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STC12C5A60S2单片机的LED线阵显示装置
<p>LED 线阵显示装置, 分为 LED 线性旋转显示主机和图文录入器两部分。主机用直流电机带动由红绿 LED 组成的线阵旋转, 同时线阵按照时序依次切换显示状态, 在固定区域利用视觉暂留效果形成 16×16 点阵, 用以显示图文;图文录入器用 HMI 触控屏作为人机交互界面, 实现图文录入和回放功能。主机与图文录入器通过无线通信方式进行信息交互,可由图文录入器控制主机切换不同工作任务, 以及改
基于2.4G的双电机遥控船模控制系统设计
<p>以STC12C5A60S2单片机为控制核心,采用2.4G(JF24D)无线遥控模块进行无线发射与接收,设计了一种双电机遥控船模控制系统.该系统通过切换档杆实现前进后退,方向盘左右转动、暂停按钮等控制直流电机的正转、反转、暂停,使得电机驱动的遥控船模实现前进后退、左右转向、暂停等功能,有效解决了驱动功率小和船模之间相互干扰等问题,可广泛应用于遥控船模领域.</p><p>Using STC12C
无线传感器网络中基于模糊理论的决策级数据融合技术的分析
<p>摘要：无线传感器网络（Wireless Sensor Networks，wSN是由许多具有低功率无线收发装置的传感器节点组成，它们监测采集周边环境信息并传送到基站进行处理在某一时刻通过wSN采集的数据量非常大，如何正确、高效地处理这些数据成为当前WSN研究中的一个热点。传感器节点一般部署在恶劣环境中，一些偶然因素会使采集的数据中出现不准确的数据，用户依据这样的数据很难准确判断出被测对象的真实
