[0028] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0030] Figure 1 It is a flow chart of a power signal transmission method provided in an embodiment of the present invention. This embodiment is applicable to the case of power signal transmission, and is particularly applicable to the case of power signal transmission in a long-distance transmission line. The method can be executed by a power signal transmission device provided in an embodiment of the present invention, and the device can be implemented by software and / or hardware, and the device can be integrated in an electronic device, and the electronic device can be various user terminals or servers.

[0031] See also Figure 1 The method of the embodiment of the present invention specifically includes the following steps:

[0032] S110. For an embedded device deployed on a transmission line and an adjacent device adjacent to the embedded device, the embedded device is used to compress the power signal based on a compression parameter to obtain a compressed signal, and the compressed signal is transmitted to the adjacent device, wherein the adjacent device is another embedded device.

[0033] The power signal may be understood as a signal to be transmitted on a transmission line, and in particular, may be understood as a signal to be transmitted on a long-distance transmission line.

[0034] In an embodiment of the present invention, optionally, before transmitting the power signal, an adaptive signal processing algorithm may be used to pre-process the collected power signal according to the power system's requirements for the power signal transmission quality, such as denoising, filtering, and feature extraction, to obtain an optimized power signal.

[0035] Specifically, according to the power system's requirements for the quality of power signal transmission, a wavelet transform algorithm is used to denoise the collected power signal to remove the high-frequency noise interference components in the power signal, and then wavelet reconstruction is performed to obtain the denoised power signal. Then, a Kalman filter algorithm is used to adaptively filter the denoised power signal, and the filter parameters are adaptively adjusted to suppress the random noise in the power signal to obtain a filtered power signal. Then, an empirical mode decomposition algorithm is used to extract the eigenmode function and instantaneous frequency characteristic parameters of the filtered power signal to obtain signal characteristics, and the signal characteristics are used as the power signal for subsequent steps.

[0036] Optionally, considering that the integrity of the power signal is susceptible to electromagnetic interference, the power signal can be pre-processed through electromagnetic shielding and isolation technology to reduce the impact of electromagnetic interference on the integrity of the power signal. On this basis, further, the residual electromagnetic interference components in the power signal can be automatically detected and suppressed through an adaptive filtering algorithm to further reduce the impact of electromagnetic interference on the integrity of the power signal.

[0037] A plurality of embedded devices are deployed on the transmission line. In an embodiment of the present invention, the embedded devices may be pre-deployed optionally in the following manner: obtaining the topological structure of the power network corresponding to the power system and parameter information of the transmission line, and for a complex network in which the number of network nodes exceeds a preset number and the total length of the transmission line exceeds a preset distance, using a clustering algorithm to divide the network into multiple areas, and determining the position coordinates of key nodes at the electrical distance center node of each area, so as to deploy an embedded device at each key node based on each position coordinate and using a distributed deployment strategy.

[0038] Here, any embedded device X among multiple embedded devices is taken as an example, and the adjacent device can be understood as another embedded device Y adjacent to the embedded device X. Using the embedded device X, the power signal is compressed based on the compression parameter to obtain a compressed signal. In an embodiment of the present invention, optionally, the compression parameter can be a compression ratio; of course, it can also be other parameters related to compression, which are not specifically limited here. Exemplarily, a wavelet compression algorithm can be used to compress the power signal based on the compression parameter to obtain a compressed power signal (i.e., a compressed signal). Further, the compressed signal is transmitted to the adjacent device, for example, the compressed signal can be transmitted to the adjacent device through the high-speed communication interface of the embedded device X.

[0039] S120. Decompress the received compressed signal using an adjacent device to obtain a decompressed signal, and evaluate the signal quality of the decompressed signal to obtain an evaluation result.

[0040] The received compressed signal is decompressed by using adjacent devices to obtain a decompressed signal. For example, when a wavelet compression algorithm is used to compress the power signal, a wavelet decompression algorithm can be used to decompress the compressed signal to obtain a decompressed signal. In certain cases, the decompressed signal is substantially equivalent to the original power signal.

[0041] The signal quality of the decompressed signal is evaluated to obtain an evaluation result. For example, considering that when the power signal is transmitted on a long-distance transmission line, power signal attenuation and distortion are likely to occur, which will affect the signal quality of the power signal. Therefore, an evaluation model of power signal attenuation and distortion can be used to evaluate the signal quality of the decompressed signal using a convolutional neural network algorithm to obtain an evaluation result.

[0042] S130. When it is determined according to the evaluation result that the signal quality is unqualified, the compression parameters are adjusted and updated, and the process returns to execute S110.

[0043] The evaluation result obtained through the above steps can characterize whether the signal quality is qualified. In the embodiment of the present invention, optionally, the evaluation result can be represented by an evaluation score, on which basis, whether the signal quality is qualified can be determined according to the numerical relationship between the evaluation score and a preset score threshold.

[0044] When the signal quality is unqualified, it means that the compressed signal based on the compression parameters is lossy compression and is unusable, and the compression parameters need to be adjusted for recompression.

[0045] S140. Transmit the compressed signal to an application node of the power system where the transmission line is located.

[0046] Among them, when the evaluation result indicates that the signal quality is qualified, it means that the compressed signal compressed based on the compression parameters is basically lossless compression and can be used. Therefore, the compressed signal can be transmitted to the application node of the power system, which is the power system where the transmission line is located.

[0047] The technical solution of the embodiment of the present invention is aimed at an embedded device deployed on a transmission line and an adjacent device adjacent to the embedded device (i.e., another embedded device). By utilizing the embedded device, a power signal is compressed based on a compression parameter to obtain a compressed signal, and the compressed signal is transmitted to the adjacent device. During the transmission process, the transmission quality of the compressed signal is less likely to be affected than that of the original power signal. Then, the adjacent device is used to decompress the received compressed signal to obtain a decompressed signal, and the signal quality of the decompressed signal is evaluated to obtain an evaluation result to confirm whether the previous power signal compression process is lossy compression or lossless compression. On this basis, if the evaluation result indicates that the signal quality is unqualified, it indicates lossy compression, then the compression parameters are adjusted, and the power signal is compressed again based on the adjusted compression parameters. If the evaluation result indicates that the signal quality is qualified, it indicates lossless compression, then the current compressed signal can be transmitted to the application node of the power system where the transmission line is located to complete the transmission process of the power signal corresponding to the compressed signal. The above technical solution, on transmission lines, especially long-distance transmission lines, compresses the power signal, especially compresses it into a compressed signal with qualified signal quality, and transmits the compressed signal, thereby reducing the attenuation and distortion of the power signal during long-distance transmission and improving the transmission quality of the power signal.

[0048] On this basis, an optional technical solution is to evaluate the signal quality of the decompressed signal and obtain an evaluation result, including:

[0049] Using error correction coding technology, the decompressed signal is encoded to obtain an error correction code;

[0050] The error correction code is compared with the power signal, and when it is determined that there is a bit error according to the comparison result, the bit error is corrected to obtain a corrected signal;

[0051] By comparing the corrected signal with the power signal, an evaluation result of the signal quality of the decompressed signal is obtained.

[0052] The above technical solution realizes effective evaluation of signal quality through error correction coding technology.

[0053] Another optional technical solution is that before the power signal is compressed based on the compression parameter to obtain the compressed signal, the power signal transmission method further includes:

[0054] Based on the adaptive sampling rate adjustment strategy, the sampling rate is adaptively adjusted according to the frequency adjustment and energy distribution of the power signal to obtain the target sampling rate;

[0055] Based on the target sampling rate, the power signal is sampled to obtain a sampled signal, and the power signal is updated according to the sampled signal.

[0056] Among them, taking into account the current situation that embedded devices have limited computing and storage resources, in order to ensure high-speed processing of power signals by embedded devices, a target sampling rate that matches the power signal can be determined. For example, for power signals with lower frequencies, the target sampling rate can be reduced to 1kHz, and for power signals with higher frequencies, the target sampling rate can be increased to 10kHz; then, based on the target sampling rate, the power signal is sampled to obtain a sampled signal, thereby reducing the signal amount while ensuring the signal quality of the power signal, thereby effectively improving the signal processing efficiency and reliability of the embedded device.

[0057] On this basis, optionally, considering that embedded devices are likely to work in harsh environments, measures such as sealing, waterproofing, dustproofing and shockproofing can be taken to enhance the environmental adaptability of embedded devices and reduce operation and maintenance costs.

[0058] Figure 2 It is a flow chart of another power signal transmission method provided in an embodiment of the present invention. This embodiment is optimized based on the above-mentioned technical solutions. In this embodiment, optionally, before the power signal is compressed based on the compression parameter to obtain the compressed signal, the above-mentioned power signal transmission method may also include: inputting the power signal into a pre-trained power signal enhancement model, so as to utilize the power signal enhancement model to analyze the power signal to obtain the transmission environment of the power signal, and adaptively enhance the power signal according to the transmission environment; and update the power signal according to the adaptive enhancement result. Among them, the explanations of the terms that are the same or corresponding to the above-mentioned embodiments are not repeated here.

[0059] See also Figure 2 The method of this embodiment may specifically include the following steps:

[0060] S210. For the power signal to be transmitted, the power signal is input into a pre-trained power signal enhancement model, so as to utilize the power signal enhancement model to obtain the transmission environment of the power signal by analyzing the power signal, and adaptively enhance the power signal according to the transmission environment.

[0061] Among them, the power signal enhancement model can be understood as a deep learning model for enhancing power signals. In an embodiment of the present invention, optionally, the power signal enhancement model can be pre-trained in the following manner: obtain historical power signals under harsh environments, pre-process the historical power signals to remove obvious outliers and noise interference, and obtain pre-processed power signals; then, extract the time domain features, frequency domain features, and spatial domain features of the pre-processed power signals, and construct feature vectors as inputs of the deep learning model; use a deep learning model combining a convolutional neural network and a long short-term memory network to train the feature vectors, learn the feature patterns of historical power signals under different harsh environments (such as extreme weather such as lightning and heavy rain), and thereby establish a power signal enhancement model.

[0062] The power signal is input into the power signal enhancement model, so that the power signal enhancement model can be used to analyze the power signal to obtain the transmission environment of the power signal, and then the power signal can be adaptively enhanced according to the transmission environment. For example, the adaptive enhancement process of the power signal can be achieved by adjusting the amplitude of the power signal, reconstructing the spectrum and correcting the phase operation.

[0063] S220. Update the power signal according to the adaptive enhancement result.

[0064] S230. For an embedded device deployed on a transmission line and an adjacent device adjacent to the embedded device, the embedded device is used to compress the power signal based on a compression parameter to obtain a compressed signal, and the compressed signal is transmitted to the adjacent device, wherein the adjacent device is another embedded device.

[0065] S240. Decompress the received compressed signal using an adjacent device to obtain a decompressed signal, and evaluate the signal quality of the decompressed signal to obtain an evaluation result.

[0066] S250. When it is determined that the signal quality is unqualified according to the evaluation result, the compression parameters are adjusted and updated, and the process returns to execute S230.

[0067] S260. Transmit the compressed signal to the application node of the power system where the transmission line is located.

[0068] The technical solution of the embodiment of the present invention takes into account that the transmission quality of the power signal is very easily affected by the harsh environment, and therefore uses a power signal enhancement model to enhance the power signal, thereby assisting the transmission process of the power signal in the harsh environment and ensuring the continuity and reliability of the power signal transmission.

[0069] On this basis, an optional technical solution is to transmit the compressed signal to the application node of the power system where the transmission line is located, including:

[0070] adjusting the routing selection strategy according to the transmission environment output by the power signal enhancement model, and selecting a transmission path combination on the transmission line according to the adjusted routing selection strategy;

[0071] Based on each transmission path in the transmission path combination, the compressed signal is transmitted to the application node of the power system where the transmission line is located.

[0072] Among them, in order to further ensure the continuity and reliability of power signal transmission in harsh environments, the optimal transmission path combination on the transmission line can be selected for the compressed signal (i.e., the compressed power signal) according to the transmission environment output by the power signal enhancement model, so as to transmit the power signal based on the transmission path combination, thereby realizing multi-path redundant transmission of the power signal, thereby ensuring the continuity and reliability of transmission.

[0073] On this basis, optionally, based on each transmission path in the transmission path combination, the compressed signal is transmitted to the application node of the power system where the transmission line is located, including:

[0074] For each transmission path, in the process of transmitting the compressed signal through the transmission path to the application node of the power system where the transmission line is located, collecting performance indicator data on the transmission path;

[0075] Perform anomaly detection on performance indicator data and generate a fault handling strategy if a transmission failure risk is determined based on the anomaly detection results;

[0076] According to the fault handling strategy, the transmission path combination is adjusted, and the compressed signal is transmitted to the application node according to the adjusted transmission path combination.

[0077] In the process of power signal transmission, the performance index data on the transmission path is collected in real time. The performance index data may be, for example, delay, jitter, and packet loss rate, so as to determine whether there is an abnormal fault risk in the signal transmission process on the transmission path. If so, the transmission path combination can be adjusted in time, so that the transmission path can be reconstructed and optimized to achieve active avoidance and recovery of faults.

[0078] On this basis, in order to better understand the above-mentioned technical solutions as a whole, the following can be combined with specific examples to illustrate them. For example, the specific implementation process is as follows:

[0079] S1. According to the requirements of the power system for the power signal transmission quality, an adaptive signal processing algorithm can be used to pre-process the collected power signal, such as performing denoising, filtering and feature extraction, to obtain an optimized power signal.

[0080] S2. In view of the characteristics of the expansion and complexity of power networks and long-distance transmission lines, distributed embedded devices are deployed to process and compress the optimized power signals on-site, thereby reducing the attenuation and distortion of power signals during long-distance transmission.

[0081] S3. Integrate the power signal integrity detection module in the distributed embedded device, use error correction coding technology to monitor the compressed and transmitted power signal in real time, and automatically correct it when errors occur.

[0082] S4. To address the impact of electromagnetic interference on the integrity of power signals, electromagnetic shielding and isolation technology is used in the hardware design of distributed embedded devices, and an adaptive interference suppression mechanism is introduced in the software algorithm to perform frequency domain filtering and time domain smoothing on the error-corrected power signals.

[0083] S5. To address the problem of power signal transmission in harsh environments, a signal enhancement algorithm based on deep learning is adopted. By training a large number of historical power signals, the characteristic patterns of historical power signals in different harsh environments are learned, and the power signals that have been suppressed by electromagnetic interference are adaptively enhanced and restored, including power signal amplitude adjustment, spectrum reconstruction and phase correction.

[0084] S6. In harsh environments, the enhanced and restored power signals are transmitted through multi-path redundant transmission and adaptive routing selection technology; at the same time, a fault prediction model based on machine learning can be introduced to analyze the power signals during the transmission process to identify and locate potential transmission failure risks in advance.

[0085] S7. In order to solve the problems of limited computing and storage resources and harsh working environment of distributed embedded devices, lightweight signal processing algorithms and data compression technologies can be used to optimize the power signals at each processing stage, including adaptive adjustment of the power signal sampling rate, wavelet transform compression and differential coding. At the same time, the impact of harsh environment can be considered in the hardware selection and packaging design of distributed embedded devices.

[0086] The above example effectively improves the integrity and accuracy of power signal transmission on long-distance high-voltage transmission lines by adopting adaptive signal processing, error correction coding, electromagnetic interference suppression, and signal enhancement technology based on deep learning, thereby significantly improving the transmission quality of power signals; at the same time, in harsh environments, this example can ensure the continuity and reliability of power signal transmission, thereby avoiding errors and interruptions and enhancing the reliability of the power system; in addition, by adopting lightweight algorithms and data compression technology, the resource utilization of embedded devices is optimized, so that power signals can be efficiently collected, accurately analyzed, and fed back in real time under limited hardware conditions; combined with multi-path redundant transmission and adaptive routing selection technology, as well as transmission fault prediction based on machine learning, this example not only improves the efficiency of fault location and maintenance, but also improves the real-time and flexibility of the power system; in view of the harsh working environment of embedded devices, this example enhances environmental adaptability and reduces operation and maintenance costs through sealing, waterproofing, dustproofing, and shockproofing measures.

[0087] In summary, this example provides strong support for the stable operation of complex power networks and helps to ensure energy security and the stability of power supply.

[0102] The compressed signal transmission unit can be used to transmit the compressed signal to the application node of the power system where the transmission line is located based on each transmission path in the transmission path combination.

[0103] On this basis, optionally, a compression signal transmission unit is specifically used to:

[0104] For each transmission path, in the process of transmitting the compressed signal through the transmission path to the application node of the power system where the transmission line is located, collecting performance indicator data on the transmission path;

[0105] Perform anomaly detection on performance indicator data and generate a fault handling strategy if a transmission failure risk is determined based on the anomaly detection results;
