1. A communication method applied to an intelligent device, wherein the intelligent device comprises a plurality of sensors, and the method comprises:
determining N target sensors from the plurality of sensors, wherein Nis an integer greater than 1;
determining clock frequency offsets between respective clocks of the N target sensors and a first clock and determining respective transmission delays of the N target sensors based on a preset time synchronization protocol; and
performing time synchronization on the N target sensors based on the clock frequency offsets between the respective clocks of the N target sensors and the first clock, and the respective transmission delays of the N target sensors;
wherein the determining of the N target sensors from the plurality of sensors comprises:
determining, from the plurality of sensors based on M target sensors and a preset fusion rule, N−M target sensors configured to perform data fusion with the M target sensors, wherein the M target sensors belong to the N target sensors, M is an integer greater than or equal to 1, and the N−M target sensors belong to the N target sensors.
