开封大学毕业设计（论文）题目：温度控制器的设计机电工程学院 李小草  摘 要本文设计了一个温度自动控制器。本设计以单片机（8031）为控制核心，外加硬件电路，将温度显示和数字控制集和于一体，实现智能温度控制。并采用软件程序实现升温的调节，能对加热炉的升温速度和保温时间严格控制。 单片机控制系统由微处理器和工业生产对象两大部分组成。本文是通过热敏电阻和单片机等，来实现对工程上一些系统的温度进行范围控制的过程。关键词：测温；PID算法；单片机；温度控制This paper describes the design of a automatic temperature controller. The design is based on SCM (8031) for the control of the core, the sur- hardware circuit, the temperature demonstration and the numerical control collection and in a body, realizes the intelligence temperature control. It realizes the elevation of temperature adjustment with the software routine, can heating furnaces elevation of temperature speed and the soaking time strict control. Microprocessor and microcontroller control system consists of two major components of industrial production of objects. This article is a microcontroller such as through the thermal resistance and to achieve a number of system engineering on the temperature range control of the process. KEY WORDS：Measure warm；PID algorithm； single flat machine and Temperature Controller 目 录 摘 要..............................................................I ABSTRACT..........................................................II 第1章 前 言......................................................1 1.1 概述.......................................................2 1.2 课题分析...................................................2 1.3 设计思路...................................................2 第2章 系统的基本组成及工作原理....................................3 2.1 系统的基本组成.............................................3 2.2 系统的基本工作原理.........................................3 第3章 测温电路的选择及设计........................................5 3．1 热电偶测温电路..............................................5 3.1.1 热电偶...................................................5 3.1.2 毫伏变送器...............................................6 3. 2 热敏电阻测温电路............................................6 3.2.1 热敏电阻..................................
