The invention discloses a dual-redundancy flap control handle gear voting monitoring method, which is explained from two aspects of a flap control handle gear judgment scheme and a dual-redundancy voting scheme, and in gear judgment, a gear floating period processing mode is added, so that a control surface shaking phenomenon caused by a floating period voltage gear random state is solved; after asingle-channel result is obtained, a dual-redundancy handle gear is obtained through a cross-channel data link, voting is carried out according to a dual-redundancy strategy, a final handle gear is obtained, and the system reliability is improved. According to the method, the phenomenon that the control surface slightly shakes in the handle gear floating period is effectively avoided by increasing the processing strategy of the handle gear floating period; a handle gear voting strategy based on a dual-redundancy system is designed in a targeted mode, it is ensured that a flap control system can obtain stable and reliable control handle gears, and the control handle gears are provided for a control rate to be used for controlling a control surface. The method has high transportability in design, and the stability and reliability of the system can be improved strategically.
Description
technical field [0001] The invention relates to but not limited to the field of design of flap control computers of flight control systems, and discloses a dual-redundancy flap joystick shift voting monitoring method. Background technique [0002] In the flight control system, the flap control computer performs closed-loop control of the flaps through the flap control handle sensor and flap position sensor information, and reports the flap handle and flap position information to the pilot. Based on the above discussion, whether the flap control system can correctly obtain the gear position information of the joystick sensor has an important impact on the safety of the flight control system. [0003] At present, in the general way of obtaining the gear information of the handle sensor, there is often little attention to the intermediate state of the gear change. However, the information of each gear of the sensor usually corresponds to a discontinuous voltage signal in the fo...
