Description
барабана срабатывает только реле 8 (величина сигнала, вырабатываемого генератором 3, недостаточна дл срабатывани реле 9).the drum only operates relay 8 (the amount of signal generated by generator 3 is insufficient to trigger relay 9).
При обрыве или коротком замыкании цепей датчика или неисправности других элементов предлагаемого устройства, передача сигнала от генератора прекращаетс и реле 8 обесточиваетс , а следовательно выдаетс сигнал о неисправности цепей, обеспечивающий полный самокгантроль работы устройства.If the sensor circuits are interrupted or short-circuited or other elements of the device in question are faulty, the signal from the generator stops and the relay 8 is de-energized, and therefore a circuit fault signal is issued, which ensures complete self-control of the device.

ратор, усилитель, анализатор и исполнитель ный блок, отличающеес тем, что, с целью повышени надежности, в качестве датчика использован микрофон, установленный, например возле обечайки барабана, реагирующий на частотный сигнал, сопровождающий опасную пробуксовку, подключенный одним концом к части вторичной обмотки трансформатора , воспринимающего сигналы генератора , а другим через усилитель - ко входу анализатора, соединенного с исполнительным блоком, содержащим трансформатор, ко вторичной обмотке которого подключены последовательно исполнительные реле, настроенныеRator, amplifier, analyzer and executive unit, characterized in that, in order to increase reliability, a microphone is used as a sensor, installed, for example, near the drum shell, reacting to a frequency signal accompanying a dangerous slip, connected to the secondary side of the transformer at one end receiving the signals from the generator and through the amplifier to others - to the input of the analyzer connected to the executive unit containing the transformer to which the secondary winding is connected to the secondary winding of executive relays are configured
соответственно на сигналы микрофона и генератора .respectively on the microphone and generator signals.
