<p>The present invention relates to an interlock circuit for a main control device in an operator room of a high-speed train, and more specifically, to a circuit for interlocking a main control device in an operator room to prevent a danger to safe operation of a high-speed train if an operator makes an operational mistake and a person other than the operator incorrectly operates the main switch and a control device in the operator room. The interlock circuit for a main control device in an operator room of a high-speed train according to an embodiment of the present invention classifies relays linked with a operator room selection switch into a relay (a first relay) to excite a car selected by an operator room, a relay (a second relay) to excite all operator rooms, and a relay (a third relay) to excite a car not selected by an operator room to connect the classified relays to the operator room selection switch. The second relay and the third relay are connected to an operator room of a control car on an opposite side through a connection cable. The operator room selection switch is connected to an electronic latch of an operator room selection switch disposed in the control car on the opposite side through the connection cable and a contact point a of the second relay to excite the electronic latch of the operator room selection switch disposed in the control car on the opposite side if the operator room selection switch is switched on to render the operator room selection switch disposed in the control car on the opposite side inoperable.</p> |
