Korenix Subway PIS Application
By: Korenix Technology
Advanced transportation system technologies such as Passenger Information System (PIS) are being widely deployed by many urban transit systems worldwide in order to improve efficiency, reduce operating costs, improve service quality and secure for passengers. To ensure the high quality of these information systems, reliable network infrastructures must be deployed with networking equipment, capable of resisting the unfavorable conditions of underground surroundings such as vibration and shock, dust, temperature changes and etc.
Korenix offered an ideal solution to above challenges – the JetNet 6910G-M12 PoE switch provides high power PoE connectivity to the power hungry devices as well as the JetNet 5010G managed switches for ensuring reliable high bandwidth data transmission in extended networks.
The JetNet 6910G-M12 high power PoE switch has been installed in the railcars to deliver up to 30W power per port and 100W per unit by IEEE 802.3at PoE to the high-end IP cameras and PoE-enabled monitors. Using the uplink gigabit ports, the switches with MSR network redundancy technology were capable of forming gigabit rings to transfer the high bandwidth video streams from the railcars to the control room and meanwhile collect from the rooms all the commands and information for displaying on LCD screens. The long distance connectivity between the railcars and the control room was achieved by the SFP combo ports of the JetNet 5010G managed gigabit switches, which allowed forming gigabit fiber networks.
The network reliability and real-time video and data transmission were further guaranteed by the Korenix patented RSR network redundancy technology with less than 5ms recovery time. With the advanced management features of the managed JetNet & JetPoE switches, such as QoS, optimized IGMP snooping, VLAN traffic isolation,…. Administrators were capable of ensuring the high quality and efficient video transmission. Moreover, using the LLDP and Korenix NMS, they automatically visualized topology and performed efficient network management while reducing overall maintenance efforts and costs.
With rugged M12 connectors and the wide operating temperature, the switches provided vibration/ shock protection and reliable data transmission in underground railways becoming the perfect devices for upgrading the PIS and improving passenger safety in modern subways.
