本文开展了基于九点控制器算法的温度控制系统的研究,主要设计了温控系统的软件 设计,设计了以C8051 单片机作为核心的嵌入式系统,并配有键盘和液晶显示组成小型操作系统,可实现信号调理、数据采集、数据显示、键盘控制、数据计算等功能,采用SmallRTOS 实时操作系统,完成实时操作系统的移植。设计了液晶显示键盘扫描、输出控制、算法实现、信号采样等任务模块。 关键字: 温控;嵌入式系统;实时操作;控制 Development of Temperature Control System based on Nine-o’clock Controller Algorithm Wei Wendai uangXi University School of Computer,Electronics and Information 530001 Abstract: It studies the Nine-o’clock controller system to the temperature, mainly designs the oftware design of the temperature control system. On the software, using SCM C8051F020, it esigns an embedded system, which is equipped with a keyboard and a LCD. Thus, it has functions such as signals-control, keyboard-control, data collecting, data-display and data calculating. It designs the LED keyboard display module, output control module, algorithm implementation and signal sampling module based on Small RTOS operating system.
