摘要
随着列车运营速度的不断提升,高速列车的运行安全监控技术变得越发重要。从高速动车组的设计、运用和维修保障等方面出发介绍了高速动车组的安全保障体系,采用可靠性、冗余设计和诊断技术的车载安全技术,采用GPRS的动车组远程传输系统信息化技术、数据库诊断及专家系统的地面数据库技术,综合故障维修安全保障技术。以CRH3型动车组为例分别介绍了高速动车组的运行安全监控体系的构成,并提出了高速列车运行安全监控体系的研究方向。
With the increase of train operation speed,running safety monitoring technology of high speed train has gradually become more important.From the design,application,maintenamce and other aspects,this article introduces high speed EMV＇s safety guarantee system,which adopts the following techniques： onboard safety technology with reliability,redundancy design and diagnostic technology;infomation technology of EMU＇s longdistance wireless transmission system with GPRS;ground database tecchnology of database diagnostic and expert system;comprehensive fault maintenance safety guarantee techology. This article takes for example CRH3 EMU,introduces the structure of CRH3＇s running safety monitoring system and proposes research objectives and development trend.
