lies in confirming the quality of a specific maintenance operation, not in predicting long-term risks to the escalator equipment. Existing technologies collect and process large amounts of status data with little correlation to maintenance actions, and the subsequent analysis of this data using complex algorithms significantly increases the time required from data collection to output results, failing to provide immediate support for maintenance acceptance and reducing its efficiency. Summary of the Invention

[0004] The present invention aims to provide a method and system for maintenance and acceptance of escalators, so as to solve the above-mentioned technical problems and improve the efficiency of maintenance and acceptance.

[0005] To address the aforementioned technical problems, this invention provides a method for the maintenance and acceptance of escalators, comprising the following steps: Obtain the maintenance operation list of the target escalator, and based on the maintenance operation list, obtain the maintenance operation process under the preset four-dimensional clustering ordering algorithm; Based on the aforementioned maintenance operation process, the number of maintenance items in the target escalator's maintenance list, the number of completed maintenance operations, the maintenance operation sequence with action time, and operational fault information are collected. Based on the number of items in the maintenance list and the number of completed maintenance tasks, a maintenance completion rate score is generated. Based on the operation time maintenance sequence, the actual maintenance duration sequence is obtained, and the deviation is calculated based on the actual maintenance duration sequence under the preset benchmark duration sequence to obtain the single maintenance duration deviation rate sequence. Based on the single maintenance duration deviation rate sequence and the action time maintenance operation sequence, a maintenance duration rationality score is generated under a preset rationality scoring algorithm; Based on the operational fault information, a health score is generated using a preset fault deduction algorithm; Based on the maintenance completion rate score, the maintenance duration reasonableness score, and the health score, a maintenance quality score is obtained under preset scoring weights, and maintenance acceptance is carried out based on the maintenance quality score.

[0006] In the above scheme, a standardized maintenance operation process is generated through a preset four-dimensional clustering ordination algorithm, providing a unified basis for subsequent maintenance data collection and maintenance quality scoring. Based on the maintenance operation process, this scheme calculates the maintenance completion rate score based on the number of maintenance checklist items and the number of completed maintenance operations. It obtains the actual maintenance duration based on the action time maintenance operation sequence and calculates the deviation from the preset benchmark duration sequence to generate a single-item maintenance duration deviation rate sequence. Then, a preset rationality scoring algorithm is used to obtain the maintenance duration rationality score, and a preset fault deduction algorithm is used to obtain the health score based on operational fault information. Therefore, compared to the traditional scheme that requires manual verification of maintenance progress item by item, this scheme can confirm the maintenance completion status through quantitative evaluation of the maintenance process, improving maintenance acceptance efficiency. Finally, this scheme generates a maintenance quality score by weighted fusion of the above three scores and uses the maintenance quality score as the basis for maintenance acceptance. While ensuring the objectivity of maintenance quality assessment, it greatly shortens the overall time from data collection to maintenance acceptance decision, improving the efficiency of maintenance acceptance.

[0007] Furthermore, the step of obtaining the maintenance operation list of the target escalator and, based on the maintenance operation list, obtaining the maintenance operation process under a preset four-dimensional clustering and ordering algorithm includes: obtaining the maintenance operation list of the target escalator, and obtaining the operating status, component removal type, structural location, and maintenance standard procedure for each maintenance operation from the maintenance operation list; sorting each maintenance operation in the maintenance operation list based on the operating status to obtain a first maintenance operation list; sorting each maintenance operation in the first maintenance operation list based on the component removal type to obtain a second maintenance operation list; sorting each maintenance operation in the second maintenance operation list based on the structural location to obtain a third maintenance operation list; sorting each maintenance operation in the third maintenance operation list based on the maintenance standard procedure to obtain a final maintenance operation list; and obtaining the maintenance operation process based on the final maintenance operation list.

[0008] The above solution sorts the maintenance task list layer by layer according to four dimensions: operational status, component removal type, structural location, and maintenance procedures. This effectively breaks down complex maintenance work into four interrelated dimensions, clarifying the sequence of maintenance tasks and ensuring a consistent and compliant maintenance process. Based on this maintenance process, the solution can specifically monitor the action time data for each task in the action time sequence to check for anomalies such as skipped steps or missing sequences, ensuring the reliability of the subsequently generated maintenance duration rationality score.

[0009] Further, obtaining the maintenance completion rate score based on the number of maintenance items in the maintenance list and the number of completed maintenance operations includes: obtaining the maintenance operation completion rate based on the number of maintenance items in the maintenance list and the number of completed maintenance operations; confirming that the maintenance operation completion rate is less than a preset maintenance completion qualification threshold, then obtaining a maintenance completion rate score set as the preset completion rate score lower limit; otherwise, performing a proportional conversion based on the maintenance operation completion rate to obtain the maintenance completion rate score.

[0010] In the above scheme, if the maintenance operation completion rate is less than the preset maintenance completion qualification threshold, it indicates that the maintenance operation of the target escalator is seriously substandard. Therefore, this scheme sets the maintenance completion rate score to the lowest value at this time. When the maintenance operation completion rate reaches the preset maintenance completion qualification threshold, this scheme converts the maintenance operation completion rate into a maintenance completion rate score in a proportional manner to accurately reflect the degree of maintenance operation completion and ensure the reliability of subsequent maintenance quality scores.

[0011] Further, the step of obtaining an actual maintenance duration sequence based on the action-time maintenance operation sequence, and calculating the deviation under a preset benchmark duration sequence based on the actual maintenance duration sequence to obtain a single maintenance duration deviation rate sequence, includes: obtaining a benchmark duration sequence based on the action-time maintenance operation sequence under a preset standard maintenance duration sequence; calculating the time difference based on the action-time maintenance operation sequence to obtain an actual maintenance duration sequence; calculating the deviation between the actual maintenance duration sequence and the benchmark duration sequence to obtain a maintenance duration deviation value sequence; and obtaining a single maintenance duration deviation rate sequence based on the maintenance duration deviation value sequence and the benchmark duration sequence; wherein each action-time maintenance operation in the action-time maintenance operation sequence has a corresponding single maintenance duration deviation rate in the single maintenance duration deviation rate sequence.

[0012] Furthermore, the step of obtaining a maintenance duration rationality score based on the single maintenance duration deviation rate sequence and the action time maintenance operation sequence, under a preset rationality scoring algorithm, includes: obtaining the action time maintenance operation quantity from the action time maintenance operation sequence; performing duration deviation processing steps for each single maintenance duration deviation rate in the single maintenance duration deviation rate sequence to obtain several deviation risks; performing cumulative superposition processing on the several deviation risks to obtain a cumulative deviation risk; and obtaining a maintenance duration rationality score based on the cumulative deviation risk and the action time maintenance operation quantity.

[0013] In the above scheme, the time deviation is calculated based on the actual maintenance time sequence and the benchmark time sequence to obtain a maintenance time deviation value sequence that can reflect abnormal maintenance operation time consumption. Based on this maintenance time deviation value sequence, this scheme obtains a single maintenance time deviation sequence corresponding to the maintenance operation with the action time. This single maintenance time deviation sequence can reflect whether the overall maintenance operation time is reasonable. Moreover, any single time deviation caused by misoperation or non-critical item disturbance will only be reflected in the corresponding single maintenance time deviation, and will not cause a large fluctuation in the subsequent overall maintenance time reasonableness score, so as to ensure the reliability of the maintenance time reasonableness score generated later.

[0014] Further, based on each individual maintenance duration deviation rate in the sequence of individual maintenance duration deviation rates, a duration deviation processing step is performed to obtain several deviation risks. The duration deviation processing step includes: confirming that the individual maintenance duration deviation rate is within a preset unreasonable range, then obtaining a deviation risk set as the upper limit of the preset deviation rate; otherwise, determining whether the individual maintenance duration deviation rate is within a preset reasonable range; confirming that the individual maintenance duration deviation rate is within the preset reasonable range, then obtaining a deviation risk set as the lower limit of the preset deviation rate; otherwise, using the absolute value of the individual maintenance duration deviation rate as the deviation risk.

[0015] Furthermore, the step of obtaining a health score based on the operational fault information under a preset fault deduction algorithm includes: obtaining a fault event sequence from the operational fault information; performing a fault deduction step on each fault event in the fault event sequence to obtain several fault deduction data; and obtaining a health score based on the several fault deduction data under a preset health score upper limit.

[0016] Furthermore, in the step of performing a fault deduction step for each fault event in the fault event sequence to obtain a plurality of fault deduction data, the fault deduction step includes: obtaining the fault type and fault equipment type from the fault event; obtaining a deduction score based on the fault type in a preset fault deduction library; obtaining a fault weight based on the fault equipment type in a preset component weight library; and obtaining fault deduction data based on the deduction score and the fault weight.

[0017] The above scheme obtains deduction scores from a preset fault deduction score library based on fault type. These deduction scores reflect the severity of the fault itself in the target escalator. Furthermore, it obtains fault weights from a preset component weight library based on fault equipment type. The deduction scores are then combined with the fault weights to calculate the fault deduction data. Specifically, the fault deduction data for the same type of fault in important components of the target escalator is larger, while the fault deduction data for the same type of fault in minor components is smaller. The resulting fault deduction data can more accurately reflect the degree of impact of the fault on the overall health status of the target escalator, making the generated health score more reliable.

[0018] This invention also provides an escalator maintenance and acceptance system for implementing any of the above-described escalator maintenance and acceptance methods, comprising: a maintenance operation process determination module for obtaining a maintenance operation list of the target escalator and obtaining a maintenance operation process based on the maintenance operation list using a preset four-dimensional clustering ordering algorithm; a maintenance process data acquisition module for acquiring, based on the maintenance operation process, the number of maintenance list items, the number of completed maintenance operation items, the action time maintenance operation sequence, and operational fault information of the target escalator; a maintenance completion rate scoring module for obtaining a maintenance completion rate score based on the number of maintenance list items and the number of completed maintenance operation items; and a single maintenance time deviation calculation module for calculating, based on the action time dimension... The system employs a maintenance operation sequence to obtain an actual maintenance duration sequence, and calculates the deviation based on this actual maintenance duration sequence under a preset baseline duration sequence to obtain a single-item maintenance duration deviation rate sequence. A maintenance duration rationality scoring module is used to obtain a maintenance duration rationality score based on the single-item maintenance duration deviation rate sequence and the action time maintenance operation sequence under a preset rationality scoring algorithm. A health score module is used to obtain a health score based on the operational fault information under a preset fault deduction algorithm. A maintenance acceptance module is used to obtain a maintenance quality score based on the maintenance completion rate score, the maintenance duration rationality score, and the health score under preset scoring weights, and to conduct maintenance acceptance based on the maintenance quality score.

[0019] Furthermore, the step of obtaining the maintenance operation list of the target escalator and, based on the maintenance operation list, obtaining the maintenance operation process under a preset four-dimensional clustering and ordering algorithm includes: obtaining the maintenance operation list of the target escalator, and obtaining the operating status, component removal type, structural location, and maintenance standard procedure for each maintenance operation from the maintenance operation list; sorting each maintenance operation in the maintenance operation list based on the operating status to obtain a first maintenance operation list; sorting each maintenance operation in the first maintenance operation list based on the component removal type to obtain a second maintenance operation list; sorting each maintenance operation in the second maintenance operation list based on the structural location to obtain a third maintenance operation list; sorting each maintenance operation in the third maintenance operation list based on the maintenance standard procedure to obtain a final maintenance operation list; and obtaining the maintenance operation process based on the final maintenance operation list.

[0020] In the above scheme, a standardized maintenance operation process is generated through a pre-set four-dimensional clustering ordination algorithm, providing a unified basis for subsequent maintenance data collection and maintenance quality scoring. Based on the maintenance operation process, this scheme calculates the maintenance completion rate score based on the number of maintenance checklist items and the number of completed maintenance operations. It obtains the actual maintenance duration based on the action time maintenance operation sequence and calculates the deviation from a pre-set baseline duration sequence to generate a single-item maintenance duration deviation rate sequence. Then, a pre-set rationality scoring algorithm is used to obtain the maintenance duration rationality score, and a health score is derived based on operational fault information using a pre-set fault deduction algorithm. This scheme can confirm the maintenance completion status through quantitative evaluation of the maintenance process, improving the efficiency of maintenance acceptance. Furthermore, by weightedly fusing the above three scores to generate a maintenance quality score, and using this quality score as the basis for maintenance acceptance, it can significantly shorten the overall time from data collection to maintenance acceptance decision while ensuring the objectivity of maintenance quality assessment, thus improving the efficiency of maintenance acceptance.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1 This embodiment provides a method for the maintenance and acceptance of escalators, including the following steps: Step S1: Obtain the maintenance work list of the target escalator, and obtain the maintenance work process based on the maintenance work list using a preset four-dimensional clustering ordering algorithm; Step S2: Based on the maintenance operation process, collect the number of maintenance items in the target escalator's maintenance list, the number of completed maintenance operations, the action time maintenance operation sequence, and operational fault information; Step S3: Generate a maintenance completion rate score based on the number of items in the maintenance list and the number of completed maintenance tasks; Step S4: Based on the operation time maintenance sequence, obtain the actual maintenance duration sequence, and calculate the deviation based on the actual maintenance duration sequence under the preset benchmark duration sequence to obtain the single maintenance duration deviation rate sequence; Step S5: Based on the single maintenance duration deviation rate sequence and the action time maintenance operation sequence, generate a maintenance duration rationality score under the preset rationality scoring algorithm; Step S6: Based on the operational fault information, generate a health score using a preset fault deduction algorithm; Step S7: Based on the maintenance completion rate score, the maintenance duration reasonableness score, and the health score, obtain the maintenance quality score under preset scoring weights, and conduct maintenance acceptance based on the maintenance quality score.

[0024] In the above embodiments, a standardized maintenance operation process is generated through a preset four-dimensional clustering ordination algorithm, providing a unified basis for subsequent maintenance data collection and maintenance quality scoring. Based on the maintenance operation process, this embodiment calculates the maintenance completion rate score based on the number of maintenance list items and the number of completed maintenance operations. The actual maintenance duration is obtained based on the action time maintenance operation sequence, and deviation calculation is performed between this sequence and a preset benchmark duration sequence to generate a single-item maintenance duration deviation rate sequence. A preset rationality scoring algorithm is then used to obtain a maintenance duration rationality score, and a health score is derived based on operational fault information using a preset fault deduction algorithm. Therefore, compared to traditional solutions that require manual verification of maintenance progress item by item, this embodiment can confirm maintenance completion status through quantitative evaluation of the maintenance process, improving maintenance acceptance efficiency. Finally, this embodiment generates a maintenance quality score by weighted fusion of the above three scores, and uses this score as the basis for maintenance acceptance. While ensuring the objectivity of maintenance quality assessment, this greatly shortens the overall time from data collection to maintenance acceptance decision, improving the efficiency of maintenance acceptance.

[0025] In one embodiment, maintenance quality scoring ,in, To score the maintenance completion rate, To score the reasonableness of the maintenance duration, The health rating is determined. If the maintenance quality rating S is 90≤S≤100, the existing maintenance process is maintained, and the current maintenance work is promoted as a benchmark case; if the maintenance quality rating S is 70≤S<90, the process for out-of-tolerance maintenance work items is optimized, and the time for inefficient maintenance work is shortened; if the maintenance quality rating S is S<70, the target escalator is immediately re-performed for maintenance.

[0026] Furthermore, the step of obtaining the maintenance operation list of the target escalator and, based on the maintenance operation list, obtaining the maintenance operation process under a preset four-dimensional clustering and ordering algorithm includes: obtaining the maintenance operation list of the target escalator, and obtaining the operating status, component removal type, structural location, and maintenance standard procedure for each maintenance operation from the maintenance operation list; sorting each maintenance operation in the maintenance operation list based on the operating status to obtain a first maintenance operation list; sorting each maintenance operation in the first maintenance operation list based on the component removal type to obtain a second maintenance operation list; sorting each maintenance operation in the second maintenance operation list based on the structural location to obtain a third maintenance operation list; sorting each maintenance operation in the third maintenance operation list based on the maintenance standard procedure to obtain a final maintenance operation list; and obtaining the maintenance operation process based on the final maintenance operation list.

[0027] In the above embodiments, the maintenance work list is sorted layer by layer according to four dimensions: operating status, component removal type, structural location, and maintenance procedures. This effectively decomposes complex maintenance work into four interrelated dimensions to clarify the sequence of maintenance tasks, ensuring a unified and compliant maintenance process. Based on the above maintenance work process, this embodiment can specifically monitor the action time data corresponding to each task in the action time maintenance work sequence for anomalies such as skipped steps or missing sequences, ensuring the reliability of the subsequently generated maintenance duration rationality score.

[0028] Further, obtaining the maintenance completion rate score based on the number of maintenance items in the maintenance list and the number of completed maintenance operations includes: obtaining the maintenance operation completion rate based on the number of maintenance items in the maintenance list and the number of completed maintenance operations; confirming that the maintenance operation completion rate is less than a preset maintenance completion qualification threshold, then obtaining a maintenance completion rate score set as the preset completion rate score lower limit; otherwise, performing a proportional conversion based on the maintenance operation completion rate to obtain the maintenance completion rate score.

[0029] In the above embodiments, if the maintenance operation completion rate is less than the preset maintenance completion qualification threshold, it indicates that the maintenance operation of the target escalator is seriously substandard. Therefore, in this embodiment, the maintenance completion rate score is set to the lowest value. When the maintenance operation completion rate reaches the preset maintenance completion qualification threshold, this embodiment converts the maintenance operation completion rate into a maintenance completion rate score in a proportional manner to accurately reflect the degree of maintenance operation completion and ensure the reliability of subsequent maintenance quality scores.

[0030] In one embodiment, maintenance work completion rate ,in, This represents the number of maintenance tasks that have been completed. The number of items on the maintenance list, and the maintenance completion rate score in this embodiment. 。 Further, the step of obtaining an actual maintenance duration sequence based on the action-time maintenance operation sequence, and calculating the deviation under a preset benchmark duration sequence based on the actual maintenance duration sequence to obtain a single maintenance duration deviation rate sequence, includes: obtaining a benchmark duration sequence based on the action-time maintenance operation sequence under a preset standard maintenance duration sequence; calculating the time difference based on the action-time maintenance operation sequence to obtain an actual maintenance duration sequence; calculating the deviation between the actual maintenance duration sequence and the benchmark duration sequence to obtain a maintenance duration deviation value sequence; and obtaining a single maintenance duration deviation rate sequence based on the maintenance duration deviation value sequence and the benchmark duration sequence; wherein each action-time maintenance operation in the action-time maintenance operation sequence has a corresponding single maintenance duration deviation rate in the single maintenance duration deviation rate sequence.

[0031] Furthermore, the step of obtaining a maintenance duration rationality score based on the single maintenance duration deviation rate sequence and the action time maintenance operation sequence, under a preset rationality scoring algorithm, includes: obtaining the action time maintenance operation quantity from the action time maintenance operation sequence; performing duration deviation processing steps for each single maintenance duration deviation rate in the single maintenance duration deviation rate sequence to obtain several deviation risks; performing cumulative superposition processing on the several deviation risks to obtain a cumulative deviation risk; and obtaining a maintenance duration rationality score based on the cumulative deviation risk and the action time maintenance operation quantity.

[0032] In the above embodiments, the time deviation is calculated based on the actual maintenance time sequence and the benchmark time sequence to obtain a maintenance time deviation value sequence that can reflect abnormal maintenance operation time consumption. Based on this maintenance time deviation value sequence, this embodiment obtains a single maintenance time deviation sequence corresponding to the maintenance operation with the action time. This single maintenance time deviation sequence can reflect whether the overall maintenance operation time is reasonable. Any single time deviation caused by misoperation or non-critical item disturbance will only be reflected in the corresponding single maintenance time deviation, and will not cause a large fluctuation in the subsequent overall maintenance time reasonableness score, so as to ensure the reliability of the maintenance time reasonableness score generated later.

[0033] Further, based on each individual maintenance duration deviation rate in the sequence of individual maintenance duration deviation rates, a duration deviation processing step is performed to obtain several deviation risks. The duration deviation processing step includes: confirming that the individual maintenance duration deviation rate is within a preset unreasonable range, then obtaining a deviation risk set as the upper limit of the preset deviation rate; otherwise, determining whether the individual maintenance duration deviation rate is within a preset reasonable range; confirming that the individual maintenance duration deviation rate is within the preset reasonable range, then obtaining a deviation risk set as the lower limit of the preset deviation rate; otherwise, using the absolute value of the individual maintenance duration deviation rate as the deviation risk.

[0034] In one embodiment, the number of maintenance list items There is a corresponding maintenance work set ,in, For the maintenance operation process, the first Each maintenance task has a pre-set standard maintenance duration set. ,and For maintenance work The corresponding standard maintenance duration.

[0035] In the above embodiments, the action-time maintenance operation sequence includes... Maintenance work during the operation period, and Furthermore, the action time set corresponding to each maintenance operation in the action time maintenance operation sequence. ,and This refers to the moment when the maintenance key is turned to the inspection mode. In this embodiment, from... arrive Preset reference duration for maintenance work The corresponding calculation formula is: Then targeting The baseline duration sequence for maintenance operations is as follows: Subsequently, the The actual maintenance time for each action-time maintenance operation The corresponding calculation formula is: The final actual maintenance duration sequence was obtained. .

[0036] In the above embodiment, the maintenance time deviation value corresponding to the i-th action time maintenance operation. Furthermore, the deviation rate of the single maintenance time corresponding to this maintenance operation. For each actual maintenance operation, the above calculation is performed to obtain the sequence of individual maintenance time deviation rates. Furthermore, the deviation risk corresponding to the maintenance operation for the i-th operation time is also calculated. The final maintenance duration reasonableness score will then be generated. .

[0037] Furthermore, the step of obtaining a health score based on the operational fault information under a preset fault deduction algorithm includes: obtaining a fault event sequence from the operational fault information; performing a fault deduction step on each fault event in the fault event sequence to obtain several fault deduction data; and obtaining a health score based on the several fault deduction data under a preset health score upper limit.

[0038] Furthermore, in the step of performing a fault deduction step for each fault event in the fault event sequence to obtain a plurality of fault deduction data, the fault deduction step includes: obtaining the fault type and fault equipment type from the fault event; obtaining a deduction score based on the fault type in a preset fault deduction library; obtaining a fault weight based on the fault equipment type in a preset component weight library; and obtaining fault deduction data based on the deduction score and the fault weight.

[0039] The above embodiments obtain deduction scores from a preset fault deduction score library based on fault type. These deduction scores reflect the severity of the fault in the target escalator. Furthermore, fault weights are obtained from a preset component weight library based on fault equipment type. The deduction scores are then combined with the fault weights to calculate the fault deduction data. Specifically, the fault deduction data for the same type of fault in important components of the target escalator is larger, while the fault deduction data for the same type of fault in minor components is smaller. The resulting fault deduction data can more accurately reflect the impact of the fault on the overall health status of the target escalator, making the generated health score more reliable.

[0040] In one embodiment, in a preset fault deduction library, if the fault type is a diagnostic warning or a control type III fault, the deduction score is 5; if the fault type is a diagnostic alarm, the deduction score is 10; if the fault type is a control type II fault, the deduction score is 20; and if the fault type is a control type I fault, the deduction score is 30. In a preset component weight library, if the faulty device type is a main unit, the fault weight is 25%; if the faulty device type is a handrail belt, the fault weight is 5%; if the faulty device type is a sprocket, the fault weight is 15%; if the faulty device type is a chain, the fault weight is 15%; if the faulty device type is a ladder step, the fault weight is 10%; if the faulty device type is a control system, the fault weight is 15%; and if the faulty device type is a safety switch, the fault weight is 10%.

[0041] In the above embodiments, health score ,in, The total number of fault events in the fault event sequence. This represents the deduction score corresponding to the i-th fault event. Let be the fault weight corresponding to the i-th fault event.

[0042] As an example, not a limitation, the maintenance task list is sorted using a four-dimensional clustering ordination algorithm. First, it is sorted by operational status: "Inspection Status → Normal Status". Then, it is sorted by component removal type: "No Removal → Removal of Cover Plate → Removal of Steps → Removal of Handrail → Removal of Handrail Belt". Next, it is sorted by structural location: "Upper Machine Room → Lower Machine Room → Upper End of Escalator → Lower End of Escalator → Middle Section of Escalator → Entire Escalator". Finally, it is sorted by maintenance procedure: "Safety Pre-inspection → Core Component Maintenance → Auxiliary Component Maintenance → Functional Testing → Resumption of Operation". The resulting maintenance task flow for the 12 tasks is as follows: The standard maintenance duration and baseline duration for each maintenance operation are as follows: As can be seen, the baseline duration sequence is .

[0043] Thus, the maintenance completion rate score is obtained. The sequence of deviation rates for single maintenance duration is as follows: And the reasonableness score of maintenance duration .

[0044] In this example, within the fault event sequence: the motor issues one warning, resulting in a deduction of 5 points and a fault weight of 25%; the sprocket issues one diagnostic alarm, resulting in a deduction of 10 points and a fault weight of 15%. Therefore, the health score is... .

[0045] Therefore, in this example, the maintenance quality score Therefore, if the maintenance quality score is 90≤S≤100, the maintenance acceptance action is to maintain the existing maintenance process and use this maintenance operation as a benchmark case for the same type of escalator.

[0046] Please see Figure 2 This embodiment also provides an escalator maintenance and acceptance system for implementing any of the above-described escalator maintenance and acceptance methods, including: a maintenance operation process determination module, used to obtain a maintenance operation list of the target escalator and obtain a maintenance operation process based on the maintenance operation list under a preset four-dimensional clustering ordering algorithm; a maintenance process data acquisition module, used to collect the number of maintenance list items, the number of completed maintenance operation items, the operation time maintenance operation sequence, and operational fault information of the target escalator based on the maintenance operation process; a maintenance completion rate scoring module, used to obtain a maintenance completion rate score based on the number of maintenance list items and the number of completed maintenance operation items; and a single maintenance time deviation calculation module, used to calculate the deviation based on the operation time...

A maintenance duration rationality scoring module is used to obtain a maintenance duration rationality score based on the single maintenance duration deviation rate sequence and the action time maintenance operation sequence under a preset rationality scoring algorithm. A health score module is used to obtain a health score based on the operational fault information under a preset fault deduction algorithm. A maintenance acceptance module is used to obtain a maintenance quality score based on the maintenance completion rate score, the maintenance duration rationality score, and the health score under preset scoring weights, and to conduct maintenance acceptance based on the maintenance quality score.

[0047] Furthermore, the step of obtaining the maintenance operation list of the target escalator and, based on the maintenance operation list, obtaining the maintenance operation process under a preset four-dimensional clustering and ordering algorithm includes: obtaining the maintenance operation list of the target escalator, and obtaining the operating status, component removal type, structural location, and maintenance standard procedure for each maintenance operation from the maintenance operation list; sorting each maintenance operation in the maintenance operation list based on the operating status to obtain a first maintenance operation list; sorting each maintenance operation in the first maintenance operation list based on the component removal type to obtain a second maintenance operation list; sorting each maintenance operation in the second maintenance operation list based on the structural location to obtain a third maintenance operation list; sorting each maintenance operation in the third maintenance operation list based on the maintenance standard procedure to obtain a final maintenance operation list; and obtaining the maintenance operation process based on the final maintenance operation list.

[0048] In the above embodiments, a standardized maintenance operation process is generated through a preset four-dimensional clustering ordination algorithm, providing a unified basis for subsequent maintenance data collection and maintenance quality scoring.
