Abstract: A method in which vibrations of a vibration machine, more particularly of a vibrating screen and a vibratory conveyor, are measured by a vibration sensor during operation. The vibration sensor measures vibration components of the vibrations of the vibration machine in three spatial directions of a Cartesian sensor coordinate system. The three vibration components form a vibration vector. In the vibration measurement processes, a gravity vector describing the direction of gravity is determined. Furthermore, a machine vector describing a preferred direction of a forced vibration of the vibration machine is determined. In addition, a three-dimensional Cartesian measurement coordinate system is formed, which is oriented on the basis of the direction of gravity and the preferred direction. The vibration vector is mapped from the sensor coordinate system to the measurement coordinate system.

Abstract: A method for recognizing a rail vehicle wheel as well as an arrangement for recognizing a rail vehicle wheel. A specific detection pattern of the rail vehicle wheel to be identified is ascertained using rollover signal of a rail vehicle wheel to be identified, which is ascertained with the aid of a load measuring device arranged on a rail, the rollover signal describing a time characteristic of a rail load induced by the rail vehicle wheel to be identified on the rail equipped with the load measuring device during the rollover, and the specific detection pattern comprising one or multiple identification parameter(s)/characteristic value(s) ascertained using the rollover signal. The ascertained specific detection pattern of the rail vehicle wheel to be identified is compared with one or multiple predefined reference-specific detection pattern(s) of rail vehicle wheels, and the rail vehicle wheel to be identified is identified by the comparison.

Abstract: A method, apparatus and computer program are provided for monitoring operation of a machine having a mechanical component. the method involves receiving sensor data comprising a time series of measurements of an operational parameter of the machine corresponding to a state variable and processing the time series of measurements for the state variable using a machine-learning model pre-trained to predict normal operational behaviour of the machine based on values of the state variable observed for a time period during normal operation of the machine. The standardized residual for the state variable is calculated across the time series based on a prediction of the pre-trained machine-learning model and any deviation from normal operation of the machine is identified based on values of the standardized residual.
