| 摘 要： | 在现代船舶控制系统中,复杂的电磁环境使数字信号的获取与远距离传输面临极大的挑战。本文采用数字式传感器采集数字信号,并将其转换成单位周期包含特定个基准晶振频率周期的频率信号,实现复杂电磁环境下的频率传输。相对传统的数字与频率成线性的D/F（Digital to Frequency Conversion）,F/D转换,数字与周期成线性的转换方式在实时性与精度上具有更大的优势。同时由于采用的是频率传输方式,对于使用环境的适应性更强。且可以根据使用环境的不同,选择最合适的频带,实现抗干扰能力的最大化。

| Abstract: | In modern marine control system,it is a challenge to get and carry out long-distance transmission for digital signal in Complicated Electromagnetic Environment.In this paper,digital sensor is used to acquire digital signal.Then,each digital signal corresponds to a frequency signal which include specific numbered period of reference frequency and make it transmit in complicated electromagnetic environment successfully.This new data transforming method is more real-timing and accuracy than traditional D/F,F/D... |
