Automatic control circuit applied to aircraft control surface lock

Abstract

The invention provides an automatic control circuit of an aircraft control surface lock. The automatic control circuit comprises a control surface lock power supply control circuit, a control surfacelock driving control circuit and a logic processing module, wherein the control surface lock power supply control circuit receives a wheel load signal, is connected to a motor body through the controlsurface lock driving control circuit, and sends a power on / off instruction of the control surface lock motor to the control surface lock driving control circuit according to the wheel load signal, the logic processing module receives the wheel load signal and the instruction, generates enable control or generates an enable control and control surface lock unlocking / locking instruction according to the received wheel load signal and / or instruction, and sends the enable control and control surface lock unlocking / locking instruction to the control surface lock driving control circuit, and the control surface lock driving control circuit is used for controlling the on / off of a power supply of the control surface lock motor according to the on / off power supply instruction and the enable control of the control surface lock motor, and controlling the movement direction of the motor according to the unlocking / locking instruction when the power supply of the control surface lock motor is switched on. According to the invention, intelligence and automation can be achieved.

Description

technical field [0001] The invention belongs to the automatic control and fault detection technology of an aircraft rudder lock, and relates to an automatic control circuit of an aircraft rudder lock. Background technique [0002] At present, the rudder surface lock is composed of two parts: mechanical transmission and brushed DC motor. It is used to lock the rudder surface of the aircraft after the aircraft stops to prevent damage to the rudder surface of the aircraft due to strong winds. The rudder surface lock of the aircraft includes the left Wing rudder surface lock, right aileron rudder surface lock, left elevator rudder surface lock, right elevator rudder surface lock and rudder surface lock, the structures and principles of these five rudder surface locks are the same. For the control of the rudder locks, the series control mode is adopted, that is, the positive / negative poles of the brushed DC motors of the five rudder locks are connected in series in the same circu...

Problems solved by technology

[0003] With the development of avionics, the aircraft control system is shifting towards multi-electric and all-electric. At present, the traditional method of manually controlling the aircraft rudder lock can no longer meet the requirements of automatic control, and cannot realize the automatic detection and accurate fault detection of the rudder lock. Positioning has caused great inconvenience to users and cannot realize intelligence and automation
