DEVICE FOR MEASURING THE SKIER long jump from a springboard

摘要

The invention relates to sports equipment, namely, to the ski jumps. In an apparatus for measuring the skier jump length springboard 12 includes at least two rows of receivers 1 skier landing signal is installed along the zone 2 touchdown skier on the mount 9 touchdown amplifier 5 received signals, analog-to-digital converter (ADC 6) processor means 7 and 8 present information, the output of ADC 6 is connected to the input of the processor 7, whose output is connected to the inlet means 8 to provide information used by the receiver 1 of an acoustic signal, the apparatus further comprises ist 3 regular enrollment acoustic test signal, set in the landing zone 2 of the skier, and the analog switch 4, and outputs the acoustic signal receivers 1 are connected to the input of the analog switch 4, whose output is connected to the input of amplifier 5, whose output is connected to the input of the ADC 6; 3 as a source of the acoustic test signal used piezoacoustic emitter. Increases the accuracy and reliability of measurement jump length of the skier from the springboard 12 and the apparatus is simplified.
