Further, at zero point every day, the lower end data acquisition module 5 reads the telemetering information of the previous day from the redis data storage module on time and writes the telemetering information into the mongoDB data storage module and the mysql data storage module, and the ETL data processing module carries out statistical analysis on the historical information on time and stores the statistical analysis results into the mongoDB data storage module and the mysql data storage module.
The invention effectively solves the problem that the real-time operation data of the meter acquired by the data acquisition equipment can not be stored in the database of the server when the network communication between the data acquisition equipment and the server fails, and avoids the phenomenon of data loss caused by network communication failure; the user can customize a corresponding alarm rule according to the own requirement, and the alarm function meeting the requirement of the user is realized; and by optimizing the data analysis function, the system is only provided with simple data statistics function of year, month and day, the functions of data comparison analysis and comparation analysis are added, various defects of the current power distribution room on-site monitoring system are overcome, and the functions of the power distribution room on-site monitoring system are comprehensively improved.
Although the invention has been illustrated and described in detail by means of preferred embodiments, the invention is not limited to the disclosed examples and other variants can be derived therefrom by the person skilled in the art without departing from the scope of protection of the invention.
