Referring to standard PXI system,using self?developed 4U common chassis as the working platform,adopting the stand?ard RS?422 differential transmission mode for data signals,and combining the multi?serial data transmission and command recognition effectively,the data management idea of one device corresponding to many devices is proposed.Through a combination of software and hardware,the design of the PXI?based multiple serial data management device with higher level of integration is completed.The structure of the hardware design and working principle are mainly introduced,and the workflow of implementing the data management method with DSP and FPGA embedded software is discussed in detail.The function and the performance of the device are verified reliably through the actual use of multiple projects.
