Abstract:
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.

Abstract:
PURPOSE: A device for measuring the strength of the ground using a servo motor is provided to enable the accurate measurement of weak soil foundation from the subsidence of the ground according to vertical load. CONSTITUTION: A device for measuring the strength of the ground using a servo motor comprises a mainframe(10), a servo motor(15), a gear-box(16), an elevating member(20), a subsidence sensing unit(30), an adapter(26) for load-settlement measurement, a pressure plate, and a controller. The mainframe comprises an excavator adapter(50). The excavator adapter is assembled with the bucket fixture of the excavator. The elevating member comprises a screw shaft(21) and a ball screw member(23). The elevating member moves up and down inside the mainframe by the servo motor. The subsidence sensing unit senses the vertical movement of the elevating member. A load cell is installed in the adapter for the load-settlement measurement. The lower end of the adapter for the load-settlement measurement is projected to the lower part of the main frame. The pressure plate is detachably assembled with the lower end of the adapter for the load-settlement measurement. The controller controls the servo motor.
