Image detection system for analyzing river ice flower characteristics and ice cover thickness

Abstract

The invention discloses an image detection system for analyzing river ice flower characteristics and ice cover thickness. The image detection system is suitable for analyzing the river ice flower characteristics and the ice cover thickness. The invention provides an image detection system which has a high-precision and real-time online function and can be used for continuously measuring the ice flower density, the particle size and the ice cover profile. According to the technical scheme, the system comprises a cylindrical container, an image acquisition module, a rotary moving module, a control module, a heating module and a wireless transmission module. The image acquisition module, the rotary moving module, the heating module and the wireless transmission module are both connected withthe control module. The cylindrical container is arranged in an ice hole in a detected place; wherein the heating module is adjacently arranged around the cylindrical container, the image acquisitionmodule ascends, descends and rotates in the cylindrical container along with the rotary moving module to acquire ice hole images around the cylindrical container, and the wireless transmission moduleis used for wirelessly transmitting the ice hole images to the monitoring center and receiving instructions from the monitoring center.

Description

technical field [0001] The invention relates to an image detection system for analyzing the characteristics of ice flakes and the thickness of ice sheets, in particular to an image detection system for analyzing the characteristics of ice flakes in a river and the thickness of ice sheets. Background technique [0002] Rivers in high latitude regions of my country will freeze in winter, forming closed ice sheets on the river course. Due to various reasons, such as the continuous drainage of coastal power plants into the river, the river section will not be able to freeze, and the exposed water surface will directly exchange heat with the cold air, making the water temperature always below 0°C in a supercooled state, resulting in a large amount of water Inner ice, that is, ice flowers. The ice flakes flow with the water flow, slow down at some river bends, accumulate and adhere to the lower layer of the ice sheet, prompt the ice sheet to thicken rapidly, block the river chann...

AI Technical Summary

Problems solved by technology

[0003] At present, the detection methods of ice sheet thickness in the river can be divided into contact type and non-contact type. Common contact measurement methods such as manual drilling and thermal resistance wire detection methods are the most reliable, but their automation is low, labor-intensive, and impossible. Realize online detection; non-contact measurement methods such as remote sensing and radar can realize a large-scale ice thickness survey, but the disadvantages are low precision, high cost, and cannot reflect the changing process inside the ice sheet

For the detection of the characteristics of ice flakes at the bottom of the ice sheet, there is currently only the method of manual on-site observation, and the ice flake detection technology with high precision and real-time online functions is still blank at home and abroad.
