Turnout Interlocking Protection Device for False Signal Prevention

The patent implements preliminary locking confirmation before turnout switching by activating locking confirmation relays (1K, 2K) that verify the current turnout position matches the target position. This preliminary verification action prevents false switching signals from being executed, as the switching command is blocked unless the confirmation relays are activated in advance to validate the switching conditions.

The patent employs feedback mechanisms through position detection circuits that continuously monitor turnout switch positions and feed this information back to the interlocking control system. The feedback signals from position detection relays (1S, 2S) and confirmation relays (1K, 2K) enable the system to verify whether switching operations were correctly executed and to prevent conflicting switching commands, thereby improving signal accuracy.

The patent applies preliminary anti-action by implementing interlocking protection that preemptively blocks false switching signals before they can cause harmful effects. The locking confirmation relays (1K, 2K) and position detection relays (1S, 2S) are activated in advance to verify switching conditions, and the circuit design ensures that conflicting switching commands are prevented from being executed, thus counteracting potential false signals before they impact the system.

The patent introduces intermediary confirmation mechanisms between the switching command input and the actual turnout switching execution. The locking confirmation relays (1K, 2K) act as intermediaries that mediate between the switching command and the position switches, verifying that the command is valid and the turnout is in the correct position before allowing switching to proceed. This intermediary layer filters out false signals while maintaining system versatility.
