This thing networking house power supply control system 10 can realize the control and the control of the house power supply of direct current and interchange simultaneously to the convenience and the security of thing networking house system have further been promoted.

Further, as shown in fig. 3, in the internet of things household power supply control system 10 of the present application, the power supply device 110 further includes a dc voltage regulator 119.

Specifically, the dc voltage regulator 119 is connected between the ac/dc converter 117 and the second switch 118, and is configured to regulate the voltage of the dc power output by the ac/dc converter 117. At this time, the current in the grid 20 is converted into dc power by the ac/dc converter 117, and then flows into the dc voltage regulator 119. The dc voltage regulator 119 regulates the dc voltage, and outputs the regulated dc voltage to the dc power supply 116 through the second switch 118. Thus, the dc power supply 116 can supply dc power having a voltage set by the dc voltage regulator 119.

Further, the dc power supply 116 includes a dc socket and a Universal Serial Bus (USB) interface.

The third communicator 146 is connected to the second controller 144, and the third communicator 146 is also communicatively connected to the second communicator. Thus, when the first controller 124 sends the second control signal through the second communicator, the third communicator 146 may acquire the second control signal and transmit the second control signal to the second controller 144. The second controller 144 controls the operation of the operation device 142 according to the second control signal.

More specifically, as is known from the above description, the control signal sent by the on-screen display device 130 and received by the central control apparatus 120 is named as the first control signal. For the sake of distinction, the control signal sent by the central control device 120 and received by the household appliance 140 is named as the second control signal. In other words, the second control signal is a control signal transmitted to the home appliance 140 by the central control device 120.

In the present embodiment, when the user wants to change the operating state of the household appliance 140, for example, to increase the heating temperature of the air conditioner or decrease the cooling temperature of the refrigerator, the first control signal can be sent out through the screen display device 130.
