[0002] With the improvement of living standards, the demand for drying wet clothes is increasing, and drying wet items with dryers has become a common phenomenon.

[0003] Currently, there are two main methods for detecting the drying status of objects: one is to determine whether the object is dry by the drying time, and the other is to determine whether the object is dry by a temperature sensor. Both methods of determining drying are difficult to accurately determine the moisture content of the object, which leads to problems such as the object being too dry or not dry enough, resulting in inaccurate drying. Summary of the Invention

[0004] Based on the above research, this invention provides a drying state detection method, which aims to accurately obtain the moisture content of the object to be dried, thereby accurately judging the drying state effect, avoiding the situation where the dried object is too dry or not dried enough, and improving drying efficiency.

[0023] If the difference between the current moisture content and the target moisture content of the object to be dried is within the preset moisture content range, the object to be dried is determined to be dried.

[0024] In one possible implementation of the present invention, after detecting whether the object to be dried has been dried based on the target moisture content and the current moisture content, the process includes:

[0025] Obtain the moisture content and weight of the object to be dried at each moment;

[0028] In one possible implementation of the present invention, based on the moisture content and weight of the object to be dried at each moment, information on the change in moisture content and weight of the object to be dried is obtained, including:

[0029] The moisture content and weight of the object to be dried are calculated separately at each time point to obtain the moisture content difference result and the weight difference result;

[0030] Based on the moisture content difference results and the weight difference results, information on moisture content change and weight change is obtained.

[0031] Secondly, embodiments of the present invention provide a drying status detection device, the device comprising:

[0045] This invention discloses a drying status detection method, apparatus, device, and storage medium. By acquiring the target moisture content of the object to be dried, the dried weight of the object in the drying state, and the current weight of the object at the current moment, the current moisture content of the object is obtained based on the dried weight and the current weight. Then, based on the target moisture content and the current moisture content, it is detected whether the object has been dried. Thus, by obtaining the current moisture content of the object based on its dried weight and current weight in the drying state, the moisture content of the object can be accurately obtained, thereby achieving the effect of accurately determining whether the object has been dried and avoiding situations where the object is over-dried or under-dried.

[0046] The following describes a drying status detection method, apparatus, device, and storage medium provided by embodiments of the present invention.

[0047] The drying status detection method provided in this embodiment of the invention can be executed by an electronic device with executable instructions.

[0048] In one alternative implementation, the electronic device is the drying device itself. In another implementation, the electronic device can be a device connected to the drying device, which acquires data from the drying device to detect the drying status.

[0049] In this invention, the aforementioned executable electronic device can specifically implement the following: by acquiring the target moisture content of the object to be dried, the dried weight of the object in the drying state, and the current weight of the object to be dried at the current moment; by obtaining the current moisture content of the object to be dried based on the dried weight and the current weight of the object to be dried at the current moment; and by detecting whether the object to be dried has been dried based on the target moisture content and the current moisture content.

[0050] In this embodiment of the invention, the electronic device and the drying device can communicate via network through any communication method, including but not limited to mobile communication based on the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), and World Wide Interoperability for Microwave Access (WiMAX), or computer network communication based on the TCP / IP Protocol Suite (TCP / IP) and User Datagram Protocol (UDP).

[0051] It should be noted that the above system scenario is merely an example. The electronic devices and scenarios described in this invention are intended to more clearly illustrate the technical solutions of this invention and do not constitute a limitation on the technical solutions provided by this invention. As those skilled in the art will know, with the evolution of systems and the emergence of new business scenarios, the technical solutions provided by this invention are equally applicable to similar technical problems.

[0052] like Figure 1 As shown, Figure 1 This is a schematic flowchart of a drying status detection method provided in an embodiment of the present invention. Figure 1 As shown, it should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0053] The drying status detection method provided in this embodiment of the invention includes steps S101 to S103:

[0054] S101. Obtain the target moisture content of the object to be dried, the dried weight of the object in the drying state, and the current weight of the object to be dried at the current moment.

[0055] The objects to be dried can be classified according to their material, such as wool, cotton, linen, etc. The target moisture content varies depending on the material of the object to be dried. The drying equipment is preset with target moisture content for different materials.

[0056] Target moisture content refers to the water content in the object to be dried, that is, the ratio of the water content of the object in its dry state to its weight in the dry state. The target moisture content of the object to be dried is determined by its material; different materials have different target moisture contents. The drying equipment has preset target moisture content values, and different target moisture content values ​​correspond to different objects to be dried. For example, the moisture content value for wool to be dried will be higher than the standard dry moisture content value for cotton and linen.

[0057] "Drying state" refers to the state of the object to be dried at the target moisture content. The dried weight of the object in the drying state refers to the weight of the object at the target moisture content. The dried weight of the object in the drying state is calculated and stored in the memory of the drying equipment.

[0058] The current weight of the object to be dried represents the weight obtained during the drying process. The weight of the object to be dried can be obtained through a gravity sensor.

[0059] To avoid inaccurate weight readings due to malfunctioning gravity sensors, multiple gravity sensors can be installed inside the dryer to obtain the current weight of the object to be dried at any given moment.

[0060] Furthermore, the median value of the current weight of the object to be dried at the current moment can be obtained from multiple gravity sensors. Then, it can be determined whether the difference between the current weight obtained by each gravity sensor and the median value is within a preset range. If it is within the preset range, the current weight obtained by that gravity sensor is determined to be a valid value. If it is not within the preset range, the current weight obtained by that gravity sensor is determined to be an invalid value. Then, the average value of the valid current weights is taken as the final current weight of the object to be dried at the current moment.

[0061] Specifically, determining whether the difference between the current weight obtained by each gravity sensor and the median value is within a preset range can be done by determining whether the difference between the current weight obtained by each gravity sensor and the median value is within 15 percent of the median value.

[0062] S102. Based on the drying weight and the current weight of the object to be dried at the current moment, obtain the current moisture content of the object to be dried.

[0063] The current moisture content of an object to be dried refers to the ratio of water contained in the object at the current moment. The current weight is the weight of the object during the drying process at the current moment. Therefore, the drying weight of the object in the drying state and the current weight can be used to calculate the current moisture content of the object.

[0064] In this embodiment of the invention, the current weight, i.e. the weight of the object to be dried at the current moment, including the weight of water contained at the current moment, can be obtained by the gravity sensor in the drying equipment. Based on the difference between the current weight and the dried weight of the object to be dried in the drying state, the weight of water in the object to be dried can be obtained. Then, based on the ratio of the weight of water to the dried weight of the object to be dried in the drying state, the percentage of the weight of water to the dried weight of the object to be dried in the drying state can be obtained, which is the current moisture content of the object to be dried.

[0065] S103. Based on the target moisture content and the current moisture content, detect whether the object to be dried has been dried.

[0066] To determine whether an object to be dried has been dried, a preset unit value can be set. By using the preset unit value and the target moisture content, a moisture content range can be obtained. Then, it can be determined whether the current moisture content of the object to be dried is within the moisture content range. For example, if the preset unit value is 'a', the moisture content range determined by the target moisture content and the preset unit value is [target moisture content - a, target moisture content + a]. If the current moisture content is between the target moisture content plus 'a' and the target moisture content minus 'a', then it can be determined that the object to be dried has been dried.

[0067] In this embodiment of the invention, based on the moisture content range, it is determined whether the current moisture content at each time point is within the moisture content range. If the current moisture content is within the moisture content range, it is detected that the object to be dried has been dried. If the current moisture content is not within the moisture content range, the drying process continues. This achieves the effect of accurately determining whether the object to be dried has been dried, and avoids the situation where the dried object is over-dried or under-dried.

[0068] The drying state detection method disclosed in this invention obtains the target moisture content of the object to be dried, the dried weight of the object in the drying state, and the current weight of the object at the current moment. Based on the dried weight and the current weight of the object, the current moisture content of the object is obtained. Then, based on the target moisture content and the current moisture content, it is detected whether the object has been dried. In this way, the current moisture content of the object can be obtained based on the dried weight and the current weight of the object in the drying state, which can accurately determine whether the object has been dried and avoid the situation of the object being over-dried or under-dried.

[0069] Based on the fact that the current moisture content can be corrected by adjusting the drying weight of the object to be dried in the drying state, the steps in this embodiment before obtaining the target moisture content of the object to be dried, the drying weight of the object to be dried in the drying state, and the current weight of the object to be dried at the current moment may include:

[0070] When the object to be dried is drying at a preset time, obtain the first weight and first humidity value of the object at the preset time.

[0071] The drying weight of the object under drying conditions is obtained based on the first weight and first humidity value of the object at a preset time.

[0072] The preset time represents the time during the drying process of the object to be dried. For example, the preset time can be the fifth minute after the drying begins.

[0073] The first weight refers to the weight of the object to be dried as measured by the gravity sensor in the drying equipment at a preset time. The first weight is the sum of the weight of the water contained in the object to be dried and the drying weight at the preset time.

[0074] The first humidity value represents the humidity value inside the drying equipment measured by the humidity sensor at a preset time, and this humidity value inside the drying equipment is regarded as the humidity value of the object to be dried.

[0075] In this embodiment of the invention, after obtaining the first weight and first humidity value of the object to be dried at a preset time, the dried weight of the object under drying conditions, i.e., the weight of the object under drying when the moisture content is zero, can be obtained by the formula G1 = W1 / (1+S1). Wherein, the first weight is W1, the first humidity value is S1, and the dried weight of the object under drying conditions is G1.

[0076] Since the drying process may require more than one confirmation of the dried weight of the object in the drying state, multiple preset times can be set to confirm the dried weight of the object in the drying state. For example, the preset times include a first preset time and a second preset time. In this embodiment, the step of obtaining the dried weight of the object in the drying state based on the first weight and the first humidity value of the object at the preset times may include:

[0077] The first drying weight of the object to be dried in the drying state is obtained based on the first weight and the first humidity value of the object at the first preset time.

[0078] The second drying weight of the object to be dried in the drying state is obtained based on the first weight and the first humidity value of the object at the second preset time; the second preset time is a preset time after the first preset time.

[0079] If the second drying weight is inconsistent with the first drying weight, the second drying weight is determined to be the drying weight of the object to be dried in the drying state; or, the drying weight of the object to be dried in the drying state is obtained based on the average of the first drying weight and the second drying weight.

[0080] There may be multiple preset times. The drying weight under the preset time is confirmed multiple times. In this embodiment, a first preset time and a second preset time are set according to the drying process. The second preset time is the preset time after the first preset time.

[0081] In this embodiment of the invention, assuming that the first weight obtained by the dryer at the first preset time is Wp1 and the first humidity value is Sp1, the first drying weight Gp1 of the object to be dried in the drying state can be obtained according to the formula Gp1=Wp1 / (1+Sp1). Similarly, assuming that the first weight of the object to be dried at the second preset time is Wp2 and the first humidity value is Sp2, the second drying weight Gp2 of the object to be dried in the drying state can be obtained according to the formula Gp2=Wp2 / (1+Sp2).

[0082] The theoretical weight of an object in its dry state is fixed and depends only on the object itself. However, during the drying process, the weight of the object in its dry state is calculated based on other changing values. Therefore, the weight of the object in its dry state may be inaccurate. Furthermore, an inaccurate weight of the object in its dry state will directly affect the drying equipment's control of the current moisture content during the drying process. Obtaining a relatively accurate weight of the object in its dry state is crucial for the control process of the drying equipment in this invention.

[0083] In this embodiment of the invention, it is determined whether the first drying weight and the second drying weight obtained at the first preset time and the second preset time are consistent. This can be achieved by subtracting the first drying weight from the second drying weight and using a preset drying weight threshold to determine the difference. If the difference is greater than the preset drying weight threshold, it may indicate a problem with the drying equipment's determination of weight or humidity values ​​during the drying process, leading to a large difference between the first and second drying weights. Generally, the second drying weight is more accurately determined as the actual drying weight of the object under drying conditions. Therefore, the second drying weight can be determined as the actual drying weight of the object under drying conditions, or the actual drying weight of the object under drying conditions can be obtained by averaging the first and second drying weights. Of course, in other embodiments, the drying weight of the object under drying conditions can be determined by combining weight and humidity values ​​from more preset times (e.g., three or more). For example, the case with two preset times can be referred to.

[0084] The accuracy of humidity value acquisition is closely related to the humidity level inside the drying equipment. The steps for determining the current moisture content of the object to be dried, based on the drying weight and the current weight of the object at that moment, may include:

[0085] Get the current humidity value;

[0086] If the current humidity value is less than the target humidity value, the difference between the drying weight and the current weight is determined. Based on the ratio of the difference to the drying weight, the current moisture content of the object to be dried is obtained.

[0087] If the current humidity value is not less than the target humidity value, the moisture content of the object to be dried is obtained based on the current weight and the current humidity value. The current moisture content of the object to be dried is obtained based on the ratio of the moisture content to the drying weight.

[0088] During the drying process, the humidity sensor in the drying equipment continuously acquires the humidity value inside the drying equipment. The humidity value of the object to be dried cannot be obtained directly through the humidity sensor. When the humidity value inside the drying equipment is high enough, it can be determined that the humidity value of the object to be dried is approximately equal to the humidity value inside the drying equipment. Therefore, the humidity value inside the drying equipment can be regarded as the humidity value of the object to be dried. However, when the humidity value inside the drying equipment is too low, due to the limitations of the humidity sensor element, the humidity value inside the drying equipment cannot be measured, or the humidity value inside the drying equipment cannot be accurately measured, and thus the humidity value of the object to be dried cannot be obtained.

[0089] In this embodiment of the invention, a target humidity value corresponding to each object to be dried is pre-set in the drying equipment according to the material of the object to be dried. The user selects the material of the object to be dried in the drying equipment, and the drying equipment can obtain the target humidity value of the object to be dried. If the current humidity value is less than the target humidity value, it indicates that the humidity value in the drying equipment is low. At this time, the humidity value measured by the humidity sensor in the drying equipment may be inaccurate or the humidity value may not be measured. Therefore, the calculation of moisture content based on the humidity value may lead to a large error in the moisture content. The current moisture content of the object to be dried cannot be calculated by the humidity value. It is necessary to determine the difference between the drying weight and the current weight, and then calculate the current moisture content of the object to be dried based on the ratio of the difference to the drying weight. For example, if the drying weight is Gx and the current weight is Wx, the formula Hx=(Wx-Gx / Gx)*100% can be used to calculate the current moisture content of the object to be dried, where the current moisture content of the object to be dried is Hx.

[0090] Understandably, during the drying process, the target moisture content and current weight remain constant. The current moisture content changes with the drying weight of the object to be dried. The current moisture content refers to the amount of water currently contained in the object to be dried during the drying process. The value of the moisture content is negatively correlated with the drying weight of the object in the drying state. That is, if the drying weight of the object in the drying state increases, the moisture content value decreases, and if the drying weight of the object in the drying state decreases, the moisture content value increases. By calculating and adjusting the drying weight of the object in the drying state, the current moisture content can be corrected and the drying process can be controlled. Therefore, by obtaining the latest drying weight of the object to be dried at a preset time, the moisture content of the object to be dried during the drying process can be corrected.

[0091] In this embodiment of the invention, if the current humidity value is not less than the target humidity value, the measured current humidity value in the drying equipment can be equivalent to the humidity value of the object to be dried. Based on the current weight and the current humidity value, the moisture content of the object to be dried is obtained. Based on the ratio of the moisture content to the drying weight, the current moisture content of the object to be dried is obtained. For example, if the drying weight is Gx, the current humidity value is Sx, and the current weight is Wx, the formula Hx=((Sx*Wx) / Gx)*100% can be used to calculate the current moisture content of the object to be dried, where the current moisture content of the object to be dried is Hx.

[0092] Since the moisture content of the object to be dried in the drying equipment is an important indicator for determining whether the object has been dried, this embodiment includes the following steps for detecting whether the object has been dried based on the target moisture content and the current moisture content:

[0093] Determine whether the difference between the current moisture content and the target moisture content of the object to be dried is within the preset moisture content range;

[0094] If the difference between the current moisture content and the target moisture content of the object to be dried is within the preset moisture content range, the object to be dried is determined to be dried.

[0095] Based on the current moisture content of the object to be dried, its drying state can be determined. When the moisture content of the object is equal to the target moisture content, it can be determined that the object is dried. However, the target moisture content is a value based on the ideal state preset for the object. In actual operation of the drying equipment, it is difficult for the current moisture content of the object to be dried to be exactly equal to the target moisture content. That is to say, there is a certain unit value error between the current moisture content and the target moisture content. Within the unit value range, there may be two situations: one is that the current moisture content is greater than the target moisture content. In this case, if the drying equipment continues to dry, the current moisture content may be slightly less than the target moisture content, resulting in over-drying of the object. In this case, the current moisture content can be considered to be approximately equal to the target moisture content. The other situation is that the current moisture content is less than the target moisture content. In this case, it has been over-dried and cannot be reversed, and drying should be stopped immediately. Since the over-drying is slight, the current moisture content can be considered to be approximately equal to the target moisture content. Therefore, if there is a certain unit value fluctuation between the current moisture content and the target moisture content, the current moisture content can be considered equivalent to the target moisture content.

[0096] In some embodiments of the present invention, a preset moisture content range is set based on the difference between the current moisture content and the target moisture content of the object to be dried and the unit value, wherein the unit value can be a. The preset moisture content range can be (-a, a). If the difference between the current moisture content and the target moisture content of the object to be dried is within (-a, a), the current moisture content of the object to be dried can be taken as equal to the target moisture content, and it can be determined that the object to be dried has been dried.

[0097] Since the changes in moisture content and weight during the drying process are predictable, the steps following the determination of whether the object to be dried has been dried, based on the target moisture content and the current moisture content, can include:

[0098] Obtain the moisture content and weight of the object to be dried at each moment;

[0099] Based on the moisture content and weight of the object to be dried at each moment, information on the change in moisture content and weight of the object to be dried is obtained.

[0100] The operating status of the drying equipment is obtained based on the changes in moisture content and weight of the object to be dried.

[0101] In this embodiment of the invention, the moisture content and weight value are obtained at each moment during the drying process. These values ​​can be fitted into a function curve, revealing a regular trend in the change of moisture content and weight value as drying progresses. Based on the moisture content and weight value at each moment of the experimental data, a standard moisture content change curve and a standard weight value change curve can be fitted. Further analysis of these curves reveals the trends in standard moisture content and standard weight value changes. Alternatively, the trends in moisture content and standard weight value changes can be derived by differentiating the standard moisture content change function and the standard weight value change function. Since the trends in moisture content and standard weight value changes of objects of the same material within the drying equipment should be the same as those obtained from the experimental data, the operating status of the drying equipment can be determined by analyzing the trends in moisture content and standard weight value changes in the current data of the drying equipment.

[0102] For example, if the experimental data shows a standard moisture content change curve that first decreases sharply and then decreases slowly, while the current moisture content change curve of the drying equipment shows a continuous slow decrease, this indicates that the drying equipment is operating abnormally. Alternatively, if the experimental data shows a standard weight value change trend that first decreases sharply and then decreases slowly, while the current weight value change curve of the drying equipment shows no change, this also indicates that the drying equipment is operating abnormally. If the standard weight value change trend is first sharp decrease and then slow decrease, and the current moisture content change trend of the drying equipment is also first sharp decrease and then slow decrease, and simultaneously, the standard weight value change trend is first sharp decrease and then slow decrease, and the current weight value change trend of the drying equipment is also first sharp decrease and then slow decrease, then the drying equipment is operating normally. In some embodiments, the step of obtaining the moisture content change information and weight change information of the object to be dried based on the moisture content and weight value of the object at each moment may include:

[0103] The moisture content and weight of the object to be dried are calculated separately at each time point to obtain the moisture content difference result and the weight difference result;

[0104] Based on the moisture content difference results and the weight difference results, information on moisture content change and weight change is obtained.

[0105] Differential operation refers to subtracting the moisture content and weight value obtained at each previous moment from the moisture content and weight value obtained at the next moment during the drying process, to obtain an array of moisture content difference arrays and weight value difference arrays for each previous moment and the next moment.

[0106] In this embodiment of the invention, the moisture content and weight value at each moment during the drying process are obtained. Based on differential operations, arrays of moisture content differences and weight value differences for each preceding and following moment are obtained. For example, the initial moment is T0, the first moment is T1, the second moment is T2, ..., the moment before the first preset moment is Tn1-1, the first preset moment is Tn1, the moment after the first moment is Tn1+1, ... The moisture content and weight value at each moment are then differentially processed to obtain a moisture content difference array (...). The moisture content at time T1 - moisture content at time T0, (moisture content at time T2 - moisture content at time T1), ..., (moisture content at time Tn1 - moisture content at time Tn1-1), (moisture content at time Tn1+1 - moisture content at time Tn1), ..., and the weight value difference array (weight value at time T1 - weight value at time T0), (weight value at time T2 - weight value at time T1), ..., (weight value at time Tn1 - weight value at time Tn1-1), (weight value at time Tn1+1 - weight value at time Tn1), ...

[0107] During the drying process, the drying process continues, and the moisture content difference and weight difference results gradually decrease over time, meaning the rate of change of moisture content and weight values ​​decreases. Ideally, fitting curve analysis of the moisture content difference and weight difference results shows that they decrease linearly over time. By analyzing the fitting curves of the moisture content difference and weight difference results, the moisture content difference function and weight difference function are obtained. By differentiating the difference result function and the weight difference result function respectively, we can obtain the curve change trends of the moisture content difference result curve and the weight difference result curve. The drying equipment has pre-stored the curve change trends of the moisture content difference result curve and the weight difference result curve obtained during the experimental drying process of objects of different materials. By comparing the curve change trends of the current moisture content difference result curve and the weight difference result curve with the curve change trends of the experimental moisture content difference result curve and the weight difference result curve, we can obtain the moisture content change information and the weight change information.

[0108] This invention discloses a drying status detection method, apparatus, device, and storage medium. By acquiring the target moisture content of the object to be dried, the dried weight of the object in the drying state, and the current weight of the object at the current moment, the current moisture content of the object is obtained based on the dried weight and the current weight. Then, based on the target moisture content and the current moisture content, it is detected whether the object has been dried. Thus, by obtaining the current moisture content of the object based on its dried weight and current weight in the drying state, the moisture content of the object can be accurately obtained, thereby achieving the effect of accurately determining whether the object has been dried and avoiding situations where the object is over-dried or under-dried.
