The Research and Application of Alarm Card Online Update Approach on ADACS_N Platform
Fuqing Units 1～4 adopts the plat wide digital control system(DCS),the DCS level 2 uses the ADACS_N platform of Atos,which needs to update the alarm due to design changes,picture optimization and other needs.However,the ADACS_N platform has no online update function,so that the electronic alarm cannot be updated synchronously with the paper alarm.By analyzing the design principle of alarm card of the ADACS_N platform,the paper analyzed the alarm card database saving and reading path on ADACS_N Severs,including OWP workstation,data storage sever and maintenance engineer station.Based on the study,a model framework is established to realize the online update function of alarm card on the ADACS_N platform,and developed the alarm card online update tool software script.The verification test results show that the online update tool can achieve expected function,When the sever fails,its data can be synchronized after the sever is restarted.Meanwhile,the load disturbance of the KIC platform during the online updating of the alarm card meets the design requirements.
