A data synchronization method for urban rail transit security system

Abstract

This application discloses a data synchronization method for an urban rail transit security system. The database of the site main control platform receives and stores the first data in the corresponding site-level platform security data; the first data in the database of the site main control platform is monitored changes in the situation, filter the first data to obtain the data to be synchronized, and send the data to be synchronized to the databases of other platforms; the databases of the other platforms receive the data to be synchronized and perform incremental processing, so that The data is kept synchronized with the database of the site master control platform; any level of platform can grasp the synchronized security event data when taking over a certain site, thereby improving the flexibility of security event handling.

Description

technical field [0001] The invention belongs to the field of security technologies, in particular to a data synchronization method for urban rail transit security systems. Background technique [0002] At present, the security system of urban rail transit generally adopts two-level management at the center level and the station level. It has a hierarchical distributed structure with three levels of control at the road network center level, line center level, and station level. Specifically, it is as follows: figure 1 as shown, figure 1 It is a schematic diagram of the existing traffic security system architecture. [0003] Among them, the site-level platform can capture various types of alarm events that occur in the site at the first time, and perform corresponding processing according to the type of alarm event, while the center-level platform (line center level and road network center level) wants to continuously track the development of events and disposal process, the...

Problems solved by technology

[0003] Among them, the site-level platform can capture various types of alarm events that occur in the site at the first time, and perform corresponding processing according to the type of alarm event, while the center-level platform (line center level and road network center level) wants to continuously track the development of events and disposal process, the database of the site-level platform needs to report security incidents layer by layer, which makes the central platform unable to respond quickly and timely to security incidents, and once an emergency occurs on one of the platforms and makes it unavailable, The platform that takes over the security protection cannot obtain the security event information and data returned by the field equipment. For example, when the line-level application server fails, the security event data of the site-level application server connected to it cannot be transmitted to the In the center-level application server, the central-level application server cannot handle the security incidents of these sites in a timely and effective manner, thus reducing the flexibility of security incident handling
