On the basis of the technical scheme, the invention can be further improved as follows.
Further, a first flow sensor and a first flow regulating valve are further arranged on the additional air pipeline, and the first flow sensor is used for collecting a first gas flow signal in the additional air pipeline and sending the first gas flow signal to the control module; the control module controls the opening of the first flow regulating valve according to the inflation pressure change rate and the first gas flow signal, so that the inflation pressure change rate of the additional gas pipeline is within a preset safety range, and the gas flow of the additional gas pipeline is within an inflation flow safety range.
