Thermal Overload protection for controlled device?

Post by mbushroe » February 3rd, 2014, 2:05 pm

We are working on developing software and testing it on prototype hardware. We use several iboot G2+ units to allow remote users to remote desktop to the host computer that has all the serial interfaces and private local network including the iboot. Since the prototype hardware was built from quick to assemble parts and not custom, power efficient parts, the equipment runs hot and needs one or more large external fans to stay within safe limits.

With lots of software and programmers and few prototype boxes, it is desirable to be able to run the units late at night and on weekends to free up more time for those who want to remote from home. However, without some way to monitor the prototype box's temperature, or be certain that a thermal overload system we can't risk running the units when there isn't at least one person physically present in the lab to notice when a fan fails or wasn't started and manually shut down the machine to prevent thermal damage.

My question is has anyone else run into a similar problem? Can the USB port and the DXP protocols be used to monitor the temperature remotely? (I can see that if so, the DXP messages allow for shutting down power until it cools). Are there examples of the code to do this. or tutorials or even a white paper? Is there an off-the-shelf product that can provide the thermal overload protection that be added if the iboot is not able to do this directly?

Thanks for the help.
