Description
Изобретение относитс к способам передачи индуктивных сигналов по телефонным лини м с применением числового кодировани разнопол рных импульсов тока.The invention relates to methods for transmitting inductive signals over telephone lines using numerical encoding of current-different current pulses.
Известны устройства дальнего набора индуктивными импульсами, каждый из которых состоит из двух посылок-положительной и отрнцатель го1 . Однако наличие сигналов с одним или даже двум индуктивными импульсами не обеспечивает требуемой помехоустойчивости аппаратуры и ограничивает область ее применени .Known devices are a long-range set of inductive pulses, each of which consists of two positive-positive premises and a reflector. However, the presence of signals with one or even two inductive pulses does not provide the required noise immunity of the equipment and limits its scope.
Цель данного изобретени -устранить указанные недостатки путем применени предварительных и исполнительных сигналов, различаюnuixc .H между собой пол рностью первого импульса и количеством импульсов в сигнале.The purpose of this invention is to eliminate these drawbacks by applying preliminary and executive signals, distinguishing between unixc .H between the polarity of the first pulse and the number of pulses in the signal.
Кроме того, с нелыо фиксации импульсов малой продолжнтельности . в устройстве дл приема индуктивных сигналов использовано трехпозиционное пол ризованное реле,во врем переключени кор которого зар жают конденсатор, а разр д его производ т затем через обмотку исполнительного реле.In addition, with the small fixation of pulses of low duration. In the device for receiving inductive signals, a three-position polarized relay is used, during the switching of the core of which the capacitor is charged, and then discharged through the winding of the executive relay.
