Rail traffic train operating control system based on cloud computing

Abstract

The invention provides a rail traffic train operating control system based on cloud computing. The rail traffic train operating control system comprises cloud computing devices and local train controldevices which are connected through redundant communication networks; the cloud computing devices provide real-time computing and storage services for all the local train control devices, and simultaneously provide the multiple redundant real-time computing and storage services for single-time computing application related to train operation control of the single local train control devices in avirtual isolation or physical isolation mode, and multiple redundant computed results are generated through computing and sent to the local train control devices; and the local train control devices complete the safe input, safe data comparison, train control safe computing control and safe output processing processes, and the safe computed result is obtained from the multiple computed results ina safe comparison mode. The invention provides an implementation method for migrating the computing link to the cloud under the premise of ensuring the safety, credibility and timeliness of a safe computing platform, and the problems of the computing capability and the resource utilization rate of the safe computing platform are solved.

Description

technical field [0001] The invention relates to the technical field of rail transit train operation control, in particular to a rail transit train operation control system based on cloud computing. Background technique [0002] At present, the rail transit system mainly includes railways and urban rail transit (hereinafter referred to as urban rail). In recent years, new rail transit train operation control systems, such as the Chinese Train Control System (CTCS) applied to railways and the Communication Based Train Control System (CBTC) applied to urban rail , emerged as the times require, providing a solid technical foundation and safety foundation for high-speed railways and high-density and low-interval urban rails. [0003] By analyzing the current CTCS and CBTC system structures, it is not difficult to find that these systems follow the idea of ​​traditional signal equipment design, adopt different subsystems for different operation control functions, and realize the ...

AI Technical Summary

Problems solved by technology

[0016] Existing cloud computing services generally request service resources through the Web, and its real-time performance is obviously unacceptable for train control security computing

Especially if there is a network delay or interruption

Cloud computing generally uses remote network access. Although the network speed is increasing rapidly, compared with the local area network, the speed is still delayed. The train control security calculation requires real-time calculation and has high requirements for calculation delay.
