[0002] Currently, two food safety detection cards are configured. One is a food detection card for sampling and detection, and the other is a corresponding standard card for comparing the analysis results of the food detection card. In specific applications, the food detection card and the standard card need to be inserted into the detection device at the same time. The detection device reads the information in the food detection card and the standard card respectively, and makes a comparison to finally complete the detection. The final detection result is also stored in the detection device.

[0044] Embodiment 1

[0045] According to an embodiment of the present invention, there is provided an embodiment of a method for transmitting food safety detection information without a standard card. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0046] In Embodiment 1 herein, there is provided a method for transmitting food safety detection information without a standard card, which can be used in an electronic device, such as a computer. It should be noted that this method is applied to the scenario of setting an identifier on a food detection card. It can be understood that this identifier is a unique identifier, such as a QR code, a barcode, and a chip, etc.

[0047] Please refer to Figure 1 , Figure 1 which shows an implementation flowchart of a method for transmitting food safety detection information without a standard card provided by Embodiment 1 of the present invention, specifically including steps S01 to S03.

[0048] Step S01, establish a mapping relationship between the identifier of the food detection card and the detection standard of the corresponding food type.

[0049] Among them, the unique identifier on the food detection card is corresponded to different types of foods. Exemplarily, when the food detection device scans identifier a, according to the mapping relationship, it is determined as food x; when the food detection device scans identifier b, according to the mapping relationship, it is determined as food y.

[0050] Step S02, read the identifier of the food detection card through the food detection device, and determine the detection standard of the corresponding food type according to the identifier of the food detection card and the mapping relationship.

[0051] It can be understood that different foods have their corresponding food safety detection standards. The food safety detection standards are converted into index values and stored in the system. When it is determined to conduct a food safety detection on a certain specific food, the corresponding index values are called for comparison.

[0052] Step S03: Compare the analysis result obtained by analyzing with the food test card with the detection standard of the corresponding food type, and transmit the comparison result to the application terminal communicatively connected to the food detection device.

[0053] Specifically, analyze the test substance collected on the food test card in the food detection device to obtain the analysis result, compare the analysis result with the corresponding index value, and finally send the comparison result to the user terminal by means of wireless transmission (such as Wifi, Bluetooth, etc.).

[0054] In this embodiment, when the comparison result shows qualified, obtain the historical comparison results stored in the application terminal, compare the current comparison result with the historical comparison results, and determine the origin of the currently detected food. It should be noted that the pesticide spraying situation of food is related to the region, specifically related to climate factors, soil conditions, and types of planted crops, etc. For example, fertile soil can make crops grow strong and have relatively strong self-resistance, which may relatively reduce the amount of pesticide used. While crops grown in poor soil are vulnerable to pest and disease attacks and require more pesticides to ensure yield and quality.

[0055] Specifically, determine the corresponding detection indexes according to the food type, and generate the corresponding standard polygon according to the detection indexes. It can be understood that if there are five indexes, a pentagon is generated, and if there are six indexes, a hexagon is generated;

[0056] Perform clustering analysis on each detected value in the historical analysis results of the same origin and the same food type to obtain the clustering results of each detected value. Among them, the K-means clustering algorithm can be used for clustering analysis. By clustering, find the data characteristics of each origin and each food type;

[0057] Present the clustering results of each detected value in the form of a polygon according to the standard polygon to obtain the first polygon. Among them, on the basis of the standard polygon, generate an irregular polygon according to the clustering results of each detected value;

[0058] Present each detected value in the current comparison result in the form of a polygon according to the standard polygon to obtain the second polygon;

[0059] Compare the second polygon with the first polygon to determine the target polygon that matches the second polygon. Specifically, obtain the area of the second polygon and the areas of each first polygon, subtract the area of each first polygon from the area of the second polygon respectively, and determine the first polygon with the smallest area difference to initially screen out the polygon that is closest;

[0060] Judge whether the first polygon with the smallest area difference is unique;

[0061] If the first polygon with the smallest area difference is not unique, calculate the distances between the vertices of the first polygon with the smallest area difference and the corresponding vertices of the second polygon respectively, and determine the corresponding weights according to the distances. It should be noted that when calculating the distances between the vertices, the first polygon and the second polygon can be mapped to the same plane rectangular coordinate system, and the distances are calculated through the corresponding coordinate points of the vertices. In addition, according to the importance of different indicators, determine the corresponding first weight, and then determine the corresponding second weight according to the distances between the vertices. Among them, each distance range corresponds to a weight value, and the weight value is determined according to the distance range in which the distance between the vertices falls. It can be understood that the greater the importance of the indicator, the greater the first weight, and the smaller the distance between the vertices, the greater the second weight;

[0062] Calculate the score according to the distance and the corresponding weight, and determine the first polygon with the highest score as the target polygon. Among them, the calculation formula of the score is:

[0063] ;

[0064] Among them, F represents the score, α i represents the first weight of the i-th indicator, β i represents the second weight of the i-th indicator, Z i represents the distance of the i-th indicator;

[0065] Determine the origin of the currently detected food according to the origin of the detected food corresponding to the target polygon, which can prevent the problem of misusing well-known origins.

[0066] In this embodiment, in the step of transmitting the comparison result to the application terminal communicatively connected to the food detection device, encrypt the data transmission of the comparison result to improve the security of data transmission. Specifically, randomly generate a string with a preset number of characters, and generate a QR code with rounded corners according to the string, that is, a QR code composed of black circles. It should be noted that this QR code can also be randomly deformed according to the identification QR code of the food detection card in accordance with the encoding rules;

[0067] Map the second polygon and the clock dial with a second hand to the QR code, and control the second polygon and the clock dial with a second hand to be scaled proportionally until they are tangent to the edge of the QR code;

[0068] When generating the clock dial with a second hand, control the second hand to move a preset number of times according to the current time, and respectively obtain the coordinates and the number of intersections between the second hand and the rounded corner patterns inside the second polygon scaled proportionally in the QR code. Among them, the origin of coordinates can be the lower left corner of the QR code, and each black circle represents the position of a coordinate point;

[0069] Insert the coordinates into the string, and perform a hash operation according to the quantity to obtain a hash value for encryption. It should be noted that according to the preset number of times the second hand moves, the corresponding coordinates are randomly inserted into the string in batches. Among them, after inserting the corresponding coordinates into the string for each batch, a corresponding number of hash operations are performed according to the corresponding quantity. Exemplarily, at the current moment, the second hand is at the 12 o'clock direction, that is, the zero-second position. The second hand moves twice, to the one-second position and the two-second position respectively. Determine the coordinates and quantity where the second hand intersects the rounded corner pattern at the one-second position. Randomly insert the intersecting coordinates into the string in the order from near to far, where the far refers to the extension direction of the second hand, and perform a corresponding number of hash operations according to the corresponding quantity. For example, if the quantity is five, then perform five hash operations to obtain the first operation result. Among them, randomly inserting the coordinates into the string means inserting the numbers in the coordinates into the string. Further, determine the coordinates and quantity where the second hand intersects the rounded corner pattern at the two-second position. Randomly insert the intersecting coordinates at this time into the first operation result, and perform a corresponding number of hash operations according to the corresponding quantity to obtain the final hash value.

[0070] In some other embodiments of the present invention, the movement of the second hand can be controlled for a preset number of times, with a preset interval for each movement, or the position of the second hand can be controlled randomly.

[0071] In summary, for the food safety detection information transmission method without a standard card in the above embodiments of the present invention, the method establishes a mapping relationship between the identifier of the food detection card and the detection standard of the corresponding food type; reads the identifier of the food detection card through the food detection device, and determines the detection standard of the corresponding food type according to the identifier of the food detection card and the mapping relationship; compares the analysis result obtained by analyzing the food detection card with the detection standard of the corresponding food type, and transmits the comparison result to the application terminal communicatively connected to the food detection device. Specifically, since the standard card is cancelled and an identifier is set on the food detection card, the detection operation is effectively simplified. At the same time, the detection result is transmitted to the application terminal communicatively connected to the food detection device, improving the convenience of data transmission.
