The invention discloses an electric pneumatic braking system and device for a power-concentrated motor train unit and a control method. The electric pneumatic braking system comprises a switching pneumatic control valve; the main and auxiliary valves are communicated with a train pipe, an auxiliary air cylinder and an air inlet b of the switching pneumatic control valve; the electromagnetic switching valve is communicated with the pilot port a of the switching pneumatic control valve, the main and auxiliary valve and the auxiliary air cylinder; the pressure regulating valve group is communicated with the air inlet c of the switching pneumatic control valve, the main and auxiliary valve and the auxiliary air cylinder; the relay valve is communicated with the brake cylinder between the main and auxiliary valves and the auxiliary air cylinder; the pneumatic control shutoff valve is communicated with the train pipe and a second air outlet of the main and auxiliary valve; and the two-way valve is communicated with an air outlet g of the pneumatic control intercepting valve, an air outlet d of the switching pneumatic control valve and a pre-control pressure input port of the relay valve. Compared with the prior art, the electric pneumatic brake control system has the beneficial effects that electric pneumatic brake control and automatic air brake control can be quickly switched according to conditions, and emergency brake control is considered, so that the safety and reliability of the whole brake control are ensured.
