[0051] 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 with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0052] Because some technologies require different chips to transmit data for different refrigerator components, different chips need to be manufactured for different refrigerator components during the refrigerator development process, thereby increasing the manufacturing cost of the refrigerator. In order to solve this technical problem, this application provides a refrigerator communication data control system and method, which are described below:

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

[0054] Display controller 1 is disposed on the refrigerator door and is configured to: acquire refrigerator component control commands; the refrigerator component control commands are used to control the refrigerator components to open or close; the display controller 1 is a display screen disposed on the refrigerator door, through which the refrigerator's LED lights, heater, fan, compressor, damper, etc. can be controlled to open or close.

[0055] For example, users can communicate with the display controller 1 via Wi-Fi through mobile devices such as mobile phones, and remotely control the opening or closing of the refrigerator's LED lights, heaters, fans, compressors, and dampers through the mobile devices.

[0056] The main controller 2 is communicatively connected to the display controller 1. The main controller 2 is configured to: convert the format of the refrigerator component control command into the format of the refrigerator component receiving end according to the refrigerator component control command to obtain the target command; and control the refrigerator component to turn on or off according to the target command.

[0057] Understandably, a refrigerator's internal structure is complex, containing multiple operating components, such as LED lights for illumination, heaters to maintain a suitable internal temperature, fans to promote air circulation, compressors for the refrigeration system, and dampers to regulate cold air flow. These components each perform their specific functions, working together to ensure the refrigerator operates efficiently and stably. However, due to differences in their operating principles and electrical characteristics, each component requires specific control commands to be correctly activated or deactivated. Currently, to achieve precise control of these diverse components, the common practice is to place multiple independent control chips inside the refrigerator. Each chip is specifically designed to communicate with a particular refrigerator component, sending control commands that meet the component's receiving requirements. While this multi-chip design ensures precise control of each component, it also significantly increases manufacturing costs. These high costs not only raise the refrigerator's selling price and reduce its market competitiveness but also increase the complexity and resource waste in the production process.

[0058] To overcome the aforementioned problems, this application replaces the use of multiple chips by introducing a main controller 2. The main controller 2 can identify and process various refrigerator component control commands from the refrigerator management system or user interface; the main controller 2 can automatically adjust the format of the commands according to the type of refrigerator component to be controlled, ensuring that they are converted into a format that the receiving end of that component can recognize. The main controller 2 not only ensures accurate transmission of commands but also greatly simplifies the internal electrical structure of the refrigerator, avoiding the use of multiple chips. Through this approach, this application not only significantly reduces the manufacturing cost of the refrigerator, improves the product's cost-effectiveness and market competitiveness, but also reduces the complexity and resource waste in the production process.

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

[0060] In this embodiment, the refrigerator component control command and the target command include: a preamble, a data area, and an end code, such as... Figure 2 As shown; the data area contains several communication data; during communication, the complete structure of a data frame typically consists of three parts: a preamble, a data area, and an end-of-frame code, as shown below. Figure 2 As shown, the preamble code serves as a data transmission enable identifier. Decoding of subsequent data areas only begins after the received data is identified as a preamble code; otherwise, it is considered an interference signal and discarded until the preamble code data is identified again. The data area serves as an information carrier, identifying the communication data information it carries. The end code serves as a signal indicating the end of data transmission for this frame. Once the end code is identified, the receiving end will no longer receive data.

[0061] Depend on Figure 1 It is understood that the system further includes: a timer 3, which is communicatively connected to the display controller 1 and the main controller 2, and is configured to: adjust the time of the first and second guidance stages of the pre-code according to the data area, so that the transmission time of the refrigerator component control command is at its minimum; wherein, the transmission time of the pre-code is:

[0062] T Y =T YH +TYL ;

[0063] In the formula, T YH The first guidance phase time; T YL This refers to the timeframe for the second guiding phase. For example... Figure 3 As shown, the preamble includes two stages: a first stage and a second stage; the transmission time of the preamble = the first preamble stage time + the second preamble stage time, wherein the time ratio of the first preamble stage time and the second preamble 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 is understood that the data area includes a number of data 0s and data 1s; wherein, data 0s and data 1s also include two stages: a first stage and a second stage; the first stage of data 0s utilizes T 0H This indicates that the second stage of data 0 utilizes T 0L This indicates that the first stage of data 1 utilizes T. 1H This indicates that the second stage of data 1 utilizes T 1L It indicates that, based on the number of the first data area and the second data area, the time of the first target guidance stage and the second target guidance stage of the guide code are obtained; and the time of the first guidance stage and the second guidance stage of the guide code are adjusted according to the time of the first target guidance stage and the second target guidance stage of the guide code, so that the transmission time of the refrigerator component control command is at the minimum value.

[0067] For example, the time T of the preamble Y =T YH +T YL The transmission time is 10ms. As shown in the table below, the ratio of the first to second stages of the preamble and the ratio of the first to second stages of data 0 and data 1 are related. It can be seen that different ratios of the first and second stages of the preamble result in different transmission times for data 0 and data 1. For example, when the ratio of the first to second stages of the preamble is 1:1, the transmission time T for data 0 is... 0H =T 0L =1ms, T0=T 0H +T 0L =2ms, transmission time T of data 1 1H =3T 1L =3ms, T1=T 1H +T1L = 4ms; when the ratio of the first stage to the second stage of the preamble is 2:3, the transmission time T of data 0 is 4ms. 0H =T 0L =500us, T0=T 0H +T 0L =1ms, the transmission time T of data 1 1H =3T 1L =1.5ms, T1=T 1H +T 1L =2ms; when the ratio of the first stage to the second stage of the preamble is 4:1, the transmission time T of data 0 is 2ms. 0H =3T 0L =3ms, T0=T 0H +T 0L = 4ms, transmission time T of data 1 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 preamble according to the above ratio and the number of data 0 and data 1, so that the transmission time of the refrigerator component control command is minimized, thereby speeding up the transmission speed of the command.

[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 preamble is longer than the transmission time of the end code, and the transmission time of the end code is longer than the transmission time of the data area. The transmission time of the data area represents the transmission time of one unit of data 0 or one unit of data 1. The preamble has the longest transmission time and is used to synchronize the clock signals between the receiver and transmitter, ensuring that data is received in the correct timing. The end code's transmission time is between the preamble and the data area, used to identify the end of data transmission, helping the receiver determine when to stop receiving data; in some cases, it can also be used to verify data integrity or perform error detection. The data area has the shortest transmission time; 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 preamble; if the refrigerator component control instruction includes the preamble, then decode the data area. After the step of obtaining whether the refrigerator component control instruction includes the preamble, the method further includes: if the refrigerator component control instruction does not include the preamble, then delete the refrigerator component control instruction. During communication, the complete structure of a data frame typically consists of three parts: a preamble, a data area, and an end code, such as... Figure 2 As shown, the preamble code serves as a data transmission enable identifier. Decoding of subsequent data areas only begins after the received data is identified as a preamble code; otherwise, it is considered an interference signal and is deleted directly until the preamble code data is identified again. The data area serves as an information carrier, identifying the communication data information it carries. The end code serves as a signal indicating the end of data transmission for this frame. Once the end code is identified, the receiving end will no longer receive data.

[0071] For example, the primary task of the preamble is to help the receiver synchronize its clock with the transmitter. Clock synchronization is fundamental to ensuring accurate data transmission. By receiving and analyzing the preamble, the receiver can adjust its clock frequency and phase to match the transmitter. Furthermore, the preamble helps the receiver perform other necessary calibrations, such as gain and phase adjustments, to ensure that subsequent data is received and decoded optimally. Once the receiver successfully recognizes the preamble, it considers data transmission to have officially begun and triggers the subsequent data decoding process. This means that the receiver will only begin decoding the data area after confirming receipt of the preamble. In complex communication environments, the receiver may receive various interference signals. These interference signals may mimic real data transmission, misleading the receiver. However, because the preamble has a fixed pattern and characteristics, the receiver can use these characteristics to distinguish between genuine preambles and interference signals. If the receiver fails to recognize the preamble, it considers the currently received signal to be interference and discards it, helping to reduce the bit error rate and improve the reliability of data transmission.
