【摘要】 目的建立定量采样机器人采样法检测集中空调风管内表面积尘量的不确定度分析方法,找出其影响不确定度的因素,对不确定度进行评估,给出不确定度。方法根据《公共场所集中空调通风系统卫生规范》附录H,建立不确定度的数学模型,系统分析计算不确定度各分量。结果用人人康RRK-SR-I型定量采样机器人采集风管内表面积尘量,当平均积尘量为18.42g/m2时,其扩展不确定度为4.716g/m2(K=2)。其中采集率对测量不确定度影响最大。结论此方法适用于评估定量采样机器人采集风管内表面积尘量的测量不确定度。更多还原

【Abstract】 Objective To establish a system that can analyze the measuring uncertainty of a dust-gathering robot used in the air duct of a central air conditioner system,find out the influencing factors of the measuring uncertainty,and evaluate and calculate the uncertainty. Methods According to addendum H of "Hygienic Standard for Central Air Conditioner System in Public Places",a mathematic model for measuring uncertainty,calculating the component factors was established. Results The dust on the surface of an air duct by using the dust-gathering robot of type RRK-SR-I was gathered. When the average weight of the dust was 18.42g/m2,the extending uncertainty reached up to 4.716g/m2(K=2),and the gathering rate had the most significant influence on the uncertainty. Conclusion This method can be used to evaluate the measuring uncertainty of the dust-gathering robot when measuring the weight of the dust on the surface of an air duct.更多还原
