[0002] Switchgear plays a key role in distributing and controlling current in the power grid. They usually consume a certain amount of electrical energy to maintain operations, such as cooling systems and monitoring equipment. By optimizing the energy consumption of these systems, energy waste in the entire power grid system can be directly reduced. The energy efficiency framework based on behavioral change involves analyzing energy consumption footprints and related environmental background information to provide end users with tailored recommendations to optimize their energy use to achieve greater economic and ecological benefits.

[0003] The current research focuses on the use of energy-saving smart energy Internet technologies, which play an important role in designing a powerful energy-efficient ecosystem for remote collection and control, i.e. collecting data on indoor and outdoor environmental conditions, equipment energy consumption, end-user habits / activities and preferences. By tailoring different energy-saving measures to the end-user's behavior, about 20% of energy can be saved.

[0004] There are already some energy consumption prediction and optimization frameworks in the field of switchgear. (“Smart Home Energy Prediction and Optimization Based on Weather Metric Weight Coefficients”, Sensors 23, No. 7 (2023): 3640) proposed an optimization technique to solve the trade-off between energy conservation and user convenience in switchgear. In the study, not only temperature and humidity were considered, but also weather indicators such as air pressure, dew point and wind speed were introduced to more effectively optimize the indoor environment settings of the switchgear, thereby reducing energy costs. Although many advances have been made in the development of energy efficiency optimization frameworks in the field of switchgear, the main challenges that hinder the establishment of an effective framework for power equipment are mainly related to the following aspects: There is heterogeneity in data from different types of sensors.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0061] Example 1

[0062] Reference Figure 1 to Figure 3, which is the first embodiment of the present invention, and provides a multi-source sensor data fusion system for switch cabinet energy optimization, including:

[0063] Data ingestion layer, which is used to obtain real-time information data from different types of sensors.

[0064] The data fusion layer is used to preprocess and fuse the information data from the data ingestion layer to generate fused data with advanced features.

[0065] The data fusion layer includes low-level data fusion and mid-level data fusion;

[0066] The low-level data fusion is used to fuse the information data of the sensors to measure the same variable;

[0067] The intermediate data fusion is used to fuse information data from different sensors and extract high-level information from low-level fusion features;

[0068] First, the data of sensors of the same type are initially fused through low-level fusion to reduce data redundancy and increase data accuracy. Then, the data of sensors of different types are combined through intermediate fusion to extract higher-level information.

[0069] The sensor reads multiple temperatures (T 1 ,T 2 ,…,T n )、Light(L 1 ,L 2 ,…,L n ),humidity Sensors are processed through the data fusion layer to obtain fused data, such as fused temperature, fused light, fused humidity and fused CO 2 .

[0070] The operation steps of the low-level data fusion include:

[0071] Determine whether the number of sensors of the same type is greater than the value N. If it is greater than the value N, clean the acquired information data;

[0072] Remove the maximum and minimum values ​​of the information data, and calculate the average value of the remaining information data;

[0073] and calculating the difference between the maximum value and the average value of the information data and the difference between the minimum value and the average value of the information data, and comparing the sizes of the two differences;

[0074] When the difference between the maximum value and the average value is greater than the difference between the minimum value and the average value, the maximum value of the information data is removed and the average value of the remaining information data is calculated;

[0075] When the difference between the maximum value and the average value is less than the difference between the minimum value and the average value, the minimum value of the information data is removed and the average value of the remaining information data is calculated;

[0076] When the difference between the maximum value and the average value is equal to the difference between the minimum value and the average value, the average value of the information data is directly calculated;

[0077] Wherein, the value N≥4;

[0078] The data cleaning includes removing noise, filling missing values ​​and standardizing data formats;

[0079] For example, check whether the number of sensors of the same type is greater than N. In this example, the number of sensors is 5, which is greater than N (N=4), so data cleaning is required to obtain the maximum and minimum values ​​of all information data, where the maximum value is 23.5 and the minimum value is 20.5. After removing the maximum and minimum values, calculate the average value of the remaining information data. The data after removal is: [21.5, 22, 22.5]. The calculated average value = (21.5 + 22.0 + 22.5) / 3 = 22. Calculate the difference between the maximum value and the average value of the information data, and the difference between the minimum value and the average value of the information data, that is, the difference between the maximum value and the average value: 23.5-22.0 = 1.5, the difference between the minimum value and the average value: 22.0-20.5 = 1.5. In this example, the difference between the maximum value and the average value is equal to the difference between the minimum value and the average value (1.5 = 1.5). Therefore, the average value of the information data is directly calculated.

[0080] If the difference between the maximum value and the average value is greater than the difference between the minimum value and the average value, the maximum value: 23.5 is deleted, and then the average values ​​of the remaining four sets of data are calculated and the calculated average value is output.

[0081] The operation steps of the intermediate data fusion include:

[0082] Obtaining information data after low-level data fusion, and determining the type of the information data;

[0083] According to the matching information of the preset type, the matching information associated with the type of the information data is obtained, and the type of the matched information data is obtained;

[0084] Determine whether the matched information data type and the acquired information data type are from the same batch. If the two sets of information data are from the same batch, merge the two sets of information data. If they are not from the same batch, it indicates that the information data is missing.

[0085] Among them, the judgment conditions for whether the two sets of information data are from the same batch are:

[0086] Obtain the calculation time of two sets of information data, and determine whether the time interval is greater than the set value. When the time interval is greater than the set value, it means that the two sets of information data are not from the same batch. When the time interval is not greater than the set value, it means that the two sets of information data are from the same batch.

[0087] For example,

[0088] Temperature data after low-level data fusion: (timestamp, 22:10);

[0089] Humidity data after low-level data fusion: (timestamp, 15:20);

[0090] The temperature data and humidity data are stored as lists respectively. In this example, the temperature data and humidity data are preset matching types. The judgment condition is: the time interval is not greater than the set value (such as 10 minutes). When the timestamps match, the temperature and humidity data are merged into the same record. The timestamps of the temperature data and humidity data in this example do not meet the judgment conditions, which means that the two sets of information data are not from the same batch and will not be merged.

[0091] When the information data is merged, based on the historical working status of the switch cabinet, the historical information data closest to the two sets of information data is queried, and the timestamp of the historical information data is obtained, and the operating status or peripheral environment of the switch cabinet at that time is obtained according to the timestamp.

[0092] The decision engine layer is used to combine artificial intelligence algorithms with fused data to generate energy-saving suggestions and high-energy consumption alarms for switch cabinets.

[0093] The operation steps of the decision engine layer include:

[0094] Obtain fused data after fusing two sets of intermediate data, perform high-level fusion on the two sets of fused data, and generate high energy consumption alerts and energy-saving suggestions for each energy optimization use case;

[0095] When generating high energy consumption alerts and energy-saving suggestions for each energy optimization use case, based on the historical working status of the switch cabinet, when one set of fused data is within the set range and other fused data is not within the range, the weight of the fused data is adaptively adjusted;

[0096] The high energy consumption alert and energy saving suggestion are formulated as a time series classification task.

[0097] Data presentation layer, used to display energy consumption analysis and provide interactive dashboards.

[0098] When displaying energy consumption analysis, the data display layer will judge the received information. The specific judgment method is:

[0099] Generate a set table according to the content to be displayed, extract the corresponding information from the database, and fill the information into the set table in sequence;

[0100] Extract the same table from the repository, collect the information of the same table, compare the information of the two sets of tables, and determine whether the difference of the information is less than the error value;

[0101] When it is less than the error value, the corresponding switch cabinet energy usage status information in the integrated storage library is used to give the same energy-saving suggestions and high-energy consumption alarms. Then, the energy-saving suggestions and high-energy consumption alarms are compared with the energy-saving suggestions and high-energy consumption alarms output by the decision engine layer. If the results are the same, the energy-saving suggestions and high-energy consumption alarms are presented. If the results are different, a reminder is issued to the staff, who then confirm the energy-saving suggestions and high-energy consumption alarms for the second time.

[0102] If the value is not less than the error value, no judgment is made and the energy-saving suggestions and high energy consumption alarms output by the decision engine layer are directly presented;

[0103] For example, current power consumption data: "time": 2024-07-24 10:00:00, energy: 150.0;

[0104] Historical power consumption data: "time": 2024-07-23 10:00:00, energy: 145.0;

[0105] Set an error threshold, such as 5.0, and check whether all differences are less than this error threshold. When the difference is less than the error value, comprehensively analyze the corresponding switch cabinet energy usage status information in the repository, generate energy-saving suggestions and high-energy consumption alarms, such as "turn off unnecessary equipment" and "the current energy consumption is too high, please check the equipment", obtain the energy-saving suggestions and high-energy consumption alarms output by the decision engine layer, compare the results of the comprehensive analysis with the output of the decision engine layer, and if the results are consistent, directly present the energy-saving suggestions and high-energy consumption alarms, that is, display the energy-saving suggestions and high-energy consumption alarms: "turn off unnecessary equipment" and "the current energy consumption is too high, please check the equipment".

[0106] Wherein, the interactive dashboard is used to control the operation of the switch cabinet.

[0107] In summary, data from heterogeneous data sources (environmental sensors, cameras, plug data, etc.) are fused at the appropriate data fusion level and processed to generate actionable, explainable, personalized and persuasive recommendations when appropriate. User responses to the generated recommendations trigger actuators to perform their respective energy-saving actions and provide more personalized future recommendations.

[0108] By initially fusing data from sensors of the same type, we can reduce data redundancy and increase data accuracy. By combining data from different types of sensors, we can extract higher-level information and finally integrate low-level and mid-level fused data to generate comprehensive energy consumption analysis results. After data fusion, we use advanced artificial intelligence algorithms (such as machine learning and deep learning) to analyze the fused data, identify energy consumption patterns, detect anomalies, and predict future energy consumption trends.
