Description

technical field [0001] The invention relates to the field of leakage detection, in particular to an intelligent detection system for leakage of LNG stations based on multi-source images and a detection method thereof. Background technique [0002] With the promotion of natural gas, natural gas has been widely used as an energy source in existing industrial production to meet heating, smelting, baking and other needs. The use of natural gas is mostly transported by gas pipeline installation, and the natural gas delivery volume is controlled through gas valves. Natural gas leaks are prone to occur in areas where gas pipelines are connected, gas valves, etc., so doing a good job in leak detection of natural gas pipelines is the key to ensuring safe industrial production. At present, using gas pipelines to transport natural gas is the only way to transport large quantities of natural gas on land, so the gas safety management for the gas control system is very important.

Problems solved by technology

At present, there have been detection methods that apply infrared temperature measurement technology to tank leak detection, but there are still defects such as the inability to accurately locate the real-time location of the leak point.

In order to accurately locate the leak location, a detection method that uses multiple auxiliary light sources to achieve accurate positioning has also appeared in the prior art. However, this method will cause abnormal temperature around the tank during detection, resulting in unsafe factors
