Abstract

The invention belongs to the technical field of civil aircraft WAIC network system architecture design, and particularly relates to an aircraft WAIC network system architecture. Through the fusion design of an AFDX network and a WAIC network, the data communication of the same aircraft in four different application scenarios can be ensured not to interfere with each other, the wireless nodes in the same application scenario can perform time-sharing transmission, the reliability of message transmission is ensured under the condition of ensuring controllable delay, and the use requirement of the WAIC network communication technology on civil aircrafts is further met.

Description

technical field [0001] The invention belongs to the technical field of civil aircraft WAIC network system architecture design, and in particular relates to an aircraft WAIC network system architecture. Background technique [0002] The development of avionics technology has greatly improved the safety and automation level of civil airliners. Information is exchanged between subsystems through the aeronautical data bus. Currently, the weight of aircraft cables and related connecting devices accounts for 2% to 5% of the total weight of the aircraft. Taking the Airbus A380-800 as an example, the cable length of the whole aircraft is about 470km, and the weight of the cable is about 5.7 tons. 30% of the cables (about 1.7 tons) can be replaced by wireless communication. The use of a large number of communication cables brings additional costs to the manufacture and operation and maintenance of aircraft. In order to further reduce weight, reduce cost, and improve the safety and r...
