Изобретение относитс к средствам дл спортивных измерений и может быть использовано дл регистрации перемещени спортивных объектов.The invention relates to sports measurement tools and can be used to record the movement of sports facilities.
Цель изобретени - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.
На чертеже приведена функциональна схема предлагаемого устройства.The drawing shows a functional diagram of the proposed device.
Устройство дл фиксации положени спортивного объекта содержит антенну 1, выполненную в виде петлевой периодической структуры, блок 2 измерени , блок 3 регистрации , элемент 4 взаимодействи с антенной , выполненный из ферромагнитного материала и имеющий средство креплени на спортивном объекте, источник 5 посто нного тока и усилитель 6.The device for fixing the position of the sports object comprises an antenna 1 made in the form of a loop periodic structure, a measurement unit 2, a registration unit 3, an antenna interaction element 4 made of a ferromagnetic material and having means of attachment on the sports object, a constant current source 5 and an amplifier 6
Устройство дл фиксации положени спортивного объекта работает следующим образом .A device for fixing the position of a sports object operates as follows.
Источник 5 посто нного тока подает в антенну 1 посто нный электрический ток, создающий посто нное магнитное поле в област х , непосредственно прилегающих к петл м антенны, например вдоль беговой дорожки стадиона.A constant current source 5 supplies a constant electric current to the antenna 1, which creates a constant magnetic field in areas immediately adjacent to the antenna loops, for example along a stadium treadmill.
При движении спортивного объекта 4 происходит пересечение последним магнитWhen the movement of the sports object 4 occurs the intersection of the last magnet
ного ПОЛЯ петель антенны 1, что приводит к изменению магнитного потока и, следовательно , по влению электродвижущей силы в цепи антенны. Возникающее напр жение обрабатываетс блоком измерени путем дифференцировани и усилени . Полученные на выходе блока измерени импульсы регистрируютс в блоке регистрации.antenna loop 1, which leads to a change in the magnetic flux and, consequently, the appearance of electromotive force in the antenna circuit. The resulting voltage is processed by the measuring unit by differentiation and amplification. Pulses obtained at the output of the measuring unit are recorded in the recording unit.
Изобретение позвол ет повысить точность измерени и упростить устройство.The invention makes it possible to increase the measurement accuracy and simplify the device.
