Description

technical field

[0001] The invention mainly relates to the field of hydrogen energy leakage detection, in particular to a hydrogen leakage intelligent detection system based on a wireless sensor network. Background technique

[0002] In the next few decades, hydrogen, as an emerging energy carrier, will play an important role in the world's energy field and is widely used in aerospace power, transportation, chemical production and other fields. However, hydrogen is a very penetrating gas and is particularly prone to leakage. Scientists estimate that the leakage of hydrogen in the whole process of production, storage, transportation and distribution will reach 10-20% of the total amount of hydrogen. Due to the large range of combustion volume ratio of hydrogen / air mixture, low ignition energy, and easy explosion, with the development of hydrogen projects and the development of hydrogen economy, the problem of hydrogen leakage detection will inevitably receive more and more a...
