Detailed Description
The utility model is further illustrated by the following examples, which are not intended to limit the scope of the utility model.
Fig. 1 is a flowchart of a light sensation control method for an intelligent household appliance according to an exemplary embodiment of the present invention, where the light sensation control method is applied to an intelligent household appliance, the intelligent household appliance includes an operation panel and photosensitive assemblies disposed around the operation panel, the number of the photosensitive assemblies may be 1, or may be multiple, and the number of the photosensitive assemblies in the embodiment of the present invention is not particularly limited. Referring to fig. 1, the method comprises the steps of:
Wherein the photoelectric signal is indicative of ambient brightness. The photoelectric signal can be a photoelectric voltage signal or a photocurrent signal, and in the embodiment, the photoelectric signal is taken as the photoelectric voltage signal as an example to introduce the light sensing control process of the intelligent household appliance.
In one embodiment, the infrared sensor is disposed on or near the operation panel, and the infrared sensor detects whether the operation panel is blocked by the blocking object.
In one embodiment, the ultrasonic sensor is disposed on or near the operation panel, and the ultrasonic sensor detects whether the operation panel is blocked by a blocking object.
In one embodiment, a camera is arranged at the accessory of the operation panel or on the operation panel, and whether the operation panel is blocked by a blocking object is determined by carrying out image recognition on an image shot by the camera.
The operation panel is shielded by a shielding object, and may be in the following scene: the user waves hands, wipes the operation panel, passes by from the front of the operation panel and the like aiming at the gesture function of the intelligent household appliance. Because the photosensitive assembly is arranged on or near the operation panel, the scene can shield the photosensitive assembly, so that the amplitude of a photoelectric signal acquired by the photosensitive assembly is reduced, the photoelectric signal fluctuates, and the fluctuation needs to be eliminated.
In one embodiment, the photosensitive assembly comprises an ambient light sensor for collecting visible light recognizable by human eyes, the wavelength range of the visible light is 400 nm-780 nm, and the detection range of the ambient light sensor is selected to be close to the wavelength range of visual sensing, so that the effective detection wave band is limited in the range of the visible light wave band, and the influence of the gesture infrared emission tube and invisible light wave bands in the environment on the photoelectric signals is eliminated.
Because the time length of the user waving or wiping the operation panel or passing the operation panel is not too long, in the embodiment of the utility model, under the condition that the operation panel is determined to be shielded by the shielding object, the photoelectric signal acquired by the photosensitive component is sampled in the target sampling period which is longer than the shielding time length of the operation panel shielded by the shielding object, so that the intelligent household appliance is subjected to light sensation control according to the sampling data acquired by the target sampling period.
In one embodiment, the occlusion duration is determined from historical occlusion data of the occlusion operating panel by the occlusion, the historical occlusion data comprising at least one of: historical shielding duration and historical moving speed of the shielding object in the process of shielding the operation panel. The historical blocking duration and the historical moving speed can be obtained by fitting or machine learning historical blocking data when the user operates the operation panel historically.
And if the historical occlusion data comprises the historical occlusion duration, directly setting the target sampling period to be larger than the historical occlusion duration.
If the historical shielding data comprises the historical moving speed of the shielding object in the process of shielding the operation panel, determining the historical shielding duration according to the historical moving speed, and setting the target sampling period to be larger than the historical shielding duration. One implementation of determining the historical occlusion duration based on the historical movement speed is described as follows:
the intelligent household electrical appliances that possess the gesture function can set up two light sense windows on its operating panel, and two light sense windows set up about or about. The distance S between the two light sensing windows is fixed, and when the first light sensing window detects a gesture and the second light sensing window also detects the gesture within the time duration t, the smart appliance executes an action corresponding to the gesture, such as starting or closing. When the first light sensing window detects a gesture and the second light sensing window does not detect the gesture within the time length t, the intelligent household appliance determines that the gesture is invalid. According to the distance S and the duration t, the slowest speed of the gesture of the user is represented as V ═ S/t, the time at which the gesture of the user passes through the light sensing window is t ═ 10cm/V, namely the shielding duration, wherein 10cm is the width of the shadow formed by the width of the hand of the user on the operation panel.
For different shelters, the sheltering durations of the different shelters are different, for example, the sheltering duration of the user for controlling the intelligent household appliance through the gesture function is generally smaller than the sheltering duration of the user for wiping the operation panel. The corresponding relation between the shielding object type and the shielding duration can be obtained by fitting or machine learning historical shielding data in advance. The shade class may be, for example, palm, rag, torso, etc.
And 102, carrying out light sensing control on the intelligent household appliance according to the sampling data obtained by sampling the photoelectric signal for many times.
Wherein, the sampling number of times of sampling data can set up by oneself according to actual demand, for example, carry out 5 samplings to the photoelectric signal to according to the sampling data that 5 samplings obtained, carry out light sense control to intelligent household electrical appliances.
In one embodiment, when the light sensing control is performed, the maximum value and the minimum value in the sampled data sampled for multiple times are removed, the average value of the sampled data after the maximum value and the minimum value are removed is calculated, and the light sensing control is performed on the intelligent household appliance according to the average value. Under the condition that the operation panel is shielded by a shielding object, the sampling period is adjusted, so that only a small amount of shielded sampling data are obtained from sampling data obtained by multiple times, the shielded sampling data (fluctuation data) can be filtered after the maximum value and the minimum value in the sampling data are removed, and light sensation control is performed according to photoelectric signals sampled under the condition that the sampling data are not shielded, so that the accuracy of the light sensation control of the intelligent household appliance is improved.
The sudden change of the photoelectric signals collected by the photosensitive components can also be caused by the opening or closing of the indoor illuminating lamps and the pulling up or pulling away of the curtain. In one embodiment, when the intelligent household appliance is subjected to light sensation control, a difference value of sampling data sampled at two adjacent times is calculated, if the difference value is greater than a difference threshold value, it is indicated that the ambient brightness has sudden change, which is probably caused by the opening or closing of an indoor illuminating lamp or the pulling up or pulling back of a curtain, under the condition, the photoelectric signal is re-sampled after delaying for a preset time period, and the light sensation control is performed on the intelligent household appliance according to the sampling data obtained by re-sampling. According to the sampled data obtained by resampling, when the intelligent household appliance is subjected to light sensing control, the average value of the sampled data obtained by resampling can be obtained, and the intelligent household appliance is subjected to light sensing control according to the average value.
The number of resampling times may be set according to actual conditions, and may be the same as or different from the sampling times in step 101. The difference threshold value can be set according to the actual situation, for example, set to be half of the amplitude of the photoelectric signal collected when the photosensitive component is shielded. The preset time period may be determined according to an operation time period for a user to perform a lamp turning on and off or a curtain pulling motion.
In one embodiment, when the intelligent household appliance is subjected to light sensation control, a difference value of sampling data sampled twice in adjacent two times is calculated, if the number of target difference values is smaller than a number threshold value, the sampling at the stage is indicated, the change of the sampling data is small, the fluctuation of photoelectric signals is small, an average value of the sampling data sampled for multiple times is calculated according to the sampling data sampled for multiple times, and the intelligent household appliance is subjected to light sensation control according to the average value, wherein the target difference value is a difference value which is larger than the difference threshold value in the calculated difference value. If the number of the target difference values is larger than or equal to the number threshold, the sampling at the stage is described, the change of the sampling data is large, the fluctuation of the photoelectric signal is large, the light sensation control is not performed on the intelligent household appliance according to the sampling data at the stage, the sampling data at the previous stage is used, and the light sensation control action on the intelligent household appliance is not performed.
For example, suppose co-samplingSample data of S times and S times is represented as A1、A2、…、AsThe difference of the sampled data is expressed as Δ A1＝A2-A1，ΔA2＝A3-A2，…，ΔAs-1＝As-As-1If Δ A1～ΔAs-1In all of M, all of the M are greater than the difference threshold value Delta AmaxIf the sampled data is deemed invalid, the light sensing control action on the intelligent household appliance is not executed. If Δ A1～ΔAs-1All or most of them are less than or equal to the difference threshold value Delta AmaxIf the change of the sampling data is small and the fluctuation of the photoelectric signal is small, the intelligent household appliance is subjected to light sensing control according to the sampling data sampled for multiple times.
Photoelectric signal that photosensitive assembly gathered is come by photoelectric signal conversion, and photoelectric signal is comparatively sensitive to the temperature, and the reason such as open because of the top of a kitchen range can make ambient temperature rise, causes photoelectric signal's amplitude increase, and the change that also is ambient temperature can lead to photoelectric signal's fluctuation, and then leads to photoelectric signal's fluctuation.
In one embodiment, the optoelectronic signal is also temperature compensated. When temperature compensation is carried out, the current temperature sampled by the temperature sensor is obtained, the temperature sensor is arranged close to the photosensitive assembly, the brightness compensation value corresponding to the current temperature is determined according to the corresponding relation between the temperature and the brightness compensation value, temperature compensation is carried out on the sampled data according to the determined brightness compensation value, and in step 102, light sensation control is carried out on the intelligent household appliance according to the sampled data subjected to temperature compensation.
The corresponding relationship between the temperature and the brightness compensation value can be determined in advance according to experimental data. The corresponding relationship between the temperature and the brightness compensation value is shown in the form of a table below.
The compensation coefficients a1, a2 and a3 are determined experimentally.
The formula for temperature compensation is shown below:
AD1＝AD+△AD；
where AD1 denotes sample data after temperature compensation, AD denotes sample data without temperature compensation, and Δ AD denotes a luminance compensation value.
In the table, with 25 ℃ as a reference point, when the ambient temperature is less than 25 ℃, the sampled data is subjected to positive compensation, and when the ambient temperature is greater than 25 ℃, the sampled data is subjected to negative compensation. When the temperature exceeds 45 deg.c, the maximum compensation value is defined. The compensation coefficients a1, a2 and a3 have different values in different temperature ranges.
It should be noted that, the correspondence between the temperature and the brightness compensation value is not limited to be shown in the form of a table, and may also be shown in the form of a function, which is not particularly limited in the embodiment of the present invention.
