基于GSM-R的列控通信系统安全防控

Safety analysis of communication system in train control system based on GSM-R

为适应我国高速铁路列车通信的要求,我国采用全球领先的GSM-R通信系统作为高速铁路列车的移动通信系统。但由于网络结构和自身开发平台等的一些制约,GSM-R本身存在一定的安全风险。经过简单分析GSM-R通信系统的网络构成和工作原理,并针对GSM-R系统可能存在的安全风险从人为因素、设备因素、环境因素和管理因素4个方面应用事故树分析的方法得出安全风险的重要度并对每个重要度从高到低进行排序,最后对相应的危险因素提出风险控制措施。

In order to meet the requirements of China＇s high- speed railway train communication,our country adopts the GSM- Ras the mobile communication system of high- speed railway. But GSM- R itself has some certain safety factors,because of some restricting network structure and its development platform. This paper briefly described the network composition and working principle of the GSM- R system. From the aspects of human factors,equipment factors,environmental factors,and management factors,the possible security risks were also analyzed. This paper used method of fault tree the security risk and importance of each important degree from high to low ranking. Finally to analyze the risk control measures for the corresponding risk factors were put forward.
