| Abstract: | An introduction to the design and development of the data acquiring and processing system used for the XNJD-1 Wind-Tunnel is made in this paper.The system has the ability to make pressure and force measurements simultaneously;Also,it is able to carry out other operations such as pressure online calibration,analogue channel standard signal calibration etc.In the design of the system,many new concents are involved,for example,eletronic scanning pressure measurement,conditioning of analogue signals and so on. Experiments show that the system possesses the following advantages:quick aquirement,high stablity,complete soft-and hardware functions, rapid data processing and convenient for maintaining etc. |
