It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1 is a schematic flow chart of a drying method provided in an embodiment, which is applicable to the situations of processing an electrical curve of a drying device, accurate drying judgment of clothes in the drying device, and the like, and the method can be implemented by the drying device provided by the invention, and the device can be implemented in a form of hardware and/or software, and in a specific embodiment, the device can be integrated in an electronic device. The following embodiment will be described taking the example of the integration of the apparatus in an electronic device, and referring to fig. 1, the method specifically includes the following steps:
s101, acquiring an electrical relative value curve of clothes to be dried in the drying equipment.
The drying degree of the clothes to be dried is related to the water content of the clothes to be dried, and whether the clothes to be dried are dried or not can be determined through the water content of the clothes to be dried.
The electrical relative value curve may be understood as an attribute curve of the laundry to be dried, and is used for representing the laundry moisture content of the laundry to be dried, where the electrical relative value curve includes a capacitance relative value curve, an electric field relative value curve, a wireless field relative value curve, and the like, which is not limited in this embodiment.
Specifically, a sensor for detecting the water content of the clothes to be dried is arranged in the drying equipment, and an electrical relative value curve of the clothes to be dried can be determined according to detection data of the sensor. Taking a capacitive sensor and a capacitance relative value curve as an example, the capacitive sensor can detect the capacitance value of a capacitor arranged between two polar plates of the drying equipment, a certain conversion relation exists between the capacitance value and the moisture content of clothes, and the moisture content of the clothes can be determined through the detected capacitance value and the conversion relation. However, when there is no laundry between the electrode plates, the capacitive sensor will also detect a capacitance value, that is, a capacitance value of the parasitic capacitance, which affects the accuracy of laundry drying, so that when laundry drying is performed, drying cannot be performed by the absolute value of the detected capacitance, and drying needs to be performed by the relative value of the capacitance. The electrical relative value curve in this embodiment can be understood as a curve which is obtained by processing the absolute value of the capacitor and can accurately represent the water content of the laundry to be dried.
The advantage of this arrangement is that a curve accurately representing the moisture content of the laundry to be dried can be obtained, and the interference caused by the interference device of the drying equipment to the laundry drying process is reduced.
S102, determining a reference electrical curve of the clothes to be dried based on the electrical relative value curve, the first preset time length and the second preset time length.
The water content of the clothes to be dried is dynamically changed in the process of drying the clothes to be dried by the drying equipment, and the sensor can acquire an electrical value corresponding to the water content of the clothes to be dried in real time. The sensor acquires a large number of electrical values during the laundry drying process. The electrical relative value curve is a curve formed by electrical relative values corresponding to the electrical values obtained by the sensor, and the data volume in the curve is still large, if the clothes are judged to be dry directly according to the electrical relative value curve of the clothes to be dried, the data operation amount of the processor is large, the processing time is long, the processing efficiency is low, and the waste of operation resources can be caused.
The first preset duration may be understood as a time parameter for simplifying the data amount in the electrical relative value curve, where the first preset duration includes 50 ms, 200 ms, 1 second, etc., and the specific duration may be set and adjusted according to the rotation speed of the drying device and the drying requirement, for example, the first preset duration is set to be the time required for one rotation of the drying drum of the drying device.
Specifically, the electrical property relative value curve is divided into a plurality of sub-electrical property relative value curves according to a first preset duration, the characteristic values in the sub-electrical property relative value curves are respectively determined, and the characteristic value curve for determining the reference electrical property curve of the clothes to be dried is formed according to the characteristic values in the sub-electrical property relative value curves. The characteristic value can represent each electrical property relative value in the sub-electrical property relative value curve, and the setting has the advantages that the data volume of the electrical property relative value can be reduced while the characteristic electrical property relative value is maintained, so that the data operation volume of a processor is reduced, and the drying judging time of clothes is shortened.
The characteristic value curve can be processed to obtain a reference electrical curve with less data quantity and the attribute information of the clothes, so that the performance of the drying judging system can be improved.
The second preset duration may be understood as a time parameter for simplifying the data amount in the characteristic value curve, specifically, the second preset duration is an integer multiple of the first preset duration, and the specific duration may be set and adjusted according to the rotation speed of the drying apparatus, the drying requirement, and the processing rule of the drying data, for example, the second preset duration is set to five times of the first preset duration, the second preset duration is set to eight times of the first preset duration, the second preset duration is set to nine times of the first preset duration, and the embodiment is not limited thereto.
Specifically, the simplification of the characteristic value curve is the same as the simplification of the electrical relative value curve. The characteristic value curves are divided into a plurality of sub-characteristic value curves according to a second preset duration, reference electrical values in the sub-characteristic value curves are respectively determined, and the reference electrical curves of the clothes to be dried are formed according to the reference electrical values in the sub-characteristic value curves. The reference electrical value is an electrical value capable of representing the characteristics of each electrical relative value in the sub-characteristic value curve.
The advantage of setting up like this is that reduce the data volume of electrical property relative value when keeping the moisture content information of clothing that waits to dry, reduces the data operand of treater, shortens the dry time of judgement of clothing.
S103, determining a drying parameter curve of the clothes to be dried based on the reference electrical curve and the drying parameter calculation method.
The method for calculating the dry-judging parameter can be understood as a method for extracting characteristic information of each electrical relative value in the reference electrical curve, the method for calculating the dry-judging parameter comprises proportional integral operation, mean value operation and the like, and the characteristic information of each electrical relative value in the reference electrical curve can be understood as a dry-judging parameter value obtained by calculating each electrical relative value in the reference electrical curve.
For example, assuming that the dry-judging parameter calculating method is proportional integral operation, proportional integral operation is performed on each electrical relative value in the reference electrical curve, interference of factors such as environment and the like on each electrical relative value in the reference electrical curve is filtered, a plurality of dry-judging parameter values are obtained, and a normalized curve, namely the dry-judging parameter curve, is formed by the plurality of dry-judging parameter values.
The setting has the advantages that a drying parameter curve with smaller fluctuation amplitude can be obtained, whether the clothes to be dried are dried or not is judged based on the drying parameter curve, and the accuracy of drying judgment can be improved.
S104, judging whether the clothes to be dried are dried or not based on the drying judgment parameter curve.
Specifically, determining whether the laundry to be dried has been dried based on the drying parameter curve may be understood as determining whether the laundry to be dried has been dried based on the drying parameter value in the drying parameter curve and the drying condition of the laundry. The drying condition may be that a continuous preset number of drying parameter values are smaller than a drying threshold, and the preset number may be set and adjusted according to a specific drying requirement and drying judgment logic, which is not limited in this embodiment.
For example, assuming that the drying condition is that all of the consecutive 5 drying parameter values are smaller than the drying threshold, when the consecutive 5 drying parameter values smaller than the drying threshold appear in the drying parameter curve, the laundry to be dried is considered to have been dried, otherwise, the laundry to be dried is considered to have not been dried.
The advantage of drying the laundry is considered to be that the accuracy of drying the laundry can be improved and the erroneous judgment phenomenon caused by the fluctuation of the individual drying parameter values can be reduced only when the continuous preset number of drying parameter values in the drying parameter curve are smaller than the drying threshold of the laundry.
According to the technical scheme, an electrical relative value curve of clothes to be dried in the drying equipment is obtained; determining a reference electrical curve of the clothes to be dried based on the electrical relative value curve, the first preset time length and the second preset time length; determining a drying parameter curve of the clothes to be dried based on the reference electrical curve and the drying parameter calculation method; and judging whether the clothes to be dried are dried or not based on the drying judging parameter curve. The method has the advantages that the electrical relative value curve of the clothes to be dried in the drying equipment can be processed according to the first preset time length and the second preset time length, the reference electrical curve of the clothes to be dried is determined, the drying parameter curve for judging whether the clothes to be dried is obtained on the basis of the reference electrical curve by combining the drying parameter calculation method, the fluctuation of the drying parameter curve is small, the accuracy of drying judgment can be improved, the data size of the drying parameter curve is far smaller than that of the electrical relative value curve, whether the clothes to be dried are dried is determined according to the drying parameter curve, the data operation amount is small, and the processing time is short. The method solves the problems that the relative value is determined according to the electrical absolute value of a large amount of electrical data generated in the clothes drying process, whether clothes are dried or not is determined based on the electrical relative value, the data operation amount is large, the processing time is long, the fluctuation of the relative value is large, and misjudgment is easy to cause.
Example two
Fig. 2a is a schematic flow chart of a drying method provided in the second embodiment, where the present embodiment is applicable to situations such as processing an electrical curve of a drying apparatus and accurate drying judgment of clothes in the drying apparatus, and the method may be performed by the drying apparatus provided in the present invention, and the apparatus may be implemented in a form of hardware and/or software, and in a specific embodiment, the apparatus may be integrated in an electronic device. The following embodiment will be described taking the example of the integration of the device in an electronic apparatus, referring to fig. 2a, the method specifically comprises the following steps:
s201, acquiring an electrical relative value curve of clothes to be dried in the drying equipment.
Specifically, the obtaining of the electrical relative value curve of the laundry to be dried in the drying apparatus may be understood as obtaining an attribute curve of the moisture content of the laundry to be dried in the drying apparatus, for example, a capacitance relative value curve, an electric field relative value curve, a wireless field absolute value curve, etc., and the specific attribute curve type may be determined according to the sensor type of the drying apparatus and the drying judgment processing logic, which is not limited in this embodiment.
In an embodiment, S201 may specifically include: determining an electrical absolute value curve of clothes to be dried based on the sensor; determining a high envelope curve and a low envelope curve corresponding to the electrical absolute value curve; an electrical relative value curve is determined based on the high envelope curve and the low envelope curve.
The electrical value of any detection time detected by the sensor can be understood as a fluctuation range, the high-envelope curve can be understood as a curve composed of the highest electrical value in the electrical value range, the low-envelope curve can be understood as a curve composed of the smallest electrical value in the electrical value range, and the electrical relative value curve can be understood as an electrical value curve corresponding to the clothes to be dried, which is determined by the relative change information of the high-envelope curve and the low-envelope curve.
Specifically, fig. 2b is a schematic diagram of an electrical relative value curve provided in the second embodiment, and it can be seen from the diagram that the electrical relative value changes, i.e. the water content of the laundry gradually decreases.
The advantage of setting like this is that can reduce parasitic device, stoving environment to the influence of electrical property value, confirm the electrical property relative value curve that can accurately express the water content change of clothing.
S202, determining a maximum electrical curve of the clothes to be dried based on the electrical relative value curve and the first preset time period.
The first preset duration may be understood as a time parameter for simplifying the data amount in the electrical relative value curve, where the first preset duration includes 50 ms, 200 ms, 1 second, and the like, and the specific duration may be set and adjusted according to the rotation speed and the drying requirement of the drying device, for example, the first preset duration is set to be a time required for one rotation of the drying drum of the drying device, which is not limited in this embodiment.
In an embodiment, S202 may specifically include: dividing the electrical relative value curve into a plurality of first sub-curves based on a first preset duration; determining the maximum electrical relative value of each first sub-curve respectively; and determining a maximum electrical property curve of the clothes to be dried based on the maximum electrical property relative values of all the first sub-curves.
For example, assuming that the first preset time period is a time (X seconds) required for one rotation of the drying drum of the drying apparatus, the electrical property relative value curve is divided into a plurality of sub-electrical property relative value curves based on the time period of X seconds, and then a maximum electrical property curve of the laundry to be dried is determined according to a maximum electrical property relative value in each sub-electrical property relative value curve. The maximum electrical property relative value in each sub-electrical property relative value curve represents the highest water content of the clothes to be dried in the preset time period, whether the clothes are dried or not is determined based on the highest water content, and the accuracy of the judging result is high, so that the maximum electrical property relative value in the sub-electrical property relative value curve can be understood as the characteristic value of the sub-electrical property relative value curve. Fig. 2c is a schematic diagram of a maximum electrical characteristic curve according to the second embodiment, and it can be seen from the figure that the data amount of the electrical characteristic curve is greatly reduced compared with that of the electrical characteristic curve, and the variation and fluctuation of the electrical characteristic are gradually clear.
The arrangement has the advantages of reducing the data volume of the electrical relative value, reducing the data operation volume of the processor and saving the operation resource of the processor.
S203, determining a reference electrical curve of the clothes to be dried based on the maximum electrical curve and the second preset time period.
The second preset duration may be understood as a time parameter for simplifying the data amount in the maximum electrical curve, specifically, the second preset duration is an integer multiple of the first preset duration, and the specific duration may be set and adjusted according to the rotation speed of the drying device, the drying requirement, and the processing rule of the drying data, for example, the second preset duration is five times of the first preset duration, the second preset duration is eight times of the first preset duration, the second preset duration is nine times of the first preset duration, and the embodiment is not limited thereto.
Optionally, the second preset duration includes N sub-durations, where N is a positive integer; determining a reference electrical characteristic of the laundry to be dried based on the maximum electrical characteristic and a second preset time length, including: according to the sequence from the small sub-length to the large sub-length, determining a current intermediate curve of the clothes to be dried according to the last intermediate curve and the ith sub-length of the clothes to be dried, wherein i is more than or equal to 1 and less than or equal to N, and when i is more than or equal to 1, the last intermediate curve is the maximum electrical curve; the current middle curve determined when i=n is taken as the reference electrical curve.
The size of N is related to the processing mode of the maximum electrical curve and the determination rule of the reference electrical curve. For example, if the curve obtained by performing the first processing on the maximum electrical curve based on the second preset duration can meet the judgment condition of the reference electrical curve, the size of N is 1, and if the curve obtained by performing the second processing on the maximum electrical curve based on the second preset duration can meet the judgment condition of the reference electrical curve, the size of N is Z.
For example, when N is 1, the maximum electrical curve is divided into a plurality of sub-maximum electrical curves based on the second preset duration, the reference electrical values in the sub-maximum electrical curves are respectively determined, and the reference electrical curves of the laundry to be dried are formed according to the reference electrical values in the sub-maximum electrical curves. When N is 2, sorting two sub-time periods in a second preset time period according to the sequence from smaller sub-time period to larger sub-time period, dividing the maximum electrical characteristic curve into a plurality of sub-maximum electrical characteristic curves based on the 1 st sub-time period, respectively determining reference electrical values in each sub-maximum electrical characteristic curve, forming a current middle curve of the clothes to be dried according to the reference electrical values in each sub-maximum electrical characteristic curve, dividing the current middle curve into a plurality of sub-current middle curves based on the 2 nd sub-time period, respectively determining reference electrical values in each sub-current middle curve, and forming a reference electrical characteristic curve of the clothes to be dried according to the reference electrical values in each sub-current middle curve. Similarly, when N is greater than 2, the sub-lengths are ordered in order from smaller to larger according to the sub-lengths, and then the current intermediate curve (1 is less than or equal to i < N) or the reference electrical period (i=n) of the clothes to be dried is determined based on the maximum electrical curve (i=1) or the last intermediate curve (1 is less than or equal to i is less than or equal to N) and the ith sub-length of the clothes to be dried. The specific determining process may be understood as determining a first intermediate curve of the laundry to be dried based on the maximum electrical curve and the 1 st sub-time period, determining a second intermediate curve of the laundry to be dried based on the first intermediate curve and the 2 nd sub-time period, and repeatedly performing the determining step of the intermediate curve until the reference electrical curve of the laundry to be dried is determined based on the N-1 st intermediate curve and the N-th sub-time period of the laundry to be dried.
Specifically, the ratio of the ith sub-duration to the (i-1) th sub-duration is k, the ratio of the (1) st sub-duration to the first preset duration is m, and k and m are integers greater than or equal to 3. It should be noted that the ratio of the ith sub-duration to the (i-1) th sub-duration may be the same or different, and the specific ratio may be set and adjusted according to the application and processing logic of the drying apparatus, and the embodiment is not limited thereto, assuming that the 2 nd sub-duration is 5 times the 1 st sub-duration, the 3 rd sub-duration may be 5 times the 2 nd sub-duration, and the 3 rd sub-duration may be 7 times the 2 nd sub-duration.
k. m is an integer greater than or equal to 3, so as to reduce interference of the maximum electrical value and the minimum electrical value in the maximum electrical curve (the previous current intermediate curve) when determining the current intermediate curve (the reference electrical curve). The problems that the maximum electrical value and the minimum electrical value generated under extreme conditions cause interference to the dry judging action, and the dry judgment is wrong or the dry judgment is not timely are avoided.
Further, determining the current middle curve of the laundry to be dried based on the last middle curve of the laundry to be dried and the ith sub-duration includes: dividing the last intermediate curve into a plurality of second sub-curves based on the ith sub-duration; sorting the electrical relative values included in each second sub-curve respectively, and determining the middle electrical value of each second sub-curve based on the sorting result and the selection rule, wherein when i=1, the number of the electrical relative values included in each second sub-curve is m, and when 1 is more than or equal to N, the number of the electrical relative values included in each second sub-curve is k; and determining a current middle curve of the clothes to be dried based on the middle electric values of all the second sub-curves.
Taking the second sub-curve as an example, the selection rule may be understood as a selection method of the characteristic electrical value in the second sub-curve, and the intermediate electrical value may be understood as the characteristic electrical value of the second sub-curve. Specifically, the purpose of ordering the electrical relative values included in each second sub-curve is to know the magnitude of each electrical value in the second sub-curve, so as to select the intermediate electrical value of the second sub-curve based on the selection rule. The intermediate electrical value can be understood as the characteristic parameter of the second sub-curve which filters out the interference factors.
For example, assuming that i is 1, the last intermediate curve is the maximum electrical curve, the 1 st sub-duration of the second preset duration is 5 times of the first preset duration, the selection rule is to select the next maximum electrical value as the intermediate electrical value, divide the maximum electrical curve into a plurality of sub-maximum electrical curves based on the 1 st sub-duration, respectively sort 5 electrical values in each sub-maximum electrical curve, select the next maximum electrical value in each sub-maximum electrical curve as the intermediate electrical value, and determine the first current intermediate curve of the laundry to be dried according to each intermediate electrical value.
Further, when N is 1, the first current middle curve is the reference electrical curve of the laundry to be dried. When N is greater than 1, the second current intermediate curve and the third current intermediate curve … … need to be continuously determined until i=n, and the nth current intermediate curve is determined to be the reference electrical curve.
S204, performing proportional integral operation on the reference electrical curve to determine a drying parameter curve of the clothes to be dried.
Specifically, the proportional integral operation can eliminate residual differences of the reference electrical curve, and the dry judgment parameter with small fluctuation amplitude and more accurate electrical value is obtained.
For example, fig. 2d is a schematic diagram of comparison between a maximum electrical curve and a dry-judging parameter curve according to the second embodiment, and it can be seen from the figure that, compared with the maximum electrical curve, the dry-judging parameter curve is a stable curve without clutter, the change amplitude of the dry-judging parameter curve is small, and the interference information is effectively filtered by the proportional integral operation, so that the accuracy of dry-judging can be improved.
S205, judging whether the clothes to be dried are dried or not based on the drying judgment parameter curve.
Specifically, determining whether the laundry to be dried has been dried based on the drying parameter curve may be understood as determining whether the laundry to be dried has been dried based on each drying parameter value in the drying parameter curve and the drying condition of the laundry.
For example, assuming that the drying condition is that all of the consecutive 5 drying parameter values are smaller than the drying threshold, when the consecutive 5 drying parameter values smaller than the drying threshold appear in the drying parameter curve, the laundry to be dried is considered to have been dried, otherwise, the laundry to be dried is considered to have not been dried.
According to the technical scheme, an electrical relative value curve of clothes to be dried in the drying equipment is obtained; determining a maximum electrical curve of the clothes to be dried based on the electrical relative value curve and the first preset time length; determining a reference electrical curve of the clothes to be dried based on the maximum electrical curve and the second preset time length; proportional integral operation is carried out on the reference electrical curve, and a drying parameter curve of the clothes to be dried is determined; and judging whether the clothes to be dried are dried or not based on the drying judging parameter curve. The method comprises the steps of determining a maximum electrical curve of clothes to be dried according to a first preset duration and an electrical relative value curve, determining a reference electrical curve of the clothes to be dried according to a second preset duration and the maximum electrical curve, performing proportional integral operation on the reference electrical curve to obtain a drying parameter curve for judging whether the clothes to be dried are dried, wherein the data volume of the drying parameter curve is far smaller than that of the electrical relative value curve, determining whether the clothes to be dried are dried according to the drying parameter curve, and the drying parameter curve has small data operation volume, short processing time and small fluctuation of the drying parameter curve, effectively filters interference information and can improve the accuracy of drying judgment. The method solves the problems that the relative value is determined according to the electrical absolute value of a large amount of electrical data generated in the clothes drying process, whether clothes are dried or not is determined based on the electrical relative value, the data operation amount is large, the processing time is long, the fluctuation of the relative value is large, and misjudgment is easy to cause.
