摘要
设计了一种温度监控系统,讨论了系统硬件及软件设计方案。通过硬件设计,在环境现场放置AD590温度传感器,利用STC89C52单片机采集温度数据并显示当前温度,通过RS-485串口传回主控计算机,实现对环境现场温度的远程实时监控;在软件方面,下位机编写测温程序和1602液晶的显示程序,上位机采用Visual Basic6.0编写监控界面实现温度的实时显示、曲线绘制、高温报警等功能。
This paper designs a temperature monitoring system,and discusses the design of hardware and software system.Through the design of hardware,place the AD590 in the environmental site,and system collectes temperature data with STC89C52 and displays the current temperature,and returns the host computer with RS-485 serial port.It achieves the temperature of the environment site real-time monitoring remotely？鸦On the side of software,this paper program the program of Measuring temperature and 1602 LCD temperature display in the hypogynous machine,and the program of Monitoring Interface,to achieve real-time temperature display,curve drawing,high temperature alarm with Visual Basic6.0 in the epigynous machine.
