嵌入式温度控制

1、.本课程设计的目的（1）使学生掌握嵌入式开发板（实验箱）各功能模块的基本工作原理；（2）培养嵌入式系统的应用能力及嵌入式软件的开发能力；（3）使学生较熟练地应用嵌入式操作系统及其API开发嵌入式应用软件；（4）培养学生分析、解决问题的能力；（5）提高学生的科技论文写作能力。设计要求：设计一个基于ARM微处理器和以CLinux的嵌入式温度控制系统，要求采用PID增量 算法实现对电烤箱的温度控制，并且在达到温度控制要求的同时使用4X4小键盘和触摸屏 作为输入，使用了 LCD、串口、网口和音频等作为输出，使得系统具有友好的人机界面。 系统工作的基本原理为：温度传感器把电烤箱的温度转换成电信号经过测量

2、电路、滤波器和 放大器，输入到ARM微处理器的A/D输入端口 AIN。然后ARM微处理器执行PID控制程 序，根据从AIN输入的电压值，经过PID算法得出输出值。通过PWM脉宽可调功能，把 控制量转换成占空比可调的脉宽，经过放大器和功率放大器后驱动电阻，达到控制功能。具 体设计任务如下：（1） 系统总体设计；（2）系统硬件电路的设计；（3）操作系统的分析与移植；（4）系统应用软件的设计；（5）系统硬件和软件的调试。Fedora 10的安装加New TearnOpen Existing VM or Team目 VMware WorkstationFile Edit View VM Team Wi
