[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 , which is the first embodiment of the present invention, provides an intelligent fault recording detection system, which includes an acquisition module for acquiring target signals in the power system.

[0031] Furthermore, the target signal includes a real-time signal and a high-speed digital signal.

[0032] It should be noted that the real-time signals and high-speed digital signals of the power system are collected through analog quantity acquisition boards and switch quantity acquisition boards.

[0033] The FPGA module is used to preprocess the collected target signal to form a first target signal, wherein the preprocessing is high-speed preprocessing.

[0034] It should be noted that the parallel processing capability of the FPGA module is used to pre-process the collected signal data to ensure the accuracy and synchronization of the data.

[0035] Further, the FPGA module is connected to the acquisition module;

[0036] Preprocessing includes filtering the target signal, signal format conversion and time synchronization.

[0037] The AMP module is used to analyze the first target signal, perform timing calculation and real-time processing on it, and form a second target signal.

[0038] Furthermore, the AMP module also includes recording the second target signal into a non-volatile storage device.

[0039] Furthermore, the AMP module includes 2 bare cores and 2 real-time system cores.

[0040] It should be noted that the bare core is used to receive and parse the high-speed recording data from the FPGA module (including SV (sampled value), GOOSE (generic object oriented event) and analog switch data, as well as statistical network traffic) and forward the parsed data to the real-time system core. The first real-time system core further performs data analysis, traffic monitoring and event processing on the parsed data, completes the timing calculation of the data, and transmits the processed data to the second real-time system core. The second implementation system core (RTOS core) is responsible for recording and uploading the data. In addition, this part also records the data in a non-volatile storage device, and through the data exchange function, enables the SMP module to read and process the data.

[0041] The SMP module is used to perform in-depth analysis and compression processing on the second target signal to form a third target signal.

[0042] Furthermore, the AMP module and the SMP module are connected via a data exchange module.

[0043] Furthermore, the data exchange module adopts high-speed data exchange technology of PCIe (Peripheral Component Interconnect Express) or network.

[0044] It should be noted that the data exchange module is also connected to the storage device to achieve high-speed data exchange between modules and avoid resource conflicts.

[0045] Furthermore, the SMP module contains a 4-core processor and runs the Linux operating system.

[0046] The display module is used to receive and display the third target signal.

[0047] It should be noted that the first core processor quickly compresses the recording data to reduce the pressure of data storage and transmission; the second core processor generates fault and steady-state recording files and organizes the data format for subsequent analysis; the third and fourth core processors are responsible for in-depth analysis of data, execution of machine learning algorithms, data upload and management. In addition, NPU (neural network processor) chips can be integrated to accelerate deep learning and pattern recognition algorithms, and support advanced applications such as traveling wave ranging and low current grounding. And remote communication: communicate with the display module and remote service through the network interface to realize data upload and system update.

[0048] Furthermore, the display module allows the user to configure system parameters.

[0049] It should be noted that the display module helps users to intuitively understand the operating status of the power system, and allows users to configure system parameters and adjust monitoring and analysis strategies. In addition, it can also monitor the operating status of each unit of the entire system and provide alarm and log functions.

[0050] When in use, the system first collects real-time signals and high-speed digital signals in the power system through the acquisition module. These raw data are then transmitted to the FPGA module, which uses its parallel processing capabilities to perform high-speed preprocessing on the data, including filtering, data format conversion and time synchronization, to ensure the accuracy and consistency of the data. Then, the data preprocessed by the FPGA module is received through multiple heterogeneous multi-processing cores of the AMP module, and real-time data processing and timing calculations are performed, including data analysis, flow monitoring and event processing. The processed data is recorded in a non-volatile storage device and transmitted to the SMP module through the network or PCIe high-speed data exchange technology. The symmetric multi-processing core of the SMP module further analyzes, compresses, stores and uploads the data. At the same time, it is preferred to integrate an NPU chip to accelerate deep learning and pattern recognition algorithms and support advanced applications. Finally, the display module is responsible for displaying the processed data to the user in real time, while allowing the user to configure system parameters and adjust monitoring strategies, as well as monitor the operating status of each unit of the system. The entire system realizes high real-time, high versatility and high data security of power system fault recording detection through a multi-host high-speed data exchange architecture.

[0051] In summary, the beneficial effect of the intelligent fault recording detection system of the present invention is that through multi-host high-speed data exchange and multi-core processing architecture, high real-time monitoring and response of power system faults are achieved, ensuring the rapid capture and processing of fault information. The system adopts a modular design, has high versatility and scalability, can be flexibly configured to meet different needs, and is compatible with multiple processor architectures to reduce costs. The application of non-volatile storage media improves the security and reliability of data and prevents data loss. The collaborative work of multiple hosts reduces the risk of single point failures and enhances the fault tolerance of the system. The system also supports intelligent functions such as advanced data recognition and deep learning optimization, which can efficiently run complex algorithms and improve computing efficiency and accuracy. High-speed interconnection technology ensures high-performance and low-latency communication capabilities to meet the needs of real-time transmission of large amounts of data. Flexible system topology allows for future expansion of the scale and functional upgrade of power systems, while standardized interfaces and protocols ensure strong compatibility with other systems or equipment while reducing maintenance and upgrade costs.

[0055] S2. Process the target signal through the FPGA module, AMP module and SMP module in sequence.

[0056] S3. Display the processed target signal through a display module.

[0057] In summary, the beneficial effect of the intelligent fault recording detection system of the present invention is to efficiently collect real-time signals and high-speed digital signals in the power system through the acquisition module, and use the FPGA module to perform preliminary high-speed preprocessing and synchronization to ensure the accuracy and real-time performance of the data. Then, the AMP module processes the data in real time and performs timing calculations, while the SMP module is responsible for in-depth analysis and data compression, storage and upload, thereby achieving rapid monitoring and response to power system faults. Finally, the processed data is displayed in real time through the display module, providing users with intuitive system operation status and fault information, which not only improves the real-time and accuracy of fault detection, but also enhances the versatility and scalability of the system, while ensuring the security and reliability of the data and reducing maintenance and upgrade costs.
