BREIN modules for glass coating production lines

This module reads data files generated by the Zeiss Optoplex NG.Q software. These files contain all spectra of a scan across the width of the pane, measured exsitu outside the coating line. The scanner module scans a transfer directory for new data. Both the Optoplex software and the scanner program must be able to read and write to this folder.

Once a data file is found the scanner generates a special transfer file (extension *.scn) and stores it in the appropriate BREIN subdirectory so that it gets analyzed by the bright_eye_traverse.exe analysis module. Bright_eye_traverse.exe must be configured to look for *.scn files in this case.

The Zeiss scanner software reads the file brein_scanner.ini at start-up. The individual lines of this file have the following meaning:

Line #	Meaning	Example
1	Transfer path	h:\zeiss_transfer\
2	Bright eye	BE5
3	Flag to indicate automatic product identification	False
4	Number of scan files to be created	1
5	Number of spectral positions in the Zeiss data file	125

The setting of line 4 controls how many scan files are generated. The default value is 1. In this case a scan file with the extension *.scn like 45467.scn is generated. If 2 or more scan files are generated, the individual files get extensions like *.sc1, *.sc2, and so on. In this case several instances of the bright_eye_traverse program must be used, each of which handling one type of scan file. This is usually done by running each instance of bright_eye_traverse on a different PC, increasing the total available computational power this way.
