Embodiment Construction

[0074] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0075] The historical data storage system in the industrial control system stores the real-time data in the industrial control system for subsequent process analysis, fault tracing and control scheme improvement. With the enlargement of industrial control systems, the number of signals within the system has multiplied, resulting in a dramatic increase in the number of historical records. In order to ensure the data capacity and operating efficiency of the industrial control system, ...

Abstract

The invention discloses a method and a device for compressing industrial real-time data, which are applied to an industrial control system. The method comprises the following steps of determining a current data point to be stored in the industrial control system, and acquiring a latest stored data point in stored data points in the industrial control system for serving as a target data point; determining a compression time tag of the current data point according to a target time tag in the target data point and a current time tag in the current data point; determining the compression quality code of the current data point according to a target quality code in the target data point and a current quality code in the current data point; determining a compression floating point value in the current data point according to a target floating point value in the target data point and a current floating point value in the current data point; and integrating the compression time tag, the compression quality code and the compression floating point value to obtain a compression data point of the current data point.

Description

technical field [0001] The present application relates to the technical field of industrial real-time data storage, in particular to an industrial real-time data compression method and device. Background technique [0002] The historical data storage system is provided in the industrial control system to save the real-time data on site for subsequent process analysis, fault tracing and control scheme improvement. With the enlargement of industrial control systems, the number of signals within the system has multiplied, resulting in a dramatic increase in the number of historical records. In order to ensure the data capacity and operating efficiency of the industrial control system, it is necessary to compress and store these historical real-time data. [0003] Among them, industrial real-time data is stored in the form of data points, and each data point consists of a time tag, quality code and value. The time tag is the collected time value of the data point, in milliseco...
