Abstract

The invention discloses a server multi-center real-time hot backup switching device of an automatic train monitoring system, which improves the reliability of the central server. The technical solution is: the device includes: at least one central server to realize the function of the automatic train monitoring system; at least one server data cluster component is respectively deployed on each central server, and communication between the server data cluster components is established to form a server data cluster , there is one primary server data cluster component and at least one standby server data cluster component in the server data cluster, the central server communicates with the primary server data cluster component, stores and obtains data through the primary server data cluster component, and all the server data clusters The component saves a data copy and keeps the data copy synchronized. When the main server data cluster component fails, it is upgraded from a standby server data cluster component to a new main server data cluster component.

Description

technical field [0001] The invention relates to a server hot standby switching technology, in particular to a multi-center real-time hot standby switching device for an application server of an ATS (Automatic Train Supervision) automatic train monitoring system applied in an urban rail transit signal system. Background technique [0002] At present, during the operation of rail transit, the monitoring and control of the train is very important, so many reliability designs have been carried out in the development process of the rail transit signaling system. In the urban rail transit signaling system, the ATS system, as the supervision and control terminal of the signal, is the most direct and convenient operation tool for the dispatcher, and its importance is self-evident. At present, most ATS products in China only adopt the redundant deployment strategy of OCC dual hosts (active and standby). The so-called dual host redundancy strategy, such as figure 1 As shown, there ar...
