Anti-skid braking controller for airplane

Abstract

The invention discloses an anti-skid braking controller for an airplane, which comprises a main control device, an auxiliary control device, a power source processing unit and a dual-computer communication unit, wherein the main control device with a major anti-skid braking function is used for acquiring braking command signal and airplane wheel speed signals, and automatically regulating braking pressure according to anti-skid signals and cockpit switch selection, so that safe, stable and efficient braking of the airplane is realized while an alarm is given by means of voice or light; and the auxiliary control device with an auxiliary communication detecting function is used for realizing state monitoring of the anti-skid braking controller and components of an anti-skid braking system and realizing coordinated concurrent working with the main control device. The anti-skid braking controller for the airplane is capable of effectively improving response time and control precision of the anti-skid braking system, decreasing false alarm rate of the system, and enhancing testability, maintainability, safety and reliability of the system.

Description

technical field [0001] The invention belongs to the field of aircraft anti-skid brake control and relates to an aircraft anti-skid brake controller. Background technique [0002] With the development of society, people have higher and higher requirements on the safety, reliability, testability, maintainability and comfort of aircraft. The braking system is an important system of the aircraft. Modern aircraft basically adopt electronic or digital fly-by-wire anti-skid braking control system. Aircraft safety plays an important role. [0003] At present, because the existing controller adopts the control mode of a single-chip microprocessor (MCU), the main function of the anti-skid brake and auxiliary functions such as detection are realized in time by one MCU, which has the following disadvantages: [0004] 1. The main function of anti-skid brake and auxiliary functions such as detection often occupy CPU and memory resources, affecting the system control response time and sa...

AI Technical Summary

Problems solved by technology

[0004] 1. The main function of anti-skid brake and auxiliary functions such as detection often occupy CPU and memory resources, affecting the system control response time and sampling accuracy

[0005] 2. The detection algorithm is simple, the diagnostic ability is poor, and the false alarm rate is high

Since the entire braking process of the aircraft is only about 20 seconds, the real-time requirements are particularly high. In order to ensure the main function of anti-skid braking, detection and other functions are usually sacrificed, which affects the reliability of the system's test and diagnosis.
