The four buttons and the button relay are matched to control the two switching relays to suck or fall down, and the control of the multi-linked shared turnout is realized. As shown in fig. 2, 3 and 4, the control process is as follows:
pressing the first button LS1A, no matter which set of interlocking devices are switched on before switching, the excitation circuits of the first switching relay QHJ1 and the second switching relay QHJ2 are switched off, the first switching relay QHJ1 ↓ and the second switching relay QHJ2 ↓areswitched on the first interlocking LS1 control circuit, the other three interlocking control circuits are switched off, switching is performed to the first interlocking LS1 control circuit, and the first interlocking LS1 device obtains the turnout control right.
Pressing the second push button LS2A pops up the other three push buttons, the first switching relay QHJ1 ↓ and the second switching relay QHJ2 ↓ and turn off the other three interlock control circuits, turn on the second interlock LS2 control circuit, and the second interlock LS2 device obtains the switch control right.
The third button LS3A is pressed to bounce other three buttons, the button relays LS3AJ ×) suck up, the first switching relay QHJ1 ↓afterthe excitation circuit of the first switching relay QHJ1 is disconnected, the second switching relay QHJ2 ×) after the excitation circuit of the second switching relay QHJ2 is connected, other three interlocking control circuits are disconnected, the third interlocking LS3 control circuit is connected, and the third interlocking LS3 device obtains the turnout control right.

when the mutual exclusion switching circuit fails, the first switching relay QHJ1 and the second switching relay QHJ2 cannot be excited, the first interlock LS1 control circuit is switched on, and it is guaranteed that at least the first interlock LS1 equipment can control turnouts under any condition.
When the four push buttons are pressed simultaneously, as long as the first push button LS1A is pressed, the excitation circuits of the first switching relay QHJ1 and the second switching relay QHJ2 are switched off, the first switching relay QHJ1 ↓ and the second switching relay QHJ2 ↓areswitched on, the control circuit of the first push button LS1A is switched on, and the first interlock LS1 device can control the turnout.
When the third button LS3A and the second button LS2A are pressed simultaneously, since the eighth set of rear contacts of the button relay LS3AJ are connected in series in front of the second button LS2A, at this time, after the third button LS3A is pressed, the button relay LS3AJ is energized, the negative electric KF of the second button LS2A is turned off, only the second switching relay QHJ2 is energized, the second switching relay QHJ2 ↓isenabled, and the first switching relay QHJ1 is energized, so that the first switching relay QHJ1 ↓isenabled, only the third interlock LS3 control circuit is enabled, which has the same effect as that of only pressing the third switching button LS 3A.
When the second and fourth buttons LS2A and LS4A are pressed simultaneously, there are two excitation circuits: KZ-LS1A (Bounce) -LS3AJ1-QHJ1-QHJ2-LS3AJ5-LS4A (Down) -KF; KZ-LS1A (Bounce) -LS3AJ1-QHJ1-LS3AJ8-R-LS2A (Down) -KF. And a resistor R is connected in series between the eighth group of front contacts of the button relay and the normally open contact of the second button. Since a 1k Ω resistor R is connected in series in the (pressed) path of the second switching button LS2A, the excitation of the second switching relay QHJ2 is not affected. At this time, the first and second switching relays QHJ1 ↓and QHJ2 ×) and the fourth interlock LS4 control circuit are turned on, and the same effect as the switching button of the fourth interlock LS4 is pressed.
When the third push button LS3A, the second push button LS2A and the fourth push button LS4A are pressed simultaneously, since the eighth group of rear contacts of the push button relay LS3AJ are connected in series in front of the second push button LS2A and the fifth group of rear contacts of the push button relay LS3AJ are connected in series in front of the fourth push button LS4A, at this time, after the third push button LS3A is pressed, the push button relay LS3AJ is excited and attracted, the negative terminals KF of the second push button LS2A and the fourth push button LS4A are turned off, only the excitation circuit of the second switching relay QHJ2 is turned on, the second switching relay QHJ2 ↓isturned off, the excitation circuit of the first switching relay QHJ1 is turned off, the first switching relay QHJ1 ↓, only the control circuit of the third interlock LS3 is turned on, and the effect is the same as that only the third push button LS3A is pressed.
Therefore, no matter the exclusive switching circuit breaks down or takes place that a plurality of buttons are pressed simultaneously, all have and only an interlock acquires the control right of switch, the guarantee switch can be controlled by the interlock, a plurality of interlocks simultaneous control switch can not appear, lead to control command wadding in disorder, damage switch equipment, guarantee switch equipment safety work in order.
