Signaling about the transition of the mechanism from one position to another does not confirm the execution of the sent komavda nz stop and, therefore, there is no confidence in the possibility of transition to the execution of another operation.

Устройство при использовании его дл сигнализации состо ни I-IM с реВерсивньм приводом работает следующим образом.The device, when used for signaling an I-IM state with a revived actuator, operates as follows.

Особенность сигнализации состо ний . ИМ с реверсивным приводом заклю- чаетс в том, что поступающие с шин Пуск на закрытие и Пуск на открытие сигналы могут быть кратковременными (дл исключени повторного автоматического запуска механизма при самовозврате сработавшей заш,иты) . Сигнал с шины Стоп поступает в течение всего периода, когда механизм не работает . Одновременное поступление сигнсшов с шин Пуск на закрытие, на открытие и Стоп исключено , т.е. сигнал может быть на одной из трех указанных пгик.State alarm feature. MI with reversing drive is that the signals coming from the buses Start-to-close and Start-to-open can be short-term (to prevent the mechanism from re-starting automatically during self-resetting of the protection). The signal from the bus Stop comes during the entire period when the mechanism is not working. Simultaneous receipt of signnshov from tires Start to close, to open and Stop is excluded, i.e. The signal can be on one of the three indicated blinks.

В качестве исходного состо ни ИМ примем закрытое состо ние, которое характеризуетс наличием сигналов на .шине Стоп, формирователе ИМ закрыт и инверсном выходе триггера 1. Сигнал с шины Стоп поступает на вход элемента НЕ 5 (следовательно на его выходе сигнала нет) , а также на первый вход дополнительного злемента И 4. На второй вход этого элемента сигнал не поступает, так как на первом входе элемента ИЛМ-НЕ 2 есть сигнал от формировател ИМ закрыт , поэтому на эь1ходе дополнительного элемента И 4 сигнала также нет.We take the closed state as the initial state, which is characterized by the presence of signals at the Stop bus, the MI driver is closed and the inverse output of trigger 1. The signal from the bus Stop is fed to the input of the HE element 5 (therefore there is no signal at its output), and At the first input of the additional element I 4. The second input of this element does not receive a signal, since at the first input of the element ILM-HE 2 there is a signal from the IM driver closed, so there is also no signal at the additional input of the 4 element.

Сигналы с инверсного входа триггера 1 и от формировател ИМ закрыт поступают соответственно на первый и.второй входы элемента И 6, а сигнал с выхода этого элемента поступАет через элемент ИЛИ 11 на усилитель 13, обеспечива тем самым ровную подсветку сигнального табло 15, Это означает,, что ИМ закрыт рт состо ние его соответствует командному сигналу. Выходные сигналы на элементах И 7-10 отсутствуют.The signals from the inverted trigger input 1 and from the MI driver are closed, respectively, to the first and second inputs of the AND 6 element, and the signal from the output of this element comes through the OR 11 element to the amplifier 13, thereby providing an even illumination of the signal board 15, which means That the MI is closed, its state corresponds to a command signal. The output signals on the elements And 7-10 missing.

Claims

When the signal from the bus starts to open (signals if there are no other signals), trigger 1 is not converted to a stable rocTnHHHf, at which the nocTynaet signal from its direct output, regardless of whether the signal remains at its input. Until such time as the MI has moved away from the closed state, i.e. while the signal persists. The MI is closed, the presence of three input signals on the element I generates short-term signals at its output, which with the help of the element OR 1 and the amplifier 13 provide a flashing illumination of the signal panel 15. This means that the MI is closed, but its state does not correspond to the command signal . Elements 4, 6, 8, 9, and 10 have no output signals. After the mechanism departs from the closed state (the IM signal is removed, the signal is closed, but the signal is not received yet), both signals at the input of the OR-NO 2 oTcyTCTBinoT element, therefore, a signal is generated at its output J which, together with signals from the generator 3 and the element NOT 5 generates short-term signals at the output of the element AND 8, providing, by means of the elements OR I 12 and amplifiers 13, 14, a simultaneous flashing illumination of the signal boards 15 and 16. This means that the mechanism is in the intermediate (transition) state, S In the opening operation mode, there are no output signals for elements 4, 6, 7, 9, and 10. Stopping the MI in an intermediate position is characterized by the presence of a signal on the bus Stop. In this case, the output signal at the HE 5 element disappears, and the presence of two input signals at the AND 4 element generates a signal at its output, which through the OR 11 and 12 elements goes to amplifiers 13 and 14, thereby providing a simultaneous even illumination of signal boards 15 and 16, which means the mechanism stops in an intermediate position. The output signals on the elements And 6-10 no. When restarting the actuator, the IM on opening (closing) is de-asserted on the bus Stop and the state of the circuit elements fully corresponds to the transition state described above) in the operating mode, and the simultaneous backlighting of the signal boards 15 and 16 changes to one-time blinking backlight both scoreboards. After the full actuating of the MI (full open), the signal from the driver W is open, which leads to the removal of the signal at the output of the OR-NOT 2 element, this, in turn, leads to the removal of the flashing backlight of both the signal boards. The appearance of a signal on the bus Stop does not change this state of the circuit. The presence at the inputs of the element And 10 signals from the imaging device IM is open direct output of the trigger 1 forming the output of this element signal, which is the element OR 12 arrives at - the sill 14, thus providing an even illumination of the signal board 16. This means that the MI is open and its The view corresponds to the command signal. The output signals on the elements And 4, 6-9 are missing. The receipt of a signal from the bus Start-to-close puts the trigger 1 into a steady state, at which the signal from its inverse output comes in, regardless of whether the signal is kept at its input. Before the operation of MI, i.e. while the mechanism remains in the open state and, therefore, the signal from the imager is received, it is open to the element 9 and all input signals are received, and the short-term signals formed at the output of this element using the element OR 12 and the amplifier 14 provide a flashing light Signal Board 16. This means that the MI is open, but its state does not correspond to a command signal. The output signals on the elements And 4, 6, 7, 8 and 10 are missing. Considering the further operation of the device in this way, it can be verified that after the start of the actuator MI (after the signal disappears opened by it) both signal lamps go into the flashing light mode. The stopping of MI in intermediate position is signaled by an even illumination of both signal panels. The arrival of liM in the closed state (the spindle of MI is closed) is signaled by an even illumination of the signal panel 15. by the signal on the bus Stop the state of the circuit corresponds to the initial state. In use, we propose a “stop” device for signaling and gp-stops, the Stop bus is not connected, and the Start-to-Open tires. The Close-to-Close tires correspond to the Start and Stop buses in a known device. The proposed solution expands the functionality of the device and, while maintaining the number of indicative signs, increases the amount of information provided, which allows a higher level of hardware unification to be achieved and increases the reliability of control.
