[0002] With the development of global trade, the demand for long-distance cold chain transportation of fruits is increasing. However, fruits that ripen quickly (such as apples, bananas, pears, etc.) are prone to accelerate ripening due to the large amount of ethylene released during transportation.

[0029] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] According to an embodiment of the present invention, an embodiment of a method for preserving fruits and vegetables in a cold storage is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 1 FIG. 1 is a flow chart of a method for preserving fruits and vegetables in a cold storage according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0033] Step S101, detecting the maturity of fruits and vegetables in each storage area in the cold storage;

[0034] Step S102, adjusting the cold storage temperature according to the maturity of fruits and vegetables;

[0035] Step S103, judging whether to transfer the fruits and vegetables in each storage area to a low-temperature storage area according to the maturity of the fruits and vegetables in the storage area; wherein a low-temperature storage area is provided in the cold storage, and the temperature of the low-temperature storage area is lower than the temperature of the cold storage.

[0036] This embodiment adjusts the temperature in the cold storage by real-time monitoring of the maturity of fruits and vegetables in the cold storage to inhibit the growth of ethylene and realize dynamic regulation of ethylene concentration. Fruits and vegetables with higher maturity are transferred to a low-temperature storage area with a lower temperature for low-temperature refrigeration. This achieves fine regulation of the quality of fruits and vegetables, maintains the best storage environment for fruits and vegetables, and reduces the loss of fruit and vegetable quality. By using automated equipment and computing systems, efficient monitoring and processing of cold chain fruits and vegetables is achieved, manual operations are reduced, and work efficiency is improved.

[0037] When detecting the maturity of fruits and vegetables in each storage area in the cold storage, the ethylene concentration of each storage area in the cold storage can be detected by an ethylene concentration sensor; wherein a sensor moving structure is arranged inside the cold storage to realize the movement of the ethylene concentration sensor; the maturity of fruits and vegetables in each storage area is determined according to the rate of change of the ethylene concentration in the storage area. The number and position of the ethylene concentration sensors and the sensor moving structure can be determined according to the area of ​​the cold storage, the number and position of the storage areas, and can ensure that each storage area can be detected by the ethylene concentration sensor. The sensor moving structure can be a slide rail. Based on the above preferred embodiment, the ethylene concentration of each storage area can be accurately and timely detected, rather than the ethylene concentration of the entire cold storage, and the temperature in the cold storage can be adjusted in time to achieve dynamic regulation of the ethylene concentration.

[0038] It should be noted that the maturity of fruits and vegetables in each storage area in the cold storage can be detected in real time or periodically, for example, once every 20 minutes and subsequent control plans can be executed.

[0039] The rate of change of ethylene concentration can characterize the maturity of fruits and vegetables. The maturity of fruits and vegetables in each storage area can be determined according to the rate of change of ethylene concentration in the storage area. This can be achieved by the following preferred implementation: based on the mapping relationship, the maturity of fruits and vegetables corresponding to the rate of change of ethylene concentration is determined; wherein, a mapping relationship between the rate of change of ethylene concentration V and the maturity of fruits and vegetables x is preset: V = g(x); wherein 0≤x≤10. Based on this, the maturity change of fruits and vegetables in each storage area can be accurately known, and the temperature of the cold storage can be accurately adjusted according to the maturity of fruits and vegetables. Fruits and vegetables with higher maturity can be transferred in time to better control the quality of fruits and vegetables.

[0040] When adjusting the cold storage temperature according to the maturity of fruits and vegetables, it can be achieved through the following preferred implementation: calculating the average maturity of fruits and vegetables in all storage areas; adjusting the cold storage temperature according to the average value, which can be achieved through the following formula:

[0041] T=x avg (T max -T min ) / 10+T min ; Where T is the cold storage temperature, x avg is the average maturity of fruits and vegetables in all storage areas, [T min , T max ] is the preset fruit and vegetable storage temperature range, and the temperature of the low temperature storage area is set to T min .

[0042] This embodiment adjusts the temperature in the cold storage according to the maturity of fruits and vegetables, which can inhibit the growth of ethylene and achieve dynamic regulation of ethylene concentration.

[0043] Fruits and vegetables with a higher degree of maturity need to be transferred in time to better control the quality of the fruits and vegetables. Based on this, this embodiment provides a preferred implementation method, that is, judging whether to transfer the fruits and vegetables in each storage area to the low-temperature storage area according to the maturity of the fruits and vegetables in the storage area, including: judging whether the maturity of the fruits and vegetables in each storage area exceeds a preset threshold; if exceeded, the fruits and vegetables in the storage area are transferred to the low-temperature storage area by a robotic arm; wherein a robotic arm moving structure is arranged inside the cold storage to realize the movement of the robotic arm. The number and position of the robotic arm and the robotic arm moving structure can be determined according to the area of ​​the cold storage, the number and position of the storage areas, and can ensure that the fruits and vegetables in each storage area can be picked up and placed by the robotic arm, and the robotic arm can also transfer the fruits and vegetables to the low-temperature storage area. The robotic arm moving structure can be a slide rail.

[0044] In addition to timely regulating the temperature of the cold storage to inhibit the release of ethylene, the embodiment of the present invention can also reduce the ethylene concentration by ventilation to avoid excessive ethylene release and accelerate the ripening of fruits and vegetables. Based on this, the embodiment provides a preferred implementation method, that is, detecting the ethylene concentration of each storage area in the cold storage; if the ethylene concentration of at least one storage area exceeds the preset concentration, the cold storage is ventilated.

[0045] When fruits and vegetables are just stored in the cold storage, it is necessary to set a suitable cold storage temperature. To this end, the initial cold storage temperature can be determined by the following preferred implementation: when fruits and vegetables are stored in the storage area of ​​the cold storage, the initial maturity of the storage area is determined according to the fruit and vegetable information of each storage area; wherein the fruit and vegetable information includes at least one of the following: fruit and vegetable type, fruit and vegetable quantity, picking time; the corresponding storage temperature is determined according to the initial maturity; the cold storage temperature is adjusted to the average storage temperature of all storage areas. Based on this, it can be ensured that the appropriate initial temperature of the cold storage can be determined according to the specific information of the fruits and vegetables when the fruits and vegetables are just stored, thereby ensuring the refrigeration effect of the fruits and vegetables.

[0046] This embodiment can solve the problem of manual inspection of the maturity of fruits and vegetables in cold chain transportation causing the work to be too cumbersome, solve the problem of ethylene released by mature fruits and vegetables in cold chain transportation ripening other unripe fruits and vegetables, and solve the problem of mismatch between the preservation temperature of fruits and vegetables during transportation and the maturity of fruits and vegetables.

[0047] Example 2

[0048] Figure 2 is a schematic diagram of the structure of a cold storage control device according to an embodiment of the present invention. Figure 2 As shown, the cold storage control device includes: one or more mechanical arms, arranged inside the warehouse, for picking up and placing fruits and vegetables in each storage area of ​​the warehouse; a mechanical arm moving structure adapted to the mechanical arm, for realizing the movement of the mechanical arm; one or more ethylene concentration sensors, arranged inside the warehouse, for detecting the ethylene concentration of each storage area of ​​the warehouse; a sensor moving structure adapted to the ethylene concentration sensor, for realizing the movement of the ethylene concentration sensor. The mechanical arm moving structure and the sensor moving structure can be slide rails.

[0049] The cold storage control device of this embodiment can implement the cold storage fruit and vegetable preservation method introduced above. The temperature in the cold storage is adjusted by real-time monitoring of the maturity of fruits and vegetables in the cold storage to inhibit the growth of ethylene and realize dynamic regulation of ethylene concentration. Fruits and vegetables with higher maturity are transferred to a low-temperature storage area with a lower temperature for low-temperature refrigeration. This enables fine regulation of the quality of fruits and vegetables, maintains the best storage environment for fruits and vegetables, and reduces the loss of fruit and vegetable quality. By using automated equipment and computing systems, efficient monitoring and processing of cold chain fruits and vegetables is achieved, manual operations are reduced, and work efficiency is improved.

[0050] The main components that the cold storage control device proposed in this embodiment relies on are:

[0051] An automatic pick-and-place robot with a slide rail is, for example, installed on the top of a warehouse, equipped with a slide rail to achieve horizontal movement, and a telescopic device is used to achieve vertical movement of the robot arm, responsible for picking up and placing fruits and vegetables (such as fruits) on both sides of the slide rail. A robot arm can be set for every two rows of storage areas, and a robot arm is also set for the remaining single row. In specific implementation, when there is only one robot arm, the robot arm moving structure can be set in the center of the top of the warehouse; when there are multiple robot arms, the robot arm moving structures can be evenly set on the top of the warehouse. Figure 2 The example of setting two horizontal rows of storage areas is used for illustration. In a specific implementation, the setting positions and numbers of the storage areas are not limited thereto.

[0052] The ethylene concentration sensor with a slide rail is similar to a robotic arm. It is equipped with a slide rail fixed in the middle of the warehouse in the vertical direction and equipped with a multi-axis robotic arm to achieve flexible movement. It is responsible for the concentration detection of fruits on both sides of the slide rail. An ethylene concentration sensor is set for every two rows of storage areas, and an ethylene concentration sensor is also set for the remaining single row. In specific implementation, when there is only one ethylene concentration sensor, the sensor moving structure can be set in the center of the top of the warehouse; when there are multiple ethylene concentration sensors, the sensor moving structure can be evenly set on the top of the warehouse.

[0053] The low-temperature storage area, as the area with the lowest temperature in the cold storage, can be set at the innermost part of the cold storage to ensure its lowest temperature; it can also be set on one side of the cold storage, with the same length as this side of the cold storage, so that each robotic arm can move to the low-temperature storage area. The low-temperature storage area uses insulation materials to isolate the influence of the external environment. There is an automatic door on the top, which opens automatically when the fruit is placed, and the internal temperature can be controlled independently. It also includes basic functional modules such as temperature control module, ventilation module and computing system. The functions of the functional modules can be set according to the air-conditioning unit of a general cold chain logistics vehicle.

[0054] This embodiment also proposes a cold chain transportation device, which includes the above-mentioned cold storage control device, so as to achieve the storage effect of fruits and vegetables in the cold storage during short-distance or long-distance cold chain transportation and ensure the quality of fruits and vegetables.

[0055] Example 3

[0056] This embodiment is introduced by keeping fruits fresh in cold storage. Figure 3 : is a work flow chart of fruit preservation in a cold storage according to an embodiment of the present invention, such as Figure 3 As shown, the process includes:

[0057] Step 1: Before the fruit is put into storage, the ethylene concentration curve of the fruit is measured by experiment, C=f(t), t is time, and the ethylene concentration growth rate curve is calculated, V=g(x), x is the ethylene maturity, ranging from 0 to 10. Set the ethylene high concentration threshold Ct and fruit storage temperature range [T min , T max ], taking apple as an example, the high concentration threshold of ethylene can be set at 10μL / L, and the storage temperature range can be 0℃-5℃.

[0058] The storage temperature corresponding to the ethylene maturity x is T = x (T max -T min ) / 10+T min .

[0059] The temperature of the low temperature storage area can be set to T min .

[0060] Step 2: When each basket (i.e. each storage area) of fruit enters the warehouse, the initial maturity x0 is set (it can be based on the picking time provided by the fruit farmer, 0 for just picked, and increases with the picking time, ranging from 0-10, or it can be determined based on the type and amount of fruits and vegetables). The system calculates its storage temperature T based on its initial maturity. In order to balance the preservation temperature of all fruits in the warehouse and achieve the best preservation effect, after all fruits are stored, the warehouse temperature is adjusted to the average value T of the preservation temperature T of all fruits. avg . Set the low temperature storage area temperature to T min , in order to inhibit fruit ripening to the greatest extent possible.

[0061] Step 3: Periodically (for example, every 20 minutes) test the ethylene concentration of each basket of fruit in the cold storage:

[0062] (1) Calculate the growth rate V of ethylene concentration to determine the maturity of the fruit. Suppose the current ethylene concentration is C and the last measured ethylene concentration is C. L , then the growth rate V = (CL-C) / 20, and the ethylene concentration growth rate curve V = g(x) is determined by the growth rate V, and the maturity x of the basket of fruits is obtained. When the maturity of the basket of fruits is greater than the preset threshold (for example, 7), the basket of fruits is considered to be too mature, and the measured data and the location information of the basket of fruits are recorded. After the end of this cycle detection, the over-mature fruits are sent to the low-temperature storage area using a robotic arm to prevent the ethylene released from them from affecting other fruits.

[0063] (2) Determine whether the current ethylene concentration C is greater than the set high concentration threshold. When the ethylene concentration C of a basket of fruit is greater than the preset concentration (e.g., the high concentration threshold C t ), after the current cycle test is completed, the ethylene concentration in the warehouse is reduced by ventilation. In order to avoid the change of ethylene concentration after ventilation affecting subsequent measurements, the ethylene concentration is measured again immediately, covering the currently measured ethylene concentration, as the basis for calculating the ethylene concentration growth rate next time.

[0064] Step 4: Finally, after all the steps in a cycle are completed, since the number of fruits may change, resulting in a change in the average maturity, the average maturity x of all fruits still in the cold storage is recalculated. avg The corresponding temperature in the warehouse is adjusted according to the average maturity:

[0065] T=x avg (T max -T min ) / 10+T min ; Where T is the cold storage temperature, x avg It is the average maturity of fruits and vegetables in all storage areas.

[0066] This embodiment provides a preservation and temperature control solution for cold chain transported fruits. The ethylene concentration of each basket of fruits in the cold storage is automatically detected by a movable sensor, and the ethylene concentration is dynamically regulated. The degree of maturity of the fruit is determined by calculating the growth rate of the ethylene concentration, and the storage temperature is automatically adjusted according to the maturity of the fruit, and over-ripe fruits are stored in low temperature refrigeration. This method keeps the fruit in the best storage environment and reduces the loss of fruit quality.
