具备车地传输能力的地铁列车HDLC数据侦听装置

Metro Train HDLC Data Listening Device with Vehicle-to-Ground Transmission Capability

文章通过分析上海地铁一号线列车DINBUS总线物理层、链路层,设计了具备车地传输能力的列车运行数据侦听装置。硬件由基于SOPC II的FPGA收发模块、STM32单片机、LTM收发模块构成;列车运行时,侦听装置将数据存储于Flash中,列车停靠车站时,单片机通过LTE收发模块以UDP协议发送数据至地面服务器。在上海地铁一号线列车对该装置进行了实车测试,能够实时获取列车运行数据,实现了设计目标。进一步开发数据分析软件,即可进行列车技术状态分析,为安全运行提供保障。

Based on the analysis of the physical layer and link layer of DINBUS bus in Shanghai Metro Line 1,a train operation data listening device with vehicle-to-ground transmission capability is designed in this paper.The hardware is composed of FPGA transceiver module based on SOPC II,STM32 single-chip microcomputer and LTM transceiver module.When the train is running,the listening device stores the data in Flash.When the train stops at the station,the single-chip microcomputer sends data to the ground server with UDP protocol through the LTE transceiver module.The device is tested on the train of Shanghai Metro Line1,and the train operation data can be obtained in real time,and the design goal is achieved.With the further development of data analysis software,the technical status of the train can be analyzed to provide a guarantee for safe operation.
