Research on Internal Temperature Measuring Antenna in Cable Joints Based on SAW
摘要
由于声表面波(SAW)测温技术因具有无源无线的特点而备受研究人员的广泛关注。该技术可应用在电缆接头内部的温度测量中, 但因受电缆接头材料和结构的影响, 使SAW测温信号传递受阻, 严重影响了温度信号的检测。该文基于DWG-630A型电缆接头的结构和材料, 设计了一款可用于电缆接头内部测温的天线。通过其理论分析、仿真及试验验证, 证明该设计切实可行。结果表明, 穿过电缆接头可传递SAW温度信号, 并在工作频段内具有良好的增益和辐射效果。
Abstract
In recent years, surface acoustic wave (SAW) temperature measurement technology has received wide attention because of its passive and wireless characteristics. This technology can be applied to the temperature measurement in the cable joints. However, the SAW temperature measurement signal transmission is hindered by the influence of the material and structure of the cable joints, which seriously affects the temperature signal detection. Based on the structure and material of DWG-630A cable joints, this paper designs an antenna that can be used for temperature measurement in cable joints. Through the theoretical analysis, simulation and experimental verification, it is verifies the design is practical. The results show that it is feasible to transmit SAW temperature signal through the cable joints and has good gain and radiation effect in the operating frequency band.
