Strategy of diagnosis and test in ICCS of large-scale laser facility

Integrated Computer Control System (abbr. ICCS) of large-scale laser facility uses a scalable software architecture to manage more than 10,000 control points to operate 48 powerful laser beamlines, provides for the integration of all elements of laser and target area distributed subsystems to form an overall operational control system. Fault detection and diagnosis test are the important technique to ensure the system's safety, reliability and healthy manage. This paper is an overview of the diagnostic and test strategy used in ICCS of large-scale laser facility, including design rules, task decomposition strategy, classification strategy, the scheme of on-line diagnosis and offline diagnosis, diagnosis process and data preconditioning about data standardization and quality control.
