摘要： A metro rail corrugation measurement method based the Seq2Seq model and vibration and noise data fusion comprises the following steps: Constructing a time series data set corresponding to floor longitudinal acceleration and train speed based on historical data of metro trains; Constructing the metro train mileage matching prediction model based on the Seq2Seq model, training the metro train mileage matching prediction model by time series data sets, and inputting the inside floor longitudinal acceleration of the metro train to be detected into the trained metro train mileage matching prediction model to obtain the running speed of the metro train to be detected. According to the vibration and noise data of the metro train to be detected, the vibration and noise composite index of the rail corrugation is calculated to determine the wavelength and amplitude information corresponding to the rail corrugation.

摘要： A system and method for automating railroad maintenance for a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables the automating of an adaptive maintenance process for the asset that is being maintainanced. The system can identify a railroad asset scheduled for maintenance using various forms of inspection including real-time kinematic (RTK)-corrected GPS data, radar signal processing data, and real-time imaging. The system also provides for the acquisition and upload of asset pictures for verification and analysis of a railroad asset. The system can identify a next location to perform maintenance and can calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics. The system further can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset.

摘要： A data collection device according to an aspect of the present disclosure includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: detect a target data point that is a data point at which a target is observed in acoustic data obtained by observation of the target; determine an analysis range in the acoustic data based on the target data point; detect an abnormality in the analysis range; and output information of the analysis range in which the abnormality is detected.

摘要： A microphone assembly including an outer housing, an inner housing, a printed circuit board (PCB) and a cord. The outer housing includes an outer surface, an inner surface opposite the outer surface and defining an opening there through, and a plurality of attachment structures protruding from the inner surface thereof. The inner housing includes an outer surface, an opening, and a plurality of attachment structures protruding from the outer surface thereof. The PCB includes at least one micro-electromechanical systems (MEMS) microphone including an acoustic port. The PCB is coupled to the inner housing such that the acoustic port of the at least one MEMS microphone is positioned within the opening. The cord interconnects the attachment structures of the outer and inner housings, respectively, together.
