摘要
为解决传统人工方式对多点温度对象进行长期测量和控制带来的实时性差、投入过大等问题,基于AVR单片机设计实现多点温度监控的自动控制系统。以AVR单片机ATmega8为设计平台,利用LCD2004液晶显示器的强大显示功能、数字温度传感器DS18B20单总线特点,使用C语言和VB6.0,完成多点温度的测量、显示、曲线绘制及友好人机交互界面设计。经测试,对多点温度测量精确、人机界面监控效果良好。
In order to solve the poor real time,too large investment and other issues,which stem from the traditional manual acting for longterm multi-point temperature measurement and monitoring,the article puts forward a distributed temperature＇s monitoring control system based on the microcontroller uint ATmega8.Using powerful display function of LCD2004,and 1-wrie bus characteristics of digital temperature sensor DSl8B20,the system can monitor the real-time multi-point temperature,draw the changing curves of temperature with time and offer friendly and interactive interface.By testing,After testing,The consequence of temperature measurement is very accurate,and the effect of human-machine interactive interface is good.
