摘　　要：为了解决供热企业量化管理中大量基础数据的分析问题,在采集的供热数据基础上,针对锅炉出水温度提出一种供热过程评价方法.该方法通过分析出水温度曲线与目标温度曲线的关系,提出从曲线趋势变化、平移、伸缩3个属性衡量两条曲线的一致程度,分别计算各个属性的相似度,然后加权融合为一致性度量,用以评价供热过程.实验结果证明了该评价方法的有效性,可为锅炉管理人员量化供热管理指标提供参考依据,促进节能减排.To analyse the basic data in the quantitative management of heat-supply enterprises,a heating process evaluationmethod to get the temperature of boiler’s output water was proposed based on collected heating data.By analyzing the relationshipbetween the temperature curve of the output water and the target temperature curve,the consistency of the threecharacters of the two curves namely the changes,translation and elasticity of the curve trend can be measured.The similarityof each character is calculated separately first,and then a weighted value is added to integrate them into a consistent measurementto evaluate the heating process of the boiler.The experimental result has illustrated the effectiveness of such anevaluation method.This method provides some reference for the quantitative management index of the heating process ofthe boiler operator as well as relevant facilitates.It can lead to energy saving and emission reduction.
