Technical Field

[0001] This application relates to the field of electrical technology, specifically to a method, device, refrigerator, and computer-readable storage medium for detecting the status of a damper. Background Technology

[0002] After prolonged use, ice buildup inside the refrigerator's air damper can cause it to slam shut or become impossible to open, affecting cooling efficiency and potentially leading to spoilage of refrigerated items. Current technology typically uses touch-sensitive sensors to detect damper malfunctions. If the sensor detects a point where the damper is still closed when ventilation is needed, a malfunction is identified. However, if the sensor malfunctions, it cannot accurately determine if the damper is faulty. Therefore, a more effective method for accurately detecting refrigerator damper malfunctions is needed.

[0022] Determine the matching relationship between the actual damper opening angle and the theoretical damper opening angle corresponding to the opening and closing state of the target damper;

[0023] If the matching relationship indicates that the actual damper opening angle does not match the theoretical damper opening angle, the working state of the target damper is determined to be an abnormal working state.

[0024] If the matching relationship indicates that the actual damper opening angle matches the theoretical damper opening angle, the working state of the target damper is determined to be the normal working state.

[0025] In some embodiments of this application, after determining the working state of the target damper based on the target image, the method further includes:

[0026] If the target damper is in an abnormal working state, the target alarm device will issue an alarm.

It should be understood that those skilled in the art will recognize that this application can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0062] This application provides a method, apparatus, refrigerator, and computer-readable storage medium for detecting the status of a damper, which are described in detail below.

[0063] Please see Figure 1 , Figure 1This is a schematic diagram of a damper status detection system provided in an embodiment of this application. The damper status detection system may include a cooling device 100 and a storage device 200. The storage device 200 can store image data of the damper received by the corresponding image sensor and can transmit the image data to the cooling device 100. Figure 1 The refrigeration device 100 in the storage device 200 can obtain the control program and image data corresponding to the damper status detection method stored in the storage device 200 to execute the damper status detection method in this application.

[0064] In this embodiment of the application, the refrigeration equipment 100 may include, but is not limited to, refrigerators, air conditioners, etc.

[0065] In this embodiment of the application, the storage device 200 may include, but is not limited to, mobile storage devices, cloud storage devices, local storage devices, etc.

[0066] In the embodiments of this application, the cooling device 100 and the storage device 200 can communicate through any communication method, including but not limited to mobile communication based on the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), and Worldwide Interoperability for Microwave Access (WiMAX), or computer network communication based on the TCP / IP Protocol Suite (TCP / IP) and User Datagram Protocol (UDP).

[0067] It should be noted that, Figure 1 The schematic diagram of the damper status detection system shown is merely an example. The damper status detection system and scenario described in this application are for the purpose of more clearly illustrating the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of damper status detection systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0068] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the damper status detection method in this application. The method includes the following steps 201-203:

[0069] 201. Determine the working environment of the target damper.

[0070] In this embodiment, the target damper can refer to the damper in the refrigerator, which is located above the air supply duct between the food storage compartment and the compressor, and is used to control the air volume delivered to the food storage compartment. When the damper is open, the cold air compressed by the compressor can enter the food storage compartment through the damper after the fan rotates. When the damper is closed, the cold air cannot enter the food storage compartment.

[0071] However, in reality, the refrigerator's damper often malfunctions and fails to open or close compared to dampers in other scenarios because the ambient temperature is too low, leading to icing. Therefore, in this embodiment, if the humidity in the ambient air surrounding the target damper is high, coupled with a low ambient temperature, the target damper is prone to frost or ice formation. Ice formation is more likely when the humidity in the target damper's working environment is high. Therefore, the humidity in the target damper's working environment can be detected.

[0072] 202. If the target damper is in the target working environment, acquire the target image of the target damper.

[0073] Therefore, when the humidity of the working environment of the target damper is too high, it can be determined that the target damper is in the target working environment. At this time, a preset image sensor can be started to acquire the target image of the damper. In this embodiment, a humidity sensor can be installed at an appropriate location to obtain the humidity of the target damper. Then, when the ambient humidity of the target damper is less than a predetermined humidity threshold, it can be determined that the target damper is in the target working environment.

[0074] 203. Determine the working status of the target damper based on the target image.

[0075] Once the target image is acquired, the operating status of the target damper can be detected using a preset image detection model. For example, if image detection determines that the target damper is open, but the current control command inside the refrigerator requires the damper to close, then the operating status of the target damper is determined to be abnormal. Alternatively, if the target damper is detected to be closed, but the current control command inside the refrigerator requires the damper to open, then the operating status of the target damper is also determined to be abnormal. Otherwise, if image detection determines that the damper's open / closed state matches the control command, then the target damper is determined to be in a normal operating state.

[0076] Alternatively, in this embodiment, it is possible to detect whether the damper is frosted or icy. When the damper is frosted or icy, the ice or frost will affect the opening and closing angle of the damper, and may even jam the damper. Therefore, when there is frost or ice on the damper, the probability of the damper operating abnormally is extremely high. Thus, if the damper is frosted or icy, it can be determined that the damper's operating state is abnormal; while if the damper is not frosted or icy, it can be determined that the damper's operating state is normal.

[0077] It should be noted that, in the embodiments of this application, the image detection model can be any type of image detection model that has been trained, and the specific embodiments of this application are not limited. For example, when the image detection model needs to detect whether the damper is iced or frosted, during the training phase, a large number of damper images with added icing or frost can be fed into the image detection model for training, so as to help the image detection model recognize the features of frost or ice on the damper, so that in the subsequent model application phase, the image detection model can detect whether the damper is iced or frosted based on the target image acquired in real time.

[0078] To better implement the embodiments of this application, in one embodiment of this application, the working environment of the target damper is determined, including:

[0079] Obtain the operating ambient temperature of the target damper; determine the operating environment of the target damper based on the operating ambient temperature.

[0080] The above embodiments provide a scheme for determining the working environment of a damper by determining the humidity of its operating environment. However, under normal circumstances, the original humidity in the air, combined with the cold air from the compressor, easily causes the damper to frost or ice over. Only in some very dry areas will the damper not freeze. Therefore, it can be seen that the common condition for both is low temperature. In this case, the working environment of the damper can be determined by detecting temperature, rather than humidity. Based on this, in this embodiment, a temperature sensor can be installed in an appropriate location to obtain the working environment temperature of the target damper. When the working environment temperature of the target damper is lower than a set temperature threshold, it can be determined that the target damper is in the target working environment; when the working environment temperature of the target damper is greater than or equal to the temperature threshold, it can be determined that the target damper is not in the target working environment.

[0081] When the working environment of the target damper can be determined based on temperature, subsequent judgments based on humidity are unnecessary. Furthermore, once the target damper is determined to be in its target working environment based on the ambient temperature, the target image of the target damper can then be acquired.

[0082] To better implement the embodiments of this application, in one embodiment, determining the working state of the target damper based on the target image includes:

[0083] Analyze the target image to determine the angle opening and closing characteristics and shape characteristics of the target damper; based on the angle opening and closing characteristics and shape characteristics, determine the working state of the target damper.

[0084] The above embodiments provide a scheme for detecting whether a damper is iced or frosted using an image detection model. However, in practice, other unexpected situations may prevent the damper from closing properly, such as damage to the damper's transmission mechanism, causing the damper to be unable to open and close normally. Therefore, in this embodiment, after acquiring the target image, the opening and closing angle of the target damper can be analyzed, and then combined with the frosting or icing features on the damper, the working state of the damper can be determined. When the opening angle of the damper indicates that the damper is closed, and the shape of the damper indicates that the damper is frosted or iced, and the current control command of the refrigerator to the damper requires the damper to be open, then the working state of the target damper can be determined to be abnormal. Alternatively, when the opening angle of the damper indicates that the damper is open, and the current control command of the refrigerator to the damper requires the damper to be closed, and the damper is also frosted or iced, then the working state of the target damper can be determined to be abnormal. Otherwise, when there is no frosting or icing on the damper and the opening angle of the damper matches the opening angle corresponding to the control command, then the working state of the damper can be determined to be normal.

[0085] It should be noted that, in this embodiment of the application, training sample images of each opening and closing angle of the damper can be sent to the image detection model to train the image detection model, so that the image detection model can identify each opening and closing angle of the damper, including the angle when closed and the angle when fully open, on the basis of recognizing ice or frost.

[0086] To better implement the embodiments of this application, in one embodiment, the working state of the target damper is determined based on the angle opening and closing characteristics and shape characteristics, including:

[0087] Based on the angle of opening and closing characteristics, determine the opening and closing state of the target damper; based on the shape characteristics, determine the icing state of the target damper; based on the opening and closing state and the icing state, determine the working state of the target damper.

[0088] The above embodiments provide a scheme for determining the working state of the damper based on its opening and closing angle and shape characteristics. However, in reality, even after the damper freezes, it still retains its normal opening and closing function; only the probability of it failing to open and close properly increases. In this case, the damper can still function normally. Based on this, and considering both the damper's opening and closing state and its freezing state, if the damper is frozen or frosted, but its opening and closing angle matches the opening and closing angle corresponding to the control command, it can be determined as a suspected abnormal working state. In this case, defrosting or de-icing operations can be performed on the damper.

[0089] To better implement the embodiments of this application, in one embodiment, the working state of the target damper is determined based on the switching state and the icing state, including:

[0090] If the target damper is in a target icing state, obtain the theoretical damper opening and closing angle corresponding to the current control command; determine the matching relationship between the actual damper opening and closing angle and the theoretical damper opening and closing angle corresponding to the opening and closing state of the target damper; if the matching relationship indicates that the actual damper opening and closing angle and the theoretical damper opening and closing angle do not match, determine that the working state of the target damper is an abnormal working state; if the matching relationship indicates that the actual damper opening and closing angle and the theoretical damper opening and closing angle match, determine that the working state of the target damper is a normal working state.

[0091] The above embodiments provide a scheme for determining the working state of a damper by combining its shape features or opening / closing angle features. However, in reality, the probability of damage to the damper's transmission device is low; the damper usually fails to open or close properly only when it is iced or frosted. Therefore, in this embodiment, the opening / closing angle features of the damper can be analyzed after determining whether it is iced or frosted. This method of feature analysis reduces the amount of data required for feature analysis of certain target images, thereby reducing the waste of computational resources.

[0092] Therefore, the angular characteristics of the damper only need to be considered when the damper is in an icy or frosty state. Thus, when the matching relationship indicates that the actual damper opening angle does not match the theoretical damper opening angle, the target damper is determined to be in an abnormal operating state; or, when the matching relationship indicates that the actual damper opening angle matches the theoretical damper opening angle, the target damper is determined to be in a normal operating state.

[0093] To better implement the embodiments of this application, in one embodiment, after determining the working state of the target damper based on the target image, the method further includes:

[0094] If the target damper is in an abnormal working state, the target alarm device will issue an alarm.

[0095] In this embodiment, the target alarm device can be a terminal device that communicates with the refrigerator equipped with the target air damper, such as a mobile phone or tablet. When the air damper malfunctions, an alarm can be triggered to the user via the corresponding application on the mobile phone or tablet. Alternatively, the target alarm device in this embodiment can be a buzzer built into the refrigerator itself, which sounds an alarm when the air damper is in an abnormal working state. Alternatively, the target alarm device can be a display panel on the refrigerator, which displays the message "Air damper malfunction" when the air damper is in an abnormal working state, thus achieving the purpose of alarm. Alternatively, there can be multiple target alarm devices, such as terminal devices, display panels, buzzers, etc., and this embodiment does not limit the specific implementation.

[0096] To better implement the damper status detection method in the embodiments of this application, the embodiments of this application also provide a damper status detection device, such as... Figure 3 As shown, the device 300 includes:

[0097] The first determining module 301 is used to determine the working environment of the target damper;

[0098] The acquisition module 302 is used to acquire the target image of the target damper if the target damper is in the target working environment;

[0099] The second determining module 303 is used to determine the working status of the target damper based on the target image.

[0100] The damper status detection device provided in this application first determines the working environment of the target damper through the first determining module 301. If the working environment of the target damper is in an abnormal working environment, the acquiring module 302 begins to acquire the target image of the target damper, so that the second determining module 303 can detect the working status of the target damper. This avoids the need for a long-term, computationally-intensive image detection process and saves computational resources when performing image detection on the target damper. At the same time, it can also determine the opening and closing status of the damper through image detection technology, providing an additional damper status detection method.

[0101] In some embodiments of this application, the first determining module 301 is specifically used for:

[0107] Analyze the target image to determine the angle opening and closing characteristics and shape characteristics of the target damper;

[0109] In some embodiments of this application, the second determining module 303 is further configured to:

[0110] Based on the angle of opening and closing, determine the opening and closing status of the target damper;

[0111] Determine the icing state of the target damper based on its shape characteristics;

[0112] Determine the operating status of the target damper based on its on / off status and icing status.

[0113] In some embodiments of this application, the second determining module 303 is further configured to:

[0114] If the target damper is in a state of ice formation, obtain the theoretical damper opening and closing angle corresponding to the current control command;

[0115] Determine the matching relationship between the actual damper opening angle and the theoretical damper opening angle corresponding to the opening and closing state of the target damper;

[0116] If the matching relationship indicates that the actual damper opening angle does not match the theoretical damper opening angle, the working state of the target damper is determined to be an abnormal working state.

[0117] If the matching relationship indicates that the actual damper opening angle matches the theoretical damper opening angle, then the working state of the target damper is determined to be the normal working state.

[0118] In some embodiments of this application, the damper status detection device further includes an alarm module, which is specifically used for:

[0119] If the target damper is in an abnormal working state, the target alarm device will issue an alarm.

[0120] This application also provides a refrigerator, which includes a processor, a radiator, a damper status detector, a fan, a memory, and a computer program stored in the memory and executable on the processor. The processor executes the computer program to implement the steps of the damper status detection method according to any one of the embodiments of this application.
