Electric energy quality management system multi-machine database synchronization realization method

The invention provides an electric energy quality management system multi-machine database synchronization realization method, comprising the following steps: S1, setting a plurality of servers, allowing each server to run the same set of electric energy quality management system software, and using a main control module in an electric energy quality management system to monitor the state of eachserver; and S2, dividing server roles into a host and a standby, running the process of the main control module, monitoring role changes among the servers, and controlling the servers to perform roleswitching work. According to the system, the data files of the sqlite type can be written into the database conveniently for data synchronous transmission. A large amount of communication message analysis work and frequent data writing are avoided, the database does not need to be subjected to any role transformation operation, the roles of the databases running in all servers are consistent, database problems are further
