[0083] Please see the attached Figure 1 , Figure 1 This is a flow chart of the main steps of the air conditioner mainboard testing method according to an embodiment of the present application. Figure 1 As shown, the air conditioner motherboard testing method of this application mainly includes steps S1 to S3:

[0084] Step S1, determining the type of the motherboard to be tested;

[0085] In this embodiment, the main board to be tested is generally an external board or an internal board of an air conditioner. In an air conditioning system, it is usually divided into an external unit and an internal unit. Among them, the external board generally refers to the main control board installed outside the air conditioner, which is responsible for controlling the cooling cycle and other external functions of the air conditioner, while the internal board is installed inside the air conditioner, which is responsible for controlling internal functions such as temperature and wind speed.

[0086] Step S2: Based on the judgment result, selectively using the second control center to transmit the test signal generated by the first control center to the motherboard to be tested;

[0087] In this embodiment, the judgment result is divided into external or internal boards. This judgment result is only for the mainboard under test. In actual scenarios, if both an external board and an internal board are tested simultaneously, a judgment is performed for each mainboard under test. The judgment results of the two control centers do not affect each other's subsequent related operations. The first control center and the second control center are generally main control microcontroller units (MCUs), which integrate functions such as a central processing unit, memory, input and output interfaces, timers / counters, and communication interfaces. Signal transmission methods include but are not limited to direct transmission, bridge transmission, relay transmission, and distributed transmission.

[0088] In one embodiment, signal transmission methods include direct transmission and bridge transmission. Direct transmission refers to direct communication between the motherboard under test and the first control center, while bridge transmission refers to communication between the motherboard under test and the first control center via a second control center. In this embodiment, if the motherboard under test is an external board, direct transmission is selected; if the motherboard under test is an internal board, bridge transmission is selected. Because in actual testing scenarios, air conditioner external boards typically serve as the primary data transmitter, while internal boards typically serve as the primary data receiver, corresponding signal transmission methods are selected based on these two types of motherboards under test to achieve signal transmission between the motherboard under test and the first control center. Specifically, if the motherboard under test is an internal board, a module of the same type as the first control center can be used as a communication bridge to reduce testing costs. Through the bridge method, the internal board, which typically serves as the primary data receiver, can smoothly connect to the first control center and share the same first control center with the external board, which typically serves as the primary data transmitter. This simplifies the testing process, reduces testing costs, and improves testing efficiency.

[0089] In another embodiment, the test records for the motherboard to be tested are also transmitted to the first control center, which may specifically include: if the type of the motherboard to be tested is an external board, then based on the direct transmission signal transmission method, the test records for the motherboard to be tested are transmitted to the first control center; if the type of the motherboard to be tested is an internal board, then based on the bridge transmission signal transmission method, the test records for the motherboard to be tested are transmitted to the first control center. The test records may include all data parameters generated during the test process, such as the number of each type of test, the number of communications between the motherboard to be tested and the first control center, the test duration, etc. Transmitting the test records to the first control center can provide data support for the first control center to analyze the execution of the test tasks, and can also generate test reports based on these test records.

[0090] Step S3: testing the motherboard to be tested based on the test signal;

[0091] In this embodiment, the tests performed on the motherboard to be tested include but are not limited to reset action confirmation, power switch impact test, communication test, controller load capacity confirmation test, etc.

[0092] Based on the above steps S1 to S3, it can be seen that in implementing the technical solution of the present application, before testing the motherboard to be tested, the type of the motherboard to be tested is first determined, and then the corresponding signal transmission method is selected according to the type of the motherboard to be tested. Through the present application, the same type or the same test equipment can be used for different types of motherboards to be tested, thereby reducing testing costs and improving testing efficiency.

[0093] In one embodiment, Figure 1 The air conditioner motherboard testing method of the present application may further include: obtaining real-time test results for the motherboard under test; and displaying the real-time test results on a display screen. In this embodiment, the test results are displayed on the display screen, allowing operators to monitor and analyze the test process and results in real time. The test results can be transmitted to the display screen directly or indirectly via wired or wireless means, without limitation.

[0094] In one embodiment, Figure 1 The air conditioner motherboard testing method of the present application may further include: obtaining real-time test results for the motherboard under test; and uploading the real-time test results to a cloud server. In this embodiment, the upload to the cloud server can be done directly or indirectly via a wired or wireless method. Furthermore, the cloud server can store the test results and, based on pre-set instructions, transmit the results to an operator's terminal device, thereby providing real-time notification of the operator's current test status.

[0095] exist Figure 1 Based on the embodiment shown, please refer to the attached Figure 2 , Figure 2 This is a flow chart of the main steps of testing a motherboard to be tested according to an embodiment of the present application. Figure 2 As shown, step S3 may further include steps S31 to S34:

[0096] Step S31: Based on the test signal, control the motherboard to be tested to perform power-on or power-off actions;

[0097] In this embodiment, based on the test signal, the power on or off of the mainboard to be tested is controlled by switching components such as relays.

[0098] Step S32: If the mainboard under test performs a power-on action, after the mainboard under test is powered on successfully, the mainboard under test is controlled to communicate with the first control center through a corresponding signal transmission method;

[0099] In this embodiment, the mainboard to be tested is powered on successfully, that is, the mainboard to be tested is connected to a power source and started, and when the mainboard to be tested is powered on successfully, communication is established with the first control center immediately.

[0100] Step S33: obtaining the number of times the motherboard under test is powered on and off, and obtaining the content of the communication between the motherboard under test and the first control center;

[0101] In this embodiment, the content of the communication may include specific communication frames or commands, device signals, firmware versions, hardware configurations, working conditions of various components, communication times, etc.

[0102] Step S34: Generate a test record based on the number of power-on and power-off times and the content of the communication.

[0103] In this embodiment, the generated test record can be a time-line test event record or a summary test report, which includes all data parameters or specific data parameters during the test of the motherboard to be tested.

[0104] In one embodiment, the communication protocols between the motherboard under test and the first and second control centers include at least Humbus, RS485, UART, and PQ. Signal transmission between the first and second control centers can be performed via a pre-defined proprietary communication method. This embodiment supports commonly used protocol types, thus meeting the vast majority of test scenarios and improving test efficiency.

[0105] Please see the attached Figure 3 , Figure 3 FIG. 1 is a schematic diagram of an implementation example of an air conditioner mainboard testing method according to an embodiment of the present application. Figure 3As shown, the first master MCU serves as the first control center, and the second master MCU serves as the second control center. When the main board under test is an external board, the external board communicates directly with the first master MCU, and the external board directly establishes communication with the first master and sends the communication count to the first master MCU. When the main board under test is an internal board, the internal board and the first master MCU establish a bridged signal transmission method using the second master MCU as a communication bridge, thereby indirectly sending the communication count to the first master MCU. The communication protocol between the external board and the first master MCU supports at least Humbus, RS485, UART, and PQ, and the communication protocol between the internal board and the second master MCU supports at least Humbus, RS485, UART, and PQ. Serial communication, parallel communication, CAN bus, etc. can be used between the first and second master MCUs.
