Delta Smart HouseControls Infrastructure Team

• Final Presentation

2
Problem

• To build a controls infrastructure that is
  capable of handling the communications needs of
  the house
• Must handle information transfer among devices on
  the network in a timely and efficient manner
• Must be robust enough to easily add a new device
  to the network

3
Semester Goals

• Become familiar with the Echelon network and how
  it works
• Read documentation
• Hardware demo
• Design the layout for a small demo room
  consisting of approximately 5-6 devices

4
The Hardware Demo

• Echelons basic Getting Started package
• 3 LonPoint modules
• AI-10, AO-10, DIO-10
• iLon 100 Internet Router
• LonMaker software package

5
Commissioning Devices

• Use of LonWorks Plug and Play control panel
• Commissioning devices by pressing service pin
  transmits modules unique Neuron ID to the
  network
• Basic network layout in Visio

6
Initial Network Setup

• AI-10 module acts as a temperature sensor,
  receiving an analog input that represents
  external temperature
• AO-10 outputs the temperature of the room to the
  AI-10 module
• DIO-10 switches on and off either on a given time
  interval or in response to external conditions

7
Settings

• Default values can be set in LonMaker program
• Easy to change behavior of LonPoint modules
  through Visio interface by changing settings of
  each device

8
Addition and Customization

• Interface with the internet through iLon 100
  internet router
• Ability to program custom behavior using
  Echelons Neuron C programming language, derived
  from ANSI C
• When clause allows for event-driven execution

9
Demo Room

• 8 devices and internal controllers
• Heating, cooling, and lighting systems for a
  bedroom
• Devices receive analog and digital inputs from
  environment
• Internal controllers use environmental variables
  and internal decision schemes to change state of
  device and send outputs

The Layout
11
Lighting Devices

• Devices
• Blinds
• DI 1 to open blinds, 0 to close
• DO 1 if open, 0 if closed
• Desk Lamp
• DI 1 to turn on lamp, 0 to turn off
• DO 1 if lamp is on, 0 if off

12
Lighting Controller

• Inputs
• Alarm clock
• Digital 1 if alarm goes off
• Analog Time
• Status of blinds and desk lamp
• Decision Scheme
• Open blinds when alarm goes off
• Close blinds at a set time
• Close blinds if light is on

13
Heating and Cooling Devices

• Ceiling Fan
• DI 1 turns fan on, 0 turns fan off
• DO 1 if on, 0 if off
• AC Unit
• DI (2) 1 turns on AC, other turns on heat
• DO 1 if on, 0 if off
• Temperature Sensor
• AO Temperature

14
Heating and Cooling Controller

• Inputs
• Temperature Sensor Temperature
• Status of AC unit and ceiling fan
• Decision Scheme
• If temperature is slightly above desired, turn on
  ceiling fan
• If temperature is below desired, turn on heat
• If temperature is slightly above desired, turn on
  AC

15
Humidity

• Humidity Sensor
• AO Humidity
• Humidifier
• DIO 1 if on, 0 if off
• Basic controls scheme
• If humidity is too low, turn on humidifier
• If humidity is too high, turn on ventilation

16
Future Plans

• Find controllers and devices that would be
  feasible for creating the demo room
• Expand list of devices if necessary
• Become more familiar with Echelon network
• Incorporate iLon 100 internet functionality

17
Long-Term Goals

• Design and implement demo systems for each room
  of the house
• Provide support in the form of documentation and
  personal experience to help other groups
  interface their devices with the LonWorks network
