RFID Positioning
RFID Positioning
(OP)
I am looking for a way to position trucks under loadout spouts without guidance from the control room.
Each truck can have different loading location along its length relative to the ends of the truck, as well as a different height.
I am looking for a RFID system/sensor that can do linear positioning at a distance of about 10' and either give me analog or discrete outputs for position. There are few enough trucks moving through that I should be able to put a RFID tag on each truck without an issue. My goal would be to put in a simple stoplight for the drivers to be able to position themselves.
Does anyone know of a sensor?
Thanks,
Joel

If those are not insurmountable issues in your case, it should work fine.

RE: RFID Positioning
I think I can get the haulers to install the tags and maintain them since it is in their best interest to load quickly. Since we have a pretty limited group of haulers I can probably get it on each truck also.
I can not seem to find any active tags that have enough distance (10' ish) in them. Do you know of a manufacturer?
I can do it with laser transmitters and plc logic due to the opening in the truck being so small (about 1.5' dia hole), but i don't think the system will be as robust due to the dust in the environment and the reliance on multiple analog signals.
Thanks.

Siemens Moby U series active tags.
The RF600 Series can go up to 30m, but they are very large and even more expensive.
