[0001] This disclosure relates to the field of terminal technology, and in particular to a method and apparatus for switching the display interface of a display device. Background Technology

[0002] With the aging of the agricultural population, tobacco growers and technicians are increasingly becoming predominantly elderly. Most newly built tobacco curing barns are now equipped with display devices, significantly improving ease of operation.

[0003] However, the screen size of the display devices currently installed in tobacco curing barns is limited. In order to display the main information, most of the parameter information is displayed in small font. Elderly people have to stand in front of the display device to see the data on the screen, which results in low operating efficiency and poor user experience. Summary of the Invention

[0004] This disclosure provides a method and apparatus for switching the display interface of a display device, so as to realize automatic switching of the display interface, effectively reduce display jitter caused by frequent switching, and achieve the effects of improving display stability, improving user experience, and enhancing the intelligence and convenience of interaction.

[0005] In a first aspect, embodiments of this disclosure provide a method for switching the display interface of a display device, the method comprising: Receive the first distance information between the target object and the display device; When the first distance information and the first preset distance threshold meet the first condition, the first screen information continues to be displayed based on the display device; When the first distance information and the second preset distance threshold meet the second condition, a processing result for switching the display screen is generated, and the interface switching control signal is sent to the controller. Based on the controller, the display device is controlled to switch from the first screen information to the second screen information; Both the first and second screen information display environmental information of the tobacco curing barn, and the display size of the environmental information differs.

[0006] Secondly, embodiments of the present invention also provide a display interface switching device for a display device, the device comprising: The first distance information receiving module is used to receive the first distance information between the target object and the display device; The first screen information display module is used to continue displaying the first screen information based on the display device when the first distance information and the first preset distance threshold meet the first condition; The interface switching control signal sending module is used to generate a processing result of switching display screen when the first distance information and the second preset distance threshold meet the second condition, and send the interface switching control signal to the controller; The screen information switching module is used to control the display device to switch from the first screen information to the second screen information based on the controller; Both the first and second screen information display environmental information of the tobacco curing barn, and the display size of the environmental information differs.

[0007] Thirdly, embodiments of the present invention also provide an electronic device, the electronic device comprising: One or more processors; Storage device for storing one or more programs.

[0008] Fourthly, embodiments of the present invention also provide a storage medium containing computer-executable instructions, which, when executed by a computer processor, are used to perform a display interface switching method of a display device as described in any of the embodiments of the present invention.

[0009] Fifthly, embodiments of the present invention also provide a computer program product, including a computer program, characterized in that, when executed by a processor, the computer program implements the display interface switching method of a display device as described in any embodiment of the present invention.

[0010] The technical solution of this disclosure embodiment involves a display device deployed at a preset location in a tobacco curing barn. The display device integrates a processor and a controller. Based on the processor's processing results, an interface switching control signal is sent to the controller, causing the controller to perform a display interface switching operation. The processor determines the processing result using the following method: First, it receives first distance information between the target object and the display device. Then, when the first distance information and a first preset distance threshold satisfy a first condition, the display device continues to display first screen information. Further, when the first distance information and the second preset distance threshold satisfy a second condition, a processing result for switching the display screen is generated, and an interface switching control signal is sent to the controller. Finally, the controller controls the display device to switch from the first screen information to the second screen information. Both the first and second screen information display environmental information from the tobacco curing barn, and the display sizes of the environmental information differ. This solves the problem in existing technologies where elderly people must stand in front of the display device to see the data on the screen, resulting in low operational efficiency and a poor user experience. This disclosure implements a threshold condition-controlled switching logic to control the screen information of the display device, thereby achieving automatic switching of the display interface. This effectively reduces display jitter caused by frequent switching, thereby improving display stability, user experience, and the intelligence and convenience of interaction.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0014] Before introducing the technical solutions provided in the embodiments of this disclosure, the application scenarios can be illustrated first. The technical solutions provided in the embodiments of this disclosure can be applied to scenarios where the display interface of a display device needs to be switched. For example, for a target display device deployed at a preset location in a tobacco curing barn, it can be applied to a scenario where the display interface of the target display device needs to be switched. Based on the technical solutions of the embodiments of this disclosure, the switching logic is controlled by threshold conditions to control the screen information of the display device, thereby realizing automatic switching of the display interface. This can effectively reduce display jitter caused by frequent switching, thereby improving display stability, enhancing user experience, and improving the intelligence and convenience of interaction.

[0015] Example 1 Figure 1 This is a flowchart illustrating a display interface switching method for a display device provided in an embodiment of this disclosure. This embodiment is applicable to situations where the display interface of a display device is switched. The method can be executed by a display interface switching device for the display device. This device can be implemented in the form of software and / or hardware. The hardware can be a mobile electronic device. This electronic device can execute the display interface switching method for the display device provided in this technical solution.

[0016] like Figure 1 As shown, the display device is deployed at a preset position in the tobacco curing barn. The display device integrates a processor and a controller. Based on the processing result of the processor, it sends an interface switching control signal to the controller, so that the controller performs a display interface switching operation based on the interface switching control signal. The processor determines the processing result based on the following method: S110, Receive the first distance information between the target object and the display device.

[0017] The preset location can be approximately 1.5 meters away from the pedestrian walkway of the tobacco curing barn. A tobacco curing barn is a room used for curing or drying tobacco leaves. Tobacco curing barns are built with standardized structures, allowing for batch curing with high tobacco density. They typically possess good insulation and sealing, stable hot air circulation, and dehumidification capabilities, and use automatic control to achieve the curing process curves of "heating—constant temperature—dehumidification." The display device integrates a processor module responsible for calculation or decision-making and a controller module responsible for executing control actions. After the processor calculates the result, it generates an interface switching control signal that determines how the interface should switch, and sends this signal to the controller. Upon receiving this interface switching control signal, the controller switches the screen display from the current page to the target page according to the signal's requirements.

[0018] It should be noted that the target object refers to the personnel observing or approaching the display device. Specifically, this refers to the personnel in the tobacco curing barn who walk to the display device to view data and operate it. The initial distance information refers to the distance between the target object and the display device. This initial distance information can be measured using a distance sensor. The distance sensor can be installed on the display device itself. Furthermore, a human body sensor can also be installed on the display device to determine the presence of the target object.

[0019] Optionally, if the first distance information of the target object is not received within a preset time period, the screen will be turned off.

[0020] It should be noted that the preset duration refers to a pre-set period of time. For example, the preset duration can be 30 seconds or 1 minute. Failure to receive the first distance information of the target object means that no first distance information was reported or updated during the preset duration. Possible reasons include: the human body sensor did not detect the target object, or the target object was too far from the display device, exceeding the distance detection range.

[0021] Specifically, the processor receives initial distance information between the target object and the display device. If the system does not receive this initial distance information within a pre-defined time period, it will turn off or shut down the screen display.

[0022] S120: When the first distance information and the first preset distance threshold meet the first condition, the first screen information continues to be displayed based on the display device.

[0023] Optionally, if the first distance information is greater than the first preset distance threshold, the first preset distance threshold is greater than the second preset distance threshold; if the first distance information is close to a display device, the first preset distance threshold is less than the second preset distance threshold.

[0024] Among them, the nearest neighbor is used to reflect that the first distance information between the target object and the display device is less than the first preset distance threshold.

[0025] It should be noted that, see Figure 2 When the first distance information from the target object to the display device is greater than the first preset distance threshold, the first preset distance threshold is greater than the second preset distance threshold.

[0026] It should also be noted that, see Figure 3 When the target object is close to the display device according to the first distance information, the first preset distance threshold is less than the second preset distance threshold. Furthermore, the first distance information is less than the first preset distance threshold.

[0027] Specifically, when the first distance information from the target object to the display device is greater than the first preset distance threshold and the first preset distance threshold is greater than the second preset distance threshold, the first screen information continues to be displayed based on the display device; when the first distance information is close to the display device, that is, when the first distance information between the target object and the display device is less than the first preset distance threshold and the first preset distance threshold is less than the second preset distance threshold, the first screen information continues to be displayed based on the display device.

[0028] S130: When the first distance information and the second preset distance threshold meet the second condition, generate the processing result of switching the display screen and send the interface switching control signal to the controller.

[0029] In this embodiment, if the first distance information is greater than the first preset distance threshold and the first distance information is greater than the second preset distance threshold during continuous movement, then the first screen information associated with the first preset distance threshold will continue to be displayed.

[0030] It should be noted that, see Figure 2 If the first distance information is greater than the first preset distance threshold, as the target object continues to move closer to the display device, as long as the first distance information is greater than the second preset distance threshold, the first screen information associated with the first preset distance threshold will continue to be displayed.

[0031] Optionally, the information displayed on the first screen may include at least one or more of the following: target temperature, actual temperature, and fault information.

[0032] See Figure 4The target temperature includes both dry-bulb and wet-bulb target temperatures. Dry-bulb temperature refers to the air temperature measured by a standard temperature sensor, without considering the effects of evaporative cooling. Wet-bulb temperature is a temperature index related to air humidity, commonly used for humidity or evaporation intensity control in the tobacco curing process. The target temperature is the set temperature that the system wants the tobacco curing barn to reach and maintain, usually determined by the process curve or stage parameters. Actual temperature includes both dry-bulb and wet-bulb actual temperatures. Actual temperature is the real-time temperature currently measured by the sensor. If a fault exists, the fault information will be displayed on the first screen. For example, the fault information could be "no fan current," meaning the system detects that the fan current is 0 or abnormal, triggering an alarm or fault notification.

[0033] During the movement, if the first distance information is less than or equal to the second preset distance threshold, a processing result for switching the display screen is generated to display the second screen information.

[0034] It should be noted that, see Figure 2 When the first distance information is less than or equal to the second preset distance threshold, that is, when the distance from the target object to the display device is less than the second preset distance threshold, the processing result of switching the display screen is generated to display the second screen information.

[0035] Optionally, the information on the second screen may include at least one or more of the following: target temperature, actual temperature, fault information, baking process curve, power supply voltage, cold air damper status, circulating fan status, burner status, baking stage, running time, and date.

[0036] The second image information is related to the image associated with the second preset distance threshold.

[0037] It should be noted that, see Figure 5 , Figure 5 This is information from the second screen. Figure 5 The baking process curve in the image shows the changes in dry-bulb and wet-bulb temperatures as time and stages progress. The curve also includes the duration of each stage. This curve allows users to visually see the current baking progress, the subsequent temperature trends, and the duration of each stage. The numbers on the broken lines of the curve, such as 36, 38, 40, and 42, represent the target temperature values ​​for that node. The stage times below the curve, such as 2, 10, and 24, indicate the number of hours or unit of time that segment of the process lasts.

[0038] It should also be noted that power supply voltage refers to the voltage value of the control system or power source, used to determine whether the power supply is normal. Low power supply voltage or a missing phase may cause malfunctions in the fan or burner. The cold air damper status refers to the open / closed state of the dampers related to cold air intake or exhaust. The cold air damper status affects temperature and humidity regulation and dehumidification efficiency. Opening the cold air intake dampers usually introduces cold air, thereby enhancing dehumidification and cooling. The circulating fan is used to circulate hot air within the drying chamber, improving temperature and humidity uniformity. The circulating fan status can include stopped, low speed, high speed, or malfunction. The burner provides the heat source for the drying chamber. The burner status can include normal, running, stopped, igniting, flameout, abnormal flame, or temperature control output. The entire drying process can be divided into several drying stages, such as: heating, yellowing, color setting, drying the ribs, etc., or custom stages 1 / 2 / 3, etc. Figure 5 The display above shows stage 3, indicating that the current baking stage is in stage 3. Runtime refers to the duration of operation from the start of baking to the current running time, or the runtime of the current stage. Figure 5 The top area displays the running time and remaining time. The running time can be used to assess progress, schedule inspections, and predict completion times. The date is used to record the current system time, facilitating fault tracking and process record alignment.

[0039] If the first distance information is close to the display device, and the first distance information is less than the first preset distance threshold, and continues to be less than the second preset distance threshold during the movement, then the first screen information will continue to be displayed.

[0040] Among them, the first image information is related to the image associated with the first preset distance threshold.

[0041] It should be noted that, see Figure 3 If the first distance information is near a display device, and the first distance information is less than a first preset distance threshold, and remains less than a second preset distance threshold during movement, then the first screen information will continue to be displayed. At this time, the content of the first screen information includes at least one or more of the following: target temperature, actual temperature, fault information, baking process curve, power supply voltage, cold air damper status, circulating fan status, burner status, baking stage, running time, and date.

[0042] During the movement, if the first distance information is greater than or equal to the second preset distance threshold, a processing result for switching the display screen is generated to display the second screen information.

[0043] The second image information is related to the image associated with the second preset distance threshold.

[0044] It should be noted that when the target object moves from a nearby display device to a device farther away, see [reference needed]. Figure 3When the first distance information is greater than or equal to the second preset distance threshold, a processing result for switching the display screen is generated to display the second screen information. At this time, the content of the second screen information includes at least one or more of the following: target temperature, actual temperature, and fault information.

[0045] Specifically, if the first distance information is greater than a first preset distance threshold, and during continuous movement, the first distance information is greater than a second preset distance threshold, then the first screen information associated with the first preset distance threshold will continue to be displayed. If, during movement, the first distance information is less than or equal to the second preset distance threshold, a switching screen processing result will be generated to display the second screen information. If the first distance information is close to a display device, and the first distance information is less than the first preset distance threshold, and during movement, it remains less than the second preset distance threshold, then the first screen information will continue to be displayed. If the first distance information is greater than or equal to the second preset distance threshold, a switching screen processing result will be generated to display the second screen information.

[0046] S140, The controller controls the display device to switch from the first screen information to the second screen information.

[0047] Both the first and second screens display environmental information about the tobacco curing barn, but the display sizes of the environmental information differ.

[0048] Specifically, based on the processor's processing results, an interface switching control signal is sent to the controller, so that the controller performs a display interface switching operation based on the interface switching control signal, that is, the controller controls the display device to switch from the first screen information to the second screen information.

[0049] The technical solution of this disclosure embodiment involves a display device deployed at a preset location in a tobacco curing barn. The display device integrates a processor and a controller. Based on the processor's processing results, an interface switching control signal is sent to the controller, causing the controller to perform a display interface switching operation. The processor determines the processing result using the following method: First, it receives first distance information between the target object and the display device. Then, when the first distance information and a first preset distance threshold satisfy a first condition, the display device continues to display first screen information. Further, when the first distance information and the second preset distance threshold satisfy a second condition, a processing result for switching the display screen is generated, and an interface switching control signal is sent to the controller. Finally, the controller controls the display device to switch from the first screen information to the second screen information. Both the first and second screen information display environmental information from the tobacco curing barn, and the display sizes of the environmental information differ. This solves the problem in existing technologies where elderly people must stand in front of the display device to see the data on the screen, resulting in low operational efficiency and a poor user experience. This disclosure implements a threshold condition-controlled switching logic to control the screen information of the display device, thereby achieving automatic switching of the display interface. This effectively reduces display jitter caused by frequent switching, thereby improving display stability, user experience, and the intelligence and convenience of interaction.

[0050] Example 2 As an optional embodiment of the present invention, an example is provided to further illustrate the invention.

[0051] It should be noted that, see Figure 6 Upon initial entry, a timer is started, and then the system continuously checks whether a target object is detected in front of the display device. If a target object is detected, the system enters the information display interface switching process and ends. If no target object is detected, the system continues to check for timeout. If the timeout is not exceeded, the system returns to continue detecting the target object. If the timeout is exceeded, the system enters the screen saver interface, and then enters the information display interface switching process again and exits.

[0052] The information display interface includes two modes: a "concise large font display mode" and a "holographic small font display mode." The concise large font display mode highlights the most important information about the device, including target temperature, actual temperature, and fault information, using a large font. Other information is simplified or omitted, using a small font. The holographic small font display mode, following industry standards, displays all major operating information, including target temperature, actual temperature, fault information, baking process curve, power supply voltage, cold air damper status, circulating fan status, burner status, baking stage, running time, and date. To display all information, the font is small, making it generally only easily visible to elderly users who are operating the display at close range.

[0053] It should also be noted that participation Figure 7 First distance information: symbol Dmmi. When a person is detected by the human body sensor, the distance between the target object detected by the ranging sensor and the display device is the first distance information. If no target object is detected, the detection result of the ranging sensor is invalid, and the first distance information can also be considered as infinity. Reference distance: symbol Dref. The standard for distinguishing between long and short distances. Ideally, when the distance between the target object and the display device is greater than the reference distance, a "simple large font display mode" is used; when the distance between the target object and the controller is less than the reference distance, a "holographic small font display mode" is used. Hysteresis distance: symbol Dhys. When the distance between the target object and the display device is near the reference distance, a hysteresis distance is set to prevent the display interface from switching back and forth. Parameter values ​​can be set on the display device, for example, reference distance Dref is 1 meter, and hysteresis distance Dhys is 0.2 meters. During power-on initialization, if "first distance information Dmmi > reference distance Dref" is detected, the "simple large font display mode" is used; otherwise, the "holographic small font display mode" is used. During operation, if the "human-machine distance Dmmi < reference distance Dref - hysteresis distance Dhys" is detected while in "simple large font display mode", the system switches to "holographic small font display mode". If the "human-machine distance Dmmi > reference distance Dref + hysteresis distance Dhys" is detected while in "holographic small font display mode", the system switches to "simple large font display mode". To avoid display mode jitter caused by the target object being near a threshold during power-on initialization, the system can initially display according to the previously saved display mode or the preset default mode after power-on, and then execute the screen switching control according to the switching rules.

[0054] The technical solution of this disclosure embodiment displays a device that, after power-on, starts a timer and continuously detects whether a target object exists in front of the device. If a target object is detected, an information display interface switching process is initiated. If no target object is detected within a preset time, a screen saver interface is entered before exiting the interface switching process. The information display interface includes two modes: a "concise large font display mode" that prioritizes key information at long distances, focusing on displaying target temperature, actual temperature, and fault information; and a "holographic small font display mode" that displays more comprehensive information for close-range operation, including process curves, power supply voltage, damper / fan / burner status, stage, running time, and date. The system compares the human-machine first distance information Dmmi obtained from distance measurement with the reference distance Dref, and introduces a hysteresis distance Dhys to form upper and lower thresholds, avoiding back-and-forth switching near the thresholds. Through hysteresis control of the reference distance plus the hysteresis distance, the interface remains stable when the target object moves near the threshold, reducing screen power consumption and aging, while also reducing false triggering and invalid display.

[0055] Example 3 Figure 8 This is a schematic diagram of the structure of a display interface switching device for a display device provided in an embodiment of this disclosure, as shown below. Figure 8 As shown, the device includes: a first distance information receiving module 210, a first screen information display module 220, an interface switching control signal sending module 230, and a screen information switching module 340.

[0056] A first distance information receiving module is used to receive first distance information between the target object and the display device; a first screen information display module is used to continue displaying first screen information on the display device when the first distance information and a first preset distance threshold meet a first condition; an interface switching control signal sending module is used to generate a switching display screen processing result and send the interface switching control signal to the controller when the first distance information and the second preset distance threshold meet a second condition; a screen information switching module is used to control the display device to switch from first screen information to second screen information based on the controller; wherein, both the first screen information and the second screen information display the environmental information of the tobacco curing room, and the display size of the environmental information is different.

[0057] The technical solution of this disclosure embodiment involves a display device deployed at a preset location in a tobacco curing barn. The display device integrates a processor and a controller. Based on the processor's processing results, an interface switching control signal is sent to the controller, causing the controller to perform a display interface switching operation. The processor determines the processing result using the following method: First, it receives first distance information between the target object and the display device. Then, when the first distance information and a first preset distance threshold satisfy a first condition, the display device continues to display first screen information. Further, when the first distance information and the second preset distance threshold satisfy a second condition, a processing result for switching the display screen is generated, and an interface switching control signal is sent to the controller. Finally, the controller controls the display device to switch from the first screen information to the second screen information. Both the first and second screen information display environmental information from the tobacco curing barn, and the display sizes of the environmental information differ. This solves the problem in existing technologies where elderly people must stand in front of the display device to see the data on the screen, resulting in low operational efficiency and a poor user experience. This disclosure implements a threshold condition-controlled switching logic to control the screen information of the display device, thereby achieving automatic switching of the display interface. This effectively reduces display jitter caused by frequent switching, thereby improving display stability, user experience, and the intelligence and convenience of interaction.

[0058] Based on the above technical solutions, when the first distance information is greater than the first preset distance threshold, the first preset distance threshold is greater than the second preset distance threshold; when the first distance information is close to the display device, the first preset distance threshold is less than the second preset distance threshold, wherein the close proximity is used to reflect that the first distance information between the target object and the display device is less than the first preset distance threshold.

[0059] Based on the above technical solutions, if the first distance information is greater than the first preset distance threshold and the first distance information is greater than the second preset distance threshold during continuous movement, then the first screen information associated with the first preset distance threshold will continue to be displayed.

[0060] Based on the above technical solutions, during the movement, if the first distance information is less than or equal to the second preset distance threshold, a processing result for switching the display screen is generated to display the second screen information, wherein the second screen information is related to the screen associated with the second preset distance threshold.

[0061] Based on the above technical solutions, when the first distance information is close to the display device, if the first distance information is less than the first preset distance threshold and continues to be less than the second preset distance threshold during the movement, then the first screen information will continue to be displayed, wherein the first screen information is related to the screen associated with the first preset distance threshold.

[0062] Based on the above technical solutions, during the movement, if the first distance information is greater than or equal to the second preset distance threshold, a processing result for switching the display screen is generated to display the second screen information, wherein the second screen information is related to the screen associated with the second preset distance threshold.

[0063] Based on the above technical solutions, the content of the first screen information includes at least one or more of the following: target temperature, actual temperature, and fault information.

[0064] Based on the above technical solutions, the content of the second screen information includes at least one or more of the following: target temperature, actual temperature, fault information, baking process curve, power supply voltage, cold air damper status, circulating fan status, burner status, baking stage, running time, and date.

[0065] Based on the above technical solutions, the device further includes: a screen-off processing module, used to turn off the screen if the first distance information of the target object is not received within a preset time period.
