A hydrogen supply monitoring system is characterized by comprising a vehicle, a background server and a mobile terminal, wherein the vehicle comprises a vehicle-mounted hydrogen supply system and the vehicle-mounted hydrogen supply control system as claimed in any one of claims 1 to 7, and the background server is respectively connected with a hydrogen supply controller and the mobile terminal in the vehicle-mounted hydrogen supply control system;
the hydrogen supply controller is used for sending hydrogen supply data to the background server, wherein the hydrogen supply data comprise a collision strength value, at least one hydrogen supply environment parameter, vehicle running data and running environment data;
the background server is used for determining whether the vehicle has a safety risk according to the hydrogen supply data and sending risk early warning information to the mobile terminal when the vehicle has the safety risk;
the mobile terminal is used for outputting first prompt information according to the risk early warning information, and the first prompt information is used for reminding a user that the vehicle-mounted hydrogen supply system has a safety risk.
9. The on-board hydrogen supply control system according to claim 8,
the background server is further used for determining the remaining life of each part in the vehicle-mounted hydrogen supply system according to the hydrogen supply data, and sending life early warning information to the mobile terminal when the remaining life of the first target part is shorter than a preset time length;
and the mobile terminal is used for outputting second prompt information according to the service life early warning information, and the second prompt information is used for reminding a user of replacing the first target part.
10. The on-vehicle hydrogen supply control system according to claim 8 or 9,
the background server is further used for determining whether each part in the vehicle-mounted hydrogen supply system needs to be maintained according to the hydrogen supply data, and sending maintenance reminding information to the mobile terminal when a second target part needs to be maintained;
and the mobile terminal is used for outputting third prompt information according to the maintenance prompt information, and the third prompt information is used for prompting a user to maintain the second target part.
