Onboard PlS

Why 3onedata

• Diversified Layer2/Layer3 product forms; standard rack-mounted/wall/embedded switch products available
• Standard M12 interface to ensure stable and reliable connection on the train
• 3onedata industrial grade redundant ring protocol SW-Ring, self-healing time ≤ 20ms, while supporting STP/RSTP, ERPS, MRP and other ring protocols)

Pantograph-0CS System Monitoring

Pantograph-OCS System Monitoring

• Industrial-grade design for real-time data collection of the operating status of the on-board Pantograph-OCS system
• Enables WWAN (Wide Area Network) communication for serial and Ethernet remote devices
• Support dual power supplies, dual SIM cards, cellular WAN and Ethernet WAN and other redundancy mechanisms, intelligent switching backup
• Built-in various VPN encryption protocols, network firewall, DMZ settings, etc., to ensure "unlimited" security of data transmission in the cloud)

Automatic Train Control System

Automatic Train Control System

• The overall system adopts standard TCN architecture and uses standard Ethernet broadband network as the backbone, while achieving link redundancy and equipment redundancy to effectively enhance the reliability of the whole network
• Ethernet repeaters are used in the middle of the backbone to effectively reduce the overall network latency caused by the increase of backbone nodes
• The backbone ETB network meets TTDP, R-NAT as specified in IEC 61375-2-5
• Downlinked ECN networks meet the relevant standards of IEC 71375-3-4
• The entire network uses the Train Real Time Data Protocol TRDP for information interaction)

ISCS Integrated Supervisory Control System

ISCS Integrated Supervisory Control System

• Support 10 Gigabit dual-ring redundant core network, providing sufficient guarantee for transmitting high bandwidth data transmission bandwidth
• Support operation between -40~75℃ wide temperature, high EMC protection level, ultra stability
• Support STP/RSTP/MSTP, ERPS, MRP, SW-Ring, etc. with self-healing time ≤ 20ms
• IP40 protection level, fan-less design, supports dual power supply, fault free operation)
