[0017] The present invention is further described below with reference to the embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0018] like Figure 1 and 2As shown, the utility model includes a remote control transmitting end circuit and a remote control receiving end circuit, the remote control receiving end circuit includes a wireless communication receiving chip, a relay and a driving circuit, the remote control receiving end circuit and the remote control transmitting end circuit are connected by wireless communication, the output end of the power supply is connected to the input end of the AC / DC power module, the power supply output end of the AC / DC power supply module is respectively connected to the power supply input end of the wireless communication receiving chip and the relay, the output end of the relay is connected to the input end of the driving circuit, and the output end of the driving circuit is connected to the output end of the wireless communication receiving core.

[0019] In this embodiment, a power collection module is provided on the power supply, and the output end of the power collection module is connected to the input end of the wireless communication receiving chip.

[0020] In this implementation example, the remote control transmitter circuit includes a wireless communication transmitter chip, the output end of the wireless communication transmitter chip is connected to the input end of the LCD screen, a key input end is provided on the wireless communication transmitter chip, and the wireless communication transmitter chip is wirelessly connected to the wireless communication receiving chip.

[0021] The live wire of the AC220V socket input power is LIN, and the neutral wire is NIN. LIN and NIN are divided into two paths, one is output after being electrocuted by the normally open contact of the relay, and the other is connected to the ACDC chip U3 to convert it into the DC power required by the control circuit.

[0022] The DC power supply first outputs DC12V to provide power for the relay coil. At the same time, DC12V is connected to the voltage regulator chip U4, and U4 is connected to the voltage regulator chip U1 to obtain +3.3V to power the wireless communication receiving chip, indicator light, and button circuit.

[0023] The wireless communication receiving chip U2 receives the wireless remote control signal of other LDSW remote controllers, and after being analyzed by the internal program, the output signal is connected to the transistor Q1. After being amplified, it controls the coil of the relay K1, so that the relay contacts are activated to realize the on and off of the AC220V power supply, thereby achieving the function of powering on and off the remote control socket.

[0024] The wireless communication receiving chip U2 simultaneously outputs a control signal, which is connected to the amplifiers Q2 and Q3 of the indicator light, and can control the on and off of the indicator light to realize the status indication function.

[0025] The wireless communication receiving chip U2 is also connected to the input signal of the button S1. When the button S1 is manually pressed, the wireless communication receiving chip receives the signal and can also control the on and off of the contacts of the relay to realize the power on and off function of the socket.

[0026] The working principle is as follows: Figure 1As shown, the smart socket is plugged into other sockets to obtain AC220V power, and obtains DC12V and DC3.3V power through the AC / DC power module. DC12V provides power for the relay coil, and DC3.3V provides power for the LDSW wireless communication chip. After receiving the wireless signal sent by the remote control transmitter, the LDSW wireless communication chip controls the drive circuit to connect the relay coil, so that the relay acts, the normally open node becomes closed, and the AC220V power can be connected to the power output end, thereby realizing the remote control of the socket. At the same time, the power acquisition module is connected to the power output end, which can detect the voltage, power, and power-on time, and transmit these parameters to the LDSW wireless communication chip, which is wirelessly transmitted to the remote control transmitter by the LDSW wireless communication chip. The remote control socket transmitter consists of the LDSW wireless communication chip, battery, LCD screen, and buttons.

[0027] like Figure 3 As shown, the battery provides power for the LDSW wireless communication chip and the LCD screen. After receiving the signal that the button is pressed, the LDSW wireless communication chip sends a wireless signal to the remote control socket receiving end, so that the socket is connected to the external output power. At the same time, the LDSW wireless communication chip at the transmitter end of the remote control socket receives the voltage, power and power-on time parameters sent back by the remote control socket receiving end, and drives the LCD screen for display.

[0028] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
