[0050] The following description, in conjunction with the accompanying drawings, details the storage device defrosting control method, storage device defrosting control device, storage device defrosting system, storage device, electronic device, and readable storage medium provided in this application, through specific embodiments and application scenarios.

[0051] The defrosting control method for storage equipment can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0052] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).

[0053] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

[0054] The defrosting control method for storage devices provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the defrosting control method for storage devices. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The defrosting control method for storage devices provided in this application embodiment will be described below using an electronic device as the execution subject as an example.

[0055] like Figure 1As shown, the defrosting control method for the storage device includes steps 110, 120 and 130.

[0056] Step 110: Obtain the temperature, humidity, and air pressure of the target storage equipment's refrigeration chamber during the current defrosting stage.

[0057] In actual implementation, the target storage equipment can be refrigerated storage equipment, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines.

[0058] In actual operation, the current temperature inside the cooling chamber of the target storage equipment can be obtained using a temperature acquisition device installed inside. The current humidity inside the cooling chamber can be obtained using a humidity acquisition device installed inside. The current air pressure inside the cooling chamber can be obtained using an air pressure acquisition device installed inside.

[0059] Step 120: Obtain frost parameters based on temperature, humidity, and air pressure; frost parameters are used to characterize the degree of frost formation in the cooling compartment of the target storage device.

[0060] In actual operation, the difference between the current temperature and the temperature of the previous defrost cycle, the difference between the current air pressure and the air pressure of the previous defrost cycle can be obtained, and based on the humidity, the difference between the current temperature and the temperature of the previous defrost cycle, and the difference between the current air pressure and the air pressure of the previous defrost cycle, the frosting parameters can be obtained.

[0061] Step 130: Based on the frost parameters, control the defrosting device of the target storage equipment to defrost.

[0062] In practice, at least one of the following can be adjusted: defrosting power, defrosting duration, and defrosting frequency of the defrosting device. Defrosting power can be the operating power of the defrosting device used to defrost the refrigeration compartment of the target storage equipment; defrosting duration can be the running time of a single operation of the defrosting device for the defrosting process; and defrosting frequency can be the number of times the defrosting device performs defrosting per unit time.

[0063] In some embodiments, a defrosting strategy can be generated based on frost parameters, which may increase or decrease defrosting power, increase or decrease defrosting duration, and increase or decrease defrosting frequency, so as to control the target storage device to defrost based on the defrosting strategy.

[0064] In some embodiments, the frost rate of the target storage device can be obtained, and a defrosting strategy can be generated based on the frost rate.

[0065] In some embodiments, the defrosting device can be controlled based on a defrosting strategy to defrost the target storage device.

[0066] In some embodiments, after the target storage device is defrosted based on the defrosting strategy, historical temperature, historical humidity, historical pressure, and historical frost parameters can be obtained, and the defrosting of the target storage device can be optimized based on the obtained historical temperature, historical humidity, historical pressure, and historical frost parameters.

[0067] In some embodiments, after the defrosting device of the target storage device is controlled to defrost, parameters characterizing the defrosting effect of the target storage device can be obtained, and a defrosting alarm can be generated if the defrosting effect is not ideal.

[0068] According to the defrosting control method for storage equipment in this application, based on the current temperature, humidity and air pressure of the target storage equipment, a defrosting parameter is obtained to characterize the degree of frost formation in the cooling chamber of the target storage equipment. The defrosting device of the target storage equipment is then controlled to defrost based on the defrosting parameter, so that the defrosting process is based on the defrosting parameter characterizing the frost formation of the target storage equipment, thus avoiding excessive defrosting energy consumption caused by excessively high defrosting frequency.

[0069] In some embodiments, a target temperature difference and a target air pressure difference can be obtained; the target temperature difference is the difference between the temperature and the temperature of the previous defrosting stage, and the target air pressure difference is the difference between the air pressure and the air pressure of the previous defrosting stage; based on humidity, target temperature difference, air pressure and target air pressure difference, frost parameters are obtained.

[0070] In some embodiments, frosting parameters can be obtained based on the following formula, which considers humidity, target temperature difference, air pressure, and target air pressure difference:

[0071]

[0072] Where, m s denoted by frosting parameters, k represents an empirical coefficient, RH represents humidity, ΔT represents the difference between the current temperature and the temperature at the end of the previous defrosting cycle, P represents pressure, and ΔP represents the difference between the current pressure and the pressure at the end of the previous defrosting cycle.

[0073] According to the defrosting control method for storage equipment in this application, based on the current temperature, humidity and air pressure of the target storage equipment, a defrosting parameter is obtained to characterize the degree of frost formation in the cooling chamber of the target storage equipment. The defrosting device of the target storage equipment is then controlled to defrost based on the defrosting parameter, so that the defrosting process is based on the defrosting parameter characterizing the frost formation of the target storage equipment, thus avoiding excessive defrosting energy consumption caused by excessively high defrosting frequency.

[0074] In some embodiments, if the frosting parameter is greater than or equal to a first threshold, the defrosting power of the defrosting device can be increased to a first target power based on a power control strategy, and / or the defrosting duration of the defrosting device can be increased to a first target duration based on a duration control strategy; the defrosting power is the operating power of the defrosting device, and the defrosting duration is the single running duration of the defrosting device.

[0075] In actual implementation, the power control strategy may include a preset power increment or a preset power growth rate. The preset power increment can be any positive number, and when the frosting parameter is greater than or equal to a first threshold, the defrosting power of the defrosting device of the target storage equipment can be increased by at least one preset power increment.

[0076] In actual implementation, the first target power represents the required operating power of the defrosting device of the target storage equipment when the frosting parameter is greater than or equal to the first threshold. When the frosting parameter is greater than or equal to the first threshold, the defrosting power can be increased to the first target power based on a preset power increment. For example, with a first threshold of 20 and a preset power increment of 10, and a frosting parameter of 25, the operating power of the defrosting device of the target storage equipment can be adjusted from 120 to 130.

[0077] In actual execution, the preset power growth rate can be any positive number. When the frosting parameter is greater than or equal to the first threshold, the defrosting power of the defrosting device of the target storage equipment can be increased to the first target power according to the preset power growth rate.

[0078] In actual implementation, the first target power represents the operating power required for the defrosting device of the target storage equipment when the frosting parameters are greater than or equal to the first threshold. When the frosting parameters are greater than or equal to the first threshold, the defrosting power of the defrosting device can be continuously increased by 10% of the original defrosting power according to a preset power growth rate of 10%, until it reaches the first target power.

[0079] In actual implementation, the duration control strategy may include a preset duration increment or a preset duration growth rate. The preset duration increment can be any positive number, and when the frosting parameter is greater than or equal to a first threshold, the defrosting duration of the defrosting device of the target storage equipment can be increased by at least one preset duration increment.

[0080] In actual implementation, the first target duration represents the required runtime of a single operation of the defrosting device of the target storage device when the frosting parameter is greater than or equal to a first threshold. When the frosting parameter is greater than or equal to the first threshold, the defrosting duration can be increased to the first target duration based on a preset duration increment. For example, with a first threshold of 20 and a preset duration increment of 1 minute, if the frosting parameter is 25, the runtime of the defrosting device of the target storage device can be adjusted from 2 minutes to 3 minutes.

[0081] In actual execution, the preset duration growth rate can be any positive number. If the frosting parameter is greater than or equal to the first threshold, the defrosting time of the defrosting device of the target storage equipment can be increased to the first target time according to the preset duration growth rate.

[0082] In actual implementation, the first target duration represents the required runtime of a single operation of the defrosting device of the target storage equipment when the frost parameter is greater than or equal to the first threshold. When the frost parameter is greater than or equal to the first threshold, the defrosting duration of the defrosting device can be increased by 15% according to a preset duration growth rate, continuously increasing the original defrosting duration by 15% until it reaches the first target duration.

[0083] According to the defrosting control method for storage devices in this application, based on the current temperature, humidity, and pressure of the target storage device, a frosting parameter is obtained to characterize the degree of frosting in the cooling chamber of the target storage device. When the frosting parameter is greater than or equal to a first threshold, the defrosting power of the defrosting device is increased to a first target power based on a power control strategy, and / or the defrosting duration of the defrosting device is increased to a first target duration based on a duration control strategy, so as to control the target storage device to defrost. Defrosting is performed according to the frosting parameter characterizing the degree of frosting in the cooling chamber of the target storage device, so that the defrosting process is based on the frosting condition of the target storage device, avoiding excessive defrosting energy consumption caused by excessively high defrosting frequency.

[0084] In some embodiments, when the frosting parameter is less than the second threshold, the defrosting power of the defrosting device is reduced to the second target power based on a power control strategy, and / or the defrosting time of the defrosting device is shortened to the second target time based on a duration control strategy; the second threshold is less than the first threshold, the second target power is less than the first target power, and the second target time is less than the first target time.

[0085] In actual implementation, the power control strategy may include a preset power reduction or a preset power reduction rate. The preset power reduction can be any positive number, and the absolute value of the preset power reduction may not be equal to the absolute value of the preset power increment, or the absolute value of the preset power reduction may be equal to the absolute value of the preset power increment. When the frosting parameter is less than a second threshold, the defrosting power of the defrosting device of the target storage equipment can be reduced by at least one preset power reduction.

[0086] In actual implementation, the second target power represents the required operating power of the defrosting device of the target storage equipment when the frosting parameter is less than the second threshold. When the frosting parameter is less than the second threshold, the defrosting power can be reduced to the second target power based on a preset power reduction. For example, with a second threshold of 10 and a preset power reduction of 5, and a frosting parameter of 8, the operating power of the defrosting device of the target storage equipment can be adjusted from 120 to 115.

[0087] In actual execution, the preset power reduction rate can be any positive number. When the frosting parameter is less than the second threshold, the defrosting power of the defrosting device of the target storage equipment can be reduced to the second target power according to the preset power reduction rate.

[0088] In actual implementation, the second target power represents the operating power required for the defrosting device of the target storage equipment when the frosting parameters are less than the second threshold. When the frosting parameters are less than the second threshold, the defrosting power of the defrosting device can be continuously reduced by 10% at a preset power reduction rate until it reaches the second target power.

[0089] In actual implementation, the duration control strategy can include a preset duration reduction and a preset duration reduction rate. The preset duration reduction can be any positive number, and the absolute value of the preset duration reduction may not be equal to the absolute value of the preset duration increment, but it can also be equal to the absolute value of the preset duration increment. If the frosting parameter is less than a second threshold, the defrosting time of the target storage device can be reduced by at least one preset duration reduction.

[0090] In actual implementation, the second target duration represents the required runtime of a single operation of the defrosting device of the target storage device when the frosting parameter is greater than or equal to the first threshold. If the frosting parameter is less than the second threshold, the defrosting duration can be reduced to the second target duration based on a preset duration reduction. For example, with a second threshold of 10 and a preset duration reduction of 30 seconds, and a frosting parameter of 8, the runtime of the defrosting device of the target storage device can be adjusted from 2 minutes to 1 minute and 30 seconds.

[0091] In actual execution, the preset duration reduction rate can be any positive number. When the frosting parameter is less than the second threshold, the defrosting time of the defrosting device of the target storage equipment can be reduced to the second target time according to the preset duration reduction rate.

[0092] In actual implementation, the second target duration represents the required runtime of a single operation of the defrosting device of the target storage equipment when the frost parameter is greater than or equal to the first threshold. If the frost parameter is less than the second threshold, the defrosting duration of the defrosting device can be reduced by a preset reduction rate of 20%, continuously decreasing by 20% until it reaches the second target duration.

[0093] According to the defrosting control method for storage devices in this application, based on the current temperature, humidity, and pressure of the target storage device, a frosting parameter is obtained to characterize the degree of frosting in the cooling chamber of the target storage device. When the frosting parameter is less than a second threshold, the defrosting power of the defrosting device is reduced to a second target power based on a power control strategy, and / or the defrosting time of the defrosting device is shortened to a second target time based on a duration control strategy, so as to control the target storage device to defrost. Defrosting is performed according to the frosting parameter characterizing the degree of frosting in the cooling chamber of the target storage device, so that the defrosting process is based on the frosting condition of the target storage device, avoiding excessive defrosting energy consumption caused by excessively high defrosting frequency.

[0094] In some embodiments, after generating a defrosting strategy based on frost parameters and controlling the target storage device to defrost based on the defrosting strategy, historical temperature, historical humidity, historical pressure, and historical frost parameters are obtained; based on the historical temperature, historical humidity, historical pressure, and historical frost parameters, the power control strategy or duration control strategy is optimized.

[0095] In actual implementation, the relationship between historical temperature, historical humidity, historical pressure and historical frost parameter changes can be obtained, and the power control strategy or duration control strategy can be optimized based on the relationship between historical temperature, historical humidity, historical pressure and historical frost parameter changes.

[0096] In actual implementation, the relationship between historical temperature, historical humidity, historical pressure and changes in historical frost parameters can be represented by curves, bar charts, column charts, arrays, discrete points or any theoretically feasible form, and this application does not impose specific restrictions on this.

[0097] In some embodiments, historical temperature, historical humidity, historical pressure, and historical frost parameters can be obtained, and the design parameters of the target storage device (such as the evaporator surface material and refrigerant flow rate of the target storage device) can be optimized based on the historical temperature, historical humidity, historical pressure, and historical frost parameters to reduce the impact of frost on the performance of the target storage device.

[0098] According to the defrosting control method for storage equipment of this application, based on the current temperature, humidity and pressure of the target storage equipment, frosting parameters are obtained to characterize the degree of frosting in the cooling chamber of the target storage equipment. After controlling the target storage equipment to defrost based on the frosting parameters, the relationship between historical temperature, historical humidity, historical pressure and historical frosting parameter changes is obtained. Based on the relationship between historical temperature, historical humidity, historical pressure and historical frosting parameter changes, the defrosting of the target storage equipment is optimized so that the defrosting process is based on the frosting condition of the target storage equipment, avoiding excessive defrosting energy consumption caused by excessive defrosting frequency.

[0099] In some embodiments, a frosting parameter variation model can be obtained based on historical temperature, historical humidity, historical pressure, and historical frosting parameters; the frosting parameter variation model is used to characterize the relationship between temperature, humidity, pressure, and frosting parameter variation; based on the frosting parameter variation model, the power control strategy or duration control strategy is updated.

[0100] In some embodiments, the frost parameter variation model may include curves, bar charts, histograms, arrays, discrete points, or any theoretically feasible form that characterizes the relationship between historical temperature, historical humidity, historical pressure, and historical frost parameter variations.

[0101] In practice, the frost parameter variation model can be a variation curve formed by constructing a two-dimensional coordinate system with historical temperature, historical humidity, and historical pressure as one dimension and historical frost parameters as another dimension.

[0102] In some embodiments, at least one of the power control strategy and the duration control strategy may be updated based on a frosting parameter variation model that characterizes the relationship between temperature, humidity, pressure and frosting parameter variation.

[0103] In some embodiments, based on a frosting parameter change model that characterizes the relationship between temperature, humidity, pressure and frosting parameter changes, preset power increment, preset power growth rate, preset power reduction, preset power reduction rate, preset duration increment, preset duration growth rate, preset duration reduction rate and preset duration reduction can be increased or decreased, so that the adjustment range of the defrosting power and defrosting duration of the defrosting device is larger or smaller during the defrosting process controlled by the defrosting strategy.

[0104] According to the defrosting control method for storage equipment of this application, a defrosting parameter change model is obtained based on historical temperature, historical humidity, historical pressure and historical defrosting parameters; the defrosting parameter change model is used to characterize the relationship between temperature, humidity, pressure and defrosting parameter changes; based on the defrosting parameter change model, the power control strategy, the duration control strategy and the duration control strategy are updated so that the defrosting process based on the optimized defrosting strategy is maintained in a stable state.

[0105] In some embodiments, the frosting rate can be obtained based on frosting parameters; if the frosting rate is greater than a preset rate, the number of defrosting cycles of the defrosting device can be increased, and / or the defrosting time of the defrosting device can be increased.

[0106] In actual implementation, the frosting rate can characterize the frosting rate of the cooling compartment of the target storage equipment.

[0107] In actual execution, two frosting parameters calculated at intervals of time can be obtained, and the difference between the two frosting parameters can be used as the frosting rate.

[0108] In some embodiments, the frosting rate can be obtained based on the following formula:

[0109]

[0110] Where V represents the frosting rate, m1 represents the first frosting parameter acquisition, m2 represents the second frosting parameter acquisition, t1 represents the time of the first frosting parameter acquisition, and t2 represents the time of the second frosting parameter acquisition.

[0111] In actual execution, the preset rate can be any positive number.

[0112] In actual operation, the defrosting frequency of the defrosting device can be increased if the frosting rate is greater than the preset rate. For example, if the preset rate is 10 and the frosting rate is 12, the defrosting frequency of the target storage device can be changed from once per hour to twice per hour.

[0113] In actual operation, the defrosting time can be increased if the frosting rate is greater than the preset rate. For example, if the preset rate is 10 and the frosting rate is 12, the defrosting device of the target storage device can be changed from a mode of defrosting for 5 minutes each time to a mode of defrosting for 10 minutes each time.

[0114] According to the defrosting control method for storage equipment of this application, based on the current temperature, humidity and pressure of the target storage equipment, a defrosting parameter is obtained to characterize the degree of frost formation in the cooling chamber of the target storage equipment, and a defrosting rate is obtained based on the defrosting parameter. If the defrosting rate is greater than a preset rate, the number of defrosting cycles of the defrosting device is increased and / or the defrosting time is increased. Defrosting is performed according to the defrosting strategy of increasing the defrosting frequency and / or increasing the defrosting time, so that the defrosting process is based on the frost formation of the target storage equipment, avoiding excessive defrosting energy consumption caused by excessively high defrosting frequency.

[0115] In some embodiments, if the frosting parameter is greater than a third threshold, the defrosting device of the target storage device may be controlled to defrost at least one of the maximum defrosting power, the maximum defrosting duration, and the maximum defrosting frequency.

[0116] In practice, the third threshold can be any positive number. The third threshold can be greater than the first and second thresholds.

[0117] In some embodiments, if the amount of frost exceeds a third threshold, a defrosting strategy can be generated to instruct the defrosting device to defrost at the maximum defrosting power, the maximum defrosting frequency, or the maximum defrosting duration.

[0118] In some embodiments, if the amount of frost exceeds a third threshold, the target storage device can be controlled to switch from a defrosting mode with a defrosting power of 1500 watts to a defrosting mode with a maximum defrosting power of 2000 watts.

[0119] In some embodiments, if the amount of frost exceeds a third threshold, the target storage device can be controlled to change from a defrosting mode that defrosts once per hour to a maximum defrosting frequency of three times per hour.

[0120] In some embodiments, if the amount of frost exceeds a third threshold, the target storage device can be controlled to change from a defrosting mode with a defrosting duration of 10 minutes per defrost to a maximum defrosting duration of 15 minutes per defrost.

[0121] According to the defrosting control method for storage equipment of this application, based on the current temperature, humidity and pressure of the target storage equipment, a defrosting parameter is obtained to characterize the degree of frost formation in the cooling chamber of the target storage equipment. When the defrosting parameter is greater than a third threshold, the target storage equipment is controlled to defrost at the maximum defrosting power, the maximum defrosting duration or the maximum defrosting frequency, so that the defrosting process is based on the frost formation of the target storage equipment, avoiding excessive defrosting energy consumption caused by excessively high defrosting frequency.

[0122] In some embodiments, if the difference between the frost parameters before defrosting and the target frost parameters is greater than a fourth threshold, a defrosting abnormality alarm is generated; the target frost parameters are the frost parameters after defrosting for a preset duration in the current defrosting stage, and the preset duration is greater than the defrosting duration of the defrosting device.

[0123] In actual operation, the preset duration can be the duration for the defrosting device to perform one defrosting process.

[0124] In some embodiments, the difference between the frost parameters before defrosting and the target frost parameters can be obtained. If the difference between the frost parameters before defrosting and the target frost parameters is greater than a fourth threshold, a defrosting abnormality alarm is generated. The defrosting abnormality alarm is used to indicate that the defrosting effect is not ideal or the defrosting device is operating abnormally.

[0125] According to the defrosting control method for storage equipment of this application, based on the current temperature, humidity and pressure of the target storage equipment, frosting parameters are obtained to characterize the degree of frosting in the cooling chamber of the target storage equipment. A defrosting strategy is generated based on the frosting parameters to control the target storage equipment to defrost. Defrosting is performed according to the frosting parameters characterizing the degree of frosting in the cooling chamber of the target storage equipment. If the difference between the frosting parameters before defrosting and the target frosting parameters is greater than a fourth threshold, a defrosting abnormality alarm is generated to promptly troubleshoot defrosting faults in case of defrosting abnormalities, thereby ensuring the defrosting effect.

[0126] To better understand the defrosting control method for storage devices provided in the embodiments of this application, further explanation is provided below. It should be understood that the following discussion is merely exemplary.

[0127] This application provides a defrosting control method for storage equipment, the specific steps of which are as follows: Figure 2 As shown:

[0128] Step 210: Obtain the current temperature, humidity and air pressure of the target storage device.

[0129] In some embodiments, such as Figure 3 As shown, after the target storage device is powered on, its compressor and fan operate for cooling. A temperature sensor inside the cooling chamber acquires the temperature, a humidity sensor acquires the humidity, and a pressure sensor acquires the air pressure. When the temperature inside the cooling chamber is less than or equal to a fifth threshold, the compressor and fan stop operating.

[0130] In actual implementation, the target storage equipment can be refrigerated storage equipment, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines.

[0131] In actual operation, the current temperature inside the cooling chamber of the target storage device can be obtained using a temperature sensor. The current humidity inside the cooling chamber can be obtained using a humidity sensor. The current air pressure inside the cooling chamber can be obtained using a pressure sensor.

[0132] Step 220: Obtain frost parameters based on temperature, humidity, and air pressure; frost parameters are used to characterize the degree of frost formation in the cooling compartment of the target storage device.

[0133] In actual operation, the difference between the current temperature and the temperature of the previous defrost cycle, the difference between the current air pressure and the air pressure of the previous defrost cycle can be obtained, and based on the humidity, the difference between the current temperature and the temperature of the previous defrost cycle, and the difference between the current air pressure and the air pressure of the previous defrost cycle, the frosting parameters can be obtained.

[0134] In some embodiments, frosting parameters can be obtained based on temperature, humidity, and pressure using the following formula:

[0135]

[0136] Where, m s denoted by frosting parameters, k represents an empirical coefficient, RH represents humidity, ΔT represents the difference between the current temperature and the temperature at the end of the previous defrosting cycle, P represents pressure, and ΔP represents the difference between the current pressure and the pressure at the end of the previous defrosting cycle.

[0137] Step 230: When the frosting parameter is greater than or equal to the first threshold, based on the power control strategy, control the defrosting power of the defrosting device to increase to the first target power, and / or based on the duration control strategy, control the defrosting duration of the defrosting device to increase to the first target duration; the defrosting power is the operating power of the defrosting device, and the defrosting duration is the single running duration of the defrosting device.

[0138] In actual implementation, the power control strategy may include a preset power increment or a preset power growth rate. The preset power increment can be any positive number, and when the frosting parameter is greater than or equal to a first threshold, the defrosting power of the defrosting device of the target storage equipment can be increased by at least one preset power increment.

[0139] In actual implementation, the first target power represents the required operating power of the defrosting device of the target storage equipment when the frosting parameter is greater than or equal to the first threshold. When the frosting parameter is greater than or equal to the first threshold, the defrosting power can be increased to the first target power based on a preset power increment. For example, with a first threshold of 20 and a preset power increment of 10, and a frosting parameter of 25, the operating power of the defrosting device of the target storage equipment can be adjusted from 120 to 130.

[0140] In actual execution, the preset power growth rate can be any positive number. When the frosting parameter is greater than or equal to the first threshold, the defrosting power of the defrosting device of the target storage equipment can be increased to the first target power according to the preset power growth rate.

[0141] In actual implementation, the first target power represents the operating power required for the defrosting device of the target storage equipment when the frosting parameters are greater than or equal to the first threshold. When the frosting parameters are greater than or equal to the first threshold, the defrosting power of the defrosting device can be continuously increased by 10% of the original defrosting power according to a preset power growth rate of 10%, until it reaches the first target power.

[0142] In actual implementation, the duration control strategy may include a preset duration increment or a preset duration growth rate. The preset duration increment can be any positive number, and when the frosting parameter is greater than or equal to a first threshold, the defrosting duration of the defrosting device of the target storage equipment can be increased by at least one preset duration increment.

[0143] In actual implementation, the first target duration represents the required runtime of a single operation of the defrosting device of the target storage device when the frosting parameter is greater than or equal to a first threshold. When the frosting parameter is greater than or equal to the first threshold, the defrosting duration can be increased to the first target duration based on a preset duration increment. For example, with a first threshold of 20 and a preset duration increment of 1 minute, if the frosting parameter is 25, the runtime of the defrosting device of the target storage device can be adjusted from 2 minutes to 3 minutes.

[0144] In actual execution, the preset duration growth rate can be any positive number. If the frosting parameter is greater than or equal to the first threshold, the defrosting time of the defrosting device of the target storage equipment can be increased to the first target time according to the preset duration growth rate.

[0145] In actual implementation, the first target duration represents the required runtime of a single operation of the defrosting device of the target storage equipment when the frost parameter is greater than or equal to the first threshold. When the frost parameter is greater than or equal to the first threshold, the defrosting duration of the defrosting device can be increased by 15% according to a preset duration growth rate, continuously increasing the original defrosting duration by 15% until it reaches the first target duration.

[0146] Step 240: When the frosting parameter is less than the second threshold, based on the power control strategy, control the defrosting power of the defrosting device to be reduced to the second target power, and / or based on the duration control strategy, control the defrosting duration of the defrosting device to be shortened to the second target duration; the second threshold is less than the first threshold, the second target power is less than the first target power, and the second target duration is less than the first target duration.

[0147] In actual implementation, the power control strategy may include a preset power reduction or a preset power reduction rate. The preset power reduction can be any positive number, and the absolute value of the preset power reduction may not be equal to the absolute value of the preset power increment, or the absolute value of the preset power reduction may be equal to the absolute value of the preset power increment. When the frosting parameter is less than a second threshold, the defrosting power of the defrosting device of the target storage equipment can be reduced by at least one preset power reduction.

[0148] In actual implementation, the second target power represents the required operating power of the defrosting device of the target storage equipment when the frosting parameter is less than the second threshold. When the frosting parameter is less than the second threshold, the defrosting power can be reduced to the second target power based on a preset power reduction. For example, with a second threshold of 10 and a preset power reduction of 5, and a frosting parameter of 8, the operating power of the defrosting device of the target storage equipment can be adjusted from 120 to 115.

[0149] In actual execution, the preset power reduction rate can be any positive number. When the frosting parameter is less than the second threshold, the defrosting power of the defrosting device of the target storage equipment can be reduced to the second target power according to the preset power reduction rate.

[0150] In actual implementation, the second target power represents the operating power required for the defrosting device of the target storage equipment when the frosting parameters are less than the second threshold. When the frosting parameters are less than the second threshold, the defrosting power of the defrosting device can be continuously reduced by 10% at a preset power reduction rate until it reaches the second target power.

[0151] In actual implementation, the duration control strategy can include a preset duration reduction and a preset duration reduction rate. The preset duration reduction can be any positive number, and the absolute value of the preset duration reduction may not be equal to the absolute value of the preset duration increment, but it can also be equal to the absolute value of the preset duration increment. If the frosting parameter is less than a second threshold, the defrosting time of the target storage device can be reduced by at least one preset duration reduction.

[0152] In actual implementation, the second target duration represents the required runtime of a single operation of the defrosting device of the target storage device when the frosting parameter is greater than or equal to the first threshold. If the frosting parameter is less than the second threshold, the defrosting duration can be reduced to the second target duration based on a preset duration reduction. For example, with a second threshold of 10 and a preset duration reduction of 30 seconds, and a frosting parameter of 8, the runtime of the defrosting device of the target storage device can be adjusted from 2 minutes to 1 minute and 30 seconds.

[0153] In actual execution, the preset duration reduction rate can be any positive number. When the frosting parameter is less than the second threshold, the defrosting time of the defrosting device of the target storage equipment can be reduced to the second target time according to the preset duration reduction rate.

[0154] In actual implementation, the second target duration represents the required runtime of a single operation of the defrosting device of the target storage equipment when the frost parameter is greater than or equal to the first threshold. If the frost parameter is less than the second threshold, the defrosting duration of the defrosting device can be reduced by a preset reduction rate of 20%, continuously decreasing by 20% until it reaches the second target duration.

[0155] Step 250: Obtain the frosting rate based on the frosting parameters; if the frosting rate is greater than the preset rate, increase the number of defrosting cycles of the defrosting device and / or increase the defrosting time of the defrosting device.

[0156] In actual implementation, the frosting rate can characterize the frosting rate of the cooling compartment of the target storage equipment.

[0157] In actual execution, two frosting parameters calculated at intervals of time can be obtained, and the difference between the two frosting parameters can be used as the frosting rate.

[0158] In some embodiments, the frosting rate can be obtained based on the following formula:

[0159]

[0160] Where V represents the frosting rate, m1 represents the first frosting parameter acquisition, m2 represents the second frosting parameter acquisition, t1 represents the time of the first frosting parameter acquisition, and t2 represents the time of the second frosting parameter acquisition.

[0161] In actual execution, the preset rate can be any positive number.

[0162] In actual operation, the defrosting frequency of the defrosting device can be increased if the frosting rate is greater than the preset rate. For example, if the preset rate is 10 and the frosting rate is 12, the defrosting frequency of the target storage device can be changed from once per hour to twice per hour.

[0163] In actual operation, the defrosting time can be increased if the frosting rate is greater than the preset rate. For example, if the preset rate is 10 and the frosting rate is 12, the defrosting device of the target storage device can be changed from a mode of defrosting for 5 minutes each time to a mode of defrosting for 10 minutes each time.

[0164] Step 260: When the frosting parameter is greater than the third threshold, control the defrosting device of the target storage equipment to defrost at least one of the maximum defrosting power, maximum defrosting duration and maximum defrosting frequency.

[0165] In practice, the third threshold can be any positive number. The third threshold can be greater than the first and second thresholds.

[0166] In some embodiments, if the amount of frost exceeds a third threshold, a defrosting strategy can be generated to instruct the defrosting device to defrost at the maximum defrosting power, the maximum defrosting frequency, or the maximum defrosting duration.

[0167] In some embodiments, if the amount of frost exceeds a third threshold, the target storage device can be controlled to switch from a defrosting mode with a defrosting power of 1500 watts to a defrosting mode with a maximum defrosting power of 2000 watts.

[0168] In some embodiments, if the amount of frost exceeds a third threshold, the target storage device can be controlled to change from a defrosting mode that defrosts once per hour to a maximum defrosting frequency of three times per hour.

[0169] In some embodiments, if the amount of frost exceeds a third threshold, the target storage device can be controlled to change from a defrosting mode with a defrosting duration of 10 minutes per defrost to a maximum defrosting duration of 15 minutes per defrost.

[0170] In some embodiments, such as Figure 3As shown, after defrosting the target storage device, the compressor and fan are started when the temperature inside the cooling chamber reaches the compressor operating temperature. The compressor operating temperature can be a standard temperature for starting the compressor. In some embodiments, the compressor and fan are started when the compressor operating temperature is 20 degrees Celsius and the cooling chamber temperature is 22 degrees Celsius.

[0171] Step 270: If the difference between the frost parameters before defrosting and the target frost parameters is greater than the fourth threshold, a defrosting abnormality alarm is generated; the target frost parameters are the frost parameters after defrosting for a preset duration in the current defrosting stage, and the preset duration is greater than the defrosting duration of the defrosting device.

[0172] In actual operation, the preset duration can be the duration for the defrosting device to perform one defrosting process.

[0173] In some embodiments, the difference between the frost parameters before defrosting and the target frost parameters can be obtained. If the difference between the frost parameters before defrosting and the target frost parameters is greater than a fourth threshold, a defrosting abnormality alarm is generated. The defrosting abnormality alarm is used to indicate that the defrosting effect is not ideal or the defrosting device is operating abnormally.

[0174] Step 280: Obtain historical temperature, historical humidity, historical pressure, and historical frost parameters; optimize the power control strategy or duration control strategy based on the historical temperature, historical humidity, historical pressure, and historical frost parameters.

[0175] In actual implementation, the relationship between historical temperature, historical humidity, historical pressure and historical frost parameter changes can be obtained, and the power control strategy or duration control strategy can be optimized based on the relationship between historical temperature, historical humidity, historical pressure and historical frost parameter changes.

[0176] In actual implementation, the relationship between historical temperature, historical humidity, historical pressure and changes in historical frost parameters can be represented by curves, bar charts, column charts, arrays, discrete points or any theoretically feasible form, and this application does not impose specific restrictions on this.

[0177] In some embodiments, historical temperature, historical humidity, historical pressure, and historical frost parameters can be obtained, and the design parameters of the target storage device (such as the evaporator surface material and refrigerant flow rate of the target storage device) can be optimized based on the historical temperature, historical humidity, historical pressure, and historical frost parameters to reduce the impact of frost on the performance of the target storage device.

[0178] In some embodiments, a frosting parameter variation model can be obtained based on historical temperature, historical humidity, historical pressure, and historical frosting parameters; the frosting parameter variation model is used to characterize the relationship between temperature, humidity, pressure, and frosting parameter variation; based on the frosting parameter variation model, at least one of the power control strategy and the duration control strategy is updated.

[0179] In some embodiments, the frost parameter variation model may include curves, bar charts, histograms, arrays, discrete points, or any theoretically feasible form that characterizes the relationship between historical temperature, historical humidity, historical pressure, and historical frost parameter variations.

[0180] In practice, the frost parameter variation model can be a variation curve formed by constructing a two-dimensional coordinate system with historical temperature, historical humidity, and historical pressure as one dimension and historical frost parameters as another dimension.

[0181] In some embodiments, at least one of the preset power increment, preset power reduction, preset duration increment, and preset duration reduction can be increased or decreased based on a frosting parameter change model that characterizes the relationship between temperature, humidity, pressure, and frosting parameter changes.

[0182] In some embodiments, based on a frosting parameter change model that characterizes the relationship between temperature, humidity, pressure and frosting parameter changes, preset power increment, preset power growth rate, preset power reduction, preset power reduction rate, preset duration increment, preset duration growth rate, preset duration reduction rate and preset duration reduction can be increased or decreased, so that the adjustment range of the defrosting power and defrosting duration of the defrosting device is larger or smaller during the defrosting process controlled by the defrosting strategy.
