摘　　要：研究了脉冲中子多参数能谱测井仪（即阿特拉斯３７００－２７２７Ｃ／Ｏ（碳氧比）测井仪）的数据传输和地面计算机控制数据获取过程，设计了以８０Ｃ１９６单片机为微处理器的智能碳氧比地面数据获取系统。该系统采用软件的方法完成对曼彻斯特码的编码和译码，并具备较强的通讯诊断和井下仪器的诊断功能，在Ｃ／Ｏ测井方面的功能与２７２７完全一致。The communication between the ground computer and the pulsed neutron multi-parameter spectrum instrument in well logging, i.e. Atlas-Dress 3700-2727 C/O well logging instrument, is studied. A data acquisition system based on the microprocessor 80C196 is designed. The 80C196 can encode as well as decode the Manchester code by means of software. Furthermore, the system has a diagnostic function for checking the transmission performance.
