采用DSP技术的测井高速数据传输系统

Well Logging High Speed Data Transmission System Based on DSP Technique

介绍了一种基于数字信号处理技术和信道均衡原理设计的高速测井数据传输系统 .系统均衡采用间歇训练的自适应工作方式 ,运算量大幅度降低 .用一片DSP芯片ADSP 2 1 0 2 0完成对信号的实时均衡处理 .原型系统在 3 0 0 0m测井电缆上进行的实验达到 50 0kbit/s的传输率 .

Well logging high speed data transmission system is proposed, which improves the data transmission rate greatly by DSP technique. Since the equalizer of this system works in an intermittent training mode, the equalizing operation quantity is greatly reduced, so the equalization function can be achieved by only one DSP chip ADSP 21020. The data transmission rate of this system can reach 500?kbit/s in 3?000?m cables.
