位标器动平衡测试系统中的相位测量方法研究

Phase Measurement of Coordinator Gyro Rotor Dynamical Balance Testing System

提出了一种相位测量方法,该方法可以准确检测从位标器陀螺仪输出的钟形光电脉冲信号峰值点的位置并以其为时间基准点进行相位测量,并可判断被测两信号之间的时间间隔以及超前滞后关系。针对在现场中的干扰因素,提出了相应的解决措施。该方法电路简单;测量速度快;精度高;可靠性好。

A novel method which can measure the phase measurement is presented, It measures accurately the peak value of the bell-like optoelectronic pulse signal from coordinator gyro rotor, which is used for the lime standard in phase measure mere. This system judges the phase difference and distinguish phase leading or lagging of two signals. Some practical methods are introduced to solve the problem caused by disturbing factors. The circuit based on this method is simple. This method is able to achieve high-speed, reliable and high-precision in practice.
