摘要
分析了基于GSM_R网络实现的机车同步操控系统,并针对此系统在数据传输方面提出的两个主要指标:时延和丢帧率,研究给出了一套测试方案.并对该方案进行了试验,试验结果表明采用本文提出的测试方法,可以全面、合理的统计出这两个指标,此外对于整个通信网络质量也具有一定的评估效能.
This paper briefly introduces the Locotrol System based on GSM-R Communication Network. Two targets： time delay and frame loss rate was proposed according to the data transfer in this system. Also presents testing method and depending on it an experiment was made. The result indicates that by using this testing method it is comprehensive and reasonable to state the two targets. Additionally, this method can evaluate the quality of the whole communication system in some ways.
