Description

Technical Field

[0001] The present application relates to the technical field of cold chain equipment, and in particular to a cold chain equipment control method, system and intelligent terminal. Background Art

[0002] Cold chain equipment refers to equipment used to keep temperature-sensitive goods such as medicines, vaccines, biological products, and food at the required low temperature environment during transportation and storage. These equipment are essential to ensuring the quality and safety of products throughout the supply chain, especially in the pharmaceutical and food industries.

[0003] In the relevant technology, refrigerated trucks in cold chain equipment are crucial as transportation tools. Refrigerated trucks are specially designed to transport goods that need to be kept within a specific temperature range. They are usually equipped with a refrigeration system. Before loading the goods, the refrigeration system needs to be started to pre-cool the compartment of the refrigerated truck, and then the goods are correctly stacked in the compartment. Finally, the refrigeration system is controlled to keep the temperature in the compartment at the temperature required by the goods, thereby ensuring the quality of the goods during transportation.

[0004] Regarding the above-mentioned related technologies, when multiple types of goods are placed in the compartment of a refrigerated truck at the same time, if the storage temperatures required for the goods do not overlap, the refrigerated truck will not be able to effectively store the multiple types of goods at the same time, resulting in poor use of the refrigerated truck. There is still room for improvement. Summary of the Invention

[0005] In order to effectively preserve multiple goods at the same time and improve the use effect of refrigerated trucks, the present application provides a cold chain equipment control method, system and intelligent terminal.

[0007] By adopting the above technical solution, when it is determined that the cargo loading status meets the requirements for the cargo type change status, it indicates that the compartment of the refrigerated truck needs to be loaded with different cargoes. Therefore, the partitioning device is controlled to partition the compartment, thereby realizing cargo isolation, and then the refrigeration device is controlled to refrigerate and preserve the cargo in the compartment separately at a suitable temperature, thereby effectively preserving multiple cargoes at the same time to improve the use effect of the refrigerated truck.

[0008] Optionally, the step of controlling a preset partitioning device to partition a preset carriage to achieve cargo isolation includes: Obtain the storage temperature of the goods; Analyze the storage temperature to determine if there is a preset crossover temperature; If there is a cross temperature, the partition device is controlled to standby; If there is no cross temperature, the partitioning device is controlled to partition the carriage to achieve cargo isolation.

[0009] By adopting the above technical solution, when it is determined that there are multiple types of goods, after analyzing the storage temperatures of the goods, it is determined whether the storage temperatures of the multiple types of goods have cross-temperatures. If so, it indicates that no partitioning is required. If not, it indicates that the storage temperatures of the goods are different. Therefore, the partitioning device is controlled to partition the carriage to achieve cargo isolation, thereby improving the storage effect of the goods.

[0016] Optionally, the step of controlling the refrigeration device to refrigerate and preserve the cargo in the carriage according to a preset unified refrigeration method includes: Get the cargo type; Determine whether the cargo type meets the requirements of the preset single cargo type; If it meets the requirements, a single storage temperature is obtained; The refrigeration device is controlled according to a single storage temperature to refrigerate the goods in the carriage; If not, obtain the shared storage temperature; The refrigeration device is controlled according to the shared storage temperature to refrigerate the goods in the carriage.

[0017] By adopting the above technical solution, when it is determined that the carriage is not partitioned, if there is only one type of cargo, the cargo in the carriage is refrigerated and preserved according to a single storage temperature control refrigeration device; if there are multiple types of cargo, the cargo in the carriage is refrigerated and preserved according to a shared storage temperature control refrigeration device, thereby improving the refrigeration and preservation effect of the cargo.

[0018] Optionally, after controlling the preset refrigeration device to refrigerate and preserve the goods in the compartment according to the loading completion trigger signal, an auxiliary preservation step is further included, and the specific steps include: Obtain cargo information and corresponding cargo storage location; Determine whether the cargo information meets the preset requirements for bottom refrigerated cargo; If not, the preset auxiliary storage device is controlled to be on standby; If it meets the requirements, the preset auxiliary storage device auxiliary refrigeration device is controlled according to the storage position of the cargo to refrigerate the cargo in the compartment.

[0020] Optionally, the step of controlling a preset auxiliary storage device to assist a refrigeration device in refrigerating and preserving the cargo in the compartment according to the cargo storage position includes: Determine the start-up auxiliary device sequence number based on the cargo storage location and the preset position auxiliary relationship; According to the auxiliary device activation sequence number and the preset interval sequence number signal, a part of the auxiliary storage devices is controlled to lift the cargo to form an air duct for cold air to contact the bottom of the cargo; Get the replacement trigger signal; According to the replacement trigger signal and the start-up auxiliary device sequence number, another part of the auxiliary storage device is controlled to lift the cargo to form an air duct for cold air to contact the bottom of the cargo.

When it is determined that the cargo loading status meets the requirements of the cargo type change status, it indicates that the compartment of the refrigerated truck needs to be loaded with different cargoes. Therefore, the partitioning device is controlled to partition the compartment to achieve cargo isolation, and then the refrigeration device is controlled to refrigerate and preserve the cargo in the compartment separately at a suitable temperature, thereby effectively preserving multiple cargoes at the same time to improve the use effect of the refrigerated truck.

[0024] In a third aspect, the present application provides a smart terminal that adopts the following technical solution: An intelligent terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute a cold chain equipment control method as described in any one of the above items.

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figures 1 to 8 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0036] An embodiment of the present application discloses a cold chain equipment control method, specifically disclosing a processing terminal, a partitioning device and a refrigeration device. The processing terminal is respectively connected to the partitioning device and the refrigeration device through data wires to realize data interaction. When the processing terminal receives a loading trigger signal of the goods, the processing terminal responds to the loading trigger signal to collect a cargo loading image, thereby determining the cargo loading status after analyzing the cargo loading image, and judging whether the cargo loading status meets the requirements of the cargo type change status. If not, it indicates that the loaded cargo type has not changed, so the cargo loading image continues to be collected, thereby continuously monitoring the cargo status; if it meets the requirements, it indicates that the loaded cargo type has changed, so the partitioning device is controlled to partition the carriage to achieve cargo isolation. After detecting the loading completion trigger signal, the processing terminal controls the refrigeration device to refrigerate and preserve the cargo in the carriage, thereby ensuring that all cargo can be effectively preserved and improving the preservation effect of the cargo.

[0037] Reference Figure 1 , the embodiment of the present application discloses a cold chain equipment control method, comprising the following steps: Step S100: Obtain a loading trigger signal for a preset cargo.

[0038] The cargo refers to goods that require refrigerated transportation, including food, medicine, biological products, and cosmetics. The loading trigger signal refers to a trigger signal for starting to load the cargo into the compartment of the refrigerated truck, and is input by an operator into the processing terminal.

[0039] Step S101: Acquire a cargo loading image based on a loading trigger signal.

[0040] When the processing terminal receives the loading trigger signal, the processing terminal responds to the loading trigger signal to detect the cargo loading image, providing data support for subsequent determination of the cargo status.

[0041] The cargo loading image refers to the image of the cargo that personnel are about to load on the carriage, which is captured by the camera installed on the carriage controlled by the processing terminal.

[0042] Step S102: Analyze the cargo loading image to determine the cargo loading status.

[0043] Among them, the cargo loading status refers to the type status before and after the cargo is loaded. The processing terminal performs image recognition on the cargo loading images collected before and after according to the trained convolutional neural network to obtain the types of the cargo before and after. The types of the cargo before and after are then compared. If the types are consistent, it is determined that the cargo type has not changed to the cargo loading status. If the types are inconsistent, it is determined that the cargo type has changed to the cargo loading status.

[0044] Step S103: Determine whether the cargo loading status meets the preset cargo type change status requirement.

[0045] Among them, the cargo type change status refers to the status in which the cargo type has changed, and the requirements for the cargo type change status refer to consistency with the cargo type change status.

[0046] The processing terminal determines whether the cargo loading status is consistent with the cargo type change status, thereby determining whether the cargo loaded before and after has changed.

[0047] Step S1031: If not, continue to obtain cargo loading images for cyclic judgment.

[0048] If the processing terminal determines that the cargo loading status is inconsistent with the cargo type change status, it indicates that the cargo loaded before and after has not changed, so the cargo transfer image continues to be collected, thereby continuing to pay attention to changes in cargo types.

[0049] Step S1032: If it is met, the preset partitioning device is controlled to partition the preset carriage to achieve cargo isolation.

[0050] Among them, if the processing terminal determines that the cargo loading status is consistent with the cargo type change status, it means that the cargo loaded before and after has changed, and it may be necessary to partition the cargo to ensure that the cargo is stored at different temperatures. Therefore, the partitioning device is controlled to partition the carriage to achieve cargo isolation. For specific methods, refer to Figure 2 steps.

[0051] A partitioning device is a device used to divide the compartment of a refrigerated truck. It consists of a linear module, partition plates, and a tilting motor located along the length of the compartment. The linear module controls the movement of the partition plates along the length of the compartment, thereby partitioning cargo at different locations. The tilting motor controls the flipping of the partition plates, either perpendicular to the ground to create a partition or parallel to the ground to release the partition. A compartment is the compartment of a refrigerated truck used to store refrigerated cargo.

[0052] Step S104: Obtain a loading completion trigger signal.

[0053] The loading completion trigger signal refers to a trigger signal indicating that the cargo has been loaded onto the refrigerated truck, and is input into the processing terminal by an operator.

[0054] Step S105: controlling a preset refrigeration device to refrigerate and preserve the goods in the compartment according to a loading completion trigger signal.

[0055] When the processing terminal receives the loading completion trigger signal, the processing terminal responds to the loading completion trigger signal, thereby controlling the refrigeration device to refrigerate the goods in the compartment. For specific methods, refer to Figure 5 steps.

[0056] The refrigeration device refers to the refrigeration system on the refrigerated truck. In the embodiment of the present application, the refrigeration device adopts a mechanical refrigerator, which realizes cooling through the refrigerator of components such as a compressor, a condenser, and an evaporator.

[0057] Reference Figure 2 The steps of controlling the preset partitioning device to partition the preset carriage to achieve cargo isolation include: Step S200: Obtain the storage temperature of the goods.

[0058] Among them, the storage temperature refers to the refrigeration temperature range of different goods in the carriage, which is obtained by the operator entering the processing terminal.

[0059] Step S201: Analyze the storage temperature to determine whether there is a preset crossover temperature.

[0060] Cross-temperatures refer to temperature ranges that overlap. The processing terminal compares the storage temperatures of the goods to determine if there are any cross-temperatures between the storage temperatures of different goods, providing data support for subsequent decisions on zoning.

[0061] Step S2011: If there is a cross temperature, control the partition device to standby.

[0062] Among them, if the processing terminal determines that the storage temperatures of different goods have cross-temperatures, it means that although there are multiple goods in the carriage, there is a unified refrigeration temperature, so there is no need to partition the carriage, and the partition device can continue to be controlled to standby.

[0063] Step S2012: If there is no cross temperature, the partitioning device is controlled to partition the carriage to achieve cargo isolation.

[0064] Among them, if the processing terminal determines that there is no cross temperature between the storage temperatures of different goods, it means that there are multiple goods with different storage temperatures in the compartment, and partitioning is required to ensure the refrigeration effect. Therefore, the partitioning device is controlled to partition the compartment to achieve cargo isolation. The specific method is referred to Figure 3 steps.

[0065] Reference Figure 3 The steps of controlling the partitioning device to partition the carriage to achieve cargo isolation include: Step S300: Acquire a cargo compartment loading image.

[0066] Among them, the carriage loading image refers to the image of the cargo in the carriage, which is captured by the camera in the carriage and sent to the processing terminal.

[0067] Step S301: Analyze the carriage loading image and the preset coordinate system to determine the location of the cargo.

[0068] The coordinate system refers to a rectangular coordinate system established with a corner of the carriage as the origin, the length of the carriage as the Y-axis, and the width of the carriage as the X-axis. The cargo location refers to the coordinate position of the cargo within the carriage. The processing terminal maps the coordinate system onto the carriage loading image, thereby identifying the specific location coordinates of the cargo within the carriage.

[0069] Step S302: Determine the partition location according to the cargo location and the preset location partition relationship.

[0070] The location partition relationship refers to the distance relationship between the cargo location and the partition location, which is usually expressed as adding the set partition distance to the maximum Y coordinate of the cargo location.

[0071] The partition position refers to the location of the partition in the carriage. It only has the Y-axis coordinate. The processing terminal identifies the maximum value of the Y-axis coordinate corresponding to the cargo position, and adds the distance corresponding to the position partition relationship on the basis of the maximum value to obtain the partition position.

[0072] Step S303: Control the partitioning device to move to the partitioning position and obtain a movement completion trigger signal.

[0073] Among them, after determining the partition position, the processing terminal controls the partition device to move to the partition position and detects the movement completion trigger signal, thereby preparing for the subsequent flipping of the partition partition to isolate the goods.

[0074] The movement completion trigger signal refers to the trigger signal when the partitioning device moves to the partitioning position. The partitioning device detects the moving distance in real time, and outputs the movement completion trigger signal when it determines that the moving distance is equal to the distance from the original position to the partitioning position.

[0075] Step S304: Control the partitioning device to partition the carriage according to the movement completion trigger signal.

[0076] When the processing terminal receives a movement completion trigger signal, the processing terminal responds to the movement completion trigger signal, thereby controlling the partitioning device to partition the carriage to achieve precise isolation of the goods.

[0077] Reference Figure 4 The step of controlling the partitioning device to partition the carriage according to the movement completion trigger signal includes: Step S400: analyzing the storage temperature according to the movement completion trigger signal to determine a first cooling temperature and a second cooling temperature.

[0078] When the processing terminal receives the movement completion trigger signal, the processing terminal first analyzes the storage temperature and determines the first cooling temperature and the second cooling temperature, providing data support for subsequent determination of how to control the partition device.

[0079] The first refrigeration temperature refers to the refrigerated temperature range of the goods located within the partition partition, and the second refrigeration temperature refers to the refrigerated temperature range of the goods located outside the partition partition, which is called by the processing terminal according to the type of stored goods and the storage temperature.

[0080] Step S401: Analyze the first refrigeration temperature and the second refrigeration temperature to determine a storage temperature difference.

[0081] The stored temperature difference refers to the minimum temperature difference between the first refrigeration temperature and the second refrigeration temperature, which is obtained by calculating the absolute value of the difference between the first refrigeration temperature and the second refrigeration temperature and selecting the minimum absolute value of the difference.

[0082] Step S402: Analyze the stored temperature difference and the preset partition temperature difference relationship to determine the number of starting devices.

[0083] Among them, the partition temperature difference relationship refers to the isolation temperature difference of a single partition partition. The specific value is determined by the operator after conducting a temperature isolation test based on the actual partition partition.

[0084] The number of starting devices refers to the number of flip partition partitions, which is obtained by calculating the quotient between the stored temperature difference and the partition temperature relationship by the processing terminal. If it is less than 1, it will be calculated as 1.

[0085] Step S403: Control the partitioning device to activate the number of devices to flip the preset partitioning partitions to partition the carriage.

[0086] Among them, after determining the number of starting devices, the flip motor in the partition device is controlled to flip the partition partition corresponding to the number of starting devices, so that the partition partition divides the carriage into partitions, ensuring that the storage temperature of the goods on both sides of the partition does not affect each other.

[0087] Reference Figure 5 The steps of controlling a preset refrigeration device to refrigerate and preserve the cargo in the carriage according to a loading completion trigger signal include: Step S500: Acquire the carriage loading status of the carriage.

[0088] Among them, the carriage loading status refers to the status of the cargo being loaded in the carriage, including unified loading and partitioned loading. It is determined by the processing terminal whether the partitioning device is started. If it is started, the partitioned loading is determined to be the carriage loading status. If it is not started, the unified loading is determined to be the carriage loading status.

[0089] Step S501: Determine whether the carriage loading status meets the requirements of the preset zone loading status.

[0090] Among them, the partition loading state refers to the state in which the goods in the carriage are loaded in partitions, and the requirements for the partition loading state refer to being consistent with the partition loading state.

[0091] The processing terminal determines whether the loading status of the carriage is consistent with the loading status of the partition, thereby determining whether the carriage is partitioned, and providing data support for subsequent control of the refrigeration device.

[0092] Step S5011: If not, the refrigeration device is controlled according to a preset unified refrigeration method to refrigerate and preserve the goods in the compartment.

[0093] Among them, if the processing terminal determines that the loading status of the carriage is inconsistent with the loading status of the partition, it means that there is no partition loading in the carriage, but unified loading. Therefore, the refrigeration device is controlled according to the unified refrigeration method to refrigerate the goods in the carriage. The specific method is referred to Figure 6 steps.

[0094] The unified refrigeration method refers to the method of refrigerating and preserving the goods in the compartment at the same temperature. For specific methods, please refer to Figure 6 steps.

[0095] Step S5012: If it meets the requirements, the cargo loading location and the corresponding cargo storage temperature are obtained.

[0096] Among them, if the processing terminal determines that the loading status of the carriage is consistent with the partition loading status, it means that the carriage is loaded in partitions, so partition refrigeration is required, so as to detect the cargo loading position and the corresponding cargo storage temperature, and provide data support for the subsequent control of the refrigeration device.

[0097] The cargo loading position refers to the location of the cargo within the vehicle compartment, which is essentially the same as the cargo position in step S301 and is not further described here. The cargo storage temperature refers to the storage temperature of the cargo at the cargo loading position, which is essentially the same as the storage temperature in step S200. The processing terminal selects the maximum or minimum value of the temperature range as needed, specifically comparing the temperature ranges of adjacent cargo. For example, if the temperature of an adjacent cargo is higher, the temperature of that cargo is set to the highest temperature, while the temperature of the adjacent cargo is set to the lowest temperature.

[0098] Step S502: determining the activation device sequence number according to the cargo loading position and the preset position device relationship.

[0099] Among them, the position-device relationship refers to the correspondence between the position in the car and the serial number of the refrigeration device. The operator forms a mapping table by matching the installation positions of different refrigeration devices in the actual car with the serial numbers of the refrigeration devices one by one.

[0100] The starting device serial number refers to the serial number of the refrigeration device that refrigerates the cargo at the cargo loading position, and is obtained by searching the mapping table corresponding to the position-device relationship according to the cargo loading position by the processing terminal.

[0101] Step S503: controlling the corresponding refrigeration device according to the start-up device sequence number to refrigerate the cargo in the compartment at the cargo storage temperature.

[0102] Among them, after determining the starting device serial number, the refrigeration device corresponding to the starting device serial number is controlled to refrigerate and preserve the cargo in the compartment at the cargo preservation temperature, thereby ensuring that the cargo is effectively preserved.

[0103] Reference Figure 6 The steps of controlling the refrigeration device to refrigerate and preserve the cargo in the carriage according to a preset unified refrigeration method include: Step S600: Obtain the cargo type.

[0104] The cargo type refers to the type of cargo loaded in the carriage, which is input into the processing terminal by the operator.

[0105] Step S601: Determine whether the cargo type meets the requirements of a preset single cargo type.

[0106] Among them, a single cargo type means that there is only one type of cargo in the carriage, and the requirements for a single cargo type refer to being consistent with a single cargo type.

[0107] The processing terminal determines whether the cargo type is consistent with a single cargo type, thereby determining whether multiple cargoes are loaded in the carriage.

[0108] Step S6011: If it meets the requirements, a single storage temperature is obtained.

[0109] Among them, if the processing terminal determines that the cargo type is consistent with a single cargo type, it means that there is only one type of cargo in the carriage, so a single storage temperature is obtained to provide data support for the subsequent control of the refrigeration device.

[0110] Single storage temperature refers to the storage temperature of a type of goods, which is obtained by the operator inputting the storage temperature of the goods into the processing terminal.

[0111] Step S60111: Control the refrigeration device to refrigerate the cargo in the vehicle compartment according to a single storage temperature.

[0112] Among them, after determining the single storage temperature, the processing terminal controls the refrigeration device to refrigerate and store the goods in the carriage at the single storage temperature, thereby ensuring the safety and quality of the goods during transportation.

[0113] Step S6012: If not, obtain the shared storage temperature.

[0114] Among them, if the processing terminal determines that the cargo type is inconsistent with a single cargo type, it indicates that there are multiple types of cargo in the carriage, so the shared storage temperature is detected to provide data support for the subsequent control of the refrigeration device.

[0115] The shared storage temperature refers to the temperature at which all goods can be stored. The operator inputs the storage temperature of the goods into the processing terminal, which identifies the intersection of the storage temperatures and selects the middle value of the intersection as the shared storage temperature.

[0116] Step S60121: Control the refrigeration device to refrigerate the cargo in the compartment according to the shared storage temperature.

[0117] Among them, after determining the shared storage temperature, the processing terminal controls the refrigeration device to refrigerate and preserve the goods in the carriage at the shared storage temperature, thereby ensuring the safety and quality of various goods during transportation.

[0118] Reference Figure 7 After controlling the preset refrigeration device to refrigerate the cargo in the compartment according to the loading completion trigger signal, the auxiliary preservation step is also included. The specific steps include: Step S700: Obtain cargo information and the corresponding cargo storage location.

[0119] Cargo information refers to the cargo's temperature sensitivity, which can be either high or low. For example, medicines, vaccines, and high-value foods are very sensitive to temperature changes, while canned goods and dry goods are less sensitive. This information is input by the operator into the processing terminal. Cargo storage location refers to the storage location of the cargo within the carriage corresponding to the cargo information. This is essentially the same as the cargo location in step S301 and is not further described here.

[0120] Step S701: Determine whether the cargo information meets the preset requirements for bottom refrigerated cargo.

[0121] Among them, bottom refrigerated cargo refers to cargo that requires bottom refrigeration to ensure uniform temperature, such as medicines, vaccines, high-value foods and other cargo that are very sensitive to temperature changes. The requirements for bottom refrigerated cargo refer to cargo that exists in bottom refrigerated cargo.

[0122] The processing terminal determines whether the cargo corresponding to the cargo information exists in the bottom refrigeration cargo, thereby determining whether bottom refrigeration is required.

[0123] Step S7011: If not, control the preset auxiliary storage device to standby.

[0124] If the processing terminal determines that the cargo corresponding to the cargo information does not exist in the bottom refrigerated cargo, it indicates that the temperature sensitivity of the cargo in the compartment is low and the bottom does not need to be refrigerated, so the auxiliary storage device can be controlled to standby.

[0125] The auxiliary preservation device refers to a device that assists the refrigeration device in cooling the bottom of the cargo, and includes a lifting rod and a support rod. The support rod is used to carry the cargo, and the lifting rod is used to raise the support rod, thereby forming an air duct at the bottom of the cargo to supply cold air to contact the bottom of the cargo. The support rod is arranged along the width of the car body, and multiple support rods are arranged side by side. Adjacent support rods are controlled by different lifting rods, and the interval support rods are controlled by the same lifting rod.

[0126] Step S7012: If the conditions are met, the preset auxiliary storage device auxiliary refrigeration device is controlled according to the cargo storage position to refrigerate the cargo in the compartment.

[0127] Among them, if the processing terminal determines that the cargo corresponding to the cargo information exists in the bottom refrigerated cargo, it means that the cargo in the compartment needs to be refrigerated at the bottom to ensure uniform temperature. Therefore, the corresponding auxiliary storage device is controlled according to the storage position of the cargo to refrigerate the cargo in the compartment. The specific method is referred to Figure 8 steps.

[0128] Reference Figure 8 The steps of controlling the preset auxiliary storage device to assist the refrigeration device to refrigerate the cargo in the compartment according to the cargo storage position include: Step S800: determining the activation auxiliary device sequence number according to the cargo storage location and a preset position auxiliary relationship.

[0129] Among them, the position auxiliary relationship refers to the correspondence between the position in the car and the serial number of the auxiliary device. The operator forms a mapping table by matching the actual position in the car with the serial number of the auxiliary device at that position one by one.

[0130] The activation auxiliary device serial number refers to the serial number of the auxiliary storage device that needs to be activated, and is obtained by searching in the mapping table corresponding to the position auxiliary relationship according to the storage location of the goods by the processing terminal.

[0131] Step S801: According to the auxiliary device activation sequence number and the preset interval sequence number signal, a part of the auxiliary storage devices is controlled to lift the cargo to form an air duct for cold air to contact the bottom of the cargo.

[0132] Among them, after the processing terminal determines the start-up auxiliary device serial number, it controls the auxiliary storage device corresponding to the start-up auxiliary device serial number according to the interval serial number signal to lift the goods in the form of interval lifting, thereby forming an air duct at the bottom of the goods, so that cold air can contact the bottom of the goods from the air duct, ensuring uniform refrigeration temperature of the goods.

[0133] The interval sequence number signal refers to a signal that controls the auxiliary storage device to be started to be raised in an interval raising manner, and is stored in the processing terminal by the operator.

[0134] Step S802: Acquire a replacement trigger signal.

[0135] Among them, the replacement trigger signal refers to the signal for the auxiliary storage device to replace the adjacent support rod for lifting. The processing terminal counts the support time and outputs the replacement trigger signal after determining that the support time reaches the replacement time.

[0136] Step S803: According to the replacement trigger signal and the auxiliary device start-up sequence number, another part of the auxiliary storage device is controlled to lift the cargo to form an air duct for cold air to contact the bottom of the cargo.

[0137] Among them, after receiving the replacement trigger signal, the processing terminal responds to the replacement trigger signal, thereby controlling the start-up of another part of the auxiliary storage device corresponding to the auxiliary device serial number to lift the goods, while the auxiliary storage device of the previous part is lowered, thereby changing the position of the air duct to evenly cool the goods.
