摘　　要：设计了基于单片机和PC机的温度监测系统,温度传感器采用DS18B20。下位机采用AT89S52单片机,可以显示温度和超限报警。PC机作为上位机设定上下限报警温度,接收单片机的温度数据,处理后实时显示温度和绘制温度曲线,还实现了超限报警和保存数据功能。上位机利用Matlab强大的数值计算、图形显示和串口操作功能,具有友好人机交互界面,实现了温度动态监测。A temperature monitoring system based on SCM and PC is introduced, which uses DS18B20 as a temperature sensor. AT89S52 SCM as lower machine can display temperature and warn over limit. PC as upper machine sets upper and lower limit temperature and receives temperature data from SCM, then can display the temperature processed and draw temperature curve in real time. What＇s more, PC can warn over limit and save the data, Using matlab powerful numerical calculation, graphic display and serial port operation, PC has friendly man-machine interface and realizes the temperature dynamic monitoring.
