本文以单片机AT89C52集成芯片为信息处理核心，提出电子秤的硬件电路设计方案，详细的分析了各单元的硬件电路，给出了仪器电路设计和软件流程，及相关电路图、原理图，最后介绍了系统的硬件调试和软件调试。
简易电子秤的设计应符合以下要求：
功能：　　1>以数字显示被称物体的重量，单位克或盎司（g或oz）
　　　　2>去皮功能（开机或者手动去皮）,去皮范围不超过最大量程
　　　　3>超量程报警功能
　　　　4>单位转换功能
指标：　　1>量程：0~2000g（0~70.55oz）
2>精度：1g（0.04oz）(In this paper, microcontroller AT89C52 integrated chip for the core of information processing, electronic scales proposed hardware circuit design, detailed analysis of the hardware circuit of each unit, given the instrument circuit design and software flow, and related circuit diagram, schematic, and finally introduced System hardware debugging and software debugging.
Simple electronic scale design should meet the following requirements:
Functions: 1> The figure shows the weight of the object in grams or ounces (g or oz)
2> peeled function (boot or manual peeled), peeled range does not exceed the maximum range
3> over-range alarm function
4> unit conversion function
Index: 1> Range: 0 ~ 2000g (0 ~ 70.55oz)
2> Accuracy: 1g (0.04oz))
