基于树莓派和LabVIEW的电子秤设计

Design of Electronic Scale based on Raspberry Pie and LabVIEW

提出了一种基于树莓派和LabVIEW的电子秤设计,包括称重硬件和LabVIEW显示两部分。称重硬件包括树莓派控制器、电阻应变式传感器、HX711模数转换芯片等模块;LabVIEW可显示物体重量、输入物体单价、显示总价及测量时间等信息,同时将信息记录表单,本系统具有操作简单、测量精度高、可移动性强、实时性好等优点。

An electronic scale design based on raspberry pie and LabVIEW is presented,including two parts:weighing hardware and LabVIEW display.The weighing hardware includes the raspberry pie controller,the resistance strain sensor,the A/D conversion chip HX711 and other modules.The LabVIEW can display the information of the weight of the object,the unit price of the object,the total price,the time and date of the display,and the form of the information.The system has a simple operation,high precision,and strong mobility,good real-time and so on.
