This application is about a method for determining the operating status of equipment based on a smart park and a big data center. Applying the scheme of this application, the first step is to determine the j group of equipment operating parameters corresponding to the i production equipment, the second step is to generate a parameter list based on the equipment type information of the i production equipment and the operating period parameters of the j group of equipment operating parameters, and the third step The first step is to perform feature extraction on the parameter list to obtain the feature list, and the fourth step is to correct the state feature vector with the largest state weight in each target list unit based on the j group of equipment operating parameters of each production equipment to obtain the corresponding operation of each production equipment state vector. By correcting the state eigenvector with the largest state weight to eliminate the influence between production equipment, noise removal can be achieved when determining the operating state vector, and the working state of each production equipment can be accurately determined to reduce the difficulty of production equipment scheduling.
