How to set up a BibTag Timing System
4.1. General
Every participant in a MYLAPS timed event wears a registered BibTag/MultiSports Tag containing a chip. When the Tag
comes in the vicinity of a detection mat, the Tag continuously starts sending out messages with its unique identification (ID).
The antennas in the detection mat receive these ID messages and transfer them to the Decoder. The Decoder determines
the BibTag time for each ID by calculating the received signal strength from that BibTag. This passing time is calculated to an
accuracy of at least 0.5 seconds.
The BibTag system can operate with multiple (up until 8 matts) and mats, and is responsible for:
•
Controlling the antennas in the mats
•
Keeping accurate time (via a GPS signal or via an internal clock)
•
Data collection and storage (chip codes and times)
•
Record a gunshot start so that the equipment can use this same start time as the official time
•
Passing data from the Decoders to a central results computer via internet (GSM) with MYLAPS servers, or directly via
an ethernet link
•
Synchronizing multiple Decoder times via GPS
NOTE:
The antenna field will stop detecting the Tag after a period of seconds if the tag remains within the antenna field (Time
between same Chip). This means that the Tag may be assigned a false start time if it has already been detected within the
antenna field previous to the start time. To prevent this, the tags detected within the antenna field at the official start time
will all receive this official start time.
