文档介绍：摘要
随着计算机在社会领域的渗透, 单片机的应用正在不断地深入,同时带动传统控制检测日新月益更新。在实时检测和自动控制的单片机应用系统中,单片机往往是作为一个核心部件来使用,仅单片机方面知识是不够的,还应根据具体硬件结构,以及具体应用对象特点的软件结合,以作完善。
本文介绍了单片机应用于电加热饮水机的一种设计方法,该电加热饮水机具有自动化程度高、安全性好、功能多、使用方便、功率小、加热快、可靠性高等特点。它以单片机AT80C51为核心,通过3个数码管显示温度和4个按键实现人机对话,使用单总线温度转换芯片DS18B20实时采集温度并通过数码管显示,并提供各种运行指示灯用来指示系统现在所处状态,如:温度设置、加热、停止加热等,整个系统通过四个按键来设置加热温度和控制运行模式。并详细地论述了以单K机为处理器的电加热饮水机的硬件、软件设计、系统编程和抗干扰设计等方面的问题。本系统以ATMEL公司的AT80C51单片机为核心,由DS18B20、信号处理电路、键盘控制电路、LED显示电路、输出控制电路等构成。

ABSTRACT
Along with puter in the social sector ration and MCU application is continuously
thorough , and push the traditional control test on the new beneficial update. In real time detection and automatic control of the puter application system , the MCU is often as a ponent to use, only MCU aspects knowledge is not enough , should according to the specific hardware structure , and the specific application of the characteristics of the object bination to be perfect . This paper introduced a single-chip puter which used in electric heating water dispenser as a design method, the electric heating water dispenser with a high degree of automation, security and multi-functional easy to use,small power,heating quickly , and high reliability. AT80C51 microcontroller as the core of it, through the three temperature digital display and 4 keys to achieve man-machine dialogue, the use of single-chip bus temperature conversion temperature DS18B20 real-time acquisition and through the digital display and offers a variety of operating light to indicate system now live in the state, such as: temperature setting, heating, and stop heating, the entire system through the four buttons to set the heating temperature and control the operating mode . The paper described in detail by the single-chip processor power for heating water dispenser hardware,software design, system design, programming and anti-jamming problems. The controller ATMEL Corporation AT80C51 single-chip puter as the core, by the DS18B2
