BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.

[0073] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0076] Figure 3 A structural diagram of an electronic device provided in an embodiment of the present application. DETAILED DESCRIPTION

[0077] 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.

[0078] Since the embedded display screen will enter a dormant state after being unused for a period of time, the electronic device will not power the embedded display screen, and the embedded display screen will stop working. It is very inconvenient for the user to understand the operating status of the electronic device. To this end, the embodiments of the present invention provide a control method, device, electronic device and storage medium for a display screen.

[0079] The control method of the display screen in the embodiment of the present invention can be applied to smart devices, such as: a smart refrigerator or a cabinet air conditioner, etc. The smart device includes an embedded display screen, and the embedded display screen includes two working modes, one is a sleep mode, and the other is a screen saver mode. Each mode is respectively provided with a corresponding function switch. When any function switch is turned on, the display screen starts the corresponding working mode. When any function switch is turned off, the display screen starts the corresponding working mode. When the function switch corresponding to the sleep mode is turned on, the function switch corresponding to the screen saver mode is turned off. When the function switch corresponding to the screen saver mode is turned on, the function switch corresponding to the sleep mode is turned off. When the display screen enters the screen saver mode, the screen saver interface can be displayed.

[0080] In actual applications, users can choose to turn on sleep mode or screen saver mode according to actual needs. For example, if the user is away from home for a long time, they can choose to turn on sleep mode. If the user is at home, in order to understand the working status of the smart device, they can choose to turn on the low-power screen saver mode.

[0081] like Figure 1 As shown, the control method of the display screen includes:

[0082] Step S101, when the display screen of the device enters the screen saver interface, obtaining the interaction information input by the target interaction object during the last interaction recorded in the interaction record;

[0083] In an embodiment of the present invention, when a user does not use the display screen for a period of time, the display screen will automatically enter a screen saver interface. Predefined screen saver display information can be displayed in the screen saver interface. The screen saver display information can refer to time information, temperature information, etc., and can be set according to actual needs. The screen saver interface does not display information content other than the predefined screen saver display information to reduce the energy consumption required for the device to obtain information other than the screen saver display information.

[0084] An embodiment of the present invention records each interaction information between the interactive object and the device, and saves it in the interaction record. By way of example, the interaction information may refer to information used to control the increase or decrease of the output temperature of the smart cabinet, information used to control the increase or decrease of the temperature in the refrigerator's cold storage room or freezer, and so on.

[0085] The interactive information can be inputted via a remote controller, inputted on buttons on a panel, or inputted by a user through gesture operation.

[0086] In this step, when the display screen enters the screen saver interface, the interaction information recorded when the target interaction object interacted with the device most recently before the current moment can be queried in the interaction record according to the current moment.

[0087] Step S102, acquiring collected information output by an information collection device corresponding to the interactive information;

[0088] In the embodiment of the present invention, the information collection device may refer to a temperature sensor, etc. In order to detect the ambient temperature, a temperature sensor (such as a thermistor) may be installed at a structural position least affected by the internal temperature of the device, such as between the inner wall and the outer shell on the left or right side of the first-layer refrigeration chamber of a refrigerator, or between the inner wall and the outer shell on the left or right side of the air inlet of the internal machine of the cabinet, and between the inner wall and the outer shell at the bottom of the external machine fan, etc. If the temperature is greatly affected by the internal temperature of the device, then the surface in the direction of the inner wall is sprayed with a thermal insulation material, and a mesh outer shell with a small hemisphere protruding from this area is designed. The information collection device can be connected to the UART1 interface of the large-screen mainboard via a serial port line. Accordingly, when obtaining the collection information output by the information collection device, the voltage value of the thermistor used to measure the ambient temperature can be read via UART1.

[0089] In order to detect the temperature conditions inside the device, temperature sensors can be respectively set in the corresponding functional areas inside the device, such as a temperature sensor is set in the freezer and refrigerator of the refrigerator respectively, and then a serial port line is used to connect the main control board of the device to the UART2 interface of the large-screen mainboard, so as to establish a hardware connection for the software to read the data of various thermistors of the main control board and the status of the compressor. Accordingly, when obtaining the collection information output by the information collection device, the voltage value of the thermistor used to measure the internal temperature of the device and the status of the compressor can be read through UART2.

[0090] The data of various thermal sensors and the status of the compressor are as follows:

[0091] A. Read the voltage value of the thermistor embedded in the refrigerator's refrigerator compartment / warming room / freezer compartment;

[0092] B. Read the voltage value of the thermal sensor of the cabinet air outlet / interior pipe / exterior pipe;

[0093] C. If the inner / outer temperature sensor of the device is slightly affected by the internal environment, it can also be read as the ambient temperature.

[0094] D. Read the compressor status of the device: When the system does not reach the expected temperature Typ±1℃, the compressor is powered on and displayed as running; otherwise, the compressor is powered off and displayed as standby.

[0095] In actual applications, after interacting with a device, a user may need to observe whether the device has been operated according to the control of the interaction information. Therefore, in an embodiment of the present invention, a corresponding relationship between the interaction information and the information collection device can be established in advance.

[0096] For example, if the interactive information is information for controlling the temperature in the space where the smart cabinet is located to increase or decrease, then the information collection device corresponding to the interactive information is a temperature sensor disposed at the air inlet and outlet of the smart cabinet;

[0097] If the interactive information is information for detecting whether the internal temperature of the intelligent cabinet is abnormal, the information collection device corresponding to the interactive information is a temperature sensor arranged in the internal pipe / external pipe;

[0098] For another example: if the interactive information is information for controlling the increase or decrease of the output temperature of the refrigerator compartment, then the information collection device corresponding to the interactive information is a temperature sensor disposed in the refrigerator compartment;

[0099] If the interactive information is information for controlling the increase or decrease of the output temperature of the freezer compartment of the refrigerator, the information collection device corresponding to the interactive information is a temperature sensor or the like disposed in the freezer compartment of the refrigerator.

[0100] Step S103, controlling the display screen of the device to display the collected information on the screen saver interface.

[0101] The read voltage value can be converted into a temperature value based on the corresponding relationship between resistance, voltage and temperature.

[0102] The corresponding relationship between resistance, voltage and temperature is as follows:

[0103] A. Thermistor: When the temperature rises, the resistance decreases accordingly, causing the voltage to decrease.

[0104] B. Thermistor: When the temperature drops, the resistance increases accordingly, causing the voltage to increase.

[0105] C. Different types of thermistors have different ranges of resistance change.

[0106] For example, at a room temperature of 25°C, the resistance value of a thermistor is 2.005kΩ and the voltage value is 901mV.

[0107] When the temperature rises to 26°C, the resistance value becomes: 1.919kΩ, and the voltage value becomes: 881mV;

[0108] When the temperature drops to 24°C, the resistance value becomes: 2.094kΩ, and the voltage value becomes: 921mV.

[0109] In an embodiment of the present invention, the content displayed on the display screen may include collected information and other predefined information to facilitate users to understand the operation status of the device, such as: displaying the current time / indoor temperature / outdoor temperature / device-related status on the screen saver interface.

[0110] The embodiment of the present invention detects whether there are interactive objects around the device. If not, it controls the display screen to enter the screen saver interface, obtains the interaction information of the last interaction, and obtains the collection information output by the information collection device corresponding to the interaction information, and finally controls the display screen to display the collection information on the screen saver interface.

[0111] The embodiment of the present invention can control the device to enter the screen saver interface when there are no interactive objects around the device, and can obtain the collected information output by the corresponding information collection device based on the interaction information of the last interaction in the interaction record, and finally control the display screen to display the collected information on the screen saver interface. The embodiment of the present invention can facilitate the user to understand the working status of the device at any time when the device enters the screen saver interface, and can obtain the collected information output by the information collection device corresponding to the interaction information based on the interaction information of the user's last interaction with the device, thereby realizing the display of the collected information output by the information collection device that the user may be more concerned about, which is convenient for user use.

[0112] In another embodiment of the present invention, step S101 obtains the target interaction object of the last interaction recorded in the interaction record, including:

[0113] Step 201, controlling the scanning device to transmit a scanning signal to a target area around the device;

[0114] In the embodiment of the present invention, the device periphery may refer to a designated area centered on the device, such as: an area radiated during the operation of the device or an area where the device can be controlled, such as: a cooling / heating area of ​​a smart cabinet, an area in front of a refrigerator control panel for users to stand, etc. The interactive object may refer to a user, etc. The scanning device may refer to a millimeter wave radar, etc.

[0115] In this step, whether there is an interactive object can be determined every preset time period (such as 1 second or 2 seconds, etc.) by detecting whether there is an interactive object in the area radiated during the operation of the millimeter wave radar or other detection equipment, or by detecting whether a trigger operation is detected on the control panel of the device.

[0116] For example, during the operation of the device, the millimeter wave radar can be controlled to scan the surroundings of the device. If a living person is scanned, it is determined that there is an interactive object around the device. Otherwise, there is no interactive object around the device.

[0117] In an embodiment of the present invention, different target areas can be pre-set according to different devices, such as: the target area of ​​the smart cabinet can be an area within a certain radius centered on the control panel, a direct cooling / heating area (an area that the air outlet can blow directly or indirectly), or an area within a certain radius centered on the control panel of the refrigerator, etc.

[0118] In order to prevent pets and children from affecting the detection results, you can select an area with a scanning height above a preset height (e.g. 100 cm) when setting the target area.

[0119] The millimeter-wave radar transmits a scanning signal to the target area. If there is an interactive object in the target area, the scanning signal will be reflected back after encountering a living object. If there is no living object in the target area, the scanning signal will be reflected back after encountering an obstacle. Based on the reflected signal, it can be determined whether there is a living object in the target area.

[0120] Step 202: if an interactive object is detected in the target area, an interactive object in the interaction record that matches the object information of the interactive object is determined as a target interactive object;

[0121] Step 203: If no interactive object is detected in the target area, determine the interactive object that interacted with the device last time in the interaction record as the target interactive object.

[0122] The embodiment of the present invention can, when an interactive object is detected in the target area, determine the interactive object in the interaction record that matches the object information of the interactive object as the target interactive object; if no interactive object is detected, determine the interactive object that last interacted with the device in the interaction record as the target interactive object, thereby achieving the determination of the target interactive object and providing a basis for the device to obtain which interactive information. By distinguishing different target interactive objects, different collection information can be displayed for different target interactive objects, so that different target interactive objects can view the collection information that they are more concerned about, which is convenient for users to use.

[0123] In another embodiment of the present invention, step 101 of obtaining the target interaction object of the last interaction recorded in the interaction record includes:

[0124] Step 301, determining whether a trigger operation is detected on an interactive key of a device;

[0125] In the embodiment of the present invention, a plurality of interactive buttons may be pre-set on the control panel of the device to facilitate the user to input interactive information.

[0126] When the user presses any button, it can be determined that an interactive object is detected around the device.

[0127] For example, during the operation of the device, it can be detected whether a trigger operation is detected on an interactive button on the control panel of the device. If a trigger operation is detected, it is determined that there are interactive objects around the device; otherwise, there are no interactive objects around the device.

[0128] Step 302: if a trigger operation is detected on the interactive button of the device, it is determined that there are interactive objects around the device that interact with the device, and an interactive object in the interaction record that matches the object information of the interactive object is determined as a target interactive object;

[0129] Step 303: If no trigger operation is detected on the interaction button of the device, the interaction object that interacted with the device last time in the interaction record is determined as the target interaction object.

[0130] The embodiment of the present invention can determine that there are interactive objects around the device when a trigger operation is detected on the interactive button, and determine that there are no interactive objects around the device when no trigger operation is detected on the interactive button of the device, and determine the interactive object that last interacted with the device in the interaction record as the target interactive object, thereby achieving the determination of the target interactive object and providing a basis for the device to obtain which interactive information. By distinguishing different target interactive objects, different collection information can be displayed for different target interactive objects, so that different target interactive objects can view the collection information that they are more concerned about, which is convenient for users to use.

[0131] In another embodiment of the present invention, step 103 of acquiring collected information output by an information collection device corresponding to the interaction information includes:

[0132] Step 401, extracting an interaction category identifier from the interaction information;

[0133] In an embodiment of the present invention, the interaction information may include an interaction category identifier and interaction content. The interaction category may include: adjusting the temperature of a first location (such as a refrigerator), adjusting the temperature of a second location (such as a freezer), adjusting the indoor temperature, or detecting anomalies, etc. The corresponding interaction category identifiers may be 01, 02, 03, and 04, etc. Table 1 below shows the correspondence between interaction categories and information collection devices.

[0134] Table 1

[0135]

[0136]

[0137] Step 402, based on the preset correspondence between the interaction category and the information collection device, searching for the device identifier corresponding to the interaction category identifier;

[0138] Step 403: Acquire the collected information output by the information collection device corresponding to the device identifier.

[0139] In an embodiment of the present invention, an information collection device can be searched based on the correspondence between a preset interaction category and the information collection device, and then the collection information output by the information collection device can be obtained, thereby facilitating the display of the collection information associated with the interaction information of the user's last interaction, making it easier for the user to understand the information they are concerned about during the operation of the device and facilitating user use.

[0140] In another embodiment of the present invention, step 104 controls the display screen of the device to display the collected information on the screen saver interface, including:

[0141] Step 501, determining whether the collected information is within a first threshold range corresponding to the information collection device;

[0142] Since the information collection devices set at different positions are used to measure temperatures in different ranges, for example, the numerical ranges of the temperature values ​​output by the information collection device set in the refrigerator's refrigerator compartment and the information collection device set in the refrigerator's freezer compartment will be different, the corresponding first threshold range can be set in advance for the information collection devices at different setting positions according to the setting positions of the information collection devices.

[0143] Step 502: If the collected information is within the first threshold range, control the display screen to display the collected information in a first display manner;

[0144] In an embodiment of the present invention, the first display mode may refer to the font color, background color or flickering, etc. For example, when the collected information is within the first threshold range, the font color is white, the background color is black, and there is no flickering.

[0145] Step 503: If the collected information is outside the first threshold range corresponding to the information collection device, control the display screen to display the collected information in a second display manner.

[0146] In order to distinguish whether the collected information is within the first threshold range or outside the first threshold range, that is, to distinguish whether the collected information is normal or abnormal, the second display method is different from the first display method. For example, when the collected information is outside the first threshold range, the font color is red, the background color is black, and it does not flash.

[0147] In actual applications, a voice broadcast module can be set in the device. When the collected information is outside the first threshold range corresponding to the information collection device, the voice broadcast module can be controlled to give a voice broadcast warning prompt to remind the user that the information collection device used to collect the collected information is located at a location where the temperature is abnormal.

[0148] In actual applications, when the user completes the operation on the screen, leaves the device, and the set sleep time is reached, the system reads the voltage value of the thermistor inside the device and the status of the compressor through the serial port UART2, converts it into a temperature value based on the corresponding relationship between resistance-voltage-temperature, and displays it in white font (within the first threshold range, normal) or in red font (outside the first threshold range, abnormal).

[0149] For example, in a smart refrigerator, the refrigerator compartment on the first layer generally operates between +2°C and +8°C, the temperature change chamber on the second layer generally operates between -7°C and +5°C, and the freezer compartment on the third layer generally operates between -24°C and -16°C.

[0150] In automatic mode or manually set the target temperature to 5°C, when the thermistor set in the refrigerator reads a temperature of 6°C, white fonts are displayed, and the area is operating normally; when the thermistor set in the refrigerator reads a temperature of 12°C, red fonts are displayed, and the area is operating abnormally. Check whether the door is closed tightly. If the expected temperature of 5±1°C is not reached for more than 8 hours, consult after-sales maintenance.

[0151] In another embodiment of the present invention, step 104 controls the display screen of the device to display the collected information on the screen saver interface, including:

[0152] Step 601, if two information collection devices corresponding to the interactive information are obtained, based on the correspondence between the device association relationship and the second threshold range, obtain the second threshold range corresponding to the association relationship between the two information collection devices corresponding to the interactive information;

[0153] In actual applications, if the interactive information is used to control the temperature increase or decrease in the space where the smart cabinet is located, the information collection device corresponding to the interactive information is a temperature sensor arranged at the air inlet and outlet of the smart cabinet. At this time, it can be determined that two information collection devices corresponding to the interactive information are obtained.

[0154] In the embodiment of the present invention, the corresponding relationship between the device association relationship and the second threshold range may be preset, as shown in Table 2 below:

[0155] Table 2

[0156]

[0157] Step 602, calculating the difference between the collected information output by the two information collection devices;

[0158] Step 603, determining whether the difference is within a second threshold range;

[0159] Step 604: If the difference is within the second threshold range, control the display screen to display the collected information in a third display manner;

[0160] Step 605: If the difference is outside the second threshold range, control the display screen to display the collected information in a fourth display manner.

[0161] In the embodiment of the present invention, the third display mode may be the same as or different from the first display mode, and the fourth display mode may be the same as or different from the second display mode.

[0162] In actual applications, a voice broadcast module can be set in the device. When the collected information is outside the first threshold range corresponding to the information collection device, the voice broadcast module can be controlled to give a voice broadcast warning prompt to remind the user that the information collection device used to collect the collected information is located at a location where the temperature is abnormal.

[0163] For example, on a smart cabinet, the temperature difference between the air outlet and the air inlet in the cooling mode is generally not less than 8°C, and the temperature difference between the air outlet and the air inlet in the heating mode is generally not less than 20°C. Under normal circumstances, the outdoor unit operates normally between an ambient temperature of -20°C and +48°C.

[0164] Set the cooling mode to 26℃ when the indoor temperature is 28℃. When the outlet temperature is 18℃ and the indoor temperature is 28℃, white fonts are displayed and the area is operating normally. When the outlet temperature is 24℃ and the indoor temperature is 25℃, red fonts are displayed and the area is operating abnormally. Check whether the internal temperature of the cabinet is normal. If it continues for more than 1 hour and still does not reach the expected temperature of 26±1℃, consult after-sales maintenance.

[0165] In another embodiment of the present invention, before step 104 controls the display screen of the device to display the collected information on the screen saver interface, the method further includes:

[0166] Step 701, obtaining the collection information obtained at the last collection moment;

[0167] In the embodiment of the present invention, each time the collected information is obtained, the collection time corresponding to each piece of collected information is obtained. In practical applications, for example, the interval between the collection times may be 1 second or 2 seconds.

[0168] Step 702, comparing the collected information obtained at the previous collection moment with the collected information obtained at the current moment;

[0169] Step 703: If the difference between the collected information obtained at the last collection moment and the collected information obtained at the current moment is greater than a preset threshold, a step of controlling the display screen of the device to display the collected information on the screen saver interface is executed.

[0170] In the embodiment of the present invention, the collected information may be displayed only when the change between adjacent collection moments exceeds a preset threshold, for example, when the change value of any temperature sensor is greater than or equal to 1° C., it is automatically updated.

[0171] Example 1: On a smart refrigerator, when the user sets the desired temperature of the refrigerator compartment / humidity chamber / freezer compartment to 5°C / 0°C / -20°C (or the default value of the automatic mode), the device will be left to sleep when the screen goes to sleep. The information is displayed in the low power mode of the screen saver as follows:

[0172] Current time: 2021-03-30 09:00:00;

[0173] Indoor temperature: 26℃ Cooling status: standby;

[0174] Refrigerator on the first floor: 5℃ (Typ: 5℃);

[0175] The second layer of temperature-changing chamber: 1℃ (Typ: 0℃);

[0176] The freezer on the third floor: -21°C (Typ: -20°C);

[0177] When the refrigerator door is opened or closed, the relevant thermistor senses the temperature change, and the refrigerator temperature changes to 12°C. If the other conditions remain unchanged or change by less than 1°C, it will automatically update to:

[0178] Current time: 2021-03-30 10:00:00;

[0179] Indoor temperature: 26℃ Cooling status: running;

[0180] Refrigerator on the first floor: 12℃ (Typ: 5℃);

[0181] The second layer of temperature-changing chamber: 1℃ (Typ: 0℃);

[0182] Freezer room on the third floor: -21°C (Typ: -20°C).

[0183] Example 2: On a smart cabinet, when the user sets the desired temperature of the cooling mode to 26°C (or the default value of the automatic mode), when the device reaches the screen sleep time, the information is displayed in the low power mode of the screen saver as follows:

[0184] Current time: 2021-03-31 11:00:00;

[0185] Indoor temperature: 28℃ (Typ: 26℃) Cooling / Heating: Running;

[0186] Outdoor temperature: 30℃ Outdoor unit temperature: 36℃;

[0187] Outlet air temperature: 18°C ​​Indoor unit temperature: 15°C;

[0188] After the air conditioner is turned on for a while, the indoor temperature becomes 25°C, the outlet temperature becomes 24°C, the indoor pipe temperature becomes 26°C, the outdoor temperature becomes 31°C, and the outdoor pipe temperature becomes 32°C, then it will automatically update to:

[0189] Current time: 2021-03-31 11:30:00;

[0190] Indoor temperature: 25℃ (Typ: 26℃) Cooling / Heating: Standby;

[0191] Outdoor temperature: 31℃ Outdoor unit temperature: 32℃;
