摘要
针对测井中地面系统与井下仪器通信的可靠性差,设计了用于井下仪器与地面系统进行通信的MIL-STD-1553B总线通信接口电路,实现了曼彻斯特编码、解码技术;在Libero开发环境中,用Modelsim进行时序仿真,并用综合工具Synplify对设计进行综合、优化,最后在FPGA上实现编解码技术,提高了测井系统通信的实时性、可靠性。
The 1553B bus communication interface system is designed based on FPGA ＋DSP. The design of encode and decode Manchester code is described by VHDL language and be fitted to the FPGA chips after logic synthesizing and timing simulation based on libero IDE. Finally , completed the development of the whole system and verify the correct of design.
