The rapid acceptance of Ethernet-based networking in transportation infrastructures is providing many subtle benefits to traveler’s worldwide. From modern conveniences like in-seat news and entertainment programming to video surveillance for increased safety, Ethernet-based networks are helping improving our commutes everyday.
Ethernet acceptance in transportation applications is becoming a displacement process, whereby Ethernet networks are rapidly replacing the original serial-based device networks or analog systems. According to a new ARC Advisory Group study, Ethernet switch adoption is on a steady rise through 2014 and beyond.
As the industrial switch market expands, Ethernet products are becoming increasingly tailored to meet the requirements of a wide range of rugged applications. Some of the latest trends include:
- EN50155 Certification: EN50155 certification guarantees devices to withstand vibration, shock, or interruption of voltage supply.
- IP67 Certification: Watertight and weatherproof cases help protect against mechanical stress, moisture, condensation, dirt, dust and vibration.
- Redundant Topology: Redundant ring architectures allow one Ethernet switch in the ring to be the primary master. One path is the forwarding path, while the other is the backup path. If one links fails, the primary ring master automatically activates the backup path.
Industrial Ethernet backbones offer high bandwidth to enable many IP-based applications in transportation applications, especially for passenger information systems, video entertainment systems, and video surveillance systems.
- For passenger information systems this allows modules to connect with LCD and LED display boards which offer travel information (train position, estimated arrival time, stop announcements and connections), news and advertisements.
- For in-seat video entertainment systems this offers video monitors mounted on the back of every seat. This allows every passenger to choose their own audio and video on-demand movies, games and travel information.
- And for video surveillance systems this guarantees these devices can reliably connect with cameras for a variety of applications that provide increased safety and security.
