TETRA地铁列调车载台模拟器设计

摘要轨道交通无线通信系统是轨道交通内部固定人员之间进行高效通信联络的重要手段，本文主要通过对地铁数字集群通信系统的学习，对数字集群通信系统技术体制、系统组成和功能特点的分析，对地铁无线调度子系统的特殊需求进行了分析，提出了无线调度子系统车载台的设计方案。35432
     通过学习了解到TETRA 的设计主要是为专用网调度服务。地铁无线调度通信系统就是采用 TETRA 数字集群系统。在比较各种编译语言使用的难易程度和实现情况，选取vb作为本课题的编译语言。通过对列车车载台的功能分析后，选取了车载台直通模式与集群模式转换和读取组号功能，通过vb设计出了合理的人机界面，将产品的AT指令发送给车载台实现与车载台的联调功能，模拟了实际中车载台在地铁运行过程中通信调度的功能。
     通过这次课题完成了针对TETRA终端产品的AT指令的编写，完成对终端产品的调试。

The subway train radio system cab radio design
Abstract：Rail wireless communication system is an important means of rail traffic between internal fixation and efficient communications and liaison officers, the paper studies the subway digital trunking communication system, through the digital trunking communication system and technology system, system components, and analysis features, and on the subway wireless the special needs of the scheduling subsystem analyzes proposed scheduling subsystem wireless transceiver design. Digital trunking system in the success of the world depends largely on its own excellent performance.
         TETRA mainly private network scheduling network design. Metro wireless dispatch communication system is the use of TETRA digital trunking system, mainly for fixed radio stations, each train car radio, hand held scheduling capabilities to provide voice and data capabilities between the station and control station, to ensure traffic safety and emergency incidents have irreplaceable role, while providing an essential means of communication for each department.
        TETRA terminal products written for AT command instructions to complete the commissioning of the end product.
