基于以可靠性为中心的维修理念,对列车自动防护(ATP)车载设备进行功能和故障模式分析,运用层次分析法(AHP)对某种类型的ATP车载设备故障影响程度进行定量评估.结果表明:TCR天线的故障影响程度最高,BTM的故障概率最高,应适当调整这两个设备的维修策略.说明AHP方法可有效运用于ATP车载设备的维修决策,可针对性的优化既有的通用维修模式. 相似文献

在CTCS-3级列控系统的仿真平台中,应答器作为关键的地面设备,需要给车载等地面设备提供定位信息和线路信息等,以保证列车的正常安全行驶,所以在正确的位置给车载设备发送应答器报文信息是很重要的。提出了一种仿真平台中减小应答器定位查找误差的算法,阐述了该算法的实现过程。仿真结果表明该算法减小了应答器定位查找的误差,是仿真中保证列车正常安全行驶的一种重要算法。Abstract： In the simulation platform of CTCS-3 system,the balise is the indispensable above-ground equipment which sends the localization information and the line information to the on-board equipment to guarantee traffic safety.It is very important to send the balise text in the correct position and opportunity.An algorithm was developed to reduce the localization search error when a balise was found in the simulation platform and this algorithm’s realizing process in the simulation platform was elaborated on.The result of the simulation indicates this algorithm can reduce the localization search error for balises,which is important in guaranteeing the normal and safe operation for trains. 相似文献
