Life monitoring system
2008
The invention relates to a life monitoring system for monitoring a computer information and control system in a nuclear power station. The computer information and control system in the nuclear power station comprises at least one function server. The life monitoring system comprises a life signal generating module, a timing module, a diagnosing module and an alarming module; the life monitoring system sends a corresponding life signal to each function server in a preset time period; after the life signal accesses each key process of the corresponding function server in sequence, the functionserver sends a feedback signal, then the life monitoring system judges whether the exception appears according to the feedback signal and alarms when a failure occurs, so as to monitor an unavailablefault status of a KIC system from outside, verify the communication between the KIC system and a power-station automatic control system and particularly judge whether a path that the KIC system sendsan instruction downward meets the requirement of a customer; and when the KIC system is abnormal, the life monitoring system can give an alarm for an operator in a visible-audible way in time.
