[0047] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in combination with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0048] Example 1

[0049] In order to solve the problem of agricultural product traceability, there may be problems in the process from production, processing, classification, transportation to storage, which may lead to unqualified agricultural products. Figure 1 As shown, this embodiment proposes a method for tracing the source of agricultural products in combination with the Internet of Things, including establishing an electronic file during the packaging process of agricultural products after the agricultural products are picked, making graphic labels according to the electronic files, obtaining the original packaging image of the agricultural products, pasting the graphic labels on the packaging of the processed products, and entering the original packaging image into the corresponding electronic file; in the process of transporting agricultural products, recording the transportation path information and the transportation time information matching the corresponding transportation path throughout the whole process, and entering the transportation path information and the transportation time information into the corresponding electronic file; in the process of warehousing agricultural products, detecting the packaging integrity, if the packaging integrity is lower than the threshold, defining the agricultural products as products to be inspected, and flowing the products to be inspected into a special processing line, tracing the electronic files of the products to be inspected according to the graphic labels, and obtaining the packaging process information and transportation process information of the products to be inspected.

[0050] First of all, in the process of planting agricultural products, complete records of the entire process from seed sowing to harvesting should be kept, including the type of seeds used, regional information on sowing, planting methods (soil or hydroponics, organic or inorganic), type of fertilizer, whether pesticides are used, etc. Since the different planting methods of agricultural products have a great impact on the quality and selling price of agricultural products, it is very necessary to ensure the seed quality and planting methods of agricultural products during the traceability process.

[0051] After the agricultural products are picked, they are packaged. During the packaging process, they are classified and packaged according to the categories of agricultural products. For example, green leafy vegetables can be packaged in baskets, and dried fruits can be packaged in plastic bags or paper tapes. After the agricultural products are packaged, electronic archives for the types of agricultural products are made. The electronic archives are recorded in the cloud. First, the terminal device communicates with the cloud server, and the electronic archives of this batch of agricultural products are established on the cloud server through the terminal device. The corresponding types of agricultural products are selected according to the types of agricultural products provided by the cloud server. Then, through the categories displayed on the terminal, the planting information of the agricultural products is filled in one by one, and the packaged agricultural products are randomly scanned. The image and the information of this batch of agricultural products are entered into the dialog box in the terminal. After the entry is completed, the information of this batch of agricultural products is stored in the cloud server to complete the establishment of the electronic archive. After receiving the corresponding request, the cloud server records the electronic archive and the time when the electronic archive is established. According to the information of the electronic archive, the cloud server produces a graphic label, which can be a QR code or a barcode. This graphic label is a lifelong graphic label for this batch of agricultural products of this category.

[0052] Preferably, during the transportation of agricultural products, the point at which the next-level transportation process receives the agricultural products of the previous-level transportation process is defined as the data collection time point; the image information of the agricultural products is scanned at the data collection time point, and the scanning time point is synchronously recorded when scanning the image information of the agricultural products, and the difference between the scanning time and the time point at which the previous-level transportation receives the agricultural products is defined as the transportation time information of the previous-level transportation process; the image information of the scanned agricultural products is entered into an electronic file, and the transportation time information is waited for to be entered into the next-level transportation, and the scanned image information and transportation time information of the agricultural products at the same level are matched and sealed in the electronic file.

[0053] After the agricultural products are packaged and labeled, they are sent to the destination by means of logistics transportation. Logistics transportation can have multiple layers of shelves, and each shelf of logistics transportation needs to scan the graphic labels of agricultural products when receiving agricultural products. The information obtained after the scanning process is synchronously entered into the cloud server. The cloud server can synchronously record the IP of the scanning device. The cloud server automatically identifies the logistics supplier corresponding to the IP of the scanning device and the time of receiving the batch of agricultural products based on the IP of the scanning device. Therefore, detailed information on the first logistics reception time and the logistics service provider can be obtained.

[0054] In this way, the time when the second logistics supplier receives this batch of agricultural products is also recorded synchronously to the cloud server after the supplier scans the graphic tag. By comparing the time when the first logistics supplier receives this batch of agricultural products and the time when the second logistics supplier receives this batch of agricultural products, the time when the first logistics supplier transported this batch of agricultural products can be obtained. After recording the IP addresses of the first logistics supplier and the second logistics supplier in the cloud, the transportation route information of the first logistics supplier transporting this batch of agricultural products can be synchronously identified.

[0055] Therefore, after agricultural products have been transported by logistics suppliers for multiple times, when they are put into storage, if you need to check the logistics information of the agricultural products, you can scan the graphic labels through the terminal device to retrieve the full logistics information and full planting information of this batch of agricultural products in the electronic file, including time and route. You can also retrieve the packaging photos of the agricultural products when they are received at each intermediate process in the process.

[0056] In the final storage of agricultural products, the packaging of agricultural products is first scanned by electronic equipment to detect the integrity of the packaging. If the packaging integrity is lower than the threshold, the agricultural product is defined as a product to be inspected, and the product to be inspected flows into a special processing line. The special processing line can use manual or automatic selection, preferably automatic selection, which can save labor costs. The agricultural products entering the special processing line are traced back to the electronic files of the products to be inspected according to the graphic labels, and the packaging process information and transportation process information of the products to be inspected are obtained. By tracing the electronic files of the products to be inspected, the person responsible for the damage to the packaging of agricultural products during the production or logistics process of agricultural products can be attributed.

[0057] This system can not only check the production information and logistics information of agricultural products through the dedicated IP device, but also send the information page to the terminal through the cloud server after scanning the device by other terminals other than the dedicated IP, and only display any information of the agricultural product, but the terminal other than the dedicated IP can only view the information but cannot change it. Therefore, the information of agricultural products can also be provided to the final consumers for reference.

[0058] Scan the packaging of agricultural products after they are packaged, establish three-dimensional graphic data of the products, enter the electronic files and form the original data of agricultural product packaging; scan the packaging of agricultural products during the warehousing process, and compare the packaging data scanned during the warehousing process with the original data; determine the packaging type of agricultural products, obtain key image features of agricultural product packaging, extract key image features of the packaging data scanned during the warehousing process and key image features of the original data, compare the two key image features, and determine whether the packaging integrity is lower than a threshold.

[0059] In the packaging stage of agricultural products, the supplier of agricultural products first scans the package and provides 3D image data. The cloud server extracts key information based on the package data, such as the size of the package and the key image features of the package, and uses it to analyze, identify, and retain the category and 3D image data of the package. In the warehousing stage, after scanning the package again, the 3D image data of the package is also obtained. Similarly, the category of the package is automatically determined by the cloud server. By scanning both sides, the basic information of the package can be obtained, and whether the package is damaged can be automatically determined based on the category of the package.

[0060] Preferably, the key image features include, for example, the image features of the corners of the hard outer packaging and the image features of the main extension surface; for example, the image features of the surface lines of the soft packaging. It can be used to determine whether the packaging has bumps, wear, scratches, leaks, etc.

[0061] In addition, the transportation time of agricultural products, that is, the time from picking, packaging, logistics and warehousing, all need to be strictly controlled. Otherwise, for example, vegetables and fruits may be at risk of corruption. Since fruits and vegetables are difficult to store, they have a great impact on consumers' consumption experience. At the same time, packaged fruits and vegetables cannot be unpacked for inspection, so it is particularly important to control logistics time. Therefore, the inspection method is as follows: establish a time limit threshold for agricultural product transportation; scan the graphic label on the agricultural product packaging when the agricultural product is put into storage, and judge the actual time of agricultural product transportation based on the time when the original packaging image is entered into the electronic file; compare the actual time of agricultural product transportation with the agricultural product transportation time limit threshold. If it exceeds the agricultural product transportation time limit threshold, the agricultural product is defined as a product to be inspected.

[0062] Through the above methods, the quality of the product can be guaranteed to the greatest extent. If any problems are found, they can be traced back to the source. Consumers can also obtain the full production information of the product, providing a better service experience.

[0063] Example 2

[0064] At the same time, this embodiment also provides an inspection system for agricultural products in the storage process, specifically, Figure 2-Figure 6 As shown, this embodiment proposes a system combining the Internet of Things with agricultural product traceability, which can correspond to the above-mentioned method for combining the Internet of Things with agricultural product traceability, including

[0065] like Figure 2 and Figure 3 As shown, a first product conveying line 10; a packaging inspection device 11, which is set up at the input end of the first product conveying line 10, and the packaging inspection device 11 is used to scan the packaging image of the agricultural product;

[0066] A first product blocking device 12 is arranged on the first product conveyor line 10 and is located behind the packaging inspection device 11. The first product blocking device 12 is used to selectively block the products conveyed by the first product conveyor line 10 from entering the second product conveyor line 20; the second product conveyor line 20 is arranged adjacent to the first product conveyor line 10, and the input end of the second product conveyor line 20 is aligned with the first product blocking device 12; a first graphic label scanning device 21 is arranged on the second product conveyor line 20, and the first graphic label scanning device 21 is used to scan the graphic labels of the products conveyed on the second product conveyor line 20; a main control mechanism is signal-connected to the packaging inspection device 11, the first product blocking device 12, and the first graphic label scanning device 21 respectively, and is used to obtain the packaging image of the agricultural product. The main control mechanism is used to send the execution action quality to the first product blocking device 12 when the product packaging integrity is lower than the threshold value, and block the corresponding agricultural product from entering the second product conveyor line 20, and obtain the label image scanned by the first graphic label scanning device 21.

[0067] The second product conveyor line 20 is composed of two independent conveyor mechanisms, and the output end of the previous conveyor mechanism is adjacent to the input end of the latter conveyor mechanism. A second graphic label scanning device 22 is arranged at the interval between the two conveyor mechanisms, and the second graphic label scanning device 22 is connected to the main control mechanism signal.

[0068] In the second technical solution, preferably, the first product blocking device 12 includes a flipping drive device and a plate-shaped terminal, and the driving end of the flipping drive device is installed with the plate-shaped terminal so that the plate-shaped terminal drives the agricultural products to flip or rotate.

[0069] When the agricultural products enter the first product conveyor line 10, the packaging inspection device 11 inspects the packaging of the agricultural products. If the inspection is qualified, the first product blocking device 12 is retracted. If the inspection is unqualified, the first product blocking device 12 controls the baffle 126 to enter the first product conveyor line 10, as shown in the state of baffle 126A. The baffle 126 can provide a guiding effect to block the products on the first product conveyor line 10, so that the products enter the second product conveyor line 20. The first graphic label scanning device 21 on the second product conveyor line 20 scans the graphic label attached to the surface of the agricultural products to complete the traceability of the products. In some cases, because the label is pressed under the product, the second graphic label scanning device 22 can provide a scan of the graphic label under the agricultural product.

[0070] The first product blocking device 12 is a device that needs to be described in detail in this invention. In some cases, another packaging inspection device 11 can be set at the tail end of the first product conveying line 10 to inspect the lower packaging of agricultural products, especially for paper tape and plastic packaging. Therefore, the first product blocking device 12 can be used to turn over the agricultural products, and then the second packaging inspection device 11 can be used to scan the items.

[0071] The first product blocking device 12 includes a rotation drive device 121, and the rotation end of the rotation drive device 121, that is, the first rotating shaft 122, extends upward. The rotation drive device 121 is arranged on the side of the first product conveying line 10. The first rotating shaft 122 is provided with a guide mechanism 124 arranged along the axial direction of the first rotating shaft 122. The upper end of the first rotating shaft 122 is provided with a vertical drive mechanism 123, which can be a servo electric cylinder or a screw slider mechanism. The protruding end of the vertical drive mechanism 123 is arranged downward, and the protruding end of the vertical drive mechanism 123 is connected to a slider and a flip drive device 125. The slider and the flip drive device 125 are installed on the guide mechanism 124. The slider and the flip drive device in the flip drive device 125 are connected to the baffle 126. Therefore, the baffle 126 can be driven by the rotation drive device 121 to rotate around the axis of the first rotating shaft 122, and can also be driven by the flip drive device to be horizontally flipped.

[0072] like Figure 6 As shown, by combining the rotation drive device 121, the vertical drive mechanism 123 and the guide mechanism 124, the baffle 126 can perform a conforming movement, that is, the baffle 126 can be tilted and lowered so that the lower end of the baffle 126 is in contact with the conveying surface of the first product conveyor line 10, as shown in the state of the baffle 126B. The agricultural products can be conveyed to the top of the baffle 126 through the first product conveyor line 10, and conforming actions are performed according to predetermined instructions to drive the agricultural products to rotate a certain angle, or completely flip over, and then the items are scanned by the second packaging inspection device 11.

[0073] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
