Expert system and method for judging emergency state of nuclear power plant

Abstract

The invention discloses an expert system and method for judging an emergency state of a nuclear power plant. The expert system comprises a real-time monitoring data module, a manual supplemental information module, a database system, a human-computer interface, and a knowledge base system connected with the human-computer interface, wherein the real-time monitoring data module is connected with an industrial data network of the nuclear power plant and an online environment radiation monitoring system, and reads running parameters and environment radiation monitoring data of units of the nuclear power plant in real time; the manual information supplementation module is used for selecting an emergency action level or inputting an emergency action level event; the database system is used for storing real-time monitoring data, manual supplemental information data and historical emergency state judgment data; and the human-computer interface is connected with the database system. Compared with the prior art, the expert system and method has the advantages that knowledge construction and inference basis of emergency state judgment are carried out in combination with an emergency plan IC&EAL matrix table established by the nuclear power plant based on expert knowledge and experience, the expert system for judging the emergency state of the nuclear power plant is realized, and reliable support is provided for emergency decision-making.

Description

technical field [0001] The invention belongs to the field of artificial intelligence, and more specifically, the invention relates to an expert system and method for judging an emergency state of a nuclear power plant. Background technique [0002] Artificial intelligence is a branch of computer science, the discipline that studies machine intelligence. Expert systems have been developed as a research tool since the 1960s, as a specific part of artificial intelligence. CLIPS (CLanguage Integrated Production System, C Language Integrated Production System) is a general-purpose expert system tool, which was first used in the field of aerospace control in the United States and has high reliability. It has now been extended to medical, electric power, machinery manufacturing and other industries . In foreign countries, CLIPS has been applied to the operation and management of nuclear power plants. Relatively speaking, the research and application of CLIPS in China started rela...

Problems solved by technology

[0012] (1) Only rely on the pre-established EAL for auxiliary judgment of emergency state. For the judgment of multiple events of the same level with different causes, it still needs to go through the operation duty chief and emergency command decision-making. This auxiliary judgment system cannot make full use of the expertise of experts in this field. Knowledge and experience, without imitating the thinking process of human experts in judging the emergency state at the time of emergency;

[0013] (2) The types of manual data collection involved in EAL are relatively complicated, and if they are input one by one, it will inevitably affect the efficiency of system execution;

[0014] (3) Directly using high-level language to program EAL for logical judgment is not conducive to the expansion of the system
