摘　　要：基于物联网的智能超市结算系统由上位机和下位机组成,两者进行点对多点通信。系统以PIC16 F887单片机为主控制器,利用扫描枪PS/2接口对商品条形码信息进行采集,由ADS7843触摸显示屏对采集信息直观显示,然后通过触摸指令将商品信息通过NRF905无线传输模块发至上位机(收银处),现实实时的记账和结账功能。只要将下位机配于购物车或购物篮,即可大大节省消费者着排队结算的时间。The intelligent design based on Intemet of things the supermarket settlement system, the system is composed, the position of the upper and lowers two points to multipoint communication. System is given priority to with PIC16F887 single-chip microcomputer controller, using scanning gun PS / 2 interface of commodity barcodes information collection, analysis and processing of the controller, the visual display of the touch screen to collect information by ADS7843, then through touch commands will commodity information through NRF905 wireless transmission module is sent first place machine （checkout）, real-time billing and invoicing. As long as the machine match in the shopping cart or basket, can greatly save queuing and settlement time.
