Labview System in Car for Multiple Days

Solved!
Go to solution

Hello All,

 

We are attempting to have a DAQ run in a trailer measuring displacement and loads for three multiple days.

 

In our previous testing we used seven NI 9236 strain modules and one NI 9205 analog input module, which are plugged into a CampactDAQ ethernet chassis. This chassis is then plugged into a laptop that runs our software. This was all done indoors, where we could use a standard wall plug for power supply.

 

I was wondering if there was anyway that we could make this same system run for 3 straight days, where half of the day the DAQ will be powered by the truck power supply, but during nights, the system would have to run off of a 10VDC power supply or similar power supply.

 

Does anybody have any ideas of how to power the system or any external power supplies that would be able to last three days while the system is running?

 

Thanks!
