The invention discloses a vehicle-mounted safety computer system which achieves complete double-end redundancy of two sets of vehicle-mounted safety computers on a train, when one set of vehicle-mounted safety computer breaks down, the other set of vehicle-mounted safety computer can continue to maintain normal operation of the train, and the reliability and usability of the system are effectivelyimproved. According to the technical scheme, a complete double-end redundancy design is adopted, that is, a set of vehicle-mounted safety computer with a 2 * 2-out-of-two architecture is arranged ateach end. In addition, the host of the vehicle-mounted safety computer at each end of the train has redundancy design, I/O has redundancy design, and the two sets of vehicle-mounted safety computers at the two ends have redundancy design. When one system of the vehicle-mounted safety computer breaks down, the other system can continue to maintain normal operation of the train; when one set of vehicle-mounted safety computer breaks down, the other set of vehicle-mounted safety computer can continue to maintain normal operation of the train; only when the redundancy design fails or fails, the remaining last system can guarantee safe parking, and therefore the reliability and usability of the system are effectively improved.

    本发明公开了车载安全计算机系统,实现列车上两套车载安全计算机完全双端冗余,当其中一套车载安全计算机故障时,另一套还可以继续维持列车正常运行,有效提高系统可靠性和可用性。其技术方案为:本发明采用完全双端冗余设计,即每端设置一套2乘2取2架构的车载安全计算机。此外,列车每端的车载安全计算机的主机有冗余设计、I/O有冗余设计,两端的两套车载安全计算机又为冗余设计。当车载安全计算机的一系故障时,可由另一系继续维持列车正常运行;当其中一套车载安全计算机故障时,另一套车载安全计算机还可以继续维持列车正常运行;只有当冗余设计都故障或失效时,剩余的最后一系能够保证安全停车,从而有效提高系统可靠性和可用性。
