DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] Embodiment 1 According to an embodiment of the present invention, an embodiment of a method for transmitting food safety detection information without a standard card is provided. 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 a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0021] In the first embodiment of the present invention, a method for transmitting food safety detection information without a standard card is provided, which can be used in electronic devices, such as computers. It should be noted that the method is applied to the scenario of setting an identification on a food detection card. It can be understood that the identification is a unique identification, such as a QR code, a barcode, and a chip.

[0022] See also Figure 1 , Figure 1 A flowchart of a method for transmitting food safety detection information without a standard card provided in the first embodiment of the present invention is shown, which specifically includes steps S01 to S03.

[0023] Step S01, establishing a mapping relationship between the identification of a food testing card and the testing standard of the corresponding food type.

[0024] Among them, the unique identifier on the food inspection card corresponds to different types of food. For example, when the food inspection equipment scans the a identifier, it is determined to be x food according to the mapping relationship; when the food inspection equipment scans the b identifier, it is determined to be y food according to the mapping relationship.

[0025] Step S02, reading the identification of the food detection card by the food detection device, and determining the detection standard of the corresponding food type according to the identification of the food detection card and the mapping relationship.

[0026] It is understandable that different foods have their corresponding food safety testing standards, which are converted into index values ​​and stored in the system. When it is determined to conduct food safety testing on a specific food, the corresponding index value is called for comparison.

[0027] Step S03, comparing the analysis result obtained by analyzing the food detection card with the detection standard of the corresponding food type, and transmitting the comparison result to the application end that is communicatively connected to the food detection device.

[0028] Specifically, the objects to be tested collected on the food testing card are analyzed in the food testing equipment to obtain the analysis results, and the analysis results are compared with the corresponding index values. Finally, the comparison results are sent to the user terminal via wireless transmission (such as Wifi, Bluetooth, etc.).

[0029] In this embodiment, when the comparison result shows qualified, the historical comparison result stored in the application end is obtained, and the current comparison result is compared with the historical comparison result to determine the origin of the currently tested food. It should be noted that the pesticide spraying of food is related to the region, specifically to climate factors, soil conditions, and types of crops planted. For example, fertile soil can make crops grow strong and have strong resistance, which may relatively reduce the use of pesticides. Crops grown in poor soil are susceptible to pests and diseases, and more pesticides are needed to ensure yield and quality.

[0030] Specifically, the corresponding detection index is determined according to the type of food, and the corresponding standard polygon is generated according to the detection index. It can be understood that if there are five indicators, a pentagon is generated, and if there are six indicators, a hexagon is generated; Perform cluster analysis on each test value in the historical analysis results of the same origin and the same food type to obtain the cluster results of each test value. K-means clustering algorithm can be used for cluster analysis to find the data characteristics of each origin and each food type through clustering. According to the standard polygon, the clustering results of each detection value are presented in a polygonal manner to obtain a first polygon, wherein, on the basis of the standard polygon, an irregular polygon is generated according to the clustering results of each detection value; According to the standard polygon, each detection value in the current comparison result is presented in a polygonal manner to obtain a second polygon; The second polygon is compared with the first polygon to determine a target polygon that matches the second polygon. Specifically, the area of ​​the second polygon and the area of ​​each first polygon are obtained, and the area of ​​each first polygon is subtracted from the area of ​​the second polygon to determine the first polygon with the smallest area difference, so as to preliminarily select the closest polygon. Determine whether the first polygon with the smallest area difference is unique; If it is determined that the first polygon with the smallest area difference is not unique, the distance between each vertex of the first polygon with the smallest area difference and the corresponding vertex of the second polygon is calculated respectively, and the corresponding weight is determined according to the distance. It should be noted that when calculating the distance of the vertices, the first polygon and the second polygon can be mapped to the same plane rectangular coordinate system, and the distance is calculated through the coordinate points corresponding to the vertices. In addition, according to the importance of different indicators, the corresponding first weight is determined, and then according to the distance of the vertices, the corresponding second weight is determined, wherein each distance range corresponds to a weight value, and the weight value is determined according to the distance range into which the distance of the vertex falls. It can be understood that the greater the importance of the indicator, the greater the first weight, and the smaller the distance of the vertices, the greater the second weight; According to the distance and the corresponding weight, the score is calculated, and the first polygon with the highest score is determined as the target polygon, where the score calculation formula is: ; 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; The origin of the current tested food can be determined based on the origin of the tested food corresponding to the target polygon, thereby preventing the problem of impersonating a well-known origin.

[0031] In this embodiment, in the step of transmitting the comparison result to the application end that is in communication connection with the food testing device, the data transmission of the comparison result is encrypted to improve the security of data transmission. Specifically, a character string of a preset number of characters is randomly generated, and a rounded QR code is generated according to the character string, that is, a QR code composed of black circles. It should be noted that the QR code can also be obtained by randomly deforming the identification QR code of the food testing card in accordance with the coding rules; Mapping the second polygon and the clock dial with the second hand onto the QR code, and controlling the second polygon and the clock dial with the second hand to scale in equal proportion until they are tangent to the edge of the QR code; While generating a clock dial with a second hand, control the second hand to move a preset number of times according to the current time, and obtain the coordinates and number of intersections between the second hand and the rounded pattern in the second polygon after the QR code is scaled in the same proportion, where the coordinate origin can be the lower left corner of the QR code, and each black circle represents a coordinate point position; Insert the coordinates into the string, and perform a hash operation according to the number 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, wherein each batch of corresponding coordinates are inserted into the string, and then a hash operation is performed a corresponding number of times according to the corresponding number. Exemplarily, at the current moment, the second hand is at the twelve o'clock direction, that is, the zero second position, and the second hand moves twice, one second position and two second position respectively. The coordinates and number of intersections between the second hand and the rounded pattern at the one second position are determined, and the coordinates intersecting at this time are randomly inserted into the string in order from near to far, wherein the far distance refers to the extension direction of the second hand, and a hash operation is performed a corresponding number of times according to the corresponding number. For example, if the number is five, five hash operations are performed to obtain a first operation result, wherein randomly inserting the coordinates into the string refers to inserting the numbers in the coordinates into the string. Further, the coordinates and number of intersections between the second hand and the rounded pattern at the two second position are determined, and the coordinates intersecting at this time are randomly inserted into the first operation result, and a hash operation is performed a corresponding number of times according to the corresponding number to obtain a final hash value.

[0032] In some other embodiments of the present invention, the second hand can be controlled to move a preset number of times, with a preset interval for each movement, or the position of the second hand can be controlled to be random.

[0033] In summary, the method for transmitting food safety detection information without a standard card in the above-mentioned embodiments of the present invention establishes a mapping relationship between the identification of the food detection card and the detection standard of the corresponding food type; reads the identification of the food detection card by a food detection device, and determines the detection standard of the corresponding food type according to the identification 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 end that is communicatively connected to the food detection device. Specifically, since the standard card is cancelled and the identification is set on the food detection card, the detection operation is effectively simplified, and the detection result is transmitted to the application end that is communicatively connected to the food detection device, thereby improving the convenience of data transmission.
