Aircraft cockpit indicating lamp driving device based on multistage bus

Abstract

The invention provides an aircraft cockpit indicating lamp driving device based on a multistage bus. An aircraft cockpit indicating lamp is arranged on a system control panel 30; an electromechanicalbus controller 10 is connected with a lamp driving control device 20 and an electromechanical system network node 40 through a first-stage bus. The lamp driving control device 20 is connected with thesystem control panel 30 through a second-stage bus. The device is provided with the indicating lamp driving device as the core of the indicating lamp driving system and obtains the state and data information of each electromechanical subsystem through the multi-stage electromechanical bus, thereby achieving the driving control management of the indicating lamp on the cockpit electromechanical system digital system control panel. The system is applied to switch indicating lamp driving on the digital system control panel of the cockpit, and the electrical characteristics of the lamp driving management system can be simplified by using the bus network framework, the types and the number of electrical interfaces are reduced, the complexity is reduced, the weight of the system is reduced, andthe reliability of the aircraft cockpit lamp driving system is also improved.

Description

technical field [0001] The invention relates to the technical field of electromechanical integrated management technology, in particular to an aircraft cockpit indicator light driving device based on a multi-level bus. Background technique [0002] The control panel system of the electromechanical system in the cockpit of a modern aircraft usually includes hydraulic pressure, landing gear, brakes, turning, fuel, environmental control, anti-icing, liquid cooling, power supply, lighting, and power system control panels. Different kinds of indicator lights are used to remind the system working status. The traditional indicator light control device mainly uses the hard-wire interface to complete the switch status collection of each electromechanical system control board, and drives the indicator lights on the control board through the hard wire, and completes the driving and control of the indicator lights on the electromechanical system control board in the aircraft cockpit in ...

AI Technical Summary

Problems solved by technology

Considering the complexity of the electromechanical systems of modern aircraft, there are many signals in each electromechanical system. The traditional hard-wire acquisition and driving method not only increases the complexity of cross-linking between devices, but also increases the weight of cables, which also leads to the reliability of the system. Therefore, the design of the modern aircraft cockpit indicator light system requires comprehensive consideration of the complexity and reliability of the system architecture in order to improve the reliability of the entire electromechanical integrated management system
