Intelligent hydrogen leakage detecting system based on wireless sensing network

Abstract

The invention discloses a hydrogen leakage intelligent detection system based on a wireless sensing network, which comprises a hydrogen sensitive probe module, a wireless communication network module and a signal analysis processing module. The hydrogen sensitive probe module is connected with the signal analysis processing module through the wireless communication network module, after completing calibration, the hydrogen sensitive probe module makes filtering and modulation to a data signal, the wireless communication network module acquires and converses the analog data signal, makes processing according to the calibration result, makes judgment according to the processing result, transmits the processing result to a concourse center in a wireless way, and then transmits to a information analysis processing module. The hydrogen leakage intelligent detection system based on a wireless sensing network has the advantages of small size, low cost, convenient installation, strong anti-interference capability, quick response speed, and high safety.

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...

Problems solved by technology

[0003] At this stage, domestic hydrogen-sensing detection signal transmission is based on the bus transmission method. Although this method has the advantage of high information reliability, due to the relatively large environmental range of hydrogen storage and transmission and the places where it is easy to leak This has caused difficulties in the wiring of the wired communication method, and the wired-based method has great difficulties in system expansion, and in many cases it is even impossible
