Passenger cabin core system for civil wide-body airliner

Abstract

The invention discloses a passenger cabin core system for a civil wide-body airliner. The system comprises an external crosslinking system and an internal core system; the external crosslinking systemis used for being crosslinked with a system outside the passenger cabin core system for the civil wide-body airliner for information and data interaction; the internal core system comprises a level-Anetwork and a level-B network; the level-A network is a public platform for the passenger cabin core system, and can be expanded to a public platform of the passenger cabin system; the level-A network is used for unified access to external interfaces to achieve external security protection; the level-B network is used for completing broadcasting and interphone functions of a passenger cabin, completing application control functions relevant to passengers, achieving light control over the whole cabin and achieving the function of electronic portholes; while the functions of the passenger cabincore system are achieved, platform unification, zone control and passenger cabin security protection are comprehensively considered at the same time, and the passenger cabin core system is easily integrated with the crosslinking system, and has high expandability.

Description

technical field [0001] The invention relates to the field of cabin core system design, in particular to a cabin core system of a civil wide-body passenger aircraft. Background technique [0002] The Cabin Core System (CCS) is the data cross-linking center of the cabin system. It has the functions of comprehensive cabin management and control, cabin broadcast and intercom, passenger call, data forwarding and data communication inside and outside the cabin system, and provides passengers with no-smoking, fastening security. With and other instructions, providing a centralized maintenance platform. Compared with in-flight entertainment and external communication systems, the cabin core system is a must-install system for the aircraft and an important part of the cabin system. [0003] At present, my country is vigorously developing civil aviation construction. The single-aisle passenger aircraft C919 completed its maiden flight on May 5, 2017, and the Sino-Russian long-range w...

AI Technical Summary

Problems solved by technology

[0008] 1. The cabin system has not achieved unified access. For example, the audio control panel ACP (a device in the cockpit, used to initiate a call with the cabin, broadcast or call to the ground) is directly connected to the audio control unit ACU (ACU and regional audio The ring network composed of units ZAU realizes cabin broadcasting and intercom functions. ACU is the control device of the entire ring network. ZAU mainly realizes digital-to-analog conversion. FAH is a telephone and Speaker is a loudspeaker); the information system gateway and CIU (cabin interface unit, It can be understood as the server of the core system of the cabin, and the centralized location of computing resources) to connect;

[0009] 2. The cabin network and equipment are divided into multiple areas and controlled separately. Functional applications across subsystems cannot perform unified resource allocation and signal synchronization. Cross-subsystem application control management logic is relatively complex

[0010] 3. Low upgradeability and scalability

[0011] 4. Since the network scale of each subsystem on the C919 is small, the network performance problem has not been confirmed yet

This will cause problems such as failure to drive or poor network performance.
