Requirements

Industrial design, equipment operating resist rugged surrounding of strong electromagnetic interference

Efficient, reliable network redundant backbone transmission system

Quick backbone looped network couple topology with sub looped network

Precise power monitoring control system, power supply to train and vehicle-mounted devices continuously

The abilities of extra long distance transmission and extra high compatibility

All equipments meet with the international management standard, compatible to all levels management control platform

Solution

Deploy IS2000 and IS3000 GE Ethernet switches on traction substation, to connect with various protection relays and BUS equipment, for status data collection. According to the different requirements of operators, divide different VLAN for transformer substation, the network of neighbor transformer substation backup path each other, using GE fiber ports to form a protection ring, top-speed link recovery technology is supported, recovery time≤ 20ms, thus, enhance the uninterrupted network of data transmission, improved the reliability of network power.
