The future scenarios being worked on at SYS TEC electronic go even further. Klaus Rupprecht describes miniature systems based on smart intelligent sensors - for example in the area of predictive maintenance. It is conceivable to use noise analysis systems that can be attached to the bearing shells of machine tools, for example.
In addition to the usual parameters such as temperature, pressure and humidity, the sensors also monitor the status of the machine. Tiny structure-borne sound microphones are integrated into the beacons for this purpose. "When such a bearing shell in a machine reaches the end of its life, the beacons will hear that," explains Klaus Rupprecht. Because when the balls in a ball bearing or the rollers in a roller bearing run, the surfaces wear out. The further the wear progresses, the more the background noise changes. This means that the sensor records different noise signatures, depending on the bearing condition.
Frequency analysis can detect the connected systems when the end of life is approaching and inform the maintenance department, which can then prepare for the exchange with time and spare parts.
In the near future there are plans to integrate lighting into the tracking systems. Data transmissions coded in light to beacons and machines would be conceivable.
