本文首先介绍了温度控制系统以及PID增量算法,然后着重介绍了系统的组成和控制过程的具体实现。在实现过程中,本系统着重在人机界面上做了工作,在达到控制要求的同 时使用4×4 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人机界面更加友好。 关键词:温度控制,S3C44B0X,PID Abstract: Firstly, this paper describes the temperature control system and PID increment arithmetic, then, mainly describes the composing of the system and the achieving of the control process. In the control process, the interface is outstanding in this system, besides reaching the target, using 4×4 keyboard, touching screen as input devices and LCD, serial, Ethernet, IIS as output devices so as to make the interface better.
