The on-board module is connected with the existing safety detection devices such as TCU, LCU and TAX box, through the serial interface bus, and realizes integrated data collection from electric apparatus and control system. The intercommunication platform between the locomotive and the ground is established based on the BEIDOU satellite and GPRS system; the former is used for distant communicating while the latter is used for massive communicating. The design of the ground supervision system is fulfilled.

制定了车载单元的串口总线协议，车载主控单元通过串口总线连接机车的微机控制柜、逻辑控制单元和TAX箱等现有独立的安全检测设备，实现对机车电器部件和控制系统运用状态信息的综合数据采集；综合采用北斗卫星通信和GPRS移动通信技术构建了机车与地面之间的双向数据通信平台，前者解决了在偏远地区的数据传输问题，后者解决了机车运用状态信息的大数据量传输问题。
