Challenge: A leading supplier of automotive service
equipment approached Intellicon to provide a controller for three
separate automotive service machines. Customer required machines
that were simple to operate, fail safe, and easy to maintain. Units
should also have commonality of spare parts to reduce the number
of spares the customer would need to inventory.
Analysis: Many of the sophisticated engine and transmission
service operations must be done with the vehicle's engine running.
Therefore, the equipment must operate precisely or leave the
service provider and equipment manufacturer open for liability
if the machine fails. Timing of service steps is also important
since pressures must be increased and decreased at precise intervals,
valves opened and closed, and correct amounts of detergents and
fluids added.
The units should also be portable, in a compact package, be
compliant to all OSHA and EPA requirements and run off the vehicle's
12 VDC power. Each machine must also have an update path for
future model service requirements. Moreover, the machine must
be cost-efficient.
Results: Working closely with the customer's product
development team, Intellicon engineers developed a unique two-board
solution that utilizes a common controller and a model specific
operator-machine interface.
The controller board uses a industry standard micro-controller
with a programmable flash memory that holds the system's service
routine. The board also has bi-directional motor control, up
to 8 solenoid drivers (depends on the unit), A-D converter for
measurements, closed loop PID, and full display functions and
input processing. To help program the units, an embedded Ethernet
option was included for future use.
The operator interface board and overlay is specific for each
machine and each application. Operators are prompted to push
buttons to machine prompts and instructions with read-outs provided
through a combination of LEDs, seven-segment displays, and LCD
screens. In addition, Intellicon engineers designed audible warnings
with variable tones to quickly alert service technicians about
the status of any process.
The
Proof: The design has helped the equipment manufacturer
reduce the number of spare parts for this equipment family
as well as improving control of the service project. The assemblies
reduced the manufacture's production time leading to a better
product that cost less to produce.
