Online – Particle – Automation
at EADS Airbus in Hamburg,
Germany
The purpose of the automation was to reduce the flushing time of the hydraulic
systems
during
the production of the aircraft types A319/320/321 considerably. This was
realized via
the automation of the particle measurement, which is now
used in each of the 40 runback lanes.
The flushing time could be reduced by two thirds compared to
the former time.
The firm digi
plan GmbH has developed an own software packet to realize this task.
The (FMC) Facility Monitoring Center and
special electronic particle counters and frequency
modules developed by digi plan were used in the combination with
the (DAS)
Data Acquisition
System, which is modular designed.
The
FMC-software which was developed for the particle measurement, runs on the WIN NT4.0
operating system and is absolutely
independent. The software within the DAS controls and
regulates the 40 complete particle
measure lines including the tabular or graphical evaluation
and event protocols. Furthermore,
40
temperature dependent flow regulations are controlled
by the system which grant the turbulent stream within the pipelines
during the flushing process.
The single DAS-frames communicate
via a Rail Switch per Ethernet with each other.
The data exchange to the superior PLC Siemens S7-400 of the complete hydraulic
station
was realized via a Profibus Layer 2 (FDL).
