用于南非内燃机车车地无线通信的DRU设计

DRU design of vehicle-ground wireless communication for South African diesel locomotive

介绍了车地无线通信的数据处理单元DRU的工作过程,将机车实时性较高的重要数据信息处理整合后,利用车地无线通信技术传输到地面数据服务器,并记录保存关键数据,通过专门的解析软件进行离线分析,并对地面服务器发来的控制指令给出相应的反馈数据信息。

The paper introduces the working process of DRU(Data Record Unit)in the vehicle-ground wireless communication.After processing and integrating the important locomotive data information with high realtime performance,the data information are transmitted to the ground data server by using the vehicle-ground wireless communication technology,and the key data are saved and recorded.Then the key data are analyzed offline through the specialized analytic software,and the corresponding feedback data information is given according to the control command from the ground server.
