Abstract:
In order to improve the integration and reliability of the system, reduce the power consumption and the cost, enhance the flexibility of the system, this paper describes the matching problem of input cable and output cable of various digital baseband transmission codes commonly used in the field of production logging, and describes the development of a new type of ground numerical control logging based on PXI bus. In the project, a large-scale field programmable gate array(FPGA)is used to realize the hardware design of encoding and decoding of digital baseband coded signals for common digital baseband logging signal processing techniques. The FPGA and CPU are interconnected, the hardware design is redundant, and the data acquisition mode of the logging signal is flexibly controlled. The internal logic can be controlled by the ground host computer according to the actual logging needs. The design of the encoding and decoding is flexible, and the design of the FPGA can be optimized at any time. The bidirectional digital baseband coded logging signal is completed. Data transmission ground hardware many logging functions.
