[0049] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0050] The superconducting tape temperature monitoring method and device provided in this application are applied to electronic equipment for monitoring the temperature of superconducting tape in a superconducting magnet to determine whether the superconducting tape's operating temperature is abnormal. The electronic equipment can be understood as a computer, server, cloud platform, or even an embedded device with data computing and information processing capabilities, and the temperature monitoring device can be understood as the electronic equipment itself or a functional module of the electronic equipment. Based on the above premise, this application provides the following specific embodiments.
[0051] FIG1 is a flow chart of a method for monitoring the temperature of a superconducting tape according to an embodiment of the present application.
[0052] As shown in FIG1 , the temperature monitoring method provided in this embodiment is used to monitor the temperature of a superconducting tape of a superconducting magnet. The temperature monitoring method comprises the following steps:
[0053] S101. Acquire multiple operating parameters of a superconducting magnet and a real-time temperature value of a superconducting tape.
[0054] The multiple operating parameters include the vacuum level within the superconducting magnet cavity and the temperature between the cold head and the connecting block, which are key components of the superconducting magnet. They also include the voltage and magnetic field strength of the superconducting tape. These operating parameters and real-time temperature values are detected by sensors located in corresponding locations within the superconducting magnet.
[0055] S103: Input multiple operating parameters into the temperature prediction model for calculation.
[0056] This temperature prediction model extracts a trained neural network model. When implementing the present invention, the temperature prediction model calculates these operating parameters based on the aforementioned operating parameters to obtain a predicted temperature value for the superconducting tape. This predicted temperature value refers to the ideal operating temperature of the superconducting tape under the operating conditions determined by the aforementioned operating parameters. This serves as a benchmark for comparing the operating temperature of the superconducting tape. Theoretically, the closer the actual temperature of the superconducting tape is to the predicted temperature value, the more normal its operating conditions are.
[0057] S105: Determine whether the operating temperature is normal based on the predicted temperature value and the real-time temperature value.
[0058] After obtaining the ideal operating temperature of the superconducting tape, i.e., the predicted temperature value, the predicted temperature value is compared with the real-time temperature value to determine whether the operating temperature of the superconducting tape is normal. This is specifically implemented by the following means:
[0059] First, the difference between the predicted temperature value and the real-time temperature value is calculated to obtain the temperature residual between the two.
[0060] Then, a determination is made as to whether the temperature residual is within a preset residual threshold range [-3σ, 3σ]. If so, the operating temperature of the superconducting tape is determined to be normal; if not, the operating temperature is determined to be abnormal. The preset residual threshold range can be obtained from a temperature prediction model.
[0061] As can be seen from the above technical solution, this embodiment provides a method for monitoring the temperature of a superconducting tape. This method, applied to electronic equipment, is used to monitor whether the operating temperature of a superconducting tape in a superconducting magnet is abnormal. Specifically, the method comprises obtaining multiple operating parameters collected from the superconducting magnet and the real-time temperature of the superconducting tape; inputting these multiple operating parameters into a pre-trained temperature prediction model to calculate a predicted temperature value for the superconducting tape; and determining whether the operating temperature is abnormal based on the degree of match between the predicted temperature value and the real-time temperature value. This solution can determine whether the operating temperature of the superconducting tape is normal, enabling the system or maintenance personnel to take timely remedial measures when an abnormality occurs.
[0062] In addition, the temperature monitoring method provided in this embodiment also includes the following steps, as shown in FIG2 .
[0063] S102: Preprocess multiple working parameters.
[0064] Specifically, the multiple working parameters acquired are processed for deduplication, outlier removal, and interpolation. Deduplication refers to the sensor collecting multiple or multiple data points at a certain rate, and averaging multiple data points per second. Outlier removal involves interpolating the five numbers before and after a particular data point (if there are fewer than five, as many as possible are used). If the error between the interpolated data and the collected data exceeds a reasonable range, the collected data is considered an outlier and replaced with the interpolated data. Interpolation is used to supplement missing data. If a sensor does not collect data in a certain second, the data is supplemented by interpolating the five data points before and after that second (if there are fewer than five, as many as possible are used).
[0065] In addition, this embodiment further includes the following steps, as shown in FIG3 , which are used to train the temperature prediction model required for the above-mentioned temperature prediction.
[0066] S301. Obtain historical data of superconducting magnets and construct a training sample set.
[0067] Specifically, a training sample set is constructed by acquiring historical data from the superconducting magnet. This data includes multiple historical operating parameters and historical real-time temperature values of the superconducting tape. These parameters include the vacuum level within the superconducting magnet cavity, the temperature between the cold head and the connection block, and the voltage and magnetic field strength of the superconducting tape. After obtaining this historical data, it can optionally be preprocessed. This preprocessing is similar to the preprocessing of operating parameters described above and will not be detailed here.
[0068] S302: Perform model training based on the training sample set.
[0069] This application is to input the training sample set into the long short-term memory neural network for model training, thereby obtaining the temperature prediction model. This application uses Keras to build the long short-term memory neural network. For the long short-term memory neural network, a layer of LSTM is set as the hidden layer to accept input, a layer of DENSE is used for output, the loss function uses mean square error, and the optimization algorithm uses Adam. At the same time, in order to prevent overfitting, the Dropout layer is used with a parameter set to 0.2 to enhance the generalization of the model. For the hyperparameters involved, the number of hidden layer neurons is 24, the learning rate is 0.01, the batch size batch_size is 128, and the number of iterations is 100.
[0070] The temperature prediction model can be obtained by the above scheme. In addition, the following steps can also be included, as shown in Figure 4:
[0071] S303: Calculate historical predicted temperature values based on the temperature prediction model.
[0072] That is, the trained temperature prediction model is used to process multiple historical working parameters to obtain historical predicted temperature values.
[0073] S304: Calculate a preset residual threshold range based on the historical predicted temperature value and the historical real-time temperature value.
[0074] That is, calculate the residual between the historical predicted temperature value and the corresponding historical real-time temperature value, and determine the residual threshold range based on the 3σ criterion. The calculation formula of σ is as follows:
[0075] where r i is the residual, and n is the number of samples in the training set. The probability that the value is distributed in [-σ, σ] is 0.6826, the probability that the value is distributed in [-2σ, 2σ] is 0.9544, and the probability that the value is distributed in [-3σ, 3σ] is 0.9974. We can see that the probability that the residual is not in [-3σ, 3σ] is less than 0.3%.

[0080] FIG5 is a block diagram of a temperature monitoring process for a superconducting tape according to an embodiment of the present application.
[0081] As shown in FIG5 , the temperature monitoring device provided in this embodiment is used to monitor the temperature of a superconducting tape of a superconducting magnet. The temperature monitoring device includes a parameter acquisition module 10 , a first calculation module 30 , and a state judgment module 50 .
[0082] The parameter acquisition module is used to obtain multiple operating parameters of the superconducting magnet and the real-time temperature value of the superconducting tape.
[0083] The multiple operating parameters include the vacuum level within the superconducting magnet cavity and the temperature between the cold head and the connecting block, which are key components of the superconducting magnet. They also include the voltage and magnetic field strength of the superconducting tape. These multiple operating parameters and real-time temperature values are detected by sensors installed in corresponding locations of the superconducting magnet.
[0084] The first calculation module is used to input multiple operating parameters into the temperature prediction model for calculation.
[0085] This temperature prediction model extracts a trained neural network model. When implementing the present invention, the temperature prediction model calculates these operating parameters based on the aforementioned operating parameters to obtain a predicted temperature value for the superconducting tape. This predicted temperature value refers to the ideal operating temperature of the superconducting tape under the operating conditions determined by the aforementioned operating parameters. This serves as a benchmark for comparing the operating temperature of the superconducting tape. Theoretically, the closer the actual temperature of the superconducting tape is to the predicted temperature value, the more normal its operating conditions are.
[0086] The status judgment module is used to judge whether the operating temperature is normal based on the predicted temperature value and the real-time temperature value.
[0087] After obtaining the ideal operating temperature of the superconducting tape, i.e., the predicted temperature value, the predicted temperature value is compared with the real-time temperature value to determine whether the operating temperature of the superconducting tape is normal. This is specifically implemented by the following means:
[0088] First, the difference between the predicted temperature value and the real-time temperature value is calculated to obtain the temperature residual between the two.
[0089] Then, a determination is made as to whether the temperature residual is within a preset residual threshold range [-3σ, 3σ]. If so, the operating temperature of the superconducting tape is determined to be normal; if not, the operating temperature is determined to be abnormal. The preset residual threshold range can be obtained from a temperature prediction model.
[0090] As can be seen from the above technical solution, this embodiment provides a superconducting tape temperature monitoring device, applicable to electronic equipment, for monitoring whether the operating temperature of a superconducting tape in a superconducting magnet is abnormal. Specifically, the device obtains multiple operating parameters collected from the superconducting magnet and the real-time temperature of the superconducting tape; inputs these operating parameters into a pre-trained temperature prediction model to calculate a predicted temperature value for the superconducting tape; and determines whether the operating temperature is abnormal based on the degree of match between the predicted temperature value and the real-time temperature value. This solution can determine whether the operating temperature of the superconducting tape is normal, allowing the system or maintenance personnel to take timely remedial measures when an abnormality occurs.
[0091] In addition, the temperature monitoring device provided in this embodiment further includes a pre-processing module 20 , as shown in FIG6 .
[0092] The preprocessing module is used to preprocess multiple working parameters.
[0093] Specifically, the multiple working parameters acquired are processed for deduplication, outlier removal, and interpolation. Deduplication refers to the sensor collecting multiple or multiple data points at a certain rate, and averaging multiple data points per second. Outlier removal involves interpolating the five numbers before and after a particular data point (if there are fewer than five, as many as possible are used). If the error between the interpolated data and the collected data exceeds a reasonable range, the collected data is considered an outlier and replaced with the interpolated data. Interpolation is used to supplement missing data. If a sensor does not collect data in a certain second, the data is supplemented by interpolating the five data points before and after that second (if there are fewer than five, as many as possible are used).
[0094] In addition, this embodiment further includes a sample set construction module 31 and a model training module 32, as shown in FIG7 , for training the temperature prediction model required for the above-mentioned temperature prediction.
[0095] The sample set construction module is used to obtain historical data of superconducting magnets and construct a training sample set.
[0096] Specifically, a training sample set is constructed by acquiring historical data from the superconducting magnet. This data includes multiple historical operating parameters and historical real-time temperature values of the superconducting tape. These parameters include the vacuum level within the superconducting magnet cavity, the temperature between the cold head and the connection block, and the voltage and magnetic field strength of the superconducting tape. After obtaining this historical data, it can optionally be preprocessed. This preprocessing is similar to the preprocessing of operating parameters described above and will not be detailed here.
[0097] The model training module is used to train the model based on the training sample set.
[0098] This application is to input the training sample set into the long short-term memory neural network for model training, thereby obtaining the temperature prediction model. This application uses Keras to build the long short-term memory neural network.

[0100] The prediction processing module is used to calculate historical predicted temperature values based on the temperature prediction model.
[0101] That is, the trained temperature prediction model is used to process multiple historical working parameters to obtain historical predicted temperature values.
[0102] The second calculation module is used to calculate a preset residual threshold range based on the historical predicted temperature value and the historical real-time temperature value.
[0103] That is, calculate the residual between the historical predicted temperature value and the corresponding historical real-time temperature value, and determine the residual threshold range based on the 3σ criterion. The calculation formula of σ is as follows:
[0104] where r i is the residual, and n is the number of samples in the training set. The probability that the value is distributed in [-σ, σ] is 0.6826, the probability that the value is distributed in [-2σ, 2σ] is 0.9544, and the probability that the value is distributed in [-3σ, 3σ] is 0.9974. We can see that the probability that the residual is not in [-3σ, 3σ] is less than 0.3%.
