Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present invention.

[0021] Embodiment 1, as Figure 1 As shown, the embodiment of the present invention provides a method for optimizing content display of a digital photo frame, which specifically includes the following steps: S100: Acquire operating frequency parameters of a plurality of smart homes, perform user state analysis according to the operating frequency parameters, and obtain a user state coefficient.

[0022] Furthermore, step S100 of the present invention further includes: S110: monitoring the number of working state switching of the plurality of smart homes within a recent preset time interval through the Internet of Things, and summing up the number of working state switching times.

[0023] Specifically, the number of working state switching of multiple smart home devices (such as lamps, automatic curtains, etc.) within a preset time interval is monitored through the Internet of Things, such as the number of times the lights are turned on and off or the brightness of the lamps is adjusted. For example, the working state of the device (such as on / off) is monitored in real time using circuit sensors, and the timestamp of the state change is recorded. The preset time interval can be set according to the actual scenario, such as the last 30 minutes, the last hour, etc., to obtain the number of working state switching of multiple smart homes, and add and sum the number of state switching of multiple homes, and use the sum as the number of working state switching. By obtaining the number of working state switching, a basis is provided for subsequent user state analysis.

[0024] S120: Calculate and obtain an operating frequency parameter according to the number of operating state switching times and a preset time interval.

[0025] Furthermore, step S120 of the present invention further includes: S121: Calculate the ratio of the working state switching times to the preset time interval to obtain the working state switching times per unit time as a working frequency parameter.

[0026] Specifically, the ratio of the working state switching times and the preset time interval is calculated to obtain the working state switching times per unit time, and set it as the working frequency parameter; for example, assuming that the working state switching times within the preset time interval is 9, and the preset time interval is 30 minutes, the working frequency parameter is 9 / 30, which is equal to 0.3 times / minute.

[0027] S130: Perform user state analysis according to the operating frequency parameters to obtain a user state coefficient.

[0028] Furthermore, step S130 of the present invention further includes: S131: Obtain an average operating frequency parameter of a user using a smart home in a historical period; S132: Calculate a ratio of the operating frequency parameter to the average operating frequency parameter to obtain a user state coefficient.

[0029] Specifically, first, the average working frequency parameter of the user's use of the smart home in the historical time (such as the last month) is obtained, that is, the state switching data of the smart home device in a period of time is collected and recorded, including the timestamp of each switch; then for each device, the total number of switches in the historical time is calculated, and the total number of switches is divided by the total time interval to obtain the historical average working frequency parameter of the device. The ratio of the working frequency parameter and the average working frequency parameter is further calculated, and the ratio is set as the user state coefficient, wherein the user state coefficient is greater than 1, indicating that the current user's activity frequency is higher than the average level, and the user may be busy; if the user state coefficient is less than 1, it means that the user may be in a leisure state; the larger the working frequency parameter, the larger the user state coefficient, indicating that the user is busier, at this time the user pays more attention to the prompt content (such as weather, schedule) of the digital photo frame, and pays less attention to the image content (photos), so the digital photo frame should update the prompt content (such as weather, schedule reminders) more frequently. The smaller the working frequency parameter is, the smaller the user state coefficient is, and the more casual the user is. At this time, the user pays more attention to the image content (photos) and less attention to the prompt content (such as weather and time). Therefore, the digital photo frame should update the image content (photos) more frequently.

[0030] S200: Allocate prompt weight and image weight according to the user state coefficient.

[0031] Furthermore, step S200 of the present invention further includes: S210: Obtaining a preset prompt weight and a preset image weight, wherein the sum of the preset prompt weight and the preset image weight is 1; S220: Multiplying the user state coefficient by the preset prompt weight to obtain a prompt weight; S230: Calculating an image weight based on the prompt weight.

[0032] Specifically, a preset prompt weight and a preset image weight are obtained, and the sum of the preset prompt weight and the preset image weight is 1. The user can configure the preset prompt weight and the preset image weight according to actual needs. For example, if the user pays more attention to the prompt content (such as weather and schedule reminders), the preset prompt weight is larger; if the user pays more attention to the image content (photos), the preset image weight is larger; for example, the user can set the preset prompt weight and the preset image weight to 0.5 respectively, which means that when the user status is unknown, the importance of the prompt content and the image content is equal.

[0033] Next, the user status coefficient is multiplied by the preset prompt weight to obtain the updated prompt weight. For example, assuming that the user status coefficient is 1.4 and the preset prompt weight is 0.5, the updated prompt weight is 0.7, indicating that the user pays more attention to the prompt content (such as weather and schedule reminders) in the current state. Then, 1 is subtracted from the updated prompt weight to obtain the updated image weight. For example, assuming that the updated prompt weight is 0.7, the updated image weight is 1 minus 0.7, which equals 0.3. By configuring the prompt weight and image weight according to the user's current state, the digital photo frame can dynamically adjust the content attention according to the user's current state to better meet the user's needs.

[0034] S300: Optimizing the content display of the digital photo frame according to the prompt weight and the image weight, obtaining optimal display parameters including optimal image content switching frequency and optimal prompt content update frequency, and performing content display, wherein the optimization includes calculating a display score according to the image content switching frequency, the prompt content update frequency and the pixel refresh rate.

[0035] Furthermore, step S300 of the present invention further includes: S310: Constructing a content display optimization function according to the prompt weight and the image weight, as shown in the following formula: ;in, To rate the display, and are the prompt weight and image weight, To indicate the frequency of content updates, To set the frequency of updating the preset reminder content, Switching frequency for image content, To preset the switching frequency of the image content, is the preset pixel refresh rate of the digital photo frame. The pixel refresh rate being optimized.

[0036] Specifically, in the content display optimization function, To score the display, the larger the display score, the better the display effect; and are the prompt weight and image weight; To indicate the frequency of content updates, The preset prompt content update frequency is a standard prompt content update frequency set according to user needs, such as 20 seconds / time; Switching frequency for image content, is a preset image content switching frequency, which is a standard image content updating frequency set according to user needs, such as 30 seconds / time; is the preset pixel refresh rate (standard pixel refresh rate) of the digital photo frame. To optimize the pixel refresh rate, the pixel refresh rate should be reduced as much as possible to reduce energy consumption and slow down device aging while maintaining a satisfactory content display effect for users.

[0037] By constructing a content display optimization function, the display score can be comprehensively evaluated from three aspects: image content switching frequency, prompt content update frequency and pixel refresh rate, thereby effectively improving the scientificity, rationality and accuracy of the content display score calculation, and providing a reliable basis for optimizing display parameters.

[0038] S320: Optimizing the content display of the digital photo frame according to the content display optimization function, and obtaining the optimal image content switching frequency and the optimal prompt content updating frequency corresponding to the maximum display score as optimal display parameters.

[0039] Further, step S320 of the present invention further includes: S321: Randomly set the first image content switching frequency and the first prompt content updating frequency of the digital photo frame; S322: According to the first image content switching frequency and the first prompt content updating frequency, calculate and obtain the ratio of pixel refreshes in the digital photo frame per second as the first pixel refresh rate; S323: According to the first image content switching frequency, the first prompt content updating frequency and the first pixel refresh rate, based on the content display optimization function, calculate and obtain the first display score.

[0040] Specifically, first, the image content switching frequency threshold and the prompt content update frequency threshold of the digital photo frame are obtained, and the image content switching frequency threshold and the prompt content update frequency threshold can be set according to the equipment production parameters, for example, the image content switching frequency threshold is 3 seconds / time to 100 seconds / time; and any image content switching frequency and any prompt content update frequency are randomly selected within the image content switching frequency threshold and the prompt content update frequency threshold to obtain the first image content switching frequency and the first prompt content update frequency.

[0041] Next, the proportion of pixel refreshes in the digital photo frame per second is calculated based on the first image content switching frequency and the first prompt content update frequency, and the proportion is set as the first pixel refresh rate. For example, the proportion of the image content display area in the digital photo frame is 90%, the proportion of the prompt content display area is 10%, and the first image content switching frequency and the first prompt content update frequency are both 5 seconds / time. Then, the proportion of pixel refreshes in the digital photo frame per second is 0.9 / 5+0.1 / 5, which is equal to 0.2, that is, the first pixel refresh rate is 20%. Further, the content display optimization function is used to calculate the first display score of the first display parameter (including the first image content switching frequency and the first prompt content update frequency) based on the first image content switching frequency, the first prompt content update frequency and the first pixel refresh rate.

[0042] S324: Continue to optimize the content display of the digital photo frame, and obtain the optimal image content switching frequency and the optimal prompt content updating frequency corresponding to the maximum display score as optimal display parameters.

[0043] Further, step S324 of the present invention further includes: S3241: Continue to randomly set the image content switching frequency and the prompt content updating frequency, and calculate the display score; S3242: Until the optimization converges, output the optimal image content switching frequency and the optimal prompt content updating frequency corresponding to the maximum display score as the optimal display parameters.

[0044] Specifically, using the same method, the second image content switching frequency and the second prompt content update frequency are continuously randomly selected within the image content switching frequency threshold and the prompt content update frequency threshold of the digital photo frame, and the second pixel refresh rate is calculated; then based on the content display optimization function, the second display score of the second display parameter (including the second image content switching frequency and the second prompt content update frequency) is calculated according to the second image content switching frequency, the second prompt content update frequency and the second pixel refresh rate. Then, using the same method, the iterative random selection of display parameters and the display score calculation are continued until a predetermined number of convergences is reached. The predetermined number of convergences is the number of random selections of parameters, which can be set according to the optimization requirements. The higher the optimization accuracy requirements, the greater the predetermined number of convergences. When the predetermined number of convergences is reached, the optimization converges, and multiple display parameters and multiple display scores are obtained at this time, and the display parameters corresponding to the maximum display score are output as the optimal display parameters, and the optimal display parameters include the optimal image content switching frequency and the optimal prompt content update frequency.

[0045] Finally, the digital photo frame is controlled to display content according to the optimal image content switching frequency and the optimal prompt content updating frequency.
