INTEGRATIVE DATA PROCESSING FOR CONNECTED CYBER-PHYSICAL OFF-SITE AND ON-SITE CONSTRUCTION

A major challenge to the aspired Co-Design approach is centralised data management. Although this challenge has been tackled from different perspectives in the past, utilising data models and formats from both building and mechanical engineering, it has not yet been resolved. The models represent the flow along the process chain. However, a backflow of information is outside the scope of most approaches.

This research project aims to address this shortcoming by creating a central data management platform with a standardised syntax and semantics that is shared across the entire process chain and supports interoperability between all stages, demonstrated by a co-design approach for an adaptive production system.

To identify the relevant data sources and formats, data acquisition is part of the requirements definition. Based on the results of this acquisition, we define the software architecture of the overall data management framework, along with its internal data model. We also incorporate semantics into the framework and devise appropriate interfaces for the relevant data formats. The data mapped into the central data management platform serves as the basis for algorithms that analyse the deviation of a monitored state from the anticipated state. This allows the implementation of a feedback loop to develop an adaptive production system.

This research presents a digital twin architecture designed to improve digital fabrication in the AEC sector. The architecture includes action modelling, virtual actor modelling, and service modelling, all coordinated by a central engine integrating a Cyber-Physical System (CPS) with its digital twin. The proposed approach standardizes data flow, integrates various fabrication methods, and supports rapid prototyping, tackling complexities in modern AEC environments. A case study from a Collective Robotic Construction (CRC) workshop demonstrates the architecture's practical application, showcasing its ability to streamline workflows, enhance scalability, and improve collaboration.

  @article{Ellwein_2021, abstract = {The term co-design describes a collaborative design process, usually across the boundaries of individual areas. A major aspect, and often an obstacle in the implementation of the co-design approach, is the establishment of a centralized data management system. In the past, the data management concept has been approached from different perspectives. Current approaches usually are oriented along the process chain and thus reflect a unidirectional flow of information. Neither the information feedback nor the reaction to adjustments in upstream model steps is supported, which makes continuous collaboration more difficult and at best reduces the co-design approach for continuous data usage. This paper addresses these weaknesses while outlining an integrative data processing concept enabling co-design between the domains of construction and industrial prefabrication. Geometrical information generated during architectural design and construction planning is reused for the production of components, manufacturing-related design adjustments are transferred back into the domain of construction. Changes throughout the entire process are centrally recorded. To ensure independence from the software tools used and to consider their great diversity, data exchange is largely based on standards, namely industry foundation classes and the standard for the exchange of product model data. In order to counteract the sequential processing according to a waterfall model and to support the co-design approach, the industrial prefabrication toolchain, consisting of computer-aided manufacturing software and downstream postprocessors, is largely automated, so that reprocessing of a workpiece for minor geometric adjustments no longer requires any interaction of the production planner.}, author = {Ellwein, Carsten and Reichle, Alexander and Herschel, Melanie and Verl, Alexander}, doi = {10.1016/j.procir.2021.05.103}, journal = {Procedia CIRP}, note = {31st CIRP Design Conference 2021 (CIRP Design 2021)}, pages = {451-456}, publisher = {Elsevier {BV}}, title = {Integrative data processing for cyber-physical off-site and on-site construction promoting co-design}, url = {https://www.sciencedirect.com/science/article/pii/S2212827121005746}, volume = 100, year = 2021 }

  @dataset{darus-4193_2024, abstract = {RabbitMQ GH is a Grasshopper plugin for implementing RabbitMQ messaging capabilities to exchange data between external applications and Grasshopper scripts in real time, with a high degree of flexibility and scalability. INSTALLATION Erlang installation Download the current Erlang version installer and follow the default setup in the installation wizard. Add Erlang to the Environment variables. To do it, go to Control Panel>System and Security>System. A new window will open. Click on Advanced system settings under the Device specifications collapsable panel. When the System Properties window appears, click on the Environment Variables button at the bottom of the Advanced tab. On the User variables section use the New... button to add a new variable with ERLANG\_HOME as the Variable name and the installation path as the variable value (By default the installation path should be C:\textbackslashProgram Files\textbackslashErlang OTP). To verify that the variable was correctly added, open a command prompt and enter the ECHO \%ERLANG\_HOME\% command. If the installation path is printed on the screen, the variable is correctly added. RabbitMQ installation On RabbitMQ´s GitHub page go to the Releases section on the right-hand side of the window. Click on the latest release and navigate to the assets section and download the rabbitmq-server-windows-.zip file, where corresponds to the latest release version number. Extract the compressed files to the directory where you want RabbitMQ to be stored. To run RabbitMQ, open a terminal window and go to the installation directory. Once there, run the rabbitmq-server.bat command. The current Erlang version and the plugins being used should be printed on the screen. In Windows, RabbitMQ does not run on startup by default. To change that, the Startup type of the RabbitMQ Server must be set to Automatic If the plugins are not working properly, follow the same procedure described in the following section to activate them. Management plugin activation To activate the management plugin, open a terminal window and go to the installation directory. After that, run the rabbitmq-plugins enable rabbitmq\_management command. This should enable the plugin and it should be working the next time RabbitMQ is launched. The same command works for activating other plugins by replacing rabbitmq\_management with the plugin's name after it has been downloaded into the plugin's directory located on RabbitMQ's installation directory. For further information, follow this link. Grasshopper plugin installation Copy the folder Installation\_Files/Rabbit\_MQ\_GH into your Grasshopper component folder. If you don´t know the location of this folder on your computer, you can find it using Grasshopper's interface. Go to File>Special Folders>Components Folder and a file explorer window will open in the correct directory. In general, downloaded .gha files can be blocked by Windows OS, so verify that all the downloaded files are unblocked. To do so, find each file in the file explorer and right-click on it. In the context menu select Properties. This will open a new window. Go to the lower part of the general tab and check the checkbox labeled Unblock. For the use of the plugin, even after closing the .gh files, the connections created in the session will remain open if the Run toggle is set to True. To prevent this, make sure to set the toggle to False before closing the file. Additional resources Linux machine deployment AWS deployment MANAGEMENT PLUGIN To open the management plugin, in your web browser navigate to localhost:15672 If no credentials have been established, use guest as the default username and password to log in. USE PATTERNS Example files covering several use patterns for Grasshopper, Python, and C\# are located in the folder Tutorial/Examples/. Most of them build on top of the consumer-producer pattern. It has two main components: A producer that sends messages to a RabbitMQ queue and a consumer that receives the messages from the queue and processes them. These are all the patterns covered in the example files with a detailed explanation in Tutorial/Examples/readme.md: Basic consumer Competing consumers Publisher-subscriber Request-reply Basic routing Topic routing.}, author = {Skoury, Lior and Wortmann, Thomas}, doi = {10.18419/darus-4193}, publisher = {DaRUS}, title = {Multi-protocol Messaging and Streaming Broker for Grasshopper (RabbitMQ_GH)}, url = {https://doi.org/10.18419/darus-4193}, version = {V1}, year = 2024 }
