Research And Design Of Well-Logging Data Acquisition Board Based On CPCI Bus

This thesis proposed a design and implementation of a well-logging data acquisition intelligent IO board based on CPCI Bus, on the base of deeply understanding the mechanism of CPCI bus and data acquisition technology, which includes data acquisition, data processing and self-diagnosis, etc.The effective filter circuit has been designed in the board for the specific application environment to effectively filter sensitive noise signals. And more importantly, high performance A/D,FPGA and DSP chips are adopted for data acquisition, and data transmission is accomplished by high bandwidth CPCI Bus. According to practical engineering experience, it is a feasible hardware design for well-logging data acquisition.This paper carried out the research work of hardware circuit design for data acquisition, PCB design and debugging of the circuit board. It also has important reference meaning to design data acquisition card for other non-logging equipment.
