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。
Aiming at the problem that DFTI digital interface output and data acquisition system format are not matched, the difference between DFTI digital interface output signal format and standard RS-422 signal is analyzed emphatically. A design scheme of signal conversion is proposed. Through the design of signal conversion The device finally achieves DFTI digital interface signal acquisition.
