Design and Implementation of Functional Safety Configuration Software
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.
