DCS terminal board outlet wire diagram automatic forming method

Abstract

The invention provides a DCS terminal board outlet wire diagram automatic forming method, and belongs to the technical field of thermal power plant engineering design. The DCS terminal board outlet wire diagram automatic forming method includes the steps of generating an essential data table: generating the essential data table of a DCS terminal board outlet wire diagram, determining a style: determining the style of the DCS terminal board outlet wire diagram to be generated, and generating the DCS terminal board outlet wire diagram: enabling the essential data table generated in the step of generating the essential data table to be automatically converted into the DCS terminal board outlet wire diagram conforming to the style determined in the step of determining the style. According to the DCS terminal board outlet wire diagram automatic forming method, the technical problem that manual drawing revision is complex and high in error rate is solved.

Description

technical field [0001] The invention relates to the technical field of thermal power plant engineering design, in particular to a method for automatic drawing of DCS terminal discharge lines. Background technique [0002] The conventional design method for the DCS terminal discharge line of the distributed control system is: the design institute provides the I / O list of the control system to the DCS manufacturer of the related project, and the DCS manufacturer completes the card arrangement list (EXCEL file) and the card arrangement diagram (CAD file), There is a one-to-one correspondence between these two files. The design institute compares the DCS card layout list provided by the DCS manufacturer with the I / O list previously provided to the DCS manufacturer. If there are no omissions, the designer copies each DCS card layout diagram into the standard frame required by the engineering design. , Responsible for the wiring design between the DCS card layout and the controll...

AI Technical Summary

Problems solved by technology

[0005] 1) On the basis of the DCS card layout diagram, the DCS terminal discharge line is manually drawn, and the design cycle is long

[0006] 2) Manually input the name of the controlled equipment, equipment number, cable specification model, cable number, and cable line number in the CAD drawing. The amount of input data is large and it is easy to make mistakes

Among them, the cable specifications and models are filled in by the designer according to the different types of DCS card parts and the number of cable cores. In the design, the wrong number of cable cores and the wrong card type are judged, resulting in data input errors.

[0007] 3) Differences in individual habits of different designers and different card layout diagrams of different DCS manufacturers lead to messy and untidy expressions on the finished product drawings

[0008] 4) In the design process, it is inevitable to adjust the I / O list. The designer manually modifies the drawings, which has a heavy workload and a high error rate
