Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable traceability technology, specifically a fruit and vegetable traceability system, traceability method, and its application. Background Technology

[0002] With the improvement of people's living standards and the enhancement of food safety awareness, buyers have increasingly higher demands for transparency in the entire process of fruit and vegetable planting, harvesting, packaging, and testing. Fruit and vegetable traceability technology has emerged as a result. Existing fruit and vegetable traceability systems mostly use label identification linked to cloud data, but this has many drawbacks: First, labels are easily tampered with, replaced, or reused, leading to distorted traceability information; second, traceability data is mostly manually entered, lacking objective evidence chains such as images, time, and location, resulting in low credibility; third, the packaging process lacks effective anti-counterfeiting measures, making it prone to problems such as fruit and vegetable swapping and repackaging, failing to guarantee the consistency between traceability information and the actual fruit and vegetables; fourth, the traceability process is disconnected from the testing process, making it difficult for buyers to directly obtain information on the quality of the fruit and vegetables, thus hindering their peace of mind.

[0003] Furthermore, existing traceability systems often fail to effectively link planting site information, making it impossible to accurately trace the origin of fruits and vegetables. Moreover, the lack of effective process monitoring and information correlation methods during bulk harvesting and packaging further reduces the accuracy and reliability of traceability. Therefore, there is an urgent need for a fruit and vegetable traceability solution that can achieve end-to-end anti-counterfeiting, data verification, and integrated testing and traceability to address the aforementioned problems in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fruit and vegetable traceability system, traceability method and its application, so as to realize the traceability of fruits and vegetables from planting plot, harvesting, packaging, testing to purchaser inquiry, ensure the authenticity, immutability and verifiability of traceability information, and enhance the purchaser's trust in the safety of fruits and vegetables.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fruit and vegetable traceability system includes: a disposable packaging container, a recording terminal, a cloud platform, and a mobile terminal; wherein: The cloud is used for storing and processing data; A disposable packaging container is used to package fruits and vegetables in a single use. The disposable packaging container cannot be opened non-destructively after the opening is closed. The packaging structure or the packaging container must be damaged to remove the fruits and vegetables inside. The disposable packaging container has a unique identifier. The recording terminal captures images of the process of harvesting fruits and vegetables and / or packing them into disposable packaging containers, identifies the unique identifier on the disposable packaging container, and records time and / or location information. It communicates with the cloud to upload the unique identifier information, image information, time information and / or location information to the cloud and associates them with each other. The mobile terminal is used to identify the unique identifier on the disposable packaging container and read the information associated with the unique identifier in the cloud, so as to realize the traceability of fruits and vegetables in the disposable packaging container.

[0006] Preferably, the recording terminal includes an image acquisition module, a recognition module, a time module, and a communication module; wherein: The image acquisition module is used to acquire image information; The identification module is used to identify the unique identifier on the disposable packaging container either through the image acquisition module or directly. The time module records the time information for image acquisition and / or identification of unique identifiers; The communication module is used for data communication with the cloud.

[0007] Preferably, the recording terminal further includes a location module for recording location information during image acquisition and / or identification of unique identifiers.

[0008] Preferably, it also includes a fixed land plot sign, which is fixed to the fruit and vegetable planting plot and is equipped with a unique identifier that can be identified by a recording terminal; the unique identifier records or binds the information of the fruit and vegetable planting plot, and the plot information includes at least location information.

[0009] Preferably, it also includes a panoramic video monitoring module for recording the picking and / or packaging process, which has a built-in second time and / or second location module and a second communication module. The second communication module uploads video information, time information and / or location information to the cloud and associates them with each other.

[0010] A traceability method for a traceability system as described above includes the following steps: S1. Workers use a recording terminal to capture images of fruits and vegetables being packed into disposable packaging containers and the completion of the sealing of the disposable packaging containers, and record time information and / or location information. S2. Before, during, and / or after step S1, the unique identifier on the disposable packaging container is identified and read by the recording terminal; S3. The recording terminal uploads the image information, time information and / or location information, and the unique identification information on the disposable packaging container to the cloud and associates them with each other; S4. Purchasers or testing agencies can identify the unique identifier on the disposable packaging container through a mobile terminal, read cloud data, and view the information associated with the unique identifier, thereby enabling traceability of the fruits and vegetables inside the disposable packaging container.

[0011] Preferably, before and / or after step S1, workers read the unique identification information of the fixed signboard of the picking plot through a recording terminal. The recording terminal can upload the information to the cloud and associate it with the unique identification information on the disposable packaging container in step S1.

[0012] Furthermore, during the bulk bagging process of fruits and vegetables, the workers need to periodically and / or after completing the sealing operation of a predetermined number of packaging containers, read the unique identification information of the fixed signboard of the picking plot through the recording terminal.

[0013] Preferably, this also includes capturing images of the harvesting process using a recording terminal and uploading them to the cloud.

[0014] Preferably, before step S1, the method further includes capturing images of the unpackaged disposable containers without fruits and vegetables using a recording terminal.

[0015] An application based on the traceability method described above is used to combine the sampling and testing of the same type of fruits and vegetables from the same plot of land, batch harvesting and packaging, and buyer traceability, including the following process: S1: Sampling and testing: Using the traceability method described above, the fruit and vegetable samples from the designated plots are harvested and packaged, and the fruit and vegetable samples packaged in disposable containers are sent to the testing institution for testing. The testing agency uploads the testing information and results, along with the unique identifier of the disposable packaging container for the submitted sample, to the cloud and links them together. S2: Batch Harvesting and Packaging: If the fruit and vegetable samples submitted for testing in step S1 pass the test, workers will harvest and package the same type of fruit and vegetables from the same plot of land as the above-mentioned samples within a set time using the traceability method described above; the cloud will associate the unique identification information of the disposable packaging container after harvesting and packaging with the test information and result information uploaded in step S1. S3: Buyer traceability: After receiving the packaged fruits and vegetables, the buyer can identify the unique identification information on the disposable packaging container through a mobile terminal, and read the information associated with the unique identification information from the cloud to achieve traceability of the fruits and vegetables in the disposable packaging container.

[0016] Another application based on the traceability method described above combines the batch harvesting and packaging, sampling and inspection, data association, and buyer traceability of the same type of fruits and vegetables from the same plot of land, including the following process: S1: Batch harvesting and packaging: Workers harvest and package the same type of fruits and vegetables from the same plot of land in batches using the traceability method described above; S2: Sampling and Inspection: The testing personnel randomly or designated fruit and vegetable samples from the batch-packaged fruits and vegetables for testing, and upload the test information and results information, as well as the unique identification information of the corresponding disposable packaging container, to the cloud and link them together.

[0017] S3: Data Association: The cloud will associate the detection information and result information uploaded in step S2 with the unique identification information of all single-use packaging containers after harvesting and packaging uploaded in step S1; S4: Buyer traceability: After receiving the packaged fruits and vegetables, the buyer can identify the unique identification information on the disposable packaging container through a mobile terminal, and read the information associated with the unique identification information from the cloud to achieve traceability of the fruits and vegetables in the disposable packaging container.

[0018] Compared with the prior art, the beneficial effects of the present invention are: The use of disposable destructive packaging containers, which cannot be opened non-destructively after being sealed, physically eliminates the problems of fruit and vegetable swapping, secondary packaging, and reuse of labels, ensuring the consistency between traceability information and actual fruits and vegetables. The entire process of recording and packaging images by the terminal is recorded and associated with unique identifiers, time, and location information to form a complete and objective chain of evidence. This avoids the subjectivity and unreliability of manually entered data and improves the credibility of traceability information. By setting up fixed identification signs for the plots and binding them with plot information, and using a displacement detection module to prevent the plot information from being tampered with, accurate traceability of fruit and vegetable production areas has been achieved. By integrating testing and traceability, two implementation processes can be selected according to actual needs. Buyers can directly check fruit and vegetable testing information through mobile terminals, which further enhances buyers' trust. The system has a complete structure and clear logic. The traceability method is simple and easy to implement. It has a wide range of applications and can be used for large-scale planting, harvesting, packaging and traceability of various fruits and vegetables. It has strong practicality and promotional value. The panoramic video monitoring module further improves process monitoring, enriches the traceability evidence chain, and enhances the reliability of the traceability system. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of the packaging bag of the present invention. Detailed Implementation

[0020] This invention uses a disposable encapsulation container (physical layer) combined with a set of on-site image binding system (data acquisition layer) to realize the reliable uploading of source information to the blockchain (data layer), and ultimately serves quality verification and consumer inquiry (application layer).

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] Please see Figure 1 In this embodiment of the invention, a disposable packaging container for fruit and vegetable picking includes a bag body 1 with an opening and a restraining member 2 disposed at the opening of the bag body 1 for tightening the opening. The restraining member 2 is configured such that when the restraining member 2 tightens the opening of the bag body 1, the items inside the bag body 1 can only be taken out by breaking the bag body 1 or the restraining member 2.

[0023] The bag body 1 is made of transparent plastic film, and its inner wall is made hydrophilic through physical or chemical treatment to prevent water mist formation and maintain transparency. Specifically, this treatment can be to spray a transparent hydrophilic coating on the surface of the bag body 1. On the other hand, the bag body 1 is provided with ventilation holes 4 to ensure that the inside and outside of the bag body 1 can be ventilated, so as to prevent the water inside the bag body 1 from being unable to drain and condensing on the inner wall of the bag body 1, forming water mist or water droplets, which would affect the transparency of the bag body 1 or the quality of fruits and vegetables.

[0024] Furthermore, a unique identifier may be provided on the bag body 1 and / or the restraint 2, and the information of the unique identifier shall be identified by the image acquisition module when the fruits and vegetables are harvested. The unique identifier includes, but is not limited to, one or more of the following: barcode, QR code, digital code, symbol code, NFC, and radio frequency identification tag, preferably a QR code.

[0025] The unique identifier can effectively prevent the binding member 2 from being maliciously damaged, removed and replaced, thereby avoiding the tampering behavior of re-tightening the opening of the bag body 1 with a new binding member 2 after the original fruits and vegetables are taken out. It realizes traceability verification of the integrity and authenticity of the packaging and improves anti-counterfeiting and security capabilities.

[0026] The restraint 2 is a one-time pull-tight seal, specifically including a locking rope 21 and a one-way locking mechanism 22; one end of the locking rope 21 is fixed to the one-way locking mechanism 22, and the other end goes around the opening of the bag body 1 and passes through the one-way locking mechanism 22; the one-way locking mechanism 22 allows the locking rope 21 to pass through in one direction to tighten the opening of the bag body 1.

[0027] Specifically, one end of the locking rope 21 is permanently fixed inside the one-way locking mechanism 22 by injection molding.

[0028] The locking cord 21 is made of one or more of metal wire, polymer fiber, or plastic material; the one-way locking mechanism 22 and the locking cord 21 together constitute a commercially available one-time pull-tight irreversible seal. Once the locking cord 21 is locked, it cannot be opened unless the seal itself is damaged, thus ensuring the uniqueness and anti-counterfeiting of the seal.

[0029] The locking cord is made of a material with shape memory properties. After passing through the opening of the bag body 1, it can open the opening when it is not tied, making it convenient to bag fruits and vegetables. Specifically, the locking cord 21 is preferably made of plastic, with a circular cross-section and an outer diameter of not less than 2mm. Example

[0030] A specific form of connection between the restraint member 2 and the bag body 1 is provided.

[0031] The opening of the bag body 1 is provided with a drawstring track 3 for the restraint member 2 to pass through, and the drawstring track 3 is provided with at least one notch.

[0032] Specifically, the drawstring track 3 can be formed by hot pressing the opening of the bag body 1 downwards, or by directly fixing a rope-like component. In this invention, it is preferred to form it by hot pressing the opening of the bag body 1 downwards.

[0033] Furthermore, there are two notches, which are respectively set on both sides of the opening of the bag body 1. When making the drawstring track 3 of this packaging container, the two sides of the bag body 1 are hot-pressed respectively, which can reduce the forming difficulty of the drawstring track 3.

[0034] The restraint piece 2 passes through one of the notches into the drawstring track 3 and goes around the edge of the bag opening, extending out from the same notch to tighten the opening of the bag body 1. Example

[0035] Provide the specific molding form of bag body 1.

[0036] The bag body 1 is quadrilateral, and the side opposite to the side with the opening is a continuous side where the front and back fabrics of the bag body 1 are integrally connected.

[0037] The above structural design brings significant anti-tampering advantages: if someone attempts to illegally obtain the sample inside the bag, even if they cut the bag along the continuous edge 1, any attempt to re-glu or heat-press will leave traces that are visible to the naked eye or detectable by professional equipment (such as glue marks, wrinkles, and changes in material properties). This makes it easy to identify that the sealed bag has been illegally opened, fundamentally eliminating the possibility of tampering or sampling by damaging the edge, and greatly enhancing the credibility and evidentiary value of the sampling results.

[0038] The two opposite sides adjacent to the continuous edge can be fused and sealed by hot pressing. After the opening of the bag body 1 is tightened, the two opposite sides near the bag opening will show an irregular folded state. If anyone tries to cut the bag body 1 from the side, the cut will inevitably penetrate through these complex folds, forming an irregular tear that is difficult to repair. Example

[0039] Other settings that provide a unique identifier.

[0040] In addition to the above forms, the unique identifier in this invention can also be a separate component placed inside the bag body 1 after the opening is tightened, or directly connected to the surface of the bag body 1. When the bag opening of the bag body 1 is in a tightened state, separating the unique identifier from the restraint 2 or the bag body 1 will inevitably damage the unique identifier, the restraint 2, or the bag body 1. Example

[0041] A fruit and vegetable traceability system and method based on the above-mentioned packaging containers are provided.

[0042] This includes: disposable packaging containers, recording terminals, cloud platforms, and mobile terminals; among which: The cloud uses cloud servers to store data, including unique identification information, image information, time information, location information, land parcel information, and detection information. It has data encryption, backup and fast read functions to ensure data security and query efficiency. The disposable packaging container described in Examples 1-4 is used to achieve disposable packaging of fruits and vegetables. The disposable packaging container cannot be opened non-destructively after the opening is closed. The packaging structure or the packaging container must be damaged to remove the fruits and vegetables inside. The disposable packaging container has a unique identifier, preferably a QR code. The recording terminal captures images of the process of harvesting fruits and vegetables and / or packing them into disposable packaging containers, identifies the unique identifier on the disposable packaging container, and records time and / or location information. It communicates with the cloud to upload the unique identifier information, image information, time information and / or location information to the cloud and associates them with each other. The mobile terminal, such as a mobile phone or tablet, is equipped with a dedicated traceability query APP. By scanning the code on the disposable packaging container, the unique identifier can be identified, and a query request can be sent to the cloud to read all traceability data associated with that unique identifier. The data is then displayed to the user in the form of pictures, text, and videos, making it easy for the user to view quickly and enabling traceability of fruits and vegetables inside the disposable packaging container.

[0043] The recording terminal includes an image acquisition module, a recognition module, a time module, and a communication module; wherein: The image acquisition module uses a head-mounted, shoulder-mounted, or chest-mounted camera device to acquire image information, which can be in the form of video and / or photographs. The identification module is used to identify the unique identifier on the disposable packaging container either through the image acquisition module or directly. For example, if the unique identifier is a QR code, it can be identified through the image acquisition module. The time module (real-time clock module) records the time information for image acquisition and / or identification of unique identifiers; Communication modules (4G / 5G / Bluetooth / WIFI, etc.) are used for data communication with the cloud.

[0044] The recording terminal also includes a location module for recording location information during image acquisition and / or identification of unique identifiers, wherein the location module includes one or more of a GPS module, a Beidou module, or a base station positioning module.

[0045] It also includes fixed land plot signs, which are fixed to the fruit and vegetable planting plots and are equipped with unique identifiers that can be identified by the recording terminal; the unique identifiers record or bind the information of the fruit and vegetable planting plots, and the plot information includes at least location information.

[0046] Specifically, the fixed plot markers are made of stainless steel or plastic and are fixed in a conspicuous position on the fruit and vegetable planting plots, making them resistant to damage and movement. Each marker has a unique, readable identifier (barcode, QR code, or NFC, etc.) that is linked to the plot number, latitude and longitude coordinates, type of fruit and vegetable planted, and planting time. The markers also have a built-in displacement detection module to detect whether the marker itself has been moved after being fixed. This module can transmit displacement information to the recording terminal via wireless communication when the terminal approaches, triggering a displacement alarm. Furthermore, the system is compatible with planting bases that do not have fixed plot markers. In such scenarios, the GPS positioning module of the recording terminal is used to collect harvesting and packaging location information, combined with a preset range of latitude and longitude coordinates for the same plot, to determine if the plants are on the same plot. This eliminates the need for additional markers, reducing the investment costs for the planting base.

[0047] In addition, this traceability system also includes a panoramic video monitoring module for recording the harvesting and / or packaging process. It can use a high-definition spherical camera, which is installed in the harvesting and packaging operation area. It has a built-in second time and / or second location module and a second communication module. It can collect panoramic images of the entire harvesting and packaging process in real time, record the time and location information of image acquisition, and upload them to the cloud through the second communication module. It is associated with the unique identification information of disposable packaging containers harvested and packaged in the same plot and within the same time period to form a more comprehensive process monitoring evidence chain.

[0048] The fruit and vegetable traceability method based on this traceability system includes the following steps: S1. Workers use a recording terminal to capture images of fruits and vegetables being packed into disposable packaging containers and the completion of the sealing of the disposable packaging containers, and record time information and / or location information. S2. Before, during, and after step S1, the unique identifier on the disposable packaging container is identified and read by the recording terminal; S3. The recording terminal uploads the image information, time information and / or location information, and the unique identification information on the disposable packaging container to the cloud and associates them with each other; S4. Purchasers or testing agencies can identify the unique identifier on the disposable packaging container through a mobile terminal, read cloud data, and view the information associated with the unique identifier, thereby enabling traceability of the fruits and vegetables inside the disposable packaging container.

[0049] This traceability method also includes, before and / or after step S1, workers reading the unique identification information of the fixed signboard of the picking plot through a recording terminal. The recording terminal can upload this information to the cloud and associate it with the unique identification information on the disposable packaging container in step S1.

[0050] During the bulk bagging of fruits and vegetables, the workers need to periodically and / or after completing the sealing of a predetermined number of packaging containers, read the unique identification information of the fixed signboard of the picking plot through the recording terminal.

[0051] It also includes capturing images of the harvesting process using a recording terminal and uploading them to the cloud.

[0052] It also includes capturing images of the unpackaged, unfilled containers of fruits and vegetables using a recording terminal before step S1. Example

[0053] This embodiment provides an application of the fruit and vegetable traceability method in Embodiment 5, which combines the sampling and testing of the same type of fruit and vegetable from the same plot, batch harvesting and packaging, and buyer traceability, including the following process: S1: Sampling and testing: Using the traceability method described in Example 5, the fruit and vegetable samples from the designated plots are harvested and packaged, and the fruit and vegetable samples packaged in disposable containers are sent to the testing institution for testing. If the test results are satisfactory, the testing organization will upload the test information and results, as well as the unique identifier of the disposable packaging container of the corresponding sample, to the cloud and link them together. This test information includes information about the testing organization, the type of fruit and vegetable, the information of the fruit and vegetable producer, and images of the testing process. S2: Batch Harvesting and Packaging: After receiving the qualified test results of the fruit and vegetable samples, workers shall, within a set time (calculated from the harvesting time of the fruit and vegetable samples in step S1, preferably 3 days), harvest and package the same type of fruit and vegetables from the same plot of land as the above-mentioned fruit and vegetable samples using the traceability method described in Example 5; the cloud shall associate the unique identification information of the disposable packaging container after harvesting and packaging with the test information and result information uploaded in step S1; if the set time is exceeded or the harvesting and packaging is carried out in different plots, the cloud shall refuse to establish an automatic association with the test information in step S1 and prompt that resampling and testing are required; S3: Buyer traceability: After receiving the packaged fruits and vegetables, the buyer can identify the unique identification information on the disposable packaging container through a mobile terminal, and read the information associated with the unique identification information from the cloud to achieve traceability of the fruits and vegetables in the disposable packaging container.

[0054] After the fruits and vegetables are harvested and packaged in batches in step S2, a number of packaged fruits and vegetables are randomly selected for testing to further ensure their quality and safety. Example

[0055] This embodiment provides another application based on the fruit and vegetable traceability method in Embodiment 5, which combines the batch harvesting and packaging, sampling and inspection, data association, and buyer traceability of the same type of fruits and vegetables from the same plot of land, including the following process: S1: Batch harvesting and packaging: Workers harvest and package the same type of fruits and vegetables from the same plot of land in batches using the traceability method described in Example 5; S2: Sampling and Inspection: The testing personnel randomly or designated fruit and vegetable samples from the batch-packaged fruits and vegetables for testing, and upload the test information and results information, as well as the unique identification information of the corresponding disposable packaging container, to the cloud and link them together.

[0056] S3: Data Association: The cloud will associate the detection information and result information uploaded in step S2 with the unique identification information of all single-use packaging containers after harvesting and packaging uploaded in step S1; S4: Buyer traceability: After receiving the packaged fruits and vegetables, the buyer can identify the unique identification information on the disposable packaging container through a mobile terminal, and read the information associated with the unique identification information from the cloud to achieve traceability of the fruits and vegetables in the disposable packaging container.

[0057] In Examples 6 and 7, the criteria for determining whether a plot of land is the same include any one or two of the following: (a) Match the unique identifiers of the fixed land parcel signs read by the recording terminal. If they match, they are determined to be the same land parcel. (b) The location information of picking and / or packaging collected by the terminal location module is used to make a judgment. If the location information falls within the preset coordinate range of the same plot, it is determined to be the same plot.

[0058] Specifically, the recording terminal uploads the current packaging location information in real time; the cloud determines in real time whether the current packaging location is in the same plot as the sample to be tested based on the judgment criteria; if it is determined that they are not in the same plot, the cloud immediately sends a warning message to the recording terminal and refuses to associate the unique identifier of the batch of packaging containers with the detection information in step S1, and at the same time the recording terminal stops the current packaging operation or refuses to upload the packaging data. If the land parcel is determined to be the same, the cloud platform will allow the encapsulation operation to continue. It should also be noted that the packaging container, traceability system and method in this application can also be used for testing the soil or water quality of planting bases.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the contents not described in detail in this specification are all prior art known to those skilled in the art.
