高速列车网络安全性分析与测试

高速铁路的发展对列车安全提出了更高的要求。随着信息化在列车上的广泛应用，列车网络控制系统在高速列车运行中的地位也越来越重要，保证列车网络的安全性和可靠性是列车安全运行的前提条件。通过研究CRH2型动车组列车网络设计结构，按照封闭传输系统通信安全标准EN50159—1对ARCNET协议网络的可靠性进行分析，探索提升列车网络设备的可靠性分析检测的方法。

Safety Analysis and Test on High-speed Train

The development of the high-speed railway has put forward the new requests for the train safety. As information technology widely used on the train, the control systems in high-speed train network is becoming increasingly important. Prerequisite for the safe operation of trains is to ensure that the train network security and reliability. This paper studies the security of CRH2 EMU network system according to the standard EN50159 - 1, to search the method to detection the train network equipment.
