Technical Field

[0001] The invention relates to a food safety rapid detection system, a sampling operation method and a sampling instrument. Background Art

[0002] Food safety rapid testing is an emerging industry. At present, food safety rapid testing rooms have begun to be built on a large scale, and the research and development of corresponding technical equipment is also underway. The process of food safety rapid testing includes detection task allocation, sampling, pre-processing, testing, and uploading of test results. Usually, the sampling process is carried out through a sampler. The sampling process includes information acquisition and sample acquisition. Information acquisition includes business information, sampling personnel information, sampling time and location information, sample information, etc. Sample acquisition is to obtain the sample itself, such as vegetables, meat, fish, etc. When the sampling personnel start sampling, they first enter the relevant information, then obtain the sample and put it into the sampling bag, then print the sampling QR code and part of the sampling information, and stick it on the front of the sampling bag. The information obtained by sampling is uploaded to the network server through the sampler.

The handheld sampler has an instant call function and realizes real-time transmission of data. Through functions such as taking pictures, recording, scanning, and printing, standardized sampling procedures and processes are realized, avoiding the need for samplers to collect tedious handwritten information to ensure the authenticity and standardization of the entire sampling link.

[0007] Furthermore, rapid testing sampling covers a wide range of areas, and many business premises require a large number of sampling operators, but the quality of sampling operators varies greatly, and standardized sampling operations lack the corresponding basic equipment;

[0008] In addition, due to the wide coverage of rapid testing, there are many testing methods and testing instruments involved, and the requirements for sampling are also different. Commonly used testing methods for rapid food safety testing include immunocolloidal gold method, chemical colorimetry, ELISA (Enzyme-Linked ImmunoSorbent Assay), bioluminescence method (Adenosine Triphosphate, referred to as ATP), PCR (Polymerase Chain Reaction), sensor method, infrared method, Raman spectroscopy, etc.; the corresponding instruments mainly include gold labeling instrument, multi-parameter biochemical rapid test instrument, enzyme labeling instrument, ATP fluorescence instrument, PCR detector, etc. Different methods and instruments have different sampling requirements.

[0009] In addition, in order to reduce food safety risks as much as possible, samples will be selected from parts that people usually eat or parts with the highest risk. Some samples are collected from the whole plant, some from roots, some from leaves, some from flesh, some from blood, some from urine, and so on.

[0010] Due to the above problems, how to help sampling operators to collect samples correctly, how to scientifically determine the sampling method based on the material and technical conditions of the rapid testing room, etc., are all problems that need to be solved. Summary of the invention

[0037] Figure 3The present invention is a sampling task help prompt information organization diagram. The sampling task help prompt information organization diagram is organized from three attributes such as sampling object, detection item and detection method. For example, for sampling object A, there are two detection items assigned, namely detection item a and detection item b. Each detection item corresponds to a variety of detection methods. For example, detection item a has available detection methods including detection method I, detection method II and detection method III. Different sampling objects, different detection items and different detection methods will have corresponding sampling help prompts. Through this prompt, the sampling personnel can be guided to collect samples correctly. The data can be stored in a database for acquisition and application by the sampler.

[0038] Figure 4 The basic flow chart for generating the sampling help prompt of the present invention. First, select the sampling object, such as celery, pork, etc.; then, according to the sampling object, follow Figure 3 According to the association diagram shown, the detection item corresponding to the sampling object is searched from the corresponding database, one is selected from the corresponding detection item and the detection method is selected; then, the sampling help prompt information corresponding to the sampling object, detection item and detection method is searched from the corresponding database, and the information is determined to be the sampling help prompt information displayed on the sampler; finally, the sampling personnel completes the sampling operation according to the sampling help prompt information displayed on the sampler.

[0039] Since the complexity of sampling operations varies for different sampling objects, some are simple and some are complex. For complex operations, a step-by-step prompt method can more effectively help sampling personnel complete the sampling operations. Figure 5 The basic flow chart of the step-by-step sampling help prompt generation of the present invention. First, select the sampling object, such as celery, pork, etc.; then, according to the sampling object, follow Figure 3 According to the association diagram shown, the detection item corresponding to the sampling object is searched from the corresponding database, and one is selected from the corresponding detection item and the detection method is selected; then, the sampling help prompt information corresponding to the sampling object, detection item and detection method is searched from the corresponding database, and the information is determined to be the sampling help prompt information displayed on the sampler. The sampling help prompt information is organized according to the sampling steps, and the sampling help prompt can be performed step by step; then, the sampling operation help information of the current step is displayed on the sampler according to the current step. In the process of interactive prompts, the system continuously identifies, judges or confirms whether the current sampling operation step is completed. If it has been completed, it enters the next step and displays the sampling operation help file. In this way, step by step, until the sampling personnel completes the sampling operation according to the sampling help prompt information displayed on the sampler.

[0040] The concept of the present invention is explained below in conjunction with a specific sampling process.

[0041] First, the food safety rapid inspection management platform 2 will assign inspection tasks to each rapid inspection room according to the sampling plan, such as "at XX merchant in XX market, leek pesticide residue detection". When assigning the inspection task, the platform will form sampling task information, such as "Inspector No. 1 of XX Rapid Inspection Room went to XX merchant in XX market to collect leek for pesticide residue detection, among which, the sampling object: leek; using step-by-step sampling help prompts, a total of 4 steps; Step 1: XXXX, step 1 sampling operation help information: XXXX; Step 2: XXXX, step 2 sampling operation help information: XXXX; Step 3: XXXX, step 3 sampling operation help information: XXXX; Step 4: XXXX, step 4 sampling operation help information: XXXX;...". After the above sampling task information is generated, after Inspector No. 1 logs in to the system through the sampler, the system will push the sampling information to the sampler. Figures 6 to 9 The interactive process of the sampling help information on the sampler is shown.

[0042] Figure 6 It is the interactive help information of step 1. Step 1 is to enter the merchant information, and the prompt message is "Please scan the merchant QR code and take a picture of the merchant". At the same time, there are two picture frames below the prompt message, one for displaying the merchant QR code and decoding information, and the other for taking a live picture of the merchant. When the contents of the two picture frames are ready, the system automatically enters the next step or the inspector clicks the "Next" button to enter the next step.

[0043] Figure 7 This is the interactive help information for step 2. Step 2 is to randomly select 3 leeks and put them into the sampling bag. When the inspector completes the operation, click the "Next" button to proceed to the next step.

[0044] Figure 8 It is the interactive help information of step 3. Step 3 is to print the sampling information and stick it on the sampling bag. After the inspector puts the sample into the sampling bag, he clicks the "Print Sampling Information" button, and the printing unit 13 on the sampler will print the sampling QR code and sampling information on the self-adhesive label. The inspector tears off the label and sticks it on the sampling bag, and then clicks the "Next" button to proceed to the next step.

[0045] Fig. 9 This is the interactive help information for step 4. Step 4 is to take a photo of the sampling bag. After the inspector prints the sampling information and sticks it to the sampling bag, he needs to take a photo of the sealed sample and upload it. At this time, the inspector will be prompted to "place the sampling bag on the collected object, with the QR code facing outward, and take a photo". The inspector clicks the "Photo" button, takes the corresponding photo and saves it. After the photo is taken, click "Next" to enter the next sampling task.

[0046] As mentioned earlier, "identify, judge or confirm whether the current sampling operation step is completed". For different sampling steps, the identification, judgment or confirmation method can be used to end the current sampling operation step and proceed to the next step. Among them, identification usually has intelligence, such as image recognition, human motion recognition and other methods; judgment is a simple logical judgment, such as time is up; confirmation is that the inspector actively clicks the button on the sampler screen to end the current step and start the next step. For the aforementioned steps 1, 2, 3 and 4, steps 1 and 4 are suitable for the identification method, which uses image recognition and other methods to identify whether the current operation is completed; step 2 is suitable for the confirmation method, which ends the current operation step by clicking the "Next" button; step 3 is suitable for the judgment method, which calculates the time and pastes the time, and you can proceed to the next step after the time is up.

[0047] Fig.10 This is the recognition process of step 1. First, take a photo of the merchant's QR code, save the image, and obtain the QR code information in the image. If the acquisition is successful, take a photo of the merchant's store. It is necessary to include the operator, store, and product information as much as possible. If all are included and the image quality is clear, the merchant store information is qualified, then step 1 is considered to be completed, sampling enters the next step, and the sampling operation help file is displayed synchronously.

[0048] Fig.11 This is the identification process of step 4. First, take a photo of the sampling bag and obtain the QR code information in the photo. If the QR code information is successfully obtained, the sampling object can be known; then, the image recognition method is used to determine whether the sample in the sampling bag is consistent with the sampling object, and whether the shape and size of the collected sample meet the specifications. If the recognition result is yes, step 4 is considered to be completed, the current sampling task is completed, and the next sampling task is entered.

[0049] In the current sampling process, the selection of sampling objects is specified by the system, and the inspectors sample the sampling objects on site based on their own life experience. Since the names of agricultural products vary from place to place, the sampling objects may be wrong occasionally. Since the samplers are equipped with cameras as standard, the selection of sampling objects can be achieved by taking photos. After taking the photos, the standard name of the sample is generated through the image recognition algorithm, and the test items and test methods of the sample are selected through the standard name, so as to find the corresponding sampling help file.

[0050] The testing conditions of the rapid testing room include the configuration of testing instruments, testing reagents, testing reagent inventory, tester configuration, etc. The testing conditions of each rapid testing room are different, and the inventory of testing reagents is dynamically changing. Therefore, after determining the test items, the test method can be determined according to the test conditions of the rapid testing room, so as to reasonably generate sampling tasks according to the sampling objects, test items and test methods.

[0051] Fig.12 A flowchart for generating sampling tasks based on the testing conditions of the rapid testing room. First, the testing conditions of the rapid testing room are obtained, which at least include the configuration of the testing instrument, the configuration of the testing reagents, and the inventory of the testing reagents; then, the testing method is determined based on the sampling object, the testing items, and the testing conditions of the rapid testing room; then, the sampling help prompt information is determined based on the sampling object, the testing items, and the testing method; finally, the sampling help prompt information is displayed to help the sampling personnel complete the sampling. For example, if the sampling object is leek and the detection item is pesticide residue, the pesticide residue detection item includes at least two methods: spectrophotometry and colloidal gold. If the detection instrument in the detection conditions of the rapid testing room can only detect pesticide residues, then the determined detection method is the pesticide residue spectrophotometry detection method, and the corresponding sampling method is to complete the sampling according to the help prompt information of the leek pesticide residue spectrophotometry detection method; if the detection reagent configuration and detection reagent inventory in the detection conditions of the rapid testing room only have the pesticide residue colloidal gold card, then the determined detection method is the pesticide residue colloidal gold detection method, and the corresponding sampling method is to complete the sampling according to the help prompt information of the leek pesticide residue colloidal gold card detection method.

[0052] It should be noted that the previous embodiment stores the data of the sampling task help prompt information organization chart on the network server. Since the data only depends on the attributes of the sampling object, detection item, detection method, etc., once it is built, the maintenance workload is very small. In addition, in order to reduce the amount of network transmission data, the data of the sampling task help prompt information organization chart can also be stored on the sampler.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
