基于物联网技术的智能购物车设计

为了有效解决超市中出现的排队等待结账难、手推购物车不方便、寻找目标商品难等问题，设计了基于超高频率射频识别技术和超宽带室内定位技术，并辅以手机网页和云端大数据库完成的智能购物车系统，在车载自助结账系统、购物车智能跟随系统、云端大数据库自主导航系统3个方面做了突破。首先，顾客进入到超市之后，只需要扫码领取一辆智能购物车，然后便可以在手机上完成对购物车的操控，同时手机的网页也会实时显示顾客的购物信息，最后，顾客不再需要排队等待结账，只需要在手机网页上完成支付即可。设计结果表明，智能购物车可以有效解决超市中存在的问题，实现购物过程的全自助。设计方案可应用于智能超市，取代传统超市的人工结账和导购，可以有效缓解超市人员的工作压力。

Design of intelligent shopping cart based on internet of things technology

In order to effectively solve the problems in supermarkets,such as difficulty in waiting in line for checkout,inconvenience in pushing shopping cart and difficulty in finding target products,an intelligent shopping cart system based on ultra-high frequency radio frequency identification technology and ultra-wide band indoor positioning technology was designed,and was completed with cell phone web pages and a large cloud database.Breakthroughs have been made in three aspects:vehicle self-service checkout system,shopping cart intelligent following system,and cloud-based large database autonomous navigation system.First of all,after entering the supermarket,customers only need to scan the code to receive a smart shopping cart,and then they can finish controlling the shopping cart on the cell phone,and the cell phone webpage will also display the shopping information of customers in real time.Finally,customers no longer need to wait in line for checkout,but only need to finish the payment on the cell phone web page.The design results show that the intelligent shopping cart can effectively solve the problems existing in the supermarket and realize the full self-service in the shopping process.The device can be applied to the intelligent supermarket,replacing the manual checkout and shopping guide of the traditional supermarket,and relieving the pressure of supermarket personnel.
