摘　　要：为适应铁路系统分布式控制以及铁路设备数字化、智能化的发展方向,文章提出一种基于RAFT算法适用于分布式安全计算机云平台系统的共识机制方法。该安全计算机云平台通过光纤的方式与不同应用的铁路信号系统设备和室外控制设备相连接,可以同时运行不同功能的系统,能够有效地减少分立的安全计算机平台的数量,降低成本,缩减施工周期,方便扩展。同时,根据铁路信号安全平台的特点和需求,研究基于RAFT算法的共识机制实现流程,并以典型的铁路信号联锁系统为例设计详细的实现方法,最后针对算法实现过程中的安全性设计进行改进,并验证其可靠性。In order to adapt to the development trend of distributed control of railway system and digital and intelligent railway equipment,a consensus mechanism method based on RAFT algorithm for distributed security computer cloud platform system is proposed in this paper.The secure computer cloud platform is connected with railway signal system equipment and outdoor control equipment of different applications by means of optical fiber,and can run systems with different functions at the same time,which can effectively reduce the number of separate secure computer platforms,reduce costs,shorten the construction cycle,and facilitate expansion.At the same time,according to the characteristics and requirements of railway signal security platform,the implementation process of consensus mechanism based on RAFT algorithm is studied,and a detailed implementation method is designed by taking a typical railway signal interlocking system as an example.Finally,the security design of the algorithm is improved and its reliability is verified.
