摘要 摘要

本文介绍了基于AT89S52单片机水温测量及控制系统的设计。系统硬件部分由单片机电路、温度采集电路、键盘电路、LED显示电路、继电器控制电路等组成。软件从设计思路、软件系统框图出发，逐一分析各模块程序算法的实现，通过C语言编写出满足任务需求的程序。本系统采用数字式温度传感器DS18B20作为温度传感器，简易实用，方便拓展。单片机以此对水的温度进行有效检测与报警，并以此进行水温的控制。基于单片机水温控制系统采用多电源供电，降低了系统各个模块间的干扰，还保证了电源能为各部分提供足够的工作电流，提高系统的可靠性。

关键词：水温控制 AT89S52 DS18B20

Abstract

This paper introduces the water temperature measurement based on AT89S52 SCM and the design of control system. The system hardware part of microcomputer circuit, temperature acquisition circuit, keyboard circuit, the LED display circuit, relay control circuit etc. Software from design idea, software system of block diagram, by analyzing the module program implementation of algorithm is, through the written in C language to meet the demand of the task program. The system USES the digital temperature sensor DS18B20 as temperature sensor, simple, practical, and convenient development. SCM in order to the temperature of the water carries on the effective detection and alarm, and based on which the water temperature control. Water temperature control system based on single chip by power supply, reduce the system between each module of the interference, ensures the power supply for the part provide enough work current,

Keywords: Water temperature control AT89S52 DS18B20
