Abstract

The invention discloses a water level measuring system based on thermal imaging and a measuring method thereof. The water level measuring system comprises a power supply system, a water gauge, an infrared imaging system and a remote monitoring system; the power supply system is installed on a river revetment; the water level gauge is fixedly mounted in a river slope; the infrared imaging system ismounted on a river channel revetment on the opposite side of the water level gauge; the power supply system is electrically connected with the water gauge; and the remote monitoring system is electrically connected with the infrared imaging system. The system can continuously and automatically detect the water level for a long time, and has the advantages of loose environmental requirements, lowinstallation cost, good stability, simple maintenance and the like. The system can be applied to scenes with water level measurement requirements, such as rivers, reservoirs, lakes, rivers, hydropowerstations and irrigation district drainage basins. By means of the system, the water level of a riverway or a canal can be accurately measured, errors are fixed, and the errors cannot be changed alongwith range expansion.

Description

technical field [0001] The invention relates to the technical field of water level measurement, in particular to a thermal imaging-based water level measurement system and a measurement method thereof. Background technique [0002] my country has a vast territory and many water areas. When severe weather occurs, if accurate and effective water level monitoring is not carried out in time, the water level will exceed the warning line, which will cause serious waterlogging disasters. Therefore, it is necessary to detect the water level of the river or dam in real time, and when the water level exceeds the warning level, it is necessary to open the gate to release the water. [0003] There are many methods for water level measurement in my country's water conservancy construction, such as: slope paint water gauge, ceramic tile embedded water gauge, stainless steel water gauge, water level measurement well, etc., all because the durability of use cannot be guaranteed or due to wa...
