基于AT89S52多点温度控制器的设计

摘要

本文介绍了由AT89S52单片机为核心,实现对温度(0~100℃)的自动或手动控制的系统。系统通过DS18B20采集温度信号,并传送给单片机。并由单片机进行相应处理,从而实现温度控制的目的。且可通过键盘设定温度,LED显示当前温度值。

论文概述了DS18B20温度传感器的发展及基本原理,介绍温度传感器的原理及特性。对于温度传感器存储器的结构和使用要求做了一个详细的说明。而后介绍多点温度控制功能实现的原理与程序设计。最后对系统的整体结构进行了阐述。

文章的最后总结了整个系统的性能和特点,提出了值得进一步研究和优化的地方,并展望了其应用前景。

Based on the AT89S52 multi-point temperature controller design

Abstract

In this paper, from AT89S52 microcontroller as the core, and the temperature (0~100 ℃) the automatic or manual control of the system. DS18B20 chip temperature system, through acquisition temperature signals, and digital signal transmitted to the SCM. SCM by the corresponding treatment in order to achieve the purpose of temperature control. And that the system can be set through the keyboard temperature, LED display the current temperature. Here we made some improvements, truly a "multi-point" temperature measurement and control.

First of all papers outlined the DS18B20 temperature sensor development and basic principles of temperature sensors on the principles and characteristics. The temperature sensor memory of the structure and the use of a request to do a detailed description. Then introduced multi-point temperature controls and procedures to achieve the principles of design.

Finally, the system's overall structure has been elaborated.

The final article summed up the whole system's performance and characteristics, made worthy of further study and optimize the place and prospects in its application.

Key words: AT89S52 DS18B20 multi-point temperature control
