DETAILED DESCRIPTION

For a thorough understanding of the disclosure, numerous specific details are set forth in the following description for purposes of illustration but not of limitation, such as particularities of system structures, interfaces, techniques, et cetera.

FIG. 1 shows a flowchart of a mobile terminal-based method of controlling smart home appliances according to an embodiment of the disclosure. The method can be performed by a mobile terminal which is in a physical or wireless connection with an accessory and so receives state information of a user transmitted from the accessory. The method may comprise the following blocks.

In S101, the mobile terminal may receive the user state information from the accessory, the user state information being obtained through the accessory monitoring the user's sign parameters or environmental parameters.

After a communication connection is established between the mobile terminal and the accessory, the mobile terminal may receive the current state information of the user from the accessory. The user state information may be used to identify the state the user is currently in. The user state information may be obtained through the accessory monitoring the user's sign parameters or the environmental parameters. The user's current state may comprise sleep, non-sleep, et cetera.

The accessory of the mobile terminal may comprise, but is not limited to, a wearable device, or a device capable of monitoring the user sign parameters or the environmental parameters.

It will be appreciated that the accessory can transmit the user's current state information to the mobile terminal in real time or periodically according to a predetermined period, or transmit the current state information when detecting a change in the user state.

In S102, the method may include obtaining an operating mode of at least one smart home appliance.

The mobile terminal may obtain the operating mode of the at least one smart home appliance. The at least one smart home appliance may comprise, but is not limited to, one or more of a TV, speakers, and lights. Other smart home appliances can also be included, such as an air conditioner. The operating mode may comprise a normal mode and sleep mode.

Note blocks S101 and S102 can be executed in any order, for example, in parallel.

In S103, the method may include determining whether the operating mode of the at least one smart home appliance matches with the user state.

After obtaining the user's current state information and the operating mode of the at least one smart home appliance, the mobile terminal may determine whether the operating mode of the at least one smart home appliance matches with the user state. The user states may have a one-to-one correspondence with operating modes of the at least one smart home appliance. For example, when the user is in a non-sleep state, the corresponding operating mode of the at least one smart home appliance would be the normal mode. In contrary, when the user is in a sleep state, the corresponding operating mode of the at least one smart home appliance would be the sleep mode.

When the mobile terminal determines the operating mode of the at least one smart home appliance doesn't match with the user state, block S104 will be turned to; otherwise, no operation will be performed.

In S104, if the operating mode of the at least one smart home appliance doesn't match with the user state, the operating mode of the at least one smart home appliance may be adjusted based on the user state information.

After determining the operating mode of the at least one smart home appliance doesn't match with the user state, the mobile terminal may adjust the operating mode of the at least one smart home appliance to a corresponding operating mode of the current user state.

In particular, when the user is in the sleep state, the operating mode of the at least one smart home appliance will be adjusted to the sleep mode.

For example, when the user is in the sleep state while the at least one smart home appliance is in the normal mode, the operating mode of the at least one smart home appliance then may be converted from the normal mode to the sleep mode.

In contrary, when the user is in the non-sleep state while the at least one smart home appliance is in the sleep mode, the operating mode of the at least one smart home appliance then may be switched from the sleep mode to the normal mode.

Further, if the at least one smart home appliance comprises one or more of a TV, speakers, and lights, then adjusting the operating mode of the at least one smart home appliance to the sleep mode when the user is in the sleep state may comprise: turning down a volume of the TV or speakers, or reducing a brightness of the lights.

For example, when the user is in the sleep state, the volume of the TV and speakers may be turned down, and the brightness of the lights may be reduced. Alternatively, all of the TV, speakers, and lights may be completely turned off.

According to the above embodiment, the mobile terminal can determine whether the operating mode of a smart home appliance matches with the user state, and, if they don't match, adjust the operating mode of the smart home appliance to a corresponding operating mode of the current user state. Thus, the operating mode of the smart home appliances can be adjusted in real time in accordance with the user state.

As such, the present embodiment can improve the energy efficiency and at the same time provide a suitable and comfortable environment for the user.

Further, the user state may be determined based on the user sign parameters or environmental parameters in combination with correspondences between the user sign parameters or environmental parameters and states of the user.

For example, the accessory may refer to a database to determine the user state corresponding to the user sign parameters or the environmental parameters.

The data base may store in advance the correspondences between the user sign parameters or environmental parameters and the user states, or may contain a survey report of the correspondences between the user sign parameters or environmental parameters with the user states.

In S203, the user state information may be transmitted to the mobile terminal, so that the mobile terminal may determine whether to adjust the operating mode of the at least one smart home appliance according to the user state information.

After determining the user state, the accessory may transmit the user state information to the mobile terminal, thus the mobile terminal can determine whether it needs to adjust an operating mode of at least one smart home appliance based on the user state information and the operating mode of the at least one smart home appliance.

It will be appreciated that the accessory can transmit the user's current state information to the mobile terminal in real time or periodically according to a predetermined period, or transmit the current state information when detecting a change in the user state.
