The general idea is as follows: Based on the problems existing in the prior art, the utility model provides a data processing device for the Power Internet of Things based on cloud-edge collaboration, comprising an edge layer 1, a network layer, and a cloud server 2. The edge layer 1 comprises an industrial computer 11 and an edge server 12, the network layer comprises Ethernet switches 3 and wireless base stations 4. The network layer is connected to an intelligent terminal 5.

[0017] The industrial computer 11 and the edge server 12 are connected via network cables. The edge layer 1 is connected to the Ethernet switch 3 via network cables. Both the edge layer 1 and the cloud server 2 are equipped with a wireless communication module. The edge layer 1 communicates with the wireless base station 4 via wireless signals.

[0018] The Ethernet switch 3 is connected to the cloud server 2 via fiber optic cable, and the cloud server 2 communicates with the wireless base station 4 via wireless signals. Both the edge layer 1 and the cloud server 2 are arranged with a key management module. Edge Layer 1:

[0019] Industrial computer 11: Receives the power consumption data sent from smart terminals 5, covering current, voltage, power, temperature, energy consumption, usage time, etc., to perform preprocessing on these data, such as data cleaning to remove noise and outliers caused by sensor failures or interference. A simple filtering process is performed, the data curve is smoothed to highlight the main features, improving data quality and reducing subsequent processing complexity. The processed data is transmitted to the edge server 12 via a network cable.

[0020] Edge server 12: receives and stores the data transmitted from the industrial computer 11, and then further processes and filteres these data according to predetermined rules, quickly judging whether there is an abnormality in parameters with high real-time requirements, such as the current operating status of the device, and issuing an alarm signal, while storing and sorting data requiring long-term analysis, such as the historical operating data of the device, so that only the essential statistical information and analysis results are uploaded to the cloud server 2, thereby reducing the amount of data transmission; Network layer:

[0021] Ethernet switch 3: Connects to edge layer 1 via network cable, and transmits the data processed by edge layer 1 to cloud server 2 via fiber optic cable. A wired communication link is established between edge layer 1 and cloud server 2 to ensure stable and efficient data transmission;

[0022] Wireless base station 4: The edge layer 1 communicates with the wireless base station 4 via a wireless signal, and the cloud server 2 also communicates with the wireless base station 4 via a wireless signal. The wireless base station 4 provides a wireless communication forwarding service between the edge layer 1 and the cloud server 2 to increase the flexibility of data transmission and meet the data transmission requirements in different scenarios;

[0023] Cloud Server 2: Receives the data uploaded from Edge Layer 1 and uses its own powerful computing and analysis capabilities to perform in-depth processing and analysis of the data through techniques such as big data analysis and AI models, and extract potential information from the data, such as predicting the probability of power equipment failures, analyzing energy load trends, and evaluating the efficiency of the power system, and provides support for power system management and decision-making based on the analysis results;

[0024] Intelligent terminal 5: Data collection device such as a smart meter, is responsible for collecting energy customer data, including current, voltage, power, temperature, energy consumption, usage time, etc., has a wireless communication module itself, and sends the data either wirelessly or via Ethernet to the industrial computer 11, which is the source of all data processing and provides basic information for subsequent data processing and analysis;

[0025] Wireless communication module: Installed in the edge layer 1 and the cloud server 2, in combination with the wireless base station 4, enables wireless communication between the edge layer 1 and the cloud server 2, which makes data transmission more flexible and can adapt to different environments and application scenarios;

[0026] Key management module: Installed in the edge layer 1 and the cloud server 2 to manage the keys during data transmission, so that the security of the data during transmission is ensured through encryption, decryption, etc. to protect the data from theft and tampering, thereby ensuring the confidentiality and integrity of the Power Internet of Things data. How it works:

[0027] Step 1, the intelligent terminal 5 is responsible for collecting power consumption data of the power consumer, including data such as current, voltage, power, temperature, electricity, power consumption time, etc., which are sent to the industrial computer 11. After the data is collected, the industrial computer 11 immediately preliminarily processes it. This includes data cleaning and removal of noise and outliers generated by factors such as sensor errors, interference, performing a simple filtering process, smoothing the data curve and highlighting the main features of data. Preprocessing can improve the data quality to reduce the complexity of subsequent processing. The preprocessed data is transmitted to the edge server 12 via a network cable.The edge server 12 stores the data and simultaneously performs further data processing and selection according to preset rules. For example, for some parameters with high real-time requirements, such as the real-time operating status of the equipment, the edge server 12 can make a quick judgment, and once an abnormal situation is found, an early warning signal is immediately issued. And for some data that requires long-term analysis, such as the historical operating data of the equipment, the edge server 12 stores and sorts the data, so that only the most important statistical information and analysis results are uploaded to the cloud server 2, thereby reducing the amount of data transmission. With its powerful computing and analysis capabilities, the cloud server 2, after receiving the data uploaded from the edge layer 1, performs in-depth processing and analysis of the data.Through techniques such as big data analysis and AI models, the cloud server 2 can extract the potential information behind the data, such as predicting the failure probability of power equipment, analyzing the change trend of power load, evaluating the operating efficiency of the power system, etc., and the cloud server 2 provides support for the management and decision-making of the power system based on the analysis results;

[0028] In step 2, edge layer 1 is connected to Ethernet switch 3 via a network cable, and Ethernet switch 3 is then connected to cloud server 2 via an optical fiber. This wired transmission method is suitable for scenarios with high data transmission volume and high real-time requirements, ensuring the stability and high speed of data transmission. Both edge layer 1 and cloud server 2 are equipped with a wireless communication module. Edge layer 1 can communicate with wireless base station 4 via wireless signals, which then forwards the data to cloud server 2. At the same time, edge layer 1 and cloud server 2 can also communicate directly with each other via wireless signals.The wireless transmission method has the advantages of high flexibility and convenient deployment, which is suitable for some scenarios where laying cable networks is difficult.
