Abstract

The invention provides a data collection device and method of a nuclear power station, and belongs to the technical field of instruction control equipment of the nuclear power station. The device comprises a system control layer and a monitoring control layer; the system control layer is provided with a data collection unit and a controller unit; the data collection unit comprises data input / output interfaces, and the data input / output interfaces communicate with the controller unit via network communication board cards; logic operation is carried out on data collected by the network communication board cards according to a predetermined algorithm in the controller unit; the monitoring control layer is provided with a clock calibrating source; and time of the network communication board cards is calibrated by the controller unit, and the network communication board cards marks data transmitted via data channels connected with the data input / output interfaces with labels. A three-layer configuration including the controller unit, the network communication board cards and input / output interfaces is used, the network communication board cards marks the collected data with labels, so that the processing speed of the controller unit can be improved under the condition that the capacity of the instruction control equipment is not reduced.

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...
