摘要
城轨交通信号系统数字化转型已成为趋势,信号系统在和云平台的结合过程中,除了考虑两者之间的适配,更关键的是要证明云平台RAM指标满足信号系统要求。比较了传统ATS系统和云平台ATS系统的结构;以某一主流云平台为例,研究了云平台硬件设备及软件的RAM指标能够满足信号系统ATS上云的要求;所使用的云平台工具和方法,对信号系统安全评估具有良好的参考价值。
Digital transformation of signal system in urban rail transit has become a trend.For the combination of signal system and cloud platform,it is more critical to prove that the RAM index of the cloud platform meets the requirements of the signal system in addition to considering the adaptation between the signal system and the cloud platform.The structure of the traditional ATS and that of the ATS system based on a cloud platform is compared.Taking a mainstream cloud platform as an example,it is studied that the RAM index of hardware equipment and software of the cloud platform can meet the requirements to build the ATS over the cloud platform.The cloud platform tools and methods adopted in the study have good reference value for safety evaluation of the signal system.
