多功能智能电子秤的设计与实现

Design and Implementation of Multifunctional Intelligent Electronic Scale

以STC89C52RC单片机作为微控制器,以电阻式压力传感器为数据采集模块,HX711数模转换器为信号处理模块,LCD1602为显示模块,设计了一种智能自动称量电子秤.详细介绍了系统的各组成模块、设计方法和功能实现过程,并对系统功能进行了分析和评价.结果表明:设计的系统可实现物重测量、物价设置、总价计算等功能.

In this paper, we design an intelligent automatic weighing electronic scale based on STC89C52RC MCU for micro-controller, using resistive pressure sensor as the data acquisition module, adopting HX711 converter for signal processing module, LCD1602 displayed module. We introduce the modules, design methods and function realization process of the system in details, and analyze and evaluate the function of system. The results show that the system designed in article can realize some functions such as weight measurement, price setting, and the total price calculation.
