Abstract

Изобретение относитс  к области передачи информации и может быть использовано при построении систем управлени  электропотребител  ми, рассредоточенными по силовой цепи посто нного напр жени , проводники которой используютс  в качестве информационного канала. Целью изобретени   вл етс  повышение информативности устройства за счет увеличени  числа приемных узлов при двухпроводной структуре линии св зи. Устройство содержит проводники 1, 2 двухпроводной линии св зи источник 3 питани , 1 датчик 4 напр жени , стабилизаторы 6, 13 напр жени  шифратор 7 команд, преобразователь 8 параллельного кода в последовательный, формирователь 9 синхроимпульсов, 1 делитель 10 напр жени , преобразователь 11 напр жени  в сигналы посто нного тока, 1 генераторы 5, 12 тока, фильтр 14, усилитель 15 напр жени , 1 селектор 16 синхроимпульсов , преобразователь 17 последовательного кода в параллельный формирователь 18 адресов , элемент 19 сравнени , дешифратор 20 команд, элемент 21 оптической разв зки, усилитель 22 тока, элемент 23 коммутации и один трансформатор. При передаче информации команда в виде n-разр дного параллельного кода с выхода шифратора 7 команд поступает на вход преобразовател  8 параллельного кода в последовательный, который далее преобразуетс  в сигналы напр жени , поступающие на входы приемных узлов . В приемном узле последовательный код преобразуетс  в параллельный, который сравниваетс  с адресным кодом. В случае равенства кодов элемент 19 сравнени  соответствующего приемного узла через дешифратор 20 команд и элементы гальванической разв зки формирует управл ющий сигнал на элемент 23 коммутации, осуществл ющий подключение или отключение электропотрсбител , 1 ил. (Л СThe invention relates to the field of information transfer and can be used in the construction of power management systems dispersed over a constant voltage power circuit, the conductors of which are used as an information channel. The aim of the invention is to increase the information content of the device by increasing the number of receiving nodes with a two-wire communication line structure. The device contains conductors 1, 2 of a two-wire communication line, power supply 3, 1 voltage sensor 4, voltage stabilizers 6, 13, encoder 7 commands, parallel-to-serial code converter 8, clock generator 9, 1 voltage divider 10, voltage converter 11 DC to DC signals, 1 current generators 5, 12, filter 14, voltage amplifier 15, 1 clock pulse selector 16, serial code converter 17 to parallel address generator 18, comparison element 19, command decoder 20, element 21 optical isolation, current amplifier 22, switching element 23 and one transformer. When transmitting information, the command in the form of an n-bit parallel code from the output of the command encoder 7 is input to the parallel code converter 8 into a serial one, which is then converted into voltage signals supplied to the inputs of the receiving nodes. At the receiving node, the serial code is converted to parallel, which is compared with the address code. If the codes are equal, the comparison element 19 of the corresponding receiving unit, via the command decoder 20 and the galvanic isolation elements, generates a control signal to the switching element 23, which connects or disconnects the electric power cutter, 1 ill.
