Dynamic redundancy backup method and system suitable for train control system platform

Abstract

The invention provides a dynamic redundancy backup method and system suitable for a train control system platform, and the method comprises the steps: executing a power-on synchronization management flow under the condition that a power-on initialization detection result is qualified, so as to determine main control equipment and a standby host of the train control system platform; on the basis ofthe system configuration information and the configuration information of each board card, respectively determining a mainboard corresponding to the main control equipment and a standby board corresponding to the standby host; loading a host application related to the main control equipment to the mainboard, and loading a standby application related to the host application to the standby board; and controlling the host application and the standby application to operate to enable the train control system platform to enter a dual-computer hot standby operation mode. The invention provides a setof redundant backup processing logic, and the spare board card is dynamically utilized to deploy the backup application, so that the stable and continuous operation of the host and the spare machinecan be ensured, hardware resources are integrated and utilized to the greatest extent, the design requirements on main and spare redundancy are met, and higher safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a dynamic redundancy backup method and system suitable for a train control system platform. Background technique [0002] Most of the current train safety control systems in the field of rail transit are deployed on the train safety computer, and the safety computers on the train are all built on the redundant structure system of the train safety computer platform. The current redundant structure of the train safety computer platform mainly includes: dual-machine hot backup, three out of two, two times out of two out of two, etc., among which two times out of two is the current mainstream redundant architecture of the train safety computing platform. [0003] The functions of the train safety computer are performed by application software, and each application software is deployed on a designated hardware board, and due to the redundant design, there is more than one board t...

AI Technical Summary

Problems solved by technology

[0005] Therefore, there are mainly the following defects in the redundant backup design of the current railway train safety computer: one is that the software and hardware of the main control device and the backup host are all fixed configurations. The second is that when the system is running under the condition of dual-machine hot standby, once the failure of the main control device or the backup host occurs, the system will be in an unsafe state; the third is the dual-system hot backup setting of the main control device and the backup host , will cause a lot of waste of hardware resources; if the hardware resources themselves are relatively tight, it will restrict and limit system applications and functions
