Abstract

The application belongs to the field of aero-engine onboard sensor signal processing, in particular to a dual-redundancy sensor signal voting method based on fault integration. The method includes: Step 1: Obtain the measured value of the dual-redundancy sensor signal, perform extreme value fault judgment and cross fault judgment on the measured value of the double-redundant sensor signal, and obtain the extreme value judgment result and the cross judgment result; Step 2: Obtain the measurement status of the dual-redundancy sensor signal, and obtain signal status information according to the measurement status of the dual-redundancy sensor signal and the extreme value judgment result; step 3: perform fault integration on the signal status information to obtain the fault integration Result; Step 4: Vote according to the cross judgment result, the signal state information, and the fault integration result to obtain a voting result. The application can avoid the unstable control of the engine caused by the parameter selection change, and can reduce the maintenance cost.

Description

technical field [0001] The application belongs to the field of aero-engine airborne sensor signal processing, and particularly relates to a dual redundancy sensor signal voting method based on fault integration. Background technique [0002] In the aero-engine digital electronic control system, the state parameters of each section of the engine are reflected by sensors, and converted into electrical signals, which are provided to the digital electronic controller to control and monitor the engine. Generally, the on-board sensors of the engine for control are in the form of dual redundancy sensors, which can ensure that when there is a problem with one redundancy of the sensor, it can be replaced by other redundancy, which improves the reliability of the system. However, it also brings corresponding problems. When the measurement results of different margins are different or the sensor is faulty, how to select the appropriate measurement data to control the engine is crucial ...
