[0038] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0039] Existing power equipment monitoring devices can often only monitor a single device, and the monitoring function is relatively simple, which cannot meet the needs of comprehensive monitoring of the power system.

[0040] Therefore, please refer to Figure 1 The present invention provides a multi-channel panoramic monitoring platform variable visualization monitoring device, including the following components:

[0041] A multi-channel monitoring unit, including multiple monitoring modules, each monitoring module is used to monitor a key parameter of an electric power device in real time;

[0042] A data transmission unit, used to transmit the data collected by each monitoring module to the monitoring host;

[0043] The monitoring host is used to receive and process the data of each monitoring channel, and store and display the data;

[0044] The panoramic monitoring unit is connected to the monitoring host via wireless data. After receiving the data, it builds the analysis model algorithm in sequence, performs panoramic monitoring of the entire power system of the monitoring host, and simultaneously makes a judgment on whether the status is abnormal;

[0045] The alarm unit is electrically connected to the panoramic monitoring unit. When the panoramic monitoring unit determines that the state is abnormal, the signal triggers the alarm unit to send out an alarm signal;

[0046] A power supply unit, which provides working power for the device;

[0047] Communication interface, used for data communication with external systems.

[0048] Specifically, the multi-channel monitoring unit is used to monitor the corresponding key parameters in real time, including:

[0049] Voltage monitoring module, used to monitor voltage parameters of power equipment;

[0050] Temperature monitoring module, used to monitor the thermal status of power equipment;

[0051] Vibration monitoring module, used to monitor the vibration of power equipment;

[0052] Sound monitoring module, used to monitor the sound signals of power equipment;

[0053] The image monitoring module is used to collect circumferential image information of power equipment in real time.

[0054] It should be noted that the voltage monitoring module, temperature monitoring module, vibration monitoring module, sound monitoring module and image monitoring module involved in the present invention all use existing commonly used basic electrical components for data collection, and no unnecessary elaboration is made here.

[0055] Furthermore, a preprocessing unit is embedded in the monitoring host to perform data preprocessing on each parameter data;

[0056] Among them, data preprocessing specifically includes: cleaning, denoising and normalization.

[0057] The data preprocessing steps are the application of existing conventional data processing steps, which are briefly described below:

[0058] 1. Data cleaning:

[0059] Identify and handle missing values: There may be missing data points in a dataset, which may be caused by equipment failure, data transmission errors, or other reasons. Methods for handling missing values ​​include filling missing values ​​(for example, using the mean, median, or mode), deleting records with missing values, or using interpolation methods (such as linear interpolation or spline interpolation) to estimate missing values.

[0060] Identify and handle outliers: Outliers may be caused by measurement errors, equipment failures, or abnormal operations. Methods for handling outliers include identifying outliers using box plots (IQR) or other statistical methods and considering removing or replacing these values.

[0061] Data transformation: For non-numeric data, data transformation, such as encoding or normalization, may be required to facilitate subsequent analysis and modeling.

[0062] 2. Data denoising:

[0063] Time series smoothing: Use techniques such as moving average, low-pass filter, wavelet filter, etc. to smooth time series data to reduce the impact of noise.

[0064] Frequency domain filtering: The time series data is converted to the frequency domain through Fourier transform, and then the frequency domain filter is used to remove the unnecessary frequency components, and then it is returned to the time domain through inverse transform.

[0065] Kalman Filter: The Kalman filter is an efficient recursive filter that is able to estimate the state of a linear dynamic system in the presence of noise.

[0066] 3. Data normalization:

[0067] Linear normalization: Scale the data to a fixed range, such as [0,1] or [-1,1].

[0068] Logarithmic Normalization: For log-transformed data, log normalization can reduce the proportional differences in the data.

[0069] Standardization: Standardization is the process of scaling the data to a normal distribution with a mean of 0 and a standard deviation of 1.

[0070] It should be noted that the image monitoring module specifically includes high-definition cameras for three angles of view: forward, rear and downward, to achieve panoramic monitoring.

[0071] It should be additionally explained that the image monitoring module uses an intelligent recognition algorithm to obtain the number and size of foreign objects at the current judgment moment based on the high-definition camera.

[0072] In addition, in addition to the common intelligent recognition algorithms on the existing market, the present invention also provides a set of optimized recognition algorithms;

[0073] The present invention mainly uses image recognition algorithms based on deep learning to identify them. These include image classification algorithms, image segmentation algorithms, target detection algorithms, moving target recognition algorithms, etc. based on deep learning. Figure 3 .

[0074] In order to enable deep learning models to perform inference in edge devices, the research team studied domestic and foreign literature and combined it with existing technologies to confirm the deployment and implementation path of the algorithm, namely: adopt a lightweight model structure and use a pruning algorithm to prune the model. On this basis, the model is quantized to further reduce the model parameters.

[0075] The operation of identifying hidden dangers in the present invention is mainly carried out around deep learning algorithms. The following is a detailed explanation of the image algorithm based on deep learning and the theory of lightweight deployment of deep learning. The image recognition algorithm based on deep learning essentially uses a deep learning neural network to extract the features of existing pictures, learn the correlation and distinction between different targets, and convert them into parameters and store them in the constructed artificial neural network. When faced with new data, the learned parameters are used to identify new pictures.

[0076] Deep learning is based on artificial neural networks, which usually contain multiple hidden layers and a large number of neurons. Through learning and training, the network's weights and bias parameters are continuously optimized to achieve more accurate prediction and classification tasks. With the continuous development of neural networks, special neural network structures such as convolutional neural networks (CNN) and recurrent neural networks (RNN) have emerged. In this technology project, most defect detection uses convolutional neural networks to process images. The earliest convolutional neural networks are mainly composed of convolutional layers, activation layers, pooling layers, and fully connected layers.

[0077] Due to the performance limitation of the monitoring device in the present invention, the station change monitoring unit based on intelligent recognition is preferably equipped with a lightweight deep learning network.

[0078] First, in terms of model construction, the present invention mainly adopts two solutions to reduce the amount of calculation and parameters of the model. The first is to replace the convolution structure commonly used in deep learning convolutional neural network models with deep separable convolution; second, after weighing the reasoning speed and accuracy, a model with smaller depth and width is adopted. This greatly reduces the number of parameters and calculations of the model and reduces the performance consumption of the monitoring equipment chip. Regarding the first point, deep separable convolution is a variant of the convolution layer, one of the basic units of neural networks. Unlike the original convolution layer, deep separable convolution is mainly divided into two processes, namely channel-by-channel convolution and point-by-point convolution.

[0079] In channel-by-channel convolution, one convolution kernel is responsible for one channel, and one channel is convolved by only one convolution kernel. The number of channels of the feature map generated by this process is exactly the same as the number of channels of the input. For example, for a 5×5 pixel, three-channel color input image, the channel-by-channel convolution first undergoes the first convolution operation. The number of convolution kernels used is the same as the number of channels in the previous layer (channels and convolution kernels correspond one to one). After calculation, a three-channel image is calculated to generate three feature maps. The number of feature maps after the channel-by-channel convolution is completed is the same as the number of channels in the input layer, and the feature map cannot be expanded. Moreover, this operation performs convolution operations on each channel of the input layer independently, and does not effectively utilize the feature information of different channels at the same spatial position. Therefore, point-by-point convolution is required to combine these feature maps to generate new feature maps. Please refer to Figure 4 .

[0080] Point-by-point convolution is very similar to conventional convolution. Its convolution kernel size is 1×1×M, where M is the number of channels in the previous layer. Therefore, the convolution operation here will perform a weighted combination of the feature map of the previous step in the depth direction to generate a new feature map. There are several output feature maps for several convolution kernels. Point-by-point convolution can change the dimension of the channel, so that the features obtained by each convolution kernel can be interactively fused. Please refer to Figure 5 .

[0081] For the second point, the present invention makes comprehensive adjustments to the network depth, network width, and input image resolution of the model with reference to the EfficientNet algorithm to obtain the optimal network parameters for specific needs, so that the network has the dual advantages of network size and recognition accuracy. Please refer to Figure 6 .

[0082] Secondly, prune the organized model to trim redundant or unimportant network structures and parameters. The pruned model can accelerate reasoning, compress storage space and prevent overfitting to a certain extent. Please refer to Figure 7 .

[0083] Again, the present invention further reconstructs the model structure, including merging conv+batchnorm+relu into CBR layer, merging the same tensors in the same layer, and eliminating the concat layer. Please refer to Figure 8 .

[0084] Finally, this scientific and technological project quantizes the processed model. The original model parameters are fp32, and the present invention project quantizes them to int8, which greatly improves the inference speed of the model on the monitoring equipment chip while slightly reducing the accuracy.

[0085] For edge devices, it is known that the storage and memory of the devices themselves are not that large, and model quantization can bring less storage overhead and bandwidth requirements, faster computing speed, lower energy consumption and occupied area. When deployed at the edge, the model can infer images in real time with extremely low energy consumption, thus meeting customer needs.

[0086] Further, participation Figure 2 After receiving the data, the panoramic monitoring unit builds the analysis model algorithm in turn, and performs panoramic monitoring of the entire power system of the monitoring host, including:

[0087] An internal state monitoring model is established based on the obtained voltage parameters, thermal state and vibration conditions to obtain the internal state value;

[0088] An external state monitoring model is established based on the acquired sound signals and circumferential image information to obtain the external state value;

[0089] The panoramic monitoring unit establishes a comprehensive state model according to the internal state value and the external state value, and outputs the comprehensive state value.

[0090] Furthermore, the internal state monitoring model is specifically:

[0091]

[0092] Among them, δ is the internal state value; α1 is the voltage value of the first reference point in the voltage output curve of the total port voltage within the rated time, V; α n is the voltage value of the nth reference point in the voltage output curve of the total voltage port within the rated time, V; n is the number of reference points; T max is the highest temperature that the temperature monitoring module can monitor within the rated time, °C; γ max is the maximum amplitude that the vibration monitoring module can monitor within the rated time, mm; 1.204 and 1.39 are both adjustment constants.

[0093] It should be noted that the rated time can be selected as 12h, which does not affect the operation of the overall model. A reference point is selected at equal intervals.

[0094] Furthermore, the external state monitoring model is specifically:

[0095] η=S max 1.476 ·L 3.58 ·P 0.81

[0096] Where η is the external state value; S max is the maximum sound signal that the sound monitoring module can monitor, db; L is the number of foreign objects monitored by the image monitoring module at the current judgment time, pieces; P is the size of the foreign object monitored by the image monitoring module at the current judgment time, m 3 ; 1.476, 3.58 and 0.81 are adjustment constants.

[0097] Furthermore, the comprehensive state model is specifically:

[0098] μ=δ 1.71 ·η 1.09

[0099] Among them, μ is the comprehensive state value; δ is the internal state value; η is the external state value; 1.71 and 1.09 are adjustment constants.

[0100] Specifically, the panoramic monitoring unit synchronously determines whether the state is abnormal by comparing the comprehensive state value with the set abnormal threshold. When the comprehensive state value is higher than the abnormal threshold, it is determined that the state is abnormal, and the signal triggers the alarm unit to send an alarm signal.

[0101] Specifically, the abnormal threshold is 3.92 or 3.921 or 3.922.

[0102] In addition, in order to simplify the plan, save computing power and cost, when the voltage parameters obtained meet the following model:

[0103]

[0104] Then, the internal state monitoring model is simplified as follows:

[0105] δ = α1·3.77 or 3.771

[0106] Then, the comprehensive state model is simplified as:

[0107] μ=δ·η 1.09

[0108] Among them, δ is the internal state value; α1 is the voltage value of the first reference point in the voltage output curve of the total port within the rated time; α n is the voltage value of the nth reference point in the voltage total port voltage output curve within the rated time; n is the number of reference points; μ is the comprehensive state value; δ is the internal state value; η is the external state value; 1.09 is the adjustment constant.

[0109] Furthermore, the abnormal threshold is specifically 3.80.
