基于新型安全架构的HEPS插入件安全控制系统

Safety control system for HEPS insertion device based on new safety architecture

高能同步辐射光源(HEPS)插入件控制系统的主要功能是实现插入件磁间隙的开合运动控制。插入件控制系统的安全运动对插入件、储存环和光束线站的设备和人员安全至关重要。针对HEPS插入件控制系统的安全需求,研究了工业安全设计的标准和规范,在国内外同类型插入件控制系统中首次设计和实现了基于新型安全架构的安全系统。安全系统的设计和实施符合国际安全标准,并达到了安全完整性三级的高安全等级。该系统已成功应用在HEPS测试束线低温波荡器中,并完成了系统性的测试。测试结果表明,HEPS插入件安全系统实现了所有预期的安全指标,达到了高安全等级工业控制系统的标准。

The control system of Insertion Device(ID)for High Energy Photon Source(HEPS)is mainly responsible for the opening and closing motion control of the magnetic gap of ID.The safe movement of the ID control system is essential for the safety of ID,storage ring and beamline station.Based on the safety requirements of HEPS ID control system,a high-level and multi-level safety system based on the new safety architecture has been designed and applied.It is the first time that this kind of safety system has been applied to the same type of ID control system worldwide.The safety system is designed and implemented in accordance with international safety standards and achieves the high safety level of Safety Integrity Level.The safety system has been successfully applied in the Cryogenic Permanent Magnet Undulator(CPMU)for HEPS,and the systematic tests have been accomplished.These tests results show that the safety system meets all the expected safety specifications,and achieves the standard of industrial control system with high safety level.
