Radial Low-Point Marking System
Designed and implemented an industrial computer interface to a low point
marking system for a tire rim manufacturer. The system ran under MS-DOS using
a graphical user interface. The system communicated to Allen-Bradley PLC's
via an RS-232 connection and to a data acquisition board and 4 axis motion
controller using direct memory addressing. Each tire rim was placed on a
carousel by a robot then the software would spin the rim, take over 2000
measurements of it and then use those measurements to calculate various
harmonic statistics on it. These calculations were the basis for rejecting
or accepting the rim. Accepted rims were then repositioned to the radial low
point for marking by a press.
Ultra-Violet Purification Monitoring System
Developed an operator interface for an ultra-violet light water
purification system. The interface was developed using a graphics interface
product called WonderWare and the application communicated with the PLC's
data highway using Allen-Bradley KT1728 cards. The interface was a graphical
representation of the system with flowing water, gates that opened and closed
and provided complete control over the UV lamps in the banks.
Statistical Process Control (SPC) System
In continuation of the lowpoint marking system, Generated Solutions
developed a statistical process control (SPC) package to permit the
customer to leverage the vast amounts of collected data to improve their
manufacturing processes. The system performed complex univariate, bivariate
and SPC analysis on the data and presented the results in both graphical and
tabular form. These results were then used to recommend adjustments to boring
heads and other machine components in order to improve the production.
Industrial Downtime Monitoring System
A final addition to the low point marking system was a downtime monitoring
and recording system for the entire manufacturing line. This system ran under
MS-Windows and utilized DDE conversations between communicating tasks to
monitor all the PLCs on the line and record all down time events. When a down
time event occured its start time, end time and duration were databased along
with details concerning which machines were involved, product being produced
and personnel involved.
