A microcontroller-free automated parking management and barrier control system designed and simulated in Proteus Design Suite.
This project automates vehicle entry/exit monitoring, live parking occupancy counting, and barrier gate control using discrete digital logic ICs and sequential circuits.
- Simulation Tool: Proteus 8 Professional
- Technology: Digital Logic Design (Combinational & Sequential Circuits)
- Vehicle Counter (IC 74191): 4-bit synchronous up/down counter that tracks incoming and exiting vehicles.
- Display Decoder (IC 7447 / CD4511): BCD to 7-Segment decoder driving the common-anode display to show real-time occupancy.
- Motor Driver (L293D): H-Bridge driver controlling the DC motor-driven barrier mechanism.
- Debouncing & Inputs: Push buttons simulating sensor inputs (
CAR INandCAR EXIT) paired with RC debouncing networks. - Control Logic: Logic gates (OR, NOT) detecting maximum capacity (Count = 8) using the counter's MSB output.
- Vehicle Entry: Pressing
CAR INgenerates a pulse that increments the 74191 counter, updating the 7-segment display count. - Vehicle Exit: Pressing
CAR EXITpulses the counter in down-mode, decrementing the current count. - Full Capacity Trigger: When the vehicle count reaches 8, the Most Significant Bit (MSB) turns HIGH.
- Barrier Control: The HIGH logic level drives the L293D motor driver, rotating the motor to close the barrier gate and prevent further entry.
- Reopening: Once a vehicle exits and the count drops below 8, the motor reverses direction to open the gate.
