Problems solved by technology
[0003] In order to solve the problem of low performance of real-time data access in a conventional manner, the purpose of the present invention is to provide a device and a processing method for improving the performance of real-time database data processing. The device writes massive data read from the real-time database into the shared memory by running multiple data reading node programs at the same time, and the data processing program takes out and processes the data from the shared memory, and then writes the processed results into realtime database

Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] A specific process of a device and a processing method for improving the data processing performance of a real-time database is introduced as follows:
[0038] The feature of the real-time database data access SDK is that each data reading node program can only have one access instance. Even if multi-threading technology is used, it will eventually be constrained in the form of locks and ensure that in the concurrent state, the threads pass through the queue. way to use the access instance. However, if multiple data reading node programs are started at the same time, each data reading node program can have its own access instance, so that multiple access instances can read data in parallel, thereby improving the efficiency of data reading .
[0039] The data of each data reading node program is isolated using processes. For security reasons, the dat...

The invention discloses a device for improving data processing performance of a real-time database and a processing method, and the device comprises the real-time database which is used for storing production real-time data collected from each power plant; a plurality of data reading node modules which is internally provided with data reading node programs, arranged in the computing server, reads the production real-time data in the real-time database in parallel and stores the read data into the shared memory database; and a data reading node monitoring program arranged in the data reading node monitoring module and used for starting the data reading node program and distributing the measuring point table of the real-time database to each data reading node module. A plurality of data reading node programs is operated at the same time, mass data read from a real-time database are written into a shared memory, a data processing program takes out the data from the shared memory and processes the data, and then a processing result is written into the real-time database.
Description
technical field [0001] The invention relates to the technical field of computer server development, in particular to a device and a processing method for improving the data processing performance of a real-time database. Background technique [0002] When developing a business system based on real-time data, it is necessary to use a real-time database as a data storage medium. Common databases on the market include PI, Rython, etc., and these databases provide SDKs for data access to business systems. Considering the pressure on database access, these SDKs generally do not support multi-threaded parallel access. Therefore, in some cases where millisecond-level calculations are required and the amount of data is relatively large, the performance of real-time data access cannot meet these services in the conventional way. Contents of the invention [0003] In order to solve the problem of low performance of real-time data access in conventional methods, the object of the p...
