の動作検出回路。A first flip-flop and a second flip-flop that are reset by a periodic oscillation signal, a monostable multi-circuit that operates according to the periodic oscillation signal and differentiates its output to form a check signal, and a received pulse signal. A first integrating circuit having a time constant that is longer than the transmission time width and shorter than the reverberation end time is inputted and the first flip-flop is set, and the pulse signal is inputted and the second flip-flop is set and transmitted. a second integrating circuit having a time constant shorter than the wave time width; and a third flip-flop set by the Q output and the check signal of the first flip-flop and set by the Q output and the check signal; and a fourth flip-flop that is reset by the Q output of the second flip-flop and the check signal, and a fourth flip-flop that is reset by the Q output and the check signal, and has a reverberation time when the received signal is equal to or greater than the transmission time width. If it is shorter than the transmission time width, the ultrasonic transducer will output an abnormal signal, and if it is shorter than the transmission time width, it will output an abnormality signal.
・An operation detection circuit for an ultrasonic detector that outputs an abnormality signal in the transmission system.
