Nuclear power plant-based SOE data acquisition method

Abstract

The invention provides a nuclear power plant-based SOE data acquisition method. According to the nuclear power plant-based SOE data acquisition method, signal acquisition devices which are in one-to-one correspondence with nuclear power plant filed apparatuses, and an SOE processor are provided, wherein the SOE processor is a single-chip microcomputer. The nuclear power plant-based SOE data acquisition method includes the following steps that: the signal acquisition devices acquire the states of the nuclear power plant filed switching apparatuses real time, and transmit the acquired states to the SOE processor; and the SOE processor performs processing according to the states of the switching apparatuses and change situations of the states, so that the operation situations of a current switching apparatus can be obtained, wherein the operation situations are divided into events, interferences or stable states, if the operation situation of the current apparatus is an event, the SOE processor reports the event to a control station. With the nuclear power plant-based SOE data acquisition method adopted, whether a situation is a real event or jitter can be distinguished.

Description

technical field [0001] The invention relates to a monitoring method for an instrument and control system of a nuclear power plant, in particular to an SOE data collection method used in the field of the instrument and control system of a nuclear power plant. Background technique [0002] The instrument and control system of nuclear power plants is the "nerve center" of nuclear power plants, and is an important equipment to ensure the safe and reliable operation of nuclear power plants. [0003] With the continuous development of automatic control technology, various types of digital input signals are widely used in control systems, especially in complex nuclear power plant automatic control or monitoring systems. For nuclear power plants, whether these switching signals can correctly reflect the action state and action time of the monitoring object will affect the safety and reliability of the entire power generation system. [0004] Sequence of events record SOE is widely ...
