Problems solved by technology

The above-mentioned existing traditional methods not only need to spend a lot of labor costs, but also need to avoid errors caused by manual operation, and the reliability is poor. When performing database operations on DCS, certain technical means are required. estimated loss
[0006] To sum up, the current traditional DCS I / O channel measurement point export is not convenient for the operation and maintenance or transformation of thermal power units, and a new distributed control system measurement point export method and system is urgently needed

Embodiment 1

[0036] see figure 1 , a method for deriving measuring points of a distributed control system based on forest preorder traversal in an embodiment of the present invention, comprising the following steps:

[0037] Constructing the hierarchical data structure of the distributed control system as a forest data structure; exemplary and optional, the forest data structure may be a preset multi-level height forest data structure;

[0038] Use the forest preorder traversal method to export the measuring points to the preset export template to complete the export of the distributed control system measuring points.

[0039] The above method in the embodiment of the present invention can improve the work efficiency of the user, greatly reduce the DCS data maintenance workload, and can also improve the accuracy of the data through the automatic export of the system.

Embodiment 2

[0041] In the embodiment of the present invention, taking the hierarchical structure of the unit-controller-branch-module-channel of DCS as an example, the steps of constructing the hierarchical data structure of the distributed control system as a forest data structure specifically include:

[0042] DCS is composed of a unit-controller-branch-module-channel hierarchical structure. There are multiple controllers under the unit, multiple branches under each controller, multiple modules under the branch, and multiple channels under the module. According to the hierarchical structure of DCS, it can be constructed as a forest structure with a depth of 5. The unit is the root node of the first tree in the forest structure, the controller is the child node under the unit node, and the branch is the child node under the controller node. The module is a child node under the branch node, and the channel is a child node under the module node, which is also a leaf node.

[0043]In the em...

Embodiment 3

[0045] In the embodiment of the present invention, the export template is the data table of the I / O channel measurement point, and the table name and header column name in the data table are corresponding to each node attribute name in the DCS. According to the forest data structure, the module node Create a table page for the module type name, and add the unit number column, controller number column, branch number column, module number column and channel attribute columns to the table page to form a table header. The unit number, controller number, branch number, module number and channel number constitute the position information of the I / O channel measurement point in DCS, and the position information is unique, so the unit number column, controller number column, branch The number column, module number column, and channel number column cannot be empty, and the label name of the measuring point in the thermal power unit is also unique, so the column of the label name of the ...

Abstract

The invention discloses a distributed control system measurement point derivation method, system, terminal equipment and a readable storage medium. The method includes the following steps: constructing the hierarchical data structure of the distributed control system into a forest data structure; Data structure, using the forest preorder traversal method to export the distributed control system measurement points to the preset export template, and complete the distributed control system measurement point export; wherein, in the preset export template, the I / O channel measurement The unit number, controller number, branch number, module number, channel number and label name of the measurement point are used as keywords, and other attribute information of the I / O channel measurement points are used as parameter items. In the present invention, the data measuring points of the DCS can be exported as a table, and based on the derived table, the statistical analysis and batch modification of the parameters of the DCS data measuring points can be realized, which can reduce labor costs and improve reliability at the same time.

Description

technical field [0001] The invention belongs to the technical field of industrial control systems and DCS data processing, and in particular relates to a distributed control system measurement point derivation method, system, terminal equipment and readable storage medium. Background technique [0002] As described in the book "Principles and Applications of Distributed Control Systems in Thermal Power Plants", distributed control systems (DCS) have been widely used in the field of industrial control. For thermal power units with numerous field devices and complex control processes, a DCS with excellent performance and friendly functions can play a vital role in the construction, operation and maintenance of thermal power units. [0003] The commands, feedback and other signals of the thermal power unit control equipment are connected to the DCS through cables, and the equipment signals are associated with the DCS in the data form of I / O channel measurement points according ...
