Research activities l.jpg

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 l.jpg

Technical Approach

  • Garage Door Scenarios:

  • Hard Wired Logic Circuit vs. Micro-Controller

  • Design vs. Purchasing a Transmitter/Receiver Unit

Implementation activities l.jpg

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 l.jpg

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 modifications20 l.jpg

…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.
