Design of interlock system for C-ADS injector I
An interlock control system based on a new redundant Programmable Logic Controller (PLC) and PROFINET protocol is developed as one of the key systems in China Accelerator Driven Sub-critical System (C-ADS) injector I for machine control and personnel protection. Signals from critical accelerator components are sent to this system for safety protection. Fault-tolerance and redundancy for high reliability are considered through the whole design, and reliability analysis of both redundant and non-redundant systems is done to meet the strict requirement. A control interface of Experimental Physics and Industrial Control System (EPICS) is developed and successfully used online. ©, 2015, Editorial Office of High Power Laser and Particle Beams.
