[0026] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0027] Figure 1 The following schematically shows an implementation diagram of a method for constructing a digital twin for quality detection of an intelligent power distribution terminal according to an embodiment of the present invention. Figure 1 As shown, this embodiment provides a method for constructing a digital twin for quality detection of an intelligent power distribution terminal, which is applied to the intelligent power distribution terminal and a detection platform communicatively coupled with the intelligent power distribution terminal. The construction method includes:

[0028] A digital twin object class is created on both the intelligent distribution terminal and the detection platform, and the following sub-object classes are assigned to the digital twin object class: at least one of a protocol consistency test object class, a performance test object class, and a telesignaling and remote control class; the protocol consistency test object class is used to perform protocol consistency testing; the performance test object class is used to perform performance testing; and the telesignaling and remote control class is used to perform telesignaling and remote control testing.

[0029] The above implementation enables the provision of digital twins for both the smart power distribution terminal and the testing platform, achieving a two-level digital twin for smart power distribution terminal testing. By embedding the digital twin in the smart power distribution terminal's embedded software platform for edge computing and then embedding the digital twin in the testing platform, accurate quality testing of the smart power distribution terminal is achieved.

[0030] In some embodiments provided herein, the digital twin object class is an empty object class and includes attribute information. The attribute information includes a unique ID and a terminal type (TType). The unique ID identifies the smart power distribution terminal; each smart power distribution terminal has a unique ID. The terminal type (TType) includes the terminal type or model, which determines the content of the performance test and the test items of the protocol conformance test.

[0031] In some embodiments provided by the present invention, the digital twin object class and the sub-object classes under the digital twin object class are all run on the container of the embedded operating system. The idea of docker is to use the operating system resources to build some applications on it. The advantage of docker is that it is cross-platform, and only one image needs to be built, which can be deployed on different platforms. The image can also be pushed to a remote warehouse to facilitate the construction of the same environment. Running the digital twin object class and the sub-object classes under the digital twin object class in this embodiment based on the container is conducive to the continuous integration and continuous deployment implementation of the digital twin.

[0032] In some embodiments provided by the present invention, the digital twin object class on the detection platform also includes the following sub-object classes: a three-dimensional graphic object class; the three-dimensional graphic object class is used to perform three-dimensional reconstruction and status display of the intelligent power distribution terminal. In the aforementioned embodiments, the structure of the digital twin object class on the detection platform is the same as that on the detection platform, but on the detection platform, in order for users to more intuitively know the quality inspection results of the intelligent power distribution terminal, it is necessary to add a three-dimensional graphic object class. The three-dimensional graphic object class is also a sub-object class of the digital twin object class, which provides a three-dimensional reconstruction function and a status display function. The specific implementation methods of the above functions will be described in detail later.

[0033] In some embodiments provided herein, the three-dimensional reconstruction of the three-dimensional graphic object class includes: scanning the intelligent power distribution terminal from different positions and angles; acquiring and processing three-dimensional point cloud data of the intelligent power distribution terminal, wherein the processing includes at least one of filtering, classification, and edge extraction; and performing three-dimensional reconstruction of the intelligent power distribution terminal based on the processed three-dimensional point cloud data to obtain three-dimensional visual data for display. A comprehensive data model is beneficial for improving the accuracy of quality inspection. Point cloud images are composed of point cloud data, which, in addition to geometric position, may also contain color information. Color information is typically obtained by capturing a color image using a camera, and then assigning color information (RGB) to the corresponding point in the point cloud for the pixel at the corresponding position. Intensity information is obtained by acquiring the echo intensity collected by the laser scanner receiving device. This intensity information is related to the target's surface material, roughness, incident angle, and the instrument's emission energy and laser wavelength. The three-dimensional visual data ultimately obtained through the above steps can be displayed on the main system interface of the inspection platform.

[0034] In some embodiments provided by the present invention, the three-dimensional graphic object class is further configured to: perform different status displays based on at least one of the test results of the protocol consistency test object class, the performance test object class, and the remote control class; the different status displays include at least one of distorted display, colored display, or text prompts. An object corresponding to the smart distribution terminal to be tested is generated through the digital twin object class. The test results of the smart distribution terminal are obtained during the data interaction with the digital twin in the smart distribution terminal and stored in the database. The test results are displayed on the three-dimensional graphic in real time to achieve a what-you-see-is-what-you-get effect. After the test results are displayed in real time, the historical test data of the smart distribution terminal is read from the database based on the standard qualified data and compared in real time. If the protocol consistency does not meet the requirements, an alarm is issued on the screen. If the performance does not meet the requirements, the three-dimensional graphic of the smart distribution terminal is distorted to indicate that the performance of the smart distribution terminal does not meet the requirements. If the remote control does not meet the requirements, the specific abnormal situation pops up on the three-dimensional graphic. Through the above embodiments, the test results can be intuitively displayed on the detection platform through the three-dimensional graphic object class.

[0035] In some embodiments of the present invention, the test results of the protocol consistency test object class, performance test object class, and remote signaling and remote control class are further integrated with the operating condition data of the intelligent power distribution terminal. The integrated data is used to determine the failure probability of the intelligent power distribution terminal. The operating condition data here includes equipment status, real-time load, and electrical measurements. The failure probability of the intelligent power distribution terminal can be predicted using artificial intelligence algorithm models such as deep learning, thereby providing recommendations for future design improvements of the distribution terminal.

[0036] In order to facilitate the understanding and implementation of those skilled in the art, the implementation of the digital twin construction is explained from the perspectives of the smart distribution terminal and the detection platform through the following embodiments.

[0037] The digital twin construction method for the intelligent power distribution terminal is presented in the form of a software app and runs on the container of the terminal's embedded operating system. The construction process is as follows:

[0038] Step 1: After the program starts, use object-oriented thinking to create an empty digital twin object class CTerminalDT and assign it three sub-object classes: the protocol consistency test object class CProtConformTest, the performance test object class CPerformanceTest, and the remote signaling and remote control class CComControl. Also, assign the object class CTerminalDT two attributes: a unique code ID and a terminal type TType.

[0039] Step 2: Based on the terminal type TType and coding ID, such as the protocol consistency test of the distribution transformer terminal TTU, communicate with the testing platform according to the protocol consistency requirements of the corresponding distribution transformer terminal TTU, and determine whether it meets the requirements of the communication protocol; record the results and report the results to the testing platform in real time;

[0040] Step 3: If it is a performance test, complete the performance test through CPerformanceTest, record the results and report the results to the testing platform;

[0041] Step 4: If it is a remote control test, complete the remote control test through CComControl, record the results and report them to the detection platform;

[0042] Step 5: Repeat steps 2 to 5 a total of 10 times, and summarize the results of the 10 protocol consistency tests, performance tests, and remote signaling and remote control tests as historical data and temporarily store them in the smart distribution terminal.

[0043] The digital twin construction method on the detection platform is presented in the form of an independent process software system, running on a PC. It is responsible for the three-dimensional visualization of the intelligent distribution terminal detection, reading and writing databases, displaying detection results, and interacting with the intelligent distribution terminal in real time. The construction process is as follows:

[0044] Step 1: Scan the intelligent power distribution terminal from different positions and angles to obtain 3D point cloud data and store it in the database. Then perform filtering, classification, edge extraction, and 3D reconstruction of the intelligent power distribution terminal, and display it on the system main interface.

[0045] Step 2: Similarly, on the detection platform side, using object-oriented thinking, create an empty digital twin object class CTerminalDT and assign it four sub-object classes: the 3D graphics object class CDisplay, the protocol consistency test object class CProtConformTest, the performance test object class CPerformanceTest, and the remote signaling and remote control class CComControl. The object class CTerminalDT is also assigned two attributes: a unique code ID and a terminal type Ttype.

[0046] Step 3: Generate an object corresponding to the smart distribution terminal to be tested through the CterminalDT class. During data exchange with the lightweight digital twin in the edge-side distribution terminal, the test results of the distribution terminal are obtained and stored in the database. The results are then displayed in real time on a 3D graph, achieving a what-you-see-is-what-you-get (WYSIWYG) effect.

[0047] Step 4: After the test results are displayed in real time, the historical test data of the distribution terminal is read from the database based on the standard qualified data and compared in real time;

[0048] Step 5: If the protocol consistency does not meet the requirements, a screen alarm will be issued. If the performance does not meet the requirements, the three-dimensional graphics of the distribution terminal will be distorted to indicate that the terminal's performance does not meet the requirements. If the remote signaling and remote control do not meet the requirements, the specific abnormal situation will be popped up on the three-dimensional graphics.

[0049] Step 6: If all are qualified, all data related to the smart distribution terminal to be tested will be integrated, and the probability of terminal equipment failure will be predicted through artificial intelligence algorithm models such as deep learning. Suggestions will be given on how to improve the future design of the smart distribution terminal.

[0050] Through the above implementation methods, digital twins for quality inspection with corresponding functions can be constructed on the smart distribution terminal and the detection platform respectively. Among them, the digital twin on the smart distribution terminal is a simple mapping of the smart distribution terminal as a physical entity in the virtual space. This mapping does not include the three-dimensional visual data and historical data of the terminal, but only includes real-time interactive data, reflecting the real-time status of the performance and function of the smart distribution terminal. The digital twin on the detection platform is a complex mapping of the smart distribution terminal as a physical entity in the virtual space. This mapping includes the three-dimensional visual data of the terminal, the terminal test history data and the real-time interactive data with the physical entity of the edge-side smart distribution terminal. It is a more comprehensive expression of the performance and function of the smart distribution terminal.
