摘要:: 荧光氧气传感器在使用过程中，温度变化会降低氧浓度测量精度或测量失效，因此，该文采用氧浓度、温度融合检测技术，通过不同温度下确定氧浓度与温度的经验函数关系，提出一种温度自适应补偿技术，消除温度变化对氧浓度测量精度的影响。通过实验室模拟测试，荧光氧气传感器在（-10～50）℃温度范围内，氧浓度测量精度优于±2.0%FS。

Abstract:: During the use of fluorescent oxygen sensors, sudden changes in temperature will reduce the accuracy of oxygen concentration measurement or measurement failure. Therefore, this paper adopts oxygen concentration and temperature fusion detection technology to determine the empirical function relationship between oxygen concentration and temperature at different temperatures, and proposes a temperature Adaptive compensation technology eliminates the influence of sudden temperature changes on the accuracy of oxygen concentration measurement. Through the laboratory simulation test, the fluorescent oxygen sensor has an oxygen concentration measurement accuracy better than ±2.0% FS in the temperature range of (-10～50) ℃.
