Problems solved by technology

[0002] In the design of petrochemical engineering, a large number of instrument circuit diagrams have to be designed. In the traditional sense, the method of drawing one by one is used, which is very cumbersome.
[0003] The intelligence provided by the INtools software itself has some limitations. It is impossible to construct a model suitable for various applications, and then design an automatic and intelligent data processing mechanism on this basis, thereby restricting software users to Make choices and settings that result in less productivity

Embodiment Construction

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0013] The approximate design of the instrument circuit diagram of each project is relatively consistent, mainly divided into instrument index (Index), DCS cabinet, electrical instrument connection signal, field instrument junction box, instrument connection terminal cabinet and emergency stop system. These documents must be the final version, or basically close to the final version (requires less modification), otherwise the instrument circuit diagram can only...

Abstract

The invention discloses a method for generating an instrument circuit diagram automatically. The method comprises the following steps: the original data sources of a plurality of types of instrument circuit diagrams are converted into information list with instrument labels, and the information list is guided into a first Excel document; the information lists are classified according to the preset instrument sequence so as to obtain the instrument indexes of a plurality of types; the data of the instrument indexes of a plurality of types are compared through Access, the instruments having the same tail number and belonging to the same circuit are extracted and guided into a second Excel document; an AutoCAD template file is built, the key codes of all the texts are obtained, after matching each key code with the row and column in the first Excel document, the corresponding cell data in the second Excel document is called to generate the circuit diagram.

Description

technical field [0001] The invention relates to the field of chemical instruments, in particular to a method for automatically generating an instrument circuit diagram. Background technique [0002] In the design of petrochemical engineering, it is very cumbersome to complete the design of a large number of instrument circuit diagrams. Traditionally, the method of drawing one by one is used. [0003] The intelligence provided by the INtools software itself has some limitations. It is impossible to construct a model suitable for various applications, and then design an automatic and intelligent data processing mechanism on this basis, thereby restricting software users to Make choices and settings that result in less productivity. Contents of the invention [0004] The invention provides a method for automatically generating an instrument circuit diagram, which is used to realize the automatic generation of the instrument circuit diagram and improve work efficiency.
