VOR monitoring receiving apparatus and VOR monitor receiving method

摘要

A VOR monitoring receiving apparatus includes a receiving circuit (11) for receiving a field signal from a VOR apparatus, and outputting content of the field signal to a plurality of signal systems, first and second monitoring receiving circuits (15, 16) provided in first and second signal systems included in the plurality of signal systems, respectively, for monitoring the content of the field signal, a self-check signal generator (14) for generating a self-check signal necessary to confirm whether the first and second monitoring receiving circuits (15, 16) normally operate, a VOR monitoring controller (18) for detecting an abnormality of the VOR apparatus based on monitoring results of the first and second monitoring receiving circuits (15, 16), a switch (12, 13) for performing switching to alternately output the field signal and the self-check signal to the first and second signal systems, and a switch controller (17) for controlling the switch (12, 13) to perform switching whenever a preset time elapses.
