地球物理测井井下信号的数字化处理装置

A Underground Signal Digitalizer for Geophysical Well-logging

为了实现地球物理测井的数字化 ,采用GMS97C2 0 5 1单片机和TLC2 5 4 312位串行A/D转换器设计了一种地球物理测井井下信号采集 /传输模块。该模块可在探管内将探测信号数字化 ,数字化的测井信号由电缆传送至地表仪器 ,从而降低了信号的失真度。

In order to realize the digitalisation of geophysics well-logging, the authors have made used of model GMS97C2051 single-chip microcomputer and TLC2543 A/D serial converter with 12 bits to develop a kind of underground signal collection/ transmission module for geophysical well-logging. This module can digitize the signal inside exploring pipe and transfer the digitized signal to the instrument on surface by cable, thus can reduce the distortion of the signal. This paper presents the block diagram of the hardware and principal source program.
