More About RFID

Thoughts on it's application to agility

                   

  Martin Pollard, father of the electronic timer in the UK, first had a look at Radio Frequency Identification (RFID) while researching the Taryntimer four years ago. Consequently he was very interested in what Tony di Bartolo had to say about it in his article 21st Century Agility. Here are his conclusions.

I searched the Internet for information. The first site I came across was by a man in Canada. He was fully into the store anti-theft systems and used to go down to shopping malls with a frequency meter disguised as a Walkman. From this, he worked out the frequencies the various makes of RFID systems in use, what kind of transmission they employed and other technical points. Quite why he wanted this information he didnít say!  Anyway at the time, I was quite keen on the idea of RFID, and very nearly bought a second-hand store system from a firm in Liverpool.

But I digress...

Tony proposes two uses for RFID:-

  1. Timing

  2. Dog identification

Race for time
RFID systems are often used for timing competitors in marathons and road racing. The athletes have a transponder fitted to the tops of their shoes or around their ankles. The transponder is read when the runners cross a mat which has the reader aerials incorporated in the fabric. The short range - top to bottom of shoe - is pretty well the same for every athlete and gives constant results.

A dog jumping is much more like an unguided missile. I have a feeling that the size of the dog, the thickness of its fur, the weather, the wetness of the dogís fur, its height above the pole and its approach path, would all have an effect on the range between dog and pole and thus the accuracy of the timing. However, there may well be equipment out there that would overcome these unknowns.

The problem here would be to ensure that the supply and fitting of personal collars on the dogs - and presumably tags on the handlers - did not become hard work logistically.  How many collars would a dog need for one Show?  This would presumably depend on the memory size of the transponder. It seems much simpler to me to supply ring cards, which nowadays have a lot of information on them, and then to go paperless. To operate electronically the ring would only need a running order number, which is available on the ring card.  On entering this into the ring computer, all the information previously stored on that dog/handler combination is opened. The time is taken from the timing set and faults from a scriber (or the judge - possibly by a virtual reality glove!) and entered in the results file against the running order number.  This file would be sorted, at the end of the class, into place order.

There are quite a few systems in the continent of Europe and the USA using this method, but they are expensive and are generally only used for top competitions. I think the near future will see the simplification of these systems, particularly to make them cheaper.  I would love to venture into RFID, but I donít think agility is the right dog sport for it.  Now, how about putting on a dog marathon?

About the author...
On the evening Martin Pollard started agility, by using his usual grace and dexterity, he demolished a very sturdy pause box. The resulting embarrassment drove him to replace the broken parts, and thus started Alvah Developments, which made agility equipment form 1988 to 1996.

His first dog Mac-C, a bitch Border Collie-Irish setter X, was followed by Judy, a superb agility dog, who rose to the ranks of Senior by ignoring all Martin's instructions. 

After two years Open University, Taryntimers came into being in 2000.
