铁路安防数据记录器抗毁防护指标研究

Research on the Survivability Protection Index of Railway Security Data Recorder

铁路安防数据记录器数据对于事故调查具有十分重要的意义。列车发生事故时可能处在灾难环境中,因此开展铁路安防数据记录器抗毁防护指标研究十分必要。通过对国内外铁路安防数据记录器的法规标准、设计思路、试验方法等进行梳理,深入分析强冲击、穿刺、静态挤压、火烧、腐蚀浸泡、静压等指标的适用性,总结出各指标制定过程中需考虑的关键要素,并结合我国铁路实际情况和未来发展需求,提出安防数据记录器具体的抗毁防护指标以及后续研究建议。

The data of railway security data recorder is of great significance to accident investigation.The train may be in a disaster environment in case of an accident,so it is necessary to carry out research on the survivability protection index of railway security data recorder.By sorting out the regulations and standards,design ideas and test methods of railway security data recorders at home and abroad,the applicability of indexes such as strong impact,puncture,static extrusion,fire,corrosion immersion and static pressure is deeply analyzed,and the key elements to be considered in the formulation of each index are summarized,specific survivability protection indexes and follow-up research suggestions are put forward in combination with the actual situation and future development needs of railways in China.
