Embodiment
[0045] In this embodiment, a linkage service system applied to a rail transit comprehensive monitoring system, such as figure 1 As shown, it includes configuration database 1, linkage client 4, linkage server 2 and control server 3. The configuration database and linkage client are respectively connected to the linkage server, and the linkage server is connected to the control server.
[0046] Configuration database: stores linkage schemes and provides linkage configuration information. Linkage is a collection of self-organized functions in parallel. Functions are a collection of actions in series and parallel. Actions are control operations including preconditions and postconditions; configuration Information includes preconditions and postconditions for linkages, functions, and actions. Configuration information includes pre-conditions and post-conditions for linkage, functions, and actions; pre-conditions are used to judge the adjustment of linkage, function, and action exe...

The invention relates to a linkage service system and a linkage service method applied in an integrated rail transit supervisory control system, aiming at solving the problem that the linkage of the existing integrated rail transit supervisory control system is fixed, so that monitoring software needs to be replaced during modification. The system comprises a configuration database, a linkage client-side, a linkage server-side and a control server-side, wherein the configuration database and the linkage client-side are respectively connected with the linkage server-side; the linkage server-side is connected with the control server-side. The linkage service method comprises the steps of triggering linkage, function and action according to whether a precondition and a post-condition are met or not. The system and the method have the advantages that the linkage scheme can be flexibly collocated, and sustainable storage of the database is realized, so that linkage execution results can be stored under the special conditions that the linkage service collapses, restarts and the like, and an operator can conveniently master the linkage execution condition and prejudge the execution of the next step action; the linkage service system is capable of updating in an online way.
Description
technical field [0001] The invention relates to the field of rail transit information processing, in particular to a linkage service system and method applied to a rail transit comprehensive monitoring system with flexible configuration, online update, and status monitoring. Background technique [0002] In the traditional rail transit comprehensive monitoring system, the linkage generally fixes several linkage schemes when the system is built. If the linkage scheme needs to be modified later, the monitoring software needs to be replaced to achieve it. For example, the application number is 200410017772.2, and the name is a Chinese invention application for an integrated monitoring system and its linkage control method. The system includes several detection and alarm systems, an alarm event collection module and a linkage control processing module. For various types of alarm information sent by the alarm system, the linkage control processing module adopts corresponding cont...
