Abstract
In response to the national call of “food safety”, this paper introduces edge computing and block chain technology to design the agricultural super docking traceability system for fresh agricultural products. The system employs two-dimensional code, camera, temperature and humidity sensors and other terminal equipment to collect real-time data, including the detection data of fresh agricultural products, the information of processing and packaging fresh agricultural products, the status of fresh agricultural products during transportation. Edge computing technology is used to process edge information, alleviate the network transmission congestion and network delay of the traceability system. Blockchain technology is used to implement the safe storage tamper-resistant of data. Our research also carried out a traceability system construction of fresh agricultural products for a supermarket in Yucheng city.
