Global Technical Marketing Engineer Dan Rozwood demonstrated his Zynq-based sensor fusion demo at last week’s one-day Avnet X-fest held in San Jose. The demo was inspired by the sort of sensing needed for an industrial plastics extruder. It combines data from at least nine sensor types:
Analog and digital isolated inputs
Remote current sensing
RTD temperature sensor
Ambient pressure transducer
Quad thermocouple sensor
Accelerometer to sense motor movements and bearing health
Voltage monitor and power-consumption sensor
MR (magneto resistive) sensor for monitoring motor movement
Inductive sensor for monitoring motor movement
All of these sensors connect to appropriate interfaces in the Zynq SoC, which provides true parallel processing to ensure the time correlation among the sensor readings. As Rozwood says in the 8-minute video below, sensor fusion is about “putting three things in and getting four out.” By that, he means that the various sensor inputs can be combined to derive other measurements from the sensed parameters.
Here’s the video of this impressive demo:
