Hydrogen parameter modification method, device and equipment based on fuel cell vehicle and medium

The invention discloses a hydrogen parameter modification method, device and equipment based on a fuel cell vehicle and a medium. Obtaining a to-be-modified joint description hydrogen parameter, and obtaining a parameter modification mode of the target fuel cell vehicle; establishing communication with the target fuel cell vehicle according to the parameter modification mode, and obtaining a vehicle identification code corresponding to the target fuel cell vehicle; inputting the vehicle identification code into a pre-constructed hydrogen system database vehicle model to carry out vehicle model matching, and if the vehicle model matching is carried out, obtaining a current joint description hydrogen parameter; if it is determined that the user enters the parameter modification interface, whether the to-be-modified joint description hydrogen parameter meets the hydrogen parameter allowed modification range or not is judged, if yes, the current joint description hydrogen parameter is modified through the to-be-m
