摘　　要：目前石油工业的发展迈入了智能化、自动化的时代,而这一切都要求对井下信息有更准确、快速的掌握,所以需要一种新的抗噪性能更好、信息传送速率更高的信息编码方式,来满足对井下情况的掌握。本文利用FPGA电路设计了一套适用于新形势下石油测井信息传输链路的设计方案,并使用VerilogHDL模块设计了差分曼彻斯特的编、译码器,在ALTERA公司的QuartusⅡ9.1软件平台上完成了硬件及软件仿真。At present, the development of oil industry has entered in the era of intelligence and automation, and all these require a more accurate and fast grasp of underground information, so a new information coding method with better anti-noise performance and higher information transmission rate is needed to satisfy the mastery of underground conditions. In this paper, based on FPGA circuit, a set of design schemes suitable for oil logging information transmission link under the new situation was designed. And differential Manchester encoder and decoder were designed by Verilog HDL module, hardware and software simulation was completed in ALTERA corporation Quartus Ⅱ 9.1 software platform.
