Description

(54) УСТРОЙСТВО ЛОКОМОТИВНОЙ СИГНАЛИЗАЦИИ(54) DEVICE LOCOMOTIVE SIGNALING

При наличии на входе импульсной помехи, вызванной изменением т гового тока в рельсовой цепи, на входе локомотивных катушек образуютс  однопол рные импульсы, которые одновременно открывают или закрывают триоды амплитудных ограничителей.If there is impulse noise at the input caused by a change in the traction current in the track circuit, unipolar pulses are generated at the input of the locomotive coils, which simultaneously open or close the triodes of the amplitude limiters.

При изменении т гового тока в рельсовой цепн оба триода вход т в насыщение и с выходов их поступают одновременно сигналына вход сумматора 15, где происходит вычитание двух импульсов с одинаковыми амплитудами.When the current is changed in the rail chain, both triodes become saturated and from the outputs they simultaneously receive the signal input of the adder 15, where two pulses with the same amplitudes are subtracted.

Предмет изобретени Subject invention

Устройство локомотивной сигнализации, содержащее приемники с сумматором, амплитудный ограничитель и полосовой фильтр, соединенный с исполнительным элементом через усилитель, отличающеес  тем, что, с целью повышени  помехозащищенности, вход сумматора подключен к выходам амплитудных ограничителей, а выход - ко входу полосового фильтра.A locomotive signaling device containing receivers with an adder, an amplitude limiter and a band-pass filter connected to the actuator via an amplifier, characterized in that, in order to increase the noise immunity, the adder's input is connected to the amplitude-limiter outputs and the output of the band-pass filter.
