Description

Technical Field

[0001] The present application relates to the field of virtual reality technology, and in particular to a three-dimensional modeling space simulation system and method for smart buildings. Background Art

[0002] Architects and engineers use BIM to represent the structure so that there is a construction plan that shows where the flaws in the building plan are and any changes that need to be made. 3D modeling is an important step at the beginning of a project because it saves the architect from having to redesign something that doesn’t work in the real world, which wastes materials and time for the builder and the people who pay for the construction project to build something that doesn’t work.

[0003] But this isn’t the only way 3D modeling is currently being used in construction. 3D modeling can be used to demonstrate to clients, builders, or anyone who needs to know that a project has been built to spec. Verifying a construction project from an architectural 2D plan can be difficult, but a 3D model can prove that the plan has been followed and the design is accurate. Virtual reality can make this even more accurate and easier to observe.

[0004] The virtual reality system can provide such an opportunity for our architects. Using the virtual reality system, architects can use it as a tool for evaluating building performance, discovering defects in building design, and use the system to simulate different solutions to the problems, thereby improving the design of construction projects at a very low cost.

[0021] Among them, in this embodiment, by developing special hardware, various BIM data of the real environment are obtained, and the control variable method is used to design comparative experiments, and a set of BIM data correlation filtering suitable for replaceable building materials is studied, and the data correlation algorithm of the software system is designed through filtering.

[0022] The most important data is temperature data. Since there are many factors that affect the temperature change of the intervention material and there is no direct linear correlation with the light intensity, it is difficult to accurately reflect the actual data by relying solely on algorithm simulation.

[0023] In order to ensure the accuracy of the simulation effect, the real-world BIM data is obtained by various sensors installed in the hardware system. The integrity of the data should cover as many scenarios as possible based on time and seasonal changes. The completion of this work requires a large amount of sample collection and experimental comparison.

[0025] At the same time, a special algorithm is developed for the UE plug-in to convert the lighting on the building surface into visual thermal infrared characteristics, which makes it convenient to directly observe the lighting status of the building surface in UE with vision.

[0026] The plug-in needs to be packaged into a dynamic library, and the dynamic library needs to be copied to the directory specified by the UE system file. You can load the plug-in by re-running and loading the dynamic library.

[0028] Among them, in this embodiment, by developing a software system, the simulation data of the UE plug-in and the parameter data of different building materials are associated, and the corresponding BIM data is analyzed and calculated and displayed in conjunction with the UE; The software system has the following functions: it can simulate the local ambient temperature, calculate the temperature of the corresponding materials when the ambient temperature changes, maintain data synchronization communication with the UE system through the UE plug-in, analyze and calculate the BIM data obtained from the UE, and realize the synchronous visual interaction of BIM data while demonstrating the UE.

[0029] There are many factors that affect the energy consumption of civil buildings. The main factor is the energy consumed by intervening in the environment, and the most significant of these is the consumption of electricity and heat used to regulate temperature. In order to calculate this energy consumption value, the corresponding algorithm will be added when writing the software system. In essence, the room temperature control range of the building is used as the threshold to calculate the energy consumed by affecting its changes.

Write an algorithm to calculate the energy consumption that affects the building's room temperature to the threshold value and encapsulate it into a software system; Design and develop hardware systems to collect ambient light intensity, ambient temperature, and ambient noise in real scenes; Select common building exterior wall materials, place the hardware system at different locations, and obtain data samples; Analyze the collected data samples, design comparative tests, and study the filtering curves of the impact of environmental data changes on building material data; According to the predetermined plan, use mainstream engineering modeling software (such as UG, SolidWorks, 3d Max) to draw the 3D structure diagram of the building and export it as a UE model file; Import the model file into UE, set UE variables such as light source, ambient sound effects, and ambient buildings, and associate the software system through the plug-in to achieve synchronous visual interaction of BIM data while demonstrating in UE.

[0035] Furthermore, the performing of the light simulation environment analysis on the simulated environment elements according to the simulated environment elements in the parameter synchronization table and the energy consumption analysis table, and performing personalized correction on the simulated environment elements after the light simulation environment analysis, further includes: The temporal environment model determines whether the associated energy consumption interaction strategy of the building model interaction strategy is generated effectively; If the generation of the associated energy consumption to-be-interacted strategy described in the decision fails, determining whether the associated energy consumption to-be-interacted strategy already exists; If the decision-related energy consumption waiting interaction strategy does not exist, it returns the failure of correcting the simulation environment factors; If the decision-related energy consumption interaction strategy exists, the target energy consumption range and the current energy consumption range of the associated energy consumption interaction strategy are collected, and then the communication interaction range between the current energy consumption range and the target energy consumption range is compared to see whether it is within the first completed communication interaction range; When the communication interaction range between the current energy consumption range and the target energy consumption range is within the first completed communication interaction range, it is returned that the correction simulation environment element fails; When the communication interaction range between the current energy consumption range and the target energy consumption range does not conform to the first completed communication interaction range, the associated energy consumption to-be-interacted strategy is then determined, and it is continued to be determined whether the associated energy consumption to-be-interacted strategy of the building model to-be-interacted strategy is generated validly until the decision is generated validly.

[0036] Furthermore, after the time series environment model determines whether the associated energy consumption strategy to be interacted with of the building model strategy to be interacted with is generated effectively, the method further includes: If the generation of the associated energy consumption strategy to be interacted of the decision reference building model strategy to be interacted is valid, the first current building state value is collected, and the first current building state value is set as the first communication interaction parameter, and then it is determined whether the reference building model strategy to be interacted already exists; If the decision reference building model to-be-interacted strategy already exists, the reference building model to-be-interacted strategy is read as target sensor data, and the reference target sensor data is merged with the target sensor data to obtain the target sensor data to be corrected, and then the target sensor data to be corrected is corrected to the prepared to-be-interacted strategy; If the decision reference building model waiting for interaction strategy does not exist, the reference target sensor data is corrected to the ready waiting for interaction strategy; After the modification of the interaction strategy is completed, a second current building state value is collected, and the second current building state value is set as a second communication interaction parameter; comparing whether a communication interaction range between the second communication interaction parameter and the first communication interaction parameter is within the first completed communication interaction range; When the communication interaction range does not conform to the first completed communication interaction range, the correction action is rejected, and the related associated energy consumption waiting interaction strategy and the preparation waiting interaction strategy are deleted; When the communication interaction range is within the first completed communication interaction range, the name of the prepared interaction strategy is modified and amended, and then the related associated energy consumption interaction strategy is deleted.
