摘要
GSM-R 铁路专用无线通信系统在我国的应用已经起步,其系统可靠性尚待实际营运的考验。本文应用故障模式影响分析法(FMEA)和故障树分析法(FTA)对 GSM-R 系统的可靠性进行了分析和评估, 针对话音业务和数据业务的阻塞问题以及切换与中断问题给出了相应的解决措施,并讨论了提高 GSM-R 系统可靠性设计的相关对策。
Although GSM-R specific wireless communication system has kicked off its way in Chinese railway, its system reliability is still unknown and waiting for practical verification.The paper analyzes and evaluates the reliability of GSM-R system by employing Failure Mode Effect Analysis(FMEA)and Fault Tree Analysis (FTA),gives some effective solutions to the voice and data blockage,handoff and interruption and presents related approaches for enhancing GSM-R system reliability design.
