Monitoring Train Control and Management Systems (TCMS)
Monitoring and control using Multifunction Vehicle Bus (MVB), CAN and serial

Trains operators increasingly use predictive maintenance to ensure most efficient use of the train fleet. Technology on new trains such as LTE modems and Ethernet Train Backbone make this easier by interconnecting to onboard systems such as doors, air-con and brakes which can be monitored remotely.

 

 

 

While Ethernet bus technology as implemented in Ethernet Train Backbone is seen as the successor to IEC 61375, there are still many trains in service that rely on older circuit-based technologies such MVB, CAN and serial to monitor status of systems connected to these buses such as doors, air-con and braking systems. 

Accessing legacy systems remotely is more challenging.

Klas TRX R6 with its modular architecture can include multiple expansion cards to interface with devices on legacy buses. For example MVB could be used to monitor and manage onboard equipment such:

  • Doors: Opening, Closing, jammed…
  • Air Conditioning: Temperature, air flow, air quality…
  • Brakes: Status, temperature…
  • Toilet water tanks: Levels

Having gathered information from sensors, TRX R6 then establishes a secure VPN from train to operations center. This allows fault-finding and predictive maintenance to be carried out.

With TRX R6 being an open platform, it is easier than ever to take total control of your onboard devices using a single gateway to monitor status and even automate maintenance tasks.
