In-stockroom operation method and device of electric power measurement acquisition system

Abstract

The invention discloses an in-stockroom operation method of an electric power measurement acquisition system. The in-stockroom operation method includes the steps of building a distributed cache system between the electric power measurement acquisition system and a database server, sending measurement data acquired by the electric power measurement acquisition system to each cache node of the distributed cache system, judging whether a cache period of each cache node expires or not, and sending the measurement data in the cache nodes with the expired cache periods to the database server. In addition, the invention further discloses an in-stockroom operation device of the electric power measurement acquisition system. By means of the in-stockroom operation method and device, complexity caused by matter mechanisms of the measurement data in the in-stockroom process is reduced, the in-stockroom operation performance and the in-stockroom efficiency are improved, and the terminal capacity capable of being supported by the electric power measurement acquisition system is improved. The distributed cache system in the in-stockroom operation method further has the dynamic propagation capacity, supports can be provided for large-capacity in-stockroom tasks of measurement data, and the in-stockroom performance is further improved.

Description

technical field [0001] The present invention relates to the technical field of electric power metering and collection systems, and in particular to a storage operation method of the electric power measurement collection system and a storage operation device of the electric power measurement collection system. Background technique [0002] As an important automated power system, the power metering and acquisition system is very complex. It integrates multiple functions and links such as the master station system, acquisition terminal, electric energy meter, and auxiliary equipment system. For the power metering collection system, whether the metering data can be efficiently pushed into the database after the metering terminal collects the metering data plays an important role. At present, after the power metering collection system collects the metering data, it usually directly writes the metering data collected in real time into the relational database server. Because the s...

Problems solved by technology

Because the storage operation is not only limited by the I / O performance of the hard disk, but also the relational database introduces a transaction mechanism to ensure data consistency, resulting in low storage operation efficiency

When the number of collection terminals in the collection system increases, the storage operation becomes the performance bottleneck of the system, and a single relational database often cannot meet the requirements

And if you want to build a database cluster, the cost will be greatly increased
