[0030] Example 1

[0031] Figure 1 This is a flow chart of the method for determining energy-saving drying parameters provided in Example 1 of this application. Figure 1 As shown, the specific steps include:

[0032] S101, obtaining basic parameters of an item to be dried, and determining a first correlation between a moisture content of the item after dehydration and dehydration parameters in a dehydration phase based on the basic parameters; wherein the basic parameters include mass parameters and material parameters of the item to be dried, and the dehydration parameters include dehydration power and dehydration time;

[0033] First, the present application is applicable to scenarios where cleaned industrial materials or household clothes need to be dried. Based on the above usage scenarios, it can be understood that the execution subject of the present application can be the main control PC (Printed Circuit) board of the drying equipment. Specifically, the determination of the joint control parameters for the dehydration stage and the drying stage of the items to be dried, the determination of the data set for the proposed energy consumption, and the determination of the target dehydration parameters and the target drying parameters can be executed by the main control PC board. The drying equipment uses the target dehydration parameters and the target drying parameters to execute the dehydration program and the drying program to achieve the purpose of optimizing energy consumption or operating time. Among them, the drying equipment can be a device used to remove moisture from an object to make it reach a dry state.

[0034] The items to be dried may refer to items that need to be dried, such as cleaned industrial materials or household clothes. The basic parameters of the items to be dried may be a set of parameters used to describe the basic characteristics of the items to be dried, and may include mass parameters and material parameters. Specifically, the mass parameters of the items to be dried may refer to the total mass of the items to be dried themselves and the moisture inside them; the mass parameters of the items to be dried may be acquired through a pressure sensor. The material parameters of the items to be dried may refer to the type of material from which the items to be dried are made, for example, the material parameters of industrial materials may include stainless steel, aluminum, and titanium, and the material parameters of household clothes may include cotton, linen, and chemical fiber; the material parameters of the items to be dried may be manually input by the user, or may be acquired through the built-in camera to obtain image data of the items to be dried, and obtained by performing feature recognition analysis on the image data.

[0035] The dehydration stage may refer to the process stage for removing a large amount of water from the items to be dried. The dehydration stage separates the water from the items to be dried by certain means, such as spinning or blowing. The moisture content after dehydration may refer to the percentage of the mass of the remaining water inside the items to be dried after the dehydration stage to the total mass of the items to be dried and the remaining water inside them. The dehydration parameters may refer to the program operating parameters used by the drying equipment during the dehydration stage, which may include dehydration power and dehydration time. Specifically, the dehydration power may refer to the electrical power consumed by the drying equipment during the dehydration stage. The dehydration power determines the working intensity and efficiency of the dehydration stage. Specifically, the dehydration time may refer to the running time of the dehydration stage.

[0036] The first correlation between the moisture content after dehydration and the dehydration parameters in the dehydration stage can refer to the correspondence between the moisture content after dehydration of the current item to be dried after the dehydration stage and the dehydration parameters used in the dehydration stage. Specifically, it can be a correspondence between data items in a data set or a mathematical function relationship. The method of determining the first correlation between the moisture content after dehydration and the dehydration parameters in the dehydration stage based on basic parameters can be achieved by obtaining historical basic parameters, historical dehydration parameters, and corresponding historical moisture contents after dehydration, and performing regression analysis on the historical basic parameters, historical dehydration parameters, and corresponding historical moisture contents after dehydration; or by obtaining cleaning program parameters, determining the initial moisture content of the item to be dried based on material parameters and cleaning program parameters, and determining the first correlation between the moisture content after dehydration and the dehydration parameters in the dehydration stage based on the initial moisture content and quality parameters.

[0037] S102, obtaining a second correlation between the moisture content of the article to be dried after dehydration and the drying parameters in the drying stage;

[0038] The drying stage may refer to the process phase in which residual moisture within the items to be dried is further removed by heating, achieving the desired degree of dryness. Drying parameters may refer to the program operating parameters used by the drying equipment during the drying stage, and may include drying temperature and drying time. Specifically, drying temperature may refer to the temperature of the air or other medium within the drying equipment used to heat the items to be dried during the drying stage. Specifically, drying time may refer to the duration of the drying stage.

[0039] The second correlation between the moisture content after dehydration and the drying parameters in the drying stage may refer to the correspondence between the moisture content after dehydration of the current item to be dried after / before the dehydration stage and the drying parameters used in the drying stage. Specifically, it may be a correspondence between data items in a data set or a mathematical function relationship.

[0040] The second correlation relationship between the moisture content of the items to be dried after dehydration and the drying parameters in the drying stage can be obtained by obtaining historical basic parameters, historical drying parameters and corresponding historical moisture contents after dehydration, and performing regression analysis on the historical basic parameters, historical drying parameters and corresponding historical moisture contents after dehydration; the second correlation relationship between the moisture content of the items to be dried after dehydration and the drying parameters in the drying stage can also be obtained by determining the moisture drying amount according to the moisture content after dehydration, a preset target moisture content and quality parameters, determining the drying temperature according to the moisture drying amount and material parameters, determining the theoretical drying rate according to the drying temperature and material parameters, and determining the drying time according to the moisture drying amount and the theoretical drying rate.

[0041] In this technical solution, optionally, obtaining a second correlation between the moisture content of the article to be dried after dehydration and the drying parameter in the drying stage includes:

[0042] Determining the moisture drying amount according to the moisture content after dehydration, the preset target moisture content, and the quality parameter;

[0043] Determining a drying temperature according to the moisture content after dehydration, the preset target moisture content, and the material parameters, and determining a theoretical drying rate according to the drying temperature and the material parameters;

[0044] The drying time is determined according to the moisture drying amount and the theoretical drying rate, and a second correlation relationship between the moisture content of the items to be dried after dehydration and the drying parameters in the drying stage is obtained.

[0045] The preset target moisture content can be a pre-set moisture content indicating the drying completion point of the items to be dried. The moisture drying amount can refer to the mass of moisture that needs to be removed from the items to be dried during the drying phase. The moisture drying amount can be determined based on the dehydrated moisture content, the preset target moisture content, and the quality parameter. The dehydrated moisture content can be multiplied by the quality parameter to obtain the dehydrated moisture content of the items to be dried, the dehydrated moisture content can be subtracted from the quality parameter to obtain the net mass of the items to be dried, the difference between 1 and the preset target moisture content can be calculated, and the net mass of the items to be dried can be divided by the difference to obtain the dried mass of the items to be dried. The moisture drying amount can then be determined by subtracting the mass to be dried from the quality parameter to obtain the moisture drying amount.

[0046] The method of determining the drying temperature based on the moisture content after dehydration, the preset target moisture content and the material parameters can be adopted. The target drying temperature range can be determined based on the current material parameters and the correlation between the pre-constructed material parameters and the suitable drying temperature range, and the target adjustment coefficient can be determined based on the correlation between the current material parameters and the pre-constructed material parameters and the preset adjustment coefficient. The middle value of the target drying temperature range is determined as the benchmark drying temperature, the difference between the moisture content after dehydration and the preset target moisture content is calculated, the difference is multiplied by the target adjustment coefficient, and the product result is added to the middle value to obtain the drying temperature.

[0047] The theoretical drying rate refers to the calculated mass of water theoretically removed from the drying item per unit time during the drying phase. The theoretical drying rate can be determined based on the drying temperature and material parameters by obtaining the current ambient temperature and calculating the temperature difference between the drying temperature and the ambient temperature. A target thermal efficiency coefficient is determined based on the material parameters and a pre-established relationship between the material parameters and the thermal efficiency coefficient. The theoretical surface area of ​​the item to be dried is determined based on the material parameters and mass parameters. The theoretical drying rate is then calculated by multiplying the theoretical surface area, the temperature difference, the target thermal efficiency coefficient, and the moisture content after dehydration.

[0048] The drying time can be determined based on the amount of moisture dried and the theoretical drying rate by dividing the amount of moisture dried by the theoretical drying rate to obtain the drying time. By associating and storing each post-dehydration moisture content with the corresponding drying temperature and drying time, a second correlation between the post-dehydration moisture content of the item to be dried and the drying parameters during the drying stage can be obtained.

[0049] The advantage of this arrangement of the present scheme is that, by determining the moisture drying amount according to the moisture content after dehydration, the preset target moisture content and the quality parameters, determining the drying temperature according to the moisture content after dehydration, the preset target moisture content and the material parameters, and determining the theoretical drying rate according to the drying temperature and the material parameters, and finally determining the drying time according to the moisture drying amount and the theoretical drying rate, a second correlation relationship between the moisture content after dehydration of the items to be dried in the drying stage and the drying parameters is obtained, which can accurately and efficiently adapt to the drying requirements of items to be dried with different basic parameters at different moisture contents after dehydration.

[0050] S103, determining the simultaneous control parameters of the items to be dried in the dehydration stage and the drying stage according to the first association relationship and the second association relationship;

[0051] The joint control parameters of the items to be dried in the dehydration stage and the drying stage may refer to a set of program operation parameters determined by comprehensively considering the relevant factors and relationships of the dehydration stage and the drying stage in order to make the current moisture content of the items to be dried lower than the preset target moisture content. It can be understood that a set of joint control parameters includes a set of dehydration parameters and a set of drying parameters.

[0052] According to the first association relationship and the second association relationship, the method of determining the joint control parameters of the items to be dried in the dehydration stage and the drying stage can be adopted. The dehydration parameters and drying parameters associated with the same moisture content after dehydration can be determined as a set of joint control parameters according to the first association relationship and the second association relationship.

[0053] S104, calculating data sets of planned energy consumption for the dehydration stage and the drying stage respectively according to the simultaneous control parameters;

[0054] The projected energy consumption may refer to the theoretical electrical energy consumption of the drying equipment during the dehydration and drying stages, respectively, as determined based on the simultaneous control parameters. It will be appreciated that the dataset of projected energy consumption during the dehydration and drying stages may refer to a dataset consisting of the projected energy consumption for each dehydration and drying stage.

[0055] Among them, the method for calculating the planned energy consumption in the dehydration stage can be to determine the electric power in the dehydration stage based on the parameters other than the dehydration time in the dehydration parameters, and calculate the planned energy consumption in the dehydration stage based on the electric power in the dehydration stage and the dehydration time; the method for calculating the planned energy consumption in the drying stage can be to determine the electric power in the drying stage based on the parameters other than the drying time in the drying parameters, and calculate the planned energy consumption in the drying stage based on the electric power in the drying stage and the drying time.

[0056] S105 , determining target dehydration parameters and target drying parameters based on the proposed energy consumption data set and the optimal control strategy; wherein the optimal control strategy includes an energy consumption optimal strategy and a time optimal strategy.

[0057] An optimal control strategy can be a rule or method used to determine the optimal operating mode for the drying equipment for the items being dried, aiming to achieve a specific optimization goal. Accordingly, the target dehydration and drying parameters are the target simultaneous control parameters determined based on the proposed energy consumption dataset to meet the optimal control strategy.

[0058] Specifically, the optimal control strategy may include an energy consumption optimization strategy and a duration optimization strategy. It is understood that the energy consumption optimization strategy may refer to adopting a combined control parameter that minimizes the total energy consumption of the dehydration and drying stages; the duration optimization strategy may refer to adopting a combined control parameter that minimizes the total running time of the dehydration and drying stages.

[0059] Correspondingly, the target dehydration parameter and the target drying parameter are determined according to the data set of the proposed energy consumption and the optimal control strategy. When the optimal control strategy is the energy consumption optimal strategy, the proposed total energy consumption corresponding to each joint control parameter is determined according to the data set of the proposed energy consumption, and the joint control parameter corresponding to the minimum value of each proposed total energy consumption is determined as the target dehydration parameter and the target drying parameter; when the optimal control strategy is the time optimal strategy, the proposed total energy consumption corresponding to each joint control parameter is determined according to the data set of the proposed energy consumption, and the joint control parameter with a proposed total energy consumption less than the preset energy consumption threshold is determined as the candidate joint control parameter, and the total operating time corresponding to the candidate joint control parameter is determined, and the candidate joint control parameter corresponding to the minimum value of each total operating time is determined as the target dehydration parameter and the target drying parameter.

[0060] In an embodiment of the present application, basic parameters of the items to be dried are obtained, and a first correlation relationship between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage is determined based on the basic parameters; wherein, the basic parameters include mass parameters and material parameters of the items to be dried, and the dehydration parameters include dehydration power and dehydration time; a second correlation relationship between the moisture content of the items to be dried after dehydration and the drying parameters in the drying stage is obtained; based on the first correlation relationship and the second correlation relationship, joint control parameters of the items to be dried in the dehydration stage and the drying stage are determined; based on the joint control parameters, a data set of planned energy consumption for the dehydration stage and the drying stage is calculated respectively; based on the data set of planned energy consumption and the optimal control strategy, a target dehydration parameter and a target drying parameter are determined; wherein, the optimal control strategy includes an energy consumption optimal strategy and a time optimal strategy. The above-mentioned method for determining energy-saving drying parameters determines the joint control parameters according to the basic parameters of the items to be dried, and determines the target parameters according to the proposed energy consumption of the joint control parameters and the optimal control strategy. It can meet the energy-saving drying needs or emergency drying needs of the items to be dried in various situations and realize intelligent control.

[0061] Example 2

[0062] Figure 2 This is a flow chart of the method for determining energy-saving drying parameters provided in Example 2 of the present application. This solution makes a better improvement to the above-mentioned embodiment, specifically: obtaining basic parameters of the items to be dried, and determining a first correlation between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage based on the basic parameters, including: obtaining basic parameters of the items to be dried and cleaning program parameters; wherein the basic parameters include quality parameters and material parameters of the items to be dried; determining the initial moisture content of the items to be dried based on the material parameters and the cleaning program parameters; determining the first correlation between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage based on the initial moisture content and the quality parameters; wherein the dehydration parameters include dehydration power and dehydration time.

[0063] like Figure 2 As shown, the specific steps include:

[0064] S201, obtaining basic parameters of the items to be dried and cleaning program parameters; wherein the basic parameters include quality parameters and material parameters of the items to be dried;

[0065] Cleaning program parameters may refer to parameters related to the cleaning process of the items to be dried, and may include the cleaning mode, detergent dosage, and cleaning time. Cleaning program parameters may be manually input by the user, obtained by receiving data transmitted by the cleaning device, or obtained by directly reading the operating data stored by the drying device if the drying device also has a cleaning function.

[0066] S202, determining the initial moisture content of the item to be dried according to the material parameters and the cleaning program parameters;

[0067] The initial moisture content of the items to be dried may refer to the percentage of the mass of the internal water content of the items to be dried before the dehydration stage to the total mass of the items to be dried and their internal water content, that is, the moisture content of the items to be dried when completely soaked with water. Determining the initial moisture content of the items to be dried based on material parameters and cleaning program parameters may involve determining a target water absorption efficiency coefficient based on the material parameters and a pre-established correlation between the material parameters and the water absorption efficiency coefficient, and performing a weighted summation of the cleaning program parameters and the target water absorption efficiency coefficient based on a preset first weight coefficient to determine the initial moisture content of the items to be dried.

[0068] S203, determining a first correlation between the moisture content of the dried item after dehydration and a dehydration parameter in the dehydration stage based on the initial moisture content and the quality parameter; wherein the dehydration parameter includes dehydration power and dehydration time;

[0069] A method for determining a first correlation between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage based on the initial moisture content and quality parameters can be adopted. The theoretical dehydration rate can be determined based on the quality parameters and dehydration power, and the planned dehydration amount can be determined based on the theoretical dehydration rate and dehydration time. The first correlation between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage can be determined based on the initial moisture content, quality parameters and planned dehydration amount.

[0070] In this technical solution, optionally, determining a first correlation between the moisture content of the dried item after dehydration and the dehydration parameter in the dehydration stage according to the initial moisture content and the quality parameter includes:

[0071] Determining a theoretical dehydration rate according to the quality parameter and the dehydration power, and determining a planned dehydration amount according to the theoretical dehydration rate and the dehydration time;

[0072] According to the initial moisture content, the quality parameter and the planned dehydration amount, a first correlation between the moisture content of the items to be dried after dehydration and dehydration parameters in the dehydration stage is determined; wherein the dehydration parameters include dehydration power and dehydration time.

[0073] The theoretical dehydration rate refers to the calculated mass of water removed from the dried items per unit time during the dehydration phase. The theoretical dehydration rate can be determined based on the mass parameter and the dehydration power. The theoretical dehydration rate can be calculated by weighting the mass parameter and the dehydration power according to a preset second weighting coefficient. In this method, the dehydration power is included as an algebraic term in the calculation, ultimately resulting in the theoretical dehydration rate.

[0074] The target dehydration capacity refers to the amount of water that can be removed from the dried items during the dehydration phase, using a specific dehydration power and dehydration duration. To determine the target dehydration capacity based on the theoretical dehydration rate and dehydration duration, the target dehydration capacity can be calculated by multiplying the theoretical dehydration rate by the dehydration duration. In this method, the dehydration power and dehydration duration are used as algebraic terms in the calculation to ultimately determine the target dehydration capacity.

[0075] A method for determining a first correlation between the post-dehydration moisture content of the dried article and the dehydration parameter during the dehydration phase based on the initial moisture content, the quality parameter, and the intended dehydration amount can be performed by multiplying the initial moisture content by the quality parameter to obtain the initial moisture content of the dried article, calculating the difference between the initial moisture content and the intended dehydration amount, adding this difference to the net mass of the dried article, and finally dividing this difference by the sum to obtain the post-dehydration moisture content. In this method, the dehydration power and the dehydration time are used as algebraic terms in the calculation, ultimately obtaining the calculated post-dehydration moisture content. By substituting any value within the range of dehydration power and any value within the range of dehydration time, the post-dehydration moisture content associated with each dehydration power and dehydration time can be calculated, thereby obtaining the first correlation between the post-dehydration moisture content of the dried article and the dehydration parameter during the dehydration phase.

[0076] The advantage of this arrangement of the present scheme is that the theoretical dehydration rate is determined based on the quality parameters and the dehydration power, the planned dehydration amount is determined based on the theoretical dehydration rate and the dehydration time, and the first correlation between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage is determined based on the initial moisture content, the quality parameters and the planned dehydration amount. The moisture content of the items to be dried after dehydration under various adoptable dehydration parameters can be calculated, laying a sufficient data foundation for the subsequent determination of the second correlation between the moisture content after dehydration and the drying parameters and the generation of a data set for the planned energy consumption.

[0078] S205, determining the simultaneous control parameters of the items to be dried in the dehydration stage and the drying stage according to the first association relationship and the second association relationship;

[0079] S206, calculating data sets of planned energy consumption for the dehydration stage and the drying stage respectively according to the simultaneous control parameters;

[0080] S207, determining target dehydration parameters and target drying parameters according to the proposed energy consumption data set and the optimal control strategy; wherein the optimal control strategy includes an energy consumption optimal strategy and a time optimal strategy.

[0081] The benefit of this arrangement of the present scheme is that, by determining the initial moisture content of the items to be dried based on the material parameters of the items to be dried and the cleaning program parameters, and determining the first correlation between the moisture content of the items to be dried after dehydration and the dehydration parameters in the dehydration stage based on the initial moisture content and quality parameters, the dehydration characteristics of the items to be dried with various basic parameters can be accurately adapted, providing a rich data basis for the generation of a data set for the proposed energy consumption.

[0086] S302, obtaining a second correlation between the moisture content of the article to be dried after dehydration and the drying parameters in the drying stage;

[0087] S303, determining the simultaneous control parameters of the items to be dried in the dehydration stage and the drying stage according to the first association relationship and the second association relationship;

[0088] In this technical solution, optionally, after determining the simultaneous control parameters of the items to be dried in the dehydration stage and the drying stage according to the first association relationship and the second association relationship, the method further includes:

[0092] The data sets of the planned energy consumption in the dehydration stage and the drying stage are calculated respectively according to the safety joint control parameters.

[0093] The dehydration power safety threshold may refer to the maximum dehydration power that can be used while ensuring that the items to be dried are not damaged. The dehydration power safety threshold may be determined based on material parameters and quality parameters (as well as the dehydration rotation radius of the drying equipment).

[0094] The drying temperature safety threshold may refer to the maximum drying temperature that can be used while ensuring that the items to be dried are not damaged. The drying temperature safety threshold may be determined based on material parameters and the maximum heat output of the drying equipment.

[0095] It will be appreciated that the safety joint control parameter is a joint control parameter that ensures that the items to be dried are not damaged. The safety joint control parameter can be determined from the joint control parameters based on the dehydration power safety threshold and the drying temperature safety threshold. For example, the joint control parameter where the dehydration power is less than the dehydration power safety threshold and the drying temperature is less than the drying temperature safety threshold can be determined as the safety joint control parameter.

[0096] The manner of respectively calculating the data sets of the planned energy consumption in the dehydration stage and the drying stage according to the safety joint control parameters may refer to the method of respectively calculating the data sets of the planned energy consumption in the dehydration stage and the drying stage according to the joint control parameters.

[0097] The advantage of this setting of the present scheme is that by determining the dehydration power safety threshold and the drying temperature safety threshold based on the basic parameters, determining the safety joint control parameters in the joint control parameters based on the dehydration power safety threshold and the drying temperature safety threshold, and calculating the data sets of the planned energy consumption in the dehydration stage and the drying stage respectively based on the safety joint control parameters, the safety and energy saving of the dehydration stage and the drying stage can be fully guaranteed.

[0098] S304, calculating data sets of planned energy consumption for the dehydration stage and the drying stage respectively according to the simultaneous control parameters;

[0099] S305, when the optimal control strategy is an energy consumption optimal strategy, determining the proposed total energy consumption corresponding to each joint control parameter according to the proposed energy consumption data set;

[0100] The proposed total energy consumption corresponding to a simultaneous control parameter may refer to the sum of the proposed energy consumption in the dehydration stage using the dehydration parameter in the simultaneous control parameter and the proposed energy consumption in the drying stage using the drying parameter in the simultaneous control parameter.

[0101] S306: Determine the simultaneous control parameters corresponding to the minimum values ​​of the proposed total energy consumptions as the target dehydration parameters and the target drying parameters.

[0102] By using a simple traversal method, a divide-and-conquer method, a heap sort method or other algorithms capable of finding a minimum value for each proposed total energy consumption, the minimum value of the proposed total energy consumption can be obtained.

[0103] The advantage of this arrangement of the present scheme is that by determining the joint control parameters corresponding to the minimum values ​​of the proposed total energy consumption as the target dehydration parameters and the target drying parameters, the minimum energy can be consumed while ensuring the dehumidification effect of the items to be dried, thereby avoiding energy waste.

[0104] In this technical solution, optionally, the target dehydration parameters and the target drying parameters are determined based on the proposed energy consumption data set and the optimal control strategy, including:

[0105] In a case where the optimal control strategy is a duration optimal strategy, determining a proposed total energy consumption corresponding to each joint control parameter according to the proposed energy consumption data set;

[0106] Determine the joint control parameters whose total energy consumption is less than the preset energy consumption threshold as candidate joint control parameters, and determine the total operation time corresponding to the candidate joint control parameters;

[0107] The candidate joint control parameters corresponding to the minimum value of each total operation time are determined as the target dehydration parameter and the target drying parameter.

[0108] The preset energy consumption threshold may be a preset acceptable upper limit of the proposed total energy consumption. The candidate simultaneous control parameters are simultaneous control parameters whose corresponding proposed total energy consumption is less than the preset energy consumption threshold.

[0109] The total operation duration corresponding to the candidate simultaneous control parameters may refer to the total operation duration of the dehydration phase and the drying phase using the candidate simultaneous control parameters. The total operation duration corresponding to the candidate simultaneous control parameters may be determined by adding the dehydration duration in the dehydration parameter and the drying duration in the drying parameter in the candidate simultaneous control parameters to obtain the total operation duration corresponding to the candidate simultaneous control parameters.

[0110] By using a simple traversal method, a divide-and-conquer method, a heap sort method, or other algorithms that can find the minimum value for each total running time, the minimum value of the total running time can be obtained.

[0111] The advantage of this setting of the present scheme is that by determining the candidate joint control parameters corresponding to the minimum values ​​of the total operating times as the target dehydration parameters and the target drying parameters, the minimum time can be consumed while ensuring that the planned total energy consumption is not excessive, thereby meeting the user's urgent dehumidification needs for drying items.
