1. Creating a completed control system
Lesson 5&6
Creating a completed control system

2. Lesson Objectives
To understand that working control systems contain many flow charts that work alongside each other
To apply flow chart knowledge when creating a working control system

3. Control Technology in everyday life
Think about a control system that is used every day.
How many different inputs and outputs can you name?

4. Example Burglar Alarm Input Output Senor on window
Movement sensor in every room
Pressure sensors
Lock sensors
Output
Sound alarm
Flashing lights
Automatic response from police

5. Working Together
All of these inputs and outputs are controlled with a complex system of flow charts.
Over the next 2 lessons you will be using the train mimic to simulate a realistic train route

6. There are various trip points around the track
There are various trip points around the track. We can use this to sense where the train is.
What might happen when the train reaches A?
What might happen at trip D?

7. Step 1: Making the train move
Input 1 will act as a button. When we press it the train will move forward.

9. Step 2: Opening and closing the barriers.
In the simulation there are several trip points. These are sensors which sense when the train is passing
Which trip point should we use to sense if the train is on its way?
Which trip should we use to sense that the train has passed the crossing?

11. Step 3: Slowing at the platform
A train slows down every time it goes through a station, even if it doesn’t stop.
We can slow down the motor using the trip points

13. Step 4: What important part of the train simulation are we missing?
There are a number of things that we can do in order to improve it.

14. Extension Open the mimic called Train Set 2.
But there are lots of differences. 2 more trip points and another train to control!
Open the mimic called Train Set 2.
There are many similarities including the barrier tunnel and trip points
