摘要
电子接口模块实现了联锁系统(CBI)和计轴系统的全电子化连接,并替代了重力型继电器。电子接口模块与联锁系统的安全完善度等级需达到SIL4级,RSSP-Ⅰ安全协议可按照EN50129标准,对电子接口模块与联锁系统间通信进行完整性、真实性、顺序性和实效性方面的防护,以满足通信的安全要求。
The electronic interface module is designed to realize all-electronic connection of the " ETCS-1"interlocking system (CBI)and the axle counting system and to replace original gravity type relays.The safety grade of the electronic interface module and the interlocking system are required to comply with class SIL4 and RSSP-Ⅰ(Railway Signal Safety Protocol-Ⅰ)protocol shall be conform to the standard of EN50129.Protections for the communications between the electronic interface module and the interlocking system should be attained in terms of integrity, authenticity,sequence and effectiveness,thus ensuring the safety requirements of communications.
