摘　　要：为了对建筑材料不燃性试验炉进行量值溯源,确保试验结果的准确性和可靠性,通过对试验炉温度分布模型研究,设计研制了一套建筑材料不燃性试验炉动态校准装置。装置采用热电偶高温检测和温度补偿技术对试验炉的温度进行动态检测,利用伺服电机和滑动平台实现传感器在高温炉内自动定位,利用LabVIEW处理校准数据并通过触摸显示屏输出校准结果。研制的校准装置经检测,性能达到设计要求,试验炉各参数校准的验证结果均在标准规定的范围内,校准不确定度满足量值传递要求。To ensure the accuracy and reliability of the test results, a set of dynamic calibration device for noncombustibility test furnace of building materials was designed and developed through the study of the temperature distribution model of the test furnace. The device adopted thermocouple high-temperature detection and temperature compensation technology to realize the dynamic temperature detection of the test furnace, and the servo motor and sliding platform were designed to realize the sensor automatic positioning in the high-temperature furnace. The LabVIEW data processing technology and touch screen design were equipped to achieve calibration data processing and calibration results output. The developed calibration device was tested and its performance met the design requirements. The verification results of the calibration of each parameter of the test furnace were within the range specified by the standard, and the calibration uncertainty met the requirements for value transmission.on.
