情境
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.
這張圖裡有什麼
看懂背後的決策。
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.
