Description
Technical Field
The invention relates to the field of sealing detection of media, in particular to a gas and liquid leakage detection sensor and a method.
Background
At present, the leakage detection of toxic, harmful, combustible and other gases and liquids at home and abroad basically adopts post detection (namely, the traditional detection method), namely, after the leakage of the gases and liquids reaches a certain concentration in the air, different sensors (electrochemical sensors) and other detection modes are adopted for different gases and liquids. Because of the limitation of detection principles such as sensors and the like, early warning detection and accurate positioning of leakage points cannot be achieved, and especially the leakage detection of an underground pipe network is not solved. And different sensors such as different electrochemistry and the like are adopted for different gases, so that the sensors are various and high in cost. Government interest has also been in ensuring that leak detection of such gases and liquids as toxic, hazardous, flammable, etc. is safe for both the enterprise and the public of society. If a product for solving the problems can be developed and innovated, not only can the production efficiency of enterprises be improved and the property loss of the enterprises be reduced, but also the safety, the reliability, the real-time performance and the like of the detection method can be greatly improved.

2. The traditional detection method is related to the components of the detected gas, and different traditional detection sensors are adopted for different gases; the invention is independent of the gas component to be detected, and uses the same sensor for all gases and liquids.
