[0050] This solution provides one or more functional modules 2, and the functional modules 2 are connected to the main control board 1. The main control board 1 can be used to control the functional modules 2 to perform corresponding functions according to the received second control information. In a possible embodiment, the functional modules 2 provided by this solution include a combination of one or more of a drying rod lifting module 21, a lighting module 22, a disinfection module 23, an air-drying module 24 and a drying module 25, which are respectively used to realize the functions of the drying rod lifting, lighting, disinfection, air-drying and drying of the clothes drying machine.

There is no need to change the function module 2 and related settings for different types of remote control devices 5. While reducing the cost and difficulty of circuit development, it effectively realizes flexible and accurate control of the clothes drying machine and improves user experience.

[0051] Optionally, the remote control device 5 can determine the corresponding control parameters according to the functional module 2 to be controlled, generate the first control information based on the control parameters and the corresponding first communication protocol, and send the first control instruction to the control module 3 through the corresponding first communication protocol. After receiving the first control information, the control module 3 parses the first control information to determine the target functional module to be controlled indicated by the first control information and the control parameters for controlling the target functional module, and generates the second control information based on the control parameters and the corresponding second communication protocol, and sends the second control information to the main control board 1. The main control board 1 parses the second control information based on the second communication protocol to determine the target functional module to be controlled indicated by the second control information and the control parameters for controlling the target functional module, and controls the target functional module to perform the corresponding function based on the control parameters.

[0052] In one embodiment, when the control module 3 generates the second control information based on the control parameters and the corresponding second communication protocol, it can be performed according to the control command frame format corresponding to the second communication protocol. For example, the control command frame format records the protocol header, protocol frame length, control frame number, remote control device number, control function, checksum and protocol tail at different byte positions, wherein the protocol header can be understood as the beginning of the protocol, so that the receiver knows that this is the beginning of the protocol, the protocol frame length can be understood as the length of the protocol, the control frame number can be understood as the control command number sent to the main control board, starting from 1 when power is turned on, and the number increases by 1 for each message sent until it reaches 10,000 and then starts again from 1, the numbering can enable the main control board to accurately respond to each protocol, the remote control device number can be understood as the specific remote control device controlled, the control function can be understood as the function performed by the control function module, the checksum can be understood as the verification for whether there is an error after the receiver receives the entire data, and the protocol tail can be understood as the end of the protocol, so that the receiver knows that this is the end of the protocol.

[0053] For example, the byte length corresponding to the second control information is 8. The protocol header (for example, 0xAA) can be recorded at the 0-byte position, the protocol frame length (for example, 8) can be recorded at the 1-byte position, the control frame number (for example, 1 to 10000) can be recorded at the 2-3-byte position, and the remote control device number can be recorded at the 4-byte position (for example, 0x01 indicates an RF433 remote control, 0x02 indicates an infrared remote control, 0x03 indicates a Bluetooth remote control, 0x04 indicates a mobile phone applet (can be connected via the WiFi protocol), 0x05 indicates a mobile phone APP (can be connected via the WiFi protocol), 0x06 indicates offline voice, and 0x07 indicates online voice). The control function is recorded at the 5-byte position (for example, 0x01 indicates that the clothes-drying rod rises, 0x02 indicates that the clothes-drying rod rises, 0x03 indicates that the clothes-drying rod stops, 0x04 indicates that the clothes-drying rod rises a little, 0x05 indicates that the clothes-drying rod drops a little, 0x06 indicates turning on the lighting, 0x07 indicates turning off the lighting, 0x08 indicates turning on disinfection, 0x09 indicates turning off disinfection, 0x0A indicates turning on air drying, 0x0B indicates turning off air drying, 0x0C indicates turning on hot air, 0x0D indicates turning off hot air, and 0x0E indicates that all functions are turned off). The checksum is recorded at the 6-byte position (for example, a checksum with a checksum value of 0-5 bytes), and the protocol tail is recorded at the 7-byte position (for example, 0xFB). The second control information is generated by a standardized control command frame format, which enables the main control board to respond to control information quickly and accurately without making overall changes to the main control board, thereby enriching the operation methods of the clothes-drying machine.

[0054] like Figure 7As shown in the principle block diagram of a clothes drying control circuit with a newly added receiving module, when it is necessary to add a remote control device 5 of a different type and communication protocol (for example, the newly added device 1 and the newly added device 2 in the figure), a corresponding receiving module 4 (for example, the newly added module 1 and the newly added module 2 in the figure) can be added to the clothes drying control circuit according to the communication protocol corresponding to the newly added remote control device 5. The control module 3 can establish a connection with the newly added remote control device 5 through the newly added receiving module 4, and receive the first control information sent by the newly added remote control device 5 based on the corresponding first communication protocol through the newly added receiving module 4, convert the first control information into the second control information based on the second communication protocol and send it to the main control board 1, the main control board 1 can respond to the corresponding control information normally, there is no need to change the main control board 1, and it only needs to connect the corresponding receiving module 4 in the control module 3.

[0055] In the above, the remote control device 5 is connected based on the preset first communication protocol through the receiving module 4, and the first control information sent by the remote control device 5 based on the first communication protocol is received, and the first control information is sent to the control module 3. The first control information is converted into second control information based on the preset second communication protocol by the control module 3, and sent to the main control board 1. The main control board 1 can control the functional module 2 of the clothes drying machine to perform the corresponding function according to the second control information, and different receiving modules 4 can receive the first control information sent by different types of remote control devices 5 based on different communication protocols, and the control module 3 can convert the first control information into the second control information that the main control board 1 can correctly identify and process.
