Appliance and White Goods Testing

From NIWeek 2012, two National Instruments interns demonstrate testing of a mini-fridge using NI CompactDAQ. As systems become more complicated and change at a faster pace, engineers and scientists need to build more complex measurement systems in less time. Using modular hardware and flexible software architectures ensures that no matter the measurement challenge, the instrumentation can adapt to meet that need.

00:00:00 hi everyone I'm Sam burans I'm an EOP intern here at ni and we're currently here at ni week 2012 and we are in the automated test and uh data acquisition Pavilion we've got the coolest fridge at ni week right here and uh here's rvy to introduce a little bit about the fridge so I'm Ry haar I go to Georgia Tech I'm also an ELP intern and I'm going to be doing the hardware side of this really

00:00:26 cool fridge right here basically when we got this fridge beginning of the summer it looked really bad uh some old Hardware on it and didn't do much we uh put a new eth eanet uh for slot chassis in we put um accelerometer on the fan we have a bunch of measurements for the um current voltage um accelerometer and we added a bunch of blue LEDs cuz that's all you really need on a mini fridge and

00:00:47 Sam's going to talk a bit more about the interface all right so we have a bunch of thermal coues in there so what so we've got eight thermal coues on the inside and we created this 3D model of the fridge on the inside here you can see as I'm awesome spinning it around and uh what we show is the cold and hot spots of the fridge which is important for appliance testing and uh not only

00:01:10 that but we're also monitoring the voltage the current input and uh we're also taking the uh fft uh the vibrations of the fan which uh allows us to get the fan speed it's also pretty cool and this allows us to show the power of deck and how we can take multiple sensors turn them into usable inputs and we can monitor the fridge and uh simultaneously so uh thank you very much and uh we

00:01:37 appreciate uh your time
