Description

Technical Field

[0001] This invention belongs to the field of refrigerator control technology, and in particular relates to a communication control method for a WIFI refrigerator. Background Technology

[0002] As people's living standards improve, more and more home appliances are entering ordinary households, bringing great convenience to people's lives. Refrigerators have now become an indispensable home appliance, and most refrigerators now have network connectivity, making it convenient for users to manage them independently. For example, they can monitor the refrigerator's operating status in real time and then send the data to the user's mobile device.

[0003] Currently, data exchange is achieved by connecting the display and control board to the WIFI module using standard serial port functionality. However, due to the diverse structural designs of refrigerators, this direct connection between the display board and the WIFI module has certain limitations. Issues such as the strong electromagnetic signals of refrigerators and the poor anti-interference capability of serial signals can affect the communication and data transmission of the entire machine. Summary of the Invention

[0004] The purpose of this invention is to provide a communication control method for a WIFI refrigerator. By setting an inverter board to forward data from the display and control board and the WIFI module, the refrigerator network data transmission is realized. This compensates for the inability of the display board and the WIFI module to be directly connected, forming a new data transmission link and communication control mode, thus solving the refrigerator communication problem.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a communication control method for a WIFI refrigerator, comprising the following steps:

[0007] Step 1: Power on and initialize the refrigerator;

[0008] Step 2: The frequency converter board receives data from the display and control board and the WIFI module, and the frequency converter board communicates periodically with the display and control board and the WIFI module respectively.

[0009] Step 3: The inverter board receives WIFI data and determines the command type, which includes query commands and setting commands. If the command type is a query command, it jumps to step 2 and communicates according to the normal timing sequence. If the command type is determined to be a setting command, it needs to jump to step 4.

[0010] Step four: After receiving the WIFI module setting command, the frequency converter board forwards it to the display and control board, then receives the data returned by the display and control board and replies with WIFI data.

[0011] Preferably, in step two, the communication link between the frequency converter board and the display and control board is link 1, and the communication link between the frequency converter board and the WIFI module is link 2.

[0012] Preferably, the frequency converter board acts as a slave in both link 1 and link 2, passively receiving data from the display and control board and WIFI. It then replies with data only after successfully receiving data from the display and control board and WIFI.

[0013] Preferably, the time for one complete data transmission and reception communication process between the display and control board and the frequency converter board in link 1 is Hn, and the time for one complete data transmission and reception communication process between the WIFI module and the frequency converter board in link 2 is Dn, wherein the time Hn is greater than the time Dn.

[0014] Preferably, the frequency converter board and the display and control board communicate periodically according to the timing sequence of link 1, and the WIFI module and the frequency converter board communicate periodically according to the timing sequence of link 2.

[0015] The present invention has the following beneficial effects:

[0016] This invention enables refrigerator network data transmission by setting up an inverter board to forward data from the display and control board and the WIFI module. This compensates for the inability of the display board and the WIFI module to be directly connected, thus forming a new data transmission link and communication control method.

[0017] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] Figure 3 This is a timing diagram showing the communication between the frequency converter board, the display and control board, and the WIFI module. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1:

[0024] Please see Figure 1 As shown, this invention provides a communication control method for a WIFI refrigerator. This method can be implemented by a control system. The model principle of the communication control method for a WIFI refrigerator is as follows: Figure 1 As shown, specifically, the execution flow of the communication control method for this refrigerator includes the following steps:

[0025] Step 1: Power on and initialize the refrigerator;

[0026] Step 2: The frequency converter board receives data from the display and control board and the WIFI module, and the frequency converter board communicates periodically with the display and control board and the WIFI module respectively.

[0027] Specifically, in this embodiment, the implementation process of step two above is as follows:

[0028] like Figure 3 As shown, the communication link between the frequency converter board and the display and control board is link 1, and the communication link between the frequency converter board and the WIFI module is link 2. The time for one complete data transmission and reception communication process between the display and control board and the frequency converter board in link 1 is Hn, and the time for one complete data transmission and reception communication process between the WIFI module and the frequency converter board in link 2 is Dn, where Hn is longer than Dn. The frequency converter board and the display and control board communicate periodically according to the timing sequence of link 1, and the WIFI module and the frequency converter board communicate periodically according to the timing sequence of link 2.

[0029] Step 3: The inverter board receives WIFI data and determines the command type, which includes query commands and setting commands. If the command type is a query command, it jumps to step 2 and communicates according to the normal timing sequence. If the command type is determined to be a setting command, it needs to jump to step 4.

[0030] Step four: After receiving the WIFI module setting command, the frequency converter board forwards it to the display and control board, then receives the data returned by the display and control board and replies with WIFI data.

[0031] Example 2:

[0032] like Figure 2 As shown, this embodiment is a communication system for a WIFI refrigerator, including an inverter board, a WIFI module, and a display and control board. The inverter board is electrically connected to the WIFI module and the display and control board respectively. The WIFI module receives WIFI data transmitted by the control and transmits it to the inverter board, which then forwards it to the display and control board. The display and control board performs queries or settings according to the received instructions, then returns the data to the inverter board, and then uploads it to the terminal device through the WIFI module.

[0033] Therefore, to ensure the stability and integrity of data transmission, the aforementioned frequency converter board passively receives data from the display and control board and WIFI in both Link 1 and Link 2, and only replies with data after successfully receiving data from the display and control board and WIFI.

[0034] Example 3:

[0035] This embodiment describes the control flow of a communication method for a WIFI refrigerator:

[0036] S1, the stage is when the inverter board receives data from the wire control board and the WIFI module after power-on;

[0037] S2, the communication process under the novelty search command, with the communication sequence following... Figure 3 As shown;

[0038] S3: Determine whether the data from the WIFI module is a query or a setting command. If it is a query command, jump directly to S2 and communicate according to the normal timing sequence. If it is determined to be a setting command, jump to S4.

[0039] S4 is the WIFI module setting command. When the WIFI module setting command is received, the WIFI communication rhythm will be interrupted. It is necessary to ensure that the WIFI communication data is stopped before the data is sent to the display and control board and the data is received from the display and control board, and the process returns to S2 until the data is received from the display and control board.

[0040] Repeating steps S2, S3, and S4 will enable the refrigerator to send and receive WIFI communication data normally.
