NI LabVIEW software helps the building health monitoring of the 2008 Beijing Olympic Games venues

July 2008 - National Instruments (Ni) recently announced that the China Earthquake Administration (CEA), the government agency responsible for national earthquake preparedness and disaster reduction, has selected the building health monitoring (SHM) solution developed by CGM Engineering Company (a partner of national instruments). The solution is based on the Ni L abview graphical system design platform that can realize the centering effect and the system developed by Ni compactrio programmable automation controller, which is designed to help engineers monitor the building health of six newly built super large buildings. The six landmark buildings include the two main venues of the 2008 Beijing Summer Olympic Games - Beijing National Stadium and China National Water Sports Center

the energy-saving design of indemnificatory housing buildings submitted for the review and filing of construction drawing design must meet the requirements of the Guidance Opinions

"the main goal of the project is to develop a cutting-edge building health monitoring solution. The stability, reliability, habitability and other structural health characteristics of the building are monitored in real time by using the latest computing technology, sensors and communication technology." Mr. Chris McDonald, vice president of CGM engineering company, said: "the system we designed can collect the vibration of the building structure, which will seriously affect the measurement results of the equipment, detect any sudden changes in structural characteristics, improve the building structure, and help reduce the loss of life and property in the event of major disasters such as earthquakes, hurricanes, fires and so on."

9 64 channel and 2 36 channel SHM systems designed by CGM company each contain multiple compactrio controllers. It can be directly connected to an accelerometer with vibration measurement and a time-based GPS receiver synchronized in the real-time chassis. In the chassis, the LabVIEW FPGA module can ensure that the error between the data of each test channel and the data obtained on the GPS receiver is kept within ± 10 microseconds. LabVIEW real-time module is also used to program user configurable filters to avoid the interference of unnecessary noise on low-frequency measurement. Each system is hermetically installed in a solid NEMA standard box, which makes it convenient for the equipment to operate in an environment with high humidity and large temperature difference (-40 ° C to 70 ° C)

shm system can monitor each area continuously and in real time, and engineers can remotely receive locally stored data through a secure Internet connection anywhere in the world. Moreover, in case of any unexpected situation, engineers can use independent or multi architecture to configure the system and send email notifications

the China Seismological Bureau chose the system based on Ni technology in many schemes, precisely because Ni has the advantages of continuous and real-time monitoring, time-based GPS synchronization and realizing the highest number of channels at the lowest cost. Ni technology can also support simple out of the box installation modes that are mostly abandoned and a variety of i/o options, so that reconfiguration can be completed quickly and easily when system requirements are updated

in addition to the Beijing Olympic Games venues, the SHM system has also been applied to the 104 story Shanghai World Trade Center building, the 66 story Beijing Park Hyatt Hotel, the 240 meter Ertan concrete arch dam, the 8266 meter long Shantou cable-stayed bridge, and the Beijing China Earthquake Administration data center with seismic isolation structure. Finally, the data obtained from this study will be used to improve the building integrity of future buildings and reduce the casualty rate in disaster accidents
