ATS主备研究与软件建模

为了实现ATS系统的高可用性,ATS的关键设备需要采用主备机制,对于不同的设备所采用的主备机制也有所差异。通过分析不同的应用场景,提出了适用于ATS的三种主备切换模式,并对主备算法进行研究分析以及对不同切换模式进行统一软件建模,简化软件的开发工作与设备部署的难度。通过设计的软件模型,能够很好的解决了ATS复杂的部署环境下主备切换的功能,满足ATS系统的可靠性的需求。

In order to realize the high availability of ATS system, for the major equipment of ATS system should use the activestandby mechanism, and the active-standby mechanism is different in different equipment. According to the actual operation scene, three active-standby methods were proposed, analysis these methods and unify modeling of these methods, it could reduce the difficulty of the software development and the equipment deployment. Through this designed mode, It could ftdfill the requirements of auto switched the backup equipment for different scene while the active equipment is out of order, and it could fulfill the reliability requirement of the ATS system.
