Embodiment Construction

[0020] The design scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 Shown is the network connection diagram of the real-time library management module used in the distributed control system. Due to the complex process of the distributed control system, taking the control process of a power plant as an example, it is generally divided into three main control systems: electrical system, main control system, and auxiliary control system. The acquisition equipment in each control system and the length and type of data collected by the equipment are very different, which brings certain difficulties to the power plant to realize the data information sharing of the whole plant. The real-time library management module summarizes the common parts of the acquisition equipment and the intelligent communication equipment. When defining the data structure, three data types are abstracted, whic...

Abstract

The invention discloses a real-time library management module used for a distributed control system. The real-time library management module is the core module of the distributed control system, is used for storing real-time data gathered or collected by the control system, and is used for providing a data source for a communication module and a logic calculation module; store units of three data types, i.e. an IO (input / output) data type storage unit, an IED (intelligent electronic device) data type storage unit and an imaginary point data type storage unit, are designed by the real-time library management module; the adaptability and the transportability of the real-time library management module are enhanced; and for realizing data information sharing among different control systems, a parallel node data storage unit is established by the real-time library management module to manage the quality bit and the data bit of a network variable. According to the real-time library management module used for the distributed control system, which is disclosed by the invention, a real-time data source can be provided for information sharing and data exchange among control systems, and meanwhile, comprehensive data support is provided for the production operation of an automatic system.

Description

technical field [0001] This application belongs to the field of distributed control technology, and mainly involves the automation of large-scale power plants, petroleum, chemical industry, metallurgy, rail transit and other industries; the real-time library management module in this application is the core module of the distributed control system and is used to store Collected or collected real-time data, and provide data sources for communication, logic computing and other modules. Background technique [0002] At present, the establishment of real-time library of distributed control system generally describes the points according to the physical meaning, which is divided into digital input, analog input, digital output, analog output and other types. Due to the complex process of the distributed control system, taking the control process of a power plant as an example, it is generally divided into three main control systems: electrical system, main control system, and aux...
