μC/OS-II?下温度监控系统设计
摘 要:随着信息化,智能化,网络化的发展,嵌入式系统技术也获得广阔的发展空间,前嵌入式技术已成为通信和消费类产品的主流技术。μC/OS-II是专为微控制器系统和软件开发而设计的公开源代码的抢占式实时多任务操作系统内核,和linux等其他实时操作系统相比具有执行效率高、占用空间小、实时性能优良和可扩展性强等特点, 最小内核可编译至 2KB 。?
本文详细阐述了监控系统组成结构和软硬件设计。系统设计的硬件包括电源模块、显示模块、温度采集模块、超限报警模块、按键控制模块、JTAG电路和主处理芯片。系统软件设计首先完成μC/OS-II嵌入式实时操作系统的移植,并设计了4个任务,分别是温度检测任务、显示任务、报警设置任务和按键任务4个任务组成。检测任务采集温度送至控制器。显示任务实现温度实时显示。报警设置任务设置温度上限和下限,如果超出限值则报警。系统移植μC/OS-II嵌入式实时操作系统成功,按键响应及时,温度显示清晰稳定。

μC / OS-II Temperature Monitoring System
Abstract:With the information, intelligence, network development, embedded systems technology has won broad space for development. the former communications and embedded technology has become mainstream consumer products. μC / OS-II is designed for micro-controller system and open source software designed for preemptive multitasking real-time operating system kernel.Compared with other real-time operating systems such as linux with the implementation of high efficiency, small footprint, real-time performance and superior scalability and so on. the minimum core can be compiled from 2KB.
This paper describes the structure and composition of the monitoring system software and hardware design. System hardware including power modules, display module, temperature data acquisition module, limit alarm module, key control module, JTAG circuit and the main processing chip. System software design to complete the μC / OS-II real-time embedded operating system migration. Second, the design of the four tasks namely the temperature detection task, showing task,
