The Beijing male Viet Nam science and
technology development limited company according to the PLC system the
characteristic, used the modularized program design method and the
artificial intelligence technology, the success has developed the
on-line real-time monitoring and the breakdown diagnosis system, has
realized the PLC system comprehensive monitoring and the breakdown
diagnosis automation. This system not only has conventional the
historical parameter record, the behavior record, reports to the
police function and so on event record, picture demonstration,
tendency chart demonstration, statistical report form. Moreover
after can be fast, the accurate search instantaneous appears the
breakdown which breakdown I/O and occurs namely restores (for example:
The line contact is not good)
This system obtains the successful application in some
cold rolling sheet-metal mill rolling mill and the smooth production
line. Rolls over 机线and smooth each set of GE FANUC Corporation's SERIES SIX PLUS PLC, the actual I/O control point
respectively is 1,200 with
Nearly 1,000, the man-machine connection only has
operates terminal OIT, cannot the comprehensive monitoring equipment
condition. Before in the production process once the equipment
appears the breakdown to create stops, specialized engineer must with
the programming through the analysis trapezoidal chart procedure
search breakdown spot, often want a flowered longer time.
Sometimes the question appearance is because creates to the
equipment misoperation, because the system does not have the behavior
record function, like this very difficultly carries on the judgement
and processing to the question. Uses INTEL for this us 486 industries PC through GENIUS LAN and the rolling mill, smooth line PLC is connected,
the constitution centralism monitoring and the breakdown diagnosis
system, has realized the equipment comprehensive monitoring and the
breakdown diagnosis automation. This system investment greatly
enhances the PLC control system the maintenance level, original causes
the breakdown the search time from several dozens minutes, several
hours, several days to reduce is even several seconds, to original
artificially is unable the breakdown which searches to be able
accurately to diagnose, and to the breakdown forecast, the reduced
misoperation, the elimination accident hidden danger, the optimized
equipment management the vital role, has obtained the good economic
efficiency. |
