The invention relates to a gas supply system and method and a gas supply device. The gas supply system comprises gas bottles, an air compression pump, an external inflation connector, a first self-locking valve and a first pressure sensor, wherein bottle openings of the gas bottles communicate with an inflation pipeline, two inflation branches of the inflation pipeline are connected with the air compression pump and the external inflation connector respectively, the first self-locking valve and the first pressure sensor are arranged on the inflation pipeline separately, the first pressure sensor is used for monitoring pressure values of the gas bottles and feeding the pressure values back to a controller, and the controller is used for controlling the first self-locking valve to be closed when the pressure values of the gas bottles reach a preset threshold value; and the bottle openings of the gas bottles are also connected with a gas supply pipeline. According to the gas supply system and method and the gas
