KNX Automation

KNX decentralized electrical automation system

Does not require each individually controlled unit to beconnected directly to a central control unit

Ease of installation, modifications become an ease

Excellent for industrial, commercial and homeautomation applications.

can be used to control anything ranging from roomlighting, room temperature and a security system

Energy efficient


5/28

ECTRO ENGINEERING

ECTRO Engineering's project aims to achieve some ofthese automation applications on a smaller scale

Create a mock house to demonstrate the KNXautomation system

Will include the automation of lights, a cooling fan,

blind shutters and a security system


6/28

Goal and research

Cater for most Australian modern homes or offices

Reliability and ease of use

Flexible options


7/28

Competitive Products

Work with already installed power circuits

Easy and affordable but limited control andautomation

Limited Security Features

Suffers from high overhead


8/28

C-BUS

Needs to be implemented during the

construction phase.Modules and implementation are very

expensive, runs for $15,000 AUD for a smallhome.

Better suited for commercial buildings to

take advantage of low voltage operation.

10/28

Research

Research based mainly on manuals

Have not yet had hands on experience with KNX modules

Problems that we have run into will appear in industry

Good experience as the project does emulate real life situations


11/28

Mitigation of Risks and Hazards

Hazards:

240 Volts 60Hz AC electricity

Mitigation:

Work on de-energized circuits.

Properly ground experiment and enclosure.

Never work alone, always have a partner who knows yourequipment and the risks and hazards involved.


12/28

Design

Major and minor specification changethrough out the first half.

KNX module Product Instruction books asmost reliable resource.

Product final specification based on theKNX module available through KNX lab.

KNX Bus Connection

Can connect switches sensors

Four channels

Power Supply

Energy Actu

Monitor Power, currenfrequency

Represent informationand store in log

Monitor power efficien

Supply the KNX bus line with30VDC for up to 64 modules

If significantly less modules are

used a second Bus line can beextracted as AUX 30VDC power.

KNX Modules

KNX Modules

DALI Light Controller

115VAC & 240VACoperation

Dimming function Up to 64 Dali devices

can be connected 8 inputs for ambient

light sensors

Dim Actu

Two channels Total power out 300W p

500W for a single chann Only loads of the same

on each channel eg: 240Halogen lamps


21/28

Four types of Bus available: Twisted Pair

Ethernet

Power Line

Wireless

Original specs designed for Ethernet

Current design for twisted pair

KNX Lab only has twisted pair with nowireless capability.

KNX Communication Bus


22/28

Software

Engineering Software Tool Version4 (ETS4)

Can create rooms and hallwayswith associated electrical actuators

Capable of creating commandsbased on sensor or forced inputs

Data must be transferredindividually through USB port andthe bus to each module

Can program multiple modules torespond to one input

Basic GUI programing
