the color-changing layer is made of a color-changing nano material, and reacts with the catalyzed hydrogen to change the color of the color-changing layer.
6. The hydrogen station gas safety shield system of claim 1, wherein the hydrogen detection alarm module comprises a hydrogen detector;
the hydrogen detector is arranged at the joint of the hydrogen pipeline, detects the hydrogen concentration at a fixed frequency, uploads the hydrogen concentration, the position and time information and transmits the information to the upper computer;
and when the detected hydrogen concentration exceeds the preset concentration, performing sound and light alarm to prompt hydrogen leakage.
7. The hydrogen station gas safety shield system of claim 1, wherein the combustible gas detection alarm module comprises a plurality of combustible gas detectors;
the plurality of combustible gas detectors are distributed at each gas monitoring point in the hydrogen station, detect the concentration of combustible gas at a preset frequency and upload monitoring information including the type of gas, the concentration of gas, time and the gas monitoring points to an upper computer;
and when the detected combustible gas concentration exceeds the preset concentration, performing sound and light alarm to prompt the leakage of the combustible gas.
