随着自动化管理水平的提高,各种工程,尤其是大型水力发电工程或长距离引供水工程等,对安全监测自动化系统的性能要求日益提高。文中介绍了一种利用μC/OS-Ⅱ提供的管理机制,将工程安全监测单元的各种功能设计成相互独立又相互协调的不同应用任务的设计方法。基于μC/OS-Ⅱ的产品结构简洁,可并行运行多个不同任务,具有应用程序更新、升级方便、系统运行效率及可靠性双高等特点。基于μC/OS-Ⅱ的监测单元能很好地满足大型、复杂工程的自动化应用要求。 With the improvement of automation management, various kinds of engineering, especially large-scale hydroelectric power projects or long-distance water supply projects, are increasingly demanding the performance requirements of safety monitoring automation systems. In this paper, a management mechanism based on μC / OS-Ⅱ is introduced in this paper, and the various functions of the engineering safety monitoring unit are designed as independent and coordinated design tasks for different applications. Based on μC / OS-Ⅱ product structure is simple, can run multiple different tasks in parallel, with application updates, upgrades, system efficiency and reliability of double high. The monitoring unit based on μC / OS-Ⅱ can meet the automation application requirements of large-scale and complex projects well.
