Nuclear power plant redundancy alarm system using field data collection devices and alarm logic sequence control device

摘要

The present invention provides a dualized warning system for a nuclear power plant using a field data collecting device and a warning logic sequence control device. In the system, an input unit for receiving field data of the nuclear power plant is dualized; accurate official global time data is added to event generation data; and a data network between the warning logic sequence control device and the field data collecting device of the warning system is dualized. In the present invention, various kinds of event data sensed or generated by main field facilities (10) are collected through an input unit (13) of a field data collecting device (12) inside a main control station (14); various kinds of data computed by the main control station (14) are outputted through a dual data line made up of output module 1 and 2 (15, 16); each of the dual outputs outputted from the field data collecting device (12) passes through VLAN 1 and VLAN 2 and warning sequence control device 1 and 2, respectively, and is applied as lighting data and warning data to a corresponding display panel of a main control station warning window (21) made up of tile-shaped display windows; and the dual outputs outputted from the output module 1 and 2 (15, 16) of the field data collecting device (12) through the VLAN 1 and VLAN 2 are provided for a main computing server (17) and a monitoring system (18).
