  1. hello as a masters student currently I'm doing my thesis related to digital twin, and I just proposed a cloud based tool that can control and monitor IoT device through cloud using BIM Model File. I've tested the tool and it is now working but my worry is which standard or ontology that states the relation between BIM and IoT device specially for Controlling? thanks in advance
  2. Morning All, Currently investigating a case for a Digital Twin concept - is there any guidance relating to the structure of the data to align up to a more national structure? Any useful guidance to help the beginnings of this case move in the right direction? Thanks, Lewis
  3. Predicting the future is something intrinsic to the human condition. Whether we are thinking about lunch, retirement, or developing a world-shaking invention like the iPhone. What if the biggest barrier to realising the potential of innovation is not technology, but belief? Predictions of the future from the 1950s included people flying around in their own helicopters to do their daily chores. Ignoring the acceptability of helicopters powering up and blowing the contents of everyone’s gardens everywhere, this future could have happened. There is no technological boundary to everyone having a helicopter in their garden or on the street. However, it was believed correctly that flying machines are extremely dangerous and that their ownership and piloting should be rigorously controlled. That then, is why that idea never took off. It may be tempting to scoff at this suggestion entirely, but there are now several places only accessible by plane and even a housing estate in Florida where every resident owns a plane as their primary means of transportation. If you would like your own home with an attached hanger, check them out here. The motor vehicle faced very similar push back from the populace and the media when they were introduced. They were smelly, loud and dangerous, not to mention costly. However, once the car had been accepted as an ordinary part of everyday life, the risk increased as they became faster. Cars were now so intrinsically embedded in our society that the idea of removing them had become unconscionable. Digital twins will undergo the same process of becoming publicly acceptable as the question of risk continues to arise. The idea of a building or a motorway self-managing might seem like a stretch to the layperson, but this has already begun with Building Management Systems and Smart Motorways. It is important that we acknowledge the ability of these systems to fail and make sure that we have integrated fail safes that perform the equivalent role of airbags in cars. Similarly, the idea of the smartphone underwent a similar process of becoming acceptable to the general public not so long ago. They were already present in our society when the iPhone was released, but it was the iPhone that made the concept of the smartphone mainstream. Was it that the technology was superior? In part perhaps. What really made the difference was that Apple sold us a lifestyle choice. That narrative around the iPhone, its versatility thanks to the app store and its good looks were what really made the difference. The technology already existed, but it had never been brought together effectively as a whole product. The app store enabled owners to customise their experience and created a platform for services that today is worth billions of dollars. The Digital Twin is to the Internet of Things what the iPhone was to the smartphone. The concept of connecting things to the internet makes sense and smart speakers and smart devices have had some success. However, the concept of the internet of things is nebulous at its core. Its story raises questions, we connect things to the internet. That’s it. It’s up to the developers of technology to take that idea and turn it into real products. You cannot procure an internet of things; you cannot own one. A digital twin however is procurable. It is also neatly definable to the layperson. You have a physical asset and a digital representation of that asset; these twins communicate with each other so that you can manage your assets more effectively. You can see the digital twin, make changes to it and they happen in the physical twin. This simplicity of narrative is exactly what sold the first iPhone. Your email, music, calls and the internet are all in one place. It’s a very simple idea to communicate despite it being a very complex product. If you compare this sales pitch with the O2 XDA, the rival smartphone at the time, you see a focus on technical specifications. The advert did not answer how this product will make your life easier or better, instead it focused on power and speed, which for an enthusiast (such as myself, who owned an O2 XDA) is very enticing, but for the wider population made little or no headway. It is the narrative of the Digital Twin and the National Digital Twin that makes the difference, having prepared the groundwork for public acceptability with the Gemini principles of purpose, trust and function we have learnt the lessons of the past when adopting an innovation so that we do not need to sacrifice the individual’s rights and safety for the general public good as we did for cars. Similarly, with the story of the National Digital Twin we have learnt the lesson of the iPhone, that innovation must be tailored to people’s lifestyles, that is not simply a technology for the sake of it, but something that will enhance our lives in an easily understandable way. We have a challenge then, if the brand is as important as the technology, how do you think Digital Twins should be marketed? What should be the story we tell?

    Demonstrator project

    One for the calendar :- we recently did a demonstrator project with Microsoft’s Azure Digital Twins team for the Build Conference which will be featured as a Deep Dive on Microsoft’s Channel 9 IoT Show on August 3rd. https://channel9.msdn.com/Shows/Internet-of-Things-Show/Deep-Dive-Integrating-3D-Models-and-IoT-data-with-iTwin-and-Azure-Digital-Twins In this session we will demonstrate an application that combines 3D models, 2D maps, and reality mesh into a single environment for visualisation Within that environment we will demonstrate a live, real time, seamless visualization of IoT data streams. Next we will walk through the architecture that enables the application. We will show how we have mapped the IoT data to the assets within the digital twin. And we will show how to keep the digital twin in step with engineering changes. This is done by automating the generation of the Digital Twin Description Language (DTDL) .JSON. Bentley's iTwin platform and iModel.js open-source programming library provide powerful capabilities for aggregating 3D, 2D, reality data and other sources to link with IoT data for a "single pane of glass" visualization, analytics, and simulation so users can make more effective decisions in a timely manner. By integrating the iTwin platform with Azure Digital Twins and other Azure IoT services, Bentley and Microsoft are making it easier for developers, integrators, and customers to build digital twins of their infrastructure assets. It would be great to get feed back from as many as possible once the show has aired
  5. I'm thinking of promoting our HE Ontology in the hopes of a) being able to explain to normal people what we're doing (and why) and b) hopefully securing some interest and feedback from the wider community and ideally other road operators. It's also been a useful opportunity to condense and reiterate to myself what on earth I've been doing with my life. Anyway, before I fire this into the ether, I thought it might be useful to get some feedback. The draft article is here should you be interested... https://www.linkedin.com/pulse/draft/AgGQLPmRvH_kkgAAAXMLChJcc3Cpv-7oz99HbLpUZI7xX7d0XAb4vwRXGvs2CeEVWQ8VnAE Thanks in advance!

    Digital Twin and IoT

    Sort of 2 questions What piece of IoT kit would make your Digital Twin more effective What IoT have you found that transforms your knowledge of business (helps you build a better DT) So what IoT would you like, what have you found/used?

    DTs for Smart Cities

    This webinar may be of interest from Smart Cities World: Leverage digital twins to optimise municipal operations Find out how Gwinnett County (USA) is unifying IT/OT/IoT systems to provide complete visibility to all municipal data. Using a Digital Twin of their municipal operations allows faster, more informed decisions and speeds crisis response while lowering their total cost to operate their services. https://www.smartcitiesworld.net/webinars/webinar-centralized-command-and-control-of-multi-site-municipal-water-operations
  8. Aerospace was one of the first industries to develop digital twins. This academic paper helps to identify the initial research papers around the concept, and the scope of Digital Twins within several sectors as they emerged https://www.sciencedirect.com/science/article/pii/S2351978917304067
