摘要
根据西安地铁 14 号线研究对承载信号业务的LTE系统增加 3 级等级保护的具体方案及步骤,针对 14 号线线路特点提出 2 个可行的等级保护接入方案,并通过网络架构及性能评估比较,选择最优的等保接入方案,确保网络传输的安全稳定.同时通过等保系统相关接口配置、注意事项等描述,详细阐述涉及行车安全的LTE系统在增加等级保护过程中的重要步骤,确保网络安全,为轨道交通信号系统的行车指挥和列车运行控制提供重要保证,为后续轨道交通等保接入提供可参考价值.
Abstract
This paper studies the specific schemes and steps of adding three grades of protection to LTE system carrying signal services based on Xi'an Metro Line 14.Two feasible access schemes of grading protection are proposed according to the characteristics of Line 14,and the optimal grading protection access scheme is selected through network architecture and performance evaluation and comparison to ensure the security and stability of network transmission.At the same time,through the description of the relevant interface configuration and precautions of the grading protection system,the important steps in the process of adding grading protection to LTE system involving the safety of train operation are elaborated to ensure network security,provide important guarantee for traffic control of rail transit signaling system,and provide reference value for subsequent rail transit grading protection access.
