Description

technical field

[0001] The invention relates to the technical field of nuclear power plant instrumentation and control equipment, in particular to a nuclear power plant data collection device and method. Background technique

[0002] With the continuous development of network technology and information technology, Distributed Control System (DCS for short) is more and more widely used in nuclear power plants due to its fast data processing speed.

[0003] However, in the design of instrument and control systems in nuclear power plants, system capacity and speed have always been two factors that restrict each other. Specifically: if the capacity of the instrument and control system is larger, its processing speed must be reduced; and to make the instrument and control system faster , it is necessary to appropriately reduce the capacity of each power station.

[0004] For example, in the Chinese patent application with the Chinese patent application number CN201510294269.X, a...
