TECHNICAL FIELD

[0002] Kiwi fruit belongs to typical respiratory climacteric fruit. At normal temperature, the activity of the cells in the kiwi fruit itself will not be significantly restricted. During storage, the ethylene content produced by the kiwi fruit will increase over time, and the kiwi fruit is very sensitive to ethylene, which will quickly increase the respiration intensity of the kiwi fruit, so that the protopectin in the kiwi fruit is more quickly converted into water-soluble pectin, resulting in the softening and deterioration of the kiwi fruit. In order to prolong the storage time of the kiwi fruit, the existing means usually adopts low-temperature storage to inhibit the respiration intensity of the kiwi fruit, so as to prolong the storage time of the kiwi fruit.

[0003] In order to facilitate the management of the warehouse storage of kiwi fruit, the existing method often disposes the kiwi fruit of the same variety picked in different batches in the same warehouse, and realizes the storage of the kiwi fruit by uniformly controlling the temperature of the warehouse. However, in actual scenarios, the ripening levels of the kiwi fruit picked in different batches are not completely consistent. If the same storage temperature is used for storage, when the storage temperature is set to be higher, part of the kiwi fruit will be ripened in a short time, or even rotten. When the storage temperature is set to be lower, although the kiwi fruit with a higher ripening level can be taken care of, the energy cost during the storage of the kiwi fruit will be greatly increased.

DETAILED DESCRIPTION

[0017] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the following is a detailed description of a kiwifruit storage optimization management method and system proposed in accordance with the present invention in conjunction with the accompanying drawings and preferred embodiments.

[0018] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0019] The specific scheme of the kiwifruit storage optimization management method and system provided by the present invention is described in detail below with reference to the accompanying drawings.

[0020] An embodiment of a kiwifruit storage optimization management method: This embodiment proposes a kiwifruit storage optimization management method, such as Figure 1 As shown, a kiwifruit storage optimization management method of this embodiment includes the following steps: Step S1, obtaining the quantity, ethylene concentration and carbon dioxide concentration of kiwifruit in different partitions in a storage warehouse, where the temperatures of different partitions are different.

[0021] The warehouse for storing kiwifruit of the same variety is evenly divided into multiple partitions, and each partition is equipped with a refrigerator. In this embodiment, the temperature in all partitions is sequentially set and controlled at 20°C, 18°C, 16°C, 14°C, 12°C, 10°C, 8°C, 6°C, 4°C, 2°C, and 0°C by the refrigerator. One partition corresponds to one temperature. In specific applications, the implementer sets the temperature of each partition according to the specific situation. At the same time, a carbon dioxide concentration detection sensor and an ethylene concentration detection sensor are respectively set at appropriate positions in each partition, wherein the carbon dioxide concentration detection sensor is used to monitor the carbon dioxide concentration in the partition, and the ethylene concentration detection sensor is used to monitor the ethylene concentration in the partition. The carbon dioxide concentration detection sensor and the ethylene concentration detection sensor record the monitored data once every hour, and upload the data to the data cloud detection platform for subsequent data analysis. In specific applications, the implementer can set the data acquisition frequency of the sensor according to the specific situation.

[0022] The carbon dioxide concentration detection sensor and the ethylene concentration detection sensor are used to collect the ethylene concentration and the carbon dioxide concentration of each partition per hour in the current time period, the current time period being a set of all historical time points and the current time point, and the time interval between the current time point and the historical time points being less than or equal to a preset time length, in this embodiment, the preset time length is 1 week, and in specific applications, the implementer can set it according to the specific situation. Then, one day is taken as a period, the current time period is divided into multiple time periods, the last time period in the current time period is recorded as the current time period, and for any time period: the average value of all ethylene concentrations collected in the time period is taken as the ethylene concentration of the time period, and the average value of all carbon dioxide concentrations collected in the time period is taken as the carbon dioxide concentration of the time period. At the same time, the number of kiwifruits in each partition is obtained. It should be noted that in this embodiment, the number of kiwifruits in each partition is counted once a day at a fixed time.

[0023] At this point, the number of kiwifruits, the ethylene concentration and the carbon dioxide concentration in each partition in each time period in the current time period are obtained.

[0024] Step S2, according to the ethylene concentration increase, the carbon dioxide concentration increase and the temperature in each partition in the adjacent time period in the current time period, the transfer necessary index of each partition in the current time period is obtained, and the transfer partition and the candidate partition of the transfer partition are determined, wherein the current time period is the last time period in the current time period; according to the number of kiwifruits in each transfer partition and the available inventory, the temperature distribution and the transfer necessary index of the candidate region, the adaptation degree of each candidate partition to receive the kiwifruits in the corresponding partition is evaluated.

[0025] Kiwifruits will be picked when their hardness is relatively high (the original pectin content is relatively high), and will be sent to the warehouse for cold storage. From the perspective of saving the cost of maintaining cold storage, kiwifruits will be sent to the partition with a temperature of 20℃ first, and when 20℃ can no longer effectively inhibit the ripening progress of kiwifruits, the corresponding batch of kiwifruits will be sent to the subsequent partition with a lower temperature for storage. In order to realize the above-mentioned optimized management process of kiwifruit storage, it is necessary to first determine the degree to which the partition temperature of each partition restricts the ripening speed of the same batch of kiwifruits in a single day.

[0026] Kiwifruits will continuously and continuously produce ethylene during the ripening process. Ethylene promotes stronger respiration of kiwifruits, thereby promoting the ripening of kiwifruits. After the respiration embedding end reaches the peak, the pectin hydrolysis speed increases, the fruit becomes soft, the fruit stem falls off, and then the disease and rot occur.

[0027] Next, this embodiment separately analyzes each partition to determine whether the kiwifruits in each partition need to be transferred in the current time period, and selects the partitions that need to be transferred.

[0028] This embodiment takes one subzone as an example for illustration, and the method provided in this embodiment can be used to process other subzones.

[0029] Specifically, for any subzone: The greater the ethylene concentration increase and the carbon dioxide concentration increase of adjacent time periods are, the greater the progress of the kiwi fruit ripening in the subzone is. The later time period in the adjacent time periods corresponding to the maximum value of the ethylene concentration increase of the adjacent time periods of the subzone in the current time period is recorded as a first target time period; the later time period in the adjacent time periods corresponding to the maximum value of the carbon dioxide concentration increase of the adjacent time periods of the subzone in the current time period is recorded as a second target time period; wherein the ethylene concentration increase of adjacent time periods is the difference between the ethylene concentration of the later time period and the ethylene concentration of the earlier time period in the adjacent two time periods; similarly, the carbon dioxide increase of adjacent time periods is the difference between the carbon dioxide of the later time period and the carbon dioxide of the earlier time period in the adjacent two time periods.

[0030] This embodiment takes one time period as an example for illustration, and the method provided in this embodiment can be used to process other time periods. Specifically, any time period in the current time period is recorded as a candidate time period, and the temperature maturity limit value of the subzone in the candidate time period is obtained according to the time interval between the first target time period and the second target time period, the time interval between the first target time period and the candidate time period, the time interval between the second target time period and the candidate time period, and the temperature in the subzone.

[0031] In this embodiment, a specific calculation formula of the temperature maturity limit value is given, and the temperature maturity limit value of the i th subzone in the j th time period can be expressed as: wherein, the temperature maturity limit value of the i th subzone in the j th time period, the time interval between the first target time period and the j th time period, the time interval between the first target time period and the j th time period, the time interval between the second target time period and the j th time period, the temperature of the i th subzone, the exponential function with the natural constant as the base number, the preset first adjustment parameter, the normalization function.

[0032] The preset first adjustment parameter is introduced in the calculation formula of the temperature maturity limit value in this embodiment to prevent the denominator from being 0, and the preset first adjustment parameter is 0.01 in this embodiment, which can be set according to specific circumstances in specific applications. The greater the value of the product of the normalized value of the ethylene concentration increase and the normalized value of the carbon dioxide concentration increase of the kiwifruit in the i-th partition at the j-th time period, the faster the kiwifruit is in the stage of rapid ripening when the kiwifruit is stored in the i-th partition to the j-th time period. The higher the temperature of the i-th partition, the more the temperature of the i-th partition promotes the ripening of the kiwifruit. The greater the temperature ripening limit value of the i-th partition at the j-th time period, the stronger the inhibitory effect of the temperature of the corresponding partition on the ripening of the kiwifruit when the kiwifruit is stored in the i-th partition to the j-th time period.

[0033] In order to facilitate the management of the warehouse storage of kiwifruit, the existing method usually controls the temperature in all partitions at 0°C for storage, but this method will cause a large energy consumption of the kiwifruit temperature control equipment. In the actual environment, not all kiwifruit needs an environment temperature of 0°C to store for a long time. By setting different refrigeration temperatures in the warehouse partitions, the transfer storage of kiwifruit in different partitions can be arranged according to the ripening progress of the same batch of kiwifruit, the management scheme of kiwifruit storage can be optimized, and the effect of reducing the overall energy consumption can be achieved.

[0034] For the same batch of kiwifruit, the longer the storage time in the warehouse, the more the ripening process of the kiwifruit will be inhibited by low temperature, but the ripening progress of the kiwifruit will still be accumulated with the extension of the storage time in the warehouse. Therefore, the accumulation needs to be measured.

[0035] Specifically, for any partition, the product of the normalized value of the ethylene concentration increase and the normalized value of the carbon dioxide concentration increase of the partition in each two adjacent time periods in the current time period is recorded as the first product of the partition in each two adjacent time periods in the current time period. For the partition, there is a first product in each two adjacent time periods in the current time period. The first product is used for the single-day ripening progress of the kiwifruit in a single time period. The greater the value of the first product, the faster the ripening progress of the kiwifruit in the corresponding time period. In this embodiment, the maximum and minimum value normalization method is used for the normalization processing of the ethylene concentration increase and the carbon dioxide concentration increase. In specific applications, the implementer can also use other existing data normalization methods for processing. The maximum and minimum value normalization method is prior art, and will not be described in detail here.

[0036] According to the temperature ripening limit value and the first product of all time periods in the current time period, the transfer necessary index of the partition in the current time period is obtained. The temperature ripening limit value and the transfer necessary index are in a negative correlation relationship. The first product and the transfer necessary index are in a positive correlation relationship.

[0037] As a specific example, a specific calculation formula of the transfer necessary index is given. The transfer necessary index of the i-th partition in the current time period can be represented as: wherein, a transition necessity index of the ith partition in the current time period, a number of time periods in the current time period, a first product between the (n-1)th time period and the nth time period of the ith partition in the current time period, a temperature ripening limit value of the nth time period in the current time period, a normalization function.

[0038] The greater the single-day ripening progress of the ith partition in a single day and the smaller the temperature ripening limit of the ith partition in a single day, the greater the degree to which the ripening of the kiwifruit in the ith partition is not inhibited by low temperature in a single day, and the closer the kiwifruit in the ith partition is to the stage of complete ripening in a single day. The higher the accumulated ripening progress of the kiwifruit in the ith partition before the current time period, the stronger the energy of the ith partition to resist low-temperature inhibition, and the greater the need for the kiwifruit in the ith partition to be transferred to a partition with lower temperature to strengthen the inhibition of the ripening of the kiwifruit when the kiwifruit in the ith partition is stored to the current time period, that is, the greater the transition necessity index of the ith partition in the current time period.

[0039] When the kiwifruit is stored in a partition, if the low-temperature environment in the corresponding partition cannot effectively slow down the ripening speed of the kiwifruit, it is necessary to consider transferring the kiwifruit in the partition to other partitions with lower temperature for storage. Other partitions usually also store kiwifruit of other batches, and it is necessary to ensure that the transfer of the kiwifruit in the partition to other partitions with lower temperature does not greatly damage the ripening progress of the kiwifruit originally stored in the other partitions, thereby greatly shortening the ripening time of the kiwifruit in the other partitions.

[0040] For any partition, if the transition necessity index of the partition in the current time period is greater than a preset necessity threshold, the partition is taken as a to-be-transferred partition. In the embodiment, the preset necessity threshold is 0.75, and in specific applications, the implementer can set it according to the specific circumstances. For any to-be-transferred partition, a partition with a temperature lower than the to-be-transferred partition and an available inventory greater than or equal to the number of kiwifruit of the to-be-transferred partition is taken as a candidate partition of the to-be-transferred partition. By using the above method, each to-be-transferred partition and each candidate partition of each to-be-transferred partition can be screened.

[0041] Then, all the partitions are sorted in descending order of temperature, and the sequence obtained at this time is taken as a partition sequence.

[0042] The lower the temperature maintained by the refrigerator, the more energy consumed. In order to save energy as much as possible, the priority of the candidate partition with a higher ranking in the temperature sequence is higher than that of the candidate partition with a lower ranking. In summary, for any candidate partition, the less energy consumed by the candidate partition to maintain a low temperature, the stronger the ability of the candidate partition to receive the total amount of stored kiwifruit, and the greater the distance between the kiwifruit stored in the candidate partition and the fully mature kiwifruit, indicating that the impact on the storage time of the original kiwifruit in the candidate partition is lower after the kiwifruit in the corresponding partition is transferred into the candidate partition, and the kiwifruit in the partition is more suitable for being stored in the candidate partition.

[0043] For any to-be-transferred partition: The product of the normalized value of the difference between the number of kiwifruit in the to-be-transferred partition and the available inventory of each candidate region of the to-be-transferred partition and the normalized value of the order difference of the to-be-transferred partition and each candidate partition in the partition sequence is denoted as a first characteristic value.

[0044] According to the transfer necessity index of the to-be-transferred partition and the first characteristic value, the adaptation degree of each candidate partition of the to-be-transferred partition to receive the kiwifruit in the to-be-transferred partition is obtained, the transfer necessity index is in a positive correlation with the adaptation degree, and the first characteristic value is in a negative correlation with the adaptation degree.

[0045] In this embodiment, a specific calculation formula of the adaptation degree is given, and the adaptation degree of the t th candidate region of the v th to-be-transferred partition can be expressed as: wherein, indicates the adaptation degree of the t th candidate region of the v th to-be-transferred partition to receive the kiwifruit in the v th to-be-transferred partition, indicates the transfer necessity index of the v th to-be-transferred partition, indicates the number of kiwifruit in the v th to-be-transferred partition, indicates the available inventory of the t th candidate region of the v th to-be-transferred partition, indicates the order number of the v th to-be-transferred partition in the partition sequence, indicates the order number of the t th candidate region of the v th to-be-transferred partition in the partition sequence, indicates a preset first adjustment parameter, indicates a normalization function.

[0046] The preset first adjustment parameter is introduced into the calculation formula of the adaptation degree in this embodiment to prevent the denominator from being 0. In this embodiment, the preset first adjustment parameter is 0.01, and in specific applications, the implementer can set it according to the specific situation.

[0047] is used to represent the difference between the number of kiwifruits in the vth transfer partition and the available inventory of the tth candidate area, and the greater the value, the greater the difference between the two. is used to represent the order difference between the vth transfer partition and the tth candidate partition in the partition sequence, and the greater the value, the greater the order difference between the two, and the more energy saved by the vth transfer partition after transferring its kiwifruits to the tth candidate area. When the difference between the number of kiwifruits in the vth transfer partition and the available inventory of the tth candidate area is smaller, and the order difference between the vth transfer partition and the tth candidate partition in the partition sequence is also smaller, the kiwifruits in the vth transfer partition are more suitable for being transferred to the tth candidate area, that is, the tth candidate area of the vth transfer partition is more suitable for receiving the kiwifruits in the vth transfer partition.

[0048] By using the above method, the suitability of each candidate area for receiving kiwifruits in the corresponding transfer partition can be obtained.

[0049] In step S3, the kiwifruit diversity factor of each candidate area is obtained according to the number of transferred kiwifruits received by each candidate area, and the temperature difference between the partition where the transferred kiwifruits were located before being transferred and each candidate area.

[0050] Step S2 analyzes the same batch of kiwifruits, but in actual scenarios, a warehouse storing kiwifruits will receive multiple batches of kiwifruits, and there may be multiple batches of kiwifruits stored in the same partition. Due to the different storage times and transfer times of these different batches of kiwifruits in the partition, the accumulated ripening progress of these different batches of kiwifruits may be different. In order to better determine the transfer partition of the kiwifruits, it is necessary to analyze the ripening progress of the kiwifruits in different batches, and further correct the suitability to better extend the storage time of the kiwifruits on the basis of saving energy.

[0051] The present embodiment will be described below with reference to one candidate partition, and the method provided by the present embodiment can be used to process other candidate partitions.

[0052] Specifically, for any candidate partition: The temperature difference between each partition where the transferred kiwifruits of the candidate partition received in the current period were located before being transferred and the candidate partition is recorded as the first temperature difference, and the number of kiwifruits in each partition where the transferred kiwifruits of the candidate partition received in the current period were located before being transferred is recorded as the corresponding second feature value. It should be noted that each partition where the transferred kiwifruits of the candidate partition received in the current period were located before being transferred has a corresponding first temperature difference and a second feature value.

[0053] The product of the first temperature difference and the second characteristic value corresponding to each sub-area to which the kiwifruit in the candidate sub-area was transferred before being transferred is recorded as the second product of each sub-area to which the kiwifruit in the candidate sub-area was transferred before being transferred. Each sub-area to which the kiwifruit in the candidate sub-area was transferred before being transferred has a corresponding second product. The average of the second products of all sub-areas to which the kiwifruit in the candidate sub-area was transferred before being transferred is taken as the kiwifruit diversity factor for the candidate sub-area.

[0054] In this embodiment, a specific calculation formula for the kiwifruit diversity factor is given. The kiwifruit diversity factor of the tth partition to be selected in the vth partition to be transferred can be expressed as: in, represents the kiwifruit diversity factor of the tth selected partition of the vth partition to be transferred, Indicates the number of partitions where the kiwifruits in the tth selected partition of the vth partition to be transferred in the current period have been transferred before being transferred. Indicates the current period of time in which the kiwifruit that has been transferred to the selected partition is located before being transferred. The number of kiwifruit in each partition, which is also the second eigenvalue; Indicates the location of the tth selected partition of the vth partition to be transferred in the current period where the kiwifruit has been transferred before being transferred. The temperature of each zone, represents the temperature of the tth selected partition of the vth partition to be transferred, Represents the normalization function.

[0055] Indicates the relationship between the tth selected partition of the vth partition to be transferred in the current period and the kiwifruit that has received the transfer before being transferred. The temperature difference between the two partitions, that is, the first temperature difference, the larger its value is, the greater the temperature difference between the two partitions is.

[0056] The greater the temperature difference between each of the to-be-selected partitions of the vth to-be-transferred partition in the current period and the partition where the kiwifruit that has been transferred was located before being transferred, and the greater the number of kiwifruits in each of the partitions where the kiwifruit that has been transferred to the to-be-selected partition was located before being transferred in the current period, it means that the tth to-be-selected partition has received more types of kiwifruit batches, that is, the greater the kiwifruit diversity factor of the tth to-be-selected partition of the vth to-be-transferred partition, the more obvious the difference in ripening progress between different kiwifruit batches in the tth to-be-selected partition, and the more likely it is that some batches of kiwifruit have reached full maturity, while they have not been effectively detected in the partition to which they belong as a whole.

[0057] The kiwi diversity factor of each candidate subarea of each to-be-transferred subarea is obtained by using the above method.

[0058] In step S4, the target subarea of the kiwi is determined according to the fitness and the kiwi diversity factor, and the kiwi is transferred and stored.

[0059] In the above steps, the fitness of the kiwi in each candidate subarea of each to-be-transferred subarea and the kiwi diversity factor of each candidate subarea of each to-be-transferred subarea have been determined, and then the fitness and the kiwi diversity factor are combined to screen the transfer area of the kiwi in each to-be-transferred subarea.

[0060] Specifically, for any to-be-transferred subarea: The fitness of the kiwi in the to-be-transferred subarea and the kiwi diversity factor of each candidate subarea of the to-be-transferred subarea are obtained, and the acceptance index of each candidate subarea of the to-be-transferred subarea is obtained, the fitness and the acceptance index are positively correlated, and the kiwi diversity factor and the kiwi diversity factor are negatively correlated.

[0061] As a specific implementation, a specific calculation method of the acceptance index is given, which is: for any candidate subarea of the to-be-transferred subarea, the difference between the constant 1 and the kiwi diversity factor of the candidate subarea of the to-be-transferred subarea is calculated, and the product of the difference and the fitness of the kiwi in the to-be-transferred subarea received by the candidate subarea of the to-be-transferred subarea is taken as the acceptance index of the candidate subarea of the to-be-transferred subarea. By using this method, the acceptance index of each candidate subarea of the to-be-transferred subarea can be obtained. It should be noted that if the candidate subarea does not receive the transferred kiwi in the current period, the kiwi diversity factor is 0.

[0062] The larger the acceptance index is, the more suitable the kiwi of the to-be-transferred subarea is to be transferred to the corresponding candidate subarea. Therefore, in this embodiment, the candidate subarea corresponding to the maximum value of the acceptance index among all candidate subareas of the to-be-transferred subarea is determined as the target subarea of the kiwi in the to-be-transferred subarea, and the kiwi in the to-be-transferred subarea is transferred to the target subarea for storage.

[0063] By using the above method, the kiwi of all to-be-transferred subareas can be transferred.

[0064] By using the method provided in this embodiment, the storage strategy in the same kiwi storage warehouse is adjusted in time, so that the storage time of the kiwi is prolonged on the basis of saving energy.

[0065] The embodiment firstly analyzes the change relationship between the respiration intensity and ethylene release of kiwifruit in each partition according to the ethylene concentration increase amount, the carbon dioxide concentration increase amount of adjacent time periods in the current time period in each partition in the storage warehouse and the temperature in the partition, determines the cumulative ripening progress of the kiwifruit stored in each partition in each time period, measures the inhibition relationship of the temperature in different partitions on the ripening of the kiwifruit stored in the partitions, evaluates whether the kiwifruit in each partition needs to be transferred to a low-temperature partition for storage, obtains the necessary transfer index, determines the to-be-transferred partition and the corresponding to-be-selected partition, then analyzes the preservation effect of the kiwifruit transferred to the to-be-selected partition in each to-be-selected partition in combination with the quantity of the kiwifruit in each to-be-transferred partition, the available inventory of the to-be-selected area, the temperature distribution and the necessary transfer index of the to-be-selected area, obtains the adaptation degree of each to-be-selected partition to receive the kiwifruit in the corresponding partition, and quantifies the influence of the transfer of the kiwifruit stored in different to-be-transferred partitions to the to-be-selected partition on the storage time length of the original kiwifruit in the to-be-selected partition; then, according to the quantity of the kiwifruit transferred in each to-be-selected partition, the temperature difference between the partition where the kiwifruit is transferred from and each to-be-selected partition, the kiwifruit diversity factor of each to-be-selected partition is obtained, the kiwifruit diversity factor is used to reflect the performance difference of the ripening progress of different batches of kiwifruit received by the to-be-selected partition, and finally the adaptation degree is corrected by using the kiwifruit diversity factor, the target partition of the kiwifruit is determined and transferred and stored, and the storage strategy of the kiwifruit is optimized. The method provided in the embodiment can timely adjust the storage temperature of the kiwifruit in the warehouse partition according to the real-time state of the kiwifruit, prolongs the storage time length of the kiwifruit on the basis of saving energy.
