摘　　要：在大跨度空间结构非均匀温度场的监测数据处理中常常需要处理温度数据,但是传统的温度识别处理方法在处理非均匀温度场数据时过于粗糙,无法较好地保留温度场的数据细节。因此通过BOLL通道(Bollinger bands)法巧妙引入第三方数据与原始数据构建上下轨线,求取偏离值得到改进型BOLL通道法完成对非均匀温度场异常温度识别处理。同时与对比了移动平均线法和三西格玛准则在数据识别处理的优劣。研究结果表明:改进型BOLL通道法在识别处理非均匀温度场数据方面的最大优势在于具有独特的区域自适应性,在识别异常温度值的同时较好地保留非均匀温度场的突变温度细节,并且可以同时处理漂移温度数据和跳点温度数据。实际处理异常温度的精度优于移动平均线法和三西格玛准则,应用于非均匀温度场数据处理方面具有较大优势。In monitoring data processing of non-uniform temperature field of large-span spatial structures,it is often necessary to process temperature data.However,the traditional temperature identification processing method is very rough processing the non-uniform temperature field data,and it can't better retain the details of the temperature field data.Therefore,the BOLL channel(Bollinger bands)method to introduce the third-party data and the original data was used to construct the upper and lower trajectories,calculate the deviation value,and get the improved BOLL channel method to complete the identification and processing of the relevant non-uniform temperature field abnormal temperature.At the same time,the advantages and disadvantages of moving average method and three sigma criterions in data recognition and processing were compared with BOLL channel method.The results show that the improved BOLL channel method has unique regional adaptability in identifying and processing non-uniform temperature fields,and retains the sudden change temperature details of non-uniform temperature fields while identifying abnormal temperature values,and it can process drift temperature data and jump point temperature data at the same time,and it processing abnormal temperature is better than that the moving average method and three sigma criterion,which has great advantages in corresponding temperature field data processing.
