[0002] Carbon emission activity level monitoring equipment is widely used in industrial production, transportation, energy and other fields to monitor and record carbon emission data in real time. Carbon emission activity level monitoring equipment can accurately capture the activity level of carbon emission sources through the application of sensors, data acquisition systems and network transmission technology, and can upload carbon emission data to the carbon emission central management system, which can provide a scientific basis for the quantitative analysis of carbon emissions and the formulation of emission reduction strategies.

[0003] Although carbon emission activity level monitoring equipment plays an important role in carbon emission monitoring, its operation and maintenance process faces many challenges. The working environment of carbon emission activity level monitoring equipment is usually harsh, especially in an environment with high temperature, high humidity or corrosive gas. Sensors and data acquisition systems are easily damaged, resulting in data distortion or equipment failure. Due to the wide distribution of carbon emission monitoring equipment, operation and maintenance personnel need to conduct regular inspections and maintenance to ensure the normal operation of the equipment.

[0032] The traditional manual inspection method of carbon emission activity level monitoring equipment is inefficient and difficult to cover all equipment, which is prone to missed inspections or delayed maintenance. As the carbon emission activity level monitoring equipment ages, hardware aging and untimely software updates, it is easy to cause the performance of the carbon emission activity level monitoring equipment to decline, resulting in a decrease in the accuracy of the monitoring data.

[0033] Based on the above reasons, an embodiment of the present application provides a carbon emission monitoring equipment operation and maintenance method based on the Internet of Things, and the method includes: obtaining multiple time series collection results of the collection equipment in the target area based on the Internet of Things, clustering the multiple time series collection results according to the production scheduling characteristics, and obtaining multiple time series collection result clusters and production scheduling characteristics corresponding to each time series collection result cluster, each time series collection result cluster includes multiple time series collection results with similar production scheduling characteristics; wherein the collection equipment is used to collect carbon emission activity level data; determine the time series change characteristics of each time series collection result, and determine the distinguishing state characteristics of each time series collection result relative to the production scheduling characteristics of the time series collection result cluster to which it belongs; through the anomaly detection model, determine the abnormal time series collection result according to the time series change characteristics and the distinguishing state characteristics, and prompt the collection equipment corresponding to the abnormal time series collection result to be repaired. The method in the embodiment of the present application can cluster multiple time series collection results according to production scheduling characteristics, and can determine abnormal time series collection results based on the time series change characteristics of the time series collection results and the distinctive state characteristics of the time series collection results relative to the production scheduling characteristics of the time series collection result cluster to which they belong, thereby achieving accurate detection of abnormal time series collection results, improving the monitoring efficiency of carbon emission monitoring equipment, and enabling efficient monitoring of carbon emission monitoring equipment.

[0034] In some scenarios, a carbon emission monitoring equipment operation and maintenance method based on the Internet of Things in an embodiment of the present application can be applied to efficient monitoring equipment of carbon emission monitoring equipment in factories, enterprises, institutions, etc., thereby improving the monitoring accuracy and efficiency of carbon emission monitoring equipment.

[0035] The following is a detailed description of an operation and maintenance method for carbon emission monitoring equipment based on the Internet of Things provided in an embodiment of the present application with reference to specific examples.

[0036] Figure 1 A flowchart of a carbon emission monitoring equipment operation and maintenance method based on the Internet of Things provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes S110 to S120, and S110 to S120 are described in detail below.

[0037] S110, based on the Internet of Things, multiple time series collection results of the collection equipment in the target area are obtained, and the multiple time series collection results are clustered according to the production scheduling characteristics to obtain multiple time series collection result clusters and the production scheduling characteristics corresponding to each time series collection result cluster, each time series collection result cluster includes multiple time series collection results with similar production scheduling characteristics. Wherein, the collection equipment is used to collect carbon emission activity level data.

[0038] like Figure 1 As shown, in an embodiment of the method, multiple time-series collection results of collection devices in the target area can be first obtained based on the Internet of Things. The collection devices are used to collect carbon emission activity level data in time series, and then the accuracy of the carbon emission detection equipment can be monitored according to the carbon emission activity level data.

[0039] Exemplarily, the collection device may be a gas sensor (e.g., CO sensor, methane sensor) to monitor the concentration of the emission gas, which can characterize the activity level; the collection device may also be a flow meter, which is used to measure the flow of gas or liquid and calculate the emission, which can characterize the activity level; the collection device may also be an energy consumption monitoring device, which is used to record the consumption of energy such as electricity and fuel, which can characterize the activity level; the collection device may also be a GPS and Internet of Things device, which is used to track the emission activities of mobile sources (e.g., vehicles), which can characterize the activity level. Through the above-mentioned collection devices, the activity level data can be collected through the collection device, and then the status of the monitoring device can be monitored according to the activity level data.

[0040] For example, after acquiring the carbon emission activity level data, the collection device can upload the data to the management system through the data collection system and network transmission technology. The management system can process and analyze the data to obtain the time series collection results.

[0041] After obtaining multiple time series acquisition results, the multiple time series acquisition results can be clustered according to the production scheduling characteristics, thereby obtaining multiple time series acquisition result clusters, each of which includes multiple time series acquisition results with similar production scheduling characteristics, and each time series acquisition result cluster also has corresponding production scheduling characteristics.

[0042] Exemplarily, production scheduling features may include features such as the working mode and production time of the working equipment that needs to collect activity level data. Through clustering, time series collection results with similar production scheduling features can be grouped into one category to form multiple time series collection result clusters.

[0043] S120, determining the time series variation characteristics of each time series collection result, and determining the distinguishing state characteristics of each time series collection result relative to the production scheduling characteristics of the time series collection result cluster to which it belongs. Through the abnormality detection model, the abnormal time series collection result is determined according to the time series variation characteristics and the distinguishing state characteristics, and a prompt is given to repair the collection equipment corresponding to the abnormal time series collection result.

[0044] During detection, the time series variation characteristics of each time series acquisition result can be determined. The time series variation characteristics represent the variation characteristics of the time series acquisition result over time. Then, whether the time series acquisition result is abnormal in time sequence can be judged according to the time series variation characteristics.

[0045] Exemplarily, the time series variation feature may include a fluctuation amplitude feature of the data.

[0046] During detection, the timing change characteristics of each timing collection result can be determined, and the distinguishing state characteristics of each timing collection result relative to the production scheduling characteristics of the timing collection result cluster to which it belongs can be determined. The distinguishing state characteristics reflect the difference between a certain timing collection result and other timing collection results in the timing collection result cluster where the timing collection result is located, and abnormal timing collection results can be identified based on the distinguishing state characteristics.

[0047] Figure 2 A schematic diagram of a work flow of a carbon emission monitoring equipment operation and maintenance method based on the Internet of Things provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, after obtaining the timing change characteristics and distinguishing state characteristics, the abnormal timing collection results can be determined according to the timing change characteristics and distinguishing state characteristics through the abnormal detection model, and the collection equipment corresponding to the abnormal timing collection results can be prompted to be repaired to realize the detection of the working status of the collection equipment.

[0048] Illustratively, when the method in the embodiment of the present application is working and detecting in a certain industrial production scenario, if the timing collection results of a certain collection device show that the carbon emission level of the timing collection results suddenly increases significantly in time series, and this change is significantly different from the collection results of other collection devices in the timing collection result cluster where the timing collection results are located, then the collection device may have a fault or abnormality, and the system will prompt the operation and maintenance personnel to inspect the device.

[0049] Exemplarily, the anomaly detection model can be based on a machine learning algorithm and can be implemented by learning the characteristics of normal and abnormal states through training data, so that abnormal time series acquisition results can be identified in practical applications.

[0050] The beneficial effect of the above-mentioned implementation method is that, compared with the traditional manual inspection method, the method of the present application realizes real-time monitoring and intelligent operation and maintenance of carbon emission monitoring equipment through Internet of Things technology. By clustering and anomaly detection of time series collection results, it can timely discover abnormal conditions of collection equipment and prompt operation and maintenance personnel to carry out maintenance, thereby improving operation and maintenance efficiency and the reliability of collection equipment.

[0051] The beneficial effect of the above-mentioned implementation method is that, when performing anomaly detection on the time series collection results, it is possible to judge whether the time series collection results are abnormal time series collection results based on the changing characteristics of the carbon emission levels in the time series of the time series collection results and the distinguishing characteristics of the time series collection results of other collection devices in the time series collection result cluster where the time series collection results are located, thereby improving the accuracy of the judgment on whether the time series collection results are abnormal.

[0052] In some implementations, in the above-mentioned S120, the distinguishing status characteristics of each timing collection result relative to the production scheduling characteristics of the timing collection result cluster to which it belongs are determined, including: determining the scheduling mutation point and scheduling cycle of the production scheduling characteristics of the timing collection result cluster to which each timing collection result belongs, and determining the collection result mutation point and collection result cycle of each timing collection result, determining the mutation distinguishing characteristics according to the scheduling mutation point and the collection result mutation point, and determining the collection cycle distinguishing characteristics according to the scheduling cycle and the collection result cycle, and determining the distinguishing status characteristics according to the mutation distinguishing characteristics and the collection cycle distinguishing characteristics of each timing collection result.

[0053] In order to determine the distinguishing state features, the distinguishing state features can be determined from the mutation features of the activity level changes and the periodic features of the activity level changes in the time series acquisition results, thereby improving the accuracy of the distinguishing state features.

[0054] When determining the distinguishing state characteristics, the scheduling mutation point and scheduling cycle of the production scheduling characteristics of the timing collection result cluster to which each timing collection result belongs can be determined first. The scheduling mutation point is the mutation time of the timing collection result cluster to which the timing collection result belongs, and the scheduling cycle is the production scheduling cycle of the timing collection result cluster.

[0055] When determining the distinguishing state features, the acquisition result mutation point and the acquisition result cycle of each time series acquisition result may be determined first. The acquisition result mutation point represents the mutation time of the time series acquisition result, and the acquisition result cycle is the cycle in which the time series acquisition result changes.

[0056] When determining the distinguishing state features subsequently, the mutation distinguishing features can be determined according to the scheduling mutation points and the collection result mutation points. The mutation distinguishing features represent the difference between the mutation time of the time series collection result cluster where the time series collection result is located and the mutation time of the time series collection result.

[0057] When determining the distinguishing state characteristics subsequently, the collection cycle distinguishing characteristics can be determined according to the scheduling cycle and the collection result cycle, where the scheduling cycle is the difference between the production scheduling cycle of the time series collection result cluster and the cycle in which the time series collection results change.

[0058] Exemplarily, the mutation points and periodic characteristics of the production schedule can be identified by using time series analysis methods, such as sliding window analysis, Fourier transform, etc.; similar methods can be used to analyze the mutation points and periodic characteristics of the collection results; by comparing these characteristics, the differences between the production schedule and the collection results can be identified, and these differences are used to determine distinguishing state characteristics.

[0059] After obtaining the mutation distinguishing features and the acquisition cycle distinguishing features, the distinguishing state features can be determined according to the mutation distinguishing features and the acquisition cycle distinguishing features of each time series acquisition result. The distinguishing state features characterize the mutation features and the cycle features of the time series acquisition results, thereby improving the detection accuracy of abnormal time series acquisition results.

[0060] The beneficial effect of the above-mentioned implementation method is that the distinguishing state characteristics are determined according to the mutation distinguishing characteristics and the collection cycle distinguishing characteristics of each time series collection result, which can improve the detection accuracy of abnormal time series collection results, better adapt to complex production environments, reduce missed detections and false detections, and improve equipment maintenance efficiency and data accuracy.

[0061] Figure 3 A flow chart of a second method for operating and maintaining carbon emission monitoring equipment based on the Internet of Things provided in an embodiment of the present application is shown in FIG. Figure 3As shown, in the above S120, the distinguishing state characteristics can be determined according to the mutation distinguishing characteristics and the acquisition cycle distinguishing characteristics of each time series acquisition result, including S121 to S122, and S121 to S122 are specifically described below.

[0062] S121, determine the global mutation amplitude mean of the scheduling mutation points of all the time series collection results in all the time series collection result clusters, the difference mutation amplitude mean corresponding to the scheduling mutation points of all the time series collection results of each time series collection result cluster, and determine the ratio of the difference mutation amplitude mean to the global mutation amplitude mean as the mutation feature weight of each time series collection result cluster. Determine the global scheduling cycle mean of the scheduling cycle of all the time series collection results of all the time series collection result clusters, the collection result cycle mean of all the time series collection results of each time series collection result cluster, and determine the ratio of the global scheduling cycle mean to the collection result cycle mean as the collection cycle feature weight of each time series collection result cluster.

[0063] In order to further improve the accuracy of determining the distinguishing state characteristics, the global mutation amplitude mean of the scheduling mutation points of all time series collection results in all time series collection result clusters and the distinguishing mutation amplitude mean corresponding to the scheduling mutation points of all time series collection results in each time series collection result cluster can be determined. The global mutation amplitude mean represents the mutation amplitude of the activity level in the scheduling of all time series collection results in all time series collection result clusters, and the distinguishing mutation amplitude mean represents the mutation amplitude of the activity level of all time series collection results in each time series collection result cluster.

[0064] After obtaining the mean value of the distinguishing mutation amplitude and the mean value of the global mutation amplitude, the ratio of the mean value of the distinguishing mutation amplitude to the mean value of the global mutation amplitude can be determined as the mutation feature weight of each time series acquisition result cluster. The mutation feature weight represents the ratio of the mutation amplitude of each time series acquisition result cluster to the mutation amplitude of all time series acquisition result clusters. Then, the weight corresponding to the activity level mutation amplitude of the time series acquisition results within the time series acquisition result cluster can be determined according to the mutation feature weight.

[0065] In order to further improve the accuracy of determining the distinguishing state characteristics, the global scheduling cycle mean of the scheduling cycles of all timing collection results of all timing collection result clusters and the collection result cycle mean of all timing collection results of each timing collection result cluster can be determined. The global scheduling cycle mean represents the cycle mean of the activity level changes of the timing collection results of all timing collection result clusters, and the collection result cycle mean represents the cycle mean of the activity level changes of all timing collection results in each timing collection result cluster.

[0066] After obtaining the global scheduling cycle mean and the collection result cycle mean, the ratio of the global scheduling cycle mean to the collection result cycle mean can be determined as the collection cycle feature weight of each time series collection result cluster, and then the weight of each time series collection result cluster relative to the global activity level change cycle can be determined based on the collection cycle feature weight.

[0067] S122. Determine the sum of the product of the mutation distinguishing feature and the mutation feature weight, and the product of the collection cycle distinguishing feature and the collection cycle feature weight as the distinguishing state feature.

[0068] After obtaining the mutation feature weight and the acquisition cycle feature weight, the sum of the product of the mutation distinguishing feature and the mutation feature weight, and the product of the acquisition cycle distinguishing feature and the acquisition cycle feature weight can be determined as the distinguishing state feature. The distinguishing state feature combines the weight corresponding to the activity level mutation amplitude of the time series acquisition results within each time series acquisition result cluster and the weight of the cycle of activity level change of each time series acquisition result cluster relative to the global one to determine the distinguishing state feature, thereby improving the scientificity and reliability of the distinguishing state feature.

[0069] The beneficial effect of the above-mentioned implementation method is that the weight corresponding to the activity level mutation amplitude of the time series acquisition results within each time series acquisition result cluster and the weight of the period of activity level change of each time series acquisition result cluster relative to the global one are combined to determine the distinguishing state characteristics, which improves the scientificity and reliability of determining the distinguishing state characteristics, can more accurately reflect the changing characteristics and periodic characteristics of the time series acquisition results, and improves the accuracy and reliability of anomaly detection.

[0070] Figure 4 A flow chart of a third method for operating and maintaining a carbon emission monitoring device based on the Internet of Things provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the above method further includes S210 to S220, and S210 to S220 are described in detail below.

[0071] S210. Based on the Internet of Things, the production schedule adjustment information corresponding to the collection devices in the target area is obtained, the adjustment ratio of the production schedule adjustment in the collection devices corresponding to each time series collection result cluster is determined, and the variance value of the production schedule adjustment in the collection devices corresponding to each time series collection result cluster is determined.

[0072] When detecting abnormal time series acquisition results through time series acquisition result clusters, the production schedule adjustment information corresponding to the acquisition devices in the target area can be obtained based on the Internet of Things, and the production schedule adjustment information represents the production schedule adjustment of the activity level collected by the acquisition devices; at the same time, the adjustment ratio of the production schedule adjustment in the acquisition devices corresponding to each time series acquisition result cluster can be determined, and the adjustment ratio of the production schedule adjustment represents the quantitative ratio of the production schedule adjustment, and the variance value of the production schedule adjustment of the acquisition devices corresponding to each time series acquisition result cluster can be determined, and the variance value of the production schedule adjustment represents the dispersion range of the production schedule adjustment of the acquisition devices corresponding to the time series acquisition result cluster, and then it can be determined whether the time series acquisition result clusters need to be re-clustered according to the quantitative ratio of the production schedule adjustment and the dispersion range of the production schedule adjustment.

[0073] S220: When the first adjustment ratio corresponding to the first time series acquisition result cluster is greater than the preset adjustment ratio, and the first variance value corresponding to the first time series acquisition result cluster is greater than the preset variance value, re-clustering the multiple time series acquisition results according to the production scheduling characteristics.

[0074] After obtaining the adjustment ratio corresponding to the timing acquisition result cluster and the variance value corresponding to the timing acquisition result cluster, when the first adjustment ratio corresponding to the first timing acquisition result cluster is greater than the preset adjustment ratio, and the first variance value corresponding to the first timing acquisition result cluster is greater than the preset variance value, it means that the adjustment ratio of the number of acquisition devices in the timing acquisition result cluster is high, and the dispersion of the adjustment of the production schedule of the acquisition devices in the timing acquisition result cluster is too large, and then the multiple timing acquisition results can be re-clustered according to the production scheduling characteristics to ensure the accuracy of the subsequent determination of the abnormal timing acquisition results in the acquisition result cluster.

[0075] Exemplarily, in the above method, when determining whether it is necessary to re-cluster the time series acquisition results, it can be achieved through the following steps: 1. The adjustment of the production schedule can be monitored in real time through sensors installed on the production equipment, and the data can be transmitted to the control system for analysis. 2. By performing statistical analysis on the collected production scheduling data, the variance value corresponding to each cluster of time series acquisition results is calculated to evaluate the stability of the production schedule. 3. When it is detected that the adjustment ratio and variance value exceed the preset threshold, the control system automatically triggers the re-clustering process and re-cluster the time series acquisition results according to the latest production scheduling characteristics.

[0076] The beneficial effect of the above implementation method is that when it is detected that the adjustment ratio and variance value of a certain time series acquisition result cluster exceeds the preset threshold, the system will re-cluster the time series acquisition results according to the latest production scheduling characteristics. This dynamic adjustment mechanism can timely reflect changes in production scheduling and improve the accuracy and effectiveness of the time series acquisition results.

[0077] Figure 5 A flowchart of a fourth method for operating and maintaining a carbon emission monitoring device based on the Internet of Things provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the above method also includes S310 to S320, and S310 to S320 are described in detail below.

[0078] S310. Obtain historical maintenance records of each collection device in the target area based on the Internet of Things, determine historical maintenance cycles of each collection device in the target area according to the historical maintenance records, and determine an average maintenance cycle of each collection device in the target area.

[0079] When determining whether it is necessary to re-cluster all collection devices to obtain a time series collection result cluster, the historical maintenance record of each collection device in the target area can be obtained based on the Internet of Things, and the historical maintenance cycle of each collection device in the target area can be determined based on the historical maintenance record. The historical maintenance cycle represents the time period for maintenance and repair of each collection device in the target area.

[0080] After obtaining the maintenance and overhaul time period of each acquisition device in the target area, the average maintenance period of each acquisition device in the target area may be determined, where the average maintenance period represents the mean of the maintenance period of each acquisition device in the target area.

[0081] For example, the maintenance information of each device can be collected and recorded in real time through the Internet of Things technology and stored in a cloud database. By performing statistical analysis on these data, the historical maintenance cycle and average maintenance cycle of each device can be calculated.

[0082] S320: Determine the ratio of the historical maintenance cycle to the average maintenance cycle of each collection device as the maintenance factor of each collection device, and adjust the distinguishing state feature by multiplying the maintenance factor by the distinguishing state feature.

[0083] After obtaining the average maintenance cycle, the ratio of the historical maintenance cycle of each collection device to the average maintenance cycle can be determined as the maintenance factor of each collection device. The maintenance factor represents the maintenance frequency of each collection device in the historical time period.

[0084] After obtaining the maintenance factor, the distinguishing state characteristic can be adjusted by multiplying the maintenance factor on the distinguishing state characteristic, and then the distinguishing state characteristic can be adjusted by the maintenance factor, so that the distinguishing state characteristic increases when the maintenance frequency of the acquisition device is higher, and decreases when the maintenance frequency of the acquisition device is lower.

[0085] Exemplarily, the calculation of the maintenance factor can be achieved by writing a corresponding algorithm and applying it to the adjustment process of distinguishing status characteristics, which can more accurately evaluate the health status of the equipment, timely detect and handle abnormal situations, and improve the operation and maintenance efficiency and reliability of the equipment.

[0086] The beneficial effect of the above-mentioned implementation method is that by determining the ratio of the historical maintenance cycle and the average maintenance cycle of each collection device as a maintenance factor, and adjusting the distinguishing status characteristics through the maintenance factor, the distinguishing status characteristics are increased when the maintenance frequency of the collection device is higher, and the distinguishing status characteristics are reduced when the maintenance frequency of the collection device is lower.

[0087] In some implementations, the above method also includes: when the first adjustment ratio corresponding to the first time series acquisition result cluster is greater than the preset adjustment ratio, and the first variance value corresponding to the first time series acquisition result cluster is greater than the preset variance value, the multiple time series acquisition results are re-clustered according to the production scheduling characteristics and maintenance factors.

[0088] When determining whether multiple time series acquisition results need to be re-clustered, when the first adjustment ratio corresponding to the first time series acquisition result cluster is greater than the preset adjustment ratio, and the first variance value corresponding to the first time series acquisition result cluster is greater than the preset variance value, the multiple time series acquisition results can be re-clustered according to the production scheduling characteristics and maintenance factors, and the acquisition equipment with similar maintenance history can be maintained in combination with the maintenance factors.

[0089] Exemplarily, the re-clustering process can be implemented in a variety of ways. A clustering method based on the K-means algorithm can be used to classify the time series acquisition results according to new features; or a method based on hierarchical clustering can be used to reclassify by calculating the similarity between the acquisition results.

[0090] The beneficial effect of the above-mentioned implementation method is that by introducing maintenance factors and re-clustering methods, the problem of abnormal timing collection results caused by production schedule adjustment and equipment maintenance is effectively solved. This technical solution can more accurately reflect the actual production and maintenance status, and can improve the operation and maintenance efficiency and data accuracy of carbon emission monitoring equipment.

[0091] In some implementations, the above method further includes S410 to S420, and S410 to S420 are described in detail below.

[0092] S410: Obtain the maintenance times of the collection devices in the first time series collection result cluster in the historical time period, and determine the ratio of the maintenance times to the standard maintenance times as a maintenance times adjustment factor.

[0093] When it is determined that multiple time series acquisition results need to be re-clustered, the maintenance times of the acquisition devices in the first time series acquisition result cluster within the historical time period can be obtained, and the ratio of the maintenance times to the standard maintenance times can be determined as a maintenance times adjustment factor. The maintenance times adjustment factor represents the ratio of the maintenance times of all acquisition devices in the time series acquisition result cluster to the standard maintenance times.

[0094] For example, the data acquisition module in the IoT system can be used to regularly record the maintenance times of each acquisition device and store them in the management system. The data processing module can be used to analyze the historical maintenance data and calculate the maintenance times adjustment factor for each time series acquisition result cluster.

[0095] S420: Multiply the preset adjustment ratio corresponding to the first time series acquisition result cluster by the maintenance times adjustment factor to adjust the preset adjustment ratio corresponding to the first time series acquisition result cluster. Multiply the preset variance value corresponding to the first time series acquisition result cluster by the maintenance times adjustment factor to adjust the preset variance value corresponding to the first time series acquisition result cluster.

[0096] After obtaining the maintenance times adjustment factors of all timing acquisition result clusters, the preset adjustment ratio corresponding to the first timing acquisition result cluster can be multiplied by the maintenance times adjustment factor to adjust the preset adjustment ratio corresponding to the first timing acquisition result cluster, and then the maintenance times adjustment factor can be combined to determine whether the timing acquisition result clusters need to be re-clustered.

[0097] After obtaining the maintenance times adjustment factors of all timing acquisition result clusters, the preset variance value corresponding to the first timing acquisition result cluster can be multiplied by the maintenance times adjustment factor to adjust the preset variance value corresponding to the first timing acquisition result cluster, and then the maintenance times adjustment factor can be combined to determine whether the timing acquisition result cluster needs to be re-clustered.

[0098] Exemplarily, the calculated adjustment factor may be automatically applied to a preset adjustment ratio and a preset variance value, thereby dynamically adjusting these parameters to accommodate different maintenance frequencies.

[0099] The beneficial effect of the above implementation is that, by introducing the maintenance frequency adjustment factor, the actual maintenance status of the time series acquisition result cluster can be more accurately reflected, thereby improving the accuracy of judging whether the time series acquisition result cluster needs to be re-clustered.

[0100] In some implementations, the method further includes: determining a historical time period in which the acquisition equipment in the first time series acquisition result cluster was not overhauled, and determining an average of the maintenance times of all time series acquisition result clusters in the historical time period as the standard maintenance times.

[0101] When determining the standard maintenance number, a historical time period in which the collection equipment in the first time series collection result cluster has not been overhauled can be determined, and the average of the maintenance times of all time series collection result clusters within the historical time period can be determined as the standard maintenance number, so that the maintenance times of the collection equipment within the historical time period exclude the interference of the maintenance times of the collection equipment in the first time series collection result cluster, and the maintenance frequency of the collection equipment in the first time series collection result cluster can be more accurately evaluated, thereby improving the accuracy of the relative frequency of maintenance of the collection equipment in the first time series collection result cluster.

[0102] The beneficial effect of the above-mentioned implementation method is that it eliminates the interference of the maintenance times of the acquisition equipment in the first time series acquisition result cluster, can improve the accuracy of the relative frequency of maintenance of the acquisition equipment in the first time series acquisition result cluster, and improves the accuracy and reliability of determining whether it is necessary to re-cluster the first time series acquisition result cluster.
