Abstract
The present disclosure relates to a velocity measuring apparatus. An embodiment of the present disclosure is directed to providing a velocity measuring apparatus capable of measuring a velocity of a target object by using only a portable device capable of detecting noise and vibration, without installing any separate signal generator for the measurement. More particularly, an embodiment of the present disclosure is directed to providing a velocity measuring apparatus for measuring a velocity from only two or more noise or vibration events that inevitably accompany the passage of a target object, and for detecting noise and/or vibration and calculating a section velocity by using only a single computation unit.
Claims15
A velocity measuring apparatus comprising:
- an object travel part extending in one direction and forming a travel path of a target object;
- an object arrival part disposed at one end of the object travel part and causing the target object traveling from a starting point at the other end of the object travel part to complete its travel by colliding with the object travel part;
- and
- a computation unit having a position predetermined on the object travel part or the object arrival part,
- receiving in advance, as a travel distance, a distance between measurement points formed to induce noise or vibration from the target object,
- recognizing noise or vibration as a measurement signal by including a built-in acoustic sensor or gyro sensor, and
- calculating a velocity of the target object based on a travel distance value and a time difference value between the measurement signals,
- wherein the computation unit and an assembly of the object travel part and the object arrival part are formed as completely independent structures, and
- the computation unit is detachably mounted on the object arrival part in a manner that the computation unit is placed and mounted on the object arrival part or the computation unit placed on the object arrival part is removed by being picked up therefrom.
