Design and Implementation of Food Security Traceability System based on Internet of Things Technology

The production, circulation and consumption of grain have a direct bearing on the vital interests of the people and the state. Since ancient times, food security has been the foundation of economic development, social stability and national self-reliance. Therefore, food security and food security must be effectively guaranteed in order to promote the sustainable development of the national economy. According to the introduction of the industry, in China, there are still threats to food security factors. First of all, due to the low comparative benefit of grain planting, farmers are less and less motivated to grow grain, which directly limits the improvement of China’s grain supply capacity. This paper mainly studies the design and implementation of food security traceability system based on Internet of things technology. This paper combines Internet of things technology to design food security traceability system for food security problems. The “household settlement card system” based on RFID technology enables farmers to swipe their credit CARDS to sell grain by issuing them to grain farmers free of charge. Farmers sell grain, subsidies management more convenient. Grain sales and subsidies can be directly deposited into the bank account associated with the settlement card of farmers, so as to avoid farmers carrying large amounts of cash and facilitate farmers.
