Abstract
The present invention discloses a side sweeping ship waterline detection system and a synchronous working method thereof. The detection system comprises an ultrasonic emission array control module, an ultrasonic emission array, an ultrasonic receiving array collection module, an ultrasonic receiving array, a draft detection processing unit and a display alarm module. The ultrasonic emission array control module is employed to control the ultrasonic emission array to emit the interval time of the ultrasonic wave, and the ultrasonic receiving array collection module is employed to control the time-delay time so as to reach the synchronous effect with no need for synchronous control of a sync cord; and moreover, the method for controlling the time is employed to perform accurate measurement with no need for measuring the propagation velocity of the ultrasonic wave in the water so as to greatly save cost because the measurement of the ultrasonic wave propagation velocity is not needed by a sound velocimeter.
