基于单片机的温度控制系统资料

摘要

本文提出的温度采集控制系统以单片机（AD590）为核心，由控制部分、显示部分和温度测量部分组成。该系统大部分功能通过硬件来实现，电路简单明了，系统稳定性很高。

这套温度控制系统可以方便地实现温度测量、温度显示等功能，并通过与单片机连接的键盘可以实时设定测控温度的下限，还可以连接相应的外围电路，在收到单片机发出的指令后对环境进行检测

本文首先描述系统硬件工作原理，并附以系统结构框图加以说明，着重介绍了本系统所应用的各硬件模块的功能和它的工作过程；其次，详细阐述了程序的各个模块及其实现过程。本系统的主要设计思想是以硬件为基础，软件和硬件相结合，最终实现各个模块的功能。

ABSTRACT

The design and implementation of temperature control system based on SCM (AD590), it makes up of control part, display part and temperature testing part. Most functions of this system are realized by hardware, the electric circuit is reliable, and the system can achieve higher stability.

The system can measure and display the temperature, set the limit figure of temperature by the keyboard which connects with SCM instantly, and still can link corresponding peripheral equipment to heat the environment up after received the instruction that SCM issued.

Firstly, the working principle of hardware is described in this paper which adds the structural block diagram for explanation. This paper emphatically introduces the functions and working process of each applied module. Secondly, this text expounds the functions of each module of program. The dominant thought of this text is that hardware is regarded as the foundation, software combining with hardware to actualize the functions.
