The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein.

For easy understanding, the following describes a specific flow of an embodiment of the present invention, referring to fig. 1, and one embodiment of a method for detecting an isolating switch based on deep learning in the embodiment of the present invention includes:
s101, performing multidimensional data acquisition on the running state of a target isolating switch through a preset sensor group to obtain initial multidimensional sensing signal data;
it can be appreciated that the execution subject of the present invention may be a deep learning based disconnecting switch detection device, and may also be a terminal or a system, which is not limited herein. The embodiment of the invention is described by taking a server as an execution main body as an example.
Specifically, a suitable set of sensors is selected. The sensor is capable of monitoring a multi-dimensional signal, such as current, pressure, temperature, etc., associated with the operating state of the disconnector. Different sensors require different operating principles and techniques and therefore the sensor type needs to be selected according to specific requirements. For example, a current sensor may be used to monitor current data, a pressure sensor to monitor pressure data, a temperature sensor to monitor temperature data, etc. The position where the sensor is installed should be able to accurately reflect the state of the disconnector. For example, in terms of current monitoring, sensors may be mounted on the cable connection points or the switchgear to ensure that current changes are accurately captured. Pressure sensors may be installed on the gas or liquid lines to monitor pressure changes. Temperature sensors may be mounted at critical locations to measure temperature data in real time. The sensor will continuously collect multidimensional signal data including current, pressure, temperature, etc. These data will be transmitted to the data acquisition system in the form of digital or analog signals. The data acquisition system stores the data in a database or cloud platform for later processing and analysis. In the data acquisition process, accuracy and continuity of data need to be ensured. Calibration and maintenance of the sensor is necessary to ensure proper operation. In addition, the data acquisition system should have fault detection and alarm functions, as well as data redundancy mechanisms to avoid data loss.
S102, performing modal decomposition on initial multidimensional sensing signal data to obtain a plurality of intrinsic modal component data, and respectively performing feature extraction and feature classification on the plurality of intrinsic modal component data through a preset multiscale entropy algorithm to obtain noise aliasing component data;
specifically, the system performs modal decomposition. The multi-dimensional sensing signal data is decomposed into eigenmode component data. The system uses a collective empirical mode decomposition analysis algorithm. This algorithm is a mathematical method that can decompose the signal into eigenmodes of different frequencies. Parameter settings are critical to the performance of the algorithm. The system selects appropriate parameters to ensure accuracy and effectiveness of the modal decomposition. For example, the system sets algorithm parameters such as sampling frequency and decomposition scale. And then, according to the set parameters, carrying out modal decomposition on the initial multidimensional sensing signal data by the system to obtain a plurality of intrinsic modal component data. These component data represent the vibrational modes of the signal at different frequencies. The system analyzes these eigenmode component data using multi-scale entropy. Multiscale entropy is a feature analysis method that can be used to measure the complexity and randomness of signals. The system applies a multi-scale entropy algorithm to each eigenmode component data to obtain multi-scale entropy value features. The multi-scale entropy value features reflect the information entropy of the signal at different time scales. With these features, the system better understands the complexity and randomness of the signal. In the feature extraction process, each intrinsic mode component data will obtain a corresponding multi-scale entropy feature. The system uses a support vector machine model to perform feature classification to obtain noise aliasing component data. The support vector machine is a machine learning algorithm that can be used to classify problems. The system takes as input multi-scale entropy features, and the support vector machine model will classify each eigenmode component data as noise aliased component data or non-noise aliased component data according to these features. For example, assume that the system is monitoring an isolation switch in a power system, and a current signal is collected by a current sensor. The system uses an aggregate empirical mode decomposition analysis algorithm to perform mode decomposition on the current signal to obtain intrinsic mode component data of different frequencies. The system applies a multi-scale entropy algorithm to each eigenmode component data to calculate a multi-scale entropy value characteristic. These features will reflect the entropy of the current signal at different time scales. The system inputs the multi-scale entropy characteristics into a support vector machine model for classification. The model will classify each eigenmode component data and determine if they are noise aliased component data. This helps the system identify and isolate the noise aliasing components to better understand the operating state and detection performance of the disconnector. By this feature, the system analyses the sensed signal of the disconnector deeper, extracts features, classifies noise aliasing components, and thereby provides more accurate data and information for operational state detection and life prediction.
S103, performing signal filtering processing on the initial multi-dimensional sensing signal data according to the noise aliasing component data through a preset back propagation neural network and a Kalman filter to obtain standard multi-dimensional sensing signal data;
it should be noted that the system constructs and trains the back propagation neural network. The purpose of this neural network is to predict from the noise aliasing component data, thereby helping to filter out noise aliasing. The noise aliasing component data is taken as input data, and the initial multidimensional sensing signal data is taken as target output of the neural network. In this way, the neural network will learn how to recover the original signal from the noise aliasing component data. The structure of the back propagation neural network is designed to comprise an input layer, a hidden layer and an output layer. An appropriate neural network architecture is selected to achieve data reduction. The back propagation neural network is trained using existing data sets. The weight and the bias parameters of the neural network are continuously adjusted through a back propagation algorithm, so that the neural network can accurately restore multidimensional sensing signal data. Subsequently, another independent data set is used to verify the performance of the neural network, ensuring that it accurately restores the multi-dimensional sensor signal data. Once the system training is completed, the system uses it to predict new noise aliasing component data. The neural network will generate new estimated data from the input noise aliasing component data. The system inputs the new estimated data into a preset kalman filter to perform signal filtering processing. The kalman filter is a recursive filter for estimating the state of the system and filtering out noise. The kalman filter requires an initial state estimate, which may be new noise aliasing component data generated by a neural network. Subsequently, an observation model and a state transition model of the kalman filter are defined to describe the dynamic variation of the signal and the measurement noise. The new estimation data is combined with the observation model and the state transition model using a kalman filter algorithm to estimate the state of the system. This process will filter out noise resulting in standard multidimensional sensing signal data.
S104, carrying out sensing data conversion and classification on the standard multidimensional sensing signal data to obtain target current data, target pressure data and target temperature data;
specifically, the standard multidimensional sensing signal data is converted into target multidimensional attribute data. Important features are extracted from the raw signal to better describe the different sensing properties. For example, in a power system, the system extracts frequency components by performing frequency domain analysis on a current signal; performing waveform characteristic analysis on the pressure signal, and extracting the amplitude of pressure change; and carrying out trend analysis on the temperature signal, and extracting the characteristic of temperature rise and fall. The system inputs the obtained target multidimensional attribute data into a preset cluster analysis model. This model will help to divide the data into different clusters, each cluster representing a state or characteristic. At this stage, the system selects an appropriate clustering algorithm, such as K-means clustering, and determines the number of clusters. Cluster analysis helps identify patterns and clusters of different states. The running of the cluster model will produce a cluster center for each cluster. These cluster centers represent the average features of each cluster. For example, for a power system, the initial current cluster center represents the average characteristics of the different current modes, the initial pressure cluster center represents the average characteristics of the different pressure modes, and so on. The system calculates the distance between the target multidimensional attribute data and the initial cluster center. This is typically done using euclidean distance or other distance measures. The data points will be assigned to cluster centers closest to them, thereby determining the clusters to which they belong. The system performs a correction of the cluster center by comparing the distance of the data point from the initial cluster center. This helps to more accurately reflect the distribution of the data, improving the accuracy of clustering. The corrected cluster centers will better represent the average features of the different states or characteristics. And the system performs secondary clustering on the target multidimensional attribute data by using the target current clustering center, the target pressure clustering center and the target temperature clustering center again.
