| 摘 要: 针对农产品易出现产地造假等质量监管方面的不足，将物联网和区块链结合起来，建立基于“区块链+物联网”的农产品溯源系统。在生产过程中，通过温湿度传感器、光照传感器以及GPS模块等采集信息，通过ZigBee技术进行节点布置。在运输环节，通过二维码技术对每件产品赋予唯一的身份信息，通过GPS和摄像头来监控位置变化，收集到的信息通过区块链技术进行数据存储。当消费者购入产品时，只需扫描产品上的二维码，就可以对产品进行全方位的追根溯源。结果表明，该方案覆盖农产品的全生命周期，优化了农产品溯源信息的存储与查询，有一定的实用性。 |

| Abstract: Aiming at quality supervision deficiencies of agricultural products like fake origins, this paper proposes to establish a traceability system for agricultural products based on "Blockchain + Internet of Things" by integrating the Internet of Things and blockchain. In production process, product information is collected through temperature and humidity sensors, light sensors, and GPS modules, etc., and collection nodes are distributed by ZigBee technology. In transportation process, each product is given unique identity information through QR (Quick Response) code technology, and its location changes are monitored through GPS and cameras. The collected information is stored through blockchain technology. When consumers purchase a product, they just scan the QR code and all-around information about the product can be traced. Results show that this practical solution covers entire life cycle of agricultural products, and optimizes storage and query of agricultural product traceability information. |
