Multi-wheel aeroplane braking system based on self-energy-regenerative braking device and controlling method therefor

A multi-wheel aeroplane braking system based on a self-energy-regenerative braking device, the multi-wheel aeroplane braking system comprising:

• a plurality of pressure sensors and a plurality of rotating speed sensors, each pressure sensor and each rotating speed sensor arranged in a respective aeroplane wheel of a plurality of aeroplane wheels to obtain a braking pressure of the aeroplane wheel and a wheel rotating speed of the aeroplane wheel, respectively;
• a controller connected to the self-energy-regenerative braking device assembly, the plurality of pressure sensors, and the plurality of rotating speed sensors, to generate a braking instruction according to the braking pressures and the wheel rotating speeds, and to send the braking instruction to the self-energy-regenerative braking device assembly;
• a plurality of hydraulic pumps, each connected to the self-energy-regenerative braking device assembly and a correspondingly connected aeroplane wheel of the plurality of aeroplane wheels, to feed high-pressure oil to the self-energy-regenerative braking device assembly under the conversion into hydraulic energy from kinetic energy by transmission mechanisms, wherein the conversion is brought about by the motion of the aeroplane wheels when the aeroplane wheels skate on the ground;
• and
• a plurality of braking actuators, each connected to the self-energy-regenerative braking device assembly and a correspondingly connected aeroplane wheel of the plurality of aeroplane wheels,
• to receive the high-pressure oil fed by the self-energy-regenerative braking device assembly according to the braking instruction, and to brake the correspondingly connected aeroplane wheel.
