Nuclear power plant high-risk operation intelligent monitoring system and method

Abstract

The invention discloses an intelligent monitoring system and method for high-risk operation of a nuclear power plant. The intelligent monitoring system comprises a monitoring center module, a target detection module, a character recognition module, a voice recognition module, a spatial information module and a human-computer interaction module. The method comprises the following steps: a confirmation stage before operation; an operation monitoring stage; end of operation phase. The beneficial effects of the invention are that: the method is suitable for industrial production; the target detection module identifies the equipment category, the equipment state, the equipment position and the human hand position in real time; the character recognition module recognizes codes corresponding to the equipment in real time, the monitoring center module obtains the specific equipment state in real time according to the information and judges the operation process according to the operation rules, equipment coding and equipment state confirmation before operation are completed, and feedback or warning is conducted through the voice synthesis module or the human-computer interaction interface.

Description

technical field [0001] The invention belongs to a nuclear power plant risk monitoring method, in particular to an intelligent monitoring system and method for high-risk operation of a nuclear power plant. Background technique [0002] Safe production is an eternal topic in the industrial field, especially in the field of nuclear power, where nuclear safety always comes first. The reactors of each nuclear power plant involve a large number of control operations, including but not limited to various tests, in various operating states such as cold shutdown, hot shutdown, criticality, hot standby, and power operation, and during each state transition, and these operations Most of them have high execution risks. If the operation is not done properly, it will cause transient transient of the unit, and directly cause reactor shutdown or equipment damage, which not only directly affects the economic benefits of the power plant, but also seriously threatens nuclear safety.

AI Technical Summary

Problems solved by technology

However, the guardianship at the present stage still has obvious shortcomings: on the one hand, the labor cost of guardianship consumption is extremely high

High-risk operations often require a professional engineer or operator who has worked for at least five years to act as a guardian. Most power plants give priority to using high-level personnel such as duty chiefs, section chiefs, and squad leaders. Considering the large number of operations in nuclear power plants , high-frequency, and long-term attributes, this is a huge labor cost; on the other hand, the monitoring effect cannot be guaranteed to be stable due to the inherent limitations of humans

Monitoring consumes a lot of energy of the guardian, especially in the environment of on-site noise and high temperature, the effect of monitoring is easily affected
