| Blueberry is a small berry tree that emerged in the United States in the early 20 th century.Blueberry is a kind of widely used agricultural product because of its rich nutritional value and high medicinal value.The traceability system of blueberry products is a convenient means to control the quality and safety of blueberry agricultural products.In this paper,the concept of traceability system of blueberry products is expounded,and one of the key technologies of traceability system of blueberry products is analyzed in depth.The project is based on the Internet of Things technology,aiming at improving the quality of blueberry products and establishing and improving a set of quality monitoring and traceability system for blueberry production data in the stages of planting,processing and logistics.Sensors are used to transmit environmental information such as soil temperature and humidity,air temperature and humidity,and light level to the platform.Observing and recording the resource allocation and important information in the process of blueberry planting.In the process of processing,taking the production of blueberry products as an example,using video surveillance and RFID technology to record the information before and after blueberry growth and sale,generating two-dimensional code information.The two-dimensional code data includes all kinds of information of blueberry,including unique identification information such as variety,picking time and origin.If consumers can purchase the blueberry juice for one-time certification,they can inquire all the information traceable to the blueberry juice,and then realize the visual inquiry of blueberry product quality in the whole process to ensure that the blueberry products purchased by consumers are safe and secure.In the process of transportation,detailed tracking and feedback can be given to the transportation environment,so as to achieve early warning effect and ensure the controllability of product quality. |
