[0031] like Figure 1 As shown, a home appliance control system in one embodiment of the present invention includes a microphone module 10, a voice module 20, a display module 30, a control module 40, and a power module 50.

[0032] The control module 40 is connected to the microphone module 10 to receive voice control signals, communicates with the host computer to receive control signals, and is also connected to the voice module 20, display module 30, and home appliances. It controls the voice module 20 to play voice messages, controls the display module 30 to display information, and controls the home appliances based on the voice control signals or control signals. The power module 50 generates the necessary power voltage for the voice module 20, display module 30, and control module 40.

[0033] like Figure 2 As shown, the power module 50 includes a DC-DC conversion unit 51 and an LDO unit 52.

[0034] For example, the DC-DC conversion unit 51 includes a DC-DC chip U1 and its peripheral circuitry. The DC-DC conversion unit 51 is connected to the input voltage and converts the input voltage into a stable 5V power supply voltage.

[0035] LDO unit 52 includes LDO chip U3 and its peripheral circuitry. LDO unit 52 is connected to DC-DC converter unit 51 and is used to convert 5V power supply voltage to 3.3V power supply voltage. The preferred model of LDO chip U3 is RT9193.

[0036] In other embodiments, the power module 50 may be omitted, and the voice module 20, display module 30 and control module 40 may be supplied with power voltage directly through an external power source.

[0037] like Figure 3 As shown, the microphone module 10 includes a microphone (not shown) and a signal input circuit, which is connected to the microphone via connector CN4.

[0038] For example, the microphone has left and right channels, each a differential microphone, with a total of four voice control signal inputs (PL, NL, PR, NR). The signal input circuit has four inputs, each corresponding to one voice control signal. Taking the input corresponding to voice control signal PL as an example, the signal input circuit includes capacitor C30, a fourth resistor R15, and a TVS diode TVS5. The first terminals of capacitor C30, resistor R15, and TVS diode TVS5 are connected to the corresponding ports of the microphone to receive the voice control signal PL. The second terminal of capacitor C30 is connected to control module 40 to transmit the voice control signal PL to control module 40. The second terminal of resistor R15 is connected to the microphone bias voltage MICBIAS, which can be generated by control module 40. The second terminal of TVS diode TVS5 is connected to ground. The structure of the other three signal input circuits is the same as this signal input circuit.

[0039] like Figure 4 As shown, the control module 40 includes a control chip U3 and its peripheral circuitry. Specifically, the control chip U3 includes one or more of the following series chips: CI230X, CI23LC, CI13LC, CI13XX, CI231X, CI112X, and CI110X, preferably the CI2306 chip. This series of chips has a built-in WIFI module, enabling communication with a host computer (such as a mobile phone, tablet, or central control console) via WIFI. For example, the home appliance control system may also include a WIFI antenna, with pins 10 and 11 of the control chip U3 connected to the WIFI antenna to enhance the WIFI signal.

[0040] Pins 55 and 56 of control chip U3 are connected to LDO unit 52 in power module 50 to receive a 3.3V power supply voltage. Pins 20, 21, 23, and 24 of control chip U3 are connected to a signal input circuit to receive voice control signals PL, NL, PR, and NR, respectively. Control chip U3 can perform voice recognition on the voice control signals and extract the command information. Pin 22 of control chip U3 is connected to the signal input circuit to generate the microphone bias voltage MICBIAS.

[0041] In one embodiment, the home appliance control system may further include a button input module for generating an input signal SW. The control module is also connected to the button input module to control the voice module to play voice, control the display module to display, and control the home appliances based on the input signal SW.

[0042] For example, the key input module includes a switch SW1. The first end of the switch SW1 is connected to the ground voltage, and the second end of the switch SW1 is connected to pin 42 of the control chip U3. The switch SW1 generates an input signal SW based on its own switching state.

[0043] Pins 46 and 47 of the control chip U3 are connected to the home appliance to control it. Specifically, after receiving the voice control signal / control signal / input signal SW, the control chip U3 can directly forward the voice control signal / control signal / input signal SW to the home appliance. The home appliance's built-in hardware and program will then analyze and process the signal to implement the corresponding action. Alternatively, the control chip U3 can convert the voice control signal / control signal / input signal SW into a command signal that can directly control the home appliance and output the command signal to the home appliance. Either method is feasible for those skilled in the art.

[0044] Pin 43 of the control chip U3 is connected to the display module 30. After receiving the voice control signal / control signal / input signal SW, the control chip U3 can control the display module 30 to display based on the voice control signal / control signal / input signal SW.

[0045] Pins 33 and 36 of the control chip U3 are connected to the voice module 20. After receiving the voice control signal / control signal / input signal SW, the control chip U3 can control the voice module 20 to play voice based on the voice control signal / control signal / input signal SW. For example, the control chip U3 can store voice packets and select the corresponding voice from the voice packets based on the voice control signal / control signal / input signal SW to drive the voice module 20 to play.

[0046] like Figure 5 As shown, the display module 30 includes a light-emitting diode (LED) and a switching unit. The anode of the LED is connected to the DC-DC converter unit 51 to receive a 5V power supply voltage. The cathode of the LED is connected to the first terminal of the switching unit. The second terminal of the switching unit is connected to ground voltage. The switching unit is connected to the control module 40 to control the switching between the cathode of the LED and ground voltage based on the control of the control module 40.

[0047] The switching unit includes a first transistor Q1, a first resistor R39, a second resistor R40, and a third resistor R38. The first terminal of the first resistor R39 forms the first terminal of the switching unit and is connected to the cathode of the light-emitting diode. The second terminal of the first resistor R39 is connected to the second terminal of the first transistor Q1. The first terminals of the first transistor Q1 and the second resistor R40 are connected to ground to form the second terminal of the switching unit. The first terminal of the third resistor R38 is connected to the control terminal of the first transistor Q1. The second terminals of the second resistor R40 and the third resistor R38 are connected to pin 43 of the control chip U3.

[0048] In one embodiment, the first transistor is an NPN transistor.

[0049] When control chip U3 outputs a high level through pin 43, the first transistor turns on, and the LED emits light. When control chip U3 outputs a low level through pin 43, the first transistor turns off, and the LED does not emit light.

[0050] In other embodiments, the first transistor may also be a PNP transistor or other devices, in which case the connection method and control method of the first transistor are adapted accordingly.

[0051] like Figure 6 As shown, the voice module 20 includes a voice chip U6, a power amplifier unit, and a speaker SPEAKER.

[0052] Pins 1 and 3 of the voice chip U6 are connected to pins 33 and 36 of the control chip U3. Based on the control of the control chip U3, the voice chip U6 generates a voice signal through its own pin 6 to drive the speaker to play voice. The power amplifier unit is connected to pin 6 of the voice chip U6 and the speaker to amplify the voice signal and send it to the speaker to drive it to play voice.

[0053] For example, the voice chip U6 includes one or more of the NV040DS, NV080DS, NV170DS and NV340DS series, preferably NV170DS. Pin 5 of the voice chip U6 is connected to the DC-DC converter unit 51 to receive a 5V power supply voltage.

[0054] For example, the power amplifier unit includes a power amplifier chip U2 and its peripheral circuitry. Preferably, the power amplifier chip U2 is model 8002B.

[0055] Pin 1 of power amplifier chip U2 is connected to pin 37 of control chip U3. Control chip U3 can also output a mute signal through pin 37. Power amplifier chip U2 stops driving speaker SPEAKER to play voice based on the mute signal.

[0056] Pin 6 of the power amplifier chip U2 is connected to the DC-DC converter unit 51 to receive a 5V power supply voltage.

[0057] Pin 4 of the power amplifier chip is connected to pin 6 of the voice chip U6 to receive voice signals, and pins 5 and 8 of the power amplifier chip are connected to the speaker SPEAKER to drive the speaker SPEAKER to play voice.

[0058] In practical work, users can directly send control signals through host computers, such as mobile phones, tablets, and central control consoles, to achieve voice interaction, dynamic display, and home appliance control functions. They can also achieve convenient and flexible voice interaction through built-in apps and cloud platforms, such as weather and stock market forecasts, or setting reminders for customers based on time / weather, thus realizing a variety of online functions.

[0059] In offline mode, users can speak commands into the microphone as voice control signals, or generate input signals SW by pressing corresponding buttons. Then, the control module 40 can drive the voice module 20 to play corresponding voice responses based on these signals, realizing voice interaction. At the same time, it can control the display module to display lights, and can also control home appliances to perform corresponding actions such as turning them on and off.

[0060] This home appliance control system is compatible with both online and offline control of home appliances. It can meet the requirements of high reliability and low latency local voice control, as well as centralized management and complex logic control of the host computer, thereby improving the system's flexibility and availability.

[0061] This embodiment also provides a home appliance control module, including a circuit board on which the aforementioned home appliance control system is mounted.
