Abstract

The present invention proposes a kind of aircraft cockpit indicator light driving device based on multilevel bus, wherein: the system control board 30 is provided with aircraft cockpit indicator light; 20 is connected to the electromechanical system network node 40; the lamp driving control device 20 and the system control board 30 are connected through the second-level bus. The device sets the indicator light drive device as the core of the indicator light drive system, and obtains the status and data information of each electromechanical subsystem through the multi-level electromechanical bus, thereby realizing the drive control management of the indicator lights on the digital system control board of the cockpit electromechanical system. This system is applied to drive the switch indicator light on the control board of the cockpit digital system. Using the bus network structure can not only simplify the electrical characteristics of the light drive management system, reduce the type and quantity of electrical interfaces, reduce complexity, reduce system weight, but also improve The reliability of the aircraft cockpit light driving system is improved.

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
