| 摘 要： | 乳化液作为液压支架的传动介质,其浓度大小直接影响液压支架和支柱的工作寿命及成本,因此对乳化液浓度严格检测十分必要。基于光纤的宏弯损耗原理,提出一种光纤乳化液浓度检测仪的设计方案,分析了影响损耗的因素,另外对乳化液的折射率特性进行了测试实验,分析了乳化液浓度与其折射率之间的关系,介绍了检测仪的系统组成和软、硬件设计。这种光强调制型光纤传感器结构简单,具有灵敏度高、抗电磁干扰和耐腐蚀的特点,能够实现对乳化液浓度的在线检测。

| Abstract: | Emulsion is a hydraulic support’s transmission medium and its concentration directly affects the working life and cost of the hydraulic support and the pillar,so strict testing for emulsion concentration is necessary.Puts forward a design scheme of the optical fiber emulsion concentration detector on the basis of the macrobending loss principle of the optical fiber,analyze the influential factor on the loss and experiment with the characteristics of the refractive index of the emulsion and analysis of the relationship between emulsion concentration and refractive index,then introduces the system configuration and the design of the software and hardware of the detector.This light intensity-modulated optical sensor has the characteristics of the simple structure,high sensitivity,anti-electromagnetism interference and corrosion resisting,which can realize the online inspection of the concentration of the emulsion. |
