| 摘 要： | 动车基地调度集中系统实现了列车与调车作业计划管理、列车与调车作业自动进路集中控制、动车组位置自动识别与追踪、动车基地作业计划的优化调整等功能。该系统与计算机联锁系统、分散自律调度集中系统、管理信息系统及车号自动识别系统等存在大数据量的信息交互,因此设计开发了一款安全可靠的接口机,实现内外系统的大数据量双向隔离高速传输和协议转换功能。

| Abstract: | The Centralized Control System of EMU Maintenance Base provides the functions of train op- eration and shunting scheduling, automatic centralized control of train operation and shunting, automatic EMU identifieation and tracking. The system can communicate with computer interlocking system, CTC, AEI and Information Management System, and large amount of data exchange is generated among them. So, it is absolutely necessary to design and develop a safe and reliable interface machine to achieve bi-di- rectional isolated high-speed transmission of large amount of data and protocol conversion. |
