Abstract

This application provides a large-scale charging pile data processing method and device for electric vehicle charging network, which is applied to the server, including: receiving the charging pile data sent by the charging pile; according to the first attribute value corresponding to the preset key field, Determine the database storage node corresponding to the charging pile data; perform a hash operation on the second attribute value corresponding to the preset distribution key field to obtain the hash value corresponding to the charging pile data; determine the charging pile data according to the hash value corresponding to the charging pile data The target storage area of ​​the pile data in the database storage node; store the charging pile data in the corresponding target storage area. By selecting the key fields and distribution key fields of the charging pile data, the target storage area of ​​the charging pile data in the database storage node can be located, and any field information of the charging pile data can be flexibly read and processed without the need for the user to perform conversion configuration, operation It has low complexity and high flexibility, and is suitable for scenarios where certain attribute fields are frequently updated.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular, to a data processing method and device for large-scale charging piles in an electric vehicle charging network. Background technique [0002] The real-time data of charging piles includes real-time status, real-time interaction and other information of charging piles, which is one of the important information to understand the operation of electric vehicle charging network. However, the scale of charging piles is large, there is a lot of real-time status information, and the update frequency is high. Traditional relational database storage cannot store charging pile data. [0003] At present, a method of storing charging pile data using json string storage is provided. The specific storage process is as follows: use the simplest key-value method, select the charging pile number of the charging pile data as the key for storage, and store the charging pile All other...
