Abstract

The design and realization of the indication speed measuring system based on field programmable gate array（FPAG）are introduced.The working principle of measuring system

the hardware design and the software design are elaborated.The function of indication speed and dynamic pressure is approximated by interpolation.The relative error of approximating function is less than 0.1 %.Besides

the platform based on FPGA has high calculation speed and accuracy.The test result shows that the measuring system has the characters of high precision

efficiency and stability than the traditional system.
