Abstract
PURPOSE:To confirm the abnormality of an analog signal easily by transmitting an abnormality discrimination signal added to constant data if the abnormal signal becomes abnormal and by outputting the added abnormality discrimination signal as an abnormal signal. CONSTITUTION:In response to abnormality discrimination signal S from A/D converter 12, gate circuit 17 performs gate switching operation to send zero data set in data setting circuit 16 to transmitting circuit 13. Signal S is also sent to circuit 13 as abnormality discrimination signal data. The zero data and signal S are sent out of circuit 13 and, after being FS-modulated by FS modulating circuit 15, transmitted to the side of monitor station 20. Signal S is sent to receiving circuit 22 via FS demodulating circuit 21 and then extracted by reception controlling circuit 24, and it is sent to abnormality output circuit 27 and outputted to output terminal 28 as an abnormal signal.
