Distributed control system measurement point data import method, system, equipment and medium

Abstract

The invention discloses a method, system, equipment and medium for importing measuring point data of a decentralized control system. The importing method includes the following steps: modifying the pre-acquired measuring point inventory into an importing point table suitable for DCS; traversing the importing point table In the measuring point, the measuring point in the described imported point table is constructed as the measuring point object of DCS and added to the point table object linked list; the measuring point object is taken out by traversing the point table object linked list, and the measuring point object is checked; The measuring point objects checked by the parameters are added to the imported measuring point list, and the measuring point objects that do not meet the parameter inspection are added to the error information linked list; based on the pre-acquired import type, the measuring point objects in the imported measuring point linked list are filled into the DCS data stack , complete the import of measuring points to form DCS data configuration. The invention can solve the technical problems of low efficiency and poor accuracy when adding a large number of data measuring points or modifying the parameters of the measuring points in the existing DCS.

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
