Thinking about digital twins

digital twin

source

In 1991, David Gelernter published Mirror World, which first proposed the idea of digital twin technology. However, Dr. Michael Grieves (who later taught at the University of Michigan) first applied the concept of digital twins to manufacturing in 2002, officially announcing the concept of digital twin software. Eventually, NASA's John Vickers introduced a new term "digital twin" in 2010.

But in fact, the core idea of using digital twins to study physical objects has emerged earlier. In fact, it can be said that NASA pioneered the use of digital twin technology in space exploration missions in the 1960s, and each spacecraft has an exact replica version left on Earth for NASA personnel to study and Simulation in order to serve the crew.

meaning

Digital twin is to make full use of physical model, sensor, operation history and other data to complete the mapping in virtual space, so as to reflect the life cycle process of corresponding real physical equipment. A digital twin is a concept that transcends reality .

Summary: In today's world, I think it's achievable

working principle

A digital twin is a virtual model used to accurately reflect physical objects. Objects under study (eg wind turbines, factories, drilling rigs, aircraft, etc.) are equipped with various sensors related to important functional areas. These sensors generate data related to the performance of different aspects of physical objects, such as energy output, temperature, weather conditions, and more. This data is then forwarded to a processing system and applied to a digital copy.

Once this type of data is obtained, the virtual model can be used to run simulations, investigate performance issues and generate possible improvements, with the ultimate goal of generating valuable insights - which in turn can be applied to the original physical object.

Summary: The sensor is used to transmit the data model to the processing system, and the processing system generates a digital portrait, and the ultimate value is infinite

Application scenarios

• power generation equipment
• large physical structure system
• manufacturing
• medical service
• Transportation Industry
• City planning

future

Digital twins have a limitless future! With the help of the following video, we can imagine

It can be extended to the thinking of specific scenarios, inserting sensors into the hardware, capturing data of the action module, passing the data to the background, reading the data in the foreground, rendering on the interface, and interacting on the hardware for real-time data transmission, the foreground can Is it cool to see the action interaction in real time? At present, this idea has a simple implementation in some construction companies, such as indoor large-screen visualization, simple opening and closing of blinds, etc.

It can be viewed in two dimensions, one is the physical world and the other is the digital world . The barriers between the two are opened up through sensors. The difference with the metaverse will also be discussed below.

Web3.0

source

Web3.0 is a concept about the development of the World Wide Web, mainly based on the decentralization of the blockchain, cryptocurrencies and non-fungible tokens. The concept of Web 3.0 related to blockchain was proposed by Ethereum co-founder Gavin Wood in 2014, and in 2021, it has attracted the attention of cryptocurrency enthusiasts, large technology companies and venture capital firms. In addition, it was suggested that Web3.0 related to Web2.0.

meaning

Here is a brief description of my understanding of it. In the Web3.0 era, the information on Wanwei can directly interact with other websites, and use the characteristics of the blockchain to complete the reading, writing, tamper-proof, and decentralization of information. It breaks through the industry barriers formed with today's major Internet companies and accelerates the development of information. Users' data is completely owned by themselves. For a simple example, your information on WeChat is stored on Tencent. not in your own hands. So Web3.0 was born to solve this problem. In the era of Web3.0, there are no longer landlords, but all farmers based on "consensus", collectively open up a new piece of land. On this land, everyone has Property rights, according to their own contributions, such as whether they have participated in land reclamation or farming, or whether they have carried out watering or harvesting, including the final storage, buying and selling, as long as they contribute to the entire production process, they will receive benefits according to the corresponding contribution value. This is the ideal state of Web3.0, which is beneficial to every citizen of the Internet, which is the so-called Internet Utopia

evolution

Web1.0 -> Web2.0 -> Web3.0

Web1.0

The information is read-only, which means that users can only browse the content provided by Internet companies. You have no ability to interact or modify. All capabilities are provided to you by the platform, and you can only view them.

Web2.0

Information can be interacted or modified. Content creation is generated by users. Content distribution, control, and revenue distribution are controlled by the platform. This is the so-called platformization.

Web3.0

De-platforming, that is, content creation, publishing, control, identity, and revenue, are all determined by users

future

Analyzing the disadvantages of Web1.0 and Web2.0, understanding what problems Web3.0 is to solve, and how to develop it later, I personally think it is too ideal

NFT

meaning

The full name is Non-Fungible Token, which refers to non-fungible tokens. It is the only cryptocurrency token used to represent digital assets (including jpg and video clips). The design principle is that it can be bought and sold.

Summary: NFT can be understood as a type of scenario application of blockchain technology

Application scenarios

blockchain

source

The blockchain originated from Bitcoin. On November 1, 2008, a self-proclaimed Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, time The architectural concept of the electronic cash system of stamp technology, blockchain technology, etc., which marks the birth of Bitcoin. Two months later, the theory entered into practice, and the first genesis block with serial number 0 was born on January 3, 2009. A few days later, on January 9, 2009, a block with serial number 1 appeared and was connected with the genesis block with serial number 0 to form a chain, marking the birth of the blockchain.

meaning

The blockchain in the narrow sense is a chain data structure that combines data blocks in a sequential manner according to time sequence, and is an untamperable and unforgeable distributed ledger guaranteed by cryptography. The generalized blockchain technology is to use the block chain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, use cryptography to ensure the security of data transmission and access, and use smart contracts composed of automated script codes. , a new distributed infrastructure and computing paradigm for programming and manipulating data.

Summary: Web3.0, NFT, Metaverse, the transaction guarantee of the underlying logic, provide the possibility for wallet (identity)

metaverse

source

The term metaverse was born in the 1992 science fiction novel "Avalanche", which depicted a vast virtual reality world in which people were controlled by digital avatars and competed with each other to improve their status, and by now, the description The future is still ahead of the world. Regarding the "metaverse", the more recognized source of thought is the American mathematician and computer expert Professor Verno Vinch. In his novel "Real Name" published in 1981, he creatively conceived of a brain-computer interface to enter and Get a virtual world of sensory experience.

Summary: From the first science fiction novel "Avalanche" in 1992, to the film "Ready Player One" published by Steven Spielberg in recent years, all of them expound a concept, that is, to enter the virtual world through an interface , and ultimately to Solve one of the core problems, how to make humans have the same touch , even physical experience

meaning

The metaverse is a virtual world that maps and interacts with the real world, a digital living space with a real social system.

Summary: Essentially anything you do in the real world is theoretically achievable in the Metaverse

Application scenarios

• encrypted digital certificate
• Web3.0
• VR/AR/MR

Here we will focus on the differences between Web3.0 and the Metaverse. Web3.0 can be understood as an industry expression, and the Metaverse is the public expression of the next-generation Internet. The difference between the two is not very big in essence.
