El escenario
An automated haul truck entry control system uses RFID tag detection and safety sensor inputs to synchronize traffic lights. A D flip-flop holds the entry-permit state, which enables the green light and gate opening while the truck is present, resetting when the truck clears the zone.
Qué hay en este dibujo
Lee las decisiones que hay detrás.
01
Using a D flip-flop to store the permission state for sequential control
02
Combinational next-state logic that sets/clears based on RFID and safety conditions
03
Buffered outputs to drive traffic light and gate signals with consistent state
Apply this pattern for safety-critical vehicle entry/exit systems requiring a simple sequential controller with explicit memory and combinational decision logic.
