Automation Architecture

5

Architectural Tenents

Able to withstand catastrophic failure – e.g. Fail safe doors. Able to withstand multiple service failures. Zero learning curve for Human Interfaces. “Reasonable” price. State of the Art and Beyond. Documented for repeatability. Rapid Recovery from catastrophic failure (ISO Images).

Wiring

7

Wiring – Cat6 “Copper’s last stand”

8

Wiring

Cat 6 for 10 Gigiabit Ethernet Backbone (Currently 100Mb) Cat 5e for Phone, IR Distribution. Shielded RG6 coax for Video. HDMI cables for Theatre. RF Relays between Dimmers. “Mesh” Network Dimmers. No “Daisy Chaining” No Cat 7 – New Connector – not RJ45

Managed Infrastructure

HAI Omnipro II Controller 8 PIR (Passive Infrared + Microwave) –to HAI 68 Windows – round inset Magnet - to HAI 7 Doors – round inset Magnet - to HAI @500 Lights, 130 Insteon Dimmers - to Mac 3 Cameras – Logitech, Apple, Sony - USB, Firewire, Cat 5e 8 Mike’s – via Shure Mixer - Toslink Minijack to Mac 1 RFID – Texas Instruments - RS-232-C to Mac 1 Phidget RFID Reader - USB to Mac iRTrans Infrared Controller. - to Mac TV’s, Music, Piano, Projector Screen - to Mac

12

Infrastructure – Computing

Ocelot (Applied Digital) low voltage switching (speaker & Mic switching Mac Mini - Primary Home Controller. Macbook - Development. iMac - Human Interfaces - Kitchen iMac - Human Interfaces - Office ThinkPad - Camera feeds to Mac. ThinkPad - Mouse Catcher & Camera feeds to Mac. PC - Athlon 64 bit. Windows, 8G, 2T – grunt work. (Deprecated) HAI Interfaces. MQ Interfaces. Music Server, Video Server. P390 - CICS WebService interfaces (Deprecated May 2008).

13

Wireless

2 x Apple Airport 802.11 n 1 x Airport Express 2 x Linksys 802.11 g 1 x Cantenna. Future. WiMax ZigBee Trick – give all the access points the same name and use the same channel number.

RFID

17

RFID Hardware – Radio, Antenna, Tags

18

RFID – how it works

19

RFID “Issues”

20

RFID Interface Coding (Applescript)

21

MySQL & Scripting Other Applications

22

Scripting Other Applications Remotely

23

Human Interfaces

24

Web Interfaces

25

Interfaces

iPhone (Safari, Mobile) Any Browser Any Phone Handset Voice Recognition Hard Wired Mic’s Voice Response V1 Female V2 Male & Female PIR Event (with Weight ?) RFID Events Camera Motion events

26

Services

27

Enterprise Services

Enterprise Service Bus – (Indigo Broker - AppleScript & Apple Remote Events for Messaging)

Monitoring

Security

JSON – XML-RPC SOAP

28

Internal Services

Door Camera Motion Service Door RFID Event Service Door Opened Service Door Closed Service Speak Weather Service Somebody Pressed the Doorbell Service Switch TV to view Camera Play Music Service(s).

Pub Services (Open etc) Goodnight Service Goodmorning Service Birthday Service Water the Lawn Service Open the Windows Service Close the Windows Service Play a Movie Service Mouse Down Service

29

Event Based Computing – Mouse Down

Metal Pad under Cheese – Soldered to 1 Wire. 2nd Wire Soldered to Spring Holder. Circuit Closes == Mouse Down Event. Video Taken by Evocam (last Video) sent to YouTube – Text Message to look at YouTube sent to iPhone.

e.g. Speaker Wire

Insteon EZIO.

30

External Services

NOAA – Weather (Free). Also Weather.com Change Sunset based on light level (sunny, cloudy etc). Control sprinklers – predict rainfall. Set variables for spoken responses. Google – GMAPs. Locate Family (iPhone Application – Objective ‘C’) Airline – Flight Scheduling. Heat and Light services at “odd” hours. eBay – “Snipe” Screen scaping to feed sniping service.

31

WMQ-Broker Usage – Deprecated

Interface between Mac’s and PC’s. – REST from PhP AJAX “Sometimes, good enough really is good enough” Interface to External Web Services. Interfaces requiring data transformation. PhP interface to Broker from Mac using REST Client for: Broker Web Service call to NOAA (Weather) parse response. Broker decides if it’s raining for Sprinkler via Timer Node. Broker makes web service call to Charter.net (what’s on TV).

32

Security

33

Security

Assume the worst. No DHCP. No broadcast SSID. Hard coded router tables. WPA. IBM Generated Passwords.

34

Security UPnP

35

Software & Shelfware

36

Shelfware

Evocam – Mac – 84% CPU Utilization. HAL 2000 - PC – Too Complex. XCode - Mac (except for iPhone) - PhP easier. WMQ Client for Mac - Only C Bindings - REST WMQ Server for Mac - Kernel Changes - REST RS-232-C Open Source PC - Too Complex. TI RFID Sample Code PC - Useless.

37

Motion detection CPU Utilization

38

Software

Indigo (ESB) Applescript Apple Remote Events Dreamweaver (Web, PhP) Photoshop Chicken of the VNC MAMP, WAMP Transmit (FTP) iRed Time Machine (Backup)

39

Lessons Learned

Most of the work you need for an SOA/ESB is building the INFRASTRUCTURE to support it. Adding Services is trivial once the Infrastructure is there. Swapping out services is trivial – e.g. Texas Instruments RFID to Phidget RFID Reader – about an hour. You need a development hardware environment and prod – trying to do it via VNC is like trying to swim through an ocean of Peanut Butter. PhP, MySQL, Apache, OpenSource is easy to write & use. Remember when programming was fun ? – it’s back.
