Digital Transport Logistics Interoperable Electronic Train Management System I-ETMS

全球最大网赌正规平台’s I-ETMS (Interoperable Electronic Train Management System) system is a safety-critical overlay system that provides means to enforce movement authorities, 速度限制, 工作区域 和 switch positioning to help reduce the potential for train accidents. I-ETMS integrates new technology with existing train control 和 operating systems to enhance train-operation safety.

With I-ETMS, the crew remains in control of the train. The system monitors 和 ensures the crew’s compliance with all operating instructions, while the display screen provides the train crew with a wealth of operating information. 车载电脑, with the aid of an on-board geographic track database database 和 GPS system, constantly calculates warning 和 braking curves based on all relevant train 和 track information including speed, 位置, 运动机构, 速度限制, 工作区域, 并且包含限制条件. All information is combined 和 analyzed in real time to provide a “safety-net” for improved train operation

I-ETMS® also queries wayside devices, 检查断轨, proper switch alignment 和 signal aspects. I-ETMS can integrate with 全球最大网赌正规平台’s train management dispatch system, tmd®, a train control solution for all methods of operation including CTC, TWC, 直接转矩, 和PTC(列车自动控制系统).

    I-ETMS is made up of four unique components: the Office Segment, 路旁段, the Communication Segment 和 the 机车 Segment.


    The I-ETMS system is designed to prevent:

    • Train-to-train碰撞
    • 超速脱轨
    • Incursions into established work-zone limit
    • Movement of a train through a switch left in the wrong position.

    I-ETMS Key Onboard Components:

    全球最大网赌正规平台 offers various components for use with the I-ETMS system. The 机车 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 机车 Segment accepts movement authorities, temporary 速度限制, 其他强制性指令, 训练数据, 和 other relevant information from the Office Segment. Switch position 和 signal indications may be directly received by the 机车 Segment via communication with 路旁段.

    Train Management Computer (TMC):

    The onboard Train Management Computer (TMC) consists of 列车控制 Processors, Business Application Processors, 输入/输出, 以太网交换机. The TMS meets AAR locomotive environmental, vibration, 和 other specifications.

    • Enforces Movement Authorities, Speed Limits, H和 Throw Switch Alignment
    • Triple 列车控制 CPUs for Safety 和 High Availability
    • Meets Subpart I Requirements for PTC Systems
    • Hosts 能源管理 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
    • 船员入境证书
    • Dual Displays Available to Support Additional Crew with Duties in Cab
