一种多功能智能电子秤的设计与制作

Design and Manufacture of Multi-function Iintelligent Electronic Scale

我们采用单片机与传感器,设计了一种多功能智能电子秤。该电子称的称重系统主要由电阻应变计、弹性器件、电阻和外壳等组成。传感器负责数据的采集,HX711进行数据的放大与A/D转换,LCD1602显示被称物的重量信息。按所作设计,制作出样机,并进行了测试。结果表明:该电子秤称重量程为5kg,可实现称重、物品价格设置和总价计算等功能。

This design is a kind of multi-functional intelligent electronic scale using single chip microcomputer and sensor technology.The weighing system used for data collection,the amplification of data and A/D conversion with HX711 and showing the weight of the items with LCD1602,is mainly composed of resistance strain gauge,elastic device,resistance,the shell and so on.The modules and design methods of the electronic scale are introduced in detail in this paper,and the prototype assembly and testing are carried out.The test results show that the weighing range of the system is 5 kg,which can realize the functions of weighing,price setting and total price calculation.
