基于STM32单片机控制的智能水杯设计
<p>本设计介绍了一种基于STM32单片机控制的智能水杯,可利用插口式电源或无线充电底座为加热器提供能量,并在达到某种饮品所需温度时进行保温。水杯内置充电电池,可选用USB接口或无线充电。在水杯内部设置无线模块,用户利用手机App与水杯进行匹配进行加热操作,加热完后水杯会通过手机App和液晶显示屏实时反馈液体温度,通过指示灯显示电量情况等,给用户进行提醒。该智能水杯设计创新,实用价值较高。</p>
基于STM32F103单片机电流电压采集系统设计
<p>配电网中,各种配电终端的电流、电压、有功功率及无功功率等模拟量的采集是配电网自动化的重要环节。这些模拟量的采集也是各种仪器和家用电器的必要功能。因此,设计了基于嵌入式STM32F103单片机的交流电压、交流电流及有功功率的采集系统,通过电压互感器TV1005M和电流互感器TA1005M分别检测交流电压和交流电流值;屏幕或者手机APP和WiFi模块互联后,可以实时显示交流电压、交流电流、功率及
多功能电子药箱的设计与实现
<p>基于药物治疗在临床治疗中的重要性,分析目前服药提醒装置存在的不足,以STM32F103VET6单片机为控制核心,设计了一种多功能电子药箱。该系统包括显示模块、语音模块和数据存储模块。显示模块通过触摸屏电路和LED指示灯电路,与语音模块相配合,实现了服药提醒及指导的功能;数据存储模块通过EEPROM存储电路,能够实现掉电时服药信息不丢失的功能。并且为了实现电子药箱的智能化控制,开发了手机APP
