Abstract

The invention discloses a method for synchronizing multi-region data of a comprehensive monitoring system. The method is characterized by comprising the following steps: 1) synchronization region definition, in which, basic information of data servers of a control center, a spare center, a station and a rolling stock depot is defined; 2) cross-linking of ring queue and data service thread, in which, a thread corresponding to the data server is established, and is simultaneously cross linked with the ring queue so as to manage global state information; 3) data extraction and generation and encapsulation of identification information, in which, data to be synchronized is extracted, data description information is established, and the description information and the extracted data are encapsulated; 4) detection and management of server state, in which, the data synchronizing thread detects the state of the server, and updates state information corresponding to the data server in the global state information; 5) data submission and server failure processing; and 6) data submission result identification and data cleaning. The method for synchronizing data of the comprehensive monitoring system can realize high usability, high synchronization speed and high security of data synchronization.

Description

technical field [0001] The invention relates to a method applied to the framework of a rail transit comprehensive monitoring system, capable of synchronizing data in the local area and to other areas, and belongs to the technical field of subway automation. Background technique [0002] With the rapid development of my country's subway automation field and the widespread application of computers, there are various forms of systems in various subway disciplines. These systems have indeed improved work efficiency, but at the same time they have also formed scattered "information islands". Systems that are isolated from each other cannot share data and update data in a timely manner. The comprehensive monitoring system can connect the scattered and isolated automation systems into an organic whole, so as to realize the information exchange and resource sharing among the professional subsystems of the subway; effectively improve the coordination and cooperation ability of each su...
