[0002] With the advancement of urbanization, a large urban population has emerged. However, urban residents are unable to sell their agricultural products themselves and need to transport them from the production areas to the cities through cold chain logistics. On the other hand, with the rapid rise of e-commerce, the originally bulk and large-scale cold chain transportation is shifting towards fragmented and high-frequency scattered transportation, thus significantly increasing the frequency of demand for cold chain logistics.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0059] Because current cold chain systems are ineffective at preserving certain products requiring freshness, high spoilage rates are common. Therefore, this application provides a preservation control method, apparatus, electronic device, and preservation system.
[0060] This application provides a method for controlling food preservation. This method can be applied to a cold storage device or a terminal device. The cold storage device or the terminal device can receive information from a food preservation basket device. For example, the food preservation basket device can refer to a smart fruit preservation basket, a smart vegetable preservation basket, etc., the cold storage device can refer to a mobile smart warehousing system or a non-mobile smart warehousing system, etc., and the terminal device can refer to a smart vending system at the sales end, etc. The food preservation basket device has a first space, the cold storage device has a second space, and the terminal device has a third space.
[0061] A preservation basket device can be the smallest unit for storing and preserving fresh objects. It can be placed in a cold storage device or a terminal device according to the storage and sales needs of the fresh objects. The preservation basket device, the cold storage device, and the terminal device can form a preservation system, realizing that from the harvesting site, storage site, transportation to the sales end, there is an intelligent system (i.e., cold storage device or terminal device) communicating with the preservation basket device.
[0062] like Figure 1As shown, the preservation basket device includes: an information storage module for storing object information of the objects to be preserved in the first space; a first temperature and humidity acquisition module for collecting temperature and humidity information in the first space; a weight acquisition module for collecting weight information of the objects to be preserved in the first space; a first communication module for communicating with the preservation warehouse device and the terminal device; and a timing module for recording the actual preservation time of the preservation basket device from the moment of activation.
[0063] For example, at the harvesting site, the fruit is first identified using image recognition technology. The identification module transmits the identified information to the preservation crate device. This information includes details such as category, size, harvesting location, and time. This identification information is stored in the information storage module of the preservation crate device. A first temperature and humidity acquisition module (e.g., a temperature and humidity sensor) senses the temperature and humidity information within the first space of the preservation crate device. A weight sensor senses the weight of the fruit within the first space of the preservation crate device. A timing module starts timing after the preservation crate device is activated, providing information on the preservation duration. The communication module communicates with fixed warehouses (i.e., immovable storage systems), mobile storage systems during transportation (e.g., refrigerated trucks), and smart vending systems, allowing them to obtain the identification information, temperature and humidity information, and weight information from the preservation crate device.
[0064] like Figure 2 As shown, the cold storage equipment includes: a first database module for storing object information, target preservation temperature, and target preservation humidity corresponding to the objects to be preserved in the first space; a second temperature and humidity acquisition module for collecting temperature and humidity information in the second space; a second communication module for communicating with the cold storage basket equipment; a first refrigeration and humidification module for refrigerating and humidifying the second space; a first early warning module for issuing a preservation warning based on the actual preservation time and the target preservation time corresponding to the object information, target preservation temperature, and target preservation humidity; and a geolocation module for collecting the current location of the cold storage equipment.
[0065] For example, during storage and transportation using the refrigerated crate equipment, the crate carrying the fruit and its information can be placed into a (non-)movable cold storage facility, such as a cold storage room, as needed. The communication module allows the cold storage facility to retrieve information from the crate, such as food type, size, harvest location, time, weight, temperature, and humidity. Through a fruit category query and comparison database module, empirical data can be obtained. For instance, the optimal target preservation temperature and humidity for this type of fruit can be obtained, and the refrigeration and humidification modules can be controlled accordingly; the unit cooling and water volume required for the fruit to move from its current temperature and humidity to the optimal temperature and humidity can be obtained, and combined with the total weight, the estimated total cooling and water volume required can be calculated; the preservation time under empirical temperature and humidity (i.e., the estimated number of days of preservation under the optimal environment after preservation) can be obtained, and combined with the harvest time recorded by the harvesting time and timing module, preservation warning information can be provided, such as how much longer the fruit will expire. The cold storage facility also has a built-in geolocation module that can display the current geographical location of the cold storage facility. The first early warning module displays environmental parameters, control parameters, time parameters (including stored time and expiration time) and geographical location parameters during storage and transportation, so that nearby managers can query them. It can also be remotely queried by managers far away from the cold storage through the communication module, providing a reference for product distribution.
[0066] like Figure 3 As shown, the terminal device includes: a first database module for storing object information, target preservation temperature, and target preservation humidity corresponding to the object to be preserved in the first space; a storage location module for storing the placement location in a third space corresponding to the object information; a second temperature and humidity acquisition module for collecting temperature and humidity information in the third space; a third communication module for communicating with the preservation basket device; a third cooling and humidification module for cooling and humidifying the third space; and a second early warning module for providing preservation early warning based on the actual preservation time and the target preservation time corresponding to the object information, target preservation temperature, and target preservation humidity.
[0067] When the refrigerated crate equipment reaches the terminal equipment, the terminal equipment queries the equipment's information via its communication module, obtaining the product category and suitable refrigeration and humidification conditions. Based on historical placement data from the terminal system's storage location module, it instructs the fruit to be placed in the terminal equipment. The terminal equipment also queries the current preservation time and formulates a sales strategy based on the product's condition. After communicating with the terminal equipment, the refrigerated crate equipment places the fruit from its crate into the terminal equipment's warehouse. The crate equipment can then be retrieved with the vehicle. After recording this transaction, the data within the crate equipment can be cleared for future use.
[0068] Traditional cold chain logistics relies primarily on hardware such as warehouses and refrigerated trucks, lacking information systems for warehousing and transportation management. This fragmentation disrupts the originally integrated logistics chain, impacting product quality and timeliness, and leading to high spoilage rates and costs. This application addresses this by incorporating information technology into the preservation basket equipment used to hold fresh-keeping objects. First, front-end pattern recognition identifies the type of object to be preserved, generating identification information (including category, size, location, and time), which is then transmitted to the preservation basket equipment. The equipment also has a timing module that records preservation time, providing a reference for preservation. The preservation basket equipment can independently formulate refrigeration and humidification strategies based on preservation control methods, or receive refrigeration and humidification strategies formulated by other equipment or terminal devices based on preservation control methods. Then, within the (non-)movable preservation storage equipment, a geolocation module displays the storage and transportation location for easy querying. Product status can be viewed on a nearby screen or remotely queried via a communication module. Finally, at the terminal equipment at the sales end, the terminal system identifies the fruit information on the fruit basket, obtains the historical storage location, preservation strategy and preservation time, so that the end user can continuously monitor the status of the fruit. The smart fruit basket can also collect and clear the data for the next use.
[0069] The cold storage equipment or terminal equipment can also communicate with the smart fruit basket to obtain fruit information and formulate refrigeration and humidification strategies; by querying the database module, it can add experience data and weight to assist in the judgment, avoiding the problem of one-sided judgment by a single sensor.
[0070] Taking the refrigerated crate equipment as a smart fruit crate, the cold storage equipment as a warehousing system, and the terminal equipment as a terminal system as an example, the diagram illustrating the information transmission between the three is as follows: Figure 4 As shown.
[0071] In yet another embodiment of this application, as Figure 5 As shown, the preservation control method includes:
[0072] Step S101: Obtain object information of the object to be preserved in the first space and environmental information of the environment in which the object to be preserved is directly or indirectly located.
[0073] In this embodiment of the application, the object to be preserved can refer to products that need to be preserved, such as fruits, vegetables, seafood, etc. The object information includes: identification information obtained by identifying the object to be preserved (the identification information includes: object category, object size, acquisition location and acquisition time, etc.) and weight information, etc. The environmental information of the environment in which the object to be preserved is directly or indirectly located includes: environmental information within or near the first space, and environmental information of the second or third space in which the first space is located. The environmental information within or near the first space includes: temperature and humidity information within or near the first space (temperature and humidity information includes temperature information and humidity information). The environmental information of the second or third space in which the first space is located includes: size information of the second or third space, temperature and humidity information of the second or third space (temperature and humidity information includes temperature information and humidity information), etc.
[0074] When the preservation control method is applied to cold storage equipment or terminal equipment, the preservation basket equipment can communicate with the cold storage equipment or terminal equipment through the first communication module. It can query the identification information of the object to be preserved (including object category, object size, acquisition location and acquisition time, etc.) that it has pre-stored or identified itself, as well as the weight information and temperature and humidity information that it has collected, and send the obtained object information and environmental information to the cold storage equipment or terminal equipment.
[0075] Step S102: Extract the weight information of the object to be preserved from the object information, wherein the weight information includes the total weight of the object to be preserved;
[0076] Step S103: Determine a cooling and humidification strategy based on the weight information and the environmental information;
[0077] During the implementation of this invention, the inventors discovered that when the weight of the object to be preserved is large, the heat emitted by respiration is greater, causing a difference between the actual temperature of the object to be preserved and the ambient temperature detected at a single location. This temperature difference can lead to poor product preservation and a high rate of product spoilage when the cooling and humidification control is based solely on the ambient temperature. Therefore, this application combines weight information and environmental information to determine the cooling and humidification strategy.
[0078] In this step, the corresponding cooling and humidification strategy can be retrieved from the pre-stored weight, environment, and strategy correspondence based on weight and environmental information.
[0079] In this embodiment of the application, the cooling and humidification strategy may refer to the control strategy for stopping or starting the compressor, air cooler, atomizer and atomizing fan in the second or third space where the first space is located.
[0080] Step S104: Cool and humidify the first space according to the cooling and humidification strategy.
[0081] After determining the refrigeration and humidification strategy, the refrigeration and humidification module of the food preservation basket equipment can be controlled to refrigerate and humidify the first space according to the control strategy for stopping or starting the compressor, air cooler, atomizer and atomizing fan in the refrigeration and humidification strategy.
[0082] This application embodiment determines the refrigeration and humidification strategy by combining the weight information of the object to be preserved with the environmental information of the environment in which the object is directly or indirectly located. It can take into account the impact of the heat emitted by the object's respiration on the ambient temperature, and avoid the situation where the refrigeration and humidification control is mismatched with the refrigeration and humidification amount required by the object due to ignoring the object's respiration. This makes the refrigeration and humidification control in the preservation basket equipment more matched with the actual refrigeration and humidification needs of the object, thereby improving the preservation effect of the object and reducing the spoilage rate of the object.
[0083] In another embodiment of this application, determining a cooling and humidification strategy based on the weight information and the environmental information includes:
[0084] Step S201: Obtain the target preservation temperature and target preservation humidity corresponding to the object to be preserved;
[0085] In this embodiment of the application, different objects to be preserved have different target preservation temperatures and target preservation humidity. The target preservation temperature is the most suitable temperature for the object to be preserved, and the target preservation humidity is the most suitable humidity for the object to be preserved.
[0086] Step S202: Based on the weight information, the target preservation temperature, the target preservation humidity, and the environmental information, determine the target cooling load consumed to adjust the temperature in the first space to the target preservation temperature;
[0087] In this step, the space size, ambient temperature, and ambient humidity of the second or third space where the first space is located can be extracted from the environmental information, as well as the current humidity and current temperature of the first space (the current humidity and current temperature reflect the current temperature and humidity of the object to be preserved); a temperature difference is determined based on the target preservation temperature and the current temperature, and a humidity difference is determined based on the target preservation humidity and the current humidity; the target cooling load consumed to adjust the temperature in the first space from the current temperature to the target preservation temperature is determined based on the space size, the weight information, the ambient temperature, the ambient humidity, the temperature difference, and the humidity difference.
[0088] In one embodiment of this application, a first correspondence relationship between space size, weight information, ambient temperature, ambient humidity, temperature difference, humidity difference, and cooling consumption can be preset. Based on the space size, weight information, ambient temperature, ambient humidity, temperature difference, and humidity difference in the first correspondence relationship, the corresponding cooling consumption is searched and used as the target cooling consumption.
[0089] Step S203: Based on the weight information, the target preservation temperature, the target preservation humidity, and the environmental information, determine the target water consumption required to adjust the humidity in the first space to the target preservation humidity.
[0090] In this step, the space size, ambient temperature, and ambient humidity of the second or third space where the first space is located can be extracted from the environmental information, as well as the current humidity and current temperature of the first space; a temperature difference is determined based on the target preservation temperature and the current temperature, and a humidity difference is determined based on the target preservation humidity and the current humidity; the target water consumption required to adjust the humidity in the first space from the current humidity to the target preservation humidity is determined based on the space size, the weight information, the ambient temperature, the ambient humidity, the temperature difference, and the humidity difference.
[0091] In one embodiment of this application, a second correspondence relationship between space size, weight information, ambient temperature, ambient humidity, temperature difference, humidity difference, and water consumption can be preset. Based on the space size, weight information, ambient temperature, ambient humidity, temperature difference, and humidity difference in the second correspondence relationship, the corresponding water consumption is found as the target water consumption.
[0092] The empirical values for these first and second correspondences need to be obtained through prior experiments, that is, the theoretical estimated total value of the database is obtained through experiments. For example, the optimal storage environment for a certain fruit is a temperature T and a humidity H. The current temperature of the fruit is T1 and the humidity is H1. Cooling and humidifying processes will consume cooling and moisture.
[0093] Experiments (or queries of existing databases) were conducted to determine the amount of cooling consumed when lowering the temperature of fruit of different weights in spaces of varying sizes, and the amount of water consumed when increasing humidity. Cooling consumption can be calculated using electricity consumption and energy efficiency ratio, while water consumption can be determined from the metering of the water containers. Multiple sets of data were collected to create a database. This can be understood as establishing a corresponding relationship:
[0094] The total cooling load C and total water consumption W satisfy f(C) = f(V,M,T0,H0,rT,rH), meaning the cooling load consumed is affected by the space size V, fruit weight M, current ambient temperature T0, current ambient humidity H0, the difference in degrees between T1 and the optimal T (rT), and the difference in degrees between H1 and the optimal H (rH). Water consumption f(W) = f(V,M,T0,H0,rT,rH) is also affected by the above variables. When creating the database, the respiration of the fruit needs to be considered; temperature and humidity sensors can be placed inside the fruit pile.
[0095] A database is a system that, given V, M, T0, H0, ΔT, and ΔH, can locate the corresponding cooling load C and water consumption W. When a certain weight of fruit is stored in a specific spatial environment, its corresponding cooling load and water consumption are already fixed values.
[0096] 1) The space size V is determined when the cold storage is established / refrigerated truck is determined / terminal system is established, and can be stored in the database module of (non)preservative storage equipment (e.g., (non)mobile cold storage) and terminal equipment.
[0097] 2) The total weight M is transmitted to the data processing module in the refrigeration and humidification module of the cold storage equipment and the terminal equipment through the weight sensor in each cold storage basket equipment, and the total weight M is calculated.
[0098] 3) The current ambient temperature T0 and current ambient humidity H0 are obtained by the temperature and humidity sensors of the cold storage equipment and terminal equipment.
[0099] 4) The optimal storage environment for a certain fruit, which is the optimal temperature T and the optimal humidity H, is also stored in the database module of the cold storage equipment and terminal equipment.
[0100] 5) The difference in degree between T1 and T_optimal, ΔT, and the difference in degree between H1 and H_optimal affect ΔH. T1 and H1 are transmitted to the data processing module in the refrigeration and humidification module of the cold storage equipment and the terminal equipment through the temperature and humidity sensors in each cold storage basket equipment, and the difference ΔT and ΔH are calculated. The total cooling capacity C and water consumption W are calculated by combining the above data.
[0101] Step S204: If the current temperature and humidity information of the second or third space where the first space is located meets the preset first temperature and humidity conditions, determine the cooling and humidification strategy based on the target cooling load and the target water consumption.
[0102] In this embodiment of the application, the cooling and humidification strategy is determined only when the current temperature and humidity information in the cold storage equipment or terminal equipment where the cold storage basket equipment is located meets the first temperature and humidity condition. The current temperature and humidity information of the second space or the third space includes: the temperature information and humidity information of the second space or the third space. The first temperature and humidity condition means that the temperature information of the second space or the third space meets the expected temperature and the humidity information of the second space or the third space meets the expected humidity.
[0103] Because the actual diffusion of cooling water is affected by the environmental conditions at the time, there will be some difference between the total value and the theoretical estimate in the database. In one embodiment of this application, a cooling and humidification strategy is determined based on the target cooling load and the target water consumption, including:
[0104] Step S301: Obtain the current temperature and humidity information of the first space, wherein the temperature and humidity information includes: the current humidity and current temperature of the first space;
[0105] Step S302: Obtain the actual water consumption and actual cooling consumption of the second or third space where the first space is located from the time the environmental information is obtained.
[0106] Step S303: Determine a cooling and humidification strategy based on the relationship between the temperature and humidity information and the preset second temperature and humidity conditions, the relationship between the actual water consumption and the target water consumption, and the relationship between the actual cooling consumption and the target cooling consumption.
[0107] In this step, if the temperature and humidity information meets the preset second temperature and humidity conditions, the actual water consumption does not reach the target water consumption, and the actual cooling consumption does not reach the target cooling consumption, the cooling and humidification strategy is determined to be a cooling and humidification strategy.
[0108] In this embodiment of the application, in order to ensure that the internal fruits also reach the most suitable temperature and humidity, the cooling and humidification strategy can refer to continuing home cooling and humidification. If, after a first period of time, the actual water consumption still does not reach the target water consumption and the actual cooling consumption still does not reach the target cooling consumption, then home cooling and humidification is stopped, that is, the operation of the compressor, air cooler, atomizer and atomizing fan is stopped.
[0109] Assuming the optimal storage environment for a certain fruit is temperature Toptimal and humidity Hoptimal, this means that while the actual temperature and humidity at various locations meet expectations, the amount of cooling water consumed has not reached the total amount estimated by the database. Therefore, cooling and humidification continue. If, after a certain time T1, the actual water consumption still does not reach the target water consumption, and the actual cooling consumption still does not reach the target cooling consumption, it indicates a significant difference between the actual situation and the total amount estimated by the database. To avoid a large discrepancy between the actual temperature and humidity at various locations and Toptimal and Hoptimal, cooling and humidification are stopped, and the compressor, air cooler, atomizer, and atomizing fan are shut down.
[0110] If the temperature and humidity information does not meet the preset second temperature and humidity conditions, the actual water consumption reaches the target water consumption, and the actual cooling consumption reaches the target cooling consumption, then the cooling and humidification strategy is determined to be an accelerated movement strategy.
[0111] In this embodiment of the application, in order to accelerate the movement of cold air and water mist, the acceleration strategy can refer to stopping the generation of cold air and water mist, but accelerating the movement of cold air and water mist, that is, stopping the compressor and atomizer, but keeping the air cooler and atomizing fan on; if after a second period of time, the temperature and humidity information still does not meet the preset second temperature and humidity conditions, then the compressor and atomizer are turned on, and the air cooler and atomizing fan are kept on until the temperature and humidity information meets the preset second temperature and humidity conditions.
[0112] The logic here is that the amount of cooling water consumed has reached the total estimated by the database, but the actual temperature and humidity at various locations have not reached expectations. This may be due to slow diffusion, so only the diffusion of cooling air and water mist is accelerated, hence the compressor and atomizer are stopped, but the air cooler and atomizing fan continue to run;
[0113] If, after the second period of time, the temperature and humidity information still does not meet the preset second temperature and humidity conditions, it means that the actual temperature and humidity at various locations have not reached the expected level, and it is necessary to continue cooling and humidifying, turn on the compressor and atomizer, and keep the air cooler and atomizing fan running.
[0114] If the temperature and humidity information meets the preset second temperature and humidity conditions, the actual water consumption reaches the target water consumption, and the actual cooling consumption reaches the target cooling consumption, then the cooling and humidification strategy is determined to be a stop-work strategy.
[0115] In this embodiment of the application, the shutdown strategy may refer to stopping the compressor, air cooler, atomizer and atomizing fan, querying again after a third time period to determine whether the above conditions are met, and repeating the above process.
[0116] In yet another embodiment of this application, as Figure 6 As shown, a preservation control device is also provided, comprising:
[0117] The acquisition module 11 is used to acquire object information of the object to be preserved in the first space and environmental information of the environment in which the object to be preserved is directly or indirectly located.
[0118] Extraction module 12 is used to extract the weight information of the object to be preserved from the object information;
[0119] The determining module 13 is used to determine a cooling and humidification strategy based on the weight information and the environmental information;
[0120] The cooling and humidifying module 14 is used to cool and humidify the first space according to the cooling and humidifying strategy.
[0121] In another embodiment of this application, an electronic device is also provided, including a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus.
[0122] Memory, used to store computer programs;
[0123] The processor, when executing a program stored in memory, implements the preservation control method described in any of the foregoing method embodiments.
[0124] The electronic device provided in this invention allows the processor to execute a program stored in the memory to determine a refrigeration and humidification strategy by combining the weight information of the object being preserved with environmental information about the environment in which the object is directly or indirectly located. This strategy takes into account the impact of the heat emitted by the object's respiration on the ambient temperature, avoiding a mismatch between the refrigeration and humidification control and the required refrigeration and humidification amount due to neglecting the object's respiration. This makes the refrigeration and humidification control in the preservation basket device more closely match the actual refrigeration and humidification needs of the object, thereby improving the preservation effect and reducing the spoilage rate of the object.

[0126] The communication interface 1120 is used for communication between the above-mentioned electronic device and other devices.
[0127] The memory 1130 may include random access memory (RAM) or non-volatile memory, such as at least one disk storage device. Optionally, the memory may also be at least one storage device located remotely from the aforementioned processor.
[0128] The processor 1110 mentioned above can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components.
