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,两者之间可通过WIFI进行数据通信。经测试,该药箱能够有效地帮助慢性病患者按时、定量、正确服用药物,适合在家庭中推广使用,具有较高的应用价值和实践意义。Based on the importance of drug therapy in clinical treatment, this paper analyzes the shortcomings of current drug reminder devices, and designs a multi-function electronic medicine box with STM32 F103 VET6 microcontroller as the control core. The system includes a display module, a voice module, and a data storage module. The display module cooperates with the voice module through the touch screen circuit and the LED indicator circuit to realize the function of reminding and guiding the medicine;the data storage module can realize the function of not losing the medication information when the power is off through the EEPROM storage circuit.After testing, the medicine box can effectively help chronic diseases patients to take drugs on time, in a quantitative and correct manner,and is suitable for popularization in the family, and has high application value and practical significance.

针对四轴飞行器飞行性能不稳定和惯性测量单元(IMU)易受干扰、存在漂移等问题,利用惯性传感器MPU6050采集实时数据,以经典互补滤波为基础,提出一种可以自适应补偿系数的互补滤波算法,该算法在低通滤波环节加入PI控制器,依据陀螺仪测得的角速度实时调节PI控制器补偿系数。飞行器姿态控制系统采用双闭环PID控制方法,姿态解算的欧拉角作为系统外环,陀螺仪角速度作为系统内环。最后,搭建以NI my RIO为核心控制器的四轴飞行器,通过Lab VIEW实现算法和仿真,实验结果表明,自适应互补滤波算法可以准确解算姿态信息,双闭环PID控制超调量小、反应灵敏,控制系统基本满足飞行要求。
