Problems solved by technology

[0005] Aiming at the technical problems in the prior art that record and store historical data in a self-defined text structure that stores data with a fixed number of bytes and a relatively limited format, it is easy to cause loss of historical data, and it is not convenient to automatically change the report export format according to the type of equipment. The present invention Provides a data management method and device based on an Android database, which realizes flexible recording and storage of historical data, reduces the probability of data loss caused by reading and writing errors, and can avoid problems caused by existing custom text structure upgrades and upgrades. The phenomenon of historical data loss, and the corresponding data report can be automatically exported according to the type of equipment, which improves the user experience

Abstract

The invention discloses an Android database-based data management method and device, and belongs to the technical field of data storage, search and export. The data management method comprises the following steps: S1, determining a data storage scheme according to the current version of an Android database and a software version of the current database management system, and storing the historical data of electronic equipment in the Android database on the basis of the data storage scheme; and S2, searching the Android database according to the equipment type of the current electronic equipment, and exporting the searched historical data corresponding to the equipment type of the current electronic equipment in an EXCEL document form. According to the method and device, the historical data can be flexibly recorded and stored, the data loss probability caused by read-write errors is reduced, the historical data loss phenomenon caused by upgrading and downgrading of self-defined text structures can be avoided, and corresponding data statements can be exported according to the equipment types, so that the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of data storage, retrieval and export, in particular to a data management method and device based on an Android database. Background technique [0002] With the rapid development of the electrical automation industry, electronic equipment is distributed in all walks of life. For some electronic equipment used in system operation monitoring, its operating data directly reflects the operating status of the system. Therefore, the historical data of these electronic equipment is analyzed. Recording, storage, export and analysis are helpful for staff to clearly understand the operating status of the system. For example, in the power electronics industry, for power quality products, such as active filters (APF), static var generators (SVG), enhanced static var generators (ASVG), etc., it is necessary to record their near The operation data of two years can be exported to EXCEL report when needed to analyze the op...
