| 中文摘要: |
| 目的 针对目前超市高峰时段结算排队拥堵、价签不符修正耗时的弊端，设计一款辅助顾客购物的自助式结算系统， 以提高购物结算效率。 方法 采用摄像头输入商品条码进行识别 ， 以获得对应商品的价格、库存及质量等信息。 结合压力传感器获取商品的质量信息， 对比与扫描商品质量的一致性， 不一致则提示“码重”出错。 结果 选用 低成本传感器， 对超市内质量大于 15 g的商品， 采用将条码扫描质量与压力传感器获取质量进行一致性匹配校验的方法， 可以进一步提高确认购买商品类别的有效性和准确性。 结论 系统具有友好的交互界面， 便于顾客及时核对商品的单价与总价， 在出口收款台无需进行第 2次扫码， 直接结算可节省时间与人力成本； 系统采用 LabVIEW编程实现与超市中央数据库的关联，为数据更新的零时间等待提供了良好的技术支撑。 |

| Objective To solve the problem of the peak hours queuing congestion and the long correct time when the price was not consistent with the tag which were prevalent in the supermarket checkout system, a self-service shopping settlement system was provided in this paper. Methods The commodity barcode was recognized after being input by camera though scanning to obtain the corresponding information such as price, inventory and weight. In combination, the pressure sensor was used to obtain weight information which was compared to the scanned weight of the goods to test consistency and the "wrong weight" would be indicated if inconsistency was revealed. Results Using the low cost pressure sensor for the goods with weight of more than 15 g in the supermarket, the method of matching the bar code with the weight could further improve the effectiveness and accuracy of the commodity information. Conclusion The user-friendly interactive interface was convenient for customer to check the unit price and total value of the goods in a timely manner. Without scanning the codes again at the cashier's desk, the payment could be accomplished in a manner that saved time and manpower cost. The system could conveniently and flexibly implement the connection with supermarket central database by LabVIEW, which provides a good technical support for no waiting of data update. |
