Embodiment Construction
[0042] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0043] The object of the present invention is to provide an easy-to-use, safe, wire-saving, and expansible household power supply control circuit and its control method. The digital signal conversion circuit board 3, the multi-way switch can be arranged on the panel switch 1. One side of this conversion circuit board 3 is connected with a common household panel switch 1 (single key or multi-key), and the other side is connected with a driver 2 through a two-core weak current circuit, so as to realize power supply control of household electrical appliances such as lighting and curtains through the driver 2 .

The invention discloses a power control circuit and a control method thereof. The power control circuit includes a panel switch, an actuator, and a conversion circuit board arranged in the panel switch; the actuator is used for accessing to an external alternating current, converting the alternating current into a first direct current, and transmitting the first direct current to the conversion circuit board; the actuator is also used for sending a control signal based on a data signal to output a safe alternating current; the conversion circuit board is used for receiving a switch signal of the panel switch in the state of accessing to the first direct current and converting the switch signal into a data signal, and sending the data signal to the actuator. The beneficial effects of the power control circuit and the control method thereof are that: the security of the panel switch during use can be ensured by pulling a weak electric wire to the panel switch, the replacement of the panel switch is more convenient, strong electric wires can be saved, and the wiring cost is saved; in addition, due to a weak current system, the intelligent home appliance system can be easily achieved, and the expansibility is strong.
Description
technical field [0001] The invention relates to the field of home appliance power control, in particular to a power control circuit and a control method thereof. Background technique [0002] There are two basic control methods for smart home appliance power supply, wireless and wired. Although the wireless control saves wires, the stability of the control is poor, and it is not suitable for the home decoration industry; for the existing wired switch control method, see figure 1 , figure 1 In the traditional control method, the live wire must be pulled from the incoming line to the switch, and then pulled to the lamps and other electrical equipment through the switch contact, which requires a long and strong wire to connect to the switch node. And the strong wires are all thicker copper wires, the price is higher, and the wiring is complicated, the strong and weak currents are mixed, the safety is poor, and the wires are wasted. Contents of the invention [0003] The te...
