For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0087] Currently, energy efficiency analysis mainly uses the traditional energy efficiency analysis system (EMS).

[0088] The inventors recognized that, on the one hand, the system's decentralized software architecture prevented effective data integration across disparate systems. For example, power consumption data, power equipment operating parameters, and equipment environmental parameters were often collected and stored in separate systems by different components, making unified management and analysis difficult. This data silo phenomenon limited the comprehensiveness and accuracy of energy efficiency analysis. Furthermore, the system's inability to reflect dynamic changes in energy consumption in real time prevented managers from promptly identifying energy waste or anomalies, hindering their ability to implement energy optimization measures.

[0089] In order to solve the above problems, the present application provides an energy efficiency analysis method and device based on multi-source data to solve the problems existing in the above-mentioned related technical problems. In an embodiment of the present application, on the one hand, data modeling and standardization processing are performed on the multi-source data of each power device to obtain multi-source standardized data of each power device. Because the data has been modeled and standardized, the differences and inconsistencies between data from different sources are eliminated, so that energy efficiency analysis can be carried out based on a unified and standardized data foundation, eliminating data silos, and not only covering power energy consumption data, but also comprehensively considering equipment operating parameters and equipment environmental parameters, thereby improving the comprehensiveness and accuracy of energy efficiency analysis. On the other hand, the visual display of the dynamic dashboard can reflect the dynamic changes in energy consumption in real time. Managers can view the real-time energy flow diagram and equipment energy efficiency ranking at any time through the client, promptly discover abnormal fluctuations or energy waste in the energy consumption process and take corresponding energy optimization measures, thereby effectively reducing energy consumption, improving energy utilization efficiency, and realizing refined energy management and optimized control. The following uses an exemplary embodiment to explain in detail.

[0090] The following will be combined with the Figure 1 -Attached Figure 6This article details the multi-source data-based energy efficiency analysis method provided in the embodiments of this application. This method can be implemented using a computer program and run on a multi-source data-based energy efficiency analysis device based on the von Neumann architecture. This computer program can be integrated into an application or run as a standalone tool application.

[0091] See Figure 1 , provides a flow chart of an energy efficiency analysis method based on multi-source data for an embodiment of the present application, which is applied to the server. Figure 1 As shown, the method of the embodiment of the present application includes the following steps:

[0092] S101, acquiring power consumption data, equipment operating parameters, and equipment environmental parameters of each power device in the target area according to a preset period to obtain multi-source data of each power device;

[0093] The preset period refers to a pre-set time interval for periodic data collection. The length of the period can be adjusted based on actual needs and application scenarios, such as hourly, daily, or weekly. The target area refers to the specific geographic area or facility area where data collection and analysis is required, such as a factory floor, an office building, or a data center. Power equipment refers to equipment used to generate, transmit, distribute, and use electrical energy, such as generators, transformers, distribution cabinets, motors, and lighting equipment.

[0094] In some embodiments of the present application, during the energy efficiency analysis based on multi-source data, the server will calculate in real time the duration between the current moment and the end moment of the previous analysis. When the duration is equal to the preset period, the server will obtain the power consumption data, equipment operating parameters and equipment environmental parameters of each power equipment in the target area to obtain multi-source data of each power equipment.

[0095] For example, identify the area where data needs to be collected (such as a factory or office building) and all relevant electrical equipment within the area (such as transformers, motors, and lighting systems). Install smart meters or energy consumption monitoring devices and connect them to the circuits of each electrical device. Smart meters can measure parameters such as the device's power consumption and power factor in real time. Install sensors (such as current sensors, voltage sensors, and power sensors) on the equipment to monitor its operating parameters, such as its status, operating time, and load factor, in real time. Install environmental sensors (such as temperature and humidity sensors and pressure sensors) around the equipment. These sensors can monitor the temperature and humidity of the equipment's operating environment in real time.

[0096] S102, performing data modeling and standardization processing on multi-source data of each power device to obtain multi-source standardized data of each power device;

[0097] In some embodiments of the present application, data modeling and standardization are performed on the multi-source data of each power device to obtain the multi-source standardized data of each power device. The process specifically includes: defining the entity relationship data structures corresponding to the power energy consumption data, equipment operating parameters and equipment environmental parameters, and obtaining the energy consumption data structure, equipment data structure and environmental parameter data structure; mapping the power energy consumption data, power equipment operating parameters and equipment environmental parameters of each power device to the energy consumption data structure, equipment data structure and environmental parameter data structure, respectively, and obtaining multi-source data with a unified data structure for each power device; and time-aligning the multi-source data with a unified data structure to obtain multi-source standardized data for each power device.

[0098] Among them, the entity-relationship data structure is a structured framework used to describe various entities in the data (such as power consumption data, equipment operating parameters, and equipment environmental parameters). It helps organize and manage complex data by defining the attributes and structure of the entities. The energy consumption data structure is used to store and manage the data structure of power consumption data, which usually includes attributes such as power identification and power identification. The device data structure is used to store and manage the data structure of equipment operating parameters, including attributes such as equipment status identification, operating time identification, and load rate identification. The environmental parameter data structure is used to store and manage the data structure of equipment environmental parameters, which usually includes attributes such as temperature identification and humidity identification. Time alignment is to adjust data with different timestamps to the same time base to ensure the consistency of data in the time dimension.

[0099] In the embodiment of the present application, by defining the entity relationship data structure of power consumption data, equipment operating parameters, and equipment environmental parameters, and mapping these data to the corresponding energy consumption data structure, equipment data structure, and environmental parameter data structure, the structural unification of multi-source data is achieved. Further, by time-aligning the data, multi-source standardized data is obtained. This process not only standardizes the data format, but also eliminates the problems caused by data source and time differences, providing a high-quality, unified data foundation for subsequent energy consumption analysis, thereby improving the accuracy and reliability of energy efficiency analysis.

[0100] Among them, the energy consumption data structure includes power identification and power identification; the equipment data structure includes equipment status identification, operating time identification and load rate identification; the environmental parameter data structure includes temperature identification and humidity identification.

[0101] In some embodiments of the present application, the power energy consumption data, power equipment operating parameters and equipment environmental parameters of each power equipment are mapped to the energy consumption data structure, the equipment data structure and the environmental parameter data structure respectively, and the specific process of obtaining multi-source data with a unified data structure includes: extracting descriptive information that matches the power identifier and the power identifier from the power energy consumption data of each power equipment; extracting descriptive information that matches the equipment status identifier, the operating time identifier and the load rate identifier from the power equipment operating parameters of each power equipment; extracting descriptive information that matches the temperature identifier and the humidity identifier from the equipment environmental parameters of each power equipment; identifying multiple entity keywords of each extracted descriptive information, and performing entity screening on the multiple entity keywords of each descriptive information to generate attribute values ​​of each descriptive information; converting the attribute values ​​of each descriptive information into the format indicated by the identifier corresponding to each descriptive information to obtain the standard value of each descriptive information; establishing a mapping relationship between the identifier corresponding to each descriptive information and the standard value of each descriptive information to obtain multi-source data with a unified data structure.

[0102] Among them, for example Figure 2 As shown in the figure, a keyword spotting model is pre-configured. The keyword spotting model includes multiple text encoders, an attention network with an attention mechanism, a neural network for labeling and segmenting sequence data, and a keyword output layer. The attention network has 8 attention heads.

[0103] In some embodiments of the present application, the specific process of identifying multiple entity keywords for each extracted descriptive information includes: inputting each extracted descriptive information into multiple text encoders in sequence to convert each descriptive information into a vector representation of a fixed dimension to obtain multiple entity vectors; inputting the multiple entity vectors into an attention network to output word vectors with an attention mechanism; inputting the word vectors into a neural network for labeling and segmenting sequence data to output a keyword label sequence; mapping the keyword label sequence to an entity label through the output layer to obtain multiple entity keywords for each descriptive information.

[0104] A text encoder is a neural network structure used to convert text data into a fixed-dimensional vector representation. Common text encoders include recurrent neural networks. Attention networks are used to dynamically assign weights when processing data, highlighting important information and ignoring irrelevant information. Neural networks used to label and segment sequence data (such as text) are typically used for labeling (such as named entity recognition) and segmentation (such as sentence segmentation).

[0105] For example, each description is converted into a fixed-dimensional vector representation, resulting in multiple entity vectors that retain the semantic characteristics of the description. The attention network outputs word vectors that are assigned attention mechanisms. These word vectors highlight the important parts of the description while ignoring irrelevant information. The neural network outputs a sequence of keyword tags that indicates which words or phrases are keywords.

[0106] In some embodiments of the present application, the specific process of screening multiple entity keywords for each descriptive information and generating attribute values ​​for each descriptive information includes: traversing the target entity keyword from the multiple entity keywords of each descriptive information; calculating the similarity between the target entity keyword and other entity keywords in the multiple entity keywords except the target entity keyword; screening the entity keyword with the largest attribute value from the entity keywords whose similarity is greater than a preset threshold; and using the attribute value of the entity keyword with the largest attribute value as the attribute value of each descriptive information.

[0107] In other embodiments of the present application, data modeling and standardization are performed on the multi-source data of each power device to obtain the multi-source standardized data of each power device. The specific process includes: performing data cleaning on the multi-source data of each power device to obtain a pre-processed multi-source data set; inputting the pre-processed multi-source data set into a preset data structure standardization model; wherein the preset data structure standardization model is obtained by binding a pre-defined energy consumption data structure, a device data structure, and an environmental parameter data structure to a scale window established based on a sliding window algorithm, and the scale window is used to convert the format of the input information according to the bound parameters; outputting the multi-source data with a unified data structure of each power device corresponding to the multi-source standardized data; performing spatiotemporal alignment on the multi-source data with a unified data structure to obtain the multi-source standardized data of each power device.

[0108] In the embodiments of the present application, by binding the energy consumption data structure, device data structure, and environmental parameter data structure to a scale window established based on a sliding window algorithm, the speed and efficiency of data processing can be significantly improved. Data cleaning removes noise and invalid information, reducing the processing burden; the unified data structure simplifies the processing flow and avoids the complex conversion caused by inconsistent formats; the high efficiency of the sliding window algorithm further accelerates the speed of data format conversion; and spatiotemporal alignment ensures the consistency of data in time and space dimensions, providing high-quality data support for subsequent analysis.

[0109] S103, generating energy consumption analysis results of each power device based on multi-source standardized data;

[0110] In some embodiments of the present application, the specific process of generating energy consumption analysis results of each power equipment based on multi-source standardized data includes: obtaining predefined energy efficiency standard values; wherein the predefined energy efficiency standard values ​​include standard energy consumption intensity, standard equipment efficiency, standard energy utilization rate, and standard carbon emission intensity; determining the actual energy consumption intensity, actual equipment efficiency, actual energy utilization rate, and actual carbon emission intensity of each power equipment based on multi-source standardized data; comparing the deviation values ​​between the standard energy consumption intensity, standard equipment efficiency, standard energy utilization rate, and standard carbon emission intensity and the actual energy consumption intensity, actual equipment efficiency, actual energy utilization rate, and actual carbon emission intensity of each power equipment to obtain the energy consumption analysis results of each power equipment.

[0111] In one possible implementation, the standard energy intensity is, for example, 50 kWh / ton. The standard equipment efficiency is, for example, 90%. The standard energy utilization rate is, for example, 85%. The standard carbon emission intensity is, for example, 0.5 kg CO2 / kWh. At this point, actual operating data for a motor is obtained: actual energy intensity: 60 kWh / ton. Actual equipment efficiency: 88%. Actual energy utilization rate: 82%. Actual carbon emission intensity: 0.6 kg CO2 / kWh. Comparing the standard and actual values, the deviation is calculated: Energy intensity deviation: Actual value 60 kWh / ton - Standard value 50 kWh / ton = +10 kWh / ton. Equipment efficiency deviation: Actual value 88% - Standard value 90% = -2%. Energy utilization rate deviation: Actual value 82% - Standard value 85% = -3%. Carbon emission intensity deviation: Actual value 0.6 kg CO2 / kWh - Standard value 0.5 kg CO2 / kWh = +0.1 kg CO2 / kWh. Analysis shows that the motor's actual energy consumption intensity exceeds the standard by 10 kWh / ton, indicating high energy consumption and potential for energy savings. The actual equipment efficiency is 2% below the standard, indicating energy losses during energy conversion. The actual energy utilization rate is 3% below the standard, indicating that the equipment is not fully utilizing input energy during operation. The actual carbon emission intensity is 0.1 kg CO2 / kWh above the standard, indicating that the equipment has a high carbon emission level and a significant environmental impact.
