| Abstract: | 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. |
