The invention discloses an intelligent parking braking system for a railway wagon, relates to the technical field of railway wagon braking, and solves the technical problems that in the prior art, parking scenes and the abrasion condition of parking brake pads are not accurately considered, so that potential safety hazards exist in parking braking, and the parking effect is poor. The theoretical required torque is calculated according to the road surface gradient; calculating the wear degree of the brake pad according to the brake pad parameters; calculating an actual demand torque according to the theoretical demand torque and the wear degree of the brake pad, and then generating a brake current; the corresponding motor is adjusted according to the braking current; an alarm signal is generated according to the wear degree of the brake pad, the required torque required for braking of the truck is calculated in real time, corresponding braking torque is distributed to a plurality of braking drives of the truck in a self-adaptive mode, and the wear condition of the brake pad is dynamically calculated by considering the inconsistency of damage to the brake pad caused by the truck under different braking conditions, so that the braking effect of the truck is improved.
