4 is a flow chart 400 of a remote power control method according to another embodiment of the present invention, which is applicable to the remote power control system 100. As shown in FIG. 4, first, in step S410, the local end device 110 passes through the cloud server 120 to determine whether the remote device 130 is a slave device or a master device. If the remote device 130 is a slave device, the local device 110 transmits the power management request to the remote device 130 through the cloud server 120 (step S420). If the remote device 130 is the master device, the local device 110 transmits an access request to the remote device 130 through the cloud server 120 (step S430). When the remote device 130 accepts or does not respond to the access request of the local device 110, the remote device 130 is converted into a slave device, and the power management request of the local device 110 is transmitted to the remote device 130 through the cloud server 120 (step S440). When the remote device 130 rejects the access request of the local device 110, the local server 110 is notified through the cloud server 120 that the access request has been rejected by the remote device 130 (step S450).

According to an embodiment of the present invention, the remote device 130 is determined by the local end device 110 through the cloud server 120 in step S410. The slave device or the master device is based on the time of a timer. When the remote device 130 does not perform any action after the timeout expires, the remote device 130 is determined to be the slave device. When the remote device 130 has an action generated before the timeout period is terminated, the remote device 130 is judged as the master device.

Traditionally, when the local communication device accesses the data, the local device cannot control the power management of the remote device to turn off the remote device (making the remote device enter a sleep state or a standby state). Therefore, through the remote power control method proposed by the present invention, the local device can transmit the power management requirement to the remote device through the cloud server, and control the power state of the remote device to save power of the remote device. purpose.
