Task description

to create computing infrastructure for straw data transfer from PC in the clean room to remote server data base,

to do estimation of the proposed client-server architecture, writing script for testing

Tools for realization Microsoft Windows XP PC with a TCP/IP network

connection, installed iuVCR – video recording program, PicoLog – data acquisition tool, that collects,

records, displays and analyses measurement data, MATLAB-written program of seam snapshots classification (_bad, _good

folders), WinSCP – open source SFTP client, SE342 for Recorder is a software for download data from

Thermo Recorder which is connected with a PC Cisco Linux remote blade server with installed

straw, data base (Apache + MySQL + PHP)

Straw data

straw seam snapshots .bmp files with classification into _bad, _good folders, with names in the format

year-month-day_hour-min-sec, welding machine generator

frequency, humidity, temperature vs. time plots, .bmp files

Developed system client-server architecture + .bat script

for programs opening and straw data transfer

Steps of improvements Perl installation and script optimization,

e.g. with nnCron - an advanced and very powerful scheduler, scripting tool and automation manager,

data link change (GE, optics), multi-tasking mode, parallel data

transfer and data processing, traffic measurement,

signal processing from portal robot (welding machine test bench) sensors

Conclusions

straw data transfer client-server architecture is created,

script software is written, link between clean room and

remote server data base is perfomed
