[0051] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0052] In some technologies, different chips are required to complete data transmission for different refrigerator components, which results in the need to manufacture different chips for different refrigerator components during refrigerator development, thereby increasing the manufacturing cost of refrigerators. In order to solve this technical problem, the present application provides a refrigerator communication data control system and method. The refrigerator communication data control system and method are described below:

[0053] Depend on Figure 1 It can be seen that the first aspect of the present application provides a refrigerator communication data control system, including:

[0054] Display controller 1, the display controller 1 is arranged on the refrigerator door, and the display controller 1 is configured to: obtain refrigerator component control instructions; the refrigerator component control instructions are used to control the refrigerator components to be turned on or off; the display controller 1 is a display screen arranged on the refrigerator door, and the LED lights, heaters, fans, compressors, dampers, etc. of the refrigerator can be controlled to be turned on or off through the display screen.

[0055] For example, a user can communicate with the display controller 1 via Wi-FI through a mobile device such as a mobile phone, and can remotely control the refrigerator's LED lights, heater, fan, compressor, damper, etc. to turn on or off through the mobile device.

[0056] A main controller 2, wherein the main controller 2 is communicatively connected with the display controller 1, and the main controller 2 is configured to: according to the refrigerator component control instruction, convert the format of the refrigerator component control instruction into the format of the refrigerator component receiving end to obtain a target instruction; according to the target instruction, control the refrigerator component to be turned on or off.

[0057] It is understandable that the internal structure of the refrigerator is complex and contains multiple operating components, such as LED lights for lighting, heaters to maintain a suitable internal temperature, fans to promote air circulation, compressors for compression refrigeration systems, and dampers to adjust the circulation of cold air. These components perform their respective duties and work together to ensure that the refrigerator can operate efficiently and stably. However, due to the different working principles and electrical characteristics of each component, it is necessary to receive control instructions in a specific format to be correctly turned on or off. At present, in order to achieve precise control of these diverse components, it is common practice to set up multiple independent control chips inside the refrigerator. Each chip is specially designed to communicate with a specific refrigerator component and send control instructions that meet the receiving requirements of the component. Although this multi-chip design can ensure that each component is precisely controlled, it also brings about a significant increase in manufacturing costs. The high cost not only increases the selling price of the refrigerator and reduces the market competitiveness of the product, but also increases the complexity and waste of resources in the production process.

[0058] In order to overcome the above problems, the present application introduces a main controller 2 to replace the setting of multiple groups of chips. The main controller 2 can identify and process various refrigerator component control instructions from the refrigerator management system or user interface; the main controller 2 can automatically adjust the format of the instruction according to the type of refrigerator component to be controlled by the instruction, ensuring that it is converted into a format that can be recognized by the receiving end of the component. The setting of the main controller 2 not only ensures the accurate transmission of the instruction, but also greatly simplifies the electrical structure inside the refrigerator and avoids the use of multiple groups of chips. In the above manner, the present application not only significantly reduces the manufacturing cost of the refrigerator, improves the cost performance and market competitiveness of the product, but also reduces the complexity and waste of resources in the production process.

[0059] Depend on Figure 1 It can be seen that the main controller 2 includes: a format converter 21, which is communicatively connected to the display controller 1, and the format converter 21 is configured to: according to the refrigerator component control instruction, convert the format of the refrigerator component control instruction into the format of the refrigerator component receiving end to obtain the target instruction; the format converter 21 can automatically adjust the format of the instruction according to the type of refrigerator component to be controlled by the instruction, and ensure that it is converted into a format that can be recognized by the receiving end of the component. The control unit 22 is communicatively connected to the format converter 21, and the control unit 22 is configured to: according to the target instruction, control the refrigerator component to be turned on or off.

[0060] In this embodiment, the refrigerator component control instruction and the target instruction include: a boot code, a data area, and an end code. Figure 2 As shown in the figure, the data area contains several communication data. During the communication process, the complete structure of a frame of data usually consists of three parts: the leading code, the data area, and the ending code. Figure 2 As shown, the guide code is used as a transmission data enable identifier. When the received data is determined to be a guide code, the decoding of the subsequent data area is started. Otherwise, it is considered to be an interference signal and is directly discarded until the next guide code data is determined. The data area is used as an information carrier to identify the communication data information carried. The end code is used as an end signal for sending the data of this frame. When it is determined to be the end code, the receiving end will no longer receive data.

[0061] Depend on Figure 1 It can be seen that the system further includes: a timer 3, which is in communication with the display controller 1 and the main controller 2 and is configured to: adjust the time of the first boot phase and the second boot phase of the boot code according to the data area, so that the transmission time of the refrigerator component control instruction is at a minimum value; wherein the transmission time of the boot code is:

[0062] T Y =T YH +TYL ;

[0063] Where, T YH is the first boot phase time; T YL is the time of the second boot phase. Figure 3 As shown, the boot code includes two stages: the first stage and the second stage; the transmission time of the boot code = the first boot stage time + the second boot stage time, wherein the time ratio of the first boot stage time and the second boot stage time is different, and the transmission time of the data area is also different.

[0064] In this embodiment, the data area includes: a first data area and a second data area; the first data area represents data 0, and the second data area represents data 1.

[0065] The timer 3 is further configured as follows:

[0066] Obtain the number of the first data area and the second data area in the data area; it can be understood that the data area includes a number of data 0 and data 1; wherein data 0 and data 1 also include two stages: the first stage and the second stage; the first stage of data 0 uses T 0H Indicates that the second stage of data 0 uses T 0L Indicates that the first stage of the data 1 uses T 1H Indicates that the second stage of data 1 uses T 1L Indicates; according to the number of the first data area and the second data area, obtain the time of the first target boot phase and the second target boot phase of the boot code; according to the time of the first target boot phase and the second target boot phase of the boot code, adjust the time of the first boot phase and the second boot phase of the boot code so that the transmission time of the refrigerator component control instruction is at the minimum value.

[0067] For example, the boot code time T Y =T YH +T YL The ratio of the first and second phases of the boot code to the ratio of the first and second phases of data 0 and data 1 in the following table shows that when the ratio of the first and second phases of the boot code is different, the transmission time of data 0 and data 1 is different. For example, when the ratio of the first and second phases of the boot code is 1:1, the transmission time of data 0 is T 0H =T 0L =1ms, T0=T 0H +T 0L =2ms, data 1 transmission time T 1H =3T 1L =3ms, T1=T 1H +T1L =4ms; When the ratio of the first stage to the second stage of the boot code is 2:3, the transmission time of data 0 is T 0H =T 0L =500us, T0=T 0H +T 0L =1ms, data 1 transmission time T 1H =3T 1L =1.5ms, T1=T 1H +T 1L =2ms; When the ratio of the first stage to the second stage of the boot code is 4:1, the transmission time of data 0 is T 0H =3T 0L =3ms, T0=T 0H +T 0L =4ms, data 1 transmission time T 1H =T 1L =1ms, T1=T 1H +T 1L =2ms; the timer 3 can flexibly adjust the ratio of the first stage and the second stage of the boot code according to the above-mentioned proportional relationship and the number of data 0 and data 1, so that the transmission time of the refrigerator component control instruction is at the minimum value, thereby speeding up the transmission speed of the instruction.

[0068] <![CDATA[T YH :T YL ]]> <![CDATA[T 0H :T 0L ]]> <![CDATA[T 1H :T 1L ]]> 1:1 <![CDATA[T 0H =T 0L =1ms]]> <![CDATA[T 1H =3T 1L =3ms]]> 2:3 <![CDATA[T 0H =T 0L =500us]]> <![CDATA[T 1H =3T 1L =1.5ms]]> 4:1 <![CDATA[T 0H =3T 0L =3ms]]> <![CDATA[T 1H =T 1L =1ms]]>

[0069] In this embodiment, the transmission time of the guide code is greater than the transmission time of the end code, and the transmission time of the end code is greater than the transmission time of the data area, wherein the transmission time of the data area represents the transmission time of 1 unit of data 0 or 1 unit of data 1. The transmission time of the guide code is the longest, and is used to synchronize the clock signal between the receiver and the transmitter to ensure that the data is received at the correct timing. The transmission time of the end code is between the guide code and the data area, and is used to mark the end of the data transmission and help the receiver determine when to stop receiving data; in some cases, it can also be used to verify the integrity of the data or perform error detection. The transmission time of the data area is the shortest, and the data area is the part that actually transmits information and contains the specific data that needs to be sent and received.

[0070] In this embodiment, the timer 3 or the main controller 2 is further configured to: obtain whether the refrigerator component control instruction includes the boot code; if the refrigerator component control instruction includes the boot code, decode the data area. After the step of obtaining whether the refrigerator component control instruction includes the boot code, it also includes: if the refrigerator component control instruction does not include the boot code, delete the refrigerator component control instruction. In the communication process, the complete structure of a frame of data is usually composed of three parts: the boot code, the data area, and the end code. Figure 2 As shown, the guide code is used as a transmission data enable identifier. When the received data is determined to be a guide code, the decoding of the subsequent data area will be started. Otherwise, it is considered to be an interference signal and is directly deleted until the next guide code data is determined. The data area is used as an information carrier to identify the communication data information carried. The end code is used as an end signal for sending the data of this frame. When it is determined to be the end code, the receiving end will no longer receive data.

[0071] Exemplarily, the primary task of the guide code is to help the receiver and the transmitter achieve clock synchronization. In the process of data transmission, clock synchronization is the basis for ensuring that data is transmitted accurately and without error. By receiving and analyzing the guide code, the receiver can adjust its own clock frequency and phase to keep it consistent with the transmitter. In addition, the guide code also helps the receiver to perform other necessary calibration work, such as gain adjustment, phase adjustment, etc., to ensure that subsequent data can be received and decoded in the best state. When the receiver successfully recognizes the guide code, it will consider that the data transmission has officially started, and trigger the subsequent data decoding process accordingly. This means that only after confirming that the guide code has been received, the receiver will start decoding the content of the data area. Among them, in a complex communication environment, the receiver may receive various interference signals. These interference signals may imitate real data transmission, thereby misleading the receiver. However, since the guide code has fixed patterns and characteristics, the receiver can use these characteristics to distinguish between real guide codes and interference signals. Once the receiver fails to successfully identify the guide code, it will consider the currently received signal to be an interference signal and directly discard it, which helps to reduce the bit error rate and improve the reliability of data transmission.
