Digital transformation topic is not uncommon, almost every day there are new topics appear, of which the digital twin is also a no stranger topic, but always able to bring you a sense of mystery and freshness, when the plane comprehensive visualization can not meet the basic requirements of digital transformation or the vision of the enterprise, the digital twin - 3D integrated visualization platform came into being, to bring enterprise units a more intuitive understanding of enterprise status information, can quickly make countermeasures, shorten the operating time. Reduced operating costs...

Digital twins are common, but few can explain them clearly. Digital twins from the "Digital Twin", by Professor Michael Grieves in the United States when teaching at the University of Michigan first proposed, the word of digital twins is hot in recent years, in fact, has more than ten years of history, the initial digital twins applied to the aviation field, in order to record the operating state of each aircraft engine, gradually extended to the aircraft geometry mode, fuselage material performance data, flight test data, inspection and maintenance data, inspection and maintenance data, Enterprise dynamic model data, finite element model... And so on, and later gradually widely used in the industrial Internet.
"Twin" generally refers to twin siblings, the characteristics of twins are very similar, almost exactly the same; "number" refers to all objects in the form of numbers, whether static or dynamic, whether animals or objects, whether real or virtual, their forms and state forms are expressed in the form of numbers, can intuitively understand their real state information. Digital twin refers to the effective combination of physical body and virtual body, the real state data of physical body will be synchronized on the virtual body, time, can support real-time synchronization, but also support real-time synchronization. The virtual-real mapping correspondence of the digital twin is not just one-to-one, it can be "many-to-one", "one-to-many" or "many-to-many"... And so on.

With the wave of digital transformation and upgrading, China's industrial manufacturing has developed to a high degree of automation and informatization, generating a large amount of industrial data in the production process. Due to the heterogeneous and dispersed nature of the data, it has not exerted potential value in industrial production. Based on the real data of the production process, the industrial digital twin creates a virtual digital world for the physical objects in the industrial production process, and maps the various parameters of the physical equipment to the virtual body of the virtual digital world, so as to realize the virtual and real integration and accurate mapping of the industrial physical factory and the virtual factory. Factory managers view, analyze, and manage the entire plant's production process through a virtual twin space to accurately locate abnormal problems to help optimize resource allocation. At the same time, driven by real production data, the synchronous operation of factories' production factors, production activity planning, production processes, etc. in the virtual twin space is realized, and the optimal production operation mode of factory production and control is assisted.
<h1 class="pgc-h-arrow-right" data-track="21" > the advantages of digital twins</h1>
Digital Twins is a high-tech technology that uses digital means to build a digital world similar to a physical entity through 1:1, and to study, analyze and predict the entity through digital avatars. Thus achieving the following purposes:
1. Improve product quality index: through predictive analysis, improve and optimize the product production process, reduce the product error rate, solve product quality problems, and achieve accurate strikes on product problems.
2, reduce the cost of operation and maintenance: digital factories need to conduct regular detection and statistical analysis of the factory system, electrical equipment, water equipment, refrigeration equipment... And so on equipment maintenance planning, reduce O&M costs.
3, improve efficiency and productivity: through the digital twin technology, each production process will be transparent, easy to find the advantages and disadvantages of the process, easy to optimize rectification and management upgrades, thereby improving efficiency and productivity.
4. Rapid response to emergencies: Digital twins can quickly display the location and specific conditions of emergencies, and at the same time prompt relevant staff to respond to measures, reduce the loss of breakthrough events, and improve the practical ability of employees.
5, easy to use and innovation: the operation that can not be implemented in the physical entity on the digital virtual body, you can get the operation to increase the production capacity, improve the innovative thinking of employees.
6. Combination of virtual and real: the combination of virtual body and physical body, real-time synchronous data, can accurately overhaul the equipment, accurately check the problem equipment, and quickly inspect the real-time status of the equipment.
7. Analysis and prediction: Through the data collection of the Internet of Things, according to the transmission, screening, analysis and management of data, the physical body can be predicted, which effectively reduces the occurrence of breakthrough events and improves the safety production coefficient.
<h1 class="pgc-h-arrow-right" data-track="22" > the application field of digital twin is very extensive, widely used in industrial manufacturing, aerospace, smart parks, smart municipal, water conservancy transmission, power transmission, natural gas, oil transmission, auto parts, photovoltaic...
