The invention discloses an airplane brake pressure feedback adjusting system which comprises a main control device, an airplane wheel speed sensor, an airplane wheel torque sensor, an electronic anti-skid control box and an electro-hydraulic servo valve. The main control device comprises a main microprocessor, a brake instruction conditioning unit, a wheel speed signal conditioning unit, a cockpitswitching signal conditioning unit, a control signal output conditioning unit and an alarm conditioning unit. And the brake instruction conditioning unit, the wheel speed signal conditioning unit, the cockpit switching signal conditioning unit and the power supply processing unit are connected with the main microprocessor. The system has the advantages that a high-safety fault processing strategyis adopted, the braking capacity of the airplane is guaranteed, and therefore the taking-off and landing braking safety of the airplane is further improved. When any electrical element in the systemhas a single redundancy fault, the standby channel can be switched to work, and the braking capacity of the system is not affected.
本发明公开了一种飞机刹车压力反馈调节系统,包括主控装置、机轮速度传感器、机轮力矩传感器、电子防滑控制盒和电液伺服阀;所述主控装置包括主微处理器、刹车指令调理单元、轮速信号调理单元、座舱开关信号调理单元、控制信号输出调理单元以及告警调理单元,所述刹车指令调理单元、轮速信号调理单元、座舱开关信号调理单元、电源处理单元与所述主微处理器连接。优点在于:本发明采用了高安全性的故障处理策略,保证了飞机的刹车能力,从而进一步提高了飞机起降制动的安全性。当系统中任一电气元件出现单余度故障,均可以切换到备用通道工作,不影响系统刹车能力。
