Description

Pesticide Residue Fast Screening Blockchain System

The present invention relates to a block chain system for rapid screening of pesticide residues, in particular to a system for managing the results of fast screening of pesticide residues by virtue of the non-tamperable nature of the block chain.

In order to maintain the yield and quality of crops, the application of pesticides is often one of the main methods of plant protection. The use of pesticides has led to many problems. In addition to environmental pollution, the greater impact is the impact of pesticide residues on human health. Implementing pesticide testing on crops and avoiding highly toxic pesticide residues is an urgent first-line demand.

The government has established the chemical method as the standard inspection method for pesticides. The chemical method has disadvantages that are difficult to improve, such as expensive equipment, high inspection fees, long testing time, and long reporting time. However, the expiry date of agricultural products must be considered. Therefore, when the inspection report of pesticide exceeding the standard is completed by chemical method, the agricultural products are often sold out because of the expiry date, and even have entered the mouth of consumers. In recent years, rapid pesticide screening methods such as biochemical methods and mass spectrometry have been gradually derived, which can present the nature of pesticide residues and greatly increase the amount of inspection. However, the quantitative accuracy of quick screening is not as good as that of chemical methods, so it is difficult to serve as a direct basis for administrative penalties. When the government is unable to impose penalties accordingly, producers, distributors and distributors will not regard the results of the quick screening as an important condition for buying and selling products.

On the other hand, the inspection work of grass-roots inspection stations set up in vegetable and fruit markets and farmers' associations Usually it is a stand-alone operation without multi-machine network integration, and inspection data must be manually recorded and uploaded. During the recording process, there is a possibility of omission or tampering of data, which leads to the failure of the random inspection work on the inspection side, and the validity of the data is easily questioned.

Therefore, the market needs a fast pesticide screening platform with credibility and authentic data, so that consumers have an open and credible channel for querying pesticide residues in agricultural products.

When opening the agricultural product filing module 2, there is a default form for easy filling in according to the content. The agricultural product filing module 2 can be input by the front-line operator of the inspection station, or it can cooperate with the producer, and the producer can fill in part of the information by himself. News. Even, the agricultural product filing module 2 has an image recognition function; after the image is obtained by the image capture device, the agricultural product filing module 2 performs image recognition to automatically generate the name or code of the agricultural product. Product barcodes can be one-dimensional codes, two-dimensional codes or quick response matrix codes, which can be displayed on the mobile phone interface or printed out, or even printed as stickers to be pasted on agricultural products, agricultural product packaging or agricultural product-related documents.

The detection station host 3 and the agricultural product filing module 2 are coupled through the pesticide detection cloud device. The detection station host 3 and the agricultural product filing module 2 can be operated at different places and times, but while the quick screening detects pesticide residues, the inspection station host 3 can present the product information of the detection target, and the corresponding information will be displayed immediately after the detection Product information and pesticide residue index upload.

The unit management information includes a preset number of random inspections for a production and marketing unit. The pesticide detection cloud device further calculates a screening test based on the preset number of random inspections and an actual number of random inspections Execute the achievement rate, and encrypt and upload to the agricultural blockchain platform. For example, the unit expects to conduct sampling inspections every three batches of agricultural products, but in fact conducts sampling inspections every five batches; or conducts random inspections of ten batches of agricultural products every week, but only randomly inspects two batches per week. The above situations will lead to the success rate of screening implementation, which can enable the management to urge grassroots operations to implement random inspections, and also allow consumers to know whether the manufacturer has implemented the declared quality control goals.

The pesticide detection cloud device 1 may also include a unit management interface (not shown in the figure), which is used for management by manufacturers, consignors, distributors, and food vendors. It can query the upstream screening results of agricultural products during source management, or When doing factory management, the screening progress of multiple agricultural products can be sorted out. The unit management interface can also allow the unit to explain the status of the final destruction or return of agricultural products with excessive pesticide residues for continuous tracking.

In a specific embodiment, the pesticide residue fast screening detection module 5 or the detection station host 3 When screening agricultural products, a sampling location data and a sampling time data are generated, and through the testing station host 3 and the pesticide detection cloud device 1, the sampling location data and sampling time data are collected into product pesticide residue management information.

The printed product barcode can be attached to the agricultural product and moved with the agricultural product. The printer 8 can be wired to the host computer 3 of the testing station, or wirelessly connected to the mobile terminal device 20 or the pesticide testing cloud device 1 to receive printing signals and content.

In addition, the code scanning module 4 can also be a mobile application installed on a mobile terminal device 40 , and the code scanning module 4 is coupled to the detection station host 3 through the communication function of the mobile terminal device 40 . The mobile terminal device 40 and the mobile terminal device 20 can be the same group of mobile terminal devices, and the agricultural product filing module 2 and the code scanning module 4 can be different applications on the same group of mobile terminal devices, or they can be the same application program The different functions provided.

The code scanning module 4 can also be a common dedicated hand-held code scanner, and the other end of the code scanner is wired or wirelessly connected to the host computer 3 of the testing station.

The following example illustrates the implementation method of the pesticide residue fast screening blockchain system S. Producers of agricultural products can use the mobile terminal device 20 to use the agricultural product filing module 2 to create part of product information and upload it to the pesticide detection cloud device 1 . Then, when the agricultural product arrives at the testing station, the filing operator holds the mobile terminal device 20 and also uses the agricultural product filing module 2 to create part or all of the product information for the agricultural product, and uploads it to the testing station host 3 or the pesticide testing cloud device 1 . Producer of Agricultural Products Both the agricultural product filing module 2 and the filing operator can operate the agricultural product filing module 2 for a single agricultural product, but they have different system operation permissions. Producers of agricultural products can only create general information such as images of agricultural products and names of agricultural products; in addition to general information, filing operators can also create process information such as collection dates, and create physical product barcodes for this batch of agricultural products.

Next, the inspector randomly selects a small amount of agricultural products to enter the inspection area, and uses the code scanning module 4 in the mobile terminal device 40 to scan the barcode of the product. After scanning, the code scanning module 4 uploads the code scanning signal to the pesticide testing cloud device 1, and the product information is called out from the testing station host 3 or the pesticide testing cloud device 1, and is presented on the testing station host 3, so as to facilitate random inspection by inspectors. Information on agricultural products and products. After the comparison is completed, the random inspector can carry out the next step of pesticide screening. The system operation authority of the random inspection inspector is also different from that of the agricultural product producer or the filing operator. The random inspection inspector can bind and operate the pesticide residue rapid screening detection module 5 through the mobile terminal device 40, but cannot change the pesticide residue rapid screening detection module. 5. The output value of the pesticide residue index, which will be automatically uploaded to the pesticide detection cloud device 1.

Due to the different system operation rights of each role, the pesticide residue rapid screening blockchain system S further has an operator identification module (not shown) coupled with a mobile terminal device, a pesticide residue rapid screening detection module, a code scanning module or At least one of the detection station hosts. The operator identification module can be used for user account login identification, requiring specific numbers or graphic passwords to log in to different accounts. The operator recognition module can also be a face recognition module, an iris recognition module, a voice recognition module, a fingerprint recognition module, a signature recognition module, a palmprint recognition module, a finger vein recognition module and other physiological feature recognition methods. After the identification, bind the random tester's information (name, affiliation, etc.) with the current equipment, so that the operator is responsible for the content of the operation.

Operators can also query the history of agricultural products previously established through the inspection station host 3 Data, the query and presentation items include the agricultural products whose product information has been established by the testing station, the agricultural products whose pesticide residue index has been tested by this testing station, the agricultural products whose pesticide residue index has been tested by all testing stations in the region, and all agricultural products produced by a certain producer . The queried historical data can be divided according to the authority of the operator.

In actual application, the filing work and testing work in the testing station can be carried out by the same operator at the same time and at the same place. However, this system can also support different operators to carry out filing work and inspection work at different times and locations. At this time, it is more conducive to the personnel field management of the inspection station and the elimination of human operation factors.

The product pesticide residue inspection report must be an anti-counterfeit report, so it is necessary to rely on signature encryption to prevent the risk of the report being tampered with, in order to highlight the orthodoxy and consistency of the system. In the encryption process, multiple inspection station hosts 3 jointly use multiple signature engines. Each signature engine generates a system signature for the product pesticide residue inspection report based on the same system private key. Signature of pesticide residue inspection report. The pesticide detection cloud device 1 includes a signature analysis engine, which checks the system signature on the received product pesticide residue inspection report according to the system public key paired with the system private key.

Agricultural blockchain platform 6 can only If there are relevant materials on pesticide testing, we can also provide other services such as agricultural contracts and payment transactions.

Finally, the consumer scans the product barcode attached to the agricultural product through his mobile device, and is linked to the consumer query interface 12 of the agricultural product, where he can see the real pesticide quick screening data of the agricultural product. Alternatively, the consumer has not yet seen the agricultural product and the product barcode, but is connected to the pesticide detection cloud device 1 through the network to search for the designated agricultural product; the consumer query interface 12 presents multiple terminal sales stores of the agricultural product, allowing consumers to select Go to any store to buy the produce you want. Even, consumers connect to the pesticide detection cloud device 1 through the network to search for a designated channel; the consumer inquiry interface 12 presents all the agricultural products sold in the channel, allowing consumers to refer to all the agricultural product options to decide whether to go to the store. Alternatively, the consumer can inquire through the consumer inquiry interface 12 the upstream quick screening results of the agricultural products purchased by catering operators such as group catering operators, restaurants, and beverage stores.
