    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 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: An example road sensor apparatus comprises: a sensor casing comprising a first surface for interfacing environmental conditions on a surface of a pavement, a second surface for interfacing a sensor level adjustment element, and a sensor portion including one or more sensor apparatuses; the sensor level adjustment element comprising plastic material that exhibits permanent compression in response to being subjected to a pressure that exceeds a threshold pressure and having a first surface for interfacing the sensor casing and a second surface for interfacing a bottom of a recess in the pavement; and an installation sleeve, the sensor casing and the sensor level adjustment element arranged adjacent to each other and at least the sensor casing arranged within the installation sleeve such that the sensor casing is moveable with respect to the installation sleeve in response to a pressure that exceeds said threshold pressure being applied on its first surface.
