CROSS-BASE ALARM LINKAGE METHOD AND DEVICE FOR NUCLEAR POWER PLANT

摘要

A cross-base alarm linkage method and device for a nuclear power plant. The method comprises: monitoring alarm linkage systems of a plurality of bases in real time (S101); judging whether the alarm linkage system of each of the bases operates normally (S102); if so, the alarm linkage system of the current base achieving security and protection monitoring (S103); if not, an emergency command centre system judging the alarm level of an emergency alarm signal sent by the alarm linkage system of the current base (S104); according to the alarm level, starting corresponding permission management (S105); according to the emergency alarm signal, invoking and executing a plan (S106); when an illegal attack occurs, generating an alarm signal (S401); the command centre extracting site alarm position information from the integrated alarm signal, then invoking an image collection device group to collect a site image, and automatically popping up the site image on a monitor so as to understand the authenticity and seriousness of an unexpected event in time (S405); giving audible and visual alarms simultaneously (S406); and recording the image of an alarm region which is automatically popped up while the alarms are given (S407).
