The invention relates to a monitoring and voting method and system based on mixed redundancy altitude signals for civil aircrafts. In the method provided by the invention, the atmospheric pressure altitude signal is introduced and corrected to obtain the analysis redundancy of the altitude signal, so that when the two paths of radio altitudes are inconsistent, the two paths of radio altitudes are respectively compared with the atmospheric pressure altitude signal obtained by analysis to monitor and isolate the fault radio signal, thereby enabling the signal output by voting to be closer to a true value.

    本发明涉及一种用于民用飞机的基于混合余度高度信号的监控表决方法和系统。在本发明的方法中,引入气压高度信号并修正得到高度信号的解析余度,以使得当两路无线电高度不一致时,分别与解析得到的气压高度信号比较以监测并隔离故障无线电信号,从而使得表决输出的信号更接近真实值。
