In order to meet the data acquisition requirements of the common pressure scanner in wind tunnel, a comprehensive data acquisition system of the common pressure scanner in wind tunnel was designed. In this paper, the structure of the data acquisition system of the wind tunnel pressure scanner and the commonly used pressure scanner are summarized. Secondly, the design idea, system composition and implementation method of the system are given in detail. Finally, the system was used to pressure test on two DSA 3217, two PSI 9116, one DSA 3217 and one PSI 9116, respectively. The test results showed that the data differences in the three cases are relatively small, respectively 3.2Pa, 1.6Pa, 9.9Pa, and the maximum time difference of data is also small, respectively 5ms, 8ms, 30ms. Therefore, it can be said that the system has a good synchronization and compatibility, and can realize the comprehensive data acquisition of various pressure scanning valves in the wind tunnel.
