Abstract

The invention provides a sensor timing-sequence data storage method and system with a hierarchical structure. The method includes the following steps that when acquisition data of a sensor is obtained, the attribute information of the sensor and the description information of the acquired data are obtained at the same time; the attribute information serves as a first storage path byte, and the description information serves as a second storage path byte; the first storage path byte and the second storage path byte are combined to form a data storage path, and the acquired data is stored in thedata storage path. The attribute information of timing-sequence data is arranged in order and combined with the description information of the timing-sequence data to form the data storage path, a wildcard-character matching mode is introduced for semantic enhancement, a full path describing the unique path of the sensor can be expressed, prefix paths of several sensors and a with-star path describing several hierarchical combinations are described, the attributes of the sensors can be clearly and fully expressed, and the hierarchy correlation between the attribute information can be clearlyshown.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more particularly, to a method and system for storing time series data of sensors with a hierarchical structure. Background technique [0002] The full name of time series database is time series database. Time series databases are mainly used to process data with time tags (changes in the order of time, that is, time serialization). Data with time tags is also called time series data. Time series data is mainly collected and generated by various types of real-time monitoring, inspection and analysis equipment in the power industry, chemical industry, etc. The typical characteristics of these industrial data are: fast generation frequency (each monitoring point can generate multiple pieces of data), heavily dependent on the collection time (each piece of data requires a unique time), and a large amount of information at the measurement points (conventional real-time monitorin...
