制冷系统中的温度数据融合测试

摘要

为提高测量的准确度、保证测量结果的可靠性,采用估值理论将处于不同空间位置的温度传感器观测值融合在一起,以最小方差的准则确定评估融合参数,实现了温度数据的融合测试.这种数据融合的测试方法既可以消除温度测量中的干扰,同时也提高了测量的准确度.在制冷机械温度测量中应用此方法,测量效果得到明显改善.%In order to enhance the measurement accuracy and ensure the reliability of the measured result, by adopting evaluation theory, the observed values from temperature sensors located in different location are fusibly handled. The fusion parameters are evaluated with the minimum variance criterion to realize fusion test for temperature data. This kind of test method for data fusion can eliminate the interference in temperature measurement, and also enhance precise of measurement. The method has been applied in temperature measurement of the refrigeration machinery with obviously enhanced measurement effects.
