An apparatus for acquiring data, an apparatus for measuring a circular performance of a moving body, a method and a system for the same are provided to acquire an accurate circular radius and to easily measure the circular radius. An apparatus(100) for acquiring data includes a photo sensor(101), a circular time detecting part(102), a speed and distance sensor(103), a communication modem, and a control part(105). The photo sensor outputs a voltage corresponding to an input light amount. The circular time detecting part calculates a circular time of a moving body corresponding to a different value between two time-points in which a light more than a set amount from the photo sensor is inputted. The speed and distance sensor calculates a circular speed of the moving body by GPS information inputted from a GPS antenna. The communication modem wirelessly transmits the circular time and the circular speed of the moving body. The control part controls each part. |
