Problems solved by technology

[0003] During the application of DCS, sometimes it is necessary to set some mandatory values ​​for some variables (or measuring points). The forced values ​​of the variables will not change due to the execution of the user program, even if the DCS is exited, or the controller is powered off, or connected to the The online connection of the controller is disconnected, and the forced values ​​are kept in the DCS controller. Although forcing variables can provide variables for system debugging and operation, when the forced variables need to be released, there may be problems with the control of DCS. influences

Abstract

The application discloses a variable processing method, system, device and computer-readable storage medium, which are applied to a decentralized control system to determine the value of a mandatory variable to be released, and the value of the mandatory variable includes the value obtained after a mandatory operation is performed on the target variable; The original value of the target variable is displayed. The original value includes the value obtained by the target variable based on the configuration logic operation; the impact information after the forced variable value is estimated based on the forced variable value and the original value; the release of the forced variable value based on the impact information process control. In this application, after the distributed control system determines the mandatory variable value, it also needs to obtain the original value of the target variable and display it, so that the user can know the corresponding information of the original value, and it is necessary to estimate the impact on the distributed control system after the mandatory variable value is released. Influence information, and finally control the release process of mandatory variable values ​​according to the influence information, realize the control of variable release, and control the influence of variables on the decentralized control system.

Description

technical field [0001] The present application relates to the technical field of distributed control systems, and more specifically, to a variable processing method, system, device, and computer-readable storage medium. Background technique [0002] Distributed Control System (DCS) is a new generation of instrument control system based on the microprocessor, which adopts the design principles of decentralized control functions, centralized display and operation, taking into account the design principles of division and autonomy and comprehensive coordination. It adopts the basic design idea of ​​decentralized control, centralized operation and management, adopts a multi-layer hierarchical, cooperative and autonomous structure, and its main feature is the centralized management and decentralized control of DCS. At present, DCS has been widely used in various industries such as electric power, metallurgy, petrochemical and so on. [0003] During the application of DCS, someti...
