基于单片机和传感器的电子秤系统教学设计与实现
<p>本设计主要目的是满足一般家庭和中小型菜市场零卖商贩使用,其电子秤的称重量程在0—25kg之内,精度高达1g,并具有计价功能,为商贩和顾客提供最直接的交易信息,方便买卖双方交易,减少双方欺诈。为实现这一目标本设计采用单片机STC89C51控制,并选用24位精度的HX711A/D电子秤专用模块,液晶显示屏选用JLX12864G-085-P液晶模块。本设计电路简单完整、元器件的选择性价比很高,性能
多功能电子秤设计
<p>针对现如今日常生活和生产的方方面面都需要对物体的重量进行精准测量的问题,设计了这款多功能语音电子秤。该设计以STC89C52RC单片机为核心,使用电阻应变式压力传感器、HX711AD转换模块、WT588D语音模块和DS1302时钟芯片来实现,通过LCD1602来进行数据显示。根据设计的需要,绘制出了相应的电路原理图,制作了PCB板,进行了焊接和调试。根据设计功能编写了软件程序,并且进行了对应

基于IGBT的750kVA三相二极管箝位型三电平通用变流模块设计
<p>IGBT关断电压尖峰是其中的主要问题，解决它的最有效方法是采用叠层母线连接器件。针对二极管籍位型三电平拓扑两个基本强追换流回路，本文用ANSOFT Q3D软件比较研究了三类适用于多层母线排的叠层方案，并提出了一种新颖的叠层母线分组连接结构，结合特殊设计的吸收电容布局，减小了各IGBT模块的关断过冲，省去阻容吸收电路，并优化了高频电流在不同电容间的分布，抑制电解电容发热。通过理论计算与仿真两种
高速ADC、DAC测试原理及测试方法
<p>随着数字信号处理技术和数字电路工作速度的提高，以及对于系统灵敏度等要求的不断提高，对于高速、高精度的ADC、DAC的指标都提出了很高的要求。</p><p>比如在移动通信、图像采集等应用领域中，一方面要求ADC有比较高的采样率以采集高带宽的输入信号，另一方面又要有比较高的位数以分辨细微的变化。因此，保证ADC/DAC在高速采样情况下的精度是一个很关键的问题。</p><p>ADC/DAC芯片的性
