A load balancing method for cross-regional data exchange in rail transit comprehensive monitoring system

Abstract

The invention discloses a load balancing realization method for cross-regional data exchange of a rail transit comprehensive monitoring system. It divides the system into different regional groups according to the center and station, and numbers them in numerical order. Each group is composed of several application nodes, and the application nodes are divided into two types: application master and application backup; The inter-group message forwarding module is run on the application nodes; the station group host establishes a communication link with the Nth application node of the central group (N=station group ID% the number of central application nodes), and the inter-group message forwarding module of the station is configured according to the predefined configuration Distribute the corresponding data to the Nth node of the center (it can be configured to be forwarded to any group, not limited to forwarding to the center). After the data processing of the central standby machine is completed, the data is synchronized to the application host through the local message transmission module to ensure that the application host Integrity of node data.

Description

Technical field [0001] The present invention relates to load balancing implementation methods cross-regional data exchange cross-regional data exchange, belonging to the field of rail transit integrated monitoring system. Background technique [0002] Rail Transport Integrated Monitoring System (hereinafter referred to as ISCS) is a typical industrial control distributed system. It consists of a control center and a number of stations in different geographical nodes. By integrating SCADA, BAS, PIS, CCTV and other professional systems from different regions, realizing resource sharing, professional integration, in a unified platform Monitoring of each subsystem. [0003] In the Comprehensive Monitoring System Control Center (hereinafter referred to as the center) - the station system structure, the center has its own server, and the center often has multiple servers, and the station generally configures 2 servers. Varian systems are stored from the center and station access system...

AI Technical Summary

Problems solved by technology

[0004] Since the center needs the data of all stations, with the increase of station sites and the increase of integrated professional systems of each station, the central server has no time to process the data forwarded by each station, and problems such as delay or even data loss will occur. Currently, although the control center There are multiple servers, but because the comprehensive monitoring system is generally on duty for the whole machine or by professional duty, in fact, only the server running the business host performs data processing, so the above problems cannot be solved by using multiple servers in the center
