Hydropower station equipment maintenance operation instruction automatic generation method based on genetic algorithm

Abstract

The invention relates to a hydropower station equipment maintenance operation instruction automatic generation method based on a genetic algorithm. The method comprises the following steps: accordingto an original drawing, using professional software for modeling unit equipment, and forming a three-dimensional model base; establishing associated knowledge data of equipment maintenance by utilizing a coding technology and a digitization technology; utilizing the directed constraint graph and the constraint matrix to establish a geometric constraint relationship of the equipment parts; establishing an evaluation function of an equipment overhaul and disassembly sequence through three indexes of direction change, tool replacement and spatial movement distance; automatically solving a disassembly sequence based on a team genetic algorithm; and realizing multi-information presentation of the three-dimensional visual operation process of equipment maintenance by utilizing a 3D engine, visual angle adaptive control and a multimedia technology. According to the invention, the problems of limited expression, high understanding difficulty and low automation degree of a paper maintenance operation instruction book can be solved, the three-dimensional visual maintenance operation instruction book of different maintenance projects of equipment is realized, and maintenance guidance is quickly provided for a maintenance site.

Description

technical field [0001] The invention relates to the technical field of digital operation instructions, in particular to a method for automatically generating operation instructions for maintenance of hydropower station equipment based on a genetic algorithm. Background technique [0002] In recent decades, with the continuous improvement of computer graphics processing capabilities, CAD software has become an indispensable tool for 3D visual aided design and training industries. It has played an irreplaceable role in reducing the difficulty of understanding and enriching the expression of information content. From the previous information representation in two-dimensional space to three-dimensional space. [0003] At present, computer-aided software AutoCAD, SolidWorks, Pro / Engineer, UG, etc. are already necessary tools for 3D mechanical design, which can quickly realize 3D visualization of mechanical equipment; 3DMax, Maya and other software are based on the models generate...

The invention patent "A Method and Device for Automatically Generating Intelligent Station Maintenance Operation Instructions" (patent number: ZL201510837139.6) applied by the State Grid Corporation of China obtains the information of the corresponding equipment through the identification information of the equipment, and then according to the user's selection instructions Filter and logically match related information, and automatically generate on-site operation instructions. This patent is mainly in a static form. It is expressed in words, which is less intuitive and lacks presentation of the dynamic maintenance process.

[0005] At present, the maintenance operation instructions for equipment maintenance on the hydropower station site are still mainly in the form of printed paper, which lacks visual expression, poor intuition, and is difficult to understand; the level of intelligence is insufficient, and some are mainly based on pre-made guidance animations, and the editing efficiency is low.
