Applications in on-board train systems
The Advantech EN50155 M12 certified switch meets a wide range of applications on moving trains, as it guarantees reliable performance against vibrations and shocks.
For Passenger Information Systems, it allows modules to communicate with LCD and LED display panels that offer travel information, news, and announcements (Figure 1).
For in-seat video entertainment systems, it offers video monitors mounted on the back of each seat. This allows all passengers to choose their own audio and video from on-demand movies, games, and travel entertainment.
And for video surveillance systems, this ensures reliable connectivity between these devices and cameras for a variety of applications, providing enhanced safety and security.
Station Applications:
Fire Alarm System.
When a disaster occurs, fire alarm systems (FAS) implement detection and send commands to switch extinguishing equipment from normal operating mode to emergency mode, coordinating subsystems such as traffic control, disaster relief, and security to minimize losses. The backbone network uses a redundant fiber optic ring with a maximum self-healing time of 10 ms (Figure 2).
Automatic Fare Collection
In modern train stations, Automatic Fare Collection (AFC) includes ticket vending machine systems, ticket checking machines, and access gate control systems that require layer 2 and 3 switches that can ensure a fast, reliable, secure, and redundant network (Figure 3).
Passenger Information Systems
The Advantech industrial switch and serial device server as the central communication system of Passenger Information Systems (PIS), allows train stations to control and transmit real-time information from their control center to all local stations with accurate travel information, (including train status, news, advertising, and emergency information) to improve travel in efficiency, safety, and ease (Figure 4).
Train control applications from cabs:
To control trains from trackside control cabs, specific controllers such as CBI, TCC, RBC, and TSRS are used to ensure uninterrupted operation. Advantech industrial Ethernet switches form a dual fiber optic ring network, and each controller is simultaneously connected to both of these fiber rings (Figure 5). Advantech's X-Ring technology ensures that a safety circuit is established in as little as 10 ms to compensate for errors such as broken links. This fully redundancy concept offers the highest possible level of safety.
