实时操作系统VxWorks在海洋观测系统的应用

Application of the Vx Works Real-Time Operation System in Ocean Observation

随着对海洋观测系统实时性与可靠性要求的提高,在系统中应用实时操作系统(Real Time Operation System,RTOS)已经成为提升其整体性能的重要手段之一。但是由于缺少相关的成功应用案例,并且存在潜在的技术和资金等方面的风险,使得RTOS技术在海洋观测领域的具体实施存在一定的不确定性。在前期大量调研和技术研究的基础上,对在海洋观测领域应用RTOS技术的优势和局限性进行了分析,提出了若干类适合应用RTOS技术的业务类型,并给出了开展研究工作的建议。在此基础上,以VxWorks系统为例,针对两类具体应用场景,分别给出了典型的RTOS系统组成和架构。通过适当配置,这两个模型可以演变为多个具体业务系统,并为今后工程应用提供借鉴经验。

With ever-increasing real-time and reliable requirements for ocean observation, the application of the real-time operation system（RTOS） in this field has become a necessary solution to improving the overall performance. However, due to the lack of related successful cases and the existence of potential risks in fund and technology, how to utilize RTOS in the engineering projects of ocean observation is not quite clear so far. Based on prior surveys and technological study, this paper analyzes the advantages and limitations of applying RTOS in ocean observation, and presents several service types suitable for RTOS and some suggestions for carrying out research tasks. Furthermore, using VxWorks as an example, two system architecture models specialized in representative application scenarios have been proposed. Concrete application systems can be implemented through reasonable configurations of the two models, which provides application references for future related projects.
