Study on reflective optical fiber current sensor signal processing simulation

反射式电流传感器比一般的光纤电流传感器的灵敏度提高了4倍,并且集中了光纤电流传感器的优点,逐渐成为人们普遍关注的新型的电流传感器。但是光纤电流传感器的输出信号较小,一般都会被噪声淹没,因此对其的信号的后期处理是反射式光纤电流传感器必须解决的问题。介绍了反射式电流传感器系统组成,针对其输出信号特点进行处理,并在MATLAB中进行了信号处理仿真,取得了很好的效果。

The sensitivity of reflecting current sensor improve four times than the sensitivity of the optical fiber current sensor,and focused on the advantages of fiber-optic current sensors,new current sensor is becoming widespread concern.output signal of fiber-optic current sensor is smaller,usually drowned by the noise,So post processing of the signal is to solve the problems of reflective optical fiber current sensor.Composition of reflex current sensor system was introduced,according to the characteristics of the output signal and processing,and the signal processing simulated in Matlab,and good results have been achieved.
