基于忆阻桥效应的光纤式双光路结冰探测方法
|
摘要
近年来,随着防冰、除冰需求的增加,结冰探测技术受到了广泛关注,但传统的结冰传感器量程受限,且后续信号处理电路部分体积较大,难以满足应用需求。基于双光路差动测量的方法,提出一种正方形光纤束探测头分布模式和具有放大效应的忆阻桥网络结构,该网络结构通过对光电探测器的输出光电流信号进行放大,并以网络中感知忆阻器的端电压作为传感输出,从而实现冰层厚度的测量。试验仿真结果表明,该方法探测头端面的安装面积较常用圆形端面光纤束可减小约12.6%,且能够有效消除光路扰动和扩大结冰厚度的测量范围,结冰厚度的测量范围可达到38 mm。
In recent years,a great effort has been devoted to the study of icing detection technology with the requirement of de-icing. However,the measurement range is limited by the front slope and back slope of detective curve,and the circuit size is large. In order to solve the above problems,this paper presents a square end surface probe distribution mode as well as a memristor-bridge structure which has signification amplification. The memristor-bridge detects the ice thickness by sensing voltage across the perception memristor. Experiment and Simulation results show that the installation area is 12.6% less than the traditional optical fiber probe,and the bridge structure is capable to eliminate optical path disturbance and enlarge ice thickness measurement range to 38 mm.
