基于单片机的温度控制系统的设计

摘 要本文介绍了基于单片机的温度控制系统，阐述了系统软硬件的设计方法和工作原理。温度传感器和精密电阻构成的电桥将温度信号转变成电压信号，经过差分放大电路和 A/D 转换器后输入单片机。单片机根据模糊控制算法进行控制，输出脉冲信号通过继电器控制加热量，从而将温度控制在设定值。软件部分主要介绍了 proteus 和模糊控制算法。采纳了模块化设计思想，优化了软件程序以简化外部硬件电路，程序可读性强，提高了系统的功能，降低了生产成本。该系统具有温度实时测量、显示和控制三种功能。有效的减小了超调量和静态误差，缩短了调节时间。对今后的综合实验的开发具有有用价值。关键字：单片机；温度；模糊控制；继电器 AbstractThe paper introduces the temperature control system based on single chip, expounds the system hardware and software design method and principle of work. The temperature sensor and precise resistance constitutes the bridge will temperature signal into voltage signal, after difference amplifying circuit and after the A/D converter input microcontroller. SCM according to the fuzzy control algorithm, the output pulse signal control by relay control, which will add heat temperature control in value.Proteus mainly introduces the software and fuzzy control algorithm. Using the idea of modular design, optimization software program to simplify the external hardware circuit, procedures, and improve the system of strong readability of function, reduce the production cost. This system has the temperature measurement, display and control functions. Effectively reduced the overshoot and static error, shorten the time. The comprehensive experiments for future development of practical value.Key words: Single chip microcomputer；Temperature；Fuzzy control；SSR目 录1 概述....................................................11.1 温度控制系统的任务................................11.2 温度模糊控制系统的进展趋势........................11.3 毕业设计的内容与安...
