Method and system for retrieving instrument-related items in three-dimensional database of nuclear power plant

Abstract

The present invention provides a method and system for retrieving instrument-related items in a three-dimensional database of a nuclear power plant. The method includes establishing an additional information virtual point of an instrument related item under an instrument pipeline layer in a database model according to a PID diagram; performing a correlation check on the additional information virtual point and the instrument related item; calling and displaying the additional information virtual point through the additional information virtual point All items associated with the currently clicked item. The present invention retrieves the items associated with the instrument by creating a virtual point of additional information of the associated items of the instrument to ensure the validity of the retrieval; and through the connection with the database through the PML language, it can be quickly read and retrieved, and the operation time is displayed in seconds. ;In the program file, the characteristic information of the additional information virtual point under the instrument pipeline and the name of the related item are used synchronously, and the correlation between the two is checked to ensure the accuracy of the call, and at the same time, it can timely detect and remind other professional models. Condition where process piping or equipment coding does not match the PID diagram.

Description

technical field [0001] The invention relates to the field of nuclear power plant three-dimensional database design and management systems, in particular to a method and system for retrieving related items of instruments in the nuclear power plant three-dimensional database. Background technique [0002] At present, the layout of all items in nuclear power plants is designed in PDMS (Plant Design Management System: Plant Design Management System) through three-dimensional models, completing the innovation from traditional two-dimensional design to three-dimensional design. PDMS, as an international factory design management system, is used by more and more domestic fields and users to carry out three-dimensional layout design. Through the 3D design management system, various disciplines can carry out collaborative design in different places at the same time, and items between various disciplines can be better optimized and arranged. However, there are many professional items...

AI Technical Summary

Problems solved by technology

[0004] 1) The operation steps are lengthy and time-consuming. It needs to be retrieved from the model command line or CE module in combination with the PID diagram

[0005] 2) Entering and recalling commands one by one, the workload is heavy, and the working process is tedious and cumbersome. When the command editing error occurs, the database will report an error prompt, and you need to re-check and enter the command;

[0006] 3) Since the CE module in the current database does not support fuzzy query (that is, the correctness must be guaranteed from the first digit of the item code to the last), there may be problems such as errors in the codes of each specialty in the model, and the corresponding item cannot be found , will affect the design and verification process
