A method and system for automobile wire harness process planning based on CAD platform

Abstract

The invention belongs to the technical field of automobile wire harness design, the invention discloses a process planning method and a system of automobile wire harness based on a CAD platform, adopting the ARX development environment of C + + language supported by CAD platform, editing various command modules, and combining the original commands of the CAD platform to establish the information database of wire harness parts, establish the wire harness process parameter database, draw the drawings, set the internal connection points, set the matching parts, and perform process generation andoutput operation. The invention realizes intelligent recognition of wire harness drawings and fast input of wire harness structure information by a rule-based wire harness segment recognition method and an electric device pattern recognition method based on a fuzzy support vector machine (Fuzzy SVM). Combining the Pareto optimal solution with genetic algorithm, the inline process planning optimization method based on the strategy of seeking the optimal solution first and then decision-making is adopted to realize the intelligence and optimization of the inline process planning.

Description

technical field [0001] The invention belongs to the technical field of automobile wire harness design, and in particular relates to a CAD platform-based automobile wire harness process design method and system. Background technique [0002] The wire harness refers to the contact terminal (connector) punched from copper and the wire and cable after crimping, and then plastic insulator or metal shell on the outside, and then bundled with wire harness to form a connected circuit component. The automobile wiring harness is the network main body of the automobile circuit. With the improvement of people's requirements for the safety, comfort, economy and emission of automobiles, the automobile wiring harness has become more and more complex, and various wiring harnesses need to be designed and counted. [0003] At present, the existing technologies commonly used in the industry are as follows: [0004] Existing technologies often draw on a CAD platform, and then export to other s...

Problems solved by technology

[0006](1) The traditional way is to manually query the process manual and calculate the statistical line number path, which consumes a lot of labor costs, and the accuracy is difficult to guarantee, requiring repeated accounting, which is inefficient , has been far from meeting the needs of enterprise production, and cannot meet the requirements of enterprise informatization;

[0007](2) The traditional method fails to establish a standardized process knowledge base, which makes it difficult to ensure the accuracy of the process and accumulate corporate process knowledge;

[0008](3) The traditional method has high requirements for the skills of craftsmen, and the enterprise has high training costs for employees;

[0009](4) The traditional method stores the process data in the form of Excel or paper files, the cost of file management is high, and it is difficult to connect with ERP, MES and other systems
