Description

Technical Field

[0001] This invention relates to the field of intelligent building construction, specifically to a BIM-based integrated intelligent building construction management system for low-energy prefabricated modular housing. Background Technology

[0002] Against the backdrop of rapid development of information technology, increasing maturity of IoT and AI technologies, and continuous improvement in consumers' demands for quality of life, safety, and convenience, a BIM-based integrated intelligent building construction management system for low-energy prefabricated modular housing has emerged. It aims to enhance the living experience by integrating innovative technologies to achieve intelligent interconnection and efficient management of home devices.

[0003] In most existing buildings, construction companies can only build a new model home first, then leave the interior design and decoration to the client, making it difficult to guarantee the client's personalized requirements. Traditional housing construction involves collaboration among developers, builders, designers, contractors, supervisors, and relevant government departments, making it difficult to provide a one-stop customized service. Construction companies cannot accurately control the client's desired floor plan, instead building according to the construction drawings. This results in minimal regional differences in housing types, hindering the creation of innovative and unique architectural styles. Furthermore, with the advancement of technology, many traditional decoration and renovation companies are starting to take on business through online platforms. They often win contracts by offering the lowest bids during the bidding process. However, to increase profit margins, these companies may resort to unethical practices, such as reducing the quality of construction materials, simplifying construction processes, or even arbitrarily increasing the scope of work, ultimately harming the client's interests.

[0004] In the face of the various problems in contemporary society, intelligent building construction management systems urgently need a scientific, rational, transparent, and comprehensive construction system that integrates network, information, and physical services. This system would provide customized, integrated services for prospective homebuyers, and offer a transparent, secure communication platform for both construction companies and clients to make informed choices. It would provide integrated management for both clients and construction companies, ensuring complete construction information, customized services, and full traceability throughout the entire construction process. This would significantly reduce time and management costs for both parties, providing clients with high-quality, low-cost, and more comfortable customized services, and offering construction companies more accurate and complete construction solutions. Summary of the Invention

[0005] This invention provides a BIM-based integrated intelligent building construction management system for low-energy prefabricated residential buildings. This system addresses the technical problems of existing technologies, which lack a construction system for communication between customers and construction parties during the design process and cannot effectively verify and monitor the actual operation of the designed intelligent building in real time. This results in discrepancies between the design content of the intelligent building and the actual needs of customers, leading to increased failure rates and higher energy consumption in actual use of the intelligent building.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a BIM-based integrated intelligent building construction management system for low-energy prefabricated modular housing, characterized by comprising a client and a construction end.

The construction end includes an information data acquisition unit, a structural design unit, a BIM building model processing unit, a data analysis unit, a virtual simulation unit, an automatic control unit, and a human-computer interaction unit. The results are analyzed, and any non-compliant content is sent to the structural design unit.

The simulation unit performs a secondary simulation of the optimized prefabricated building structure. The drawing generation unit converts the prefabricated building design content into drawing information.

[0007] The principle and advantages of this solution are as follows: It enables personalized services and efficient building management for users through a client-side and construction-side approach.

[0026] The following detailed description, with reference to the accompanying drawings, outlines several specific embodiments of the present invention, and provides further elaboration:

[0027] Service location units improve space utilization efficiency through intelligent positioning and resource scheduling, which directly impacts the operating expenses of associated cost units. More efficient space utilization significantly reduces resource waste caused by idle space, thereby substantially lowering operating costs. Furthermore, the application and maintenance of service location unit technology inevitably incur costs, requiring careful accounting and management within associated cost units to ensure overall costs remain within a controllable range.

[0028] The optimization of service location units is closely linked to other units. Precise positioning and intelligent resource allocation achieved through the integration of multiple technologies improve space utilization efficiency, which directly helps reduce operating costs. For example, in a commercial building, precise service location ensures a more rational layout of shops, reduces vacant areas, and thus lowers rental costs in related cost units. Simultaneously, efficient resource scheduling can reduce unnecessary equipment investment and operating expenses.

[0029] The energy-saving effect of the energy monitoring unit also has a significant impact on the associated cost units. When the energy monitoring unit achieves precise monitoring and optimized allocation of energy through advanced technology, it can significantly reduce energy costs. This energy-saving effect is directly reflected in the cost accounting of the associated cost units, making overall costs more controllable. In addition, the service location unit works in conjunction with the energy monitoring unit, for example, to intelligently control lighting and air conditioning systems based on personnel distribution, improving user experience while achieving efficient energy utilization.

[0030] The after-sales service unit plays a crucial role in ensuring the effective operation of the other three units. Its 24 / 7 hotline and remote support can promptly resolve any technical malfunctions that may occur in the positioning unit, ensuring the continuous and stable operation of the positioning service. For the energy monitoring unit, after-sales service guarantees the normal operation and data accuracy of sensors and other equipment, providing reliable support for energy management. In the related cost unit, after-sales service can help answer user questions about cost composition and cost control, improving user acceptance and satisfaction with cost management.

[0031] The associated cost unit provides crucial financial and cost planning support for the development of other units. It guarantees the budget for the service positioning unit's technological upgrades and equipment maintenance, enabling continuous optimization and innovation in service positioning. Simultaneously, the associated cost unit also provides financial support for equipment updates and technological improvements in the energy monitoring unit, driving continuous improvement in energy management. For the after-sales service unit, the associated cost unit rationally plans service costs to ensure high-quality, efficient after-sales service that meets user needs.

[0032] The service positioning unit primarily achieves refined management of building interior spaces through the following methods: It integrates various advanced positioning technologies, such as Wi-Fi, Bluetooth Low Energy (BLE), Ultra-Wideband (UWB), and Inertial Navigation Systems (INS). This fusion of technologies provides high-precision, comprehensive positioning information, accurately sensing the location of people and objects within the building. By monitoring and analyzing user behavior patterns in real time, the service positioning unit can understand users' dwell time, activity frequency, and movement paths in different areas. For example, it can identify areas where large numbers of people frequently linger for extended periods, while other areas are rarely visited. Based on this deep understanding of user behavior, the system can intelligently allocate and schedule resources. For instance, it can increase service facilities, lighting brightness, or ventilation intensity in densely populated areas; and appropriately reduce resource investment in low-frequency areas to achieve optimal resource allocation. Personalized service delivery is also a crucial means of achieving refined management. The service positioning unit can push relevant information and services to users based on their location and preferences. For example, when a user approaches a store, promotional information about that store can be pushed to them. Environmental awareness and adaptive adjustment strategies enable the service positioning unit to dynamically optimize service paths and service content based on changes in the building's environment, such as temperature, humidity, and lighting. For example, it can automatically increase lighting in dimly lit areas or increase ventilation when the temperature is too high.

[0033] The information and data acquisition unit, as the foundation of the entire system, plays a crucial role. Its high-precision, multi-modal data collection capabilities comprehensively cover all aspects of the built environment and user needs. This allows the structural design unit to obtain extremely detailed and accurate information, including but not limited to climate conditions, geological conditions, and pedestrian flow distribution. With this comprehensive information, the structural design unit can conduct more scientific and optimized structural layouts and carefully select suitable building materials, thereby ensuring building stability while maximizing user needs and improving space utilization efficiency.

[0034] The meticulously optimized results of the structural design unit provide the BIM model processing unit with incredibly precise design parameters. These parameters act like precise blueprints, enabling the BIM model processing unit to perform meticulous error detection and assembly management. By strictly controlling the precision of every step, the accuracy and efficiency of the construction process are ensured, unnecessary errors and rework are avoided, the construction cycle is significantly shortened, and costs are reduced.

[0035] The data analysis unit acts like an intelligent brain, deeply processing and precisely analyzing massive amounts of data from multiple sources, including the information data acquisition unit and the BIM model processing unit. The resulting analysis provides powerful data support for the virtual simulation unit, making the simulation more closely resemble real-world building scenarios. This not only helps provide valuable references for optimizing structural design and construction strategies but also enables the early detection of potential problems and the proactive development of solutions.

[0036] The simulation results from the virtual simulation unit can be fed back to the information data acquisition unit, further clarifying and refining the scope and focus of data acquisition. Simultaneously, it opens up more design possibilities for the structural design unit, helping to optimize design schemes through continuous verification and comparison, making them more complete and excellent.

[0037] The human-computer interaction unit (HCI) is closely related to and indispensable to other units. It allows users to easily access raw data collected by the data acquisition unit, deeply understand complex analytical results from the data analysis unit, and smoothly participate in virtual simulations and other processes through a concise and clear interface, all in a user-friendly and intuitive way. Simultaneously, user feedback and personalized needs during use can be promptly transmitted to other units through the HCI, forming a virtuous cycle that continuously drives the optimization and upgrading of the entire system.

[0038] During the specific stages of architectural design, the information and data acquisition unit collects site environmental data, such as topography, wind direction, and wind speed, and accurately transmits it to the structural design unit. Based on this, the structural design unit develops a preliminary design scheme, which is then refined and rigorously error-checked in the BIM model processing unit. The data analysis unit conducts in-depth analysis of the relevant data, providing a solid foundation for the virtual simulation unit. The simulation results are clearly presented to designers and users through the human-computer interaction unit, and their valuable feedback is then relayed to other units through the human-computer interaction unit, prompting continuous adjustment and optimization of the design scheme to ultimately achieve the desired effect.

[0039] In this scheme, when constructing the prefabricated residential integrated intelligent building, the designed intelligent building is generated into a prefabricated residential integrated intelligent building model. The model is then subjected to preliminary testing and simulation testing in sequence. This process of preliminary testing and simulation testing allows for the screening of problems in the design content of the prefabricated building, thereby improving the completeness of the prefabricated residential integrated intelligent building construction and its matching degree with the actual environment.

[0040] The above description is merely an embodiment of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not elaborated upon here. It should be understood that those skilled in the art can make various modifications and improvements without departing from the technical solution of the present invention. These modifications and improvements should also be considered within the scope of protection of the present invention and will not affect the implementation effect or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments and other related descriptions in the specification can be used to interpret the content of the claims.
