测井传输中继的研究与实现

Research and implementation of logging transmission relay

为了实现测井长距离传输,文中提出利用传输中继的方法来解决测井传输中的距离问题。设计了测井中继模型并完成了测井中继的软硬件设计。选用曼彻斯特编码作为中继的编码方式,同时利用硬件描述语言(Verilog HDL)和Quartus II软件在FPGA器件上完成对中继器各功能模块的设计。此外,还通过波形仿真与实物模拟测试,对该传输中继的转发进行了验证,其结果表明,各功能模块均已达到预期效果。

In order to realize the logging long-distance transmission, this article through the analysis of the characteristics of logging transmission transmission relay method is proposed to solve the problem of logging in the transmission distance. The design of encode and decode Manchester code is described by Verilog HDL language and be fitted to the FPGA chips after logic synthesizing and timing simulation based on Qurtus II. Finally, completed the development of the whole system and verify the correct of design.
