Explosive type data caching and processing system for SCADA system and method thereof

Abstract

The invention discloses an explosive type data caching and processing system for a SCADA system and a method of the explosive type data caching and processing system for the SCADA system. The system comprises a data receiving module, a file caching module, a data pre-reading module, an queue caching module, a data optimization module and a tread pool module, wherein the data receiving module receives a data storage request message sent by an application program and enables the data storage request message to be placed into a disk caching file or a caching queue of the file caching module according to a caching queue state, the data pre-reading module inserts a data storage request stored in the file caching module into the caching queue, the data optimization module reads the data storage request, optimizes the data storage request and then calls an idle thread in a thread pool to execute the data storage operation. The system and method can well solve the safety problem of data and the SCADA system when the massive data storage requests are submitted.

Description

technical field [0001] The invention relates to a data cache processing system, in particular to an explosive data cache processing system oriented to a SCADA system, and also relates to a method for the system to realize explosive data cache processing, belonging to the technical field of data processing. Background technique [0002] SCADA (Data Acquisition and Supervisory Control) system is a computer-based production process control and scheduling automation system, widely used in electric power, metallurgy, petroleum, chemical and other industries. As the scale of the SCADA system continues to increase, more and more content and data need to be monitored, and the SCADA system is constantly facing the test of massive data processing. [0003] In recent years, with the rapid development of computer and network technology, a large number of computer and network technologies have been applied to SCADA systems, making the application functions of SCADA systems more and more ...

AI Technical Summary

Problems solved by technology

[0005] First, because the explosive data storage request will gather massive data in a short period of time, waiting to submit the database in the memory may cause memory overflow, resulting in the loss of a large amount of important data

What's more, it will cause the entire SCADA system to collapse directly, and the consequences will be disastrous

[0006] Second, too many data storage requests will reduce the responsiveness of the SCADA system and affect the operation of other application processes

[0007] Third, a large number of database connections will cause the database load to be too high, and even cause the database to crash, directly affecting other processes' access to the database
