(54) ЭЛЕКТРОННОЕ РЕЛЕ ПОСТОЯННОГО ТОКА(54) DC ELECTRONIC RELAY

Изобретение относитс к электронным устройствам систем автоматики, измерительной и вычислительной техники.The invention relates to electronic devices of automation systems, measuring and computing equipment.

Известно электронное реле посто нного тока, содержащее блоки управлени и питаЭИЕ , усилитель A direct current electronic relay is known, which contains control and supply units, an amplifier

Однако известное устройство не отличаетс высоким быстродействием.However, the known device is not very fast.

Известно электронное реле посто нного тока, содержащее модул тор, вход которого подключен к шине входных сигналов, выходко входу усилител переменного напр жени а управл ющий вход - к шине источника мооулирующего напр жени f23 .An electronic relay of direct current is known, containing a modulator, the input of which is connected to the bus of input signals, the output of the amplifier of the alternating voltage and the control input to the bus of the modulating voltage source f23.

Однако такое устройство отличаетс инерционностью , что обусловлено необходимостью интегрировани сигнала на выходе демоаулатора . Кроме того, сказываетс вли ние переходш 1Х процессов в модул торе на чувствительность к входному сигналу.However, such a device is inert, which is caused by the need to integrate the signal at the output of the demo-watcher. In addition, the effect of the 1X transition processes in the modulator on the sensitivity to the input signal is affected.

Claims

The device contains a modulator 1, an amplifier 2 AC voltage, a block 3 of control voltage sources and a trigger 4 with logic elements ZI at the inputs. Unit 3 contains the buses of the source voltage source, the sequence source or another modulation frequency, and the common-mode and phase-phase modulating voltage source. The first inputs of the GI elements are connected to the output of the amplifier 2. In the initial state of the control input of the modulator 1 signal is not arrives, and the trigger 4 is set to a certain level. If the modulation and other signals appear on the tires 5–3 of the block 3. a module occurs. input signal, modulator 1, uiSH1enie-pdmodmodulrrvannogo ignvla amplifier 2 and the input. This signal is connected to the combined first inputs of the logic elements of the ZI trigger 4, at the same time the second and third inputs receive pulse sequences with a double modulation frequency, in-phase and a modulating one with modulating Duration: the double frequency pulses are minimal, but Sufficient for switching the trigger 4 , When the polarity of the input signal is changed, the polarity of the pulses at the modulator | 1 output changes and a change occurs in the trigger 4, and the triggering of three hera 4 is possible only at the moment of action cos not sovpadayushihpo time transients modulator 1, thus switching processes modulator 1 have no effect on the state of the circuit device that is -pozvol psivysigchuvstvitepnost. The absence of an intvi hr, link provides an increase in speed. Invention A direct current electronic relay comprising a modulator, whose input is connected to the bus of the input signal, the output of the AC voltage amplifier, and the control input to the source voltage of the modulating voltage is different. the fact that, for the purpose of increasing sensitivity and speed, a trigger with ZI logic elements at the inputs was additionally introduced, the source of a sequence of pulses with a double frequency MO, aulntia, and the source infaenog, o and antiphase modulating voltage, the first inputs of the GI logic elements are connected to the output of the AC voltage amplifier, the second input is connected to the source bus of a sequence of pulses with a double modulation frequency, the third input of the first GI logic element is connected to the N1 of the modulating voltage source and the third the input of the second is antiphase modulating voltage.
