Problems solved by technology

[0004] In the industrial automation monitoring system, the traditional historical data archiving method is to process the above data separately. For example, the archive library is divided into analog gauges, digital gauges, alarm tables, log tables, etc., and the correlation between various types of data is poor. , are basically independent parts and do not have the ability of correlation analysis and processing

Abstract

The invention discloses a holographic process data archiving and inverting method based on a dynamic change frame, which is used for carrying out the holographic compression record and the holographic inversion on the change process of the process data. According to the characteristics of the process data, the invention provides the archiving and retrieving method which takes the time as a reference and the dynamic change frame for aggregating a variety of process data as an archiving object and adopts multistage compression processing, thereby effectively reducing the occupancy rate of the process data archiving space, improving the retrieval efficiency of the archived data, and providing a basis for the holographic inversion in a way of storing by aggregating a variety of process data. Due to the adoption of the method, the practicability and the usability of the historical data in an industrial automation system are effectively improved, and the uniform processing of a variety of process data makes the historical holographic inverting process possible.

Description

technical field [0001] The invention belongs to the field of real-time databases of industrial automation systems and is applied in real-time monitoring systems of industrial automation systems. The method is applied to the holographic data recording and retrieval of process data in real-time databases, and adopts a method of dynamically changing frame recording to process data. The change process of holographic recording and holographic inversion. technical background [0002] In the industrial automation monitoring system, the real-time database provides data support for various application fields. In addition to providing real-time data collection and real-time data of industrial automation monitoring objects, the real-time database usually also needs to provide efficient retrieval functions for massive process data. [0003] The content of the process data usually includes: the change trend of the collected quantity, alarm information, and operation log information. [...
