基于内生安全的轨道交通控制系统研究OA

Rail signal control networks are characterized by their mutual independence,therefore,thorough consideration must be given to their network information security protection.The research method of a rail control system based on endogenous security is presented.The kernel bypass mechanism is utilized for data acquisition to add an independent network board in the control system for data reporting and configuration management by the built-in security monitoring components.At the same time,based on the design principle of function separation,and using the kernel bypass method,the technical architecture of"one core+three major subsystems"is designed for the security monitoring components,the control system subsystem with built-in security monitoring function,the upper computer subsystem with built-in security monitoring function,and the comprehensive security monitoring and analysis subsystem,so as to achieve the fundamental enhancement of the information security of the rail control system.
