Blockage net in-place monitoring alarm system based on image identification

Abstract

The invention provides a blockage net in-place monitoring alarm system based on image identification, belongs to the technical field of image identification monitoring and is used for the monitoring alarm work of an in-place state of a blockage net at a water intake of a nuclear power plant. The blockage net in-place monitoring alarm system provided by the invention comprises two parts of an outdoor image monitoring system and an indoor image identification alarm system. The outdoor image monitoring system takes charge of monitoring the in-place state of the blockage net. The indoor image identification alarm system identifies a monitored video image, optimizes an image identification algorithm, makes a blockage net failure discrimination standard algorithm, can identify the image to judgepositions and a number of orange buoys on the blockage net so as to determine a working state of the blockage net, and can send out an alarm signal by an alarm in a case of determining danger. The invention establishes the blockage net in-place alarm system based on image monitoring and image identification, which can discriminate the working state of the blockage net by identifying the positionsand the number of the buoys and can send out the alarm signal in emergency, so that a worker timely takes emergency treatment.

Description

technical field [0001] The invention belongs to the technical field of image recognition and monitoring, and in particular relates to the monitoring and alarming work of the block at the water intake of a nuclear power plant. Background technique [0002] Most of the nuclear power plant reactors use pressurized water reactors, and the circulating cooling water system of the reactors in the station and the cooling water of important equipment all use the water intake as the water source. But in summer, the sea water temperature is higher, and sea creatures multiply in large numbers. In the process of pumping cooling water, a large number of marine organisms will enter the water intake pump room through the water intake channel, block the drum filter and cause a pressure difference alarm, which in turn leads to shutdown and reactor shutdown, resulting in huge economic losses. For this reason, the nuclear power plant arranges a trash net at the front end of the water intake ch...

AI Technical Summary

Problems solved by technology

Under the joint influence of net attachments, wind waves and tides, etc., it is easy to cause the main rope to break and the main net to crack due to tension overload, so that a large number of aquatic organisms and seaweed and other debris enter the water intake, affecting the safety of nuclear power plants Operations cause huge economic losses
