APPARATUS FOR MEASURING RUNNING VELOCITY OF VEHICLE ON WATER SURFACE AND METHOD THEREOF

摘要

PURPOSE: A water speed measuring apparatus and a measuring method of a vehicle are provided to automatically measure a passage time of test vehicle, thereby reducing artificial error and improving test reliability. CONSTITUTION: A water speed measuring apparatus(100) comprises a controller(110), a sensor part(120), and a communication part(130). A sensor part comprises a transmission sensor and a receiving sensor. The communication part receives a signal from the transmission sensor of a water vehicle and a passage signal from receiving sensors. The controller measures the water speed of the water vehicle based on the received passage signal. The transmission sensor transmits a sensed signal to the receiving sensor. The Passage signal is generated based on a cut off of the sensed signal by the passage of the water vehicle.
