【摘要】 随着人们生活节奏的加快,传统的电子称称重结账在客流高峰时段造成的排队等待问题日益凸显,因此亟需一种快速、便捷的称重结账系统。因此本文设计了一种新型的称重系统,多个称重节点可同时称重,通过蓝牙4.0技术搭建星型拓扑结构的无线传感器网络,将称重数据汇聚至蓝牙终端(可采用智能手机、平板或电脑),并设计了客户端程序,手动输入单价,将称重数据、单价、总价等数据进行显示、保存。本系统具有速度快、功耗低、成本低、操作简便等优点。更多还原

【Abstract】 Traditional electronic balance system wastes customers a lot of time when weighting checkout at peak hours,therefore a fast and convenient weighing checkout system is needed. This paper designs a new kind of weighing system,a plurality of weighing nodes can weigh at the same time,and with a wireless sensor network of star topology via Bluetooth 4.0 technology,the weighing data will aggregate to the Bluetooth terminal( by intelligent mobile phone,tablet or computer),through the client terminal,manual input unit,the weighing data,the unit price and the total price can be automatically displayed and stored. This system has the advantages of high speed,low power consumption,low cost,and easy operation.更多还原
