| Abstract: | As the problem about the weak signal processing, high-speed and real-time collection, reliable storage in the field system, design a data acquisition circuit based on PCI bus. Circuit system through high speed AD chip let the analog input signals effective sampfing, and in the control of FPGA the process data uploaded to PC for analysis and preservation, in order to make weak data signals achieve high-speed acquisition, stability, reliable transmission and display. |
