Be connected to prime amplifier between described ultrasound emission receiver and the ultrasonic transducer.
Principle of work of the present utility model is as follows:
Described ultrasonic emitting receiving trap is counted grating chi signal by Logic control module, sync bit triggers the high voltage narrow pulse signal that the ultrasonic emitting module produces the excitation ultrasonic transducer, and produces ultrasonic signal by prime amplifier amplification back excitation ultrasonic transducer.
Described ultrasonic emitting receiving trap is converted to electric signal by ultrasonic transducer with reflection echo signal, and by after prime amplifier amplification and the filtering, is sent to the ultrasound wave receiver module.
