Requirements for HCNMS

HCNMS stands for Home Control Network Management System

High level requirements easy monitor, control, and configuration support LonMark Guideline iLon Functioning secure HCNMS

Lower level requirements well-defined functional APIs as a device service platform observing LonMark Interoperability Guideline abstraction and representation of application devices supporting zero-configuration compatible with LonTalk network management protocol OSGi compatible packages


Scope of HCNMS

Environment of R&D Linux, x86 processor?, C & Java

Basic Technologies LonWorks : LonTalks, Neuron Chip

Target Application Devices Sensor Network

Temperature, Infrared sensor, Curtain, Lights, Various-meters…

Appliances ?? Refrigerator, Air Conditioner, Washing Machine, Microwave, Fan,…

Target Services iLon functions easy configuration service for end users


Architecture of HCNMS (1/2)

① connect web server (at home server)

② show home page and do authentication

③ choose a device which client want to control or monitor

④ send an applet appropriate to the device

⑤ fork an servelet which communicates with the sent applet

⑥ run the downloaded applet which provide appropriate control or monitor interface

⑦ control or monitor using the user interface at applet

⑧ transfer the user request to HCNMS

⑨ return the result to clientClient

Example of Device Pool



Easy Configurator ScenarioI. Initialization of Lon Network

detecting all the devices at home gathering properties of all devices

II. Device Abstraction DA (Device Abstractor) abstracts detected physical devices into

logical devices in the device pool

III. Service Generation SG (Service Generator) generates all the possible service with the

combination of the abstracted devices then, SG puts the generated services into the Service DB

IV. User configuration programming user programs through the GUI (drag&drop) select services from the possible service list

V. Program Interpretation Program interpreter translates

service into a sequence of Lon Messages

VI. Configuration use APIs of NM core module

Summary

it’s brief design of functional specification of HCNMS. we should develop followings..

Considerations

Further Studies Device Abstraction Guideline Bluetooth-based control network

What middleware will be the winner at home? Can those integrated into one Service Platform? Where the IP will be deployed into at home?

IP over IEEE1394 IP over Bluetooth (ongoing by IETF BOF) IP over PLC ?
