摘要
随着北斗卫星导航系统发展,已有大量北斗短报文在地质灾害频繁区段进行应用数据传输的相关研究,如何分析其安全性成为能否工程应用的关键.采用FMEA给出基于北斗短报文的应用数据安全分析方法,以保证数据的正确性为出发点,分析可能的失效模式,尤其是数据变化带来的风险,根据失效模式,给出相应的风险减轻措施,来预防或减轻风险.从而为北斗短报文在未来轨道交通领域的广泛应用提供安全助力,以提高系统整体安全性.
Abstract
With the development of Beidou navigation satellite system,a large number of studies have been conducted on the application data transmission of Beidou short messages in areas with frequent geological disasters.How to analyze its safety has become the key to engineering application.In this paper,FMEA is used to provide an application data safety analysis method based on Beidou short messages.In order to ensure the correctness of data as the starting point,possible failure modes are analyzed,especially the risks caused by data changes.According to the failure mode,the corresponding risk mitigation measures are given to prevent or mitigate the risks.This will provide safety assistance for the wide application of Beidou short message in the future rail transit field to improve the overall safety of the system.
