[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0038] In order to solve the technical problem of timely detecting the specific fault type of the control mainboard when a communication error occurs between the digital display board and the control mainboard due to a fault in the control mainboard, the present application provides a method and device for detecting refrigerator communication faults, which can timely display the specific fault type of the control mainboard.

[0039] Figure 1 A flow chart of a method for detecting a refrigerator communication failure applied to a control mainboard provided in an embodiment of the present application is shown in FIG. Figure 1 , a refrigerator communication failure detection method applied to a control mainboard provided in an embodiment of the present application includes:

[0040] S101: sending first communication data to the digital display board, so that the digital display board returns second communication data to the control main board in response to the first communication data;

[0041] S102: Determine whether a communication failure occurs according to the reception status of the second communication data;

[0042] S103: in case of a communication failure, determining the type of the communication failure;

[0043] S104: Control the digital display board so that the digital display board displays the fault type information corresponding to the fault type.

[0044] Specifically, in the above embodiment, the execution subject is the control main board, and the control main board is connected to the digital display board. Specifically, the transmitting end of the control main board is connected to the receiving end of the digital display board, and the receiving end of the control main board is connected to the transmitting end of the digital display board.

[0045] The control main board sends the first communication data to the digital display board after an interval. If the digital display board receives the first communication data, it returns the second communication data to the control main board in response to the first communication data. The control main board continues to receive the second communication data, and determines whether a communication fault currently occurs according to the reception of the second communication data. If it is determined that a communication fault currently occurs, the control main board determines the fault type of the communication fault according to the reception of the second communication data, and controls the digital display board to display the fault type information corresponding to the fault type.

[0046] In some specific examples of the present application, the interval time can be set to 500 ms, that is, the control main board can be set to send the first communication data to the digital display board once every 500 ms.

[0047] In some specific examples of the present application, the control mainboard sends the first communication data to the digital display board according to the communication format pre-agreed with the digital display board, so that the digital display board performs data verification on the first communication data based on the communication format. The communication format can be pre-stored in the control mainboard and the digital display board in the form of program code.

[0048] In a feasible embodiment of the present application, S102, judging whether a communication failure occurs according to a reception condition of the second communication data, includes:

[0049] Whether a communication failure occurs is determined based on whether the second communication data is received within a continuous preset time; wherein, if the second communication data is not received within a continuous preset time, it is determined that a communication failure occurs.

[0050] Specifically, the control mainboard determines whether a communication failure occurs based on whether the second communication data is received within a continuous preset time. If the control mainboard cannot receive the second communication data returned by the digital display board within a continuous preset time, it means that a communication failure currently occurs; on the contrary, if the control mainboard can receive the second communication data returned by the digital display board within a continuous preset time, it means that no communication failure currently occurs.

[0051] In some specific examples of the present application, the preset time can be freely set by the technician, and usually, the preset time is an integer multiple of the interval time of the control mainboard sending the first communication data. For example, if the interval time is set to 500ms, the preset time can be set to 1min.

[0052] In a feasible embodiment of the present application, S102, judging whether a communication failure occurs according to a reception condition of the second communication data, includes:

[0053] Determine whether a communication failure occurs based on the data type of the second communication data; wherein, when the data type of the second communication data is the first data type, determine that a communication failure occurs, and the second communication data of the first data type is the second communication data generated after the digital display board fails to verify the first communication data; when the data type of the second communication data is the second data type, determine that a communication failure occurs, and the second communication data of the second data type is the second communication data generated when the digital display board fails to receive the first communication data within a continuous preset time.

[0054] Specifically, the digital display board returns the second communication data to the control main board in response to the first communication data. The digital display board will return the second communication data of different data types to the control main board under different reception conditions of the first communication data.

[0055] When the digital display board is able to receive the first communication data, it will perform data verification on the first communication data based on the preset communication format. If the data verification fails, the digital display board returns second communication data with the data type of the first data type to the control main board; when the digital display board cannot receive the first communication data within a continuous preset time, the digital display board returns second communication data with the data type of the second data type to the control main board.

[0056] Based on this, the control mainboard determines whether a communication failure occurs according to the data type of the second communication data. If the data type of the received second communication data is the first data type or the second data type, it indicates that a communication failure currently occurs.

[0057] In a feasible embodiment of the present application, S103, in the case of a communication failure, determining the fault type of the communication failure includes:

[0058] If the second communication data is not received within a continuous preset time, the fault type is determined to be a first fault type; wherein the first fault type is used to describe a receiving end fault of the control mainboard;

[0059] When the data type of the second communication data is the first data type, determining the fault type is the second fault type; wherein the second fault type is used to describe the existence of communication interference between the control main board and the digital display board;

[0060] When the data type of the second communication data is the second data type, the fault type is determined to be a third fault type; wherein the third fault type is used to describe a sending end fault of the control mainboard.

[0061] Specifically, if the second communication data is not received within a continuous preset time, it means that the receiving end of the control mainboard cannot receive normally, and the fault type is determined to be the first fault type, that is, it is determined that the receiving end of the control mainboard is faulty.

[0062] When the data type of the second communication data is the first data type, it means that the digital display board can receive the first communication data, but the data verification of the first communication data fails. Since the digital display board will verify the first communication data based on the preset communication format, if the digital display board fails to verify the data of the first communication data, it means that the first communication data has changed during the transmission process, and noise that does not conform to the communication format has been added. Therefore, when the data type of the second communication data received by the control main board is the first data type, it means that there is communication interference between the control main board and the digital display board, and the fault type is determined to be the second fault type, that is, it is determined that there is communication interference between the control main board and the digital display board.

[0063] When the data type of the second communication data is the second data type, it means that the digital display board cannot receive the first communication data within the continuous preset time, which means that the sending end of the control main board cannot send normally, and the fault type is determined to be the third fault type, that is, the sending end of the control main board is faulty.

[0064] In a feasible embodiment of the present application, S104, controlling the digital display board includes:

[0065] When it is determined that the fault type is the first fault type, the first fault type information is sent to the digital display board so that the digital display board displays the first fault type information; wherein the first fault type information is used to describe that the fault type is the first fault type.

[0066] Specifically, when the fault type is determined to be the first fault type, the receiving end of the control mainboard cannot normally receive the second communication data, but the sending end of the control mainboard is normal. The control mainboard sends the first fault type information to the digital display board through the sending end of the control mainboard, so that the digital display board displays the first fault type information.

[0067] In some specific examples of the present application, the digital display board can be specifically displayed through a double eight display screen. When the digital display board receives the first fault type information, the double eight display screen of the digital display board displays the character "Er".

[0068] Through the technical solution provided by the present application, when a communication failure occurs between the control main board and the digital display board, after-sales personnel can quickly identify the specific type of fault on the control main board that caused the communication error, and thus promptly handle the specific fault type of the control main board.

[0069] Figure 2A flowchart of a method for detecting refrigerator communication failures applied to a digital display board provided in an embodiment of the present application is provided. Figure 2 , a refrigerator communication failure detection method applied to a digital display board provided in an embodiment of the present application includes:

[0070] S201: judging whether a communication failure occurs according to a reception condition of first communication data; wherein the first communication data is communication data sent by the control mainboard;

[0071] S202: in case of a communication failure, determining the type of the communication failure;

[0072] S203: Displaying fault type information corresponding to the fault type; or,

[0073] S204: Based on the control of the control mainboard, display the fault type information corresponding to the fault type.

[0074] Specifically, in the above embodiment, the execution body is a digital display board, which is interconnected with the control main board. Specifically, the sending end of the digital display board is connected to the receiving end of the control main board, and the receiving end of the digital display board is connected to the sending end of the control main board.

[0075] The digital display board continuously receives the first communication data sent by the control main board. Under normal circumstances, the control main board sends the first communication data to the digital display board once after an interval, and the digital display board also receives the first communication data after an interval. The digital display board continuously receives the first communication data, and determines whether a communication fault currently occurs according to the reception of the first communication data. If it is determined that a communication fault currently occurs, the digital display board determines the fault type of the communication fault according to the reception of the first communication data, and displays the fault type information corresponding to the fault type.

[0076] In a feasible embodiment of the present application, S201, judging whether a communication failure occurs according to a reception condition of the first communication data, includes:

[0077] Determining whether a communication failure occurs according to whether the first communication data is received within a continuous preset time; wherein, if the first communication data is not received within a continuous preset time, it is determined that a communication failure occurs;

[0078] Specifically, the digital display board determines whether a communication failure occurs according to the reception of the first communication data. If the digital display board does not receive the first communication data within a continuous preset time, it means that a communication failure currently occurs; on the contrary, if the digital display board can receive the first communication data within a continuous preset time, it means that a communication failure currently occurs.

[0079] In a feasible embodiment of the present application, S201, judging whether a communication failure occurs according to a reception condition of the first communication data, further includes:

[0080] Whether a communication failure occurs is determined based on whether the data verification of the first communication data is successful; wherein, if the verification of the first communication data fails, it is determined that a communication failure occurs.

[0081] Specifically, the digital display board determines whether a communication failure occurs based on the reception of the first communication data. After receiving the first communication data, the digital display board will perform data verification on the first communication data according to the preset communication format to verify whether the currently received first communication data conforms to the communication format. If the currently received first communication data conforms to the communication format, the verification of the first communication data succeeds; if the currently received first communication data does not conform to the communication format, the verification of the first communication data fails.

[0082] If the verification of the first communication data fails, it means that the currently received first communication data does not conform to the communication format, which means that the first communication data has changed during the transmission process and noise that does not conform to the communication format has been added. The digital display board can determine that a communication failure has occurred if the verification of the first communication data fails.

[0083] In a feasible embodiment of the present application, S202, when a communication failure occurs, determining the fault type of the communication failure includes:

[0084] When the first communication data is not received within a continuous preset time, second communication data of a second data type is sent to the control mainboard; wherein the second communication data of the second data type is used to configure the initialization of the sending end and the receiving end of the control mainboard;

[0085] Initialize the sending end and the receiving end of the digital display board and receive the first communication data again;

[0086] When the first communication data is not received within a continuous preset time, the fault type is determined to be a third fault type; wherein the third fault type is used to describe a sending end fault of the control mainboard.

[0087] Specifically, to further clarify that the current communication failure is caused by a failure of the transmitting end of the control mainboard, in this embodiment, when the digital display board does not receive the first communication data within a continuous preset time, it generates second communication data of a second data type, and sends the second communication data of the second data type to the control mainboard through the transmitting end of the digital display board, so that the control mainboard reconfigures the transmitting end and the receiving end of the control mainboard in response to the second communication data. At the same time, the digital display board also reconfigures its own transmitting end and receiving end.

[0088] If the control mainboard successfully receives the second communication data of the second data type, the first communication data is sent to the digital display board again. If the digital display board still fails to receive the first communication data within a continuous preset time, it is determined that the sending end of the control mainboard is faulty; if the digital display board can receive the first communication data within a continuous preset time, it is determined that the sending end of the control mainboard has returned to normal.

[0089] In a feasible embodiment of the present application, the second communication data of the second data type can also be configured so that the control mainboard is sent through the receiving end of the control mainboard and received through the sending end of the control mainboard. At this time, after the digital display board generates the second communication data of the second data type, it is also configured to be sent through the receiving end of the digital display board and received through the sending end of the digital display board.

[0090] In this embodiment, after receiving the second communication data whose data type is the second data type, the control main board sends third fault type information to the digital display board through the receiving end of the control main board. The third fault type information is used for the third fault type, that is, notifying the digital display board that the sending end of the current control main board is faulty.

[0091] If the digital display board can receive the third fault type information, the fault type is determined to be the third fault type; if the digital display board cannot receive the third fault type information, the fault type is determined to be the fourth fault type. The fourth fault type is used to describe a fault at the sending end of the control main board and damage to the communication line between the control main board and the digital display board.

[0092] In a feasible embodiment of the present application, S202, when a communication failure occurs, determining the fault type of the communication failure further includes:

[0093] In the case where the verification of the first communication data fails, second communication data whose data type is the first data type is sent to the control mainboard; wherein the second communication data whose data type is the first data type is used to configure the control mainboard to add noise filtering;

[0094] Configure the digital display board to add noise filtering and re-receive the first communication data;

[0095] In the case where the verification of the first communication data still fails, the fault type is determined to be the second fault type; wherein the second fault type is used to describe the communication interference between the control main board and the digital display board.

[0096] Specifically, in order to further clarify that the current communication failure is caused by the communication interference between the control mainboard and the digital display board, in this embodiment, when the digital display board fails to verify the first communication data, second communication data with a data type of the first data type is generated, and the second communication data with a data type of the first data type is sent to the control mainboard through the sending end of the digital display board, so that the control mainboard adds noise filtering in response to the second communication data. At the same time, the digital display board is configured to add noise filtering itself.

[0097] After noise filtering is added to both the control mainboard and the digital display board, the control mainboard sends the first communication data to the digital display board again after noise filtering, and the digital display board receives the first communication data after noise filtering, and performs data verification on the first communication data after noise filtering. In the case where the digital display board still fails to verify the first communication data after noise filtering, it is determined that the fault type is the second fault type; in the case where the digital display board successfully verifies the first communication data after noise filtering, it is determined that the communication interference between the digital display board and the control mainboard is restored.

[0098] When the fault type of the communication fault between the control mainboard and the digital display board is the second fault type (i.e., communication interference between the control mainboard and the digital display board) or the third fault type (i.e., a fault at the control mainboard transmitter), the digital display board cannot receive fault type information from the control mainboard. In order to enable the digital display board to display the communication faults of the second fault type and the third fault type in a timely manner, in a feasible embodiment of the present application, the fault type information corresponding to the fault type is displayed, including:

[0099] In the case where it is determined that the fault type is the second fault type, the second fault type information is displayed; wherein the second fault type information is used to describe that the fault type is the second fault type;

[0100] In the case where it is determined that the fault type is the third fault type, the third fault type information is displayed; wherein the third fault type information is used to describe that the fault type is the third fault type.

[0101] Specifically, when the digital display board determines that the fault type is the second fault type, there is communication interference between the digital display board and the control main board. At this time, the digital display board automatically displays the second fault type information. In some specific examples of the present application, the digital display board can be displayed through a double eight display screen. When the digital display board receives the second fault type information, the double eight display screen of the digital display board displays the character "Eg".

[0102] When the digital display board determines that the fault type is the third fault type, the digital display board cannot receive data from the control main board. At this time, the digital display board displays the third fault type information by itself. In some specific examples of the present application, when the digital display board receives the third fault type information, the double eight display screen of the digital display board displays the character "Ed".

[0103] Based on the above implementations, in the technical solution provided by the present application, data is continuously exchanged between the control mainboard and the digital display board, the fault type of the control mainboard is determined based on the interactive status of the data interaction, and the fault type information corresponding to the fault type is displayed on the digital display board in a timely manner. Therefore, when a communication failure occurs between the control mainboard and the digital display board, after-sales personnel can know in a timely manner what kind of fault of the control mainboard is caused, which is convenient for after-sales service of the refrigerator.
