[labnetwork] Interlock Boxes

Sat Jul 12 11:34:27 EDT 2014

Hi Shiva,

There are a lot of things you need do in order for the PhpScheduler to work with the door controls. Ideally, you need

(1)    write program to interface with the RFID card readers. Each reader must have its own ID if you have multiple doors and each door has in/out readers.

(2)    integrate the PhpScheduler with your university single sign-on. Each RFID card must be tied with the university SSO ID, so that you can chain up card swipe – SSO ID – user validation in scheduler program. Each university SSO may have different mechanism, such as AD, Shibboleth, CAS, or SAML.

(3)    Interface with interlock that in turn controls the door lock. As John mentioned you need not design your own interlock because we have a bunch of commercially available products you can use.

At Northwestern University, we use HID card readers, and I have done all these items with Java. Not sure if PHP has similar capability in lower level hardware controls.

For tailgating, we implemented a monitoring system to display all the “current” users who are working in the lab. A user’s name is shown up as soon as the ID card is swiped. This monitoring works well – managers can easily spot a person who is working in the lab but the name is not shown on the big display.

Hope this helps,
Shuyou

Hello All,

I am trying to set a interlock system for our cleanroom. In the process I was able to get the phpscheduler up running. Before I design or buy the interlock I need your inputs regarding how to set up.

Do the user log in to computer that is attached to the unit and validate the credentials and then use the equipment. Inorder to do that user data should be validated by the scheduler system, in that case does user have separate id created or it will be same associated with the campus ID.

Do the user use separate swipe card in the interlock to access the system.

Apart from the user access, currently the users access the cleanroom with swipe in card and when they leave they swipe out. But not all the users swipe in or swipe out. Our door system is designed in such a way that it will be opened for atleast for 10-20sec , but with this there is possibility of other users following the previous user without swiping the card. Does any one have system that detect the user based on proximity that automatically gets the user information based on RF ID card without swipe in.

--Thanks

We use ethernet relay boards from National Control Devices<http://www.controlanything.com/Relay/Relay/ETHERNET_PROXR>, controlled by Badger (the new version of Coral). NCD also makes wifi connected relays. Having two relays on a board makes it easy to keep isolated grounds isolated. Each board requires its own static IPv4 address. The boards can be easily mounted in a 6"x6" electrical box, or in the custom-fitted plastic case from Badgerlms.<http://badgerlms.com/> I suggest you keep these boards behind a firewall, since they run a tiny operating system and web page, but with only minimal security.

Hi All,

EPFL is using Ether IO24 R from http://www.elexol.com/IO_Modules/

Our software is homemade but we have a call for tenders running in order to “couple our homemade software” with a commercial package.

We will keep you posted on this important move on which we are investing a lot of effort.

With my very best regards,

Kolin:

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.

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.

I don't have experience with either Cores or iLab software to know what, if any, interlocking hardware has been interfaced with their systems.

Good luck,

John

Hi!  Here at WVU, we are going to interlock our tools to our reservation software.  Everyone at the UGIM was talking about the “blue boxes” from Advantech.  Can anyone provide me with a model number?  Also, has anyone interfaced these boxes with Cores or iLabs software?
