According to the anti-skid protection control method for the airplane wheel braking system, anti-skid protection control logic is optimized, and when a bus wheel load signal is invalid, a braking controller judges whether braking is implemented or not through a hard wire wheel load; the brake controller judges whether the airplane wheel is fully started or not according to the airplane wheel reference speed in real time, whether the airplane wheel is started or not is more accurately expressed, misjudgment caused by airplane wheel jumping is prevented, and the system safety is improved. When the left wheel load signal and the right wheel load signal are inconsistent, judgment is carried out through the airspeed signal, the situation that the braking function is lost due to wheel load jumping during low-speed sliding is avoided, and the usability of the system is improved by 12%. The anti-skid protection is improved through the brake controller, and the situation that the brake function is completely lost due to wheel load error indication and jumping during low-speed sliding is effectively avoided; bus signal validity judgment is provided, and the availability of a brake system is improved; and airplane wheel speed effectiveness judgment is introduced, so that the accuracy of anti-skid protection is improved, and the availability of a brake system is effectively improved by 12%.

    一种飞机机轮刹车系统防滑保护控制方法,优化防滑保护控制逻辑,当总线轮载信号无效时,刹车控制器通过硬线轮载判断是否实施刹车;刹车控制器实时通过机轮参考速度判断机轮是否充分起转,更准确的表达机轮是否起转,防止了机轮跳变造成的误判断,提高了系统安全性。当左、右轮载信号不一致时,通过空速信号进行判断,避免低速滑行时由于轮载跳变致使丧失刹车功能,提升了系统的可用性12%。本发明通过刹车控制器即完成防滑保护的提升,有效避免了低速滑行时轮载误指示以及跳变导致的完全丧失刹车功能;提供了总线信号有效性的判断,提升了刹车系统的可用性;引入了机轮速度有效性判断,提高了防滑保护的准确性,有效提升了刹车系统的可用性12%。
