Project:
����������� The ME department has a test dummy
that is equipped with a variety of sensors such as load cells and
accelerometers.� This dummy is going to
be sent through avalanches to determine the forces that would affect a real
human.� Currently the sensors interface
with a PC running LabView.� A dedicated
data acquisition system needs to be implemented so that the dummy can be sent
down in an avalanche and have information from the sensors recorded.�
Requirements:
The data acquisition system needs to be small enough to fit
in the dummy or in a small backpack.� The
dummy will sit overnight on a snowy mountain so consideration for the cold
needs to be taken into account.� The data
acquisition system needs to be able to interface with the current sensor bank
and record large amounts of data.
Update: 11/01/2007
����������� Several sub-systems of the project
are operational.� The analog-to-digital
conversion and Compact Flash memory have been proven.� Before designing a PCB for the data logger,
tests must be run using a breadboard to verify component operation.� Adapters must be made so that small PCB
centric parts can be used with a larger breadboard.� Here are the current adapter board designs
that are currently being used on the project.
