Abstract

Использование: дл  контрол  прохождени  предметов мимо оптического датчика и может быть использовано в автоматических системах контрол  и управлени . Сущность изобретени : датчик прохождени  метки содержит фотоприемник 1, формирователь 2 и два элемента И-НЕ 3 и 4, импульсный светоизлучатель 6, генератор коротких импульсов 7, два инвертора 8 и 9, дополнительный элемент И-НЕ 10, дополнительный формирователь 11 и счетчик 12. Благодар  тому, что устройство обеспечивает работу в импульсном режиме светоизлучател , причем в промежутках между импульсами оно нечувствительно к помехам, а кратковременные прерывани  светового потока или помехи на выходе формировател  не нарушают работу устройства, обеспечиваетс  более высока  надежность в работе. 2 ил.Usage: to control the passage of objects past the optical sensor and can be used in automatic control systems. The inventive label passing sensor includes a photodetector 1, a shaper 2 and two NAND 3 and 4 elements, a pulsed light emitter 6, a short pulse generator 7, two inverters 8 and 9, an additional NAND 10 element, an additional shaper 11 and a counter 12 Thanks to the fact that the device provides pulsed operation of the light emitter, moreover, in the intervals between pulses, it is insensitive to interference, and short-term interruptions in the light flux or interference at the output of the driver do not interfere with the operation of the devices a, provides higher reliability in operation. 2 ill.
