When there are some problems in the cloud server, network or a certain link of the entire data link, the smart adjustable socket will not be able to work normally.

[0006] Among them, the first problem mentioned above causes the intelligent regulating socket to be unable to meet customer needs in some applications; the second problem causes that there are no regulating sockets that can adjust fan load on the market; the third problem is that in some applications where strict requirements are placed on load control, when problems occur in the network or server, it may even lead to some serious consequences. Summary of the invention

[0007] The main purpose of the present invention is to provide an implementation method of an intelligent regulating socket and an intelligent regulating socket, aiming to solve the problem in the prior art that the intelligent regulating socket has a single function and cannot adjust the power of the connected load, especially the problem that it cannot adjust inductive loads such as fans, and also to solve the technical problem that the current intelligent regulating socket cannot be locally program-controlled and relies on the network for control.

[0008] To achieve the above object, the present invention provides a method for realizing an intelligent adjustment socket, wherein the intelligent adjustment socket includes an input unit, a voltage adjustment unit, an output unit, an internal power supply unit, a data storage, processing and control unit and a wireless communication unit, wherein:

[0009] The input unit is used to input AC power;

[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0049] Since the current intelligent regulating socket has a single function and cannot regulate the power of the subsequent load, especially the inductive load such as the fan, it cannot be well regulated and cannot meet the needs of users in different application scenarios. Moreover, its control instructions, timing instructions, etc. are all on the cloud server. When some problems occur in the cloud server, the network, or a certain link of the entire data link, the intelligent regulating socket cannot work normally. Therefore, the present invention proposes an intelligent regulating socket and a control method thereof.

[0050] The technical solution adopted by the intelligent adjustment socket and the control method of the present invention is mainly as follows: the intelligent adjustment socket includes an input unit, a voltage adjustment unit, an output unit, an internal power supply unit, a data storage, processing and control unit and a wireless communication unit.

[0051] The input unit is used to input AC power;

[0052] The internal power supply unit converts the AC power input by the input unit into low-voltage DC power to provide power for the voltage regulation unit, the data storage, processing and control unit and the wireless communication unit;

[0053] The wireless communication unit is used to exchange data with other smart terminals or the cloud and the user, and receive control information and setting information from the user;

[0054] The data storage, processing and control unit receives control data from the wireless communication unit or the local button, and controls the on and off of the AC switch in the voltage regulating unit according to the control information and setting information of the user, thereby changing the root mean square value of the output voltage connected to the output unit, and finally realizing intelligent adjustment of the output power of the intelligent adjustment socket;

[0055] The voltage regulating unit comprises at least two AC switches and a high-voltage capacitor, wherein at least one AC switch is connected in series with the high-voltage capacitor. The data storage, processing and control unit divides the voltage or performs phase cutting on the AC power input from the input unit according to the load type to be controlled by the intelligent regulating socket, and then outputs the AC power from the output unit;

[0056] The output unit is used to output the AC voltage processed by the voltage regulating unit to an external load.

[0057] This solution allows users to perform real-time control, programming control, preset control and other operations on the intelligent adjustment socket through the intelligent terminal. The operation information is stored in the local memory. The data storage and logic processing part adjusts and controls the voltage output by the socket according to the stored user control information and the time information of the local clock, and then the output power of the intelligent adjustment socket can be intelligently adjusted, which solves the problem that the current intelligent switches on the market cannot adjust the power of the connected load, and also solves the problem that the current intelligent cannot be programmed locally and relies on the network for control. At the same time, the present invention adopts a new circuit topology and dimming algorithm. When the intelligent adjustment socket is adjusting the lighting load, the adjustment of the light output is more in line with the user's expectations; when the intelligent adjustment socket is adjusting the fan and motor loads, the load output wind force and the motor output power are more in line with the user's expectations, and there is no additional noise.

[0059] like Figure 1 As shown, the intelligent adjustment socket proposed in this embodiment includes an input unit 10, a voltage adjustment unit 11, an output unit 12, an internal power supply unit 13, a data storage, processing and control unit 14, and a wireless communication unit 15.

[0060] The input unit 10 is connected to the voltage regulating unit 11 and the internal power supply unit 13 respectively; the voltage regulating unit 11 is also connected to the input unit 10, the data storage, processing and control unit 14 and the output unit 12 respectively; the internal power supply unit 13 is also connected to the input unit 10, the data storage, processing and control unit 14 and the wireless communication unit 15 respectively; the data storage, processing and control unit 14 is respectively connected to the voltage regulating unit 11, the internal power supply unit 13 and the wireless communication unit 15; the wireless communication unit 15 is respectively connected to the data storage, processing and control unit 14 and the internal power supply unit 13, and is wirelessly connected to the external user terminal for communication, and the output unit 12 is connected to the input unit 10.

[0061] Wherein, the input unit 10 is used to input AC mains. The internal power supply unit 13 is used to convert the AC mains into low-voltage DC power, and provide DC power supply and power zero-crossing information for the data storage, processing and control unit 14 and the wireless communication unit 15. The data storage, processing and control unit 14 is used to exchange data or information with the wireless communication unit 15, receive control information sent by the external user terminal, store it locally, and upload local data to the external user terminal; the data storage, processing and control unit 14 controls the AC switch in the voltage regulating unit 11 to turn on or off or controls the AC switch in the voltage regulating unit 11 to turn on or off the phase angle according to the information used for setting. The voltage output to the output unit 12 is adjusted, and finally the purpose of adjusting the power of the subsequent load is achieved.

[0062] Based on the above functional modules, this embodiment proposes a method for implementing an intelligent adjustment socket, wherein the intelligent adjustment socket includes an input unit, a voltage adjustment unit, an output unit, an internal power supply unit, a data storage, processing and control unit, and a wireless communication unit, wherein the input unit includes at least one AC input plug, the output unit includes at least one AC output jack, and the voltage adjustment unit includes at least two AC switches and a high-voltage capacitor, wherein at least one AC switch is connected in series with the high-voltage capacitor;

[0063] The implementation method of the intelligent adjustment socket comprises the following steps:

[0064] The input unit inputs AC power from the mains;

[0065] The internal power supply unit converts AC power from the mains into low-voltage DC power to provide power for the voltage regulation unit, the data storage, processing and control unit and the wireless communication unit;

[0066] The wireless communication unit exchanges data with the user and receives control information and setting information from the user;

[0067] The data storage, processing and control unit receives control data from the wireless communication unit or the local button, and controls the on and off of the AC switch in the voltage regulating unit according to the user's control information and setting information, thereby changing the root mean square value of the output voltage connected to the output unit, and finally realizing intelligent adjustment of the output power of the smart adjustment socket.

[0068] Figure 2 Schematic diagram of the working principle of the intelligent regulating socket embodiment of the present invention;

[0069] like Figure 2 As shown, the intelligent adjustment socket proposed in this embodiment includes an input unit 10, a voltage adjustment unit 11, an output unit 12, an internal power supply unit 13, a data storage, processing and control unit 14, and a wireless communication unit 15.

[0070] The AC mains power is input from the input unit 10, and the live wire and the neutral wire of the input unit 10 are output to the internal power supply unit 13. The internal power supply unit 13 converts the AC mains power into low-voltage DC power to provide DC power for the data storage, processing and control unit 14 and the wireless communication unit 15. At the same time, the internal power supply unit also detects the zero-crossing information of the input AC voltage and sends this information to the data storage, processing and control unit 14. The input unit also connects one line of the AC power (usually the neutral wire) to the output unit, and another line (usually the live wire) to the voltage regulation unit 11.

[0071] The voltage regulating unit 11 includes N AC switches 21 and M high-voltage capacitors 22. The AC switch uses a bidirectional thyristor, and the high-voltage capacitor uses an AC film capacitor. The AC switch and the high-voltage capacitor are connected in series to form a switch circuit, forming a switch circuit of M series high-voltage capacitors, where N=M+1, and there is an AC switch without a series high-voltage capacitor. The data storage, processing and control unit 14 controls the conduction and cutoff of one or more of the M series high-voltage capacitor switch circuits in the voltage regulating unit 11. Since the series high-voltage capacitor in the switch circuit of the M series high-voltage capacitors presents an impedance characteristic to the AC voltage, the mains voltage can be divided, thereby changing the voltage amplitude and root mean square value of the voltage output by the switch circuit, and finally realizing the output power of the intelligent adjustment socket to be adjusted in stages; or, the data storage, processing and control unit 14 controls the conduction and cutoff phase angle of the AC switch without a series high-voltage capacitor in the voltage regulating unit 11, and outputs the AC voltage in its circuit after phase cutting, thereby changing the root mean square value of the voltage output by the switch circuit, and finally realizing the continuous adjustment of the output power of the intelligent adjustment socket.

[0072] The data storage, processing and control unit 14 divides the voltage or performs phase cutting on the AC power input from the input unit according to the load type that the intelligent regulating socket needs to control and the user's control instructions, and then outputs it to the output unit 12, and the output unit 12 outputs it to the external load; the data storage, processing and control unit 14 receives data from the wireless communication unit 15, and controls the on and off states of the AC switch in the voltage regulating unit 11 according to the user's control information and setting information, thereby changing the root mean square value of the output voltage connected to the output unit, and finally realizing intelligent regulation of the output power of the intelligent regulating socket.

[0073] The data storage, processing and control unit 14 can adopt different voltage regulation methods according to the type of external load of the intelligent adjustment socket: when the inductive load is connected, the data storage, processing and control unit controls the conduction and cutoff of the AC switch in the high-voltage capacitor switch circuit in combination, divides the AC voltage in the switch circuit, and outputs a sinusoidal voltage with a reduced voltage amplitude to the output unit 12, wherein the voltage waveform of the input terminals A1 and A2 of the voltage adjustment unit 11 is a sinusoidal wave, such as Figure 3 As shown, the voltage waveforms of the output terminals B1 and B2 of the voltage regulating unit 11 are sinusoidal waves, such as Figure 4 When the intelligent adjustment socket is connected to a resistive or capacitive load, the data storage, processing and control unit 14 controls the phase angle of the AC switch 23 in the non-series high-voltage capacitor circuit to switch the AC voltage in the switch circuit, and outputs the voltage after the switching phase to the output unit 12, wherein the voltage waveform of the input terminals A1 and A2 of the voltage adjustment unit 11 is a sine wave, as shown in FIG. Figure 3 As shown, the voltage waveform of the output terminals B1 and B2 of the voltage regulating unit 11 is a sine wave phase-cut waveform, such as Figure 5 : Several typical waveforms of sine waves after phase cutting.

[0074] When the subsequent load is a lighting load, the data storage, processing and control unit 14 adjusts the subsequent load (i.e., the dimming light control process, the phase angle percentage of the AC switch cutoff and the adjustment step percentage in the user control information are exponentially related: y = 100-B*e^[-(a*x)],

[0075] Among them, a is a coefficient, greater than 0; B is a coefficient, greater than 0; e is a natural constant; y is the phase angle percentage of the AC switch cutoff, x is the adjustment step percentage, and the coefficients a and B are selected according to the smoothness of the adjustment curve; for the relationship curve between the specific phase percentage cut and the adjustment step percentage, please refer to Figure 6 .

[0076] The percentage of the AC switch conduction phase and the adjustment step percentage are in an exponential relationship: y1=B*e^[-(a*x)], 1; y1 is the percentage of the AC switch conduction phase, and the coefficients a and B are selected according to the smoothness of the adjustment curve.

[0077] The output unit 12 outputs the regulated AC voltage output by the voltage regulating unit 11 from the jack to the subsequent load, and the waveforms of its output terminals C1 and C2 are completely consistent with the waveforms of the output terminals B1 and B2 of the voltage regulating unit 11.

[0078] The internal power supply unit 13 is a switching power supply circuit that can complete AC to DC conversion. The internal power supply unit 13 can convert the input AC power into low-voltage DC power, for example, convert the input 220V AC power into 3.3V DC power, and provide DC power supply for the data storage, processing and control unit 14 and the wireless communication unit 15. At the same time, the internal power supply unit 13 will also detect the zero-crossing information of the mains power and send the information to the data storage, processing and control unit 14.

[0079] The data storage, processing and control unit 14 is generally composed of an MCU with a storage unit, or an MCU plus a storage chip. The data storage, processing and control unit 14 mainly completes functions such as data processing, storage, local logic processing, and function execution. The data storage, processing and control unit 14 exchanges data with the server or user terminal through the wireless communication unit 15, obtains the user's setting information or operation information for the intelligent adjustment socket, and stores the relevant data in the local memory, and also uploads the working status and device status of the intelligent adjustment socket to the user server or user terminal. The data storage, processing and control unit 14 controls the on or off phase state of the AC switch of the voltage adjustment unit 11 by analyzing and processing data such as user settings, preset programs, real-time operation information, local button operations, and local real-time time information, thereby controlling the AC voltage waveform output by the voltage adjustment unit 11, and achieving the purpose of intelligently adjusting the power of the subsequent load.

[0080] The wireless communication unit 15 can adopt a Bluetooth communication module or a WiFi communication module. The wireless communication unit 15 communicates with the data storage, processing and control unit 14 through a serial port, and at the same time communicates with the user terminal, or communicates with the cloud server through a wireless router to complete data exchange with the user terminal.

[0081] Specifically, the input unit 10 includes a 2-pin plug or a 3-pin plug.

[0082] The output unit 12 includes an AC output jack for connecting an external load.

[0083] The above 6 parts can form a complete intelligent adjustment socket, which can be used for intelligent dimming socket or intelligent speed regulation socket.

[0088] Figure 7 It is a schematic diagram of the working principle of the second embodiment of the intelligent adjustable socket of the present invention;

[0089] like Figure 7 As shown, the intelligent adjustment socket proposed in this embodiment includes an input unit 10, a voltage adjustment unit 11, an output unit 12, an internal power supply unit 13, a data storage, processing and control unit 14, a wireless communication unit 15, and a local indication and operation unit 16.

[0090] The AC mains power is input from the input unit 10, and the live wire L and the neutral wire N of the input unit 10 are output to the internal power supply unit 13. The internal power supply unit 13 converts the AC mains power into low-voltage DC power to provide DC power for the data storage, processing and control unit 14, the wireless communication unit 15 and the local indication and operation unit 16. At the same time, the internal power supply unit also detects the zero-crossing information of the input AC voltage and sends this information to the data storage, processing and control unit 14. The input unit also connects one line of the AC power (usually the neutral wire) to the output unit, and another line (usually the live wire) to the voltage regulation unit 11.

[0091] The voltage regulating unit 11 includes N AC switches 21 and M high-voltage capacitors 22. The AC switch uses a bidirectional thyristor, and the high-voltage capacitor uses an AC film capacitor. The AC switch and the high-voltage capacitor are connected in series to form a switch circuit, forming a switch circuit of M series high-voltage capacitors, where N=M+1, and there is an AC switch without a series high-voltage capacitor. The data storage, processing and control unit 14 controls the conduction and cutoff of one or more of the M series high-voltage capacitor switch circuits in the voltage regulating unit 11. Since the series high-voltage capacitor in the switch circuit of the M series high-voltage capacitors presents an impedance characteristic to the AC voltage, the mains voltage can be divided, thereby changing the voltage amplitude and root mean square value of the voltage output by the switch circuit, and finally realizing the output power of the intelligent adjustment socket to be adjusted in stages; or, the data storage, processing and control unit 14 controls the conduction and cutoff phase angle of the AC switch without a series high-voltage capacitor in the voltage regulating unit 11, and outputs the AC voltage in its circuit after phase cutting, thereby changing the root mean square value of the voltage output by the switch circuit, and finally realizing the continuous adjustment of the output power of the intelligent adjustment socket.

[0092] The data storage, processing and control unit 14 includes a local clock unit 31, which is composed of a real-time clock chip 41 and a super capacitor 42. When the intelligent adjustment socket is disconnected from the external power supply, the super capacitor 42 can provide a backup power supply for the clock chip 41, so that the time information in the local clock unit can be synchronized with the actual time, that is, real-time time information. The data storage, processing and control unit 14 exchanges data with the host computer or user terminal through the wireless communication unit 15, receives the control information sent by the host computer or user terminal, stores it locally, and uploads the local data to the host computer or user terminal; the data storage and logic processing unit is also used to communicate with the local clock unit, obtain local real-time time information, or update the data in the local clock. The data storage, processing and control unit 14 is also connected to the local indication and operation unit 16, receives the operation instructions from the local indication and operation unit, and controls the indicator light to indicate the working state of the intelligent adjustment socket. The data storage, processing and control unit 14 generates control program information based on the time axis according to the user control information, setting information from the wireless communication unit 15 or the user operation instructions from the local indication and operation unit 16, and reads the real-time clock information from the local clock unit 31, and further controls the conduction and cutoff changes of the AC switch in the voltage regulating unit 11, thereby dynamically changing the size of the root mean square value of the output voltage connected to the output unit, and finally realizing pre-programmable adjustment of the output power of the intelligent regulating socket.

[0093] The data storage, processing and control unit 14 can adopt different voltage regulation methods according to the type of external load of the intelligent adjustment socket: when the inductive load is connected, the data storage, processing and control unit controls the conduction and cutoff of the AC switch in the high-voltage capacitor switch circuit in combination, divides the AC voltage in the switch circuit, and outputs a sinusoidal voltage with a reduced voltage amplitude to the output unit 12, wherein the voltage waveform of the input terminals A1 and A2 of the voltage adjustment unit 11 is a sinusoidal wave, such as Figure 3 As shown, the voltage waveforms of the output terminals B1 and B2 of the voltage regulating unit 11 are sinusoidal waves, such as Figure 4 When the intelligent adjustment socket is connected to a resistive or capacitive load, the data storage, processing and control unit 14 controls the phase angle of the AC switch 23 in the non-series high-voltage capacitor circuit to switch the AC voltage in the switch circuit, and outputs the voltage after the switching phase to the output unit 12, wherein the voltage waveform of the input terminals A1 and A2 of the voltage adjustment unit 11 is a sine wave, as shown in FIG. Figure 3 As shown, the voltage waveforms of the output terminals B1 and B2 of the voltage regulating unit 11 are sinusoidal phase-cut waveforms, such as Figure 5 : Several typical waveforms of sine waves after phase cutting.

[0094] When the subsequent load is a lighting load, the data storage, processing and control unit 14 adjusts the subsequent load (i.e., the dimming light control process, the phase angle percentage of the AC switch cutoff and the adjustment step percentage in the user control information are exponentially related: y = 100-B*e^[-(a*x)],

[0095] Among them, a is a coefficient, greater than 0; B is a coefficient, greater than 0; e is a natural constant; y is the phase angle percentage of the AC switch cutoff, x is the adjustment step percentage, and the coefficients a and B are selected according to the smoothness of the adjustment curve; for the relationship curve between the specific phase percentage cut and the adjustment step percentage, please refer to Figure 6 .

[0096] The percentage of the AC switch conduction phase and the adjustment step percentage are in an exponential relationship: y1=B*e^[-(a*x)], 1; y1 is the percentage of the AC switch conduction phase, and the coefficients a and B are selected according to the smoothness of the adjustment curve.

[0097] The output unit 12 outputs the regulated AC voltage output by the voltage regulating unit 11 from the jack to the subsequent load, and the waveforms of its output terminals C1 and C2 are completely consistent with the waveforms of the output terminals B1 and B2 of the voltage regulating unit 11.

[0098] The internal power supply unit 13 is a switching power supply circuit that can complete AC to DC conversion. The internal power supply unit 13 can convert the input AC power into low-voltage DC power, for example, convert the input 220V AC power into 3.3V DC power, and provide DC power supply for the data storage, processing and control unit 14 and the wireless communication unit 15. At the same time, the internal power supply unit 13 will also detect the zero-crossing information of the mains power and send the information to the data storage, processing and control unit 14.

[0099] The data storage, processing and control unit 14 is generally composed of an MCU with a storage unit, or an MCU plus a storage chip. The data storage, processing and control unit 14 mainly completes functions such as data processing, storage, local logic processing, and function execution. The data storage, processing and control unit 14 exchanges data with the server or user terminal through the wireless communication unit 15, obtains the user's setting information or operation information for the intelligent adjustment socket, and stores the relevant data in the local memory, and also uploads the working status and device status of the intelligent adjustment socket to the user server or user terminal. The data storage, processing and control unit 14 controls the on or off phase state of the AC switch of the voltage adjustment unit 11 by analyzing and processing data such as user settings, preset programs, real-time operation information, local button operations, and local real-time time information, thereby controlling the AC voltage waveform output by the voltage adjustment unit 11, and achieving the purpose of intelligently adjusting the power of the subsequent load.

[0100] The wireless communication unit 15 can adopt a Bluetooth communication module or a WiFi communication module. The wireless communication unit 15 communicates with the data storage, processing and control unit 14 through a serial port, and at the same time communicates with the user terminal, or communicates with the cloud server through a wireless router to complete data exchange with the user terminal.

[0101] Specifically, the input unit 10 includes a 2-pin plug or a 3-pin plug.

[0102] The output unit 12 includes an AC output jack for connecting an external load.

[0103] The output unit 12 may be a 2-hole, 3-hole or 5-hole AC power socket, and the AC power outputted by the output unit 12 may be used for the AC load connected to the subsequent stage, such as a light bulb, a fan, etc.

[0104] The local indication and operation unit 16 generally includes buttons and indicator lights. The buttons are light touch buttons or touch buttons. The buttons can be used by users to start, clear, select local preset programs, and input function selections for network configurations; the indicator lights are LED indicator lights, LED digital tubes, or LCD display screens, which are used to indicate the working status of the intelligent adjustment socket and other information of the socket.

[0105] The above 7 parts can form a complete intelligent adjustment socket, especially an intelligent dimming socket and an intelligent speed regulating socket.

[0106] Figure 8 It is a schematic diagram of the third embodiment of the intelligent adjustment socket of the present invention; wherein P10 is a 2-pin plug of the input unit of the present invention, P10 is used for the access of the AC power of the intelligent adjustment socket, and the user generally inserts it into other power sockets during use; P11 is the shell of the intelligent socket, which is used to wrap all the circuit parts mentioned in the present invention; P12 is a 2-hole jack of the output unit of the present invention, the output of the user intelligent adjustment socket, and the user generally inserts its external load (such as a fan, an aerator, a floor lamp, a desk lamp, etc.) into the jack during use.

[0107] The following combination Figures 1 to 7 The present embodiment is further described with reference to the practical application scenarios.

[0108] For example, the user needs to preset the floor lamp in the bedroom, and the light will slowly light up from dark to bright within 5 minutes starting at 6:25 every morning, so that the user feels the morning sun rising. The user sets the demand in the APP in the smart phone, and the wireless communication unit 15 of the smart adjustment socket communicates with the user's smart phone, and transmits the user's preset program information to the data storage, processing and control unit 14 through the serial port. The data storage, processing and control unit 14 stores the data in the local storage unit, and starts to execute logic processing to start the local timing time. When the time read by the data storage, processing and control unit 14 from the local clock unit 4 is 6:25 in the morning, the data storage, processing and control unit 14 starts to control the voltage adjustment unit 11, and starts to conduct from the minimum phase angle, such as between 3% and 10%. In the next 5 minutes, the phase conduction angle percentage increases by 1 times per minute, and slowly rises to 100% in about 5 minutes. In this way, at the output end of the output unit 12 of the smart adjustment socket, its output AC voltage root mean square RMS value slowly rises, and the light output of the lighting load connected to it is consistent with the user's settings and expectations.

[0109] Figure 5 : The voltage waveforms of C1 and C2 at different brightness are: the output voltage waveforms of front cutting 80%, 50%, 20%, 0% and rear cutting 80%, 50%, 20%, 0%.

[0110] As an implementation method, the load connected to the intelligent adjustment socket is a lighting load such as an incandescent lamp, an LED lamp, a halogen lamp, etc., that is, the load needs to be dimmed. The voltage output after adjustment and the adjustment step are also nonlinear, showing an exponential relationship, or a quasi-exponential relationship. Figure 6As shown, during the dimming process, the phase percentage (phase percentage of the AC switch cut-off) and the adjustment step percentage are exponentially related. This relationship curve is basically consistent with the function y=100-B*e^[-(a*x)].

[0111] Among them, a is a coefficient, which is greater than 0; B is a coefficient, which is greater than 0; e is a natural constant, which is approximately equal to 2.718; y is the percentage of the phase cut, and x is the adjustment step percentage. Figure 6 In the figure, the ordinate is the percentage of the output voltage waveform phase (i.e. the phase percentage of the AC switch cut-off, 0 is the phase percentage of the AC switch cut-off 0%; 100 is the phase percentage of the AC switch cut-off 100%), and the abscissa is the percentage of the dimming step (0 is the dimming ratio 0%, i.e. the highest brightness; 100 is the dimming ratio 100%, i.e. the lowest brightness).

[0112] As another implementation, the load connected to the intelligent adjustment socket is a fan, a motor, etc., that is, the load needs to be speed-regulated. The speed regulator of the present invention is segmented, and when the number of high-voltage capacitor switch circuits in series in the voltage adjustment unit is N, the adjustment gear is N^2+1.

[0113] In summary, the implementation method of the intelligent adjustment socket of the present invention adopts a voltage adjustment method: the voltage adjustment unit includes several AC switch circuits with different functions, which can adjust the inductive load without phase cutting and only adjust the voltage in a segmented manner; the resistive and capacitive loads are continuously adjusted by phase cutting, which solves the problem that the current intelligent socket cannot adjust the subsequent load, and especially solves the problem that the fan speed cannot be adjusted without noise.

[0114] At the same time, the smart socket allows the user terminal to perform real-time control, programmed control, preset control and other operations on the smart adjusting socket. The operation information is saved in the local storage unit. The data storage and logic processing unit dynamically adjusts the subsequent load and programmable dynamic adjustment according to the stored user control information and the time information of the local clock, so that the intelligent control of the smart adjusting socket can be independent of the real-time communication of the network and the cloud server, which solves the problem that the current smart adjusting sockets on the market cannot adjust the power of the connected load, and also solves the problem that the current smart adjusting sockets cannot be locally programmed and rely on the network for control.

[0115] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
