Работа устройства осуществляется следующим образом.The operation of the device is as follows.

При появлении сигнала на питающем входе 11 распределителя 4 на его выходе 12 образуется стимулирующий сигнал и он через элемент ИЛИ 14 поступает через выход /5 на .входные клеммы систем регулирования и на входы элемента И 31. Этот же сигнал через элемент ИЛИ 22 и элемент И 20 запускает реле 19 времени. При этом через элемент ЗАПРЕТ 10 включается индикатор 5 «контроль идет».When a signal appears on the supply input 11 of the distributor 4, a stimulating signal is generated at its output 12 and it enters through the OR 14 element through the output / 5 to the input terminals of the control systems and the inputs of the And 31 element. The same signal through the OR 22 element and And 20 starts the time relay 19. In this case, through the element BAN 10, the indicator 5 “control goes” is turned on.

В случае исправной работы систем регулирования, после отработки стимулирующего воздействия на входах 24 систем регулирования должны появиться сигналы, которые будут присутствовать на входах элементов И 31, которые включаются и через элементы ИЛИ 3 закрывают элементы ЗАПРЕТ 2. Таким образом индикаторы 1 не будут подготовлены через элементы 33 и элементы И 30 к включению. Это означает, что в .первом цикле контроля ни по одному каналу не произошло.In the case of correct operation of the control systems, after working out the stimulating effect at the inputs 24 of the control systems, signals should appear that will be present at the inputs of the AND 31 elements, which will turn ON and through the OR 3 elements will close the BAN elements 2. Thus, indicators 1 will not be prepared through the elements 33 and elements And 30 to inclusion. This means that in the first control cycle, no channels have occurred.

Затем через время, определяемое реле 19 и которое больше времени полной перекладки исполнительных механизмов систем регулирования, сигналом с выхода реле 19 времени через формирователь 28 распределитель 4 переводится во второе состояние, при котором сигнал на его выходе 12 пропадает, а на выходе 17 появляется.Then, after the time determined by the relay 19 and which is longer than the complete shift of the actuators of the control systems, the signal from the output of the time relay 19 through the shaper 28 distributor 4 is transferred to the second state, in which the signal at its output 12 disappears, and appears at the output 17.

Процесс контроля во втором и в третьем цикле контроля аналогичен процессу в первом цикле с той лишь разницей, что стимулирующие сигналы подаются соответственно с выходов 17 и 13 распределителя и эти сигналы воздействуют соответственно через выходы 18 и 15 на системы регулирования, а сигналы из этих систем появляются соответственно на входах 25 и 24.The control process in the second and third control cycles is similar to the process in the first cycle, with the only difference being that stimulating signals are provided respectively from outputs 17 and 13 of the distributor and these signals act respectively through outputs 18 and 15 on the control systems, and signals from these systems appear at inputs 25 and 24, respectively.

В конце третьего цикла контроля сигналом с выхода 29 распределителя 4 через элемент НЕ 21 и элемент И 20 выключается •реле 19 времени, а также через элемент И 9 включается индикатор 7 «исправно» .и через элемент ИЛИ 26 и элемент ЗАПРЕТ 10 выключается индикатор 5 «контроль идет».At the end of the third control cycle, the signal from the output 29 of the distributor 4 through the element NOT 21 and the element AND 20 turns off • the time relay 19, and also through the element 9 the indicator 7 “works”. And through the element OR 26 and the element BAN 10 the indicator 5 turns off "Control is on."

В случае, если в каком-либо цикле в системах регулирования (в одном или .нескольких) возникла неисправность, т. е. на входах 24 и 25 не появились сигналы в течение времени, которое определяется реле 19, ;на выходах элементов ЗАПРЕТ 2 отказавших каналов оказывается сигнал, который включает элемент 33 этих каналов и в конце третьего цикла сигналом с выхода 29 распределителя 4 через элементы И 30 включаются индикаторы 1 отказавших каналов. При этом индикатор, 5 «контроль ΓΤΤΤΤΖΆ'Τ'ΧΚ τ»τζ τττΓνττ л «'ч'т’гчт л тхтт ττ.τιτ/ηπΆη £ ζζη'πτΛο пл через элемент ИЛИ 27 и элемент И 8 включается.In the event that in any cycle in the control systems (in one or several) a malfunction occurs, that is, at the inputs 24 and 25 no signals appear during the time determined by relay 19; at the outputs of the elements BAN 2 failed channels is a signal that includes an element 33 of these channels and at the end of the third cycle, the signal from the output 29 of the distributor 4 through the elements And 30 turn on indicators 1 of the failed channels. At the same time, the indicator 5 “control ΓΤΤΤΤΖΆ'Τ'ΧΚ τ” τζ ττττΓνττ l “'h''t'hht l thtt ττ.τιτ / ηπΆη £ ζζη'πτΛο pl through the element OR 27 and the element And 8 is turned on.

Возвращение устройства в исходное состояние происходит при снятии сигнала с входа 11 распределителя 4.The device returns to its initial state when the signal is removed from the input 11 of the distributor 4.

Таким образом, данное устройство позволяет производить полный контроль исправности систем регулирования, даже при возникших в первых циклах контроля отказах в системах, без дополнительного воздействия на устройство, а также получить полную информацию об отказавших каналах в конце всех циклов контроля.Thus, this device allows you to perform full control of the health of control systems, even in the event of failures in the systems that occurred in the first control cycles, without additional impact on the device, and also to obtain complete information about the failed channels at the end of all control cycles.
