Abstract: Embodiments of this application provide a signal processing method, it includes: a secondary node obtains first data and a plurality of pieces of second data; then, the secondary node determines a plurality of first similarity degrees based on the first data and the plurality of pieces of second data; and then, the secondary node determines a target primary node based on the plurality of first similarity degrees. The first data is power frequency cycle feature data collected by the secondary node in a target time period, the plurality of pieces of second data are power frequency cycle feature data respectively collected by a plurality of primary nodes in the target time period.
