Description

Technical Field

[0001] The present invention relates to the technical field of fresh product distribution, and in particular to an unattended fresh product e-commerce cold chain system for merchants. Background Art

[0002] With the rapid development of fresh food e-commerce, the cold chain distribution of fresh food has become the focus of the industry. At present, the distribution of fresh food mainly adopts the full cold chain logistics model from the place of production to the terminal merchants, and the freshness of fresh food is ensured by refrigerated trucks, insulated boxes and other equipment.

[0003] In the process of fresh food distribution, the trunk transportation link from the production area to the urban distribution center has become relatively mature. The production base uses standardized pre-processing equipment to sort and package fresh products, and then transports them to the urban distribution center through cold chain logistics vehicles. The distribution center sorts and distributes goods according to order requirements, and delivers fresh products to terminal merchants through refrigerated trucks or delivery boxes.

[0004] However, in the last mile of delivery, especially for catering merchants in the city center, the existing technology still has many problems. First, there is a widespread traffic congestion problem in the city center, and some areas have restrictions on delivery vehicles, resulting in low delivery efficiency during the day. Second, it is often difficult to match the business hours of merchants with the delivery time, which may cause delays in the handover of fresh products.

[0005] To solve the above problems, some delivery services have begun to try night delivery mode. However, night delivery faces new technical challenges: on the one hand, merchants are unattended during non-business hours, making it difficult to receive goods in time; on the other hand, since merchants store various items, allowing delivery personnel to enter when no one is on duty may bring safety hazards, and it is difficult to clarify the responsibility in the event of loss of items.

[0006] At present, there is an existing technology that sets up unattended receiving devices outside the merchant's door, but due to restrictions on urban management regulations, such solutions are difficult to promote. At the same time, due to restrictions on fire and other safety regulations, large-scale engineering renovation of merchant premises is not feasible.

[0007] Therefore, there is an urgent need for an unattended fresh food delivery solution that can not only ensure delivery efficiency but also ensure the safety of merchants’ property and is easy to promote and implement. Summary of the invention

[0008] In view of this, the present invention proposes an unattended fresh food e-commerce cold chain system for merchants. By setting up a physically isolated independent receiving area in the merchant's business premises and configuring a corresponding access control system, combined with modular packaging, full-process cold chain transportation and intelligent monitoring and other technical means, the whole process of traceable distribution of fresh products from the place of origin to the merchant can be achieved, solving the problem of unattended receiving of merchants in the city center area at night.

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the present invention provides an unattended fresh food e-commerce cold chain system for merchants, comprising: The production system includes: sorting and standardizing fresh products, and packing the processed fresh products into modular packaging boxes at the production base. The modular packaging boxes are equipped with multiple sensors to monitor the temperature and humidity data in the boxes during delivery; Trunk cold chain system, equipped with trunk cold chain, used to transport modular packaging boxes from the production base to the central warehouse; The distribution center system is equipped with distribution vehicles to distribute modular packaging boxes to each distribution vehicle according to orders in the central warehouse; The unattended delivery system includes: an independent receiving area and an access control system. The independent receiving area is used to receive and store delivered modular packaging boxes, and the access control system is used to authorize delivery personnel to enter the independent receiving area. Among them, the independent receiving area is set up at the merchant's premises and is physically isolated from the merchant's main business area.

[0024] It should be noted that in the field of fresh food e-commerce delivery, especially in the delivery scenario of fresh food ingredients for catering merchants, the key link of product quality control lies in the handover link in the last mile delivery process. In the existing technology, the transportation link of fresh products from the place of origin to the urban distribution center has realized the whole cold chain, but in the last link of delivery to the merchant, due to the mismatch between the delivery time and the merchant's receiving time, the fresh products cannot enter the merchant's refrigeration facilities in time, resulting in quality loss. This problem is particularly prominent in the unattended situation. In view of the distribution characteristics of the central area of ​​the city, the traditional daytime delivery mode faces many constraints: on the one hand, urban traffic congestion seriously affects the delivery efficiency; on the other hand, some areas impose traffic restrictions on delivery vehicles. In order to improve the delivery efficiency, adjusting the delivery time to nighttime has become an inevitable choice. However, nighttime delivery faces the challenge of unattended merchants, which is mainly reflected in two aspects: first, various items are stored in the merchant's premises, and allowing delivery personnel to enter when unattended may bring safety hazards; second, once the loss of items occurs, it is difficult to define the responsibility. Existing technologies have attempted to solve this problem by installing unattended receiving devices outside the doors of businesses, but this has not been widely adopted due to urban management regulations. At the same time, large-scale engineering renovations of business premises are not feasible due to the need to comply with fire and other safety regulations.

[0025] In view of the above technical problems, the present invention proposes an unattended fresh food e-commerce cold chain system for merchants. The system sets up a physically isolated independent receiving area at the merchant's premises, and adopts existing space isolation or post-isolation devices according to the actual structural characteristics of the merchant's premises to achieve effective isolation between the distribution area and the merchant's main business area. At the same time, by configuring an intelligent access control system, refrigeration equipment and a monitoring system, the safety and traceability of the distribution process are ensured. This solution does not require large-scale renovation of the merchant's premises, is easy to promote and implement, and provides an innovative technical path to solve the problem of fresh food nighttime distribution for merchants in the city center.

[0026] Specifically, in one embodiment of the present invention, the modular packaging box is used to package fresh products from the production base. The production base refers to the upstream agricultural product supply base, which is the initial processing site for fresh products and is equipped with automatic sorting equipment for sorting and standardizing fresh products according to merchant orders. The processed fresh products are loaded into modular packaging boxes. These boxes use stainless steel boxes and food-grade plastic covers. There are small hole sealing devices on the covers, which can effectively discharge oxygen and extend the shelf life. Each modular packaging box is equipped with multiple sensors and short-range wireless communication modules. The sensors include temperature sensors, collision sensors and odor sensors, which are used to monitor the temperature, collision conditions and odor changes in the modular packaging boxes; the short-range wireless communication module is used to communicate with the central distribution refrigerator. The production base will feedback the production situation and processing progress to the central server to ensure that the information of the entire supply chain is transparent and traceable.

[0027] Specifically, in one embodiment of the present invention, the production system also includes a precooling device and an exhaust device. The precooling device includes: a precooling chamber, which is a closed space made of stainless steel, with multi-layer shelves inside, for accommodating multiple modular sub-packaging boxes to be processed at the same time; a refrigeration system, including a compressor, a condenser, a throttle valve and an evaporator, which controls the temperature of the precooling chamber within a preset range through the circulation of refrigerant; a temperature monitoring device, including a plurality of temperature sensors, which are respectively arranged at different positions in the precooling chamber, for real-time monitoring of the temperature changes of the modular sub-packaging boxes during the precooling process; a control panel, which is used to set and display precooling parameters, and automatically adjust the operating state of the refrigeration system according to the temperature monitoring results. The exhaust device includes: a vacuum exhaust device, which is composed of a vacuum pump, a gas filter and a pipeline system, and is used to extract the air in the modular sub-packaging box; an air pressure detection device, including a precision air pressure sensor, which is used to monitor the vacuum degree in the modular sub-packaging box; a control system, which uses a PLC controller to automatically adjust the exhaust process according to the detection results, so that the vacuum degree in the box is maintained within the set range; a sealing detection device, which is used to detect the sealing performance of the modular sub-packaging box to ensure the exhaust effect.

[0028] In the specific implementation process, fresh products are sorted and loaded into modular packaging boxes, and then enter the pre-cooling device for temperature pretreatment. The pre-cooling process lasts for 30-60 minutes until the temperature inside the modular packaging box stabilizes within the preset range. After the pre-cooling is completed, the modular packaging box is transferred to the gas control unit for air extraction. The air extraction process is automatically adjusted by the control system to ensure that the vacuum degree in the box meets the requirements. The parameters of the entire processing process will be recorded by the sensors on the modular packaging box and uploaded to the central server.

[0029] This embodiment uses pre-cooling treatment to keep the fresh products at the optimal storage temperature at the beginning of packing, providing a good temperature basis for subsequent transportation links; and adjusts the vacuum degree in the box through air extraction treatment to slow down the respiration of the fresh products and extend the shelf life.

[0030] The main functions of the central server include receiving user orders, distributing orders to various production bases and central warehouses, and real-time monitoring and feedback of order processing progress. The central server achieves efficient order management and information transmission through an intelligent scheduling system to ensure accurate operations in each link.

[0031] Specifically, in one embodiment of the present invention, the trunk cold chain system can be equipped with backbone cold chain vehicles to transport modular packaging boxes from the production base to the central warehouse. These cold chain vehicles are equipped with professional refrigeration equipment to ensure the stability of temperature and humidity during transportation, thereby ensuring the quality and freshness of fresh products.

[0032] The central warehouse is a key link in order processing and delivery. According to user orders, the central warehouse arranges and combines the modular packaging boxes and selects the delivery plan according to the type of delivery vehicle. When the delivery vehicle uses a cold chain logistics vehicle with refrigeration function, the distribution center system adopts a cold chain distribution plan, and the modular packaging boxes are loaded in the onboard refrigerated space of the cold chain logistics vehicle according to order requirements. When the delivery vehicle uses an ordinary vehicle, the distribution center system is also equipped with a central distribution refrigerated box for centralized loading of multiple modular packaging boxes. Among them, the central distribution refrigerated box is equipped with an environmental monitoring system and a power supply system. The environmental monitoring system includes temperature sensors, humidity sensors and anti-collision sensors for real-time collection of box operation parameters. The power supply system is used to provide power for endurance, so that the temperature of the central distribution refrigerated box is at the refrigeration temperature.

[0033] In a specific embodiment, the central distribution refrigerated box is provided with a plurality of partitions, which divide the central distribution refrigerated box into a plurality of areas, and horizontal slide rails are installed on the left and right side walls of each area, and the slide rails extend along the depth direction of the central distribution refrigerated box; sliders matching the slide rails are installed on both sides of the modular packaging box, and the sliders are protruding parts, and the shape matches the slide rails; the modular packaging box is embedded in the central distribution refrigerated box through the matching of the sliders and the slide rails.

[0034] In one example, the internal slide rail setting of the central distribution refrigerated box: horizontal slide rails are installed on the inner wall of the central distribution refrigerated box. Each layer should have a pair of slide rails, one on the left and one on the right. The slide rails should extend along the depth of the refrigerated box so that the modular packaging boxes can slide in from the front to the back. The slide rails can be made of metal strips with L-shaped or C-shaped cross-sections to ensure sufficient strength and smoothness. The slide rails should be fixed to the inner wall of the large box and can be installed using screws or rivets. Modular packaging box slider setting: sliders matching the slide rails are installed on both sides of the modular packaging box. The slider can be a simple protrusion whose shape must match the slide rail. For example, if the slide rail is L-shaped, the slider is a flat protrusion. The slider extends along the length of the modular packaging box to ensure stability. The slider can be directly formed on the modular packaging box, or fixed to the side wall of the modular packaging box by bolts or the like.

[0035] In another example, the material of the slide rail and the slider is selected to be wear-resistant and low-friction material, such as stainless steel or high-strength plastic. A stop device is set at the end of the slide rail to prevent the small box from sliding out.

[0036] Specifically, in one embodiment of the present invention, the unattended delivery system is set up at the merchant's place, and mainly includes an independent receiving area, an access control system, a refrigeration device and a monitoring device. Among them, the independent receiving area is used to receive and store the delivered modular packaging boxes; the access control system is used to authorize the delivery personnel to enter the independent receiving area; the refrigeration equipment is used to store fresh products; and the monitoring device is used to record the delivery process. The refrigeration equipment includes: a refrigerator body, which is provided with an adjustable card slot and a data card, the adjustable card slot is used to place modular packaging boxes of different sizes, and the data card is used to communicate with the central server and upload the environmental data in the refrigerator; a scanning camera set in the refrigerator body is used to scan and record when the delivery personnel put the modular packaging boxes into the refrigerator; a first data transmission module is used to upload the content recorded by the scanning camera to the central server in real time. The monitoring device includes: a monitoring camera set in the independent receiving area, which is used to monitor the external conditions of the refrigeration equipment and the operation of the delivery personnel; a second data transmission module is used to transmit the data collected by the monitoring camera to the central server in real time.

[0037] Specifically, in this embodiment, the refrigerator body adopts a standard refrigerator structure, and the internal space can be selected from 200L to 500L capacity specifications according to the needs of merchants. The cabinet body is made of high-quality stainless steel and has good thermal insulation performance. The internal design has a multi-layer adjustable shelf system to facilitate the storage of modular packaging boxes of different specifications. The refrigerator door adopts transparent tempered glass to facilitate observation of the internal storage status. The scanning camera supports automatic recognition of one-dimensional / two-dimensional codes, has night vision function, and the scanning records are uploaded to the cloud in real time.

[0038] Specifically, in this embodiment, the surveillance camera uses a wide-angle lens, has an infrared night vision function, and supports 360° rotation. The surveillance camera covers an independent receiving area. It automatically starts high-definition recording when a person enters; triggers key monitoring when the refrigerator door is opened; starts alarm recording when the temperature is abnormal; and pushes alarm information when the system is abnormal.

[0039] In this embodiment, the overall architecture of the unattended delivery system is as follows: Independent receiving area: a physically isolated space is set up in the merchant's premises, which is completely isolated from the merchant's main business area. Access control system: a corresponding lock system is configured according to the setting method of the independent receiving area. Refrigeration equipment: an intelligent refrigerator system set up in the independent receiving area. Monitoring device: a monitoring system for recording and tracking the entire delivery process. The delivery personnel enter the independent receiving area through the access control system, put the modular packaging box into the intelligent refrigerator and complete the scanning and recording. The monitoring system records the entire delivery process, and the data is uploaded to the central server in real time.

[0040] Specifically, in one embodiment of the present invention, there are two ways to set up the independent receiving area.

[0041] like Figure 2 As shown, Figure 2 This is a simplified schematic diagram of the first setting method. The first setting method is applicable to merchants with a dual-entrance structure, that is, the merchant has the "two doors" we often mention, and the 5-15 square meter transition space between the first entrance 21 and the second entrance 22 is defined as an independent receiving area 23. At this time, the independent receiving area 23 is completely isolated from the merchant's main business area 24. Correspondingly, the access control configuration is: the first entrance 21: configure the first lock system 25 to authorize the delivery personnel to enter; the second entrance 22: configure the second lock system 26 to prevent the delivery personnel from entering the merchant's main business area 24; the lock system can use smart access control or traditional key methods. A refrigerator 27 is set in the independent receiving area 23, and the refrigerator 27 is equipped with a scanning camera 28. The delivery personnel deliver fresh products to the independent receiving area 23, and the delivery process is recorded by the surveillance camera 29 and uploaded to the central server.

[0042] like Figure 3 As shown, Figure 3It is a simplified schematic diagram of the second setting mode. The second setting mode is applicable to the merchant's place with a single entrance straight-through structure. A retractable isolation device 31 is installed on the inside of the entrance to form an independent receiving area 32, which physically isolates the independent receiving area 32 from the merchant's main business area 33. In this embodiment, the retractable isolation device 31 is made of PVC material, and can be selected as a rolling door or a sliding door. It is installed on the top slide rail for easy storage and is equipped with an electric control system. Correspondingly, the access control configuration is as follows: the merchant's door 34: equipped with a lock system 35 to authorize delivery personnel to enter; the retractable isolation device 31: equipped with an independent lock system to ensure the safety of the merchant's main business area 33. Among them, the isolation device 31 can be stored during daytime business without affecting normal operations; during nighttime delivery, the isolation device is unfolded to form an independent receiving area 32. A refrigerator 36 is set in the independent receiving area 32, and a scanning camera 37 is installed in the refrigerator 36. The delivery personnel deliver fresh products to the independent receiving area 32, and the delivery process is recorded by the monitoring camera 38 and uploaded to the central server.

[0043] Two specific embodiments are used for illustration: For the merchant places with front and back double entrance structures, this implementation plan makes full use of their natural space advantages for transformation. Specifically, the transition space of about 5-15 square meters between the first entrance and the second entrance is designated as an independent receiving area. The first lock system is installed at the first entrance, and the intelligent access control or traditional key method can be selected to authorize the delivery personnel to enter; the second lock system is installed at the second entrance to ensure that the delivery personnel cannot enter the main business area of ​​the merchant. A standard refrigerator is installed in the independent receiving area, and the refrigerator is equipped with an adjustable card slot system to facilitate the storage of modular sub-packaging boxes of different specifications. At the same time, a surveillance camera is installed in the independent receiving area to cover the entire receiving area, especially the area around the refrigerator. When the delivery personnel need to deliver, they first enter the independent receiving area through the first lock system of the first entrance and push the central delivery box on the delivery vehicle to the front of the refrigerator. The delivery personnel take out the modular sub-packaging boxes in turn, scan them with the scanning camera built into the refrigerator, and put the sub-packaging boxes into the corresponding card slot position of the refrigerator after the system confirms. The whole process is recorded by the monitoring system and uploaded to the central server in real time through the data transmission module. After delivery is completed, the delivery personnel confirm that the refrigerator door is closed and locked, and then leave through the first entrance. This setting method makes full use of the merchant's original spatial structure, without the need for additional modification, and achieves complete physical isolation between the delivery area and the merchant's business area, ensuring both the convenience of delivery and the safety of the merchant's property.

[0044] For business premises with only a single entrance through-type structure, this implementation plan proposes a solution for a retractable isolation device. In specific implementation, a top slide rail is installed on the inside of the merchant's door, a PVC rolling door or sliding door is selected as the isolation device, and an electric control system is equipped to realize the opening and storage of the isolation device. The installation process of the isolation device is simple and can be completed in about 10 minutes. It is low-cost and easy to maintain. A locking system is installed at the merchant's door to authorize delivery personnel to enter; an independent locking system is installed on the isolation device to prevent delivery personnel from entering the merchant's main business area. Standard refrigerators and monitoring systems are also installed in the designated independent receiving area. During daytime business, merchants can store the isolation device on the top slide rail without affecting normal operations; during nighttime delivery, the isolation device is lowered and locked to form an independent receiving space. After the delivery personnel arrive, they enter through the lock system of the merchant's door. At this time, the isolation device is already in a locked state, and the delivery personnel can only move in the independent receiving area outside the isolation device. The delivery process is the same as the first setting. The delivery personnel push the central delivery box to the front of the freezer and take out the modular packaging boxes one by one for scanning and storage. The whole process is also recorded by the monitoring system to ensure the traceability of the delivery process. This setting can achieve physical isolation through simple transformation, which not only meets the city management regulations but also avoids complex engineering transformation, providing a cost-effective and practical unattended delivery solution for merchants in the city center.

[0045] In summary, in one example, the specific process of an unattended fresh food e-commerce cold chain system for merchants provided by the present invention is as follows: 1. Order generation stage B-side users place orders through multiple channels, such as mini programs, e-commerce websites, social platforms, and telephones. The system automatically generates an order number and associates merchant information. It also generates a modular packaging box demand list.

[0046] 2. Production and distribution preparation stage Fresh produce is sorted and standardized at the production base. It is packed into modular packaging boxes according to the specifications of about 3 kg. Each packaging box is equipped with a sensor to monitor: temperature data, humidity data, and anti-collision data. The packaging box is pre-cooled and degassed. Each packaging box is marked with a unique QR code.

[0047] 3. Trunk line transportation stage Use the trunk cold chain to transport the sub-packaging boxes to the central warehouse. The temperature is monitored throughout the process to ensure 0-4℃. Track the transportation status in real time.

[0048] 4. Urban distribution stage Determine whether to use a central distribution refrigerated box based on the type of delivery vehicle. If a central distribution refrigerated box is used, the sub-packaging boxes will be loaded into the central distribution refrigerated box according to the order requirements. Each central distribution refrigerated box can load 10-50 kilograms. The central distribution refrigerated box is equipped with an environmental monitoring system to monitor temperature, humidity, and anti-collision parameters. It is also equipped with a power supply system to ensure the normal operation of the central distribution refrigerated box.

[0049] If a cold chain logistics vehicle is used directly, the packaging boxes should be classified according to the orders and loaded into the refrigerated space on board the cold chain logistics vehicle in sections.

[0050] 5. Unattended delivery stage The delivery personnel arrive at the merchant's premises at night and enter the independent receiving area through the access control system: if it is a double-entry structure, use the key of the first door to enter the isolated area; if it is a single-entry structure, use the door lock system to enter the rear isolated space.

[0051] Push the modular packaging box to the front of the freezer, take out the modular packaging boxes one by one, and scan them with the built-in scanning camera of the freezer. After the scan is successful, put the packaging box into the corresponding card slot of the freezer, and make sure the freezer door is closed and locked. If the scan is unsuccessful, the delivery staff can manually enter the delivery according to the number of the modular packaging box and the corresponding order information on the system and notify the order user.

[0052] During the entire operation of the delivery personnel, the scanning camera records the storage process. The monitoring camera records the delivery process. The storage process and the delivery process are uploaded to the central server in real time. After confirmation, the system generates a delivery completion record.

[0053] The system provided by the present invention ensures the cold chain storage from the production base to the merchant, realizes unattended safe delivery, and ensures the traceability of the delivery process through multiple monitoring and data recording. The whole system not only guarantees the quality of fresh products, but also improves the delivery efficiency, solving the problem of nighttime delivery in the central area of ​​the city.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
