Abstract
Изобретение относитс к импульсной технике и может быть использовано в устройствах противоаварийной автоматики, а также в системах контрол любых величин, преобразованных в частоту. Устройство дл допускового контрол частоты содержит формирователь 1 импульсов, ждущие мультивибраторы 2 и 3, элемент 4 запрета, триггеры 5-8, элементы НЕ 9 и 10, элементы И 11-13, входную шину 14, выходные шины 15-17. Исключение ложных срабатываний в устройстве позвол ет повысить функциональную надежность контрол входной частоты, измен ющейс в широких пределах. 2 ил.The invention relates to a pulse technique and can be used in emergency control devices, as well as in control systems for any values converted to frequency. The device for frequency control includes a pulse former 1, waiting for multivibrators 2 and 3, prohibition element 4, triggers 5-8, elements HE 9 and 10, elements 11-13, input bus 14, output buses 15-17. The elimination of false alarms in the device allows increasing the functional reliability of monitoring the input frequency, which varies over a wide range. 2 Il.
