Abstract: A method for detecting temperature rise inside a superconducting levitation device based on deep learning is provided. An initial vibration acceleration information, an initial temperature rise information, and a vibration acceleration detection information are obtained. Feature extraction is performed on the initial vibration acceleration information to obtain a high-frequency feature parameter set and a low-frequency feature parameter set. Wavelet band energy calculation is performed for the high-frequency feature parameter set and the low-frequency feature parameter set to obtain a wavelet band energy information. The wavelet band energy information and the initial temperature rise information are input into a preset deep learning network for training to obtain an internal temperature rise detection model of the superconducting levitation device. The vibration acceleration detection information is input into the internal temperature rise detection model to obtain an internal temperature rise prediction information to reflect real-time temperature rise of the superconductor.

Abstract: A cryostat device for a superconducting magnetic levitation train includes a conduction assembly, a support assembly and a refrigeration assembly. The conduction assembly includes a conduction shell, a copper box arranged in the conduction shell, and a thermally-conductive support rod assembly. A top of the thermally-conductive support rod assembly is connected with a bottom of the copper box. A bottom of the thermally-conductive support rod assembly is connected with a bottom wall of the conduction shell. A top of the copper box is provided with a superconducting bulk accommodating cavity. The bottom of the copper box is provided with a cooling energy connecting end. A top of the support assembly is configured to support the conduction assembly. A bottom of the support assembly is connected with a bogie chassis. The refrigeration assembly is provided with a cooling energy input end connected with the cooling energy connecting end.
