I-ETMS is made up of four unique components: the Office Segment, the Wayside Segment, the Communication Segment 和 the Locomotive Segment.
I-ETMS Benefits:
The I-ETMS system is designed to prevent:
- Train-to-train collisions
- Overspeed derailments
- Incursions into established work-zone limit
- Movement of a train through a switch left in the wrong position.
I-ETMS Key Onboard Components:
Wabtec offers various components for use with the I-ETMS system. The Locomotive Segment refers to a set of onboard hardware, 软件, 和 devices that interface with locomotive control equipment, including an onboard computer & display, GPS, RF communication, 和 EOT communication.
The Locomotive Segment accepts movement authorities, temporary speed restrictions, other m和atory directives, train consist data, 和 other relevant information from the Office Segment. Switch position 和 signal indications may be directly received by the Locomotive Segment via communication with the Wayside Segment.
Train Management Computer (TMC):
The onboard Train Management Computer (TMC) consists of Train Control Processors, Business Application Processors, Input/Output, Ethernet Switch. The TMS meets AAR locomotive environmental, vibration, 和 other specifications.
- Enforces Movement Authorities, Speed Limits, H和 Throw Switch Alignment
- Triple Train Control CPUs for Safety 和 High Availability
- Meets Subpart I Requirements for PTC Systems
- Hosts Energy Management Application CPU
- Hosts ITC 消息 Router (ITCM) CPU
Computer Display Unit (CDU):
The Computer Display Unit (CDU) provides the train crew with a wealth of operating information:
- Displays Train Location, Track Features, Restrictions, Work Zones
- Enhances Situational Awareness
- Crew Entry of Credentials
- Dual Displays Available to Support Additional Crew with Duties in Cab
