基于单片机的精密温度控制系统的设计与实现

摘要

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 ane displayed with the nixie tube, the simple intelligent temperature control system digit thermometer is manufactured, and may realize the temperature early warning control. The software programming uses the assembly language to carry on the programming. The application software uses KEIL and the PROTEUS simulation software realizing the controlled process. This intelligent temperature control system is based on the mouitor technology of software and hardware development and faces the object high-level visualization procedure development organic synthesis. It has the very big advantage to temperature control' s development. Not only will create the good economic efficiency, but also may propose the simplification which the high temperature will control.%文中系统硬件系统以AT89C52单片机为核心,用温度传感器DS 18 B20实现温度控制,用数码管显示实际温度与预设温度,制作数字温度计,并可以实现温度预警控制.单片机系统的软件编程采用单片机汇编进行编程.应用软件采用KEIL和PROTEUS仿真软件模拟实现控制过程.温度控制系统是基于单片机的计算机检测技术的软硬件开发和面向对象的高级可视化程序开发的有机结合,对温度控制的发展有很大好处,不仅可以创造良好的经济效益,还可提高温度控制的简单化.
