Detailed Description
In order to more clearly illustrate the technical solutions of the present invention, the present invention will be briefly described below by using embodiments, and it is obvious that the following description is only one embodiment of the present invention, and for those skilled in the art, other technical solutions can be obtained according to the embodiments without inventive labor, and also fall within the disclosure of the present invention.
The food quality detection two-dimensional code traceability system is used for food with cold chain storage and transportation, such as seafood, fruits, meat, agricultural products and the like, and comprises a two-dimensional code label, a two-dimensional code scanning device, a two-dimensional code identification device, a network transmission device and a product quality cloud platform, referring to fig. 1. The two-dimensional code label is used for being arranged on the surface of food or the outer package of the food, and the two-dimensional code label can be arranged in a sticking mode.
The two-dimensional code label represents the source of the food and the current quality information through the characteristic code information product contained in the two-dimensional code label. The characteristic code comprises a plurality of number sections, and the number sections comprise food source information number sections and food quality information number sections. The corresponding information of the food source information number segment can comprise a product number, a product name, a product category, a product grade, a product origin, a product manufacturer, a product batch, a product production date and the like; the information corresponding to the food quality information number segment is that the current quality of the food is abnormal or normal. Each two-dimensional code label corresponds to information of a single food, corresponding information of the food is generated into a corresponding two-dimensional code image according to two-dimensional code codes after the food is produced, and the two-dimensional code image can be coded by using the existing two-dimensional code coding technology such as QR two-dimensional codes. And the product quality cloud platform stores the parameters of each number segment of the feature codes and the specific information corresponding to each parameter through a database.
Referring to fig. 2, the two-dimensional code label includes a base layer 10, a time temperature indicator layer 20, and a transparent film layer 30 from below. The base layer 10 may be a transparent resin layer that can be attached to the exterior package of a food. The time temperature indicator layer 20 is initially light in color and changes color to a dark color after the time above the critical temperature reaches the critical time. A polymerization type or enzyme type time temperature indicator material may be used as the time temperature indicator layer 20. The two-dimensional code image is printed on the transparent film layer 30 by ink.
The two-dimensional code label comprises a first two-dimensional code image and a second two-dimensional code image, wherein feature codes corresponding to food source information in two-dimensional code information feature codes corresponding to the first two-dimensional code image and the second two-dimensional code image are the same, and feature codes corresponding to food quality information are different. Namely, for the same food, two-dimensional code images are set, and only the characteristic codes of the food quality information in the two-dimensional code images are different. The current quality information of the food corresponding to the first two-dimensional code image is that the food quality is normal, and the current quality information of the food corresponding to the second two-dimensional code image is that the food quality is abnormal. When the first two-dimensional code image is printed, the two-dimensional code image according to the coding rule is generated according to the feature code of the first two-dimensional code image, and the dark color code element in the first two-dimensional code image is printed on the transparent film layer 30 by using black pigment. When the second two-dimensional code image is printed, the two-dimensional code image is generated according to the characteristic code, then the dark-color code element and the light-color code element in the two-dimensional code image are reversed to generate an inverse code image, and then the dark-color code element in the inverse code image is printed on the transparent film layer 30 by using light-color pigment.
In the process of cold chain storage and transportation of food with the two-dimensional code label, if the temperature of the food is normal, the color of the time temperature indicator layer 20 in the two-dimensional code label is unchanged, so that the dark-color code elements in the first two-dimensional code image and the light-color background of the time temperature indicator layer 20 form enough reflectivity difference, and the first two-dimensional code image can be identified; whereas the light-colored symbols in the second two-dimensional code image are not recognizable as an image against the light-colored background of the time-temperature indicator layer 20. If the food is abnormally stored after the time exceeding the critical temperature reaches the critical time in the cold chain storage and transportation process, the color of the time temperature indicator layer 20 becomes dark, so that the difference between the reflectivity of the dark-color code element in the first two-dimensional code image and the reflectivity of the dark-color background of the time temperature indicator layer 20 is too small to be recognized, and the two-dimensional code image formed by the light-color code element in the second two-dimensional code image and the dark-color background of the time temperature indicator layer 20 can be recognized.
When a consumer purchases or uses food, the first two-dimensional code image and the second two-dimensional code image in the two-dimensional code label corresponding to the food are acquired through two-dimensional code scanning equipment such as a camera. Then, the first two-dimensional code image and the second two-dimensional code image are recognized by the two-dimensional code recognition device, wherein only one two-dimensional code image can be recognized. Food feature code information identified by the two-dimension code identification equipment is transmitted to the product quality cloud platform through the network transmission equipment, and the product quality cloud platform searches food source information and food quality information corresponding to the food feature code parameters in the database. And after the product quality cloud platform finishes the query, returning the query result to the network transmission equipment. And after receiving the food information obtained by the product quality cloud platform inquiry, the network transmission equipment displays the food information through a human-computer interaction interface. In the above embodiment, the two-dimensional code scanning device, the two-dimensional code recognition device, and the network transmission device may be integrated in the same device, for example, a mobile phone or a mobile intelligent terminal, and the above operations may be implemented by an APP of the mobile phone or the mobile intelligent terminal.
The food quality detection two-dimensional code traceability system can not only provide traceability information in the food production and transportation process, but also provide dynamic information of the real-time state of food, thereby effectively controlling each process of a food supply chain and ensuring the safety and quality of the food.
