Explosive data cache processing system and method for scada system

Abstract

The invention discloses a SCADA system-oriented burst data cache processing system and a method thereof. The system includes: a data receiving module, a file cache module, a data pre-reading module, a queue cache module, a data optimization module, and a thread pool module; among them, the data receiving module receives the data storage request message sent by the application program, and according to the state of the cache queue Put it into the disk cache file or cache queue of the file cache module; the data pre-reading module inserts the data storage request stored in the file cache module into the cache queue; the data optimization module reads the data storage request in the cache queue, and the data storage After the request is optimized, the idle thread in the thread pool is called to perform data storage operations. The invention can better solve the security problems of the requested data and the SCADA system when submitting a mass data storage request.

Description

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

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
