Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminals, and in particular to a gas adjustment method, device, medium, product and chip for a fruit and vegetable storage space. BACKGROUND

[0002] In some fruit and vegetable storage methods, a user can input nitrogen into a fruit and vegetable storage space through a nitrogen generator to control the oxygen concentration in the fruit and vegetable storage space to maintain a fixed value, thereby delaying the ripening of the fruits and vegetables stored in the fruit and vegetable storage space.

[0003] However, since the fruits and vegetables will undergo different physiological stages such as pre-respiratory climax, climax, and post-respiratory climax during storage, the intensity of respiration will dynamically fluctuate with the physiological stages. However, since the oxygen concentration in the fruit and vegetable storage space is a fixed value, it cannot be adjusted to follow the fluctuations, and therefore, the fruits and vegetables stored in the fruit and vegetable storage space are prone to accelerated ripening due to relatively excessive oxygen supply during the respiratory climax, and unnecessary energy consumption may occur due to relatively high oxygen concentration during the respiratory plateau. SUMMARY

[0004] To solve the problem that the fixed oxygen concentration cannot balance the ripening degree and energy consumption, the embodiments of the present application provide a gas adjustment method, device, medium, product and chip for a fruit and vegetable storage space, comprising:

[0033] Embodiments of the present application include but are not limited to a gas regulation method for a fruit and vegetable storage space, a device, a medium, a product and a chip.

[0034] It can be understood that the gas regulation method for a fruit and vegetable storage space mentioned in the embodiments of the present application can be applied to an electronic device. In some implementations, the electronic device can also be referred to as a terminal, a user equipment (UE), a mobile station or a mobile terminal (MT), etc.

[0035] It can be understood that the gas regulation method for a fruit and vegetable storage space mentioned in the embodiments of the present application can be applied to a scenario of adjusting the oxygen concentration in the fruit and vegetable storage space. As shown in the following, Figure 1 a schematic diagram of an application scenario is shown. In this scenario, the electronic device 100 can control the nitrogen generator in the fruit and vegetable storage space 200 to input nitrogen into the fruit and vegetable storage space 200 (which can also be referred to as a gas library), control the oxygen concentration in the fruit and vegetable storage space 200, thereby reducing the intensity of the respiration of the fruits and vegetables stored in the fruit and vegetable storage space 200, and slowing down the ripening of the fruits and vegetables.

[0036] To address the aforementioned problems, this application provides a gas regulation method for a fruit and vegetable storage space. In this gas regulation method, during a first time period, a first concentration of ethylene in the fruit and vegetable storage space, a first temperature of the storage space, a first type of fruit and vegetable stored in the storage space, and a first target concentration of oxygen are obtained. Based on the first concentration, first temperature, first type, and first target concentration, a first predicted respiration intensity is determined; the first predicted respiration intensity characterizes the strength of respiration of the fruit and vegetable stored in the storage space. A first power consumption of a nitrogen generator is obtained, characterizing the power consumption required for the nitrogen generator to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the storage space to the first target concentration. Based on the first predicted respiration intensity, a preset target respiration intensity, and the first power consumption, a first balance value is determined; the first balance value characterizes the balance between the strength of respiration of the fruit and vegetable stored in the storage space and the power consumption of the nitrogen generator. If the first balance value is less than the preset balance value, the oxygen concentration in the fruit and vegetable storage space is adjusted to the first target concentration.

[0037] In this way, by using ethylene concentration as a feedforward signal to dynamically adjust the oxygen concentration in the fruit and vegetable storage space, it is possible to avoid excessive respiration of fruits and vegetables, which would lead to accelerated ripening, and to avoid excessive nitrogen input into the nitrogen generator, which would result in higher costs.

[0038] The following describes the gas regulation method for fruit and vegetable storage space mentioned in the embodiments of this application.

[0039] like Figure 2 The diagram illustrates a flow chart of a gas conditioning method for a fruit and vegetable storage space. This gas conditioning method can be applied to electronic devices. For example, the gas conditioning method for a fruit and vegetable storage space may include:

[0040] S201: Within a first time period, obtain the first target concentration of oxygen, the first concentration of ethylene in the fruit and vegetable storage space, and the first temperature of the fruit and vegetable storage space; the fruit and vegetable storage space contains at least the first type of fruits and vegetables.

[0041] In some implementations, electronic devices can acquire the initial concentration of ethylene in the fruit and vegetable storage space, as collected by a laser photoacoustic spectroscopy (LPAS) sensor within a first time period. The detection wavelength of the LPAS sensor can be 1532 nm, and the reference wavelength can be 1567 nm.

[0042] It can be understood that the detection wavelength can be a characteristic absorption wavelength of ethylene molecules, the laser photoacoustic spectrum sensor can emit a light signal with the detection wavelength, and the ethylene can absorb part of the light energy when the light signal passes through the ethylene. In this way, by detecting the intensity change of the light signal, the accuracy of detecting the concentration of ethylene can be improved. Moreover, in the actual detection environment, water vapor can interfere with the light signal emitted by the laser photoacoustic spectrum sensor, therefore, by subtracting the intensity of the light signal with the reference wavelength from the intensity of the light signal with the detection wavelength, the interference of water vapor on the light signal emitted by the laser photoacoustic spectrum sensor can be reduced or eliminated, thereby further improving the accuracy of the detected first concentration of ethylene. In addition, after the laser photoacoustic spectrum collects the concentration of ethylene in the fruit and vegetable storage space, the concentration of ethylene can be input into the vortex gas path separator to remove dust interference, thereby further improving the accuracy of the detected first concentration of ethylene.

[0043] In the embodiments of the present application, by using laser photoacoustic spectrum and dual-wavelength (i.e. detection wavelength and reference wavelength) anti-interference design, the accuracy of the detected first concentration of ethylene can be improved.

[0044] It can be understood that the first time period can be a pre-set time period, for example, a fixed time period of 1 second, 1 minute, 10 minutes, 30 minutes, etc. and any time period matching the cycle period of the ethylene catalytic decomposer. The embodiments of the present application do not limit the first time period.

[0045] In some implementations of obtaining the first concentration of ethylene, since the ethylene catalytic decomposer is arranged in the fruit and vegetable storage space, the ethylene catalytic decomposer can decompose the ethylene in the fruit and vegetable storage space, thereby reducing the concentration of ethylene in the fruit and vegetable storage space and alleviating the ripening of the fruits and vegetables stored in the fruit and vegetable storage space. Therefore, the electronic device can obtain one concentration of ethylene of the laser photoacoustic spectrum sensor in the first time period, and determine the concentration as the first concentration. That is, the electronic device can obtain the concentration of ethylene in the fruit and vegetable storage space collected by the laser photoacoustic spectrum sensor in real time, and determine the concentration as the first concentration of ethylene in the fruit and vegetable storage space. In this way, the accuracy of the detected first concentration of ethylene can be improved by using real-time sampling data.

[0046] In some implementations of obtaining the first concentration of ethylene, since the ethylene catalytic decomposer is arranged in the fruit and vegetable storage space, the ethylene catalytic decomposer can decompose the ethylene in the fruit and vegetable storage space, thereby reducing the concentration of ethylene in the fruit and vegetable storage space and alleviating the ripening of the fruits and vegetables stored in the fruit and vegetable storage space. Therefore, the electronic device can obtain one concentration of ethylene of the laser photoacoustic spectrum sensor in the first time period, and determine the concentration as the first concentration. That is, the electronic device can obtain the concentration of ethylene in the fruit and vegetable storage space collected by the laser photoacoustic spectrum sensor in real time, and determine the concentration as the first concentration of ethylene in the fruit and vegetable storage space. In this way, the accuracy of the detected first concentration of ethylene can be improved by using real-time sampling data.

[0047] In some implementations of obtaining the first temperature of the fruit and vegetable storage space, the electronic device can obtain a plurality of temperatures in the first time period, and determine the first temperature of the fruit and vegetable storage space as the average of the plurality of temperatures or the average after removing the maximum and minimum values. In this way, the influence of the randomness of a single temperature sampling data on the accuracy of detecting the first temperature can be avoided.

[0048] In some implementations, the fruit and vegetable storage space can store one or more types of fruits and vegetables. For example, the fruit and vegetable storage space can store apples, blueberries, leafy vegetables, and the like. The type of fruits and vegetables stored in the fruit and vegetable storage space is not limited in the embodiments of the present application.

[0049] In some implementations of obtaining the first target oxygen concentration, the electronic device can obtain a set of candidate oxygen concentrations, the set of candidate oxygen concentrations including at least two oxygen concentrations, and obtain an oxygen concentration from the set of candidate oxygen concentrations as the first target oxygen concentration based on a preset sampling method.

[0050] The set of candidate oxygen concentrations can include a plurality of candidate oxygen concentrations in [1%, 5%], for example, the set of candidate oxygen concentrations can include 100 candidate oxygen concentrations. In this way, the electronic device 100 can determine any one of the candidate oxygen concentrations in the set of candidate oxygen concentrations as the first target oxygen concentration.

[0051] S202: determining a first predicted respiration intensity according to the first concentration, the first temperature, the first type, and the first target oxygen concentration, the first predicted respiration intensity representing the strength of the respiration of the fruits and vegetables stored in the fruit and vegetable storage space.

[0052] In some implementations of determining the first predicted respiration intensity, the electronic device can input the first concentration, the first temperature, the first type, and the first target oxygen concentration into a respiration intensity prediction model to determine the first predicted respiration intensity.

[0053] For example, the electronic device can determine an ethylene enhancement factor according to the first type parameter corresponding to the first type, the first concentration, and the reference ethylene concentration. The ethylene enhancement factor can represent the influence of the ethylene concentration in the fruit and vegetable storage space on the respiration of the fruits and vegetables stored in the fruit and vegetable storage space. For example, the higher the ethylene concentration in the fruit and vegetable storage space, the greater the ethylene enhancement factor, and the greater the influence of the ethylene concentration in the fruit and vegetable storage space on the respiration of the fruits and vegetables in the fruit and vegetable storage space, i.e., the stronger the respiration of the fruits and vegetables.

[0054] The electronic device can determine an oxygen influence factor according to the first target concentration and the first Michaelis constant corresponding to the first type. The oxygen influence factor can represent an influence degree of the oxygen concentration in the fruit and vegetable storage space on the respiration of the fruit and vegetable stored in the fruit and vegetable storage space. For example, the higher the oxygen concentration in the fruit and vegetable storage space, the greater the oxygen influence factor, and the greater the influence degree of the oxygen concentration in the fruit and vegetable storage space on the respiration of the fruit and vegetable stored in the fruit and vegetable storage space, that is, the stronger the respiration of the fruit and vegetable.

[0055] The electronic device can determine a temperature influence factor according to the first temperature and the temperature coefficient. The temperature influence factor can represent an influence degree of the temperature in the fruit and vegetable storage space on the respiration of the fruit and vegetable stored in the fruit and vegetable storage space. For example, the higher the temperature in the fruit and vegetable storage space, the greater the temperature influence factor, and the greater the influence degree of the temperature in the fruit and vegetable storage space on the respiration of the fruit and vegetable stored in the fruit and vegetable storage space, that is, the stronger the respiration of the fruit and vegetable.

[0056] Then, the electronic device can determine a first predicted respiration intensity, that is, a predicted respiration intensity of the fruit and vegetable in the fruit and vegetable storage space, according to the ethylene enhancement factor, the oxygen influence factor, and the temperature influence factor.

[0057] In some ways of determining the ethylene enhancement factor, the electronic device can determine the ethylene enhancement factor by using the following formula (1):

[0058] (1);

[0059] wherein, the ethylene enhancement factor can be represented by k, the first type parameter can be represented by k, the reference ethylene concentration can be represented by C0, and the first concentration can be represented by C1.

[0060] In some implementations, the first type parameter corresponding to different types of fruit and vegetable is different. For example, when the fruit and vegetable is an apple, the first type parameter k can be 0.25. When the fruit and vegetable is a blueberry, the first type parameter k can be 0.18. When the fruit and vegetable is a green leafy vegetable, the first type parameter can be 0.3.

[0061] In some ways of determining the oxygen influence factor, the electronic device can determine the oxygen influence factor by using the following formula (2):

[0062] (2);

[0063] wherein, the oxygen influence factor can be represented by k, the first Michaelis constant (also referred to as a half-saturation constant) can be represented by K1 / 2, and The first target concentration can be represented.

[0064] In some implementations, the first Michaelis constant can represent an oxygen concentration at which the fruit and vegetable reaches 50% of the maximum respiration rate. Also, different types of fruit and vegetables correspond to different first Michaelis constants. For example, in some implementations, the first Michaelis constant corresponding to apples is determined to be 0.5 through an in vitro mitochondrial oxygen consumption rate experiment. The first Michaelis constant corresponding to blueberries is determined to be 0.3 through a closed container respiratory quotient (RQ) tracking. The first Michaelis constant corresponding to green leafy vegetables is determined to be 0.7 through infrared oxygen absorption kinetics analysis.

[0065] It can be understood that the first Michaelis constant corresponding to different types of fruit and vegetables can also be determined in other ways, and the determination method of the first Michaelis constant corresponding to fruit and vegetables is not specifically limited in the embodiments of the present application.

[0066] In some ways of determining the temperature influence factor, the electronic device can determine the temperature influence factor using the following formula (3):

[0067] (3);

[0068] wherein, The temperature influence factor can be represented by T, The temperature coefficient can be represented by a, and the temperature coefficient of most fruit and vegetables is usually 2.0, The first temperature can be represented by T, The reference temperature can be represented by Tref, for example, the cold chain standard 4℃.

[0069] In some ways of determining the first predicted respiration intensity, the electronic device can determine the first predicted respiration intensity using the following formula (4):

[0070] (4);

[0071] wherein, The first predicted respiration intensity can be represented by R, The reference respiration rate can be represented by Rref.

[0072] In some implementations, different types of fruit and vegetables correspond to different reference respiration rates. For example, the reference respiration rate corresponding to apples can be 3.2, the reference respiration rate corresponding to blueberries can be 8.1, and the reference respiration rate corresponding to green leafy vegetables can be 6.7.

[0073] In the embodiments of the present application, through the logarithmic enhancement of ethylene, the dynamic inhibition of oxygen, and the real-time compensation of temperature, the prediction accuracy of the respiration intensity can be improved.

[0074] In another manner of determining the first predicted respiration intensity, the electronic device can obtain a second type of fruit and vegetable stored in the fruit and vegetable storage space, and determine the first predicted respiration intensity according to the first concentration, the first temperature, the first type, the second type, and the first target concentration.

[0075] For example, the electronic device can determine a first sub-predicted respiration intensity, i.e., a predicted respiration intensity of the first type of fruit and vegetable stored in the fruit and vegetable storage space, according to the first concentration, the first temperature, the first type, and the first target concentration. The electronic device can also determine a second sub-predicted respiration intensity, i.e., a predicted respiration intensity of the second type of fruit and vegetable stored in the fruit and vegetable storage space, according to the first concentration, the first temperature, the second type, and the first target concentration. Then, the electronic device can determine the first predicted respiration intensity as a maximum value of the first sub-predicted respiration intensity and the second sub-predicted respiration intensity.

[0076] In this way, by adjusting the oxygen concentration in the fruit and vegetable storage space according to the predicted respiration intensity of the fruit and vegetable of the type with the largest predicted respiration intensity among different types of fruit and vegetable stored in the fruit and vegetable storage space, the ripening of all fruit and vegetable stored in the fruit and vegetable storage space can be slowed down.

[0077] In another manner of determining the first predicted respiration intensity, the electronic device can obtain a first quantity of the first type of fruit and vegetable stored in the fruit and vegetable storage space and a second quantity of the second type of fruit and vegetable stored in the fruit and vegetable storage space, and determine the first predicted respiration intensity according to the first concentration, the first temperature, the first type, the second type, and the first target concentration, when the first quantity is greater than the second quantity.

[0078] In this way, by adjusting the oxygen concentration in the fruit and vegetable storage space according to the predicted respiration intensity of the fruit and vegetable of the type with the largest predicted respiration intensity among different types of fruit and vegetable stored in the fruit and vegetable storage space, the ripening of all fruit and vegetable stored in the fruit and vegetable storage space can be slowed down.

[0079] S203: Obtain a first power consumption of the nitrogen generator, wherein the nitrogen generator is configured to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the fruit and vegetable storage space, and the first power consumption represents a power consumption of the nitrogen generator when the oxygen concentration in the fruit and vegetable storage space is controlled to the first target concentration.

[0080] It can be understood that the electronic device can input the first target concentration of oxygen into the nitrogen generator power consumption model to determine the first power consumption corresponding to the first target concentration. The nitrogen generator power consumption model can represent the corresponding relationship between the concentration of oxygen and the power consumption of the nitrogen generator, and the first power consumption can represent the power consumption required by the nitrogen generator to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the fruit and vegetable storage space to the first target concentration.

[0081] In some implementations, the electronic device can obtain the power consumption required for the membrane separation nitrogen making machine or the membrane separation-PSA combined nitrogen making machine to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the fruit and vegetable storage space to be the first target concentration, i.e., the power consumption required for the oxygen to account for the first target concentration of the total gas (oxygen and nitrogen) volume.

[0082] It can be understood that the electronic device can also obtain the power consumption required for other nitrogen making machines to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the fruit and vegetable storage space to be the first target concentration, and the type of the nitrogen making machine is not limited in the embodiments of the present application.

[0083] S204: Determine a first balance value according to the first predicted respiration intensity, the preset target respiration intensity, and the first power consumption. The first balance value represents a balance relationship between the respiration intensity of the fruits and vegetables stored in the fruit and vegetable storage space and the power consumption of the nitrogen making machine.

[0084] In some implementations of determining the first balance value, the electronic device can determine the first balance value by using the following formula (5):

[0085] (5);

[0086] wherein, the first balance value can be represented by, the first predicted respiration intensity can be represented by, the target respiration intensity can be represented by, the first power consumption can be represented by, the weight corresponding to the respiration control can be represented by, the weight corresponding to the nitrogen cost can be represented by.

[0087] S205: In a case where the first balance value is less than a preset balance value, adjust the oxygen concentration in the fruit and vegetable storage space to the first target concentration.

[0088] It can be understood that the preset balance value can be a fixed value, and the preset balance value can also be the minimum value of the balance values corresponding to different candidate oxygen concentrations in the candidate oxygen concentration interval.

[0089] In some implementations, in a case where the first balance value is less than the preset balance value, the electronic device can determine that, when the oxygen concentration in the fruit and vegetable storage space is controlled to be the first target concentration, it can not only avoid the respiration intensity of the fruits and vegetables being too large to cause the fruits and vegetables to mature rapidly, but also avoid the nitrogen making machine inputting too much nitrogen to cause high cost.

[0090] It can be understood that the first balance value can also be greater than or equal to the preset balance value, and the implementations of the first balance value being greater than or equal to the preset balance value are introduced below.

[0091] As Figure 3 shown in FIG. 6, a flowchart of another method for gas regulation of a fruit and vegetable storage space is shown. The method for gas regulation of a fruit and vegetable storage space can be applied to an electronic device. Exemplarily, the method for gas regulation of a fruit and vegetable storage space can include:

[0092] S206: In a case where the first balance value is greater than or equal to the preset balance value, obtaining a second target concentration of oxygen.

[0093] In some implementations, in a case where the first balance value is greater than or equal to the preset balance value, the electronic device can determine, as the second target concentration of oxygen, a candidate oxygen concentration other than the first target concentration in the candidate oxygen concentration region.

[0094] S207: Determining a second predicted respiration intensity according to the first concentration, the first temperature, the first type, and the second target concentration; the second predicted respiration intensity representing a degree of strength of respiration of fruits and vegetables stored in the fruit and vegetable storage space.

[0095] S208: Obtaining a second power consumption of the nitrogen generator; the second power consumption representing a power consumption required for the nitrogen generator to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the fruit and vegetable storage space to be the second target concentration.

[0096] S209: Determining a second balance value according to the second predicted respiration intensity, the target respiration intensity, and the second power consumption; the second balance value representing a balance relationship between the degree of strength of respiration of fruits and vegetables stored in the fruit and vegetable storage space and the power consumption of the nitrogen generator.

[0097] S210: In a case where the second balance value is less than the preset balance value, adjusting the oxygen concentration in the fruit and vegetable storage space to be the second target concentration.

[0098] It can be understood that S207 to S210 are essentially the same as S202 to S205, and therefore the implementation of S207 to S210 can refer to S202 to S205, and to avoid repeated discussion, no further description is given here. In addition, in a case where the second balance value is greater than or equal to the preset balance value, the electronic device can re-determine the concentration of oxygen from the candidate oxygen concentration region, and repeat the steps of determining the predicted respiration intensity, determining the power consumption, and determining the balance value until the balance value is less than the preset balance value.

[0099] In other implementations, the electronic device can obtain the target concentration of oxygen (e.g., the first target concentration or the second target concentration mentioned above) of the fruit and vegetable storage space by using a dynamic programming objective function (6) as shown below:

[0100] (6);

[0101] in, This can represent the first predicted respiratory intensity. It can represent the target breathing intensity. This can represent the first power consumption. This can represent the weights corresponding to respiratory control. It can represent the weight corresponding to the cost of nitrogen.

[0102] It is understood that the gas conditioning method for fruit and vegetable storage space mentioned in the embodiments of this application can be applied to a gas conditioning system. The gas conditioning system is described below.

[0103] like Figure 4 The diagram shows a schematic of a gas regulation system. In some implementations, the gas regulation system may include an oxygen sensor, a laser photoacoustic spectroscopy sensor, a temperature sensor, a fruit and vegetable type input module, a respiration intensity prediction model module, a gas proportion optimizer, a nitrogen generator control unit, a membrane separation-PSA combined nitrogen generator, and a gas storage and gas circulation module.

[0104] Among them, the oxygen sensor can be used to collect the real-time concentration of oxygen in the storage space of fruits and vegetables.

[0105] The laser photoacoustic spectroscopy sensor can be used to collect the first concentration of ethylene in the fruit and vegetable storage space within a first time period, and input the first concentration of ethylene in the fruit and vegetable storage space into the respiration intensity prediction model module.

[0106] The temperature sensor can be used to collect the first temperature in the fruit and vegetable storage space within the first time period and input the first temperature of the fruit and vegetable storage space into the respiration intensity prediction model module.

[0107] The fruit and vegetable type input module can be used to input the first type of fruits and vegetables stored in the fruit and vegetable storage space into the respiration intensity prediction model module.

[0108] The respiration intensity prediction model module can be used to determine the first predicted respiration intensity based on the first concentration, first temperature, first type, and first target concentration. The first predicted respiration intensity characterizes the strength of respiration in the fruits and vegetables stored in the storage space.

[0109] The nitrogen generator control unit can be used to obtain the first power consumption of the nitrogen generator, which can characterize the power consumption required for the nitrogen generator to input nitrogen into the fruit and vegetable storage space to control the oxygen concentration in the fruit and vegetable storage space to the first target concentration.

[0110] The gas ratio optimizer can be used to determine a first balance value based on a first predicted breathing intensity, a preset target breathing intensity, and a first power consumption.

[0111] The nitrogen generator control unit can be configured to, in a case where the first balance value is less than the preset balance value, determine a volume of nitrogen to be input into the fruit and vegetable storage space according to the real-time concentration of nitrogen in the fruit and vegetable storage space and the first target concentration of oxygen in the fruit and vegetable storage space, until the real-time concentration of oxygen in the fruit and vegetable storage space is the same as the first target concentration of oxygen, and stop inputting nitrogen into the fruit and vegetable storage space.

[0112] The membrane separation-PSA composite nitrogen generator can be configured to input nitrogen into the fruit and vegetable storage space according to the determined volume of nitrogen to be input into the fruit and vegetable storage space. For example, when the first concentration of ethylene is greater than 1 ppm, the membrane separation-PSA composite nitrogen generator is in an activated pulse nitrogen injection mode (i.e., the control flow is greater than 80 m 3 / min), and when the concentration of ethylene is less than 0.1 ppm, the membrane separation-PSA composite nitrogen generator is in a dispersion mode (i.e., the control flow is less than 20 m 3 / min).

[0113] The gas library gas circulation module can include an ethylene catalytic decomposer, which can be configured to decompose ethylene in the fruit and vegetable storage space, thereby reducing the concentration of ethylene in the fruit and vegetable storage space and alleviating the ripening of the fruits and vegetables in the fruit and vegetable storage space.
