Temperature Measurement System for Cable Connectors Based on Silicon-based Micro-ring Sensors
The traditional cable joint temperature measurement equipment is bulky and not easy to be close to the joint,which makes it difficult to meet the temperature measurement requirements for cable joints.This article designed a cable joint tem-perature measurement system based on silicon-based micro-ring sensors.The main technical method was to apply a disturbance voltage in the form of square root of cosine function to the heating electrode of the micro-ring,the same frequency component of the light frequency and the disturbance voltage was monitored,and the relationship between frequency deviation signal and tempera-ture was obtained.The article conducted theoretical derivation and used Python programs to simulate and verify the theory.Based on this,an experimental verification platform was built,and the relationship between temperature and frequency deviation compo-nent from 0℃to 40℃was fitted,and step-wise rise and drop temperature change experiments were verified.The experimental results show that the temperature measurement accuracy of the system reaches the level of 0.01℃,with high stability.The equip-ment required by the system is simple,the temperature measurement speed is fast,the volume is small,and it has high practical value.
