Attack angle indication dimming and carrier landing indication dimming system based on data bus control

Abstract

The invention discloses an attack angle indication dimming and carrier landing indication dimming system based on data bus control. The system comprises a left attack angle indicator, a right attack angle indicator, a carrier landing indication device, a central processing unit, a dimming driving unit, a state control driving unit, and a carrier landing indication power source driving circuit; thecentral processing unit is provided with a first CPU and a second CPU; the first CPU and the second CPU respectively receive the limit information of an airplane through two bus paths; and information sharing and information comparison are carried out between the first CPU and the second CPU through a CAN bus; the dimming driving unit is provided with a first dimming circuit and a second dimmingcircuit; the state control driving unit is provided with a first driving circuit and a second driving circuit. With the attack angle indication dimming and carrier landing indication dimming system based on data bus control of the invention adopted, dual-redundancy bus control attack angle indication and carrier landing indication are realized.

Description

technical field [0001] The invention relates to the field of dimming systems, in particular, an angle of attack indication dimming and landing indication dimming system based on data bus control. Background technique [0002] Approach angle of attack indication and landing indication are important indication tools for aircraft landing, and data bus is an important means to realize information transmission on aircraft. In order to safely and reliably realize the angle of attack indication and landing indication through bus control, and at the same time carry out stepless brightness adjustment of the angle of attack indication and day and night brightness control of the landing indication, a data bus based angle of attack indication and landing indication with dimming function is designed. Landing instruction system. When the aircraft lands, the landing commander obtains accurate information on the angle of attack of the aircraft and whether the landing hook is lowered accord...

AI Technical Summary

Problems solved by technology

[0003] Whether the system can work normally in harsh environments is directly related to the landing safety of carrier-based aircraft. The traditional angle of attack indication and landing indication system can no longer meet the needs of new carrier-based aircraft. It is urgent to design a data bus-controlled angle of attack indication and dimming and landing indication and dimming system
