Description

Technical Field

[0001] The present invention relates to the technical field of reducer assembly, and in particular to an intelligent assembly method and system for a planetary reducer. Background Art

[0002] In the field of mechanical manufacturing, planetary reducers, as a key transmission device, are widely used in many industries such as industrial automation, robotics, and aerospace. Through the combination of multi-stage planetary gear systems (reduction levels), they achieve the characteristics of large transmission ratio, high efficiency, and compact structure. The assembly process of planetary reducers is complex, involving the precise matching of multiple precision parts, and requires high assembly accuracy.

[0003] Existing planetary reducer assembly methods often rely on pre-established assembly process files for direct assembly. However, in the assembly process of multi-stage planetary reducers, the assembly error of each level will affect the assembly accuracy of subsequent levels. If the assembly error of a certain level is large, it will gradually accumulate to the next level, eventually leading to a decrease in the performance of the entire planetary reducer. Existing methods cannot be dynamically adjusted according to the actual assembly situation. Once the initial parameters are set improperly or the material properties change, the assembly quality is difficult to guarantee. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an intelligent assembly method and system for a planetary reducer, which can improve product quality, reduce production costs, and increase production efficiency.

[0024] Write detailed assembly process documents and mark each step with clear operation instructions and inspection standards;

[0025] Proofread, modify and improve assembly process documents.

[0026] Furthermore, the method for modifying the second assembly parameter set corresponding to the second deceleration level includes:

[0027] Based on the static and dynamic detection vectors corresponding to the first deceleration level, the assembly quality is evaluated to identify potential sources of error;

[0028] Based on the identified error sources, a correction strategy is developed to adjust the assembly parameters of the second deceleration level;

[0029] Based on the correction strategy, a corrected second assembly parameter set is obtained;

[0030] The corrected second assembly parameter set is recorded and stored.

[0031] Further, the above correction, assembly and assembly inspection process is repeated for the next deceleration level until all deceleration levels are assembled, including:

[0032] After completing the assembly and detection of the current deceleration level, the obtained dynamic and static detection vectors are compared and analyzed with the preset standards;

[0065] The present application is described below in conjunction with the drawings in the present application.

[0066] Embodiment 1: Figures 1 to 3 As shown, the intelligent assembly method of the planetary reducer of the present invention specifically includes the following steps:

[0067] S1. Obtain product assembly process information of the planetary reducer;

[0068] The method for obtaining product assembly process information of a planetary reducer includes:

[0069] Export relevant files from the design department or CAD system to ensure that all drawings and technical documents are the latest versions; obtain all design drawings and technical documents of the planetary reducer, including but not limited to 3D models, 2D engineering drawings, bills of materials, assembly sequence drawings, tolerance requirements, etc.;

[0070] Read and analyze the assembly process section in the technical documentation to extract key information, such as assembly sequence, tightening torque, lubrication requirements, etc.; understand the assembly process requirements of the planetary reducer in detail, including the assembly sequence of each component, the selection of assembly tools, the requirements of the assembly environment, etc.;

[0071] Combined with design drawings and technical documents, list all key parameters that affect assembly accuracy and determine their tolerance ranges; identify key parameters that affect assembly accuracy, such as gear meshing clearance, shaft concentricity, bearing preload, etc.;

[0072] Write detailed assembly process documents to ensure that each step has clear operating instructions and inspection standards; Based on the information collected, develop preliminary assembly process documents, including assembly process, required tools, inspection methods, etc.;

[0073] Communicate with design, quality, production and other departments to proofread, modify and improve assembly process documents, confirm whether the contents of assembly process documents meet actual needs; ensure the accuracy and feasibility of assembly process documents to avoid omissions or errors.

[0074] In this step, by exporting the latest version of drawings and technical documents from the design department or CAD system, the timeliness and accuracy of the information obtained are guaranteed; all relevant design drawings and technical documents are collected and read to ensure the comprehensiveness and completeness of the information; the assembly process part of the technical documents is deeply analyzed, and key information such as assembly sequence, tightening torque, lubrication requirements, etc. are extracted to provide clear guidance for the subsequent assembly process; the key parameters affecting the assembly accuracy are identified to provide an important basis for quality control in the assembly process; based on the collected information, detailed assembly process documents are compiled to provide clear operating guidelines for assemblers; the assembly process documents are proofread and improved, The accuracy and feasibility of the documents are ensured; the detailed assembly process documents provide assemblers with clear operating steps and inspection standards, reducing errors and omissions in the assembly process and improving assembly efficiency; through strict control of key parameters, the assembly accuracy of the planetary reducer is ensured, and the overall quality and performance of the product are improved; accurate assembly process information provides a reliable foundation for subsequent reduction level division, assembly inspection, and parameter correction steps, ensuring the smooth progress of the entire intelligent assembly process; the S1 step ensures the accuracy and completeness of the assembly information, provides strong support for subsequent assembly work, improves assembly efficiency and quality, and provides a guarantee for the overall performance of the product.

[0075] S2. According to the product assembly process information, the planetary reducer is divided into reduction levels, and each gear in the planetary reducer is divided into corresponding reduction levels; the reduction levels correspond to a set of planetary gear systems, and the planetary reducer has at least two reduction levels;

[0076] The principles for dividing the reduction levels of planetary reducers include:

[0077] Transmission ratio requirements: Planetary reducers achieve large transmission ratios through the combination of multi-stage planetary gear systems; therefore, the division of reduction levels must first meet the transmission ratio requirements; the design department determines the total transmission ratio and the distribution between each level based on the application and transmission requirements; based on these requirements, the planetary reducer is divided into several reduction levels, each level corresponds to a set of planetary gear systems, and the required transmission ratio is achieved through the combination of different levels;

[0078] Carrying capacity: Each reduction level needs to bear a certain torque and load; therefore, when dividing the reduction levels, the carrying capacity of each gear needs to be considered; usually, gears with larger carrying capacity will be arranged at the level close to the input end to bear greater torque; while gears with smaller carrying capacity will be arranged at the level close to the output end to reduce the impact on the entire reducer;

[0079] Gear size and fit: The gear system of the planetary reducer involves the precise fit of multiple precision parts. When dividing the reduction levels, the size and fit of the gears need to be considered. For example, there needs to be a certain meshing clearance between the gears of adjacent levels to ensure the smooth operation of the gear system. At the same time, the fit between the gears and parts such as shafts and bearings also needs to be considered to ensure assembly accuracy and performance.

[0080] Assembly process requirements: The division of deceleration levels also needs to consider assembly sequence and process requirements; a reasonable assembly sequence can reduce the accumulation of assembly errors and improve assembly accuracy; at the same time, factors such as tools, fixtures and testing equipment required in the assembly process also need to be considered to ensure the smooth progress of the assembly process;

[0081] Material properties: Gears of different levels may use different materials and heat treatment processes; when dividing the reduction levels, it is necessary to consider the material properties and heat treatment requirements; for example, some materials may have better wear resistance and fatigue resistance, suitable for the level that bears greater loads; while some materials may have better processing performance and cost-effectiveness, suitable for other levels;

[0082] In-depth understanding of the overall structure of the planetary reducer and the functions of each component;

[0083] The planetary reducer is divided into multiple reduction levels, each level corresponds to a set of planetary gear systems;

[0084] Determine the position and function of each gear in the planetary reducer according to the design drawings and technical documents;

[0085] Combined with the assembly process file, determine the assembly sequence of each deceleration level;

[0086] Combine design drawings and technical documents to list the key parameters of each deceleration level to ensure assembly accuracy;

[0087] The division results and key parameters of each deceleration level are recorded in the assembly process file.

[0088] In this step, the planetary reducer is divided into multiple levels by accurately dividing the reduction levels and according to the transmission ratio requirements determined by the design department, and each level corresponds to a planetary gear system; it is ensured that the required transmission ratio can be achieved through the combination of different levels, so as to meet the transmission requirements of various applications; when dividing the reduction levels, the load-bearing capacity of the gears at each level is fully considered, and the gears with larger load-bearing capacity are arranged at the level close to the input end to withstand greater torque; this not only improves the overall load-bearing capacity of the reducer, but also reduces the risk of failure caused by excessive load; the gear system of the planetary reducer involves the precise matching of multiple precision parts; by reasonably dividing the reduction levels and considering the size and matching relationship of the gears, it can be ensured that there is appropriate meshing clearance between the gears of adjacent levels, as well as the precise matching of the gears with shafts, bearings and other parts; It helps to improve the smooth operation performance and assembly accuracy of the gear system; the division of reduction levels also needs to consider the assembly sequence and process requirements; through reasonable assembly sequence and process planning, the accumulation of assembly errors can be reduced and the assembly accuracy can be improved; at the same time, the use of tools, fixtures and testing equipment in the assembly process can be optimized, thereby improving assembly efficiency; gears of different levels may use different materials and heat treatment processes; by reasonably dividing the reduction levels and considering material properties and heat treatment requirements, the advantages of various materials can be fully utilized, which helps to reduce manufacturing costs and improve the overall performance and reliability of the reducer; recording the division results and key parameters of each reduction level in the assembly process file is helpful for recording and management in the subsequent assembly process; it can ensure that each step in the assembly process meets the design requirements and improves assembly quality and traceability.

[0089] S3, after the first deceleration level is assembled, perform assembly inspection to obtain the dynamic and static inspection vectors corresponding to the first deceleration level;

[0090] Extract the assembly parameter set corresponding to each reduction level from the product assembly process information of the planetary reducer; the assembly parameter set includes shaft coaxiality, bearing preload, assembly temperature and lubrication method; for the first reduction level, we need to sort out the first assembly parameter set according to the relevant requirements in the product assembly process information; these parameters will guide the assembly process of the first reduction level to ensure the accuracy and reliability of the assembly;

[0091] Based on the extracted first assembly parameter set, the first reduction level is assembled; during the assembly process, each assembly step needs to be strictly controlled to ensure the precise positioning and tight fit of parts such as gears, shafts, and bearings; during the assembly process, the assembly quality is monitored in real time to ensure that the assembly accuracy meets the design requirements;

[0092] After the assembly is completed, the assembly is dynamically tested; the dynamic test includes the meshing condition of the gears, running stability, vibration and noise, etc.; the performance of the first reduction level under the dynamic working state is evaluated; the dynamic test results include vibration frequency, noise decibel, axial runout and radial runout; the static test mainly focuses on the detection of the geometric dimensions, assembly clearance, meshing marks, etc. of the assembly; the assembly accuracy and reliability of the first reduction level under the static state are evaluated; the static test results include backlash error value, center distance error value and gear parallelism error value;

[0093] In order to quantitatively evaluate the dynamic detection results, a dynamic detection assembly evaluation model is introduced; this model is based on machine learning or deep learning technology. By analyzing and learning a large amount of dynamic detection data, it can automatically evaluate the performance of the first deceleration level under dynamic working conditions and give a dynamic detection score;

[0094] A static inspection assembly evaluation model is introduced to quantitatively evaluate the static inspection results. This model is based on machine learning or deep learning technology. By analyzing and learning a large amount of static inspection data, it can automatically evaluate the assembly accuracy and reliability of the first deceleration level in a static state and give a static inspection score.

[0095] The dynamic detection score and the static detection score are combined to obtain the dynamic and static detection vectors corresponding to the first deceleration level; the dynamic and static detection vectors corresponding to the first deceleration level not only include the performance evaluation results of the first deceleration level under dynamic and static states, but also reflect the quality control situation during the assembly process.

[0096] In this step, by extracting the assembly parameter set corresponding to each reduction level from the product assembly process information, especially sorting out a detailed first assembly parameter set for the first reduction level, accurate guidance is provided for the assembly process; the precise positioning and tight fit of parts such as gears, shafts, and bearings are ensured, thereby improving the accuracy of assembly; during the assembly process, the assembly quality is monitored in real time to ensure that the assembly accuracy meets the design requirements; it helps to promptly discover and correct errors in the assembly process to avoid the impact of error accumulation on the assembly accuracy of subsequent levels; a comprehensive evaluation of the assembly of the first reduction level is carried out by combining dynamic detection and static detection; dynamic detection focuses on the meshing condition of gears, running smoothness, vibration and noise, while static detection focuses on the meshing condition of gears, running smoothness, vibration and noise, etc. The inspection focuses on the geometric dimensions, assembly clearances, meshing marks, etc. of the assembly. It helps to accurately understand the performance of the first reduction level under dynamic and static conditions. It introduces dynamic inspection assembly evaluation models and static inspection assembly evaluation models to quantitatively evaluate the inspection results. It can automatically evaluate the performance of the first reduction level and give a corresponding score. This quantitative evaluation method makes the evaluation results more objective and accurate, which helps to adjust and optimize the assembly parameters of subsequent levels. The dynamic and static inspection vectors obtained not only include the performance evaluation results of the first reduction level under dynamic and static conditions, but also reflect the quality control situation during the assembly process. This provides an important reference basis for the assembly of subsequent levels and helps to optimize the assembly quality and performance of the entire planetary reducer.

[0097] S4, considering the static and dynamic detection vectors corresponding to the first deceleration level, performing parameter correction on the second assembly parameter set corresponding to the second deceleration level to obtain a corrected second assembly parameter set;

[0098] The method for modifying the parameters of the second assembly parameter set corresponding to the second deceleration level includes:

[0099] Based on the dynamic and static test results of the first reduction level, the assembly quality is evaluated and potential error sources are found; the vibration frequency, noise decibel, axial runout and radial runout are analyzed to determine the performance of the first reduction level under dynamic working conditions; the backlash error value, center distance error value and gear parallelism error value are analyzed to evaluate the assembly accuracy of the first reduction level under static conditions; the dynamic and static test vectors of the first reduction level are generated by combining the dynamic test scores and the static test scores to comprehensively evaluate the assembly quality of the first reduction level;

[0100] By analyzing the dynamic and static detection vectors, the key parameters that may cause errors are identified, and the main error sources in the first deceleration level assembly process are determined, providing a basis for subsequent parameter correction;

[0101] According to the identified error sources, formulate corresponding correction strategies and adjust the assembly parameters of the second deceleration level; according to the error situation of the first deceleration level, take compensation measures to reduce the impact of the error on subsequent levels;

[0102] Based on the correction strategy, a new second assembly parameter set is generated to ensure the assembly accuracy of the second deceleration level; the adjusted parameters are updated to the second assembly parameter set to ensure that each parameter meets the new requirements; the corrected second assembly parameter set is verified to ensure the rationality and feasibility of the parameters;

[0103] The corrected second assembly parameter set is recorded for reference and verification in subsequent steps.

[0104] In this step, by carefully analyzing the dynamic and static detection results of the first deceleration level, the potential and main error sources can be accurately identified; this provides a scientific basis for the subsequent correction of the assembly parameters of the second deceleration level, which helps to reduce assembly errors and improve the assembly accuracy of the second deceleration level; based on the analysis results of the dynamic and static detection vectors, a targeted correction strategy can be formulated to adjust the assembly parameters of the second deceleration level; it not only takes into account the performance under dynamic working conditions, but also takes into account the assembly accuracy under static conditions, so as to comprehensively optimize the assembly performance of the second deceleration level; the parameter correction method in this step makes the assembly process more flexible and adjustable; once the first deceleration level is identified Assembly errors can immediately correct the assembly parameters of the second reduction level, avoiding the accumulation and transmission of errors, and improving the controllability and stability of the entire planetary reducer assembly process; by correcting the assembly parameters of the second reduction level, it can ensure that each reduction level can meet the expected assembly quality and performance requirements; it helps to improve the product quality and reliability of the entire planetary reducer, extend its service life, and reduce maintenance costs; the implementation of this step depends on the in-depth analysis of dynamic and static detection vectors and the formulation of intelligent correction strategies; this promotes the intelligent development of the planetary reducer assembly process, improves assembly efficiency and accuracy, and provides strong support for the intelligent transformation in the field of mechanical manufacturing.

[0105] S5, assembling the second deceleration level based on the corrected second assembly parameter set, and performing assembly detection after the assembly is completed to obtain a dynamic and static detection vector corresponding to the second deceleration level;

[0106] Before assembling the second deceleration level, ensure that all related parts and components are ready and meet the requirements of the revised second assembly parameter set; check the size, shape, material and surface treatment of the parts to ensure that they meet the assembly standards;

[0107] Following the revised second assembly parameter set, the gears, bearings, shafts and other parts of the second reduction level are assembled accurately. During the assembly process, special attention is paid to the matching clearance, positioning accuracy and tightening torque of the parts to ensure the accuracy and stability of the assembly.

[0108] After the second deceleration level is assembled, the assembly is inspected to verify the assembly quality and accuracy. The dynamic and static detection vectors are important indicators for evaluating the performance of the assembly, including dimensional accuracy and position accuracy in static conditions, as well as vibration and noise in dynamic conditions.

[0109] Static testing includes:

[0110] Dimension and shape accuracy detection: Use high-precision measuring tools to measure the dimensions of each key part of the second reduction level, including the gear pitch, tooth height, tooth width, and the hole diameter and shaft diameter of the shaft and bearing seat;

[0111] Fit clearance detection: Use tools such as feeler gauges and micrometers to detect the fit clearance between gears, bearings, shafts, housings and other components to ensure that the tightness after assembly is appropriate to avoid poor operation or increased wear caused by over-tightening or over-loosening;

[0112] Position accuracy detection: detect the relative position accuracy between the components through positioning pins, reference surfaces, etc. to ensure that the assembled planetary reducer can maintain a stable transmission relationship during operation;

[0113] Dynamic detection includes:

[0114] Vibration detection: Install a vibration sensor on the assembled second reduction stage to collect vibration signals during operation, analyze the vibration conditions of gear meshing, bearing operation and other parts, determine whether there is abnormal vibration, and then evaluate the assembly quality and accuracy;

[0115] Noise detection: Use a noise meter or acoustic analyzer to detect the noise of the second reduction stage in operation, and identify the source and nature of the noise by analyzing the noise spectrum;

[0116] Temperature detection: Use temperature sensors to monitor the temperature changes of various components during operation, especially the temperature of gears, bearings and other easily worn parts, to detect overheating in time and prevent wear and damage caused by poor lubrication or over-tight assembly.

[0117] In this step, by following the revised second assembly parameter set, this step ensures the precise assembly of various gears, bearings, shafts and other parts in the second reduction level; this not only improves the assembly accuracy, but also enhances the stability of the assembly, providing a strong guarantee for the overall performance of the planetary reducer; during the assembly process, this step pays special attention to key factors such as the fitting clearance, positioning accuracy and tightening torque of the parts; by precisely controlling these factors, it effectively avoids poor operation or increased wear caused by problems such as too tight or too loose fitting, inaccurate positioning, etc., thereby extending the service life of the planetary reducer; this step evaluates the assembly quality of the second reduction level by combining static and dynamic testing. Comprehensive evaluation; static testing includes size and shape accuracy testing, fit clearance testing and position accuracy testing, while dynamic testing covers vibration testing, noise testing and temperature testing; ensuring that the assembly meets the design requirements both statically and dynamically; during the assembly inspection process, this step can promptly discover problems in the assembly, and by promptly analyzing the causes of the problems and taking corresponding measures to adjust or rework, it effectively avoids the accumulation and expansion of problems and ensures the overall performance and quality of the planetary reducer; this step not only improves the assembly accuracy and stability, but also optimizes the fit clearance and positioning accuracy, comprehensively evaluates the assembly quality, and promptly discovers and solves problems, while improving assembly efficiency and intelligence.

[0118] S6. Repeat the above correction, assembly and assembly inspection process for the next deceleration level until all deceleration levels are assembled, including:

[0119] After completing the assembly and detection of the current deceleration level, the obtained dynamic and static detection vectors are compared and analyzed with the preset standards;

[0120] Based on the results of the comparative analysis, the assembly errors existing at the current level are identified;

[0121] Based on the identified problems, the assembly parameter set of the next reduction level is modified accordingly; the modification process involves multiple aspects such as gear meshing clearance, bearing preload, shaft parallelism and perpendicularity, etc.

[0122] Use the revised assembly parameter set to assemble the next deceleration level;

[0123] During assembly, ensure that all parts and components fit precisely according to revised parameters;

[0124] Use advanced assembly techniques and tools, such as precision measuring equipment, automated assembly systems, etc., to ensure assembly accuracy and efficiency;

[0125] Assembly inspection:

[0126] After the assembly of the next deceleration level is completed, the assembly is inspected immediately; high-precision measuring equipment and sensors, such as laser rangefinders, vibration sensors, noise meters, etc., are used to obtain accurate inspection results;

[0127] Compare and analyze the test results of the next deceleration level with the preset standards;

[0128] If the test results meet the preset requirements, the same correction, assembly and testing process will be continued for the next deceleration level; otherwise, the assembly parameters will be further corrected according to the analysis results, and the assembly and testing will be carried out again;

[0129] The iteration process continues until all deceleration levels are assembled and the inspection results of each level meet the preset requirements.

[0130] In this step, through continuous iterative correction, assembly and detection processes, assembly errors can be gradually eliminated and the assembly accuracy of each reduction level can be improved; at the same time, this iterative process also ensures the consistency of assembly of all reduction levels, avoiding the overall performance degradation caused by the accumulation of assembly errors between levels; in the iterative process, this step dynamically corrects the assembly parameters according to the detection results, so that the assembly parameters are more in line with the actual assembly requirements; the optimized assembly parameters can improve the overall performance of the planetary reducer, reduce vibration, reduce noise, improve transmission efficiency, etc.; this step improves the flexibility and intelligence level of the assembly process through intelligent assembly methods and tools; the intelligent assembly method can dynamically correct the assembly parameters according to the real-time detection results Dynamic adjustment ensures the efficiency and accuracy of the assembly process; through iterative correction and automation and intelligence of the detection process, this step can significantly improve production efficiency and reduce production costs; at the same time, precise assembly also reduces rework and repair costs caused by assembly errors, further reducing the total cost; precise assembly and detection processes ensure that the planetary reducer can maintain stability and reliability during operation; it not only increases the service life of the product, but also enhances customer trust and satisfaction with the product; this step improves assembly accuracy and consistency, optimizes assembly parameters and improves product performance, enhances the flexibility and intelligence of the assembly process, improves production efficiency and reduces costs, and improves product quality and reliability.

[0131] Embodiment 2: Figure 4 As shown, the intelligent assembly system of the planetary reducer of the present invention specifically includes the following modules:

[0132] Process information acquisition module, which acquires product assembly process information of planetary reducer;

[0133] A reduction level division module divides the planetary reducer into reduction levels according to the product assembly process information, and divides each gear in the planetary reducer into corresponding reduction levels; the reduction level corresponds to a set of planetary gear systems, and the planetary reducer has at least two reduction levels;

[0134] An assembly detection module performs assembly detection after the first deceleration level is assembled, and obtains the dynamic and static detection vectors corresponding to the first deceleration level;

[0135] A parameter correction module, considering the static and dynamic detection vectors corresponding to the first deceleration level, performs parameter correction on the second assembly parameter set corresponding to the second deceleration level, and obtains a corrected second assembly parameter set;

[0136] A second deceleration level assembly detection module assembles the second deceleration level based on the revised second assembly parameter set, and performs assembly detection after the assembly is completed to obtain a dynamic and static detection vector corresponding to the second deceleration level;

[0137] The subsequent deceleration level assembly module repeats the above correction, assembly and assembly detection process for the next deceleration level until all deceleration levels are assembled.

[0138] According to the actual assembly situation, the system can obtain the dynamic and static detection vectors of each level through the assembly detection module, and then dynamically adjust the assembly parameters of the next level through the parameter correction module; it can effectively avoid the accumulation of assembly errors and ensure that each level can achieve the expected assembly accuracy;

[0139] Through the intelligent assembly process, the system can automatically complete the division of deceleration levels, the correction of assembly parameters and the detection of assemblies, which greatly reduces the reliance on manual operations and improves assembly efficiency. At the same time, since assembly errors can be detected and corrected in real time, the assembly quality has also been significantly improved.

[0140] The system can cope with the assembly requirements of planetary reducers of different models and specifications. It obtains the corresponding assembly process information through the process information acquisition module, and divides the reduction level and sets the assembly parameters accordingly. This enables the system to be widely used in industrial automation, robotics, aerospace and other industries.

[0141] Since the system can ensure the assembly accuracy at each level, the failure rate of the planetary reducer caused by assembly errors is reduced; at the same time, the intelligent assembly process also reduces the dependence on manual operation and reduces assembly quality problems caused by human errors, thereby reducing subsequent maintenance costs;

[0142] The system can record and store assembly parameters, test results and other information at each level, achieving data traceability; it helps to manage the assembly process intelligently, optimize the assembly process, and improve assembly efficiency and quality;

[0143] In summary, the intelligent assembly system of the planetary reducer effectively solves the problems existing in the existing planetary reducer assembly process by dynamically adjusting assembly parameters, improving assembly efficiency and quality, enhancing adaptability, reducing failure rate and maintenance costs, and realizing data traceability and intelligent management.
