Abstract

The invention provides a hydrogen leakage traceability system based on multi-source information coupling, and relates to the technical field of hydrogen refueling station safety management. In the hydrogen leakage traceability system provided by the invention, the first detection unit is used for collecting the pressure, flow and temperature of hydrogen at the gas inlet and the gas outlet of the hydrogen-contacting equipment, and the second detection unit is used for collecting the pressure, flow and temperature of hydrogen at the gas inlet and the gas outlet of each hydrogen refueling station pipeline; the first detection unit and the second detection unit transmit collected data to the control module, the processing unit is used for comparison based on a constructed hydrogen environment mechanism model, and information, corresponding to abnormal data existing in a comparison result, of the first detection unit or the second detection unit is transmitted to a displayer of a user. Therefore, the user can conveniently check the abnormal data in the hydrogen refueling station according to the corresponding information, and the speed of judging the hydrogen leakage point in the hydrogen refueling station by the user is improved.
