わかる。Next, the operation will be described. A high-frequency transmission wave is generated from the oscillator 31, amplified to a predetermined level by the amplifier 32, and transmitted at a predetermined level from the transmission unit 33 to the transmission antenna 36 and radiated to the outside. When the transmission wave is radiated, a wraparound phenomenon (isolation) of the radio wave occurs, a part of the signal is received by the reception antenna 37, and the reception signal is converted into a DC voltage by the diode 45 and input to the first monitor circuit 46. . The first monitor circuit 46 compares the input voltage with preset upper and lower thresholds, and if the input voltage level is within the upper and lower threshold ranges, the transmitting unit 33, the transmitting antenna 36, and the receiving antenna 37. It is determined that all of the transmission paths up to this point are normal, and a monitoring output indicating normality is generated. If the input voltage level is lower than the lower threshold, it is determined that there is an abnormality somewhere in the transmission path, and a monitoring output indicating a failure is generated. When the input voltage level is larger than the upper threshold, it is understood that external noise exists.
