对轨道交通信号安全系统的2×2取2平台和3取 2平台以及2×2取2平台的不同实现方式进行了比选,明确了以2×2取2平台作为研究重点。提出了2×2取2平台的基本构架,论述了实现双套相异算法的并行计算流程, 并对具体实现中的几个关键问题进行了讨论。
The different implementations of 2 × 2 and 2 platforms and 3 and 2 platforms and 2 × 2 and 2 platforms of the rail transit signal security system were compared and selected. The 2 × 2 platform was taken as the research focus. The basic framework of 2 × 2 and 2 platforms is proposed. The parallel computing process of realizing two sets of dissimilar algorithms is discussed. Several key problems in the concrete implementation are also discussed.
