Raising the Bridge...Automation with Arduino

colporteur

image

This design challenge presented itself at an opportune time. The model railroaders are putting the finishing touches on a bridge that requires some automation.

On the other side of the bridge is a turn-about that the tug (A) needs to reach in order to change direction. I have been asked to create the following automation sequence.

Tug triggers sensor (A) to indicate the bridge needs to raise.

Gate (B) lowers indicate no traffic to enter bridge

Bus (C) stops.

Ramp (D) re-aligns to make room for bridge movement

Bridge (E) raises.

I suspect a button (no letter on the image) on the turn-about side will be required to indicate when the tug has completed it transition and the bridge can be restored.

My initial assessment is two inputs and four outputs.

Inputs

Tug Trigger

Operations Trigger

Outputs

Motor control bridge gate

Power interruption bus

Motor control bridge ramp

Motor control bridge

I am hoping to use a Arduino Uno for the project. If you have an extra to spare you can throw it my way.

    I watched some show, can't recall from where, that examined some of the back end stuff. Like all greener grass I thought man wouldn't that be a cool job? There is a person responsible for just air planes. If they offered technical tours, I would visit Germany just to attend. I don't know what my spouse would do there:)

    It was fascinating to learn how  the banks agreed to fund the startup project and what it has morphed into. I would carry a personal sense of pride if I was part of the support team. I worked in aviation system design and implementation for a number of years. Taking people behind the scenes to watch planes move across a country on the voices of air traffic controllers was cool and something I miss.

    The layout in rural Manitoba has some neat animations. When you wow model railroaders it is another notch in my wire-wrap gun. It has been my sanctuary since retiring. My regular technology fix so to speak.

    Guided Backstage Tours - A Look behind the Scenes:

    Looks like a 1h tour of the North and 1 hour tour of the South is available but unfortunately not of the workshops.

    There is a bit about spouses here: Slight smile

    But I suspect most will prefer to go shopping and spend lots of money in the process, and then of course remind you about how you are more interested in your toy trains than in them, and before you know it you are outside a jewellers shop... 

    I thought that the animated building façade projection onto one of the model buildings was quite a nice touch.
