摘要
文章分析了EXCELL-2000成像测井仪的井下调制解调器的工作原理以及其功能的实现。从曼彻斯特码的帧结构出发,在阐明曼彻斯特码基本工作原理的基础上,应用FPGA技术,利用硬件描述语言Verilog HDL设计完成曼彻斯特码编解码功能,所编写的Verilog程序经Active HDL进行调试、优化以及仿真,其仿真结果与理论分析完全吻合。
This paper analyzes the working principle and the realization of the functions of the downhole modem of the EXCELL-2000 imaging logging tool. It also discusses the frame structure and principle of the Manchester, applies the EDA technology and designs a Manchester code and decode functions by hardware description language Verilog HDL. Through debugging, optimizing and simulation the source program by the software Active-HDL, the result accords with the theoretical result.
