[0035] refer to Figure 1-Figure 5 The first aspect of the present invention provides a smart socket, comprising a socket housing and a PCB board arranged in the socket housing, wherein the 3D exploded view of the smart socket is as shown in FIG. Figure 1 As shown, the structure of the PCB board is as follows Figure 2 As shown, it includes a communication PCB board 1 and a drive PCB board 2, and the communication PCB board 1 and the drive PCB board 2 are connected through a pin header 6; wherein,

[0036] The structure of the communication PCB board 1 is as follows Figure 3 As shown, the communication PCB board 1 is provided with a microcontroller 11, and the structure of the driving PCB board 2 is as shown in FIG. Figure 4As shown, the driving PCB board 2 is provided with a live and neutral main circuit, which includes a live input and output circuit, a neutral input and output circuit, and a relay and drive circuit 25; the live input and output circuit and the neutral input and output circuit are respectively connected to the relay and drive circuit 25;

[0037] The driving PCB board 2 is also provided with an electricity meter module 26 and a plurality of detection resistor branches, one end of each detection resistor branch is connected to the electricity meter module 26, and the other end of each detection resistor branch is connected to the relay and the driving circuit 25;

[0038] The relay and drive circuit 25 and the power meter module 26 are respectively connected to the microcontroller 11 through the pin headers 6 .

[0039] Specifically, the smart socket's communication PCB 1 and driver PCB 2 are positioned opposite each other, with an insulating sheet 3 positioned between them. Both have connectors at the same relative position, connected by pin headers 6. After welding, they form a single component: communication PCB / insulating sheet / driver PCB—the PCB. The socket housing also includes a top shell 4 and a bottom shell 5. The PCB and bottom shell 5 are screwed together, and the top shell 4 and bottom shell 5 are snap-fitted together. The microcontroller 11 (MCU) in the communication PCB 1, also known as a single-chip microcomputer, is used to process, store, and compare data, generate, and issue commands, and can be implemented with modules such as the 87C51, 8051, 89C51, RTL8723DS, CB2S, ESP32, and QCA9531.

[0040] See also Figure 4 , the live wire input and output circuits in the driving PCB board 2 are the live wire input circuit 21 and the live wire output circuit 22, and the neutral wire input and output circuits are the neutral wire input circuit 23 and the neutral wire output circuit 24, wherein the live wire input circuit 21, the live wire output circuit 22, the neutral wire input circuit 23, and the neutral wire output circuit 24 are used to connect to the electrical equipment or to the ground, and the electrical equipment is connected to the smart socket; the relay and drive circuit 25 is responsible for switching the switch on and off, and can adopt ULN2003, HK4100F-DC5V-SH, etc.; the power meter module 26, that is, the power meter IC, is used to measure, count, transmit and detect data anomalies, and can compare the real-time usage data of the electrical equipment with its stored threshold conditions. When the real-time usage data exceeds the threshold condition, a square wave pulse signal is output and sent to the microcontroller 11 together with the working status data of the electrical equipment. The power meter module 26 can adopt ADE7755, ADE7753, ADE7763, etc.

[0041] The internal circuit connections of the PCB board are as follows Figure 5 As shown, the driver PCB 2 is also equipped with multiple detection resistor branches embedded in the live and neutral main circuits to divide the circuit voltage, allowing the power meter module 26 to collect device power usage information and usage information, such as switch status, usage duration, voltage, current, and power. When the relay and the relay in the driver circuit 25 are closed, the live input - (detection resistor) - relay - detection resistor - live output form the live main circuit. The neutral main circuit is formed similarly, thus changing the "open-loop control" of the traditional smart switch to "closed-loop control." The relay and drive circuit 25 and the power meter module 26 in the drive PCB board 2 are connected to the microcontroller 11 in the communication PCB board 1 through the pin header 6. After the electrical equipment is connected to the smart socket through the live and neutral wires, the relay and drive circuit 25 switch the switch on and off according to the control of the microcontroller 11 in the communication PCB board 1. After the relay is closed, the voltage signal generated by the switch status, usage time, voltage, current, power and other information of the electrical equipment is transmitted to the power meter module 26. The power meter module 26 transmits the signal to the microcontroller 11 in the communication PCB board 1 through the pin header 6 to identify the working status of the electrical equipment; at the same time, the microcontroller 11 can also generate a shutdown command based on the data abnormality detection result of the power meter module 26 and send it to the relay and drive circuit 25 to switch the relay on and off, so as to shut down the smart socket when the electrical equipment is used abnormally.

[0042] In one embodiment, the communication PCB board 1 also includes an LDO power supply 12, which is connected to the microcontroller 11; the drive PCB board 2 also includes a power conversion module 27, and the live wire input circuit 21, the neutral wire input circuit 23, the relay and drive circuit 25 and the power meter module 26 are respectively connected to the power conversion module 27; the power conversion module 27 is connected to the LDO power supply 12 through a pin header 6.

After the LDO power supply 12 is connected to the power conversion module 27, it supplies power to each module on the communication PCB board 1 and the driver PCB board 2. The AC-to-DC power supply is a 12V power conversion chip, which can be AH8640, AH8966, SM7025, etc. In addition, when the microcontroller 11 receives a square wave pulse signal representing an abnormality sent by the power meter module 26, it generates a pipe section instruction and sends it to the power conversion module 27 or the relay and drive circuit 25 to control the power supply to stop supplying power or control the relay and drive circuit 25 to switch, thereby realizing the management of high-power electrical appliances. Smart switches and power detection are also integrated into the smart socket to better understand the working status of electrical equipment and better protect the equipment.

[0044] In one embodiment, the communication PCB board 1 further includes an infrared communication module 13 , which is connected to the LDO power supply 12 and the microcontroller 11 respectively. The infrared communication module 13 includes a built-in infrared emitting tube 131 and an external infrared emitting tube 132 .

[0045] See also Figure 3 The communication PCB 1 also includes an infrared communication module 13, or infrared IC, which drives the infrared emitting diode and transmits signals when the operating level of an electrical appliance needs to be switched. Infrared communication module 13 is compatible with both internal and external infrared emitting diodes 131 and 132, and can utilize IR LEDs, STX610A modules, and other devices. The addition of infrared control to the communication PCB 1 in this application further enhances the compatibility of the smart socket.

[0046] In one embodiment, the communication PCB board 1 further includes a temperature comparison module 14, which is respectively connected to the LDO power supply 12 and the microcontroller 11; the driving PCB board 2 further includes a thermistor, which is connected to the temperature comparison module 14 through the pin 6.

[0047] See also Figure 3The communication PCB board 1 is also provided with a temperature comparison module 14, i.e., a temperature comparison IC, which is used in conjunction with the thermistor NTC in the driver PCB board 2. The present application collects the temperature data of the electrical equipment during use through the thermistor and sends it to the temperature comparison module 14 and the microcontroller 11 via the pin header 6. The temperature comparison module 14 compares the temperature data with the standard value. When the temperature data exceeds the standard value range, it generates a corresponding voltage signal and sends it to the microcontroller 11 as a feedback judgment condition, so that the smart socket stops working when the operating temperature of the electrical equipment is too high or too low. The temperature comparison module 14 can adopt DS18B20, etc. The smart socket of the present application adds temperature detection, which can not only better understand the working status of the electrical equipment, but also ensure the safety of the equipment.

Universal 86-style wall switches or external socket switches have different interface formats, and the live / neutral interface must be compatible with the switch interface.

[0051] In one embodiment, the detection resistor branch includes a voltage detection resistor and a current detection resistor. The voltage detection resistor is connected in parallel with the live and neutral main circuit, and the voltage detection resistor is connected in series with the live and neutral main circuit.

[0052] See also Figure 5 The detection resistor branch includes a voltage detection resistor and a current detection resistor. For detailed connections, please refer to Figure 5; Among them, the voltage detection resistor is connected in parallel to the live and neutral main circuit, and after multiple resistors divide the voltage, the proportionally reduced voltage signal is transmitted to the power meter module 26; the current detection resistor is connected in series to the live and neutral main circuit. The detection resistor has a very small resistance and will not consume too much electricity. When the relay is closed, the live input-(detection resistor)-relay-detection resistor-live output forms a loop, and the detection resistor produces a voltage drop, which transmits a small voltage signal to the power meter module 26. The power meter module 26 transmits the signal to the microcontroller 11 on the communication PCB board 1 through the pin 6. After receiving the feedback information, the microcontroller 11 performs internal calculations to obtain the usage status data of the electrical equipment to identify the working status of the electrical equipment.
