Description

Technical Field

[0001] This application relates to the field of home appliance technology, specifically to a control method for refrigeration equipment, a refrigeration control system, and a readable storage medium. Background Technology

[0002] With the development of refrigeration equipment, taking refrigerators as an example, a demonstration mode has evolved to address the needs of refrigerators sold in stores. This mode is primarily due to safety considerations in stores. Because stores restrict electricity use at sales points, refrigerators often cannot be started and used normally. Therefore, a demonstration mode was introduced, in which the refrigerator's compressor does not start, thus meeting the store's requirements while ensuring the refrigerator can be displayed as effectively as possible.

[0003] However, in existing technology, refrigerators require a complex combination of buttons to activate the demonstration mode. The reason for designing the demonstration mode activation method with a complex button combination is to prevent accidental activation by users in the home, which could cause the refrigerator to malfunction. This method of switching demonstration modes is cumbersome and lacks precision. Summary of the Invention

[0004] To address the aforementioned problems, this application proposes a control method for a refrigeration device, a refrigeration control system, and a readable storage medium, aiming to resolve these issues.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a control method for a refrigeration device, the control method comprising: the refrigeration device uploading internal sensing data to the cloud; the cloud determining external environmental information of the refrigeration device based on the internal sensing data and transmitting it back to the refrigeration device; the refrigeration device operating in demonstration mode or non-demonstration mode based on the external environmental information.

[0006] The steps for the refrigeration equipment to operate in demonstration mode or non-demonstration mode based on external environmental information include: if the external environmental information indicates that the equipment is inside the store, the refrigeration equipment operates in demonstration mode; if the external environmental information indicates that the equipment is outside the store, the refrigeration equipment operates in non-demonstration mode.

[0007] The refrigeration equipment includes a temperature sensor or an infrared sensor. The steps for the refrigeration equipment to upload internal sensing data to the cloud include: the refrigeration equipment periodically acquiring the temperature data sequence of the refrigeration chamber using the temperature sensor or infrared sensor, and sending the temperature data sequence to the cloud.

[0008] The steps for determining the external environment information of the refrigeration equipment based on internal sensor data include: the cloud performs calculations based on the temperature data sequence to obtain the temperature fluctuation amplitude of the temperature data sequence; if the temperature fluctuation amplitude is less than a preset fluctuation threshold, the cloud determines that the refrigeration equipment corresponding to the temperature data sequence is inside the store; if the temperature fluctuation amplitude is greater than or equal to the preset fluctuation threshold, the cloud determines that the refrigeration equipment corresponding to the temperature data sequence is outside the store.

[0009] The steps involved in cloud-based calculations to obtain the temperature fluctuation amplitude of the temperature data sequence include: smoothing the temperature data sequence in the cloud to obtain a smoothed temperature data sequence; obtaining the maximum and minimum values ​​in the smoothed temperature data sequence; and calculating the temperature fluctuation amplitude based on the maximum and minimum values.

[0010] The refrigeration equipment includes a weight sensor. The steps for the refrigeration equipment to upload internal sensing data to the cloud include: the refrigeration equipment periodically uses the weight sensor to acquire weight sensing data of the refrigeration chamber and sends the weight sensing data to the cloud; the steps for the cloud to determine the external environmental information of the refrigeration equipment based on the internal sensing data include: the cloud compares the weight sensing data with a preset weight threshold; if the weight sensing data is less than the preset weight threshold, the cloud determines that the refrigeration equipment corresponding to the weight sensing data is inside the store; if the weight sensing data is greater than or equal to the preset weight threshold, the cloud determines that the refrigeration equipment corresponding to the weight sensing data is outside the store.

[0011] The refrigeration equipment includes a vision sensor. The steps for the refrigeration equipment to upload internal sensing data to the cloud include: the refrigeration equipment periodically uses the vision sensor to acquire image data of the refrigeration chamber of the refrigeration equipment and sends the image data to the cloud; the steps for the cloud to determine the external environment information of the refrigeration equipment based on the internal sensing data include: the cloud performs image recognition and analysis on the image data to determine whether the corresponding refrigeration equipment is in the store.

[0012] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a refrigeration control system, which includes a cloud and multiple refrigeration devices. The cloud is communicatively connected to the multiple refrigeration devices, and each refrigeration device uploads its internal sensing data to the cloud. The cloud determines the external environment information of the refrigeration device based on the internal sensing data and sends it back to the refrigeration device. The refrigeration device operates in demonstration mode or non-demonstration mode based on the external environment information.

[0013] The refrigeration equipment includes a controller and refrigeration components, sensing components, and a communication module connected to the controller. The controller controls the sensing components to acquire internal sensing data from the refrigeration equipment. The controller transmits this internal sensing data to the cloud via the communication module and receives external environmental information from the cloud via the communication module. Based on the external environmental information, the controller controls the refrigeration equipment to operate in either a demonstration mode or a non-demonstration mode. The sensing components include any one or a combination of temperature sensors, infrared sensors, weight sensors, or vision sensors.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a readable storage medium that stores program instructions internally, which are executed by a processor to implement the control method of the refrigeration device described above.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, the control method for the refrigeration equipment in this application includes: the refrigeration equipment uploading internal sensor data to the cloud; the cloud determining the external environmental information of the refrigeration equipment based on the internal sensor data and transmitting it back to the refrigeration equipment; and the refrigeration equipment operating in demonstration mode or non-demonstration mode based on the external environmental information. Through this method, this application can remotely control the refrigeration equipment to operate in demonstration mode or non-demonstration mode via the cloud, thereby reducing the difficulty of switching the refrigeration equipment's demonstration mode; furthermore, the cloud determining the external environmental information of the refrigeration equipment based on its internal sensor data can improve the accuracy of the refrigeration equipment's demonstration mode switching.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] With the development of refrigeration equipment, taking refrigerators as an example, a demonstration mode has evolved to address the needs of refrigerators sold in stores. This mode is primarily due to safety considerations in stores. Because stores restrict electricity use at sales points, refrigerators often cannot be started and used normally. Therefore, a demonstration mode was introduced, in which the refrigerator's compressor does not start, thus meeting the store's requirements while ensuring the refrigerator can be displayed as effectively as possible.

[0028] However, in existing technology, refrigerators require a complex combination of buttons to activate the demonstration mode. The reason for designing the demonstration mode activation method with a complex button combination is to prevent accidental activation by users in the home, which could cause the refrigerator to malfunction. This method of switching demonstration modes is cumbersome and lacks precision.

[0029] Before introducing the control method of the refrigeration equipment of this application, it is necessary to first introduce the structure of the refrigeration equipment. The refrigeration equipment in this embodiment includes refrigeration components, sensing components, controllers, and communication modules. These parts work together to ensure that the internal environment of the refrigeration equipment maintains a constant low temperature.

[0030] The refrigeration assembly is the core of a refrigeration system, responsible for generating cold air and controlling the internal temperature. A typical refrigeration assembly consists of components such as a compressor, condenser, expansion valve, and evaporator. The compressor increases the pressure and temperature of the refrigerant gas by compressing it, thus propelling the refrigerant through the system. The condenser cools the high-temperature gas discharged from the compressor into a liquid state, while the expansion valve reduces the pressure of the high-pressure liquid refrigerant to a low-pressure gaseous state, allowing it to absorb heat in the evaporator. The evaporator, located in the refrigeration chamber of the refrigeration system, is the heat-absorbing component, lowering the temperature using the cold air within the chamber.

[0031] The controller is the command center of the refrigeration equipment, responsible for controlling the operation and temperature settings of each component. The controller can control the compressor's start / stop and operating time based on the set temperature to ensure the internal temperature of the refrigeration equipment remains stable within the set range. In demonstration mode, the controller prevents the compressor from operating; that is, in demonstration mode, the controller prevents the refrigeration components from working. The sensing components monitor the refrigeration chamber to obtain internal sensor data, while the communication module communicates with the cloud to send internal sensor data and receive information from the cloud.

[0032] To address the issues of cumbersome and inaccurate operation of the aforementioned demonstration mode switching methods, this application first proposes a control method for refrigeration equipment. Please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the control method for the refrigeration equipment of this application. Figure 1 As shown, the control method of the refrigeration equipment in this embodiment specifically includes steps S101 to S103:

[0033] Step S101: The refrigeration equipment uploads the internal sensor data to the cloud.

[0034] In this embodiment, the refrigeration device needs to communicate with the cloud through the communication module mentioned above. The communication connection method includes, but is not limited to, Bluetooth, Wi-Fi, and other connection methods. After the refrigeration device establishes a communication connection with the cloud through the communication module, the controller of the refrigeration device can use the sensing components to obtain the sensing data of the refrigeration chamber of the refrigeration device and upload it to the cloud through the communication module.

[0035] Step S102: The cloud determines the external environment information of the refrigeration equipment based on the internal sensor data and sends it back to the refrigeration equipment.

[0036] After receiving the sensor data from inside the refrigeration equipment, the cloud can analyze the external environment information of the refrigeration equipment based on the sensor data and send it back to the refrigeration equipment. The refrigeration equipment can receive the external environment information through the communication module and send it to the controller.

[0037] For example, taking a refrigerator as an example of a refrigeration device and a temperature sensor as an example of a sensing component, when the refrigerator uses the temperature sensor to upload the temperature data of the refrigerator's refrigeration cavity to the cloud, the cloud can analyze the differences in the food in the refrigerator's refrigeration cavity based on the temperature data of the refrigeration cavity. Through the differences in the food, the cloud can determine whether the refrigerator is currently in a store or in a user's home. After analyzing the external environment information of the refrigerator, the cloud can send it back to the refrigerator.

[0038] Step S103: The refrigeration equipment operates in demonstration mode or non-demonstration mode based on external environment information.

[0039] Once the controller of the refrigeration equipment receives external environmental information through the communication module, it can control the refrigeration equipment to operate in demonstration mode or non-demonstration mode.

[0040] As mentioned above, for example, taking a refrigerator, when the refrigerator's controller receives external environmental information in the store, the controller can control the refrigerator to turn on the demonstration mode and work in the demonstration mode; when the refrigerator receives external environmental information in the user's home, the controller can control the refrigerator to exit the demonstration mode and work in the non-demonstration mode, that is, work in the normal mode.

[0041] Compared to existing technologies that require manual activation or deactivation of demonstration modes via complex button combinations, this application's control method for the refrigeration equipment includes: the refrigeration equipment uploading internal sensor data to the cloud; the cloud determining the external environmental information of the refrigeration equipment based on the internal sensor data and transmitting it back to the refrigeration equipment; and the refrigeration equipment operating in demonstration mode or non-demonstration mode based on the external environmental information. Through this method, this application allows remote cloud control of the refrigeration equipment to operate in demonstration mode or non-demonstration mode, thereby reducing the difficulty of switching demonstration modes; furthermore, the cloud's determination of the external environmental information based on the refrigeration equipment's internal sensor data improves the accuracy of demonstration mode switching.

[0042] Optionally, the method by which the refrigeration equipment operates in demonstration mode or non-demonstration mode based on external environmental information is as follows: Figure 2 As shown, please refer to Figure 2 , Figure 2 yes Figure 1 A flowchart illustrating an embodiment of step S103. (See attached diagram.) Figure 2 As shown, this embodiment can be achieved through, as follows Figure 2 The steps shown in step S103 include steps S201 to S202:

[0043] Step S201: In response to external environmental information indicating that the store is inside, control the refrigeration equipment to operate in demonstration mode.

[0044] In this embodiment, when the cloud determines that the refrigeration equipment is currently in the store based on the sensor data inside the refrigeration equipment, the controller of the refrigeration equipment can control the refrigeration equipment to start the demonstration mode after receiving the external environment information that it is in the store through the communication module. The controller will then maintain the refrigeration equipment in the demonstration mode until the communication module receives the external environment information from the cloud again.

[0045] Step S202: In response to external environmental information indicating that the store is outside, control the refrigeration equipment to operate in non-demonstration mode.

[0046] When the cloud determines that the refrigeration equipment is currently outside the store based on the sensor data inside the refrigeration equipment, that is, when the cloud determines that the refrigeration equipment is in the user's home, the controller of the refrigeration equipment can control the refrigeration equipment to exit the demonstration mode and work in the non-demonstration mode after receiving the external environment information that it is outside the store through the communication module.

[0047] Optionally, based on the above embodiments, in this embodiment, the sensing component of the refrigeration equipment is configured as a temperature sensor or an infrared sensor. Please refer to... Figure 3 , Figure 3 yes Figure 1 A flowchart illustrating an embodiment of step S101. This embodiment can be achieved through, as shown in... Figure 3 The method shown implements step S101, specifically including steps S301 to S302:

[0048] Step S301: The refrigeration equipment periodically acquires the temperature data sequence of the refrigeration chamber using a temperature sensor or an infrared sensor.

[0049] When the sensing component of the refrigeration equipment is set as a temperature sensor or an infrared sensor, the controller of the refrigeration equipment can use the temperature sensor or infrared sensor to periodically obtain the temperature data sequence of the refrigeration chamber of the refrigeration equipment. That is, the controller can use the temperature sensor or infrared sensor to obtain the temperature data of the refrigeration chamber of the refrigeration equipment for a period of time as a temperature data sequence.

[0050] Step S302: Send the temperature data sequence to the cloud.

[0051] After the controller of the refrigeration equipment uses a temperature sensor or infrared sensor to obtain temperature data in the refrigeration chamber of the refrigeration equipment over a period of time as a temperature data sequence, it can send the temperature data sequence to the cloud through the communication module.

[0052] Optionally, based on Figure 3In this embodiment, please refer to the following example. Figure 4 , Figure 4 yes Figure 1 A flowchart illustrating an embodiment of step S102. This embodiment can be achieved through, as shown below... Figure 4 The method shown implements step S102, specifically including steps S401 to S403:

[0053] Step S401: The cloud performs calculations based on the temperature data sequence to obtain the temperature fluctuation amplitude of the temperature data sequence.

[0054] As mentioned earlier, when the sensing components of the refrigeration equipment are set as temperature sensors or infrared sensors, the sensing data obtained by the cloud is a temperature data sequence. After obtaining the temperature data sequence, the cloud can perform calculations based on the temperature data of the refrigeration equipment to obtain the temperature fluctuation amplitude of the temperature data sequence.

[0055] Step S402: In response to the temperature fluctuation amplitude being less than the preset fluctuation threshold, the cloud determines that the refrigeration equipment corresponding to the temperature data sequence is in the store.

[0056] The amount of food in the refrigeration chamber of a refrigeration device differs depending on whether it is in a retail store or a user's home. In a retail store, the refrigeration chamber contains almost no food, resulting in smaller temperature fluctuations. In a user's home, the refrigeration chamber contains more food, leading to larger temperature fluctuations.

[0057] Therefore, after obtaining the temperature fluctuation amplitude of the refrigeration equipment temperature data sequence, the temperature fluctuation amplitude can be compared with a preset fluctuation threshold to determine whether the refrigeration equipment is inside or outside the store (i.e., in the user's home). If the temperature fluctuation amplitude is less than the preset fluctuation threshold, the cloud can determine that the refrigeration equipment corresponding to the temperature data sequence is inside the store.

[0058] Step S403: In response to the temperature fluctuation amplitude being greater than or equal to the preset fluctuation threshold, the cloud determines that the refrigeration equipment corresponding to the temperature data sequence is outside the store.

[0059] After obtaining the temperature fluctuation amplitude of the temperature data sequence of the refrigeration equipment, the temperature fluctuation amplitude can be compared with the preset fluctuation threshold. If the temperature fluctuation amplitude is greater than or equal to the preset fluctuation threshold, the cloud can determine that the refrigeration equipment corresponding to the temperature data sequence is outside the store, that is, determine that the refrigeration equipment corresponding to the temperature data sequence is in the user's home.

[0060] Optionally, the cloud performs calculations based on the temperature data sequence to obtain the temperature fluctuation amplitude of the temperature data sequence, such as... Figure 5 As shown, please refer to Figure 5 , Figure 5 yes Figure 4 A flowchart illustrating an embodiment of step S401. This embodiment can be achieved through, as shown below... Figure 5 The method shown implements step S401, specifically including steps S501 to S503:

[0061] Step S501: The cloud performs smoothing processing on the temperature data sequence to obtain a smoothed temperature data sequence.

[0062] After acquiring the temperature data sequence, the cloud can perform a smoothing process to obtain a smoothed temperature data sequence. This smoothing process involves removing outliers from the temperature data sequence to reduce their impact.

[0063] Step S502: Obtain the maximum and minimum values ​​in the smoothed temperature data sequence.

[0064] After smoothing the temperature data sequence, the maximum and minimum values ​​can then be selected from the temperature data sequence.

[0065] Step S503: Calculate the temperature fluctuation amplitude based on the maximum and minimum values.

[0066] After obtaining the maximum and minimum values ​​in the temperature data sequence, the difference between the maximum and minimum values ​​can be calculated to obtain the temperature fluctuation amplitude.

[0067] For example, taking a refrigerator as an example of a refrigeration device, when the refrigerator's sensing component is set as a temperature sensor or an infrared sensor, the refrigerator's controller can use the temperature sensor or infrared sensor to obtain the temperature data sequence T = {T1, T2, T3, ..., Tn} of the refrigerator's cooling cavity, where Tn represents the temperature value collected at the nth time. After obtaining the temperature data sequence T, the controller can send it to the cloud through the communication module. The cloud can use a moving average method to smooth the temperature data sequence T to reduce some abnormal data, obtaining a smoothed temperature data sequence T′. At this time, the cloud can calculate the temperature fluctuation amplitude ΔT based on the smoothed temperature data sequence T′. After obtaining the temperature fluctuation amplitude ΔT, it can be compared with a preset fluctuation threshold to obtain the external environment information of the refrigerator and determine whether the refrigerator is in the store or in the user's home. After obtaining information about the refrigerator's external environment, the cloud can send it back to the refrigerator. When the refrigerator's controller receives information through the communication module that it is in the store, it controls the refrigerator to start the demonstration mode and work in the demonstration mode. When the refrigerator's controller receives information through the communication module that it is outside the store, it controls the refrigerator to exit the demonstration mode and work in the non-demonstration mode.

[0068] Optionally, this application further proposes a control method for a refrigeration device; please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is a schematic flowchart of a second embodiment of the control method for the refrigeration equipment of this application. In this embodiment, the sensing component of the refrigeration equipment is configured as a weight sensor. Figure 6 As shown, the control method of the refrigeration equipment in this embodiment specifically includes steps S601 to S605:

[0069] Step S601: The refrigeration equipment periodically uses a weight sensor to acquire weight sensing data of the refrigeration chamber of the refrigeration equipment and sends the weight sensing data to the cloud.

[0070] When the sensing component of the refrigeration equipment is set as a weight sensor, the controller of the refrigeration equipment can use the weight sensor to periodically acquire the weight sensing data of the refrigeration chamber of the refrigeration equipment, and send the weight sensing data to the cloud through the communication module.

[0071] Step S602: The cloud compares the weight sensing data with the preset weight threshold.

[0072] After acquiring the weight sensor data, the cloud can compare the weight sensor data with a preset weight threshold to determine whether the cooling equipment is inside or outside the store (i.e., in the user's home).

[0073] Step S603: In response to the weight sensor data being less than the preset weight threshold, the cloud determines that the refrigeration equipment corresponding to the weight sensor data is in the store.

[0074] The amount of food in the refrigeration chamber of a refrigeration device differs depending on whether it is in a retail store or a user's home. In a retail store, there is almost no food in the refrigeration chamber, resulting in a smaller weight sensor reading. In a user's home, there is more food in the refrigeration chamber, leading to a larger weight sensor reading for the refrigeration device.

[0075] Therefore, when the weight sensor data is less than the preset weight threshold, the cloud determines that the refrigeration equipment corresponding to the weight sensor data is in the store.

[0076] Step S604: In response to the weight sensor data being greater than or equal to a preset weight threshold, the cloud determines that the refrigeration equipment corresponding to the weight sensor data is outside the store.

[0077] When the weight sensor data is greater than or equal to the preset weight threshold, the cloud determines that the refrigeration equipment corresponding to the weight sensor data is outside the store, that is, it determines that the refrigeration equipment corresponding to the weight sensor data is in the user's home.

[0078] Step S605: The refrigeration equipment operates in demonstration mode or non-demonstration mode based on external environment information.

[0079] When the controller of the refrigeration equipment receives external environmental information from the cloud via the communication module indicating that it is in the store, it controls the refrigeration equipment to start the demonstration mode and work in the demonstration mode. When the controller receives external environmental information from the cloud via the communication module indicating that it is outside the store, i.e., in the user's home, it controls the refrigeration equipment to exit the demonstration mode and work in the non-demonstration mode.

[0080] Optionally, this application further proposes a control method for a refrigeration device; please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a flowchart illustrating a third embodiment of the control method for the refrigeration equipment according to this application. In this embodiment, the sensing component of the refrigeration equipment is configured as a vision sensor. Figure 7 As shown, the control method of the refrigeration equipment in this embodiment specifically includes steps S701 to S705:

[0081] Step S701: The refrigeration equipment periodically uses a vision sensor to acquire image data of the refrigeration chamber and sends the image data to the cloud.

[0082] When the sensing component of the refrigeration equipment is set as a vision sensor, the controller of the refrigeration equipment can use the vision sensor to periodically acquire image data of the refrigeration chamber of the refrigeration equipment and send the image data to the cloud.

[0083] Step S702: The cloud performs image recognition and analysis on the image data to determine whether the corresponding refrigeration equipment is in the store.

[0084] After acquiring image data, the cloud can use image recognition to analyze the image data to determine whether the corresponding refrigeration equipment is in the store.

[0085] As mentioned earlier, the amount of food in the refrigeration chamber of a refrigeration device differs depending on whether it's in a retail store or a customer's home. In a retail store, the refrigeration chamber contains almost no food, while in a customer's home, it contains a significant amount of food. Therefore, the cloud can identify the amount of food in the image data to determine whether the corresponding refrigeration device is in a retail store. If there is no food or only a small amount of food, the refrigeration device is determined to be in a retail store; if there is a significant amount of food, the refrigeration device is determined to be outside the retail store, i.e., in a customer's home.

[0086] Step S703: The refrigeration equipment operates in demonstration mode or non-demonstration mode based on external environment information.

[0087] When the controller of the refrigeration equipment receives external environmental information from the cloud via the communication module indicating that it is in the store, it controls the refrigeration equipment to start the demonstration mode and operate in the demonstration mode. When the controller receives external environmental information from the cloud via the communication module indicating that it is outside the store, i.e., in the user's home, it controls the refrigeration equipment to exit the demonstration mode and operate in the non-demonstration mode.

[0088] Unlike existing technologies, if the sensing components of the refrigeration equipment are set as visual sensors, the cloud will have a greater advantage in judging the differences between the food in the refrigeration chamber of the refrigeration equipment, and the judgment results will be more accurate.

[0089] Optionally, this application further proposes a refrigeration control system; please refer to [link to relevant documentation]. Figure 8 , Figure 8 This is a schematic diagram of the structure of an embodiment of the refrigeration control system of this application. Figure 8 As shown, the refrigeration control system 100 of this embodiment includes a cloud 10 and multiple refrigeration devices 20, and the cloud 10 is communicatively connected to the multiple refrigeration devices 20.

[0090] The refrigeration device 20 uploads internal sensor data to the cloud; the cloud 10 determines the external environment information of the refrigeration device 20 based on the internal sensor data and sends it back to the refrigeration device 20; the refrigeration device 20 operates in demonstration mode or non-demonstration mode based on the external environment information.

[0091] In this embodiment, the refrigeration equipment 20 can be equipped with a refrigerator, freezer, or other similar devices.

[0092] Optionally, based on Figure 8 For an example, please refer to the following: Figure 9 , Figure 9 This is a schematic diagram of the structure of an embodiment of the refrigeration equipment of this application. Figure 9 As shown, in this embodiment, the refrigeration device 20 includes a controller 21 and a refrigeration component 22, a sensing component 23, and a communication module 24 connected to the controller. The controller 21 controls the sensing component 23 to acquire the internal sensing data of the refrigeration device 20. The controller 21 sends the internal sensing data to the cloud through the communication module 24 and receives external environmental information from the cloud through the communication module 24. Based on the external environmental information, the controller 21 controls the refrigeration device 20 to work in demonstration mode or non-demonstration mode.

[0093] As mentioned above, the refrigeration component 22 in this embodiment is the core of the refrigeration device 20, responsible for generating cold air and controlling the internal temperature of the refrigeration device 20. The controller 21 can also control the start / stop and working time of the compressor according to the set temperature to ensure that the internal temperature of the refrigeration device 20 remains stable within the set range. The communication module 24 includes, but is not limited to, a Bluetooth module or a WiFi module, and is not limited here. The sensing component 23 includes any one or a combination of a temperature sensor, an infrared sensor, a weight sensor, or a vision sensor. That is, in this embodiment, the sensing component includes at least one of a sensor, an infrared sensor, a weight sensor, or a vision sensor. If the sensing component 23 includes any two or more of the above sensors, the cloud can more accurately determine the external environmental information of the refrigeration device 20 based on the internal sensing data.

[0094] Optionally, this application further proposes a readable storage medium. See also... Figure 10 , Figure 10 This is a schematic diagram of the structure of an embodiment of the readable storage medium of this application.

[0095] The readable storage medium 200 of this application embodiment stores program instructions 210, which are executed by a processor to implement the control method of the refrigeration device in any of the above embodiments.

[0096] Specifically, program instructions 210 can form a program file and be stored in the aforementioned storage medium as a software product, so that an electronic device (which may be a personal computer, server, or network device, etc.) or processor can execute all or part of the steps of the methods of the various embodiments of this application.

[0097] In this embodiment, the readable storage medium 200 may be, but is not limited to, a USB flash drive, SD card, PD optical drive, portable hard drive, large-capacity floppy drive, flash memory, multimedia memory card, server, etc.

[0098] In one embodiment, a computer program product or computer program is provided, comprising computer instructions stored in a readable storage medium. A processor of an electronic device reads the computer instructions from the readable storage medium and executes the computer instructions, causing the electronic device to perform the steps described in the above method embodiments.

[0099] Furthermore, if the aforementioned functions are implemented as software functions and sold or used as independent products, they can be stored in a mobile terminal-readable storage medium. That is, this application also provides a storage device storing program data, which can be executed to implement the methods of the above embodiments. This storage device can be, for example, a USB flash drive, an optical disc, or a server. In other words, this application can be embodied in the form of a software product, which includes several instructions to cause a smart terminal to execute all or part of the steps of the methods described in the various embodiments.
