摘　　要：针对传统的桌面秤在节能省电,操作方式等方面存在的一些缺陷,设计了一种基于STC89C516RD+的数字式电子桌面秤;主要介绍了电子桌面秤的硬件系统框架及其关键功能模块;硬件电路采用层次式设计模式,使硬件系统模块化程度和可读性增强。数字式桌面秤的最大量程为30kg,最小检定分度值为10g等;根据《固定式电子秤GB/T 7723-2002》的测试和标定结果表明,整个系统不仅架构简单、操作灵活、巧妙节能,而且具有较强的电磁兼容性,所有称重技术指标均达到国家标准III级等级。A kind of digital electronic desktop scale is designed in order to solve the defects in terms of power saving and operations. The hardware system framework of the electronic desktop and its key function modules are mainly described. The hardware is designed in hi erarchieal mode and thus enhanced the degree of modulation and readability. The maximum scale range of the digital desktop scale is .＇~0kg, and the minimum scale division value is 10g, etc. The whole system is tested and calibrated according to the ＇ stationary electronic scale GB/ T7723 2002＇, and it shows that the whole system reaches the national standard grade III level with simple structure, flexible operations. low power and strong electromagnetic compatibility.
