This week, our team met up with the vehicle control team to
discuss about the feasibility of the Hall Effect sensors on both positioning
and switching. Both team came up with the idea of using the Hall Effect sensor’s
digital output as the positioning tool and using a second sensor for switching
and detecting the magnets on the track. Originally we would like to keep the
design of the Korean team. However, this idea was rejected by the Track
development and Bogie team because the magnetic detector on the podcar will
contact with the track. And the hold system needs to be redesigned if the
control team wants to keep the magnetic detector. We tested the RFID sensor,
but fail to make it work properly. Our team started searching some of the
smaller Hall Effect sensors. And we are getting an A3144 Hall Effect sensor in
recent days.
The team is also working on searching possible corrugated
metal strip supplier on the market. We are looking for products similar to the
metal strip that we want, and trying to contact the manufacturer of the product
to search for possible assistance.
