At Electronica 2018, STMicroelectronics and Lenord + Bauer are jointly presenting Artificial Intelligence (AI) in industrial sensor systems, with a use case for vibration analysis in trains.

The intelligent sensor used by Lenord + Bauer is based on an accelerometer and STM32 microcontroller from ST packaged in a form factor evaluation board (STEVAL-BFA001V1B). The sensor is designed to be attached to a train wheel bogie (wheel carriage) and has embedded AI to detect damage or material fatigue at an early stage. The Neural Networks embedded in the microcontroller have been trained with pre-processed data acquired from the integrated sensor on a test bench and converted into optimized code for the STM32 microcontroller thanks to a highly-efficient tool – the STM32Cube.AI. This software tool, which is part of the STM32 SW ecosystem, allows fast automatic conversion of pre-trained Neural Networks into optimized libraries that can run on any STM32 MCU.

Lenord + Bauer is an internationally active specialist for motion sensors and integrated drive technology. The company develops, produces and distributes solutions for the transport industry, with a focus on railways, and motion automation, particularly tools and packaging machine applications.
