Embodiment Construction
[0050] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.
[0051] Such as figure 1 Shown is a schematic diagram of the working principle of the dual side sticks of an existing civil aviation passenger aircraft. The existing civil aviation passenger aircraft adopts a forward channel with double passive side sticks, which may transmit superimposed control signals to the flight control system to output superimposed Manipulate results. The embodiment of the present invention proposes a solution to the ground rubbing problem in the take-off and landing phases of a large-scale civil aviation aircraft with side stick control due to human errors caused by...

The embodiment of the invention discloses a double-side-rod superposition protection control and alarm system. The system comprises a signal filtering module, a side rod priority logic module, a weighting coefficient and threshold module and an alarm module, wherein the signal filtering module receives control signals generated by a PF side rod and a PM side rod for signal filtering, and transmitsnon-zero effective control signals to the weighting coefficient and threshold module; the side rod priority logic module allocates a control authority to the PF side rod and the PM side rod accordingto an input signal generated by pressing a priority button, and outputs a priority signal; the weighting coefficient and threshold module sets a weighting coefficient according to a side priority signal, and generates an instruction signal used for being transmitted to a flight control computer according to the control signals and a weighting coefficient; and the alarm module determines whether to perform double-side-rod superposition alarm and / or near-ground touching ground alarm or not according to input signals and flight attitude information provided by an aircraft sensor. According to the embodiment of the invention, a problem that an aircraft touches the ground due to human errors caused by side rod superposition in existing civil aviation is solved, and flight safety of a large commercial civil aviation aircraft is improved.
Description
Technical field [0001] This application relates to, but is not limited to, the technical field of civil aviation control systems, and is the application of automatic control technology in the civil aviation field, especially a double-side rod superimposed protection control and warning system. Background technique [0002] Civil aviation aircraft adopt manual control modes during take-off and landing, and the superimposition of side sticks mainly occurs in the near-ground leveling phase. Because the passive side stick lacks a reverse drive device, it is very easy to cause man-machine information blockage and errors in information interaction between the main and co-pilots, which leads to the superimposition of the instantaneous input control amount and excessive errors. Excessive errors in the control levers will cause excessive attitude angles of the aircraft. In the case of close to the ground, the aircraft's tail, nose, and wing tips may scratch the ground. The "superimposed ...
