Let me take a crack at answering some of your questions.<br>
<br>
First, I doubt that you need to design an interlock ... there a
plenty of options to just by them.<br>
<br>
Most systems with which I am familiar (but not all ...)
allow/require you to enable an interlock on a piece of equipment
from the same system on which reservations are made. Most of those
systems are logged into with an old fashioned user name and
password. But there are lots of variations: Gary Spinner may
correct me, but, as I recall, Georgia Tech has a card reader on each
piece of equipment that reads the university ID card and turns on
the equipment if the person is authorized to use that tool. Thee
are probably other card-reader per tool installations as well.<br>
<br>
Whether you use lab-specific or campus-wide ID for authentication
likely depends on your campus infrastructure. A number of campuses
have and use central authentication using LDAP or Kerberos with the
campus ID. Even with that, however, you still likely need to get
information from your in-lab system to determine equipment
qualifications, special privileges, etc. Of course, for that to
work, the in-lab name/ID has to match the campus-wide name/ID.<br>
<br>
The problem of "tailgating" (3 or 4 people entering on a single card
swipe) is a common problem for most access systems. I have no
direct experience with the long-range RFID units that should, in
principle, read a card as you walk though the door and should
greatly reduce that problem.<br>
<br>
Good luck,<br>
<br>

I believe that most folks are using the Advantech ADAM-6060
or ADAM-6066 6-channel IP-addressable relay modules for
interlocking. Others use modules that come from National
Control Devices that have 1-, 2-, 4-, and 8-relay devices
with current ratings from 5 to 30 amps. Most folks are
currently using hard-wired ethernet connections, but some
wireless options are also available.
<br>
<br>
I believe that most of these IP-addressable relays are
functionally equivalent but would certainly have minor
differences in the default port that is used and the exact
command sent to turn on, turn off, or check the status of a
given relay channel.<br>
<br>
I don't have experience with either Cores or iLab software
to know what, if any, interlocking hardware has been
interfaced with their systems.<br>
<br>
Good luck,<br>
