位标器动平衡测试系统中相位测量的实现

Phase Measurement Used for Testing System Of Coordinator Gyrorotor Dynamical Balance

提出了一种新的相位测量方法,该方法准确检测了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,同时判断被测两信号之间的时间间隔以及超前、滞后关系,同时针对在现场中的干扰因素,提出了相应的解决措施。试验证明该方法电路简单,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 come from coordinator gyro rotor,which is used for the time standard in phase measurement. This system judge 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.
