Problem Statement
To design a system for
testing the insulation integrity of boom trucks to assure
workmen they are insulated from ground when
working from the bucket.
Design Objectives
To View Current Remotely Use Existing Current Sensing System
and Techniques Process Current Using State of the
Art Components Produce Read Out on Hand Held LED Eliminate Pull Cord Low Battery Detection
End-Product Description
Simple attachment to present device Battery operated Transmitter and Receiver
with a range of 150 Ft Handheld Receiver with LED display
Assumptions and Limitations
Assumptions: The leakage current
will not exceed 2000 micro amps
The boom truck will only be in contact with one line at a time
The kV value and allowable current for the line is known
The appropriate safety procedures are followed
Limitations: The current will
range from 0 to 2000 micro amps
The receiver will be within 150 ft of the boom truck
Will only work in fair weather conditions
The duty cycle is limited to the battery life
Risks and Concerns
Limited amount of time for project completion.
Testing to insure accuracy.
Interference Ease of use
Evaluation of Project Success
Interface with present unit.
Data input to programmable unit
RF Transmission/Reception
Receiver display interface
Further Work
Adding a speaker or light system Resizing the probe assembly to
make it smaller. Design a stationary mounting point
for the receiver on the truck. Find lower cost devices for mass
production.
What We Have Learned
Meet with team members and advisors regularly
Review parts to be ordered carefully Keep group members involved Basic Stamp Technology RF Communications Testing procedures for Boom Trucks
