MOTIVATION Cut down on time

to fix lanes Eliminate

unneeded communications

Wanted project that was low budget.

3

INTRODUCTION Blackout communication has

always been done the same way. Never had any attempt at

improvement. No existing improvement found

online. Lot’s of wasted time as is.

4

PROBLEM STATEMENT Too much down time between

when a lane messes up and when the mechanic is made aware of the problem.

Wasting time finding error code for each lane.

5

PROPOSED SOLUTION List steps taken to solve the

problem such as: Brainstorming (gist of ideas tried) Proposed solution with justification Arranging for software/hardware Assembly Testing & troubleshooting Verifying results

This might continue on multiple slides

6

Ideas Interface the front display on

machines for error codes. Run signal from blackout lights to

shop. Hook buzzer up to alert mechanics. Use encoder/decoder to cut down

on wire.

7

Hardware Lots of wire Breadboards Logic Gates

and Chips LEDs or Lamps 24VAC Relays Power Supply

8

Assembly Created the circuit in

MultiSim. Tested in MultiSim and

it worked. Created the Encoder

with Logic Gates. Used a different Board

for Decoder Chip Tested in the Lab and

they were working properly.

Assembly (Cont)

10

Implementation Hooked relays

up to 24VAC bulbs on the lanes.

Used relays as a switch to close inputs for the encoder.

11

Implementation (Cont) Ran communication line from lanes

into mechanics area. Hooked communication line to

input for decoder.

12

Troubleshooting Had to get 6V batteries from the

lab. Had to use a wire to connect

grounds on both boards. Put a switchboard in to

troubleshoot. Causing lanes to mess up just to troubleshoot took too long.

13

Results Got the encoder/

decoder to work. Lot of

troubleshooting.

14

CONCLUSIONS This will be very expensive to

implement on all 32 lanes because of Relays.

A larger encoder/decoder, such as a 16:4 would work much better as it would save lot of money on wire.

Finding the right encoder would be far less troublesome.

FUTURE WORK I plan on extending this in some

way to all 32 lanes in the future. Questions, or Suggestions? mark.patterson18@gmail.com
