摘　　要：针对电传系统DFTI数字接口输出与数据采集系统格式不匹配的问题,重点分析了DFTI数字接口输出的信号格式与标准RS-422信号的差异,提出了信号转换的设计方案,通过设计制作信号转换器最终实现对DFTI数字接口信号的采集。To overcome the problem of not matching between DFTI digital interface output signal formats and the data acquisition system input formats, the difference of DFFI digital interface output signal formats with standard RS-422 signal are analyzed emphatically, the design scheme of signal conversion is presented, DFFI digital interface signal acquisition is realized by the signal convertor.
