提出一种同步转速状态测定方法．基于该方法设计了采用霍尔传感器的单片机测量系统．实现了对双螺旋推进器的转速和瞬时相差的准确测量，解决了无法预报“碰撞”现象的难题
A synchronous speed state measurement method is proposed. Based on this method, a monolithic integrated circuit measurement system based on Hall sensor is designed. The accurate measurement of the speed and instantaneous phase difference of the double-screw propeller is realized, and the problem of unpredictable “collision” is solved
