Two-dimensional code vegetable security traceability marking and inquiring system based on space-time information

Abstract

The invention discloses a two-dimensional code vegetable security traceability marking and inquiring system based on space-time information. The two-dimensional code vegetable security traceability marking and inquiring system comprises a central controller module, a positioning module, a screen display module, a remote communication module, a signal conversion module, a two-dimensional code printing module, a lithium battery module and a central database, wherein the positioning module, the screen display module, the remote communication module and the signal conversion module are all connected with the central controller module; the two-dimensional code printing module is connected with the signal conversion module; the remote communication module is in communication with the central database through a wireless signal; the lithium battery module is used for supplying power to the whole system. According to the two-dimensional code vegetable security traceability marking and inquiring system based on the space-time information, disclosed by the invention, the uniqueness and the authenticity of a two-dimensional code are ensured according to time information and space information of the generated two-dimensional code, accurate tracking on a complete process of production, processing, storage and selling of vegetables can be realized, and the vegetable quality safety supervision ability can be increased; the right of consumers to know the quality information of vegetable products is guaranteed through vegetable quality security traceability.

Description

technical field [0001] The invention belongs to the technical field of agricultural product quality and safety traceability, and in particular relates to a two-dimensional code agricultural product information identification and query system based on spatio-temporal information. Background technique [0002] The safety of agricultural products is related to the health and life safety of farmers. Although the government has strengthened the supervision of food, fake and inferior products are still rampant in the market. Therefore, it is very important to improve the transparency of the food production process. The traceability of food can improve the quality and safety supervision level of agricultural products, ensure product quality, and truly protect the legitimate rights and interests of consumers. [0003] The currently applied vegetable quality and safety traceability identification system is not unique and is easy to imitate, which greatly restricts the promotion and a...
