Manufacturing still depends on manual data collection involving a
'Clipboard'. The dictionary defines clipboard as a writing
board with a spring clip at the top for holding papers or a writing
pad. We also know that it is an area of memory in Windows used for
copying text and graphics. PDA based InstantHMI is
easily adapted as a tool for clipboard replacement. Clipboard
may be the only approach available to do things that are unplanned.
This is because Man is the most flexible and adaptable element in an
enterprise and with a clipboard in hand he can accomplish anything!
What can be done to improve manual tasks? Can we use available
technology to improve on 'Operator rounds' to collect data in a
methodical manner? Yes, we can conceive of a clipboard replacement
using a PDA or a tablet that provides for customizable forms for
manual data entry (including numeric or alphanumeric data, checklist
of items, pull-down list of choices etc.). The PDA
HMI can integrate Barcode and RFID information read by the PDA to
improve operations. Equipment can be immediately and absolutely
identified to check calibration information, repair parts, and other
vital information without unnecessary data entry.
A
wireless PDA with an RFID reader can be used to pull-up a data entry
screen appropriate to the machine where the operator is standing and
record/log the operator actions and comments. Sparing the
operator from the chore of recording when the data was recorded
(time stamp), where it was recorded (GPS location) and what the data
source is (RFID or barcode) can make the task more productive and
the information more reliable. Clipboard replacement technology is
not glamorous but effective while one continues to seek better
solutions to bigger problems. |
