ALPINE SKIING
System Overview:
Alpine ski racing requires the accurate recording of both start and finish times for each competitor. It is normal to have more than one competitor on course at any time. Sometimes a competitor will overtake another and a number of competitors can cross the finish at the same time. Competitors leave the start at set intervals, which can be adjusted (shortened/lengthened) during the course of the race. Spectators need to be informed of times and ranking during the race. For FIS Competitions and higher, electronic backup (System B) as well as hand timing (System C) are required.
System description:
The ALGE alpine skiing timing system consists of a TdC 8000 Timedata Computer able to record up to 10,000 competitors on course at any time. This device caters for all your needs including multiple competitors on course, simultaneous starts and finishes, overtaking competitors and multiple riders finishing at the same time.
The start is connected via a single pair wire which is used to transmit start impulses and full duplex communication between the starter and TdC 8000 operator using a Headset Q34 and Speech Amplifier SV4 at the start and a Headset Q34 plugged into the TdC 8000 at the finish. Start impulses come from an ALGE Start Gate STScM1S, STScM2S or STS3Q.
Start intervals are controlled using an ALGE Startclock ASC1 or ALGE Start Beep. The ALGE Startclock ASC1 is set in front of the start line on a Manfrotto Tripod or post. The analogue clock face, red/green start indicators and audible tones give skiers a clear indication of when to start. The start interval can be adjusted even during the race as required using an optional remote control box and cable.
The ALGE Start Beep can also be used giving an audible start sequence at a variety of preset or user defined intervals.
A separate Photocell RLS1n is set up on the finish line for each system to record each skier as they cross.
With a pair of GAZ 4 displays, the bib number and running time for each competitor can be displayed as the approach the finish line, as they cross the finish, the run time will be displayed along with bib number and rank.
Finish time of each skier can be sent via one of the TdC 8000's RS-232 serial ports to a PC for creation of results.
An additional TdC 8000 Timedata Computer, ALGE S4 or Timy or Comet can be used for system B and either a Timy or Comet using the Memotimer program can be used for hand timing.
Up to 8 Intermediate times can be recorded using (for each intermediate point) a single pair wire attached to an ALGE Photocell Adapter LA4, with a Push button which allows an official to enable the photocell when a skier is about to pass, and a Headset Q34 to communicate to the TdC 8000 operator.
