Precise information acquisition and tracing system and tracing method based on DM (Data Matrix) two-dimension code grain tracing particles

Abstract

The invention discloses a precise information acquisition and tracing system and a tracing method based on DM (Data Matrix) two-dimension code grain tracing particle, which take the food-grade DM two-dimension code grain tracing particles as a carrier of a grain producing area information identifier, and develop automatic acquisition and transmission based on information of each link for ARM (Advanced RISC Machines) grain tracing as a rapid full-range grain tracing system with low cost to provide an effective manner for guaranteeing the grain quality and the safety production. The tracing system comprises an environment information acquisition node, a wireless sensor network, a mobile terminal provided with a wireless communication module, a GPRS (General Packet Radio Service) locating module and a DM two-dimension code image capture module, and an upper computer grain information tracing platform. The upper computer grain information tracing platform recognizes and decodes a plurality of DM two-dimension code areas in received grain images to obtain grain production mark information, stores the grain production mark information, the grain environment information and the position information together, and publishes on the internet. A user can search related grain information through a mobile phone client.

Description

technical field [0001] The present invention relates to grain safety traceability technology, wireless network communication technology, sensor technology and DM two-dimensional code technology, specifically an accurate information collection traceability system and traceability method based on DM two-dimensional code grain traceability particles. Background technique [0002] In recent years, food safety problems are common, and food safety has become a global problem. People's worries about food shortages have been replaced by food safety fears. Countries around the world have attached great importance to food safety issues. The agricultural product quality traceability system uses the agricultural product information traceability technology to track the information of the whole process. In each link of the supply chain, the origin and production environment of agricultural products are tracked and traced. Once an agricultural product quality safety incident occurs, the agr...

[0003] However, in grain production traceability, since grain is composed of small units, the traceability process in grain production is different from that of other agricultural products, which can be accurately traced to the source through unique identification information. Grain production needs to be sourced from multiple sources according to different grades or different uses Therefore, it is difficult to determine the precise origin information of a batch of grain due to the mixed distribution and distribution of grains from different origins.

At the same time, the existing grain traceability system is difficult to achieve the transparency of the whole process of traceability of grain production
