物流和仓储是农产品供应链的主要加工环节。由于两次处理之间信息脱节，难以连续追踪。智能输送带通过二维码扫描和信息记录，为仓储和物流关联提供了有效的方法。提高二维码在运动状态下的可读性是该皮带实现连续链追溯的核心。本文设计了一种智能输送带，包括自动输送单元、条码扫描单元、故障排除单元和控制显示单元。选取影响二维码可读性的四个因素，并确定其取值范围，即读取距离、条码尺寸、编码字符和皮带移动速度。在此带的基础上，采用响应面法（RSM）设计了四因子五水平的中央复合刻录（CCI）实验，以获得最佳读取参数。结果表明，读取距离、传送带移动速度以及读取距离与条码尺寸的交互作用等主要因素对QR码可读性影响显着。在读取距离141.45 mm、条码尺寸34.58 mm、编码字符100字节、皮带移动速度2.98 m/min的优化条件下，二维码可读性平均值为95%。经过参数优化后，智能输送带应用于某苹果营销企业。结果表明，可以实现仓储物流的连续追溯，且可扩展广度、加深深度、提高精度。
Logistics and storage is the main processing for agro-food supply chain. Because of disconnection information between the two processing, it is difficult to trace continuously. An intelligent conveyer belt provides an effective method to associate storage and logistics by QR code scanning and information recording. Improving the QR code readability in movement state is the core of implementing continuous chain traceability with this belt. In this paper, a intelligent conveyer belt including automatic conveyer unit, barcode scanning unit, fault remove unit and control display unit was designed. Four factors affected QR readability were selected and the value range was confirmed, which was reading distance, code size, coded characters and belt moving speed. Based on the belt, an Central Composite Inscribed (CCI) experiment of four factors with five levels was designed using Response Surface Methodology (RSM) to obtain the optimal reading parameters. The result shows that the main factors of reading distance, belt moving speed and the interaction between reading distance and code size have the significant effect on QR code readability. Under the optimization condition of 141.45 mm reading distance, 34.58 mm code size, 100 bytes coded characters and 2.98 m/min belt moving speed, the average value of QR code readability was 95%. With the optimization parameters, the intelligent conveyer belt was used in an apple marketing enterprise. The result shows that the continuous traceability between storage and logistic can be implemented with the extended breadth, deepened depth and improved precision.
