“Draw gate-level elevator interlock logic with car call, door closed, door locked, overload, inspection mode, and at-floor inputs, producing RUN_ENABLE and DOOR_OPEN_ENABLE outputs.”
Leggi le decisioni che ne stanno alla base.
Both closed and locked door signals are required for movement.
Overload and inspection mode inhibit normal operation.
An at-floor signal prevents a normal run command.
Door opening requires the car to be at a floor and not overloaded.
Use this for a digital logic or controls exercise. Actual elevator safety chains use redundant, monitored, safety-rated circuits beyond this conceptual gate diagram.

Domande frequenti
Why need both door closed and locked?
They represent distinct conditions; a closed door is not necessarily mechanically locked.
What does inspection mode do?
It inhibits normal automatic motion in this simplified model.
Is overload normally a gate input?
An overload condition commonly prevents normal operation, though implementation is equipment-specific.
