摘要
文章针对PCM数据传输格式的测井仪器与EILOG05系统配接需求,介绍了一种PCM/DTB井下信号格式转换短节的研制过程,系统采用FPGA作DTB总线时序控制和单片机软编解码的实现方案。通过俄罗斯感应仪与EILOG05的配接试验验证了方案的可行性,具有推广价值。
A logging signal converter between PCM and DTB is introduced in this paper,through which the PCM data transmission format of the well logging instrument can be matched with the EILOG05 logging system.The development of converter is based on the scheme of FPGA for DTB bus timing control and SCM for software coding and decoding.The system has been proved feasible by the experiments of Russian HIL matching with EILOG05 logging system.
