Problems solved by technology

In the long-term pipeline transportation process, due to the small molecular weight of hydrogen gas, hydrogen permeation and hydrogen leakage are prone to occur.
At the same time, when the hydrogen concentration is 4%-73%, it will explode when exposed to an open flame, which brings challenges to the safe use of hydrogen. Traditional active electronic hydrogen sensors are prone to corrosion during long-term use, making it difficult to work normally, and difficult to achieve large-scale and large-scale applications.

Abstract

The invention provides a hydrogen energy storage and transportation equipment safety monitoring system and method, and the system comprises a detection pulse generation device which is used for transmitting a detection pulse; the weak grating array is coated with a hydrogen sensitive material and laid on the surface of the hydrogen energy storage and transportation equipment, the hydrogen sensitive material is used for detecting hydrogen leakage, and the weak grating array is used for receiving the detection pulse and reflecting a reflection signal; and the photoelectric detector is used for receiving the reflected signal and demodulating temperature information, hydrogen concentration information and vibration information. The safety monitoring system for the hydrogen energy storage and transportation equipment provided by the invention can monitor hydrogen leakage of a pipeline in real time, can monitor real-time signals of temperature, vibration and hydrogen concentration in safety monitoring of the hydrogen energy storage and transportation equipment, can better reflect the health condition of the equipment, monitors whether potential safety hazards of hydrogen leakage and hydrogen permeation exist or not, and improves the safety of the equipment. And potential safety hazards are eliminated in time.

Description

technical field [0001] The invention relates to the technical field of safety monitoring of hydrogen energy storage and transportation equipment, in particular to a safety monitoring system and method for hydrogen energy storage and transportation equipment. Background technique [0002] Hydrogen energy is an ideal clean energy with high energy density and no pollution. As a secondary energy, it can be directly obtained from fossil raw materials or produced by electrolysis of water. The development of the hydrogen energy economy can reduce the emission of greenhouse gases and fine particulate matter, and realize the diversification of energy sources. Countries and regions around the world have regarded hydrogen energy as the strategic development direction of new energy in the future. [0003] At present, the storage and transportation of hydrogen energy in my country is mainly in the high-pressure gas state, and the transportation of gas and hydrogen mainly includes long-tu...
