The Product Verification
System (PVS)
The Product
Verification System, PVS, was designed to constantly monitor and compare a
container’s bar code label to an identification module affixed to a
part’s quality control gage. When a mismatch occurs, the state of a
relay output will change to signal a fault condition.
Features:
-
Designed to yield a fail
safe 100% quality assurance level.
-
Compact and rugged
industrial design.
-
Modular design or
easy setup and production changes.
-
Operator designed setup for
fast production changes.
-
PDA Operator interface for
system test and programming via a standard hand held device (PDA).
-
Production tested to insure
reliability, maximize ease of use and minimize operator error.
Benefits:
-
100% verification that the
product produced is loaded into the correct container.
-
Real-time alert (light
stack, audible or line stop) when a mismatch or other error occurs.
-
Operator error is virtually
eliminated.
-
Maintenance free design
-
Compact size enables easy
retrofit and line integration on most production line equipment
-
Cost effective stand-alone
system when compared to other off the shelf solutions.

General
functional specs:
-
The
Control Module will handle the communications between the Identification
Module and the barcode scanner. There will be one module per
product.
-
The
Identification Module will contain the unique identification barcode
(alpha / numeric equivalent) for the reference gage. There will be
one module per gage.
-
Once
the Identification Module code and the bar match, the Control Module
will continuously (60 second interval) compare the Identification Module
code to the appropriate bar code on the label affixed to the product
container.
-
Should
the container label and the reference gage not match or the bar code
becomes unreadable or any other error occurs with the system, the
contact closure state will be changed to signal a “Bad” condition.
Control
Module (CM) description:
The Control
Module will handle the entire process control and programming of the
Identification Module. The module requires no setup or configuration other
than its physical connections to the system components. The module is
a self contained unit packaged in a heavy duty housing containing:
-
The
control system components and matching logic and monitoring software.
-
Power
source connector.
-
Bar
code scanner connector supplying power and communications.
-
Identification
Module connector supplying power and communications.
-
Identification
Module programming connector to enable programming of the module via a
handheld device (PDA).
-
Contact
closure connector.
Identification
Module (IM) description:
The
Identification Module is the absolute reference to the product bar code.
The module can be programmed only one time to provide the maximum quality
assurance. The programming will be handled via the Control Module with
the alpha / numeric equivalent of the bar code to be matched on the product
container. The module is a small self contained unit packaged in a
plastic housing containing:
