Overview
This invention introduces an electrical appliance usage state analysis device and method. Based on the correlation between appliance state sequence data and electricity meter sequence data, appliances are categorized into high-correlation and low-correlation groups. For high-correlation appliances, training is conducted using the first-type model based on their state sequence data and electricity meter sequence data. For low-correlation appliances, features are extracted to produce appliance state feature data and meter feature data, which are then combined with user information feature data and trained using the second-type model. This method remains applicable even at low sampling frequencies. Even when the data sampling rate is below 1 Hz, the resulting models still provide accurate analysis results, addressing the limitations of NILM technology in analyzing low-frequency sampled data.Category
