Possible Approaches
Building a Transmitter/Receiver from scratch vs. Buying a
Fabricated Unit
Building a “Hard-Wired” Logic Circuit vs. Signal Processing
Different Types of Sensors for Input





Pressure Pad for Tire
Contact Limit Switches
Magnetic Switches
IR (Obstruction) Sensor
Light Sensor
Using Openers with Exterior Contacts vs. Determining the Internal
Circuitry
Solution Approach
Scenarios:

Four-button Controller
 Transmitter/Receiver
 Wall Mounting
Research Activities
Research:
Internet and Advisors


Transmitter/Receiver – located and purchased online
Relays – located and purchased online
Micro-controllers – used ISUs HC11
Sensors – Door Store, Previous Lab Projects
Free Door Opener:
Sears 1/3 H.P. Rail type - Chain driven


Manufactured in 1992
Not Compatible with Recent Obstruction Sensors
Technical Approach
Garage Door Scenarios:
Input
Remote Controller Signal
Main Controller Signal
Open Indefinitely
Keypad Signal
Open Indefinitely
Immediate Close
Open and Cycle Close
Hard Wired Logic Circuit vs. MicroController

Implementation Activities
Problems Encountered:
Downloading Code to Motorola HC11E9 EVBU Board

Switched to Motorola F1HC11 Board that was used in Cpr E 211.
Important Part of Magnetic Sensors Missing

Part Built into Genie Systems. Changed to Contact Limit Switch.
Obstruction Sensors Not Compatible with Door Opener

Eliminate Obstruction Sensor as input to SGDS because of FCC
Regulation in 1993.
Testing and Modifications
Testing:
SGDS Broken into 7 Different Individual Tests
Tested as whole afterwards
Test 1 – Transmitter and Receiver:
Apply Power, Measure Output at Relay
Test 2 – Momentary Push Buttons:
Figure out Wiring Scheme
Test 3 – Relays:
Apply 5V to Coil and use Ohmmeter to test the resistance between
NO and the Com terminals
…Testing and Modifications
Test 4 – Garage Door Opener:
Power Opener and Determine Terminal Functionality
Test 5 – Light Detection Circuit:
Build Circuit from Schematic and test with a flashlight to see if the
Voltage Signal disappears when incandescent light is visible.
Test 6 – Contact Limit Switch:
Wire a series circuit and make sure the NO circuit changes to closed
the the contact is closed.
Test 7 – Micro-Controller:
Download the program to the hardware, send in input signals with a
source to different pins and check the output for a signal.
