BMS data storage system and method based on database

Abstract

The invention discloses a BMS data storage system and method based on a database. The system comprises a data collection module, a data classification module, a storage rule module, a basic table module and a fact table module. The data collection module is used for collecting data from all target sources, the data classification module is used for receiving the data and dividing the received data into different categories, the storage rule module is used for storing storage rule information corresponding to the data of all the categories and storage rule indexing information, the basic table module is used for storing the data of the different categories in a classified mode, and the fact table module is used for storing the storage states and storage position information of the data of the different categories. The BMS data collected on site are stored in a novel storage mode, and classified storage, reliable management, safety backup and other operation on the BMS data are completed by means of the powerful data processing tool (the database).

Description

technical field [0001] The invention relates to the field of battery management systems (BMS), in particular to a database-based BMS data storage system and a method thereof. Background technique [0002] The on-site personnel store the BMS operation data and historical fault data in the computer through the host computer software in the form of files. After a large amount of data collection, the stored files are scattered in the computers of each on-site personnel. Manually sent by e-mail, etc., and the above scattered collected data may not be sorted and stored. Once lost, it is necessary to go to the field to collect data again. When it is necessary to analyze field data to solve problems or conduct data analysis and research It will be difficult to realize the data collection, and it is likely that relevant personnel will be required to collect data on site, which will reduce efficiency virtually. The collected BMS data cannot be categorized and archived, which is not c...

[0002] The on-site personnel store the BMS operation data and historical fault data in the computer through the host computer software in the form of files. After a large amount of data collection, the stored files are scattered in the computers of each on-site personnel. Manually sent by e-mail, etc., and the above-mentioned scattered collected data may not be sorted and stored. Once lost, it is necessary to go to the field to collect data again. When it is necessary to analyze field data to solve problems or conduct data analysis and research It will be difficult to carry out data collection, and it is likely that relevant personnel will be required to collect data on site, which will reduce efficiency virtually.

The collected BMS data cannot be categorized and archived, which is not conducive to subsequent research work, and often the data cannot be perfectly preserved. If the stored data is needed in the future, it is difficult to find it from a large amount of data
