Изобретение относитс к контропьн(измерительной технике, предназначено дл допускового контрол нетр женнй переменного и импульсного токов и может быть использовано в автсалатике, тепе- механике, в системах контрол зашиты и дл управлени технологическими процессами ..The invention relates to contropn (measuring technology, is intended for the tolerance control of non alternating and pulsed currents and can be used in automatic control, tepechanics, protection systems and for control of technological processes.
Известны устройства дл допускового контрол переменных напр5гжений, содержащие импульсный генера;гор, колебательные контуры, включенные в схему электрического моста, усилители, суммируюпше устройства и исполнительный орган fl .There are known devices for the tolerance control of variable voltages containing a pulse generator, mountains, oscillatory circuits included in an electric bridge circuit, amplifiers, summing up devices, and the actuator fl.
Однако указанные устройства критичны к частоте контролируемого напр жени и обладают низким быстродействием.However, these devices are critical to the frequency of the monitored voltage and have low speed.
Наибол.е |лизким к предлагаемому вл етс двухиороговое устройство, содержашее два пороговых элемента, два триггера, элементы совпадени и запрета , генератор тактовых импульсов и иополн хгельный орган ,2J .The most promising is a two-horn device, which contains two threshold elements, two triggers, elements of coincidence and prohibition, a generator of clock pulses and a full body, 2J.
Однако известное устройство обеспечивает получение лишь двух видов информацщс: Норма и Не норма , требует синхронизапви генератора тактовых импульсов с входным сигналом и обладает недостаточным быстродействием. However, the known device provides only two types of information: Normal and Not normal, requires synchronization of the clock generator with the input signal and has insufficient speed.
Целью изобретени вл етс повышение быстродействи и расширение функ10 циональных возможностей устройства за счет раздельного контрол верхнетчэ и нижнего уроеней напр жени . The aim of the invention is to increase the speed and expand the functional capabilities of the device due to separate control of the upper and lower voltage levels.
Поставлеина цель достигаетс тем, что устройство дл дсшускового контрол The goal is achieved by the fact that the device for the control of
15 переменных напр жений, содержашее пороговые элементы верхнего и нижнего уровней напр жени , выходы которых соединены с единичвьми входами соответствукшшх триггеров, и дифференцирующую 15 alternating voltages, containing the threshold elements of the upper and lower voltage levels, the outputs of which are connected to the unit inputs of the corresponding triggers, and differentiating
