摘要
电子称是日常生活中常用的测量仪器之一。系统采用电阻应变片式压力传感器将力转换为电信号,单片机STC89C51作为控制核心。电路硬件部分包括传感器模块、控制模块、A/D转换模块、按键模块、显示模块等。该系统测量误差小、结构简单、造价低廉,可实现称重、去皮、设置物品单价、计算物品金额、报警等功能。
Electronic scale is one of the most commonly used measuring instruments in daily life. The system adopts resistance strain-gauge pressure sensor to convert the force to electrical signal and uses the single-chip STC89C51 as the control core. The circuit hardware consists of sensor module, control module, A/D conversion module, key module, display module and so on. The system has the advantages of little measuring error, simple structure and low cost, which can achieve the weighing, peeling, unit price setting, total goods counting and alarming functions.
