The invention provides a tank pressurization controller. The tank pressurization controller is connected with a main valve, a backup valve and a tank, the main valve and the backup valve are connected in parallel, and the tank pressurization controller comprises a main pressurization branch, a backup pressurization branch and a pressure switch; the main pressurization branch is connected with the main valve through the normally closed contact of a relay, and is used for supplying power for the main valve in a conduction state; the backup pressurization branch is connected with the backup valve through the normally open contact of the relay, and is used for supplying power for the backup valve in a conduction state; the relay is used for conducting the main pressurization branch or the backup pressurization branch; and the pressure switch is connected with the relay and the tank, and is used for powering off the relay when the pressure of a gas in the tank is always in a preset working pressure range in order to make the relay conduct the main pressurization branch, and powering on the relay when the pressure of the gas in the tank exceeds the preset working pressure range in order to make the relay conduct the backup pressurization branch.
