摘要:

轨道交通安全计算机是负责轨道交通安全的核心设备,其安全等级必须达到SIL4。针对该特性,比较三取二结构与二乘二取二结构的特点,基于ReWorks嵌入式实时操作系统,设计并实现三取二结构的安全计算机,并对其中间件进行分析与探讨。该安全计算机已应用于某轨道交通项目,实际应用效果良好。

关键词: 安全计算机, 三取二结构, 轨道交通

Abstract:

The safety computer of railway transportation is the key equipment in charge of safety of railway transportation. Its safety level must be the Safety Integrty Level 4(SIL4). This paper compares characteristics of 2 out of 3 structure and double 2-vote-2 structure, designs 2 out of 3 safety computer based on ReWorks embedded operating system, and studies its middleware. It is applied in railway transportation project, and gets good practical effect.

Key words: safety computer, 2 out of 3, railway transportation
