Claim 6:
7. The control method of the remote-control system according to claim 4, further comprising: switching, by the first wireless communication circuit, a first ultra-wideband transceiver of the remote controller from a sleep state to a working state when the received signal strength indication is greater than or equal to the strength threshold; switching, by the second wireless communication circuit, a second ultra-wideband transceiver of the controlled device from a sleep state to a working state when the received signal strength indication is greater than or equal to the strength threshold; measuring, by the second ultra-wideband transceiver that is in the working state, a distance between the remote controller and the controlled device; determining, by the second ultra-wideband transceiver that is in the working state, whether or not the distance is within a preset distance range; and detecting, by the second wireless communication circuit, the operational state of the controlled device when the distance is within the preset distance range.
