MCS-51单片机智能温度控制 摘 要 单片微型计算机是随着超大规模集成电路技术的发展而诞生的，由于它具有体积小、功能强、性价比高等特点，把单片机应用于温度控制中，采用单片机做主控单元，无触点控制，可完成对温度的采集和控制的要求。所以广泛应用于电子仪表、家用电器、节能装置、机器人、工业控制等诸多领域，使产品小型化、智能化，既提高了产品的功能和质量，又降低了成本，简化了设计。本文主要介绍单片机在热处理炉温度控制中的应用，对温度控制模块的组成及主要所选器件进行了详细的介绍。,是一个非常重要的环节。控制精度直接影响着产品质量的好坏。本文研究的电炉是一种具有纯滞后的大惯性系统，传统的加热炉控制系统大多建立在一定的模型基础上，难以保证加热工艺要求。因此本文将模糊控制算法引入传统的加热炉控制系统构成智能模糊控制系统。 关键词：单片机；热处理温度控制；模糊 PID。 Abstract The single slice of microcomputers emerges with development of very large scale integration technology, because it has small , the function is strong , high characteristic of cost performance, applies the one-chip computer to temperature control, adopt the one-chip computer to do the top management unit, control contactlessly , can finish the requisition for collection and control of temperature . So apply to such a great deal of fields as electronic instrument , household appliances , energy-conservation fitting , the robot , industrial control ,etc. extensively, make the products miniaturized , intelligented , has already improved the function and quality of the products, have lower costs again, has simplified and designed. This text introduces the application of the one-chip computer in the temperature control of heat-treatment furnace mainly, composition and selecting to introduce the detailed one with device mainly of the temperature control module . And has written the suitable software procedure originally designed according to the concrete demand this text. Temperature in heat treatment craft is very important. Control precision effect directly the quality of the product. The electric stove is a kind pure great inertia system, and the traditional heat control system is based on some certain model, so is hard to satisfy the technological requirement.This paper will adopt fuzzy control algorithm to build a intelligent fuzzy control system.
