Interactive 2D Simulation: Automated FASTag Parking Access & Boom Barrier Relay

A long-range UHF integrated reader (such as the Hopeland HZ510 or Identium 12m Long-Range Reader) is mounted overhead or on a 2.5-meter side pole facing oncoming vehicles. Operating with a 12 dBi directional circularly polarized antenna, it projects a focused RF lobe across the approach lane. As the vehicle enters the detection zone (6 to 10 meters away), the passive windshield FASTag is energized and transmits its EPC in under 20 milliseconds, triggering the barrier before the vehicle comes to a stop.

Standard parking lanes incorporate dual magnetic induction loops cut into the asphalt: (1) Loop A (Presence Trigger) verifies a real metallic chassis is approaching, preventing pedestrians from waving stolen tags, and (2) Loop B (Safety / Anti-Smash) directly beneath the barrier arm. The barrier motor controller will not allow the boom arm to lower until Loop B detects that the vehicle has completely cleared the passage.

Yes. RFID Softwares parking middleware supports dual operational modes: (1) Private Campus / Residential Society Mode (managing authorized resident vehicles against an internal database), and (2) NETC Commercial Parking Mode (connecting via NPCI acquiring bank APIs to automatically deduct parking fees directly from the vehicle owner’s bank/FASTag wallet).

A complete single-lane installation consists of: an integrated 12 dBi UHF long-range reader, a high-speed brushless DC (BLDC) boom barrier with 1.2-second opening time, dual ground induction loop detectors, an industrial micro-controller with isolated relay outputs, a red/green LED traffic signal light, and an optional ANPR license plate camera for dual-factor verification.

The system pairs the UHF RFID read with inductive loop sequence logic. Once the authorized vehicle triggers Loop B and clears the barrier, the arm immediately commands a high-speed descent. If a second vehicle attempts to draft behind without an authorized read, the barrier remains in interlock, triggers an audible warning horn, and alerts security guards with high-resolution ANPR snapshots.
