METHOD FOR GATHERING AND PROCESSING SIGNALS IN NUCLEAR REACTOR CORE MONITORING SYSTEM, AND DEVICE FOR ITS EMBODIMENT

摘要

nuclear power plants. SUBSTANCE: device has at least two parallel bus paths for passing signals from detector to two processors. All bus paths have identical hardware and software tools and are controlled using identical programs. Hardware tools include shared hardware (in particular, input device). These tools are controlled in each moment by only one of processors using its own bus path independently from other processors. When fault or error occurs in hardware of control path in shared channel part, control that uses it is switched off and other processors are informed about possibility to achieve control using other paths. EFFECT: independence of processors and paths, guaranteed validity of received parameters, when they are equal. 3 cl, 5 dwg
