The invention relates to the field of overall design of flight control systems, in particular to a monitoring voting method of double redundancy radio altimeters. The monitoring voting method comprises steps as follows: step one, states of two channel radio altimeters are judged, the step two is implemented when the two radio altimeters are normal, when one radio altimeter is normal and the other breaks down, the step two is implemented and when the two radio altimeters both break down, the step three is implemented; step two, radio altitude information is set to be available, and a voting value can be output according to the states of the two channel radio altimeters; step three, radio altitude information is set to be available, and a breakdown safety value is output as the voting value. According to the monitoring voting method of the double redundancy radio altimeters, the radio altitude signal characteristics and use restriction are comprehensively considered, a more reasonable altimeter redundancy management monitoring voting strategy is proposed, an altimeter signal is reasonably used, and the method is high in universality and easy to popularize.
Description
technical field [0001] The invention relates to the overall design field of a flight control system, in particular to a monitoring and voting method for a two-degree radio altimeter. Background technique [0002] At present, some drones are equipped with two sets of radio altimeters, which are used to measure the flight altitude of the aircraft relative to the ground or sea surface, and assist the near-ground collision avoidance and flight trajectory control of the drone during takeoff and landing. Therefore, a more reasonable altimeter redundancy management monitoring voting strategy is needed, so that the aircraft management system can reasonably use the two-redundancy altimeter signal. Contents of the invention [0003] The object of the present invention is to provide a monitoring and voting method for a radio altimeter with two degrees of redundancy, so as to solve the problem of managing the redundancy of the altimeter with two degrees of redundancy by the aircraft m...
