SMarble localization in industrial mixing tanks using TDOA and echo data

Samenvatting

Industrial mixing is a field where yearly between 1 billion and 10 billion dollars are lost due to badly mixed batches. The reason for this is that industrial mixing still relies on simplified models that do not take into account the specific conditions within an industrial mixing tank. The main component that contributes to good mixing is turbulence. SMarbles which are small sensor balls can be used to measure this turbulence utilizing the internalIMU. To do this the location of the SMarble has to be linked to a location in the mixing tank. This can be done by using an ultrasonic transducer in the SMarble and hydrophones in the tank. This allows the SMarble location to be determined using time difference of arrival (TDOA). In addition to this echo data is added to be able to determine the height of the SMarble in case the TDOA timings become too similar.
