Automatic card swiping gate, subway card validation system

I. Core Gate Types and Application Scenarios

1. ‌Tri-Barrier Gates‌

   • ‌Structure‌: Three rotating bars with a 0.5-meter passage width; response time: 2-3 seconds‌
   • ‌Application‌: Standard subway station channels; cost-effective and highly durable, accounting for >70% of subway gates in China‌
   •  

2. ‌Flap Gates (Wide Passage)‌

   • ‌Design‌: 0.9-meter fan-shaped door with triangular structure for bulky luggage/strollers‌
   • ‌Special Function‌: Supports free passage for disabled veterans (manual override by staff) 

3. ‌Swing Barriers (Next-Gen)‌

   • ‌Upgrade‌: Rectangular door design increases throughput by 30%; anti-tailgating via unidirectional infrared sensors‌
   • ‌Safety‌: Auto-locks upon reverse intrusion; clamping force ≤2kg‌

4. ‌Normally Open Mode Gates (Pilot Innovation)‌

   • ‌Operation‌: Gates remain open; green arrow display post card-scan enables frictionless transit‌
   • ‌Pilot Cities‌: Shanghai (Zhanghuabang Station), Guangzhou (2024 launch); 40% peak-hour efficiency gain

II. Evolution of Smart Recognition Tech

1. ‌Multi-Modal Verification‌

   • ‌Baseline‌: RFID cards 
   • ‌Extensions‌:
     
     • Mask-compatible facial recognition‌
     • QR codes 

2. ‌Anti-Conflict Protocol‌

   • Manual deactivation needed when physical card conflicts with facial recognition‌
   • Foreign card payment systems use isolated channels‌

III. System Integration & Safety

1. ‌Triple Anti-Pinch Tech‌

   • Infrared monitoring + mechanical rebound + electromagnetic cutoff‌
   • Passage detection error <0.1s; tailgating ID rate >99.8%‌

2. ‌Smart Management‌

   • ‌Crowd Control‌: SuiTeng OS analyzes carriage density for real-time (diversion)‌
   • ‌Emergency Mode‌: Auto-switch to open mode during fires/earthquakes; manual override buttons‌
   • ‌Security Synergy‌: Gates integrated with AI (security gates) for suspicious behavior alerts

IV. Maintenance Optimization

‌Deployment Note‌: Card readers >30cm from metal objects; separate power/data cables (>20cm spacing)‌.

V. Future Development

• ‌Frictionless Passage‌: Biometric-payment integration.
• ‌Modular Upgrades‌: "Normally Open Mode" via software.
• ‌Smart O&M‌: Self-diagnostic systems with real-time fault alerts.
