LonWorksTM On Amtrak’s Acela Express
  • Introduction
  • Amtrak’s Original Goal
    • Reap some of the Benefits of the prolific use of micro-processor based systems
  • How
    • Specify the centralized collection of subsystem operation and status data
  • Why
    • Improve information availability
    • Thereby improving transportation operations, and,
    • Improve equipment turn-around time

LonWorksTM On Amtrak’s Acela Express
  • Introduction
  • Amtrak did not specify how to integrate data collection, only that it was to be accomplished
  • Why?
    • The integration of the data from the diverse subsystems in the industry is a difficult task
    • Potential System providers had diverse approaches as to how to accomplish this task

  • Players
    • Amtrak – End User
    • Bombardier
      • Systems Integration on Superliner II, NJ Comet IV, Kuala Lumpur Metro, & NYCTA R-142
    • Vapor Canada
      • Bombardier hardware supplier and industry experience
    • Echelon – LonWorksTM
      • System and equipment for industrial application
      • LonTalk protocol provides all 7 of the levels of the OSI model

  • Networks
    • Car Internal Network (CIN)
      • LonWorks Twisted Pair Transceivers
      • FTT-10A, 78kbps
    • Power & Brake SubNetwork (PBIN)
      • LonWorks Twisted Pair Transceivers
      • FTT-10A, 78kbps
      • Separated for Independent Traffic Control
    • Trainset Monitoring Network
      • Special Physical Layer

LonWorksTM On Amtrak’s Acela Express

Trainset Monitoring Network (TNET)

Token Bus Network

Industry-standard 50 ohm Shielded Twisted Pair

Based on IEEE 802.4,

except for physical layer

Hardened for environment

High Noise Immunity

High Voltage Open Circuit Withstand

Current Limit to control contact degradation

Opto-isolation to control inter-car voltage variations

Transfer speed ~ 170 kbps

  • System Variables
    • Train-wide Status
    • Subsystem Operational Status
    • Subsystem Analog Values
    • Maintenance Events
lonworks tm on amtrak s acela express10
LonWorksTM On Amtrak’s Acela Express
  • System Variables
    • Train-Wide Status
      • 480 VAC Available – prevent false maintenance events
      • No Active Cab
      • All Doors Closed
      • No Motion
      • Layover Mode
      • Master Door Control Station Side
      • Main Pressure Reservoir Ok – Prevent false events
      • Door Open Inhibit Active

  • System Variables
    • Subsystem Operational Status
      • Periodically transmitted variables, rate adjustable
      • 16 to 96 individual Operational Status bits
      • Some bits common to all systems
      • Some bits unique to each subsystem
      • Train Operational Values – speed, pressures
      • Car monitoring Unit forwards variables to the Displays
      • Car Monitoring Unit stores variables – rolling history

  • System Variables
    • Subsystem Analog Values
      • Non-essential for Train Operation,
        • Coach Interior Temperature
        • Battery voltage
        • Etc.
      • Display Unit requests value from Car Monitoring Unit
      • Car Monitoring Units sets a refresh rate for the variable from the specific Subsystem
      • Display Unit will state when variable is no longer needed
      • Car Monitoring Unit resets the refresh rate to zero

LonWorksTM On Amtrak’s Acela Express
  • System Variables
    • Maintenance Events
      • Fault Detection (I.e., LVPS Failed)
      • Maintenance Forecasting (I.e., Door slow closing)
      • Information (I.e., ATC C/O Active)
      • Manual Fault Entry (I.e., Broken mirror)
    • Type of Events
      • Set/Reset – (I.e., online/offline)
      • Pulse – (I.e., one time occurrence event)
    • Information
      • Code, Description, Type
    • Car Monitoring Unit tags with Date, Time, Etc.
