Description

Technical Field

[0001] The invention belongs to the field of intelligent control of equipment, and in particular relates to an intelligent control system for simulated flames of an electric fireplace. Background Art

[0002] With the improvement of living standards and changes in aesthetic standards, people are increasingly demanding more decorative and beautifying indoor environments. Electric fireplaces, as a home product that combines both decorative and heating functions, are gaining popularity. Simulated flames, a core element of electric fireplaces, have a direct impact on their overall aesthetics and user experience, thanks to their fidelity and dynamic effects. However, traditional simulated flame control systems cannot meet this growing demand.

[0003] The traditional electric fireplace simulated flame control system has the following problems: First, the traditional electric fireplace simulated flame control system cannot automatically adjust the power level of the simulated flame, which may cause the simulated flame to maintain the same power for a long time, resulting in serious power loss.

[0004] Second, the traditional electric fireplace simulated flame control system has a relatively simple analysis of the color of the simulated flame. It only determines the color of the simulated flame based on current environmental factors, does not consider the historical usage of various simulated flame colors, cannot comprehensively consider user preferences, and has low intelligence.

[0005] Third, the traditional electric fireplace simulated flame control system has a simple analysis of the brightness of the simulated flame color. It only analyzes the brightness of the simulated flame color based on the current light brightness, does not consider the user's preferred brightness, and does not make corrections to it. The adjustment accuracy of the simulated flame color brightness is low, resulting in the simulated flame color brightness not meeting user expectations.

[0006] Fourth, the traditional electric fireplace simulation flame control system has a relatively fixed playback of the animation corresponding to the simulation flame color, and does not adjust the playback animation corresponding to the simulation flame color, which reduces the overall visual effect. Summary of the Invention

The correction value of the required brightness of the current simulated flame color is compared with the preset reference correction value of the required brightness of the current simulated flame color. If the correction value of the required brightness of the current simulated flame color is less than or equal to the preset reference correction value of the required brightness of the current simulated flame color, it indicates that the required brightness of the current simulated flame color does not need to be corrected; otherwise, it indicates that the required brightness of the current simulated flame color needs to be corrected, and the corrected required brightness of the simulated flame color is E″+E″′.

[0021] According to the average value of the height of the flame area in each image of the playback animation corresponding to the simulated flame color, each flame area in each image of the playback animation corresponding to the simulated flame color is classified into a category, and the height of each flame area in each image of the playback animation corresponding to the simulated flame color is compared with the average value of the height of the flame area in the corresponding image. If the height of a flame area in a certain image of the playback animation corresponding to the simulated flame color is greater than or equal to the average value of the height of the flame area in the corresponding image, then the flame area in the image of the playback animation corresponding to the simulated flame color is classified as a priority adjustment category; otherwise, the flame area in the image of the playback animation corresponding to the simulated flame color is classified as a secondary adjustment category. The flame areas of the priority adjustment category and the flame areas of the secondary adjustment category of each image in the playback animation corresponding to the current simulated flame color are counted, and then the flame areas of the priority adjustment category and the flame areas of the secondary adjustment category in the playback animation corresponding to the current simulated flame color are screened.

[0035] The connection relationship between modules refers to Figure 1 .

[0036] The environmental data acquisition module is used to collect the current indoor temperature, humidity and light brightness.

[0037] The simulated flame color acquisition module is used to compare the current indoor temperature, humidity and light brightness with the temperature, humidity and light brightness corresponding to each simulated flame color to obtain the matching degree of each simulated flame color and obtain the current simulated flame color.

[0038] The current simulated flame color is obtained as follows: the temperature and humidity sensors are used to collect the current indoor temperature and humidity, which are recorded as T and B respectively. The light sensor is used to collect the current indoor light brightness, which is recorded as D. The temperature, humidity and light brightness corresponding to each simulated flame color are extracted from the database and recorded as T respectively. i 、B i and D i , i represents the number of the i-th simulated flame color, i=1,2,...,j, compare the current indoor temperature, humidity and light brightness with the temperature, humidity and light brightness corresponding to each simulated flame color, and use the formula Get the color matching degree α of each simulated flame i , ΔT represents the temperature deviation value corresponding to the preset simulated flame color, ΔB represents the humidity deviation value corresponding to the preset simulated flame color, ΔD represents the light brightness deviation value corresponding to the preset simulated flame color, and e represents a natural constant. The matching degree of each simulated flame color is screened, and the simulated flame color with the largest simulated flame color matching degree is set as the current simulated flame color.

[0039] The simulated flame color analysis module is used to obtain the number of times various simulated flame colors appear in history from historical records, obtain the weights of various simulated flame colors in history, analyze the current simulated flame color and the weights of various simulated flame colors in history, obtain the current simulated flame color recommendation, and issue a reminder to the user.

[0040] The current simulation flame color recommendation is analyzed as follows: the number of times each simulation flame color appears in the history is obtained from the historical records, and recorded as f i , through the formula Get the weight β of various historical simulated flame colors i , according to the current simulated flame color, the weight of the current simulated flame color is screened out, and the weight of the current simulated flame color is compared with the preset reference weight of the simulated flame color. If the weight of the historical simulated flame color corresponding to the current simulated flame color is greater than or equal to the preset reference weight of the simulated flame color, it indicates that the current simulated flame color is recommended. Otherwise, it indicates that the current simulated flame color is not recommended, and a reminder is issued to the user.

[0041] It should be supplemented that the present invention comprehensively considers the historical usage of simulated flame colors and current environmental factors to derive the color of the simulated flame, which has a high degree of intelligence and improves user satisfaction.

[0042] The simulated flame brightness analysis module is used to obtain the standard brightness corresponding to the current simulated flame color, obtain the current simulated flame color adjustment brightness according to the current indoor light brightness, comprehensively obtain the current simulated flame color required brightness, and extract the brightness of each use of the current simulated flame color from the historical records, and then correct and adjust the current simulated flame color required brightness.

[0043] The method for obtaining the required brightness of the current simulated flame color is as follows: obtain the standard brightness corresponding to the current simulated flame color, record it as E0, and use the formula The current simulated flame color adjustment brightness E1 is obtained, where ΔD represents the preset unit light brightness, and E′ represents the simulated flame color brightness change corresponding to the preset unit light brightness. The sum of the standard brightness corresponding to the current simulated flame color and the current simulated flame color adjustment brightness is taken as the current simulated flame color required brightness, which is recorded as E″.

[0044] Furthermore, the required brightness of the current simulated flame color is corrected and adjusted. The specific analysis is as follows: the brightness of each use of the current simulated flame color is obtained from the historical records and recorded as G m , m represents the number of the mth brightness used in the current simulated flame color, m=1,2,...,n, through the formula A correction value E″′ of the required brightness of the current simulated flame color is obtained, where n represents the number of times the current simulated flame color is used, and E2 represents the preset reference correction brightness of the current simulated flame color. The correction value of the required brightness of the current simulated flame color is compared with the preset reference correction value of the required brightness of the current simulated flame color. If the correction value of the required brightness of the current simulated flame color is less than or equal to the preset reference correction value of the required brightness of the current simulated flame color, it indicates that the required brightness of the current simulated flame color does not need to be corrected; otherwise, it indicates that the required brightness of the current simulated flame color needs to be corrected, and the corrected required brightness of the simulated flame color is E″+E″′.

[0045] It should be noted that the present invention comprehensively analyzes the brightness of the simulated flame color preferred by the user and adjusts the brightness of the current simulated flame color, so that the brightness adjustment accuracy of the simulated flame color is higher, meeting the user's expectations.

[0046] The simulated flame playback animation analysis module is used to obtain the indoor wind speed and temperature in real time during the operation of the electric fireplace, obtain the playback animation corresponding to the current simulated flame color, classify the flame areas in the playback animation corresponding to the obtained simulated flame color, and then obtain the real-time change in the height of each flame area in the playback animation corresponding to the current simulated flame color based on the real-time change in the indoor temperature.

[0047] The method for obtaining the playback animation corresponding to the current simulated flame color is as follows: the current real-time wind speed in the room is obtained through the wind speed sensor, the simulated flame playback animation of the electric fireplace under various wind speed levels is extracted from the database, the corresponding wind speed level is obtained through the current real-time wind speed in the room, and the playback animation corresponding to the current simulated flame color is filtered out according to the obtained wind speed level.

[0048] Furthermore, the classification of each flame area in the animation corresponding to the current simulated flame color is specifically analyzed as follows: each image of the animation corresponding to the current simulated flame color is obtained through image acquisition technology, each image of the animation corresponding to the simulated flame color is divided into each flame area according to the flame cluster, the contour image of each flame area in each image of the animation corresponding to the simulated flame color is obtained, and the height of each flame area in each image of the animation corresponding to the simulated flame color is obtained, which is recorded as H jr , j represents the number of the jth image of the animation corresponding to the simulated flame color, j = 1, 2, ..., k, r represents the number of the rth flame area, r = 1, 2, ..., s, through the formula Get the average value of the flame area height in each image of the animation corresponding to the simulated flame color s is the number of flame areas.

[0049] According to the average value of the height of the flame area in each image of the playback animation corresponding to the simulated flame color, each flame area in each image of the playback animation corresponding to the simulated flame color is classified into a category, and the height of each flame area in each image of the playback animation corresponding to the simulated flame color is compared with the average value of the height of the flame area in the corresponding image. If the height of a flame area in a certain image of the playback animation corresponding to the simulated flame color is greater than or equal to the average value of the height of the flame area in the corresponding image, then the flame area in the image of the playback animation corresponding to the simulated flame color is classified as a priority adjustment category; otherwise, the flame area in the image of the playback animation corresponding to the simulated flame color is classified as a secondary adjustment category. The flame areas of the priority adjustment category and the flame areas of the secondary adjustment category of each image in the playback animation corresponding to the current simulated flame color are counted, and then the flame areas of the priority adjustment category and the flame areas of the secondary adjustment category in the playback animation corresponding to the current simulated flame color are screened.

[0050] It should be noted that the method for obtaining each flame area of ​​the priority adjustment category and each flame area of ​​the secondary adjustment category is: the number of a certain flame area is screened out from each image in the animation played corresponding to the current simulated flame color, the number of priority adjustment categories and secondary adjustment categories in which the flame area is located is counted, and the number of priority adjustment categories in which the flame area is located is compared with the number of secondary adjustment categories. If the number of priority adjustment categories in which the flame area is located is greater than or equal to the number of secondary adjustment categories, it is classified as the priority adjustment category; otherwise, it is classified as the secondary adjustment category.

[0051] The real-time changes in the height of each flame area in the animation corresponding to the current simulated flame color are specifically analyzed as follows: the indoor temperature at the current time point is collected by the temperature and humidity sensor, which is recorded as t, and the indoor temperature at the previous time point is retrieved from the temperature and humidity sensor, which is recorded as t0. The temperature difference Δt′ between the current time point and the previous time point is obtained by the formula Δt′=t-t0.

[0052] Compare the temperature difference between the current time point and the previous time point with the preset indoor temperature reference difference. If the temperature difference between the current time point and the previous time point is less than or equal to the preset indoor temperature reference difference, the current time point will keep the animation corresponding to the simulated flame color of the previous time point. Otherwise, analyze the adjustment height of each flame area of ​​the priority adjustment category in the animation corresponding to the current simulated flame color. o represents the adjustment height of the oth flame area in the priority adjustment category in the playback animation corresponding to the current simulated flame color, o=1,2,...,q, Δt represents the preset unit temperature, H′ represents the height change of the playback animation corresponding to the simulated flame color corresponding to the preset unit temperature, H o ″′ represents the height of each flame area of ​​the priority adjustment category in the playback animation corresponding to the simulated flame color corresponding to the indoor temperature at the previous preset time point, and then the flame area in the playback animation image corresponding to the simulated flame color of the priority adjustment category is adjusted, and at the same time, the flame area in the playback animation image corresponding to the simulated flame color of the secondary adjustment category is adjusted.

[0053] It should be noted that the current simulated flame color corresponds to the adjustment height of each flame area of ​​the secondary adjustment category in the animation. u represents the height of the u-th flame area of ​​the secondary adjustment category in the animation corresponding to the current simulated flame color, u=1,2,...,v,H u"' represents the height of each flame area of ​​the secondary adjustment category in the animation played corresponding to the simulated flame color corresponding to the indoor temperature at the previous preset time point, and the average of the adjustment heights of each flame area of ​​the secondary adjustment category in the animation played corresponding to the current simulated flame color is calculated. According to the calculated average of the adjustment heights of each flame area of ​​the secondary adjustment category in the animation played corresponding to the current simulated flame color, each flame area of ​​the secondary adjustment category in the animation played corresponding to the current simulated flame color is adjusted.

[0054] It should be noted that the present invention analyzes the playback animation corresponding to the simulated flame color, divides the playback animation corresponding to the simulated flame color into flame areas, classifies the flame areas, and adjusts the height in turn according to different categories, thereby improving the accuracy of the adjustment and enhancing the user's visual experience.

[0055] The simulated flame power real-time analysis module is used to use infrared sensing technology to obtain the outlines of surrounding people and the distance between the surrounding people and the electric fireplace in real time, and accordingly perform real-time analysis on the power of the simulated flame and then adjust the power of the simulated flame.

[0056] The power analysis of the simulated flame is as follows: the outline of the surrounding personnel and the distance between the surrounding personnel and the electric fireplace are obtained in real time through infrared sensing technology. The distance between the surrounding personnel and the electric fireplace is recorded as h. The outline of the personnel corresponding to the resting posture of the personnel is extracted from the database. The obtained outline of the surrounding personnel is compared with the outline of the personnel corresponding to the resting posture of the personnel to obtain the conformity of the personnel posture, which is recorded as φ. Get the power adjustment coefficient of the current simulated flame h0 represents the preset reference distance between the surrounding people and the electric fireplace.

[0057] Furthermore, the power analysis of the simulated flame also includes: Obtain the regulated power P of the current simulated flame, extract the simulated flame power range corresponding to each power level from the database, compare the regulated power of the current simulated flame with the simulated flame power range corresponding to each power level, screen out the power level corresponding to the regulated power of the current simulated flame, compare the power level corresponding to the regulated power of the current simulated flame with the power level of the current simulated flame, if the power level corresponding to the regulated power of the current simulated flame is equal to the power level of the current simulated flame, it indicates that the power of the current simulated flame does not need to be adjusted, otherwise it indicates that the power level of the current simulated flame needs to be adjusted to the power level corresponding to the regulated power of the current simulated flame.

[0058] It should be noted that the present invention analyzes the outlines of surrounding people and the distance between the surrounding people and the electric fireplace to obtain the current simulated flame adjustment power, and adjusts the simulated flame power according to the current simulated flame adjustment power, thereby saving electricity consumption.

[0059] The database is used to store the temperature, humidity and light brightness corresponding to each simulated flame color, the simulated flame playback animation of the electric fireplace under various wind speed levels, the person outline corresponding to the person's resting posture, and the power level corresponding to the simulated flame power.
