BRD file data automatic analysis method and device

Abstract

The invention provides a BRD file data automatic analysis method and device. The implementation process comprises the steps of S101, obtaining and sending a BRD file to a directory designated by a production system server; S102, reading the BRD file content, and converting the BRD file content into a binary data stream; S103, converting the data stream into a file structured object; S104, according to the column header format of the patch information of the BRD file, extracting the patch information content in the file structured object and converting the patch information content into a CSV file, the column header of the CSV file being consistent with the column header of the patch information of the BRD file; and S105, storing the converted CSV file to the server. According to the methodand device, one-key batch analysis of the BRD files is achieved, one-key matching proofreading of the BRD files and matched material sending information is supported, the bottleneck problem of electric fitting production is solved, the satisfaction degree of users is increased, and the production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of file analysis, and relates to a file data analysis method and device, in particular to a BRD file data automatic analysis method and device. Background technique [0002] BRD file refers to the design file created by the electronic design automation program of printed circuit board or PCB software, including component specification information, bit number information and coordinate information, etc., and is the source file of Denso production. After in-depth discussions with enterprise users, it is found that in the current production process, the analysis of BRD files consumes a lot of human resources, which seriously affects the production and inspection progress of Denso, mainly reflected in the following aspects: [0003] (1) BRD files cannot be recognized by electrical equipment, and the manual conversion process is cumbersome [0004] During the production process of Denso, the user needs to send the placeme...

AI Technical Summary

Problems solved by technology

However, BRD files cannot be recognized by automatic placement equipment, nor can they be recognized by AOI equipment. Users need to manually convert BRD files into recognizable file formats. Therefore, users need to frequently open design files and perform import and export operations during the production process of Denso. Cannot be automated, the process is repetitive and cumbersome, time-consuming and labor-intensive

[0005] (2) The BRD file cannot be updated in time according to the actual situation, and manual matching and proofreading is required

[0006] The production mode of military manufacturing enterprises has the characteristics of multiple varieties and small batches, and there is a phenomenon of immature technology. During the production process, the specifications of electrical components are often changed according to the actual situation. However, once the BRD design file is formed, it is often not modified, and cannot be timely based on demand. Update, so the content of the general BRD design file cannot be directly used for electrical equipment, and the user needs to manually match the BRD file and the supporting material delivery information according to the actual supporting material delivery situation, and generate a device-readable structured electrical equipment information file for production inspection

Due to the large variety of components and large consumption, the manual matching and proofreading process consumes a lot of time and energy of the user, which is the bottleneck of production

[0007] (3) There is currently no mature domestically produced software for parsing BRD files

[0008] Through market research, it is found that the production drawing files (BRD files) created by professional software on the market are difficult to process data except for opening and data processing by professional software.

At the same time, the professional software for creating and analyzing BRD files is not independently developed in China. BRD files are widely used by military and aerospace enterprises in my country, but it is very difficult to integrate with the production execution system, resulting in high development costs and difficult expansion.
