Airplane brake system and static brake protection control method

Disclosed are an airplane brake system and a static brake protection control method. When a simulated airplane speed is lower than a preset static brake control secure threshold, an antiskid control box enables a static brake protection relay to be connected, and otherwise, the antiskid control box enables the static brake protection relay to be disconnected; the static brake state of an airplane is determined according to on-off signals of the static brake protection relay; aerial/ground states of the airplane are determined through a first landing switch and a second landing switch; and a static brake subsystem achieves the function of airplane static brake protection through the special control logic according to the speed state and the aerial/ground states of the airplane. The static brake function and the ground connection protection function of the airplane are separated thoroughly, the problem that the static brake subsystem outputs the static brake pressure under the condition that the ground connecti
