Specifically, it can be a data item correspondence relationship in a data set or a mathematical function relationship.

[0024] The preset target moisture content can be the moisture content set in advance indicating the completion of drying of the item to be dried. The moisture drying amount can refer to the mass of moisture that needs to be removed from the item to be dried in the drying stage. The method of determining the moisture drying amount according to the moisture content after dehydration, the preset target moisture content, and the mass parameter can be to multiply the moisture content after dehydration by the mass parameter to obtain the moisture content after dehydration of the item to be dried, subtract the moisture content after dehydration from the mass parameter to obtain the net mass of the item to be dried, calculate the difference between 1 and the preset target moisture content, divide the net mass of the item to be dried by this difference to obtain the mass after drying of the item to be dried, and subtract the mass after drying from the mass parameter to obtain the moisture drying amount.

[0025] The method of determining the drying temperature according to the moisture content after dehydration, the preset target moisture content, and the material parameter can be to determine the target drying temperature range according to the current material parameter and the correlation relationship between the material parameter and the suitable drying temperature range constructed in advance, and determine the target adjustment coefficient according to the current material parameter and the correlation relationship between the material parameter and the preset adjustment coefficient, determine the middle value of the target drying temperature range as the reference drying temperature, calculate the difference between the moisture content after dehydration and the preset target moisture content, multiply the difference by the target adjustment coefficient, and add the product result to the middle value to obtain the drying temperature.

[0026] The theoretical drying rate can refer to the mass of moisture removed per unit time in theory of the item to be dried in the drying stage.

[0027] The method of determining the drying duration according to the moisture drying amount and the theoretical drying rate can be to divide the moisture drying amount by the theoretical drying rate to obtain the drying duration. Associating and storing the moisture content after dehydration with the corresponding drying temperature and drying duration can obtain the second correlation relationship between the moisture content after dehydration and the drying parameters of the item to be dried during the drying stage.

[0028] The advantage of this solution 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 duration according to the moisture drying amount and the theoretical drying rate, the second correlation relationship between the moisture content after dehydration and the drying parameters of the item to be dried during the drying stage can be 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.

It can be understood that a set of combined control parameters includes a set of dehydration parameters and a set of drying parameters.

[0030] The method of determining the combined control parameters of the item to be dried in the dehydration stage and the drying stage according to the first correlation relationship and the second correlation relationship can be to determine a set of combined control parameters by taking the dehydration parameters and the drying parameters with the same associated moisture content after dehydration according to the first correlation relationship and the second correlation relationship.

It can be understood that the data set of the proposed energy consumption in the dehydration stage and the drying stage can refer to a data set composed of the proposed energy consumption in each dehydration stage and each drying stage.

[0032] Among them, to calculate the planned energy consumption in the dehydration stage, the electric power of the dehydration stage can be determined according to the parameters in the dehydration parameters except the dehydration duration, and the planned energy consumption in the dehydration stage can be calculated according to the electric power and the dehydration duration in the dehydration stage; to calculate the planned energy consumption in the drying stage, the electric power of the drying stage can be determined according to the parameters in the drying parameters except the drying duration, and the planned energy consumption in the drying stage can be calculated according to the electric power and the drying duration in the drying stage.

[0033] S105. Determine the target dehydration parameters and the target drying parameters according to the dataset of the planned energy consumption and the optimal control strategy; among them, the optimal control strategy includes an energy consumption optimal strategy and a duration optimal strategy.

[0034] The optimal control strategy can be a rule or method for determining the best operation mode of the drying equipment for the current item to be dried, aiming to achieve a specific optimization goal. Correspondingly, the target dehydration parameters and the target drying parameters are the dehydration parameters and the drying parameters in the target simultaneous control parameters that can meet the optimal control strategy determined according to the dataset of the planned energy consumption.

[0035] Specifically, the optimal control strategy can include an energy consumption optimal strategy and a duration optimal strategy.

[0036] Correspondingly, to determine the target dehydration parameters and the target drying parameters according to the dataset of the planned energy consumption and the optimal control strategy, it can be adopted that when the optimal control strategy is the energy consumption optimal strategy, the total planned energy consumption corresponding to each simultaneous control parameter is determined according to the dataset of the planned energy consumption, and the simultaneous control parameters corresponding to the minimum value among the total planned energy consumptions are determined as the target dehydration parameters and the target drying parameters; it can also be adopted that when the optimal control strategy is the duration optimal strategy, the total planned energy consumption corresponding to each simultaneous control parameter is determined according to the dataset of the planned energy consumption, the simultaneous control parameters with the total planned energy consumption less than the preset energy consumption threshold are determined as the candidate simultaneous control parameters, and the total operation duration corresponding to the candidate simultaneous control parameters is determined, and the candidate simultaneous control parameters corresponding to the minimum value among the total operation durations are determined as the target dehydration parameters and the target drying parameters.

In this way, the dehydration power participates in the operation as an algebraic term in the calculation, and finally the calculation result of the theoretical dehydration rate is obtained.

[0044] The proposed water removal amount may refer to the mass of water that can be removed from the item to be dried under a certain set of dehydration power and dehydration duration during the dehydration stage. The method of determining the proposed water removal amount based on the theoretical dehydration rate and the dehydration duration can be to multiply the theoretical dehydration rate by the dehydration duration to obtain the proposed water removal amount. In this method, the dehydration power and the dehydration duration participate in the operation as algebraic terms in the calculation, and finally the calculation result of the proposed water removal amount is obtained.

[0053] It can be understood that the safety simultaneous control parameter is the simultaneous control parameter that can ensure that the item to be dried is not damaged. According to the dehydration power safety threshold and the drying temperature safety threshold, the method for determining the safety simultaneous control parameter among the simultaneous control parameters can be to determine the simultaneous control parameter in which the dehydration power is less than the dehydration power safety threshold and the drying temperature is less than the drying temperature safety threshold as the safety simultaneous control parameter.

[0054] The method for calculating the data set of the planned energy consumption in the dehydration stage and the drying stage according to the safety simultaneous control parameter can refer to calculating the data set of the planned energy consumption in the dehydration stage and the drying stage according to the simultaneous control parameter.

[0055] The advantage of this solution is that by determining the dehydration power safety threshold and the drying temperature safety threshold according to the basic parameters, determining the safety simultaneous control parameter among the simultaneous control parameters according to the dehydration power safety threshold and the drying temperature safety threshold, and calculating the data set of the planned energy consumption in the dehydration stage and the drying stage according to the safety simultaneous control parameter, the safety and energy saving of the dehydration stage and the drying stage can be comprehensively guaranteed.

[0056] S304, calculate the data set of the planned energy consumption in the dehydration stage and the drying stage according to the simultaneous control parameter; S305, when the optimal control strategy is the energy consumption optimal strategy, determine the planned total energy consumption corresponding to each simultaneous control parameter according to the data set of the planned energy consumption; The planned total energy consumption corresponding to a simultaneous control parameter may refer to the sum of the planned energy consumption in the dehydration stage using the dehydration parameter in the simultaneous control parameter and the planned energy consumption in the drying stage using the drying parameter in the simultaneous control parameter.

[0057] S306, determine the simultaneous control parameter corresponding to the minimum value among the planned total energy consumptions as the target dehydration parameter and the target drying parameter.

[0058] By using algorithms such as simple traversal method, divide-and-conquer method or heap sorting method that can obtain the minimum value for each proposed total energy consumption, the minimum value in the proposed total energy consumption can be obtained.

[0059] The advantage of this solution is that by determining the combined control parameters corresponding to the minimum value in each proposed total energy consumption as the target dehydration parameter and the target drying parameter, the least amount of energy can be consumed on the basis of ensuring the dehumidification effect of the item to be dried, thus avoiding energy waste.

[0060] In this technical solution, optionally, according to the dataset of the proposed energy consumption and the optimal control strategy, determining the target dehydration parameter and the target drying parameter includes: In the case where the optimal control strategy is the duration-optimal strategy, determining the proposed total energy consumption corresponding to each combined control parameter according to the dataset of the proposed energy consumption; Determining the combined control parameters with the proposed total energy consumption less than the preset energy consumption threshold as candidate combined control parameters, and determining the total running duration corresponding to the candidate combined control parameters; Determining the candidate combined control parameters corresponding to the minimum value in each total running duration as the target dehydration parameter and the target drying parameter.

[0061] The preset energy consumption threshold can be a preset upper limit of the acceptable proposed total energy consumption. The candidate combined control parameters are the combined control parameters whose corresponding proposed total energy consumption is less than the preset energy consumption threshold.

[0062] The total running duration corresponding to the candidate combined control parameters can refer to the total running duration of the dehydration stage and the drying stage using the candidate combined control parameters. The way to determine the total running duration corresponding to the candidate combined control parameters can be to add the dehydration duration in the dehydration parameter and the drying duration in the drying parameter in the candidate combined control parameters to obtain the total running duration corresponding to the candidate combined control parameters.

[0063] By using algorithms such as simple traversal method, divide-and-conquer method or heap sorting method that can obtain the minimum value for each total running duration, the minimum value in the total running duration can be obtained.

[0064] The advantage of this solution is that by determining the candidate combined control parameters corresponding to the minimum value in each total running duration as the target dehydration parameter and the target drying parameter, the least amount of duration can be consumed on the basis of ensuring that the proposed total energy consumption is not too large, meeting the user's urgent dehumidification requirement for the item to be dried.
