System and method for implementing dual-machine hot standby redundancy for integrated subway monitoring system

Abstract

The invention discloses a dual-computer hot standby redundancy implementation system and method for a comprehensive subway monitoring system, including: a redundant configuration module, a redundant network service module, a redundant message management module and a redundant core management module; The self-judgment of active and standby of the redundant management system and the active and standby switching of the invention refer to the strategy of judging the active and standby state according to the login information after the redundant management system itself is started, and performing the active and standby switching according to the host safety message information during the operation of the system . The present invention can realize the self-judgment of the master and backup of the redundant management system, through the information interaction with the redundant management system, the master and backup switching of the managed process can be targeted, and then the hot backup redundancy of the entire subway comprehensive monitoring system can be realized.

Description

technical field [0001] The invention belongs to the technical field of data redundancy management, and in particular relates to a dual-computer hot standby redundancy realization system and method for a comprehensive subway monitoring system. Background technique [0002] The comprehensive subway monitoring system is a large-scale automatic monitoring system for the urban rail transit industry. The system usually adopts advanced computer technology and communication technology, and shares a unified dispatching and commanding master station platform in accordance with the principles of unified planning, decentralized monitoring, and hierarchical layout. Realize automatic monitoring function. [0003] The integrated monitoring system is deployed on two physically equivalent real-time servers, and the two servers establish a stable Ethernet transmission connection through an industrial-grade integrated monitoring redundant switch. The background services of the comprehensive m...
