摘要
针对SIS系统对可靠性、可用性以及可维护性的高标准严要求,设计开发了在麒麟系统上运行的满足安全完整性SIL3 以及IEC61508 标准的功能安全组态软件SafeSmartIC.该软件针对全国产软硬件平台进行开发,采用了模块化的组件分布方式,基于虚拟的消息总线方式进行组件间的信息交互,降低了模块间的耦合程度;设计了基于多重报文交互校验和时间维度管理的组态下载方案,保证了组态下载过程的安全性与准确性.设计了组态软件以及符号库的版本耦合管理方案,实现了组态文件的版本管控以及组态的安全升级功能;设计了组态程序负载估算策略,保证在实际工程应用时控制器的运行负载维持在安全稳定水平.
Abstract
The SafeSmartIC functional safety configuration software has been designed and developed to meet the high standards of reliability,availability,and maintainability required by the SIS system.It runs on the Kirin system and complies with the safety integrity level SIL3 and the IEC 61508 standard.The software is developed for a national software and hard-ware platform,featuring a modular component distribution approach and utilizing a virtual message bus for inter-component communication,reducing the coupling between modules.A configuration download scheme based on multiple message in-teraction verification and time dimension management is designed to ensure the security and accuracy of the configuration download process.A load estimation strategy for configuration programs is developed to maintain the controller's operational load at a safe and stable level during actual engineering applications.
