基于单片机的多功能电子医药盒设计与实现

摘 要

飞速发展的嵌入式设备技术为医疗的发展带来了无穷无尽的发展动力。计算机发展

已经进入移动时代且日益普及，将移动的主体通过网络与庞大的数字空间结合在一起，

让随时随地的医疗监护成为可能。现代社会的快节奏生活让我们可以在忙碌的时间利用

计算机科学技术备忘我们的生活计划，让我们更加便利地规划我们的生活。

使用多功能电子医药盒能大大提高人们的生活效率，可以给年轻人在忙碌的工作时

提醒吃药的时间；可以提醒老年人按时吃药、安全吃药。

本次设计是在运用成品嵌入式计算机的基础上，使得人类的语言无线遥控单片机的

芯片方面，ATMEGA16L微处理器和凌阳SPCE061A微处理器以及二者的组合应用是三

种备选设计方案。两种微控制器都具有丰富的片上系统资源，加上一切辅助电路可实现

语音辨识功能，完成各种功能的要求。指令系统上也都支持C语言，给程序员的编写，

和读取提供了便捷。在语音指令方面，可利用单片机的特定人语音识别功能来实现。首

先对电子药盒进行训练。以语音命令转换为数字信号的方式存储在单片机FLASH存储器

中。在需要控制药仓开启的时候，单片机通过采集声音信号，并量化处理为数字信号后，

与存储器中预先存储的控制命令进行辨识，结果以字节数据方式从无线模组发出，药盒

接收到控制指令后，控制驱动芯片和舵机，使电子药盒完成响应动作。

development has brought endless power. Computer development has entered the era of mobile

and the increasing popularity, the main body of will move through the network and huge

number space together, make it possible for anywhere in a medical ward. The fast pace of

modern society life let we can in the busy time using computer science technology to cheat

our life plan, let us to plan our life more convenient.

people's life, can take medicine to the young people in the busy work to remind of time; Can

remind the elderly security to take medicine on time.

peripheral circuit, power circuit, audio circuit, I/O circuit and other peripheral circuit can

make the various functions of single-chip microcomputer. The reset button, the state of light

and so on the function of the circuit is necessary. In terms of chip ATMEGA16L

microprocessor and sunplus SPCE061A microprocessor, and the combination of the two

applications is three alternative design scheme. Both micro controller has rich on-chip system

resources, plus all the auxiliary circuit can realize the function of speech recognition,

complete with the various demands of the function. Instructions on the system support the C

language, and also give programmers write, provides a convenient and read. In the aspect of

voice commands, can use MCU speaker-dependent speech recognition. First of all to

medicine for training. By voice command can be converted into digital signal is stored in the
