Description

Technical Field

[0001] This invention belongs to the field of building waterproofing and intelligent monitoring technology, specifically relating to an integrated system for building vacuum detection and monitoring of waterproofing. Background Technology

[0002] The integrated building vacuum detection, monitoring and waterproofing system is a high-efficiency technical solution that integrates vacuum detection, real-time monitoring and waterproofing functions. It is mainly used in underground engineering, tunnels, roofs and other scenarios with high requirements for waterproofing and structural stability.

[0003] The current status of this technology both domestically and internationally is as follows: 1. Expanded application scope. Infrared thermal imagers are widely used to inspect the performance of vacuum insulation panels (VIPs) in building envelopes, identifying insulation failures and leaks, significantly improving energy efficiency. Miniature vacuum sensors can monitor the vacuum level of VIPs in real time, ensuring their long-term insulation performance and preventing insulation failures due to decreased vacuum. 2. Intelligent inspection methods. The use of infrared thermal imaging technology allows for rapid identification of defects such as hollow areas and water seepage in building exterior walls through non-contact temperature measurement, improving inspection efficiency. 3. Blockchain data traceability: Some engineering inspection agencies use blockchain technology to ensure the authenticity and reliability of inspection data, preventing falsification of inspection reports.

[0004] The future development trends of building vacuum testing are: 1. Higher precision sensor technology. MEMS (Micro-Electro-Mechanical Systems) vacuum sensors will develop towards higher sensitivity and lower power consumption, such as capacitive miniature vacuum sensors, which can monitor vacuum levels from 10⁻²Pa to 10⁻³Pa in real time, suitable for long-term monitoring of building insulation materials. 2. Deep integration of AI and digital twin technologies. AI algorithms can combine BIM (Building Information Modeling) and IoT (Internet of Things) data to predict the aging trend of building vacuum insulation systems and provide early warnings of maintenance needs. Digital twin technology can simulate vacuum level changes under different environments to optimize building energy-saving design. 3. Automated and unmanned testing. The combination of drones and infrared thermal imagers will become more widespread, enabling automated testing of the airtightness of high-rise building facades and glass curtain walls. Robotic testing systems may enter the building interior to perform non-destructive testing of the vacuum layer inside pipes and walls. 4. Standardization and policy promotion. With the advancement of "dual carbon" goals, building energy-saving testing standards will become more stringent, and vacuum testing technology may be included in mandatory acceptance standards. The government may introduce policies to encourage the development of domestically produced vacuum testing equipment and reduce reliance on imported technology.

[0005] Building vacuum inspection is evolving from traditional manual sampling to intelligent, automated, and high-precision methods. In the future, with the maturation of technologies such as AI, IoT, and MEMS sensors, vacuum inspection will become more accurate and efficient, playing a greater role in areas such as building energy conservation, structural safety, and material performance evaluation. At the same time, the industry still needs to address issues such as data falsification and the localization of equipment to drive a comprehensive upgrade of building inspection technology.
