Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Fig. 1 is a flowchart of a light sensation control method of an intelligent home appliance according to an exemplary embodiment of the present invention, where the light sensation control method is applied to an intelligent home appliance, and the intelligent home appliance includes an operation panel and a photosensitive assembly, where the photosensitive assembly is disposed on or near the operation panel, and the number of photosensitive assemblies may be 1 or more. Referring to fig. 1, the method comprises the steps of:
Wherein the optoelectronic signal characterizes an ambient brightness. The photoelectric signal can be a photovoltage signal or a photocurrent signal, and in the embodiment of the invention, the photovoltage signal is taken as an example, and the photoinduction control process of the intelligent household appliance is introduced.
In one embodiment, the infrared sensor is disposed on or near the operation panel, and it is detected whether the operation panel is shielded by a shielding object.
In one embodiment, an ultrasonic sensor is provided on or near the operation panel, and the ultrasonic sensor detects whether or not the operation panel is shielded by a shielding object.
In one embodiment, a camera is arranged on an accessory of the operation panel or is arranged 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, which may be the following scene: the user swings the hand, wipes the operation panel, passes through 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 the photoelectric signal collected by the photosensitive assembly is reduced, and the fluctuation exists in the photoelectric signal, and the fluctuation needs to be eliminated.
In one embodiment, the photosensitive component comprises an ambient light sensor for collecting visible light recognizable by human eyes, the wavelength range of the ambient light sensor is 400 nm-780 nm, and the effective detection band is limited in the visible light band range by selecting the detection range of the ambient light sensor to be close to the wavelength range of visual induction, so that the influence of the gesture infrared transmitting tube and the invisible light band in the environment on the photoelectric signals is eliminated.
Because the time length of the user waving hands or wiping the operation panel or passing before the operation panel is not too long, in the embodiment of the invention, under the condition that the operation panel is determined to be shielded by the shielding object, the photoelectric signals collected by the photosensitive component are sampled with the target sampling period longer than the shielding time length of the operation panel shielded by the shielding object, so that the follow-up sampling data obtained by sampling according to the target sampling period can conveniently carry out light sensation control on the intelligent household appliance.
In one embodiment, the occlusion duration is determined from historical occlusion data of the occlusion operation panel, the historical occlusion data including at least one of: historical shielding duration and historical moving speed of the shielding object in the process of shielding the operation panel. The history shielding time length and the history moving speed can be obtained in advance through fitting or machine learning of history shielding data when the user historically operates the operation panel.
If the historical shielding data comprises the historical shielding duration, the target sampling period is directly set to be larger than the historical shielding duration.
If the historical shielding data comprises the historical moving speed of the shielding object in the shielding operation panel process, 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 a historical occlusion time based on a historical movement speed is described below:
the intelligent household appliance with the gesture function is characterized in that two light-sensing windows are arranged on an operation panel of the intelligent household appliance, and the two light-sensing windows are arranged up and down or left and right. The distance S between the two light-sensing windows is fixed, and when the first light-sensing window detects a gesture and the second window also detects a gesture within the duration t, the smart home appliance performs an action corresponding to the gesture, such as starting or closing. When the first light sensing window detects the gesture, but the second window does not detect the gesture within the time period t, the intelligent household appliance determines that the gesture is invalid. According to the distance S and the duration t, it can be determined that the slowest speed of the gesture of the user is expressed as v=s/t, and the time for the gesture to pass through the light sensing window at the slowest speed is t' =10 cm/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 shielding objects, the shielding time length is different, for example, the shielding time length of a user controlling the intelligent home through a gesture function is generally smaller than the shielding time length of a user wiping an operation panel, in one embodiment, when a target sampling period is set, the type of the shielding object which is currently shielded by the operation panel is determined, the shielding time length corresponding to the type of the shielding object which is currently shielded is determined according to the corresponding relation between the type of the shielding object and the shielding time length, and the target sampling period is set to be larger than the shielding time length of the type of the shielding object which is currently shielded. The corresponding relation between the type of the shielding object and the shielding duration can be obtained in advance through fitting or machine learning of historical shielding data. The shade category may be, for example, palm, rag, torso, etc.
The sampling times of the sampling data can be set according to actual demands, for example, the photoelectric signals are sampled for 5 times, and the intelligent household appliances are subjected to light sensation control according to the sampling data obtained by the 5 times of sampling.
In one embodiment, when the light sensation control is performed, the maximum value and the minimum value in the sampled data of the plurality of times of sampling are removed, an average value of the sampled data after the maximum value and the minimum value are removed is calculated, and the light sensation 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 is in sampling data obtained by sampling for a plurality of times, the shielded sampling data (fluctuation data) can be filtered out after the maximum value and the minimum value in the sampling data are removed, and light sensation control is carried out according to a photoelectric signal sampled under the condition that the sampling is not shielded, so that the accuracy of light sensation control of the intelligent household appliance is improved.
The opening or closing of the indoor lighting lamp and the pulling up or pulling out of the curtain can also cause the abrupt change of the photoelectric signal collected by the photosensitive component. In one embodiment, when the intelligent household appliance is subjected to light sensing control, calculating a difference value of sampling data of two adjacent samples, if the difference value is larger than a difference value threshold value, indicating that the environment brightness is suddenly changed, wherein the environment brightness is likely to be caused by the opening or closing of an indoor illuminating lamp or the pulling up or pulling up of a curtain, under the condition, resampling the photoelectric signal after delaying a preset time period, and performing light sensing control on the intelligent household appliance according to the sampling data obtained by resampling. When the intelligent household appliance is subjected to light sensation control according to the sampling data obtained through resampling, the average value of the sampling data obtained through resampling can be obtained, and the intelligent household appliance is subjected to light sensation control according to the average value.
The number of resampling may be set according to the actual situation, and may be the same as or different from the number of sampling in step 101. The difference threshold can be set according to practical situations, for example, the difference threshold is set to be half of the amplitude of the photoelectric signal acquired when the photosensitive component is shielded. The preset time period may be determined according to an operation time period for a user to make a lamp switching or a window curtain pulling action.
In one embodiment, when the intelligent household appliance is subjected to light sensing control, calculating the difference value of sampling data of two adjacent samples, if the number of target difference values is smaller than a number threshold value, indicating the sampling at the stage, the change of the sampling data is smaller, and the fluctuation of a photoelectric signal is smaller, calculating the average value of the sampling data of multiple samples according to the sampling data of multiple samples, namely, calculating the average value of the sampling data of multiple samples, and performing light sensing control on the intelligent household appliance according to the average value, wherein the target difference value is the difference value larger than the difference value threshold value in the calculated difference values. If the number of the target difference values is greater than or equal to the number threshold value, the sampling at the stage is indicated that the change of the sampling data is large and the fluctuation of the photoelectric signal is large, the intelligent household appliance is not subjected to light sensation control according to the sampling data at the stage, but the sampling data at the previous stage is used along the edge, and the light sensation control action of the intelligent household appliance is not executed.
For example, assume that the samples are taken together S times, the sampled data of which is denoted A 1 、A 2 、…、A s The difference of the sampled data is denoted as deltaa 1 ＝A 2 -A 1 ，ΔA 2 ＝A 3 -A 2 ，…，ΔA s-1 ＝A s -A s-1 If DeltaA 1 ～ΔA s-1 In which M are all greater than the difference threshold DeltaA max The fact that the change of the sampling data is large, fluctuation of the photoelectric signals is large and is probably caused by interference is indicated, and when the sampling data is regarded as invalid, the light sensation control action on the intelligent household appliance is not executed. If delta A 1 ～ΔA s-1 In which all or most of them are less than or equal to the difference threshold DeltaA max The change of the sampling data is smaller, and the fluctuation of the photoelectric signal is smaller, so that the intelligent household appliance is subjected to light sensation control according to the sampling data sampled for multiple times.
Photoelectric signals collected by the photosensitive component are converted from photoelectric signals, the photoelectric signals are sensitive to temperature, the ambient temperature is increased due to the fact that a cooking bench is opened, and the like, so that the amplitude of the photoelectric signals is increased, namely fluctuation of the photoelectric signals is caused by the change of the ambient temperature, and further fluctuation of the photoelectric signals is caused.
In one embodiment, the optical electrical signal is also temperature compensated. When temperature compensation is carried out, the current temperature sampled by a temperature sensor is obtained, the temperature sensor is arranged close to a photosensitive component, the brightness compensation value corresponding to the current temperature is determined according to the corresponding relation between the temperature and the brightness compensation value, the temperature compensation is carried out on sampling data according to the determined brightness compensation value, and in step 102, light sense control is carried out on the intelligent household appliance according to the sampling data subjected to the temperature compensation.
The corresponding relation between the temperature and the brightness compensation value can be determined in advance according to experimental data. The correspondence between the temperature and the brightness compensation value is shown in the form of a table.
Wherein the compensation coefficients a1, a2, a3 are determined experimentally.
The formula for temperature compensation is expressed as follows:
AD1＝AD+△AD；
wherein AD1 represents the sampled data after temperature compensation, AD represents the sampled data without temperature compensation, and Δad represents the brightness compensation value.
In the table, the reference point is 25 ℃, when the ambient temperature is less than 25 ℃, the sampled data is positively compensated, and when the ambient temperature is greater than 25 ℃, the sampled data is negatively compensated. When the temperature exceeds 45 ℃, a maximum compensation value is defined. In different temperature ranges, the compensation coefficients a1, a2 and a3 have different values.
When the temperature and brightness compensation values are to be described, the correspondence relationship between the temperature and brightness compensation values is not limited to be displayed in a table form, but may be displayed in a function form, and the embodiment of the invention is not particularly limited thereto.
In one embodiment, the intelligent home appliance comprises an illuminating lamp, and the light sensation control on the intelligent home appliance comprises light sensation control on the illuminating lamp, namely, when the operation panel is shielded by a shielding object, the brightness of the illuminating lamp is adjusted according to the sampling data obtained by sampling in a target sampling period, and the interference of fluctuation data on the sampling data is eliminated, so that the accuracy of the light sensation control on the illuminating lamp is improved, and the brightness of the illuminating lamp is not suddenly and suddenly darkened due to the fluctuation interference.
