Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0037] A preferred embodiment of the present invention relates to a method for storing and indexing industrial data based on time series. The industrial data in this embodiment comes from different collection points, and each piece of industrial data contains a time stamp. When storing, store industrial data within a period of time in a data file to ensure that each data file is uniquely corresponding to a period of time, and that the periods corresponding to each data file are continuous. A data file further includes multiple physical blocks. The data file is divided into two parts, the main data area and the overflow data area, and at least one physical block is allocated to each collection point in the main data area and the overflow...

Abstract

The invention discloses an industrial data storage and index method based on time series, which is used for storing industrial data in the same time slot into a data file and storing data belonging to the same acquisition point into the same physical block, so as to avoid the trouble of storing tags of acquisition points corresponding to all industrial data, save the storage space and remarkably improve the data storage efficiency in case of tens of thousands of industrial data in the industrial field. During inquiry, the corresponding data file is indexed according to the time slot of the industrial data to be inquired, the corresponding initial physical block is indexed according to the tag of the acquisition point to be inquired, and the physical storage location of the industrial datain the time slot required to be inquired according to the beginning and the end time in the initial physical block and the pointer of the next physical block. By adopting the method, the industrial data in a time slot can be quickly indexed and inquired in large batches, so that the inquiry requirements of industrial data can be satisfied.

Description

technical field [0001] The invention relates to the field of database storage and indexing, in particular to industrial data storage and indexing technology. Background technique [0002] Industrial data comes from industrial production or related data. An industrial data corresponds to a physical point in production, such as the cumulative output of a certain production line, the temperature of a certain detection point, etc. Industrial data is a continuous amount, and the stored data has a time stamp. Industrial data has obvious time characteristics, and its structure can be represented by VQT (Value, Quality, Timestamp, data value, quality code, time stamp). At the same time, industrial data is continuously generated and has the characteristics of massive data. [0003] Existing database technology has well solved the storage and access requirements of relational data. But for industrial data, the existing storage and access methods have many deficiencies. [0004] Du...
