Measurement point data import method of distributed control system, system and equipment and medium

Abstract

The invention discloses a measurement point data import method of a distributed control system, a system and equipment and a medium. The import method comprises the following steps: modifying a pre-acquired measurement point list into an import point table suitable for a DCS; traversing the measurement points in the imported point table, constructing the measurement points in the imported point table into measurement point objects of the DCS, and adding the measurement point objects into a point table object linked list; traversing the point table object chain table to take out the measurement point object, and checking the measurement point object; adding the measurement point objects conforming to the parameter check into an imported measuring point linked list, and adding the measurement point objects not conforming to the parameter check into an error information linked list; and based on a pre-acquired import type, filling the measuring point objects imported into the measuring point linked list into a DCS data stack, and completing measuring point import to form DCS data configuration. According to the invention, the technical problems of low efficiency and poor accuracy when a large number of data measurement points are added or measurement point parameters are modified in the existing DCS can be solved.

Description

technical field [0001] The invention belongs to the technical field of distributed control system and DCS data processing, and in particular relates to a method, system, equipment and medium for importing measurement point data of a distributed control system. Background technique [0002] Distributed control system (DCS) is widely used in power generation control of thermal power plants. When thermal power units are in new construction or renovation projects, they must first add the measuring point list of the design institute or the original measuring point list of the power plant to the DCS system. [0003] The measuring point list of the design institute or the original measuring point list of the power plant is often different from the system structure of the DCS. To add the measuring points in the measuring point list to the DCS, it is first necessary to manually organize the measuring point list to be suitable for the DCS system. structure, and then manually add the m...

Problems solved by technology

[0006] The purpose of the present invention is to provide a method, system, equipment and medium for importing measurement point data in a distributed control system, so as to solve the problem of low efficiency and low accuracy when adding a large number of data measurement points or modifying measurement point parameters in the existing DCS. poor technical issues

In the import method of the present invention, the data measuring points are imported into the DCS in the form of a data table, which solves the problem of increasing the measuring points and modifying the parameters of the DCS in batches; it can improve efficiency and accuracy, reduce manpower and time costs, and can satisfy a large number of DCS Timeliness requirements when measurement points are added or changed
