Problems solved by technology

[0009] When querying all the data of device A in a certain time period (time i to time j) to make a data report, it is necessary to load the entire file and judge the interval position from time i to time j one by one. When the data file is large, the retrieval efficiency very low

Embodiment Construction

[0033] A method for storing and retrieving real-time monitoring data of equipment with large data volume, comprising the following steps:

[0034] Store the data files in the secondary directory by year and month; both the index file and the data file are binary files with different extensions, and they all follow the same naming rules, that is, the file name contains the year, month, day, and time identifiers, and the year The month-day-time identifier is used for primary retrieval of index files and data files;

[0035] In the process of real-time recording of monitoring information, an index file and data file are generated every day;

[0036] The index file is divided into two parts, the first part is the index directory, and the second part is the periodic data index;

[0037] The index directory records the address location information of the data index at the beginning of each minute, as shown in Table 2. If the daily single data file is less than 4GB, the address loca...

Abstract

A method for storing and retrieving real-time monitored data of large-volume equipment comprises storing data files in a second-level directory according to year and month; and generating one index file and data file everyday while real-timely recording monitored information, wherein the index file includes an index contents and a periodic data index; and the periodic data index is used for recording the specific position address and the data length of various types of information in the data file in each collection period, and the number of bytes is increased or reduced according to the actual condition to realize the optimal use effect. When a user inputs a query term and selects the equipment type to be queried, the data type, the start time t1 and the stop time t2, all information values meeting the query term can be retrieved from the current data file by single matching and calculation. The invention provides a method for storing and retrieving real-time monitored data of large-volume equipment.

Description

【Technical field】 [0001] The invention relates to a method for storing and retrieving real-time monitoring data of equipment with a large amount of data, in particular to a file storage and efficient data retrieval method for real-time monitoring data based on a specific protocol. 【Background technique】 [0002] The file database is also called an embedded database, which saves the content of the entire database in a single index file to facilitate the publication of the database. And traditional databases (such as: DB2, Oracle, SQL server, etc.) data are stored in different ways. The traditional database needs to be accessed through some database engines. Since the file database is stored in a single file, the deployment and release of the database are relatively simple, and it is suitable for embedding in the application. When the amount of data is not too large, the speed is faster than the traditional database. [0003] Text-type data files have the characteristics of ...
