Embodiment Construction

[0038] The technical solutions provided by the embodiments of the present invention will be further introduced below in conjunction with the accompanying drawings.

[0039] The database system provided by the present invention can be applied to existing large-scale computer monitoring systems, such as distributed control systems (Distributed Control System, DCS) and centralized data processing systems (Centralized Data Processing KIT) used in nuclear power plant systems. Since the processing flow in each system is similar, a distributed control system is used as an example for illustration.

[0040] The database system includes multiple database devices, and each database device manages the data points of the devices in the corresponding management area of ​​the distributed control system, wherein the management scope of the database device can be based on the coverage of the distributed control system The scope and processing power of the database device are divided.

Abstract

The invention provides database equipment and a system, relating to the communication field. The database system comprises at least one database equipment, the database equipment obtains the data point of equipment in a corresponding zone in the network and records the data point in the form of record items in a memory address corresponding to the record type of the data point in a memory address corresponding to the equipment; the corresponding identity information of the data point in the database equipment is configured, and the corresponding relation of the identity information of the data point and the memory address is built; the identity information comprises the item name and the item number of the record item; when an access request for accessing the data point is received, the access request comprises the identity information and the record item information of the data point; in the memory address corresponding to the identity information in the access request, the record item matched with the record item information in the access request is obtained, and the obtained record item is sent to an initiator of the access request.

Description

technical field [0001] The invention relates to the communication field, in particular to a database device and system. Background technique [0002] In the existing communication system, in order to meet the needs of production and industrial control, real-time databases are used to provide data to the outside, such as PI, PHD, eDNA and other database systems, but the above-mentioned database systems are expensive and do not meet the access speed of the self-developed industrial control system The requirements cannot be applied to self-developed industrial control systems. Contents of the invention [0003] The database equipment and system provided by the invention can quickly find the data to be located. [0004] In order to achieve the above object of the invention, the present invention provides the following technical solutions: [0005] A database system, comprising at least one database device, the database device acquires data points of devices in a correspondin...
