Problems solved by technology
[0003] There are many historical values of online monitoring data, and the data reading and analysis requirements of the same monitoring device are high. The use of power automation, monitoring system conventional batch data point fixed time interval or single data point single table and other historical data caching methods consumes storage space Large, access to the monitoring data values at a specific historical moment of the same monitoring device needs to access multiple data tables to obtain the required data access efficiency and other issues
[0004] Therefore, a method is provided to solve the problem of large storage space consumption in the historical data caching method currently used in the field of online monitoring of electric power equipment, accessing the monitoring data values at a specific historical moment of the same monitoring device requires accessing multiple data tables to obtain the required data Low access efficiency and other technical issues

The embodiment of the invention discloses a storage and access method for an on-line monitoring data historical value. Analogue type and digital type state moment values obtained in a way that an on-line monitoring device collects target electrical equipment are independently processed, the digital type state moment value of one group of target electrical equipment is stored at aero o'clock everyday by aiming at the characteristic of low change speed of the digital type online monitoring data, a digital type state moment value change record is combined to reckon the target digital type state moment value and the target analogue type state moment value of a user requirement moment, storage space can be saved, a data storage position can be quickly determined, and query efficiency is improved. The embodiment of the invention also provides a storage and access device for the on-line monitoring data historical value.
Description
technical field [0001] The invention relates to the field of on-line monitoring of electric equipment, in particular to a method for storing and accessing historical values of on-line monitoring data. Background technique [0002] The on-line monitoring system for the status of power transmission and transformation equipment will generate a large amount of measurement data during operation, that is, various data collected by sensors to monitor the operation of power equipment. These data are transmitted to the main station system of the power transmission and transformation equipment status monitoring system through the remote acquisition and processing unit, and displayed as real-time history, and can be viewed by dispatching, monitoring, and maintenance personnel of the power supply network to judge the operation status of the equipment and carry out equipment management accordingly (such as test, maintenance, etc.) operation. When the real-time data is displayed on the...
