Transcritical carbon dioxide refrigeration data simulation system

The invention relates to the technical field of data processing, in particular to a transcritical carbon dioxide refrigeration data simulation system which comprises the steps that original data are collected through refrigeration equipment, and sample spaces of a refrigeration end and a compression end of a refrigeration system are established; carrying out self-adaptive updating on the observation noise matrix through abnormal data in the sample space; predicting the observation data of the next moment according to the latest collected observation data to obtain a prediction result, and performing simulation according to the prediction result. According to the method, the outlier difference between the fusion result in the simulation model and the noise data is constructed through the monitoring data, and the noise matrix is adaptively updated. The description accuracy of the observation noise matrix in the prediction process of the EKF is optimized, and the optimization effect on the simulation model accor
