Design of Dynamic Electronic Pressure Collection System and Gust Measurement

Abstract

Through the communications of Seater Model 265and Model 267MR-type differential pressure sensors with industrial automation software, a set of electronic pressure acquisition device is established. The dynamic measurement system is composed by the device and PIV to carry on the experiment of wind pressure measurements on buildings in environment wind tunnel under the gust flow. The dynamic system can achieve rapid synchronous pressure measurement on multipoint and automatic recording. Through the dynamic wind pressure measurement on buildings with the flow of sinusoidal wind spectrum, the system is proved to be feasible and reasonable. The system can make a correct response on low-frequency gust and provide the basis and effective means for further study on the dynamic measurement under the gusts.
