Design and Implementation of Wind Load Resistance Performance Data Acquisition System of Building Curtain Wall

다국어 초록 (Multilingual Abstract)

With the development of the curtain wall industry and expiration of the curtain wall structures which designed and built in the early life, the testing for building curtain walls will be increasingly focused on. In this paper, a Client/Server structure acquisition system of the curtain wall wind pressure resistance characteristics data, which is based on the Advantech data acquisition card PCI-1747U, has been designed and implemented for the GB/T 15227-2007 (Test method of air permeability, watertightness, wind load resistance performance for curtain walls). The hardware of the data acquisition system contain three major components: The sensor part; The signal conditioning circuits part, which consists of sensor supply circuit, I-V conversion circuit and filter circuit; data acquisition part consists of Advantech card PCI-1747U and Advantech industrial computer 610L. The software of the system contain the data acquisition Server and data processing client. They communicate through TCP/IP protocol and complete the sensor calibration, static test and dynamic test of the wind load performance data, query and output historical data and other functions. Microsoft SQL Server 2000 database was used to management the test data. After running and debugging, the system’s sample time and accuracy reached the requirement of wind load resistance performance test.
