Description
Technical Field
[0001] This utility model relates to the field of air conditioning control technology, and in particular to a control circuit for an air conditioning control system. Background Technology
[0002] With the rapid development of smart home technology, the limitations of traditional air conditioning control systems are becoming increasingly apparent. Most existing air conditioning systems still rely primarily on physical buttons for operation, requiring users to directly manipulate buttons on the control panel to adjust parameters such as temperature, fan speed, and mode. This simplistic control method not only limits user convenience but also increases inconvenience, especially at night or in low-visibility conditions.
[0003] With the development of technology and the increasing demands of consumers, users are increasingly expecting more intelligent and diverse control methods. While button control is direct, it lacks flexibility and interactivity, making it difficult to meet the expectations of modern families for smart homes. Therefore, developing an air conditioning control system that can break through the constraints of traditional button control and integrate more advanced control technologies is particularly important.

Subsequently, the main control module sends the generated air conditioning system main control signal to the button control module. In the button control module, the relay K' plays a crucial role. When the main control module sends a control signal to the second terminal of the negative coil of the relay K', the relay coil is activated, thereby indirectly sending a control signal to the switch button J' through the change in the current of the relay coil. Specifically, since button J' is electrically connected to the fourth normally closed terminal of relay K', the circuit connected to button J' and the fourth normally closed terminal of relay K' will be turned on.

[0043] In addition to voice control, users can also directly control the air conditioning system using button J' on the button control module. When the user presses button J', since button J' is connected to the normally closed terminal of relay K, pressing the button will control the operation of the air conditioning system.
[0044] In summary, this control circuit combines voice control and button control to provide users with a flexible and diverse operating experience for the air conditioning system. Whether using voice commands or physical buttons, users can easily control the air conditioning system. Attached Figure Description

[0060] The button control module 1 includes a relay K' and a button J'. The fourth terminal of the relay K' is a normally closed terminal, the third terminal of the relay K' is a normally open terminal, the first terminal of the relay K' is a common terminal, the fifth terminal of the relay K' is the positive terminal of the relay coil, and the second terminal of the relay K' is the negative terminal of the relay coil.
[0061] The button J' is electrically connected to the fourth terminal of the relay K', the first terminal of the relay K' is grounded, the fifth terminal of the relay K' is electrically connected to the power supply voltage VCC, and the second terminal of the relay K' is electrically connected to the main control module 3.
[0062] like Figure 1 As shown, when a user issues a voice command, the voice recognition module 2 is responsible for collecting these voice signals and processing and recognizing them using a built-in algorithm. Once the user's intention, such as adjusting the temperature or changing the fan speed, is recognized, the voice recognition module 2 sends this command to the main control module 3 in the form of an electrical signal. Then, after receiving the command from the voice recognition module 2, the main control module 3 processes these commands according to preset program logic and generates a corresponding air conditioning system main control signal, containing the specific parameters and commands required to control the air conditioning system. Subsequently, the main control module 3 sends the generated air conditioning system main control signal to the button control module 1. In the button control module 1, the relay K' plays a crucial role. When the main control module 3 sends a control signal to the second terminal of the negative coil of the relay K', the relay coil is activated, thereby indirectly sending a control signal to the switch button J' through the change in the current of the relay coil. Specifically, since button J' is electrically connected to the fourth normally closed terminal of relay K', the circuit connected to button J' and the fourth normally closed terminal of relay K' will be turned on. These control signals are then used to adjust the operating status of the air conditioning equipment, such as turning it on and off, adjusting the temperature, or starting the fast cooling mode, thereby realizing the control of the corresponding functions of the air conditioning system.
[0063] In addition to voice control, users can also directly control the air conditioning system using button J' on button control module 1. When the user presses button J', since button J' is connected to the normally closed terminal of relay K, pressing the button will control the operation of the air conditioning system.
[0064] In summary, this control circuit combines voice control and button control to provide users with a flexible and diverse operating experience for the air conditioning system. Whether using voice commands or physical buttons, users can easily control the air conditioning system.
[0065] Further explanation includes the air conditioner light control module 4, the first serial communication module 5, and the second serial communication module 6;
[0066] The output terminal of the main control module 3 is also electrically connected to the input terminal of the first serial communication module 5, the output terminal of the first serial communication module 5 is electrically connected to the input terminal of the second serial communication module 6, the output terminal of the second serial communication module 6 is electrically connected to the input terminal of the air conditioner light control module 4, and the output terminal of the air conditioner light control module 4 is electrically connected to the air conditioner light LED.
[0067] The main control module 3 is used to process user voice commands to generate air conditioner light main control signals, and send them to the air conditioner light control module 4 through the first serial communication module 5 to control the display status of the air conditioner light LED;
[0068] The air conditioner light control module 4 is used to receive the air conditioner light main control signal from the main control module 3 through the second serial communication module 6, so as to control the display status of the air conditioner light LED.
[0069] In the expanded air conditioning control system circuit, in addition to the original button control module 1, voice recognition module 2, and main control module 3, an air conditioning light control module 4, a first serial communication module 5, and a second serial communication module 6 have been added. This expansion enables the system to simultaneously control the operation of the air conditioning system and the display status of the air conditioning LED lights.
[0070] After the user issues a voice command, the voice recognition module 2 collects, processes, and recognizes these commands, and sends the recognition results to the main control module 3. Based on the received commands, the main control module 3 not only processes control signals related to the air conditioning system but also generates a main control signal for the air conditioning lights. Subsequently, the main control module 3 sends the main control signal for the air conditioning lights to the air conditioning light control module 4 via the first serial communication module 5 in a serial communication manner. The first serial communication module 5 is responsible for converting the digital signal output by the main control module 3 into a format suitable for serial communication and sending it to the second serial communication module 6. The air conditioning light control module 4 receives the main control signal for the air conditioning lights from the main control module 3 via the second serial communication module 6. The second serial communication module 6 performs the opposite operation to the first serial communication module 5, that is, converting the received serial communication signal back into a digital signal and transmitting it to the air conditioning light control module 4 for processing. Based on the received main control signal, the air conditioning light control module 4 controls the display status of the air conditioning light LEDs, such as changing the color, brightness, or display mode.
[0071] To further explain, the button control module 1 includes a switch control submodule, a temperature increase control submodule, a temperature decrease control submodule, and a rapid cooling control submodule;
[0072] The switch control submodule includes a relay K1 and a switch button J1;
[0073] The fourth terminal of relay K1 is the normally closed terminal of the relay, the third terminal of relay K1 is the normally open terminal of the relay, the first terminal of relay K1 is the common terminal of the relay, the fifth terminal of relay K1 is the positive terminal of relay coil, and the second terminal of relay K1 is the negative terminal of relay coil.

[0078] The temperature reduction control submodule includes a relay K3 and a switch button J3;
[0079] The fourth terminal of relay K3 is the normally closed terminal of the relay, the third terminal of relay K3 is the normally open terminal of the relay, the first terminal of relay K3 is the common terminal of the relay, the fifth terminal of relay K3 is the positive terminal of relay coil, and the second terminal of relay K3 is the negative terminal of relay coil.

Specifically, the positive terminal of the relay coil is connected to the power supply voltage VCC, and the negative terminal is connected to the main control module 3, forming a circuit. Since the normally closed terminal 4 of the relay is connected to the common terminal 1 of the relay, a control signal is indirectly sent to the switch buttons J1, J2, J3, and J4 through the change in current in the relay coil. These control signals are then used to adjust the operating status of the air conditioning equipment, such as turning it on / off, adjusting the temperature, or activating the fast cooling mode.

[0088] like Figure 3 As shown, when a user issues a voice command, the sound travels through the air to microphone MIC1. Microphone MIC1 converts the sound signal into an electrical signal and transmits it to the voice recognition chip U2 via its MIC+ and MIC- terminals, which are typically positive and negative. These two ports ensure accurate capture and transmission of the sound signal.
[0089] Next, after receiving the electrical signal from microphone MIC1, the voice recognition chip U2 performs a series of signal processing operations, including amplification, filtering, and noise reduction, to improve the quality and clarity of the voice signal. These processing steps help ensure that the voice recognition algorithm can accurately recognize the user's voice commands.
[0090] Finally, the processed speech signal is sent to the built-in algorithm of the speech recognition chip U2 for recognition. This algorithm compares the user's speech signal with a preset speech model to identify what the user is saying. Once recognition is successful, the chip generates corresponding control signals or commands.
[0091] To further explain, the main control module 3 includes a main control chip U1, and the main control chip U1 is model ESP8266MOD;
[0092] As an optional embodiment, when the main control chip U1 adopts the ESP8266MOD model, the core processing unit of the control circuit of the air conditioning control system receives strong support. This is because the ESP8266MOD is a highly integrated Wi-Fi SoC system-on-a-chip, which not only has a complete TCP / IP protocol stack, but also has a built-in low-power 32-bit CPU, providing high-performance network processing capabilities.
[0093] It should be noted that any chip capable of collecting, processing, and recognizing user voice commands is within the protection scope of this utility model.

The D0 terminal of the main control chip U1 is electrically connected to the second terminal of the relay K1.
[0095] like Figure 4 As shown, when a user issues a voice command, the sound travels through the air to microphone MIC1. Microphone MIC1 converts the sound signal into an electrical signal and transmits it to the voice recognition chip U2 via its MIC+ and MIC- terminals to ensure accurate capture and transmission of the sound signal. After receiving the electrical signal from microphone MIC1, voice recognition chip U2 performs a series of signal processing operations, including amplification, filtering, and noise reduction, to improve the quality and clarity of the voice signal. These processing steps help ensure that the voice recognition algorithm can accurately recognize the user's voice commands. The processed voice signal is then fed into the built-in algorithm of voice recognition chip U2 for recognition. This algorithm compares the user's voice signal with a preset voice model to identify what the user is saying. Once recognition is successful, voice recognition chip U2 generates the corresponding control signal or command.
[0096] Furthermore, in order to provide operational feedback to the user, the voice recognition chip U2 can also drive the speaker B1 to emit sounds through its SPK+ and SPK- terminals.
