摘要
介绍了光纤传感器技术,以及如何使用光纤传感器技术测量动力陀螺转速。结合MSP430单片机设计了相应的测速硬件电路和软件算法,针对信号中可能出现的毛刺问题,设计了软件滤波算法。最后将MSP430单片机测量出的转速数据,与示波器测量出的转速数据相比较,结果表明:使用光纤传感器技术,匹配相应测速电路和测速软件,能够较准确地测出动力陀螺的转速。
This paper introduces fiber sensor technology at first, then introduces how to use it to measure speed of dynamical gyro. Corresponding introduces the designed hardware circuits and software algorithms with MSP430 SCM. For problems of the signal that may be appeared by burr, this paper designs the software filtering algorithm. Finally this paper compares the speed data of the MSP430 MCU measurements and oscilloscope measurements, the results showed that the use of fiber-optic sensor technology, matching the corresponding circuit and software, can more accurately measure the dynamic gyro＇s speed.
