【Abstract】 The components and working principles of a swivel table angular velocity verifying system is introduced. The solutions of data acquisition and processing subsystems are discussed in-depth. Using WinDriver, the driver program of wireless data transmission card based on NT operating systems is developed. To solve the problem of non-linear errors existing in the set of collected data, the method of quadratic polynomial fitting is adopted. Then the angular velocity is further revised using the position data from GPS. The design of wireless data transmission protocol for the system is described in detail.更多还原
