摘　　要：提出了一种新型的粮仓温度监测系统,即利用分布式光纤布喇格光栅传感系统从整体上实现对温度的实时监测。在实验基础上,利用origin软件作出了温度与中心波长的关系图,同时与作为标准的K型热电偶测量数据进行对比,偏差曲线显示光纤布喇格光栅测得温度与标准温度接近,偏差在±0.45℃的范围内,表明本监测系统的测量准确度较高,可以满足粮仓温度监测的要求。This paper presents a new type of granary temperature monitoring system, that is the use of dis- tributed fiber Bragg grating sensor system to achieve real-time monitoring of temperature. Basis of experi- ments, use the Origin software to draw a diagram of the temperature and center wavelength, at the same time compares the measuremented data with the K-type thermocouple as a standard. Deviation curve drawn shows fiber Bragg grating temperature close to the standard temperature, deviation within the range of ＋ 0.45 ℃, indicating the high degree of accuracy of the measurement of this monitoring system to meet the requirements of the granary temperature monitoring.
