Embodiment Construction

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0022] For the real-time database management system applicable to electric power systems of the present invention, the overall frame structure of the system is shown in figure 1 As shown, among them, hs_dispatcher represents the server, DB_API represents the client, and the server, real-time database and client communicate with each other. The specific instructions of the server, real-time database and client are as follows:

[0023] 1. Server: Complete relevant configuration information, configure system resources required for system operation, manage instances, points, etc., and cache all instance information and simplified point information on instances to ensure data uniqueness and consistency. Due to the large cache data, there are certain requirements for the server memory size. The server manages the registered instances, the points on eac...

Abstract

The invention discloses a distributed real-time database management system and an implementation method applicable to an electric system and belongs to the field of database technologies. The real-time database management system comprises a server side, a real-time database side and a client side. The distributed management of real-time databases can be achieved through mechanisms such as file mapping, instance IDs, version numbers and client side caching. Through the distributed real-time database management system and the implementation method applicable to the electric system, transparency of multiple database instances is achieved, access of clients to the multiple database instances equals to access to a single database instance, the province-wide centralized deployment of the databases are facilitated, the province-wide unified data schema, data models and data standards are facilitated, and the access requirements of existing data and future data can be met.

Description

technical field [0001] The invention belongs to the field of distributed real-time databases, in particular to a distributed real-time database management method. Background technique [0002] With the continuous deepening of industrialization and informatization "integration of industrialization and industrialization", industrial automation systems are facing increasing pressure to process massive data. Taking the power system as an example, with the continuous expansion of the scale of the power grid and the deepening of research and application of digital power grids and digital substations, the system faces more and more collection points. The collection volume of a medium-sized area can reach 20,000 to 100,000, and a large-scale survey may face a data collection scale of 200,000 to 1 million in the future, and the data center can reach 5 million to 10 million or even tens of millions of data collection scale. [0003] The single database management method currently us...
