Smart Multisensor Node for Remote Elevator Condition Monitoring

The design and implementation of an intelligent multi-sensor module for remote monitoring of the status of elevators are presented herein. The sensor module is an autonomous device that allows the existing lift systems to be efficiently modernized in terms of monitoring their status. The sensor unit monitors the position of the elevator using an inertial navigation system in combination with a barometric altimeter. The evaluation of the performance of the lift system and its technical condition is performed by calculating the basic parameters of the quality of movement, defined by the ISO 187381 standard. The vibration spectrum, the vibration spectrum relative to the position, sound pressure, and lighting levels in the elevator cabin are calculated.
