Team Vision for Integrated System Build & Test Phase

Test Results Summary



1. Electrical Subsystem: Because of some charring observed in the plywood base during circuit operation, an informal test was performed on the power resistors under operational conditions to gain an estimate on the temperature changes over time. The graphs below show the average temperature increase is 7.4F per second. The charring temperature of wood is 250-300F, and a 10s burn would require a temperature buffer of 80-90F. In order to protect the wood enclosure a temperature cutoff was added to the power line that opens at 250F.

2. DAQ/Control Subsystem: The control portion of this subsystem passed the test criteria. The myDAQ was able to successfully output +5VDC to switch on the transistors which subsequently power the PCU and gas solenoid. The data acquisition portion of the subsystem along with appropriate safety interlocks are next to be implemented. Updated screenshots of the LabVIEW VIs are shown below.
