To further describe the working method of the household appliance control system, in a second aspect, an embodiment of the present application further provides a household appliance control method, as shown in fig. 10, the method includes the following steps:

step S701: the external device generates a peripheral signal.

In this embodiment, the external device refers to a device connected to the smart board, such as a first external device connected to the first input function interface of the smart board and a third external device connected to the first input/output function interface of the smart board. Accordingly, the peripheral signal may include a first peripheral signal generated by the first external device and/or a third peripheral signal generated by the third external device.

After the household appliance is started, the external equipment can generate an external signal, and the intelligent board can collect the external signal from the external equipment connected with the intelligent board.

For example, the household appliance is an air conditioner, and the first external device comprises a voice recognition module. The user sends a voice command of 'quick refrigeration', the quick refrigeration is first peripheral information, and the voice recognition module recognizes the first peripheral information to generate a first peripheral signal.

In the case where there is no external signal, the smart board may control the home appliance only based on an internal signal from the driver board. For example, after the air conditioner is turned on, if the user does not send a voice command, the air conditioner can automatically operate according to the internal signal collected by the driving board, such as an ambient temperature signal.

Step S702: the driver board generates an internal signal.

After the household appliance is started, the drive board can acquire parameter signals of the first functional component and/or the third functional component in the household appliance through the second input functional interface, and the parameter signals are subjected to logic processing to obtain built-in signals.

For example, for an air conditioner, the drive board includes an air conditioner external unit drive board and an air conditioner internal unit drive board, the device capable of acquiring signals in the air conditioner external unit and the air conditioner internal unit may include a first functional component and a third functional component, the parameter information obtained by the drive board according to the first functional component and the third functional component may include an indoor environment temperature, an indoor coil temperature, an outdoor environment temperature, an outdoor coil temperature, a compressor exhaust temperature, and the like, and the parameter information is processed to obtain an internal signal.

Step S703: the intelligent board obtains input signals, and the input signals comprise peripheral signals and internal signals.

The first controller of the intelligent board can acquire a first peripheral signal forwarded by the air conditioner display board, the wire controller or the wireless communication module through the first input function interface, and can acquire an internal signal generated by the driving board and a third peripheral signal from third peripheral equipment through the first input/output function interface.

In this embodiment, the peripheral signal acquired by the smart board is the first peripheral signal.

Step S704: an output signal is generated from the input signal.

The first controller of the intelligent board can perform input logic operation on the first peripheral signals through a built-in first input processing logic and algorithm to obtain first peripheral information; performing input logic operation on a third peripheral signal through a built-in first input/output control logic and algorithm to obtain third peripheral information; and performing input logic operation on the built-in signal through a first input/output control logic and algorithm to obtain parameter information from the drive board.

The first controller calculates the comprehensive parameter information, the first peripheral information and/or the third peripheral information through the household appliance function control logic and algorithm to obtain first control information, second control information and/or third control information.

The first controller can carry out output logic operation on the first control information through a built-in first output processing logic and algorithm to obtain a first control signal; performing output logic operation on the second control information through a built-in first output processing logic and algorithm to obtain a second control signal; and carrying out output logic operation on the third control information through a built-in first input/output control logic AND algorithm to obtain a third control signal.

For example, the first controller of the smart board obtains the current running state of the household appliance according to the parameter information, obtains the user requirement according to the first peripheral information, and can calculate the first control information and the second control information by using the function control logic and the algorithm. The first control information may include information such as the rotation speed of the motor of the internal machine, the rotation speed of the motor of the external machine, the frequency of the compressor, the opening of the four-way valve, and error information. The second control information may include voice information such as "rapid cooling mode setting success".

Furthermore, the intelligent board can judge whether the household appliance has a fault according to whether the parameter information is in a preset threshold range, and if the household appliance has the fault, a fault signal is generated and sent to the display board, so that the display board can display a fault code according to the fault signal; and the intelligent board judges whether equipment such as a motor of an air conditioner external unit, a motor of an air conditioner internal unit, a compressor and the like can also run according to the preset fault level to which the fault belongs, and if the equipment can also run, the next action is executed.

Step S705: and sending a peripheral control signal to the external equipment, and sending a first control signal to the drive board.

The second control signal and the third control signal both belong to the peripheral control signal. The smart board may transmit a first control signal to the driving board through the first input/output function interface, transmit a third control signal to a third external device through the first input/output function interface, and transmit a second control signal to the second external device through the first output function interface.

Furthermore, the first controller of the intelligent board can also generate display information of the air conditioner panel, such as information of a refrigeration mode, set/ambient temperature, wind speed and the like, according to the parameter information, the first peripheral information and the third peripheral information, further generate a display signal according to the display information, and send the display signal to the air conditioner display panel, so that the air conditioner panel can display the display information.

In this embodiment, the smart board sends a first control signal to the driver board and sends a second control signal to the second external device.

Step S706: and the external equipment executes corresponding actions according to the peripheral control signals.

The second external device may perform a logic operation on the second control signal to obtain second control information, and execute a corresponding action according to the second control information. The third external device may perform a logical operation on the third control signal to obtain third control information, and perform a corresponding action according to the third control information.

In this embodiment, the speaker may play the voice information according to the second control information: "the quick cooling mode setting is successful".

Further, if the third external device is a device that needs to send a feedback signal to the smart board, such as a speed-adjustable motor, the smart board may further determine whether the third external device fails according to whether the feedback signal of the third external device is received within a preset time or whether the feedback signal meets a preset signal range, and if the third external device fails, the smart board may further send the failure information of the third external device to the air conditioner display panel for display.

Step S707: the driving board controls the household appliance according to the first control signal.

And after receiving the first control signal, the driving board obtains first control information through logical operation, and drives the second functional component and/or the third functional component of the household appliance to operate according to the first control information.

In this embodiment, the driving board of the air conditioner outdoor unit drives the air supply motor to operate at a set rotation speed according to the first control information, drives the compressor to operate at a set frequency, drives the four-way valve to switch to a set direction according to a setting, drives the electronic expansion valve to open to a set opening degree, and the like, and detects an outdoor environment temperature, a coil temperature, a compressor exhaust temperature, a compressor return air temperature, and the like in real time.

Further, the driving board can generate new built-in signals for the parameter information of the second functional component and/or the third functional component to be used by the intelligent board for performing household appliance function control operation and controlling the air conditioner display board to update display information.

In a third aspect, an embodiment of the present application provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed, the method for controlling a home appliance according to the second aspect is implemented.

According to the embodiment, the control of the household appliance is realized by splitting the control of the household appliance to the intelligent board and the drive board, the first controller of the intelligent board is used for generating the first control signal, the first control signal is sent to the drive board, and the drive board processes the first control signal and then controls the second functional component and/or the third functional component in the household appliance, so that the function control of the household appliance is realized. A function control algorithm for performing function control on the household appliance does not need to be arranged in the second controller of the drive board, so that the functional structure of the drive board is simplified, and the application range of the drive board is favorably improved; and the intelligent board acquires the built-in signal with the parameter information of the first functional component and/or the third functional component in the household appliance according to the driving board, and the intelligent board is directly connected with various first functional components and/or third functional components in the household appliance without setting various interfaces, so that the intelligent board can be expanded to different types, different manufacturers, and even different types of household appliances, and is strong in universality. Furthermore, an interface connected with external equipment can be further arranged on the intelligent board, and the function expansion and upgrading of the household appliance are facilitated.
