智能电子秤的原理与分析
摘要：随着计量技术和电子技术的发展，传统纯机械结构的杆秤、台秤、磅秤等称量装置逐步被淘汰，电子称量装置电子秤、电子天平等以其准确、快速、方便、显示直观等诸多优点而受到人们的青睐。电子秤向提高精度和降低成本方向发展的趋势引起了对低成本、高性能模拟信号处理器件需求的增加。通过分析近年来电子衡器产品的发展情况及国内外市场的需求，电子衡器总的发展趋势是小型化、模块化、集成化、智能化；其技术性能趋向是速率高、准确度高、稳定性高、可靠性高；其功能趋向是称重计量的控制信息和非控制信息并重的“智能化”功能；其应用性能趋向于综合性和组合性。电子称主要以单片机作为中心控制单元，通过称重传感器进行模数转换单元，在配以键盘、显示电路及强大软件来组成。电子称不但计量准确、快速方便，更重要的自动称重、数字显示，对人们生活的影响越来越大。
