Description

Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a processing method based on a fresh-keeping storage system. Background Art

[0002] At present, the main methods for food preservation and storage are cold storage and controlled atmosphere preservation. However, both preservation methods require a relatively stable storage environment to ensure the preservation effect of food. For the preservation needs of special scenarios, it is often difficult to achieve the ideal food preservation effect due to certain limitations. For example, for the preservation of food on ships, modern ships have longer and longer sailing times. In order to ensure the quality of life of the crew, they usually need to load a large amount of fruits, vegetables, grains, meat and other foods. The fruits and vegetables loaded on ships have the characteristics of many varieties and a small amount of single varieties. Due to the daily consumption needs of fruits and vegetables, the doors of the warehouses where fruits and vegetables are stored will be opened and closed frequently, and frequent opening and closing of the doors will cause large fluctuations in the environment in the warehouse. For warehouses using the cold storage preservation method, frequent opening and closing of the doors will cause the hot air outside the warehouse to exchange with the cold air inside the warehouse, seriously affecting the ambient temperature inside the warehouse, and the fluctuation of ambient temperature will seriously affect the quality of the stored food; for warehouses using the controlled atmosphere preservation method, frequent opening and closing of the doors will destroy the atmosphere in the warehouse, which will also reduce the preservation effect of food. In addition, in terms of inventory management, the types and loading quantities of food stored in traditional warehouses are usually recorded manually. Due to the cumbersome statistical and query processes, recording errors are very easy to occur. In addition, the preservation parameters of each food are different and need to be set manually. The wide variety of loaded foods requires a high level of professionalism from the operators. More importantly, the low-temperature and low-oxygen warehouses can cause harm to the people who enter the warehouse to work. Summary of the invention

[0003] In view of the technical problems existing in the prior art, the present invention proposes a processing method based on a fresh-keeping storage system to reduce environmental fluctuations in the warehouse and improve the fresh-keeping effect of fruits and vegetables.

[0004] In order to solve the above technical problems, the present invention provides a processing method based on a fresh-keeping storage system, wherein the fresh-keeping storage system includes a warehouse, fresh-keeping equipment, a handling device and a management and control device, an article access window is provided on the enclosure structure constituting the warehouse, and the warehouse is equipped with a shelf, and the shelf is used to place turnover baskets for storing fruits and vegetables, wherein the method includes the following steps: the management and control device determines the environmental parameters of the storage space inside the warehouse according to the fruits and vegetables stored in the warehouse, and sends them to the fresh-keeping equipment; the fresh-keeping equipment works according to the determined environmental parameters to provide a fresh-keeping environment for the storage space inside the warehouse; the management and control device generates a handling instruction to the handling device according to the needs of fruits and vegetables entering / exiting the warehouse; and the handling device transports the turnover basket between the shelf and the article access window according to the received handling instruction.

[0005] The present invention is provided with a transport device in the warehouse, and an article access window is opened on the enclosure structure of the warehouse. When taking out articles such as fruits and vegetables from the warehouse during the preservation process, the transport device is controlled by the management control device, and the transport device replaces the staff to take out the fruits and vegetables from the shelves in the warehouse, and passes them to the staff through the article access window. Therefore, the staff does not need to open the warehouse door to enter the warehouse, thus avoiding frequent opening and closing of the warehouse door. The area of ​​the article access window is much smaller than that of the warehouse door. Therefore, the fruit and vegetable access method of the present invention reduces the influence of the preservation environment in the warehouse, thereby improving the preservation effect of fruits and vegetables; at the same time, it also avoids the damage of the warehouse environment to the body of the staff.

[0017] In the following detailed description, reference may be made to the various specification drawings that are part of the present application and are used to illustrate specific embodiments of the present application. In the accompanying drawings, similar reference numerals describe substantially similar components in different figures. The various specific embodiments of the present application are described below in sufficient detail so that a person of ordinary skill in the art with relevant knowledge and skills in the art can implement the technical solutions of the present application. It should be understood that other embodiments may also be used or structural, logical or electrical changes may be made to the embodiments of the present application.

[0018] The present invention provides a processing method based on a fresh-keeping storage system, wherein the fresh-keeping storage system includes a warehouse, a fresh-keeping device, a handling device, and a management and control device. The warehouse includes a storage space formed by an enclosure structure, and the enclosure structure is provided with an article access window; the storage space is built with a shelf, and the shelf is used to place a turnover basket for storing fruits and vegetables; the fresh-keeping device is installed inside and / or outside the warehouse, and the handling device is placed in the storage space, and the management and control device is connected to the fresh-keeping device and the handling device.

[0019] Figure 1A It is a flow chart of a processing method based on a fresh-keeping storage system according to an embodiment of the present invention.

[0020] In this embodiment, the processing method includes the following steps:

[0021] Step S1, the management and control device determines the environmental parameters of the storage space inside the warehouse according to the fruits and vegetables stored in the warehouse, and sends them to the preservation equipment.

[0022] Step S2, the fresh-keeping equipment operates according to the determined environmental parameters to provide a fresh-keeping environment for the storage space inside the warehouse. In this embodiment, the fresh-keeping environment is a low-temperature and low-oxygen fresh-keeping environment.

[0023] Step S3, the management control device generates a transport instruction to the transport device according to the storage requirements of fruits and vegetables.

[0024] Step S4: the transport device transports the turnover basket between the shelf and the article access window according to the received transport instruction.

[0025] Figure 1BIt is a structural schematic diagram of a warehouse according to an embodiment of the present invention. In this embodiment, the warehouse 1 is composed of a storage space formed by an enclosure structure 10, and the enclosure structure 10 is, for example, an insulation board. An airtightly connected item access window 101 is provided on the enclosure structure, and a storage table 102 is provided corresponding to the item access window 101 for placing items such as turnover boxes. The storage space is built with a shelf 11, and the shelf is used to place a turnover basket 12 for storing fruits and vegetables. The turnover basket 12 is provided with an electronic tag for recording information about fruits and vegetables stored in the turnover basket 12. The shelf 11 includes a plurality of coded storage locations, and the turnover basket 12 is placed on the storage location of the shelf 11. Correspondingly, the management and control device obtains the electronic tag information when fruits and vegetables are put into storage, and establishes an association relationship between the turnover basket 12 and the storage location of the shelf 11.

[0026] Structurally, the warehouse 1 of the present invention includes, in addition to the conventional warehouse door 103, an article access window 101 for accessing the turnover basket 12. When the fruits and vegetables are first put into the warehouse, the staff will place the turnover basket 12 stacked with fruits and vegetables on the shelf storage position through the warehouse door 103, and then establish a fresh-keeping environment for the warehouse. After the fresh-keeping environment is established, the entry and exit of fruits and vegetables are realized through the article access window 101, and there is no need to open the warehouse door 103. The area of ​​the article access window 101 is set according to the size of the turnover basket 12, and the switch control of the article access window 101 is electric control, and the opening and closing speed is fast. Since the present invention changes the traditional way of taking through the warehouse door with a larger area to the way of taking through the article access window 101 with a smaller area, the fluctuation caused by the frequent opening and closing of the door to the warehouse fresh-keeping environment is reduced, while ensuring the fresh-keeping effect of fruits and vegetables, it also reduces the number of startups of the fresh-keeping equipment, thereby reducing energy consumption. In addition, a weight sensor 44 can also be installed on the storage table 102 at the article access window 101. Used to weigh the storage and retrieval turnover basket 12 and the weight of the fruits and vegetables inside it.

[0027] The turnover basket 12 of the present invention is provided with an electronic tag. The electronic tag mainly records two aspects of information: information about the turnover basket 12 itself and information about the fruits and vegetables stored therein, the fruit and vegetable information including information such as the type of fruits and vegetables, loading weight / quantity, etc.; information about the turnover basket 12 itself including information such as the turnover basket 12 code and the storage location code of the shelf where the turnover basket is located.

[0028] The shelf 11 includes a plurality of storage locations, the size of which is adapted to the size of the turnover basket 12, and each storage location is provided with a unique code. When fruits and vegetables are put into storage, the management control device 4 obtains the fruit and vegetable information recorded in the electronic tag of the turnover basket 12 by scanning the electronic tag on the turnover basket 12, allocates a shelf storage location for the fruit and vegetable according to the fruit and vegetable information, and displays the storage location code to the operator. After the operator determines the storage location, the storage location code is written into the electronic tag of the turnover basket 12, thereby establishing an association relationship between the turnover basket 12 and the shelf storage location.

[0029] Figure 2 1 is a principle block diagram of a fresh-keeping device according to an embodiment of the present invention. The fresh-keeping device 2 comprises a temperature control system 21 and an atmosphere control system 22 .

[0030] In one embodiment, the temperature control system 21 includes a temperature control controller 210, an air conditioner 211 and an electric heating device 212. The air outlet of the air conditioner 211 is connected to the warehouse 1 to maintain the ambient temperature of the warehouse 1 within a set temperature range. The electric heating device 212 is connected between the air outlet of the air conditioner 211 and the warehouse 1 to fine-tune the temperature of the gas entering the warehouse 1. Correspondingly, a temperature sensor 213 is also provided in the warehouse 1, which is connected to the temperature control controller 210 and sends the detected current temperature information in the warehouse to the temperature control controller 210. The temperature control controller 210 controls the air conditioner 211 and / or the electric heating device 212 to work according to the current temperature in the warehouse 1 and the set temperature.

[0031] In one embodiment, the gas conditioning system 22 includes a gas conditioning controller 220 and a nitrogen generator 221. The outlet of the nitrogen generator 221 is connected to the warehouse 1 to adjust the gas conditioning environment of the warehouse 1 so that it is within the set gas conditioning range. The nitrogen generator 221 provides the required nitrogen. Correspondingly, a gas sensor 222 is also provided in the warehouse 1. The gas sensor 222 includes, for example, an oxygen sensor and a carbon dioxide sensor, which are respectively connected to the gas conditioning controller 220 to send the current oxygen concentration information and carbon dioxide concentration information detected in the warehouse 1 to the gas conditioning controller 220. The gas conditioning controller 220 controls the nitrogen generator 221 according to the current oxygen concentration, carbon dioxide concentration in the warehouse 1 and the set oxygen concentration and carbon dioxide concentration, so that it adjusts the corresponding component concentration of the gas delivered to the warehouse 1. The temperature sensor 213 and the gas sensor 222 in the aforementioned embodiment serve as environmental parameter sensors and can sense environmental changes in the warehouse 1 in real time. The preservation controllers in the preservation equipment 2, such as the temperature control controller 210 and the gas control controller 220, can make timely adjustments according to environmental changes, thereby maintaining a stable preservation environment inside the warehouse 1.

[0032] Figure 3A3 is a block diagram of the principle of a handling device according to an embodiment of the present invention. The handling device 3 in this embodiment includes a walking mechanism 31, a handling mechanism 32, a code scanning mechanism 33, a communication module 34 and a control mechanism 35. The communication module 34 of the handling device 3 receives a handling instruction from a management control device and sends it to the control mechanism 35. The control mechanism 35 is connected to the communication module 34, the walking mechanism 31, the handling mechanism 32 and the code scanning mechanism 33. After receiving the handling instruction, the control mechanism 35 generates guidance information to the walking mechanism 31 according to the specific content of the handling instruction, and the walking mechanism moves to a designated position, such as an article access window 101 or a designated shelf storage location, according to the guidance information, and feeds back to the control mechanism 35. After the control mechanism 35 determines that the current position is correct, it sends an instruction to the code scanning mechanism 33, and the code scanning mechanism 33 reads the shelf code and / or the electronic tag of the turnover basket 12, and feeds back the read electronic tag information to the control mechanism 35. After the control mechanism 35 confirms that the content of the electronic tag is correct, it sends a carrying instruction to the handling mechanism 32, and the handling mechanism 32 carries the turnover basket 12. The transport mechanism 32 includes a mechanical arm and a lifting device, and the lifting device is used to raise or lower the mechanical arm to a suitable height so that the mechanical arm can lift or put down the turnover basket 12. After the transport mechanism 32 lifts the turnover basket 12, it feeds back the information that the transport has been carried to the control mechanism 35. After confirming that the turnover basket 12 has been lifted, the control mechanism 35 generates corresponding guidance information to the walking mechanism 31 according to the destination. The walking mechanism 31 moves the turnover basket 12 to the designated destination, such as a shelf storage position or an item access window 101, according to the guidance information, and feeds back to the control mechanism 35 after reaching the designated position. After confirming that the destination position has been reached, the control mechanism 35 sends a command to rotate the turnover basket 12 to the transport mechanism 32. After receiving the command, the transport mechanism 32 puts down the turnover basket 12, thereby completing a transport task.

[0033] The handling device 3 can be implemented as an intelligent forklift, such as Figure 3B Compared with manual carts, the operation channel required for the movement of intelligent forklifts occupies a smaller area, and it has the advantage of completing the picking and placing operations in a small space. Therefore, the reserved channel between the shelves in the present invention occupies a smaller area than the channel between the shelves in the traditional warehouse, thereby improving the utilization rate of the warehouse volume.

[0034] Figure 4 4 is a principle block diagram of a management control device according to an embodiment of the present invention. In this embodiment, the management control device 4 includes a human-machine interaction interface 41 , a code scanning mechanism 42 and a controller 43 .

[0035] The human-computer interaction interface 41 is used to input various parameters and information, such as fresh-keeping environment parameters, fruit and vegetable information, etc., and display various information as needed, such as a list of fruit and vegetable varieties. In one embodiment, the human-computer interaction interface 41 can be a touch screen, a button, a display and / or an indicator light. The code scanning mechanism 42 is used as an input device to obtain the electronic tag information on the turnover basket. For example, when the operator is taking fruits and vegetables out of the warehouse or into the warehouse, the operator uses the code scanning mechanism 42 to scan the electronic tag on the turnover basket 12, so as to obtain relevant information such as the type, weight and fresh-keeping time of the fruits and vegetables placed in the electronic tag of the turnover basket. The controller 43 is connected to the human-computer interaction interface 41 and the code scanning mechanism 42, receives the information input by the human-computer interaction interface 41, outputs the information to be displayed as required; and receives the electronic tag information of the turnover basket obtained by the code scanning mechanism 42.

[0036] The controller 43 includes an environment management module 431, an outbound / inbound control module 432, an inventory management module 433, and a first communication module 434. The environment management module 431 generates the fresh-keeping environment setting parameters of the fruits and vegetables according to the information input by the operator in the human-computer interaction interface 41 and the information of the fruits and vegetables in the warehouse, and sends them to the fresh-keeping device 2; or the operator can directly input the fresh-keeping environment setting parameters through the human-computer interaction interface 41, and the environment management module 431 reads the fresh-keeping environment setting parameters and sends them to the fresh-keeping device 2. The outbound / inbound control module 432 locates the fruits and vegetables to be outbound according to the outbound instruction information from the human-computer interaction interface 41 and generates a handling instruction; and locates the storage location of the inbound fruits and vegetables according to the inbound instruction information from the human-computer interaction interface 41 and generates a handling instruction. The inventory management module 433 is used to update the inventory information according to the outbound / inbound fruits and vegetables information, for example, to establish an inventory list according to the newly inbound fruits and vegetables, and to update the inventory list at each outbound / inbound. In addition, the inventory management module 433 also stores a shelf storage location list for recording storage location codes.

[0037] In one embodiment, the fresh-keeping storage system of the present invention is used on a ship to store fruits and vegetables. The process of loading fruits and vegetables into the warehouse for the first time is as follows:

[0038] First, the operator classifies the fruits and vegetables and puts the classified fruits and vegetables into the turnover basket 12 with the electronic tag. Then, the operator clicks the storage instruction on the human-machine interface 41 installed at the door of the warehouse, and uses the scanning mechanism 42 to scan the electronic tag on the turnover basket 12.

[0039] The human-machine interface 41 sends the storage instruction to the controller 43, and the scanning mechanism 42 sends the electronic tag information of the turnover basket 12 to the controller 43. When the controller 43 receives the storage instruction and the electronic tag information of the turnover basket 12, the inventory management module 433 in the controller 43 sends the label information filling information and the fruit and vegetable list to the human-machine interface 41 for display. The human-machine interface 41 here can be a display device such as a touch screen or a display.

[0040] When the label information filling screen and the fruit and vegetable list are displayed on the touch screen, the operator selects the fruit and vegetable varieties and loading quantities to be stored in the screen, and clicks the confirmation button or key after filling in. The human-computer interaction interface 41 sends the storage information to the inventory management module 433.

[0041] After receiving the warehousing information, the inventory management module 433 queries the shelf storage location list according to the fruit and vegetable varieties in the warehousing information. In one embodiment, the interior of the warehouse is divided into different storage areas. For example, the entire storage space is divided into a vegetable area and a fruit area, and the vegetable area and the fruit area are respectively divided into different areas, which correspond to specific shelf storage locations. The available shelf storage locations can be determined by querying the shelf storage location list according to the fruit and vegetable varieties in the warehousing information, and a storage location for the current warehousing turnover basket is specified from the available shelf storage locations, and the storage location coding information is transmitted to the human-computer interaction interface 41 for display. The operator puts the turnover basket into the corresponding shelf storage location in the warehouse according to the storage location code displayed on the touch screen, and confirms that the warehousing is completed. The human-computer interaction interface 41 sends the confirmation information to the inventory management module 43, and the inventory management module 43 writes the shelf storage location code into the electronic tag of the turnover box, thereby establishing an association relationship between the turnover basket and the shelf storage location. At this point, a warehousing operation is completed.

[0042] For the storage of the remaining fruits and vegetables, the operator only needs to follow the above steps in sequence until the storage is completed. In one embodiment, after all fruits and vegetables are stored, the operator clicks the button for the completion of the initial storage on the human-computer interaction interface 41. After receiving the storage completion information, the inventory management module 433 counts the types of fruits and vegetables stored, the loading volume, the turnover basket, the cargo location code and other information, and displays the statistical information on the human-computer interaction interface 41, prompting the operator to review and confirm the inventory. After the operator confirms, the inventory management module 433 sends the inventory statistical information to the environmental management module 431. The environmental management module 431 internally stores various preservation parameters, such as the temperature range, oxygen concentration and carbon dioxide concentration corresponding to different fruit and vegetable varieties. When the environmental management module 431 receives the current inventory statistical information, it queries the preservation parameters according to the fruit and vegetable varieties in the inventory statistical information, thereby determining the appropriate preservation parameters, and sends them to the preservation device 2 through the first communication module 434.

[0043] When all fruits and vegetables are put into storage, the operator closes the door of the warehouse and clicks the fresh-keeping button on the human-machine interaction interface 41 at the door of the warehouse. The fresh-keeping device 2 starts working and establishes a fresh-keeping environment for the warehouse according to the fresh-keeping parameters.

[0044] Fruit and vegetable storage on ships is different from conventional fruit and vegetable storage. Conventional fruit and vegetable storage involves frequent replenishment, such as in ordinary supermarket fruit and vegetable warehouses, while ships usually load all the required fruits and vegetables into the warehouse at one time before sailing. Therefore, in order to extend the fresh-keeping time of fruits and vegetables during the voyage, the present invention adopts a low-temperature, low-oxygen fresh-keeping process, that is, maintaining a low-temperature, low-oxygen fresh-keeping environment in the warehouse.

[0045] Generally speaking, the oxygen content in the air is between 21% and 22%. This range varies according to the region and altitude. The lower the altitude, the higher the oxygen content. Conversely, the higher the altitude, the lower the oxygen content. The oxygen content of air at normal temperature and pressure is about 21%, and the oxygen content of 19.5% is the critical value that the human body can withstand. If the oxygen content of the air is lower than 19.5%, people's breathing will accelerate, and people will feel tired and powerless. When the oxygen content of the air is lower than 12%, people's breathing will become difficult. When the oxygen content is lower than 10%, people will vomit, be unable to move, lose consciousness or even die. The low-temperature, low-oxygen preservation process adopted by the present invention requires that the oxygen content of the air in the preservation environment is 3-5%. If the traditional operation of the operator entering the warehouse to carry out the entry / exit operation of fruits and vegetables is adopted, it is necessary to carry an additional oxygen inhalation device, otherwise it will cause great harm to the operator's body. However, the operation requirement of carrying an additional oxygen inhalation device every time will not only cause trouble to the operator, but also cause harm to the operator if there is a problem with the oxygen inhalation device during the operation. Therefore, in the present invention, when the warehouse environment before departure is in a state of normal temperature and normal oxygen, the operator completes the initial storage operation of fruits and vegetables, and after the fresh-keeping environment is established, the handling device in the warehouse completes the storage / in and out operation of fruits and vegetables, which not only ensures the safety of the operator, but also reduces the workload of the operator, and at the same time will not damage the fresh-keeping environment in the warehouse.

[0046] After the fresh-keeping environment in the warehouse is established, when it is necessary to take fruits and vegetables from the warehouse, the management control device 4 can control the handling device 3 to complete the outbound operation of fruits and vegetables. Specifically, the operator clicks the outbound button on the human-computer interaction interface 41. In one embodiment, when the outbound / inbound control module 432 receives the outbound instruction, it displays the internally stored inventory list on the human-computer interaction interface 41. For example, the turnover basket and its built-in fruit and vegetable information are displayed, and the operator can select a specific turnover basket, and can select one or more at a time. The outbound / inbound control module 432 reads the electronic tag information of the turnover basket selected by the operator to obtain the turnover basket code and the corresponding shelf storage location code, and generates a handling instruction, which is sent to the handling device 3 through the first communication module 434, wherein the handling instruction includes the turnover basket code and the shelf storage location code. In another embodiment, an input box is displayed on the human-computer interaction interface 41, and the operator enters the name and quantity / weight of the fruit and vegetable. At this time, the outbound / inbound control module 432 queries the inventory list according to the name and quantity / weight of the fruit and vegetable input by the operator, determines the matching turnover baskets and quantity, and if the current inventory has a corresponding number of turnover baskets, locates the corresponding turnover basket according to the fruit and vegetable information, reads its electronic tag information to obtain the turnover basket code and shelf storage location code, and generates a handling instruction, which is sent to the handling device 3 through the first communication module 434, wherein the turnover basket code and shelf storage location code are included in the handling instruction. If there are not enough fruits and vegetables in the inventory or there are no fruits and vegetables that the operator wants to take, a prompt message is sent and displayed on the human-computer interaction interface 41. If there are multiple turnover baskets, in one embodiment, the outbound / inbound control module 432 generates a handling order according to the positions of the multiple turnover baskets, and includes the handling order in the handling instruction. In another embodiment, the handling order can be determined by the handling device 3.

[0047] After the handling device 3 receives the handling instruction from the management control device 4 through its own communication module 34, its control mechanism 35 generates guidance information according to the shelf storage location code in the handling instruction and the shelf storage location distribution map stored internally, and sends the guidance information to the walking mechanism 31. The walking mechanism 31 moves to the corresponding shelf storage location according to the guidance information. After the control mechanism 35 confirms that the handling device 3 has reached the predetermined shelf storage location, it sends a code scanning instruction to the code scanning mechanism 33, and the code scanning mechanism 33 scans the electronic tag of the turnover basket and sends it to the control mechanism 35. The control mechanism 35 compares whether the electronic tag information of the turnover basket is consistent with the information in the handling instruction. If it is consistent, it controls its handling mechanism 32 to take out the turnover basket, and then controls the walking mechanism 31 to transport the turnover basket to the item access window 101 of the warehouse according to the path in the guidance information. In one embodiment, a sensor is provided at the article access window 101. When a turnover basket is sensed, the electric control mechanism of the article access window 101 is activated, the article access window 101 is opened, the storage table 102 is put down, and the handling device 3 places the turnover basket on the storage table 102. When the operator takes away the turnover basket on the storage table 102, the electric control mechanism of the article access window 101 is activated, the storage table 102 is folded, and the article access window 101 is closed. At the same time, information is sent to the controller 43 to determine that the outbound operation is completed. When the outbound / inbound control module 432 receives that the outbound operation is completed, it sends the outbound turnover basket information to the inventory management module 433. The inventory management module 433 updates the inventory information. When there are multiple turnover baskets that need to be outbound, the handling device 3 repeats the above operations in sequence to complete the outbound operation of the remaining turnover baskets in turn.

[0048] When the transport device 3 completes all transport instructions, it will execute a standby command to return to the designated position in the warehouse. In one embodiment, when the management control device 4 does not send a transport instruction to the transport device 3, the transport device 3 waits at the article access window 101.

[0049] Figure 5 FIG. 4 is a block diagram of a controller according to another embodiment of the present invention. In this embodiment, the controller 4 in the management and control device includes Figure 4 In addition to the environment management module 431 , the in / out control module 432 , the inventory management module 433 and the first communication module 434 described in the embodiment, the system further includes a second communication module 435 for communicating with the host computer 5 .

[0050] The second communication module 435 can be a wireless module such as WiFi, which communicates with the host computer, so that it can receive instructions and related information from the host computer, and send the related information generated by the environment management module 431, the storage control module 432 and the inventory management module 433 to the host computer through the second communication module 435. The host computer 5 can be a mobile terminal or a monitoring platform. For example, the operator can query the inventory status, current environmental parameters and other information through the host computer, and can also modify the environmental preservation parameters, and remotely send outbound instructions and outbound information. The controller can send the warehouse storage data, the working status of the equipment of the entire system, such as the working status of the preservation equipment, the handling device, the electric control mechanism of the item access window 101, etc. to the host computer, so that the management personnel can remotely monitor the entire working status of the storage system provided by the present invention.

[0051] Figure 6 FIG. 4 is a block diagram of a management control device according to another embodiment of the present invention. In this embodiment, the management control device 4 includes Figure 4In addition to the human-computer interaction interface 41, the code scanning mechanism 42 and the controller 43, a weight sensor 44 is also included, which can be installed at the item access window 101, such as on the storage table 102, or set on a separate weighing table (not shown in the figure), and connected to the management and control device 4. In one embodiment, when the fruits and vegetables are first put into storage, the weight sensor 44 can accurately weigh the weight of the fruits and vegetables in the storage and access turnover basket, and the inventory management module 433 records the weight information into the electronic tag of the turnover basket. In another embodiment, when the fruits and vegetables are out of the warehouse, when the operator does not take away all the fruits and vegetables in the turnover box, the operator needs to perform another storage operation at this time to store the turnover box and the remaining fruits and vegetables inside it in the warehouse. At this time, the operator clicks the storage button or key on the human-computer interaction interface 41, and uses the code scanning mechanism 42 to scan the electronic tag of the turnover basket. After the electronic tag information is displayed on the machine interaction interface 41, the operator revises the electronic tag information, and at the same time, the weight sensor of the storage table sends the weight of the turnover basket to the management and control device 4. The inventory management module 433 in the management and control device 4 receives the electronic tag information of the turnover basket modified by the operator, writes the weight information into the electronic tag, and updates the corresponding information in the inventory. The management and control device 4 queries the shelf storage distribution map according to the types of fruits and vegetables in the turnover basket, and allocates storage locations for the turnover basket. After receiving the storage instruction, the out / in storage control module 432 generates a handling instruction, which includes the turnover basket code and the shelf storage location code information in the handling instruction, and sends it to the handling device 3 through the first communication module 434. The handling device 3 generates guidance information according to the destination shelf storage location and the current position, and transports the turnover basket at the item access window 101 to the destination shelf storage location according to the guidance information. If there are multiple turnover baskets that need to be stored, the multiple turnover baskets are stored in the corresponding shelf storage locations in the warehouse according to the above process.

[0052] Figure 74 is a principle block diagram of a fresh-keeping storage system according to another embodiment of the present invention. In this embodiment, the management and control device also includes a fresh-keeping control module 435 for controlling the operation of the fresh-keeping device 2. In this embodiment, after the environmental management module 431 obtains the set fresh-keeping parameters according to the built-in fruits and vegetables, it sends them to the fresh-keeping control module 435, and the fresh-keeping control module 435 controls the operation of the fresh-keeping device according to the set fresh-keeping parameters. Correspondingly, an environmental parameter sensor 23 is installed in the warehouse, such as a temperature sensor and a gas sensor 222 such as an oxygen sensor and a carbon dioxide sensor. The environmental parameter sensor 23 senses the environmental parameters in the warehouse in real time and sends them to the fresh-keeping control module 435. For example, the fresh-keeping control module 435 controls the cooling of the air-conditioning device in the fresh-keeping device according to the set temperature, and at the same time compares the real-time temperature in the warehouse sensed by the temperature sensor in the warehouse with the set temperature, and adjusts the refrigerant flow of the air-conditioning device according to the comparison result, so that the warehouse temperature finally reaches the set temperature and is maintained within the allowable temperature variation range. Similarly, the fresh-keeping control module 435 controls the nitrogen-making device 221 in the fresh-keeping equipment 2 to distribute gas according to the set gas-conditioning parameters according to the set gas-conditioning parameters. When the requirements are met, the gas replacement is performed for the warehouse. During the gas replacement process, the real-time gas concentration sensed by the gas sensor 222 in the warehouse is adjusted to adjust the gas replacement process until the gas in the warehouse meets the gas-conditioning parameters. Usually, the fresh-keeping control module 435 first replaces the gas in the warehouse, and then cools it down, and finally obtains a fresh-keeping environment that meets the requirements. In the process of fruit and vegetable preservation, the fresh-keeping control module 435 monitors in real time whether the environment in the warehouse has changed through the environmental parameter sensor 23, and promptly controls the relevant fresh-keeping equipment to maintain the fresh-keeping environment in the warehouse. The fresh-keeping control module 435 can also receive information or instructions input by the operator through the human-computer interaction interface 431 to control the corresponding fresh-keeping equipment, and can also send the real-time environmental parameters in the current warehouse to the human-computer interaction interface 431 for display. Regarding the communication with the fresh-keeping device, it can be implemented as wired communication, that is, when the installation position of the controller 43 is close to the fresh-keeping device 2, the controller 43 and the fresh-keeping device 2 can be connected by wire. Or a wireless method can be used, for example, the controller 43 is provided with a wireless transmission module, and the fresh-keeping device 2 is also provided with a wireless transmission module, and instructions and information are transmitted wirelessly. Similarly, the environmental parameter sensor 23 can also transmit sensor data by wire or wirelessly.

[0053] The present invention uses a handling device arranged in the warehouse to replace the operator to implement the entry and exit of fruits and vegetables during the fruit and vegetable preservation process, thereby avoiding the disturbance of the warehouse preservation environment caused by frequent opening and closing of the warehouse door, and improving the preservation effect; since the operator does not need to enter the warehouse, a low-temperature and low-oxygen preservation environment can be adopted, further improving the preservation effect of fruits and vegetables. At the same time, the present invention can automatically set the preservation environment parameters according to the types and loading amounts of fruits and vegetables entering the warehouse, reducing the dependence on professionals; the handling device used in the present invention occupies a small area, thereby reducing the channel width between the shelves, thereby increasing the storage capacity of the warehouse. The present invention can realize automatic statistics of the types and loading amounts of stored fruits and vegetables from the initial entry of fruits and vegetables to the entry and exit of fruits and vegetables during the preservation process, reducing the probability of errors.

[0054] The above embodiments are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention.
