Description
This paper presents the design, implementation, and operational performance of the Low-Level Radio Frequency (LLRF) control system for SHINE. The system adopts a two-layer software architecture to achieve integrated automation in RF field stabilization, fault handling, and multi-cavity coordination. The lower layer utilizes EPICS IOCs implemented on Zynq SoC platforms to provide real-time cavity control. This layer supports multiple operational modes including normal beam operation, maintenance procedures, and automatic fault recovery.The upper management layer coordinates all cavities through distributed EPICS PV monitoring and implements system-wide fault tolerance logic. Key features include real-time status monitoring, automated fault analysis, and coordinated recovery. Notable innovations include the EPICS-Zynq integration for low-latency control, dynamic reconfiguration capability for different operation modes, and data-driven fault diagnosis.This control architecture represents a significant advancement in accelerator automation, combining real-time hardware control with intelligent system management. The implementation provides a robust solution for SHINE's demanding performance requirements while offering tools for efficient operation and maintenance.
