Problems solved by technology

[0005] It can be seen that the monitoring functions of active aero-engines are all realized by electronic controllers, which have high requirements on the functions of electronic controllers, and the existing independent monitoring modules only aim at a single monitoring kinetic energy
In addition, no engineering research has been carried out in the field of civil aircraft, and the mastery of civil aeroengine FADEC system technology is almost blank

Embodiment Construction

[0028] Such as figure 1 As shown, in the engine FADEC system according to the present invention, all control-related functions are implemented on the EEC, and all monitoring functions to be implemented are implemented by an engine monitoring device EMU independent of the EEC. In the aircraft system, various functional modules can be included, such as vibration display (Vibration Display) module, ACARS module, fan trim balance (Fan Trim Balance) module (used for fan blade balance calculation, and the airline will take corresponding measures according to the calculation results Fault identification and troubleshooting), aircraft server (Aircraft Server) module and wireless communication (Wireless Comms.) module and so on. Among them, the measurement signal obtained by the control sensor enters into the EEC for the control of the engine, and the measurement signal obtained by the monitoring sensor (such as figure 2 As shown, for example, including vibration, speed, temperature,...

Abstract

The invention provides a distributed type aero-engine full authority digital engine control (FADEC) system which comprises a control unit and a monitoring unit, wherein the control unit and the monitoring unit are independent on hardware but are in data communication with each other through an interconnecting link. The monitoring unit is connected with a plurality of sensors for monitoring to obtain monitoring data. The control unit is connected with a plurality of sensors for controlling to obtain control data. The control data is combined with the monitoring data obtained by the control unit through the interconnecting link to carry out running state control and health monitoring control on an aero-engine. According to the distributed type aero-engine FADEC system, the monitoring function needing to be achieved in the system can be achieved on the monitoring unit independent from the control unit, and the purpose of distributed-type management of control and monitoring functions is achieved. System flexible arrangement is benefited, size, weight and function requirements of the control unit are reduced, and reliability of the system is improved.

Description

technical field [0001] The invention relates to an engine FADEC system, in particular to a civil aircraft aeroengine FADEC system capable of realizing distributed management of control and monitoring functions. Background technique [0002] Aviation engine is a kind of highly complex and repairable multi-component system, which requires repeated work for a long time under harsh conditions such as high temperature, high pressure, high speed, and high load, and is prone to failure. Any functional failure of it may cause aircraft accidents , and even lead to catastrophic consequences. According to the statistical analysis of civil aviation accidents around the world in the last 10 years, the safety situation of civil aviation is extremely severe, and the reliability requirements of civil engines in the future will become more and more stringent, which will also affect the reliability of the full authority digital electronic controller (FADEC) system Sexuality puts forward high...
