Устройство работает следующим образом .The device works as follows.

В- нормальном режиме на выходе элемента 24 по вл етс сигнал логической еди- ницы, который переключает в единичное состо ние триггер 27, который фиксирует начало интервала рабочего сигнала дл одной рельсовой линии. Сигнал логической единицы с выхода триггера 27 поступает на входы элементов 15 и 16. In the normal mode, the output of element 24 is a logical one signal, which switches to one state trigger 27, which records the beginning of the working signal interval for one rail line. The signal of the logical unit from the output of the trigger 27 is fed to the inputs of the elements 15 and 16.

В конце цмкла опроса по сигналу сброса , формируемому на выходе распределител 23, сбрасываютс триггеры 17-19, триггер 27 находитс в сброшенном состой- нии, а положение триггера 21 соответствует состо нию рельсовой линии в течение цикла опроса. После окончани импул.ьса в рельсовой линии взводитс триггер 27, фиксирующий начало рабочего интервала в цик- At the end of the polling cycle, the reset signal generated by the output of the distributor 23 is reset by flip-flops 17-19, the flip-flop 27 is in diminished stability, and the position of flip-flop 21 corresponds to the state of the rail line during the polling cycle. After the end of the impulse in the rail line, trigger 27 is cocked, which fixes the beginning of the working interval in

Claims

From this point on, the output of the threshold element 12 through element 15 is connected to the setup input of trigger 18, which fixes the impulse noise in the working interval above the trigger threshold of element 12. The presence of continuous interference is detected by trigger 19 through element 16 during the working interval at the moments of signal arrival from the output of the distributor 23 to the input of the element 16. In this case, if the make-up takes place, then the signal of the logical unit from the output of the element 16 is fed to the input of the trigger 19, which fixes continuous interference, which It is entered. If during the working interval at the input of the threshold elements 12 and 13 there are no pulsed and continuous noises, then the triggers 18 and 19 remain in the reset state. At the end of the working interval, the trigger 27 is reset. In the next period of time, from the output of the distributor 23, a control pulse arrives at the switching element 2 of the transmitter, and the inputs of elements 14 and 26 of the switching element 2 follow the pulse of the signal current with a rail lynch. The signal current impulse comes from the inputs of the threshold elements 12 and 13. If the amplitude of the signal pulse is greater than the response threshold of element 13, then from its output the signal of the logical unit enters the input of element 14 and the signal from the output of the distributor 23 triggers the signal - horo pulse above the trigger threshold of the zleenta 13. Next, at the next time instant, trigger 21 is reset, and the information recorded in triggers 17-19 is read into trigger 21.
