【正文】 system of intelligent measurement and control. Main purpose is to use a microcontroller design temperature controller through the use of PID control algorithm, makes temperature in a given temperature values. Introduced a microcontrollerbased AT89S52 the temperature measurement and control devices. The device can achieve the right temperature measurement, and set value based on the environmental temperature regulation, temperature control to achieve the purpose. Control algorithm based on digital PID algorithm. The system is the core ponent AT89S52 SCM. First established temperature control model, the rational distribution of hardware and software to choose a suitable heating mode, controlling the model to meet the requirements of different 2 stages. System Acquisition Module 18 B20 used as a temperature sensor temperature ponents, The control module is used AT89S52 MCU control solid state relay conduction with the deadline, thus control the heating voltage and broken links, so the control is a sensitive, reliable, antijamming capabilities, and so on merit. This paper focuses on the hardware configuration of the system, the main part of the role and system software design process. The design of the microcontroller temperature control system of the basic theory and application of techniques were more prehensive presentation. 【 Keywords 】 :Microcontroller, temperature monitoring, temperature sensors. 一、 系統(tǒng) 方案 設(shè)計 與 論證 方案一 采用 8031 作為控制核心 ,用熱敏電阻采集溫度， 以使用最為普遍的器件ADC0809 作模數(shù)轉(zhuǎn)換 ,控制上使用對電阻絲加電使其升溫和開動風(fēng)扇使其降溫。本文重點(diǎn)闡述了系統(tǒng)的硬件構(gòu)成、 各部分的主要作用及系統(tǒng)軟件的設(shè)計過程 。首先建立控溫模型，通過硬件的合理配置及用軟件選擇合適的加熱模式，使控制滿足模型中不同階段的要求?？刂扑惴ɑ跀?shù)字 PID 算法。 介紹了一種基于 AT89S52 單片機(jī) 的溫度測控裝置。
