摘　　要：为了改善基于GSM/GPRS的机车实时数据传输存在的信道宽带小、传输速率低、网络延迟和误码率高等不足,本文基于专门的3G传输装置,提出了一种具有机车状态数据接收、分析和评判等功能模块,并采用3G无线通讯技术将数据实时发送至地面服务器的系统方案,并设计了一种降低实时数据误码率的算法,实现了机车实时数据的高效传输。系统用户通过B/S模式访问该服务器数据,实现了对在途机车的实时监视和协同控制,为机车的安全运行提供保障。In order to overcome the disadvantages of small broadband,low transmission rate,network delay and high error rate in the locomotive real-time data transmission that are based on the GSM/GPRS,a system program is designed by using a special 3G transmission device,which includes locomotive status data reception,analysis and evaluation of the functional modules,and can send real-time data to the ground server by 3G wireless technologies.An algorithm for reducing real-time data error rate is developed to achieve efficient real-time data transmission.System users can access the server data by B/S model,monitor the online locomotive statue,and operate the locomotive cooperatively.This system has the potential to offer protection for the locomotive safety running.
