CONTROL SYSTEM FOR SAFETY OF NUCLEAR POWER PLANT Russian patent published in 2016 - IPC H04W12/00 G21C7/36 

FIELD: automated control systems.

SUBSTANCE: invention relates to systems of automated monitoring and control of nuclear power plants (NPP) in designing control systems safety (UID) of NPP. System contains multiple identical channels of safety, each channel includes station of input-output of signals of the process of STS_1-n, stations of priority control actuators SLV_1-m, connected with block standby station, and controller of automation the safety of equipment SC. Station STS comprises communication modules with process SME_1-k and communication module-interface converter of communications PEAK tire SVV SB. Station SLV contains modules priority control actuators of MCP_1-e and communication modules: communication module voting MCG and module voting MG tire SB SVV. Each safety channel additionally comprises controllers of automation of normal operation KA_1-s, which are connected to the stations CBB_1-n, stations SLV_1-m at redundant tires ENL of normal exploitation, built based on switched Ethernet interface, radial structure of connection of network commutators and special communication protocol level data, and with system of normal operation at standby tire EN normal exploitation.

EFFECT: increase of reliability of security and protection against failures, extension of diagnostic capabilities of UID, and reduce of time of rehabilitation and improve of UID readiness.
