Agenda• Business Opportunities and Challenges

• AQUASI ‐ the research project

• Cloud and Edge node management

• The AQUASI data and communication model

• The AQUASI language


Business Opportunities

• „green and sustainable“ technologies become more and more important


The product of NUR‐HOLZ

• Sustainable green houses– production of massive wooden wall elements– made of “wood‐only”

• without any glue, chemistry, metal, …

wall elements produced in 2‐3 dayshttp://www.hur‐holz.com


The „green“ Office Building

• built in the Netherlands

– certified by BREEAM as the most sustainable Office Building worldwide

– 99,94% sustainability


The SME Business Challenge• handcraft industry is going industrial production

– fraction of pre‐assembled products grows– but: handicraftsmen are still committed to quality

• a local SME goes out to the world– house are sold in Baden‐Württemberg, Germany, Switzerland, Italy, Netherland, Norway, Japan, …

– collaboration with partners worldwide is required

• there is still resistance to green technology– prove that the house lasts long enough


Industrie 4.0• Targets

– horizontal digital integration of engineering in value networks

– vertical integration of networked manufacturing systems

– improvements in production process and product quality

• Versioning reminder1.0: mechanization• „Steam engines“

2.0: industrialization• „Production line“

3.0: automatization• „micro controller “

4.0: computerization• ???


IT challengesCloud Computing infrastructure

• services for Computing, Storage, Network • used by

• many large companies• many IT startups

• but not used by • SMEs with little IT staff

Internet of Things

• Connected sensors will deliver information about the real world

• Connected actuators will be controlled by „smart“ systems

Cyber Physical Systems

• combining both approaches• enable analytics to extract knowledge• generic for application domains

Cognitive Systems


The AQUASI Business Drivers (I)

• Deliver a Quality product– within a scalable worldwide partner network


The AQUASI Business Drivers (II)

• Deliver a Quality product – over the whole product life cycle

• a few decades

– use modern IT technology to improve quality• Cloud, Sensors, IoT, BigData, AI, Wearables, … • but the core competence of the company is “carpantry”

CONCEPT DEVELOPM. PRE‐SALES PRODUCTION SALES & DISTRIBUTION

QUALITYASSUR.

max. 1 year > 70 years


Sensors• Quality assurance need data • use

• Smart Home data– i.e. : temperature, air humidity, …– look at the environment

• Image data– i.e.: High definition camera– look at the surface of the wall

• micro sensors– i.e. : Temperature, moisture– look into the walls

» possible due to the EM propertiesof wood and the production process(stack plank construction)


The AQUASI Project• performed by DHBW Mannheim

– Duale Hochschule Baden‐Württemberg – (Cooperative State University of Baden‐Württemberg)

• in collaboration– with Rombach NUR‐HOLZ, Oberharmersbach– and teXXmo, Böblingen

• funded by Baden‐Württemberg Stiftung– http://www.bwstiftung.de/

• for 3 years started in 2016


Goals of the AQUASI system• systematic collection and preparation of all construction and planning

data for a house building project

• IT support for (external) construction teams at straightening

• continuous acquisition of sensor data from all wooden houses with the help of networked sensors

• recording of annotated pictures and artefacts for quality control

• remote maintenance of sustainable houses in interaction with localpartners and production experts in the SME

• Continuous analysis of the data in order to detect abnormal qualitysituations like failings, shortcomings or design imperfection


AQUASI approach• use existing and proven technologies

– Solid Open Source eco systems• Software from the Eclipse Foundation

– JAVA with OSGi for Cloud and Sensor runtime

– REST architecture with HTTPS/JSON for transport

– X.509 Certificates for security and privacy • with JWS (Json Web Security)


Cloud and edge nodes• worldwide distributed

– desktop UI at partnerenterprises

– Sensor Gateways in Houses

– mobile devices

– one centralized AQUASI Server (in Cloud)

– Cloud Storage Systems

– many analytical Services (in Cloud)


Overall architecture


Managed Software Provisioning


Demo Part One• Manage Cloud and Sensor nodes

• Please note: Everything is work in progress und under construction


Project Domain model I


Project Domain model II• Based on micro‐services

– “house project” is the center of the system • domain data are distributed in edge nodes

• the AQUASI Server connects these data – by providing data and links

to children– use the Composite Pattern

– “partners” are independent of projects• important for any “house project”

https:// [AQServ]/services/projectshttps:// [AQServ]/services/projects/[id]https:// [AQServ]/services/projects/[id]/partnershttps:// [AQServ]/services/projects/[id]/offeringshttps:// [AQServ]/services/projects/[id]/ConstPlanshttps:// [AQServ]/services/projects/[id]/ConstPlans/[EtageID]/https:// [AQServ]/services/projects/[id]/ProduPlanshttps:// [AQServ]/services/projects/[id]/Imageshttps:// [AQServ]/services/projects/[id]/Sensorshttps:// [AQServ]/services/projects/[id]/Statushttps:// [AQServ]/services/projects/[id]/Dateshttps:// [AQServ]/services/projects/[id]/Events

https:// [AQServ]/services/partnershttps:// [AQServ]/services/partners/[id]https:// [AQServ]/services/partners/[id]/contactshttps:// [AQServ]/services/partners/[id]/contacts/[cid]


Project Domain model• All project artefacts are “AquasiComposite”s

– AquasiComposites are fine‐grained services• contains the links (AquasiDescription) to the children • i.e. the JSON response to a project

{"desc":{"name":"House 42", "remoteUri": "https://AQServ/services/projects/42"}, [{"name":"Partner", "remoteUri": "https://AQServ/services/projects/42/partners"}, {"name":"Status", "remoteUri": "https://AQServ/services/projects/42/status"}] }


AQUASI communication model

• Example of access to the fine grained services– access to AQUASI project and partner services


AQUASI communication model• Example of access to the fine grained services

– exemplary access to Cloud service• here: accessing to a pdf stored by a cloud provider

– Cloud Storage service offers a REST interface


Demo Part Two

• Prototype for NUR‐HOLZ Domain – Partners– Projects– Sensors


The Platform• AQUASI platform will delivers basic functionality

• https://AQUASI.server/services/certs• https://AQUASI.server/services/users • https://AQUASI.server/services/cloud

• Each SME adapts the domain services to their service needs – in the case of NUR‐HOLZ

• https://AQUASI.server/services/partners– including subservices

• https://AQUASI.server/services/projects– including subservices


The i40 domain language

• we started with simple DSL– based on AQUASi data and communication model

– to enable other SME domains to deliver services • in high quality• and in short development time• for more platforms than just E4

– Android, UWP, HoloLens

– using Eclipse Xtext project• (Thank to the community!)


Demo Part 3

• Xtext Language– very early stage example

– we used the language for the development of the„/cloud“ services and some UI composites already


Our vision• OSGi in the center of the app, in the cloud and on the edge nodes

• simple management of the AQUASI product cloud– even for SMEs

• Collected Data and analytics will help to answerquestions like: – How can I construct a wooden house on Hawaii using a blueprint of a house in Norway?

– How can I control the house heating optimal? – …
