With the continuous advancement of technology, Smart twin (Smart Building Digital Twin Implementation) has gradually become a hot topic in the construction industry. Many people want to know how to do it to truly implement this thing. In short, digital twins are to create a exactly the same digital replica for the smart buildings in reality. This replica can reflect the various situations of the building in real time and help us manage, analyze and optimize the operation of the building.
1. You need to make enough effort in the preparations in the early stage : you must first collect all kinds of data about the building, such as the design drawings of the building, equipment parameters, and data interface information of various sensors. Then, you have to choose a suitable digital twin platform. Different platforms have different functions and have to choose according to the actual needs of the building. For example, some platforms are good at energy consumption analysis, while some platforms do a good job in equipment maintenance and early warning.
2. The model must be carefully and comprehensive : the model is the core of the digital twin, so you must not be careless when modeling. The structure, equipment layout, pipeline direction and other buildings should be accurately presented in the model, and it is best to accurately reach the specific model and installation location of each device. Moreover, the model must be synchronized in real time with the actual building, so as to ensure the accuracy of the digital twin.
3. Data connection is a key step : there are various systems in the building, such as HVAC systems, lighting systems, security systems, etc., and the data of these systems must be connected. Let them transmit data to the digital twin platform in real time, so that the platform can summarize and analyze the data and discover problems in a timely manner. For example, if the temperature in a certain area is abnormal, the platform can immediately find the problem by analyzing the data.
Q: What are the easiest difficulties to encounter in the implementation of digital twins?
A: The most easiest thing to encounter is the problem of data inconsistency. Because the equipment and systems in the building may come from different manufacturers, their data formats and interface standards are different, making it difficult to unify the data. To solve this problem, you need to formulate unified data standards or develop middleware to convert data in different formats .
Q: What practical help does digital twins have to manage energy consumption in buildings?
A: It’s a lot of help! Through the digital twin model, the impact of different operating schemes on energy consumption can be simulated, thereby finding the optimal operating strategy. For example, simulate the changes in the energy consumption of the building under different temperature settings, and then choose the most energy-saving temperature control plan to achieve the purpose of reducing energy consumption .
During the implementation process, the compatibility and scalability of the platform must also be considered. After all, the building needs to be used for a long time, and new equipment or systems may be added in the future. The platform must be able to support these expansions, otherwise it will not be used in two years, which will waste more money. And it cannot be too complicated to operate, otherwise no one will use it, and the digital twin will lose its meaning. Provide global procurement services for weak current intelligent products!
Personally, although Smart twin may have a large investment in the early stage, in the long run, it can bring great benefits to efficient management of buildings, energy conservation and consumption reduction and safe operation. It is an inevitable trend in the future development of smart buildings and is worthy of trial and promotion by friends in the construction industry.
