BackgroundThe LoDril currently has two
instrumentation panels Level/Depth Display Control Box
Permanent custom mounting Impossible to satisfy the various
preferences of operators

Problem Definition To create a touchscreen interface for providing
feedback on the primary LoDril controls. Develop a desktop model that simulates the primary
LoDril controls. Easy integration into the current control system Using modular based thinking Designed fro the rugged construction environment

Project Requirements Completed 7 Base Signals for instrument panels
One analog voltage input for fore/aft leveling One analog voltage input for left/right leveling Quadrature counter input for shaft depth One analog voltage output for speed/torque
adjustments Selection switch between LoDril/Excavator Selection switch between Kelly/Service Winch Selection switch between High/Low Speed

Anticipated DeliverablesState of the art display for the LoDrilDesktop model that demonstrates the
functionsEasy to understand and see screensMobile mounting system, flexible for
different cabs

Concepts Considered Micro-Controllers
Relatively inexpensive Easy to write
programming Cannot change code
on the fly No experience –
lengthy learning curve
Programmable Logic Controllers Expensive Easy to write
programming Can change code on the
fly Discrete input and
output combined with optional cards
