[0007] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0008] One embodiment of the present invention provides a method for evaluating the operating efficiency of electromechanical equipment, the method comprising: Collect equipment operation data and equipment performance data of each electromechanical equipment to be evaluated for operation performance, perform preliminary classification and reclassification to obtain sub-category operation data of category operation data and sub-category performance data of category performance data; Perform performance ratio analysis on sub-category performance data to obtain sub-category operation energy efficiency ratios, perform performance ratio analysis on category performance data to obtain category operation efficiency ratios, set actual performance weight data based on equipment operation data and category operation data, and then obtain category target performance data, and then obtain performance gap ratios for preset operation data categories; Obtain equipment performance gap ratio, conduct performance comparison analysis and judgment based on the equipment performance gap ratio, and obtain performance status judgment information of electromechanical equipment; Perform single-machine operation efficiency analysis and linkage operation efficiency analysis on electromechanical equipment, and then obtain the equipment single-machine linkage efficiency judgment information, such as Figure 1 shown.

[0009] The working principle and technical effect of the above technical solution are as follows: the equipment operation data and equipment efficiency data of each electromechanical equipment for operation efficiency evaluation are collected, and preliminary classification and reclassification are performed to obtain sub-category operation data of the category operation data and sub-category efficiency data of the category efficiency data; by refining and refining the equipment, in-depth data efficiency analysis of the electromechanical equipment can be achieved, improving the accuracy and comprehensiveness of the efficiency analysis.

Through efficiency ratio analysis, the efficiency contribution of each category and subcategory in the overall electromechanical equipment can be obtained, and the efficiency analysis of the weights of categories and subcategories can be further obtained, which simplifies the complexity of efficiency calculation, realizes the differentiation of efficiency analysis complexity, and improves task completion.

[0010] Actual performance weight data is set based on equipment operation data and category operation data, thereby obtaining category target performance data and then obtaining the performance gap ratio of the preset operation data category. The actual performance weight data set based on the category performance ratio is more closely aligned with the performance characteristics of the category, allowing higher performance categories to be assigned more weights, thereby optimizing the performance of electromechanical equipment and enhancing its performance. Obtain the equipment efficiency gap ratio, conduct efficiency comparison analysis and judgment based on the equipment efficiency gap ratio, and obtain efficiency status judgment information of the electromechanical equipment; by obtaining the equipment efficiency gap ratio to accurately quantify the efficiency of the equipment, the operating efficiency of the electromechanical equipment can be efficiently obtained; Perform stand-alone and linkage performance analysis on electromechanical equipment to obtain information on the equipment's stand-alone and linkage performance. This allows for targeted analysis of different electromechanical equipment operating scenarios, enabling accurate assessment of both stand-alone and linkage performance.

[0011] In one embodiment of the present invention, the collecting of equipment operation data and equipment performance data of each electromechanical equipment for operation performance evaluation, and performing preliminary classification and reclassification to obtain sub-category operation data of the category operation data and sub-category performance data of the category performance data, includes: Acquire information of electromechanical equipment requiring operational performance evaluation, classify the electromechanical equipment information according to preset electromechanical equipment categories, and obtain category equipment information; Collect operation data of each electromechanical device in the category equipment information to obtain equipment operation data; obtaining the current performance of the electromechanical equipment according to the operating data of the electromechanical equipment, and obtaining equipment performance data; Classify the equipment operation data according to the preset operation data types to obtain category operation data; Reclassify each category of operating data to obtain subcategory operating data; Classify the current performance of the equipment according to the preset operating data types to obtain category performance data; Each category performance data is reclassified to obtain subcategory performance data.

[0012] The working principle and technical effects of the above technical solution are as follows: obtaining the information of electromechanical equipment that needs to be evaluated for operational performance, classifying the electromechanical equipment information according to the preset electromechanical equipment types, and obtaining category equipment information; the electromechanical equipment that needs to be evaluated for operational performance is the target evaluation equipment (which may include multiple equipment of multiple types), and the preset electromechanical equipment types include rotating machinery (industrial motors and wind turbines, etc.), power transmission (industrial gearboxes and automobile gearboxes, etc.), fluid machinery (centrifugal compressors and hydraulic pumps, etc.) and power equipment (transformers and inverters, etc.).

[0013] Collect operation data of each electromechanical device in the category equipment information to obtain equipment operation data; The current performance of the electromechanical equipment is obtained based on the operating data of the electromechanical equipment to obtain equipment performance data. The equipment operating data includes energy consumption data, production capacity data, status data, and environmental data. The equipment performance data includes energy consumption health data, production capacity health data, status health data, and environmental health data. The health data is the effective output energy divided by the work divided by the total input energy multiplied by 100%. The equipment performance data is the sum of all sub-categories of health data.

[0014] Classify the equipment operation data according to the preset operation data types to obtain category operation data; Reclassify each category of operating data to obtain subcategory operating data; the subcategory operating data includes energy consumption data (such as power consumption, fuel consumption, and efficiency ratio), production data (such as acquired energy and output efficiency), status data (such as abnormal temperature data and abnormal noise data), and environmental data (such as temperature and humidity data, load data, and operating time); By classifying the operating data of electromechanical equipment into categories and subcategories, it is possible to perform detailed operation analysis of the electromechanical equipment, obtain targeted operation data for each category and subcategory, and improve the pertinence and efficiency of data processing.

[0015] Classify the current performance of the equipment according to the preset operating data types to obtain category performance data; Reclassify each category of performance data to obtain subcategory performance data; the subcategory performance data includes electricity consumption health data and fuel consumption health data of energy consumption data, energy acquisition health data and output efficiency health data of production capacity data, health data of temperature anomaly data and noise anomaly data of status data, and health data of temperature and humidity, load health data and operating time health data of environmental data. The health data is the effective output energy of each subcategory performance data divided by the work divided by the total input energy multiplied by 100%).

[0016] By classifying the performance data of electromechanical equipment into categories and subcategories, it is possible to perform detailed performance analysis of the equipment, obtain targeted performance for each category and subcategory, and improve the pertinence and efficiency of data processing.

[0017] In one embodiment of the present invention, performing performance ratio analysis on subcategory performance data to obtain subcategory operation performance ratios and performing performance ratio analysis on category performance data to obtain category operation performance ratios include: Matching the subcategory operating data and subcategory performance data of the same subcategory of the same preset operating data type to obtain the subcategory performance data corresponding to each subcategory operating data; Obtain the proportion of the subcategory performance data corresponding to each subcategory's operating data in the category performance data corresponding to the subcategory, and obtain the subcategory operating efficiency ratio; The proportion of the category performance data corresponding to the category operation data of the preset operation data type in the device performance data is obtained to obtain the category operation performance ratio.

[0018] The working principle and technical effects of the above technical solution are as follows: the subcategory operation data and subcategory performance data of the same subcategory of the same preset operation data type are matched to obtain the subcategory performance data corresponding to each subcategory operation data; by matching operation and performance, the performance data caused by the operation data is obtained, thereby improving the accuracy and pertinence of performance acquisition; The proportion of the subcategory performance data corresponding to each subcategory operating data in the category performance data corresponding to the subcategory is obtained to obtain the subcategory operating efficiency ratio; the equipment efficiency data is specifically understood to be the sum of the subcategory performance data corresponding to all subcategory operating data of all preset operating data types; by obtaining the proportion of the subcategory performance data in the category performance data corresponding to the subcategory, the degree of contribution of the subcategory performance to the category performance is realized, and the performance of each subcategory is evaluated.

[0019] The proportion of the category performance data corresponding to the category operating data of the preset operating data category (i.e., the sum of the subcategory performance data of all subcategory operating data within the preset operating data category) in the device performance data is obtained to obtain the category operating performance ratio. By obtaining the proportion of category performance data in the device performance data, the contribution of category performance to device performance is determined, and the performance of each category is evaluated.

[0020] When the equipment operation data = 0 or the category performance data = 0, the flag is invalid.

[0021] In one embodiment of the present invention, the step of setting actual performance weight data based on the device operation data and the category operation data, thereby obtaining category target performance data, and then obtaining the performance gap ratio of the preset operation data category includes: Calculate actual performance weight data of preset operating data types corresponding to the category performance data based on category operating data and equipment operating data; The calculation formula of the actual effectiveness weight data is:

[0022] Among them, XQ is the actual efficiency weight data, LY is the category operation data, SY is the equipment operation data, and XX is the efficiency density correction coefficient; The calculation formula of the efficiency density correction coefficient is:

[0023] Where LX is the category performance data, LY is the category operation data, SY is the equipment operation data, SX is the equipment performance data, and β is the performance density correction coefficient. A value of 0.2 to 0.5 is recommended to balance the contributions of operation data and performance data and ensure that XQ does not completely offset the impact of operation data. The smaller the value, the greater the impact of the operation data ratio.

[0024] Through the efficiency density correction coefficient, the impact of the conversion analysis between operation and efficiency is minimized, the underestimation of high-efficiency equipment is avoided, the corresponding efficiency weight is obtained through operation, and the accuracy of weight calculation is improved.

[0025] The category performance data divided by the category operation data can obtain the category performance density, the equipment performance data divided by the equipment operation data can obtain the average performance density, and the category performance density divided by the average performance density can obtain the performance density correction coefficient.

[0026] Multiplying the equipment performance data by the actual performance weight data to obtain target performance data of a category corresponding to a preset operating data category corresponding to the actual performance weight data; Calculate the ratio of the category performance data corresponding to the preset operating data type to the category target performance data to obtain the performance gap ratio of the preset operating data type; Through performance gap comparison, preliminary performance analysis of electromechanical equipment is carried out to obtain performance status determination information.

[0027] The working principle and technical effect of the above technical solution: for each category of performance data, the actual performance weight data of the preset operating data type corresponding to the category performance data is calculated based on the category operation data and equipment operation data, and the result obtained is used as the actual performance weight data of the preset operating data type corresponding to the category performance data.

[0028] Calculate the ratio of the category performance data corresponding to the preset operating data type to the category target performance data to obtain the performance gap ratio for the preset operating data type. Use the performance gap ratio to conduct a preliminary performance analysis of the electromechanical equipment, and determine the equipment's performance status based on the size of the performance gap ratio.

[0029] By setting actual performance weight data, the contribution of different subcategories to the overall performance can be more accurately reflected, thereby improving the accuracy of performance evaluation.

[0030] The actual performance weight data is set based on the sum of the subcategory operating performance ratios, ensuring that the performance contribution of each subcategory is quantified.

[0031] By calculating the target performance data of each category, we can clearly identify the performance level that the equipment should have when it reaches its ideal state. The acquisition of target performance data also takes into account the weight of the performance of each category, thus achieving high performance targets for important categories. By calculating the performance gap ratio, the gap between the current performance of the device and the ideal performance can be quantified.

[0032] In one embodiment of the present invention, performing preliminary performance analysis on electromechanical equipment through performance gap comparison to obtain performance status determination information includes: Obtain the sum of the performance gap ratios of all preset operating data types to obtain the equipment performance gap ratio; Obtaining a preset performance gap threshold, comparing the device performance gap ratio with the preset performance gap threshold, and obtaining a device performance comparison result; The operating performance status of the electromechanical equipment is determined according to the equipment performance comparison result to obtain performance status determination information of the electromechanical equipment.

[0033] When the equipment performance gap ratio is greater than the preset performance gap threshold, the electromechanical equipment is preliminarily judged as qualified; When the equipment performance gap ratio is less than or equal to the preset performance gap threshold, the electromechanical equipment is preliminarily judged to be unqualified in performance.

[0034] The working principle and technical effect of the above technical solution: For each preset operating data type, the performance gap ratio is calculated. The performance gap ratios for all preset operating data types are summed to obtain the device performance gap ratio. The device performance gap ratio integrates the performance of the device under different operating data types to form a comprehensive performance gap indicator.

[0035] The preset performance gap threshold is a pre-set standard used to measure whether the performance of the device reaches an acceptable level.

[0036] Compare the calculated device performance gap ratio to the preset performance gap threshold. If the device performance gap ratio is greater than the preset performance gap threshold, it indicates that the device has good overall performance. If the device performance gap ratio is less than or equal to the preset performance gap threshold, it indicates that there is a significant gap in the overall performance of the device.

[0037] The operating performance status of the electromechanical equipment is determined based on the comparison of the equipment performance gap ratio with the preset performance gap threshold. If the equipment performance gap ratio is greater than the preset performance gap threshold, the equipment performance is preliminarily determined to be qualified; if the equipment performance gap ratio is less than or equal to the preset performance gap threshold, the equipment performance is preliminarily determined to be unqualified.

[0038] By calculating the device performance gap ratio, we can comprehensively assess the performance of the device under different operating data types, avoiding the one-sidedness of single-metric evaluation. If the device performance initially fails, we can conduct a deeper analysis to determine which operating data types have the largest performance gaps and conduct targeted analysis and judgment.

[0039] In one embodiment of the present invention, the step of performing single-machine operation efficiency analysis and coordinated operation efficiency analysis on electromechanical equipment to obtain single-machine coordinated operation efficiency determination information of the equipment includes: Obtaining category performance data, subcategory performance data, subcategory performance ratio, category performance ratio, and performance gap ratio of a single-machine operation of electromechanical equipment to obtain a single-machine operation data group of the electromechanical equipment; Obtaining category performance data, subcategory performance data, subcategory operation performance ratio, category operation performance ratio, and performance gap ratio of the coordinated operation of electromechanical equipment, and obtaining a coordinated operation performance group of the electromechanical equipment; Performing single-machine performance evaluation on electromechanical equipment based on the performance gap comparison of single-machine operation of electromechanical equipment to obtain single-machine performance evaluation information; Perform linkage efficiency assessment on electromechanical equipment based on the efficiency gap between the linkage operations of electromechanical equipment to obtain linkage efficiency assessment information; Perform performance analysis and judgment on the single-machine operation performance group and the linkage operation performance group to obtain the equipment single-machine linkage performance judgment information; The difference calculation and comparative analysis of the individual data of the electromechanical equipment's stand-alone and coordinated operation performance groups are performed to obtain performance anomaly location data for the stand-alone and coordinated operation performance groups. The data includes category performance data, subcategory performance data, subcategory performance ratios, category performance ratios, and performance gap ratios.

[0040] The working principle and technical effect of the above technical solution: Through sensors and other means, category performance data, subcategory performance data, subcategory performance ratios, category performance ratios, and performance gap ratios are obtained for electromechanical equipment in stand-alone operation mode. These various performance data are then obtained for electromechanical equipment in coordinated operation mode to form coordinated operation performance groups. Coordinated operation refers to the coordinated operation of multiple devices or systems.

[0041] Based on the performance gap ratio in the single-machine operation data set, the single-machine operation performance of the electromechanical equipment is determined. If the performance gap ratio exceeds a preset threshold, the single-machine performance is determined to be unqualified.

[0042] The interlocking operation efficiency of the electromechanical equipment is determined based on the efficiency gap ratio in the interlocking operation efficiency group.

[0043] A comprehensive performance analysis is conducted on both the standalone and coordinated operation performance groups, comparing differences in category and subcategory performance data, as well as the impact of these differences on overall performance. This analysis provides information on the performance of both standalone and coordinated equipment, specifically the performance relationship and optimization potential between standalone and coordinated operation.

[0044] Calculate the difference between individual machine performance groups and the coordinated performance groups, including category performance data, subcategory performance data, subcategory performance ratios, category performance ratios, and performance gap ratios. By comparing these differences, you can pinpoint the specific operating module with performance anomalies.

[0045] Performance anomaly location data improves the efficiency of performance anomaly identification, reduces troubleshooting time, and improves maintenance efficiency.

[0046] By using the single-machine linkage efficiency determination information, the efficiency relationship between single-machine operation and linkage operation can be analyzed, the efficiency can be evaluated separately, and then the difference between single-machine efficiency and linkage efficiency can be analyzed.

[0047] By improving equipment efficiency and accurately locating performance anomalies, equipment energy consumption, maintenance costs and downtime can be reduced.

[0048] In one embodiment of the present invention, the step of performing performance analysis and determination on the stand-alone operation performance group and the linkage operation performance group to obtain the stand-alone linkage performance determination information of the equipment includes: When the single-machine performance determination information and the linkage performance determination information are the same and both are qualified performance determinations, the electromechanical equipment is subjected to qualified performance determinations; When the single-machine performance determination information and the linkage performance determination information are different or both are unqualified performance determinations, the electromechanical equipment is subjected to an unqualified abnormal determination of the single-machine linkage performance, and the single-machine linkage performance determination information of the equipment is obtained; When the single-machine performance of the electromechanical equipment is judged as unqualified, the single-machine performance unqualified judgment of the electromechanical equipment is performed to obtain the unqualified judgment information of the equipment linkage performance; When the linkage efficiency of the electromechanical equipment is judged as unqualified, performing an unqualified linkage efficiency judgment on the electromechanical equipment to obtain unqualified linkage efficiency judgment information; When both the single-machine performance determination and the linkage performance determination of the electromechanical equipment are unqualified performance determinations, comprehensive unqualified equipment determination information is performed on the electromechanical equipment.

[0049] The working principle and technical effect of the above technical solution: When the single-machine performance determination information and the linkage performance determination information are both shown to be qualified, the overall qualified performance of the electromechanical equipment is determined.

[0050] If the single-machine performance determination information is different from the linkage performance determination information, or both are unqualified, the system will make an abnormal determination of unqualified single-machine linkage performance of the electromechanical equipment.

[0051] When the single-machine performance is judged to be unqualified, regardless of the result of the linkage performance judgment, the electromechanical equipment will be judged to be unqualified for the single-machine performance, and the corresponding equipment linkage performance unqualified judgment information will be generated.

[0052] When the linkage efficiency is judged to be unqualified, the electromechanical equipment is also judged to be unqualified for the equipment linkage efficiency, and equipment linkage efficiency unqualified judgment information is generated.

[0053] If both the single-machine performance judgment and the linkage performance judgment are unqualified, the system will conduct a comprehensive equipment unqualified judgment on the electromechanical equipment and generate comprehensive equipment unqualified judgment information.

[0054] By comprehensively considering the results of single-machine and linkage performance judgments, the overall performance status of electromechanical equipment can be evaluated more accurately, avoiding misjudgments that may be caused by a single judgment mode.

[0055] The generation of unqualified performance judgment information can timely discover problems existing in electromechanical equipment in stand-alone or linkage mode, thereby improving the efficiency and life of the equipment.

[0056] In one embodiment of the present invention, performing differential calculation and comparative analysis on the individual data of the single-machine operation performance group and the coordinated operation performance group of the electromechanical equipment to obtain performance anomaly location data of the single-machine operation performance group and the coordinated operation performance group includes: Calculate the difference between the individual data of the single-machine operation efficiency group and the linkage operation efficiency group of the electromechanical equipment to obtain the single-machine linkage difference data of multiple data types; Compare the single-machine linkage difference data with the preset difference threshold to obtain the difference comparison result; Based on the difference comparison results and the equipment single-machine linkage performance judgment information, performance anomaly judgment is performed on each data of the single-machine operation performance group and the linkage operation performance group to obtain performance anomaly positioning data of the single-machine operation performance group and the linkage operation performance group.

[0057] The working principle and technical effects of the above technical solution are as follows: Data on the performance of individual electromechanical equipment and their coordinated operation is obtained. The difference between each corresponding item in the two data sets is calculated to form individual and coordinated operation difference data. The difference data is compared with a preset threshold. A determination is made as to whether the difference is normal. The difference comparison result is combined with the individual and coordinated operation performance determination information. Abnormal data items in the individual and coordinated operation performance groups are identified. Data items with performance anomalies are quickly identified, reducing troubleshooting time and improving maintenance efficiency. Performance data is analyzed to optimize equipment operation.

[0058] In one embodiment of the present invention, the system includes: An evaluation and classification module is used to collect equipment operation data and equipment performance data of each electromechanical equipment to be evaluated for operation performance, and to perform preliminary classification and reclassification to obtain sub-category operation data of the category operation data and sub-category performance data of the category performance data; The proportion analysis module is used to perform performance proportion analysis on sub-category performance data to obtain sub-category operation energy efficiency ratios, perform performance proportion analysis on category performance data to obtain category operation efficiency ratios, set actual performance weight data based on equipment operation data and category operation data, and then obtain category target performance data, and then obtain performance gap ratios for preset operation data categories; The preliminary performance evaluation module is used to obtain the equipment performance gap ratio, perform performance comparison analysis and judgment based on the equipment performance gap ratio, and obtain performance status judgment information of the electromechanical equipment; The single-machine linkage efficiency analysis module is used to perform single-machine operation efficiency analysis and linkage operation efficiency analysis on electromechanical equipment, and then obtain the equipment single-machine linkage efficiency judgment information.

[0059] The working principle and technical effect of the above technical solution are as follows: the equipment operation data and equipment efficiency data of each electromechanical equipment for operation efficiency evaluation are collected, and preliminary classification and reclassification are performed to obtain sub-category operation data of the category operation data and sub-category efficiency data of the category efficiency data; by refining and refining the equipment, in-depth data efficiency analysis of the electromechanical equipment can be achieved, improving the accuracy and comprehensiveness of the efficiency analysis. This realizes a comprehensive and targeted analysis of the efficiency of the electromechanical equipment; Perform efficiency ratio analysis on subcategory efficiency data to obtain subcategory operating energy efficiency ratio, and perform efficiency ratio analysis on category efficiency data to obtain category operating efficiency ratio. Through efficiency ratio analysis, the efficiency contribution of each category and subcategory in the overall electromechanical equipment can be obtained, and the efficiency analysis of the weights of categories and subcategories can be further obtained, which simplifies the complexity of efficiency calculation, realizes the differentiation of efficiency analysis complexity, and improves task completion.

[0060] Actual performance weight data is set based on equipment operation data and category operation data, thereby obtaining category target performance data and then obtaining the performance gap ratio of the preset operation data category. The actual performance weight data set based on the category performance ratio is more closely aligned with the performance characteristics of the category, allowing higher performance categories to be assigned more weights, thereby optimizing the performance of electromechanical equipment and enhancing its performance. Obtain the equipment efficiency gap ratio, conduct efficiency comparison analysis and judgment based on the equipment efficiency gap ratio, and obtain efficiency status judgment information of the electromechanical equipment; by obtaining the equipment efficiency gap ratio to accurately quantify the efficiency of the equipment, the operating efficiency of the electromechanical equipment can be efficiently obtained; Perform stand-alone and linkage performance analysis on electromechanical equipment to obtain information on the equipment's stand-alone and linkage performance. This allows for targeted analysis of different electromechanical equipment operating scenarios, enabling accurate assessment of both stand-alone and linkage performance.
