The invention discloses an integrated embedded airplane braking system which comprises anti-skid braking control software, a braking instruction sensor, a speed sensor and a servo valve. The anti-skid braking control software is integrated in an auxiliary controller of the airplane; when the airplane is braked, a pilot steps on a braking instruction sensor, the braking instruction sensor outputs a voltage signal to an auxiliary controller, a main program in the auxiliary controller calls anti-skid braking control software, the anti-skid braking control software outputs a control current to the servo valve, the servo valve outputs brake pressure to a brake main wheel, and brake control is carried out on the airplane; and meanwhile, the speed sensor senses the speed of a brake main wheel, outputs an alternating-current sinusoidal signal to the auxiliary controller and then respectively collects signals of the braking instruction sensor and the speed sensor to control the increase and decrease of the brake pressure so that the anti-skid brake function is realized. The integration level of the product is improved, the brake anti-skid function can still be normally achieved, and the weight of a brake system and the weight of the airplane are greatly reduced.
本发明公开了一种集成嵌入式飞机刹车系统,包括防滑刹车控制软件、刹车指令传感器、速度传感器、和伺服阀;防滑刹车控制软件集成在飞机的辅助控制器中;当飞机刹车时,飞行员脚踩刹车指令传感器,刹车指令传感器输出电压信号给辅助控制器,辅助控制器中主程序调用防滑刹车控制软件,防滑控制软件输出一个控制电流给伺服阀,伺服阀输出刹车压力到刹车主机轮,对飞机进行刹车控制;同时速度传感器,感应刹车主机轮的速度,并输出交流正弦信号给辅助控制器,再分别采集刹车指令传感器和速度传感器信号,控制刹车压力增减变化,实现防滑刹车功能。本发明提高了产品的集成度,仍能正常实现刹车防滑功能,大大减小了刹车系统和飞机的重量。
