CAN总线嵌入式系统在食品追溯系统中的应用

Application of CAN Bus Embedded-system in Food Traceability System

在分析EAN/UCC系统的基础上,介绍了一种利用CAN总线技术和嵌入式控制技术实现猪肉屠宰与分割环节追溯系统的方法。该系统通过位于各加工节点的嵌入式微控制器实时控制读取和打印符合EAN/UCC规范的条码标签,并利用CAN总线与上位机进行信息交换来保证可追溯性。详细地介绍了基于CAN总线的屠宰加工现场追溯系统的结构以及上位机和各加工节点的软、硬件设计方法。

Based on an analysis of the EAN/UCC system, the paper introduces an realization of the pork traceability system in the process of slaughter and segmentation, which combines CAN bus technology and embedded control technology, and then gives a detailed description to the structure of the system.
