| description | The invention relates to a vacuum degree early warning and alarming method, in particular to a liquid hydrogen transportation equipment vacuum degree early warning and alarming method, which comprises the following steps: firstly, constructing a correlation model of in-tank pressure and storage and transportation time under different interlayer vacuum degrees; acquiring a current in-tank pressure change value; and finally, the obtained in-tank pressure change value is input into the correlation model, the vacuum degree about to exceed the safety threshold range is obtained, and meanwhile early warning is conducted. Or the vacuum degree exceeding the threshold value range is obtained, and an alarm is given to the transportation system exceeding the threshold value range. The method has the advantages of being convenient to monitor, high in sensitivity and good in effect, the vacuum degree change of the heat insulation layer can be detected in real time through the vacuum early warning method so that the good h |
