饮水机温度控制的系统设计与仿真

摘要

本文设计并实现了一种饮水机温度控制系统。其硬件系统以AT89C52单片机为核心，用温度传感器DS18B20实现温度控制，用液晶屏显示实时温度、时间与预设温度，制作数字温度计，并可实现温度预警控制。单片机系统的软件设计采用C语言进行编程，应用软件采用KEIL和PROTEUS仿真软件模拟实现控制过程。该饮水机控制系统是基于单片机的计算机检测技术的软硬件开发的一种应用，不仅可以创造良好的经济效益，还可优化饮水机温度控制系统。

The Design and Simulation of Drinking Machine Temperature Control System

ABSTRACT

This paper introduces a water dispenser temperature control system.This system hardware design takes AT89C52 as a core ,and realizes the temperature control with temperature sensor DS18B20.The actual temperature and the preinstall temperature are displayed with the LCD, the simple intelligent temperature control system digit thermometer is manufactured ,and may realize the temperature early warning control.The software programming uses c language to carry on the programming.The application software uses KEIL and the PROTEUS simulation software realizing the controlled process.The water dispenser control system is based on an application of the single chip computer hardware and software development of detection technology can not only create a good economic benefits ,but also optimize the fountains temperature control system.

Key word :the microcontroller AT89C52 ;DS18B20;temperature control.
