Problems solved by technology

[0004] (1) When the main control unit in the main control channel fails, this channel cannot work normally, and can only switch to the backup channel to work, which will reduce the safety and reliability of the entire controller;
[0005] (2) When the logical processing unit in the main control channel fails, this channel cannot work normally, and can only switch to the backup channel to work, which will reduce the safety and reliability of the entire controller;
[0006] (3) When some circuits in a channel fail, the entire channel will be ineffective, causing a great waste of circuit resources that can still work normally in this channel

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0037] figure 1 is a schematic diagram showing the architecture of a conventional engine electronic controller 100 . The electronic controller 100 adopts a dual-channel architecture, and each control channel includes identical functional units. Specifically, the control channel A may include a signal conditioning unit 110a, a main control unit 120a, a logic processing unit 130a, and a driving processing unit 140a. The control channel B may include a signal conditioning unit 110b, a main control unit 120b, a logic processing unit 130b, and a driving processing unit 140b.

[0038] Signal conditioning units 110a, 110b can receive input signals...

Abstract

The invention provides an engine electronic controller which comprises a plurality of control channels. Each control channel comprises a signal conditioning unit, a main control unit, a logical processing unit and a driving unit which are mutually coupled in a communication manner, wherein the main control units of the control channels are coupled in a communication manner, and the logical processing units of the control channels are coupled in a communication manner. Each control channel further comprises a reconstruction processing unit which is coupled to the units of the control channel in a communication manner, wherein the reconstruction unit executes a main control task of the main control unit when the main control unit of the located control channel breaks down.

Description

technical field [0001] The invention relates to the fields of engine digital electronic control and embedded systems, in particular to a redundant engine electronic controller. Background technique [0002] With the continuous improvement of aircraft performance, higher requirements are put forward for the performance of aero-engines, which leads to the continuous increase of control variables and control functions of the engine control system, which makes the control system more and more complex. The core engine electronic controller How to ensure the safe and reliable operation of the engine electronic controller and how to establish a highly fault-tolerant and reconfigurable mechanism for electronic control are important measures to solve its safe and reliable work. [0003] At present, the electronic controller of the engine adopts a dual-channel structure, and a single channel can complete the control task of the entire engine. Backup channel, when the main control cha...
