摘要
列车超速防护系统(ATP)是城市轨道交通和高速列车运行时必不可少的安全保障,必须满足故障—安全特性,因而其中的核心部分微计算机系统必须具有高安全性。采用硬件、软件冗余技术与安全输出通道,可极大地提高计算机系统的安全性能。
ATP is the indispensable device of high speed train and trolley so that they could run safely, it must accord with fault safety principle.It's micro-computer must be highly safe. To appropriate hardware and software redundance technology and safety chunnel could improve the security of computer system.
