Multi-input distributed non-intrusive load decomposition method

The invention relates to the technical field of non-intrusive load decomposition, and provides a multi-input-based distributed non-intrusive load decomposition method, which comprises the following steps of: acquiring a plurality of load parameters as input data, and preprocessing to obtain a low-frequency multi-parameter input space and a high-frequency parameter input space; inputting the low-frequency multi-parameter input space into a low-frequency multi-channel feature extraction module, and synchronously inputting the high-frequency parameter input space into a high-frequency feature extraction module; the low-frequency multi-channel feature extraction module outputs a low-frequency feature map, and the high-frequency feature extraction module outputs a high-frequency feature map; and performing element summation on the low-frequency feature map and the high-frequency feature map to form a new high-dimensional feature map, generating a fusion space containing high-frequency and low-frequency features by
