Building glass curtain wall is expected to alarm real-time

Fanyu 2017-11-10 10:39:02
A building glittering and translucent glass curtain wall construction, the city's beautiful scenery, but the building curtain wall also has the security hidden danger, in recent years, the glass explodes, falls and so on the accident has heard. How to achieve effective security risk identification and control? Supported by the Municipal Science and Technology Commission, Shanghai Jiaotong University, Chinese Academy of Sciences Shanghai Micro System and IT research Institute and Shanghai Building Materials Group Energy-saving Environmental protection Technology Co., Ltd. jointly launched the building curtain wall Intelligent Monitoring System project. Recently, the monitoring of toughened glass sensors in the building materials group laboratory was born. It is expected that the system will be put into use in the near future.
The city was first builtGlassCurtain wall Construction has been more than 30 years, and the early construction curtain wall used structural sealant only 10 years, if the monitoring is not enough, many curtain wall has the risk of shedding. 20% of the city's glass curtain wall construction 1997 years ago, early in the city to introduce glass curtain wall-related standards of time, its design, acceptance is not standardized, more prone to security risks. The safety hidden trouble of glass curtain wall is divided into four categories: the tempered glass self explosion, the structural sealant Aging, the connection piece year long lapse, the nonstandard design and the construction causes the latent risk. At present, the monitoring of these hidden dangers is mainly based on staff experience and handheld devices, efficiency and accuracy is relatively low, can not be reported in real-time the status of each curtain wall.
At the moment, the "IoT + Big Data + Artificial Intelligence" program has been able to solve this problem. In the field of IoT, Shanghai Building materials group developed a "Si" sensor, affixed to the glass curtain wall, can monitor the temperature, vibration frequency, stress and strain, displacement and other 4 kinds of data, real-time recording curtain wall state, and transfer it to a large data management platform. The Chinese Academy of Sciences Shanghai Micro System is responsible for data transmission link, 4 kinds of data wireless transmission time in 1 seconds. Shanghai Jiaotong University is responsible for large data and artificial intelligence analysis, through the construction of mechanical models, computer simulations and experiments, to investigate which curtain wall need to stick sensors. "We are working on a cost-effective sensor placement program to achieve lightweight data," said the head of the Shanghai Jiaotong University Project group. "Lightweight" data, large data management platform can carry out artificial intelligence analysis, in addition to the security of the curtain wall, it can also analyze the curtain wall insulation, noise and other situations, become an important part of the building information model.
It is understood that the modern building curtain wall, including glass curtain wall, is gradually integrated into solar photovoltaic power generation, wind power, geothermal energy and other green sources, and towards the direction of intelligent development. Shanghai Building Materials Group Energy-saving Environmental protection technology company is cooperating with Shanghai Jiaotong University to promote the upgrading of China's building curtain wall.
