Bowling Alley Communications

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.
15
FUTURE WORK I plan on extending this in some
way to all 32 lanes in the future. Questions, or Suggestions? [email protected]
