Abstract

The invention discloses a dual-machine hot standby redundancy implementation system and method for a subway integrated monitoring system. The dual-machine hot standby redundancy implementation systemcomprises a redundancy configuration module, a redundancy network service module, a redundancy message management module and a redundancy core management module. Main and standby self-judgment and main and standby switching of the redundancy management system refer to a strategy that the redundancy management system judges the main and standby states of the redundancy management system according to login information after the redundancy management system is started and carries out main and standby switching according to the safety message information of the host in the system operation process. According to the method, self-judgment of main and standby of the redundancy management system can be achieved, main and standby switching of the managed process is conducted in a targeted mode through information interaction with the redundancy management system, and then hot standby redundancy of the whole subway comprehensive monitoring system is achieved.

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...
