Abstract: The invention discloses a control and diagnostic method for a water chilling unit. The fusion method comprises the steps of collecting measurement data after direct and indirect measurement of air conditioning load; when direct measurement data are singular values, removing the direct measurement data, and using indirect measurement data to carry out data fusion; or else, after removing measurement noise in collected data through a moving average method, performing data fusion to the data which the measurement noise is removed from, and correcting the indirect measurement data and performing data fusion when system errors occur in the direct measurement data; and finally calculating credibility of fusion values. According to the technical scheme, the direct measurement data and the indirect measurement data are fused, the singular values, the measurement noise and the influence of the system errors are removed, the accuracy of the measurement data of the air conditioning load is effectively improved, the credibility of the fusion values is improved, and the reliability of controlling a water chilling unit is effectively improved.
本发明公开了一种建筑的空调负荷测量数据的融合方法,包括步骤:直接和间接测量空调负荷之后采集测量数据;当直接测量数据为奇异值,移除所述直接测量数据,使用间接测量数据进行数据融合;否则通过移动平均的方法移除所述采集的数据中的测量噪音后,将所述移除测量噪音后的数据进行数据融合,当直接测量数据存在系统误差,校正所述间接测量数据,进行数据融合;最后计算融合值的可信度。本发明的方案中,将直接测量数据与间接测量数据进行融合,移除奇异值、测量噪音及系统误差的影响,有效地提高空调负荷的测量数据的准确度,提高融合值的可信度,进而有效地提高冷水机组控制的可靠性。
