Embodiment Construction
[0023] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0024] The fiber optic gyroscope is used to measure the angular rate of the inertial space, and its hardware block diagram is as follows Figure 4 As shown, one of the output forms of the angular rate data is the serial port form. The serial port sends a frame of data periodically, and the data frame format is a byte frame header, a three-byte angular rate data word, and a byte frame tail. The baud rate of data transmission is usually 115200bps or 230400bps, and each byte of data transmission includes a start bit, a byte data bit, a parity bit and a stop bit.
[0025] This embodiment provides an FPGA implementation method of a fiber optic gyroscope test circuit, such as figure 2 As shown, through the modular design, the parameters of each functional module are set in the FPGA code, and the fiber optic gyroscopes with different output timings can be tested.
