摘　　要：以自主研发的条码溯源电子秤为信息采集基础、以交易信息数据库为管理核心、以手机扫描二维条码为追溯手段,构建了社区菜店交易管理与追溯系统框架。条码溯源电子秤在集成相关模块的基础上,实现了产品称量、身份验证、标签打印和数据上传等功能。在突破电子秤数据传输与解析技术、改进包含多条信息的手机扫描二维条码追溯识别技术的基础上,实现了社区菜店交易管理与追溯系统。通过搭建模拟环境,对连接多台电子秤的数据传输稳定性、手机扫描二维条码追溯进行了测试。结果表明,无论是实时传输方式还是集中传输方式,其传输成功率均在99%以上;随着标签中产品数量的增加,不同像素的手机识别速度和识别成功率均存在不同程度的下降趋势,其中800万像素的手机在识别速度上具有明显优势。A framework for community vegetable shop to manage the transaction information and trace products was created. In this system, information acquisition was carried out based on barcode traceability electronic scale. The management core of the system was the database of transaction information. A mobile was used as the barcode scanner for tracing. The barcode traceability electronic scale integrated related models to achieve many functions, such as weighting, authentication, label printing and data uploading. To build the transaction management and traceability system of community vegetable shops, the electronic scale＇ s data transaction and analysis were carried out, and the mobile＇ s recognition technology of 2-D code which contained multiple pieces of information was improved. By building the simulation environment, the data transmission stability of multiple electronic scales, which were connected with the computer at the same time and the traceability function by scanning 2-D code with a mobile, was tested. The results show that the transmission success rates are above 99% by either real-time transmission or centralized transmission. With the increase of products number in one label, there is a decline in both recognition speed and recognition success rate of different pixel mobile phones. Meanwhile, the mobile phone with 8 million pixels has obvious advantages in recognition speed.
