The present invention provides a method for realizing multi-machine master / standby of a power quality management system. S1 and the main control module process run, and synchronously create a server heartbeat message timing service and a server information monitoring timing service, and the server information monitoring timing period is greater than or equal to 2 The server heartbeat timing cycle; S2, create a synchronizer thread; realize the synchronous communication of communication messages among multiple machines through the synchronizer; S3, register the multicast service; S4, initialize the data structure of the local server information pool; after obtaining the server heartbeat message , to update the content in the corresponding server record in the message data. In the embodiment of the present invention, aiming at problems that are likely to occur in the application site of the power quality management system, the above-mentioned method is adopted to enhance the redundancy of the power quality management system, improve the robustness of the system, and achieve the expected effect in the deployed site.
Description
technical field [0001] The invention belongs to the field of multi-computer active backup of power quality management system, and in particular relates to a method for realizing multi-machine active backup of electric energy quality management system. Background technique [0002] The power quality management system mainly includes acquisition module, calculation and analysis module, storage module and display module. Each module completes the follow-up work of the previous module in turn. Each module complements each other to realize the function of the power quality management system. When there is a problem in any link of any module, it will cause the subsequent modules in the power quality management system to fail to work normally, affecting the normal use of the power quality management system. The application field of power quality management system is more and more extensive, and it has gradually received attention and attention. The stability of the power quality m...
