1. What is AFC?
AFC (Automatic Fare Collection) systems automate ticketing, fare validation, payment clearing, and revenue management, significantly improving passenger flow and operational efficiency. Industrial switches serve as critical data hubs, connecting gate machines, ticket vending machines, and central servers to ensure real-time, accurate command and transaction delivery.
2. Industry Challenges
Urban rail transit AFC systems face three core challenges:
✅ Environmental Resilience
Industrial-wide temperature (-40°C~85°C), anti-vibration, and EMI-proof designs.
✅ Sub-50ms Self-Healing
Hybrid ring topology (RSTP/ERPS) ensures real-time reliability.
✅ Iron-Clad Security
Layer 2/3 VLAN isolation secures financial data streams.
✅ Smart O&M
Unified self-developed platform for remote management.
