【SCM】 c51kongbujindianji DL : 0: 步进电机是机电控制中一种常用的执行机构，它的用途是将电脉冲转化为角位移，通俗地说：当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度（及步进角）。通过控制脉冲个数即可以控制角位移量，从而达到准确定位的目的；同时通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。-Stepper motor is a commonly used mechanical and electrical control of the executing agency, its purpose is to electrical pulses into angular displacement,通俗地说: When stepper drive pulse signal to a receiver, it drives stepper motor in accordance with set the direction of rotation of a fixed point of view (and step angle). By controlling the number of pulses that can control the amount of angular displacement, so as to achieve the purpose of accurate positioning at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed control.

【SCM】 wavelet DL : 0: A new cable fault location method based on wavelet reconstruction is proposed. In this method the difference between the currents of faulty phase and sound phase under the high voltage pulse excitation is used as the measured signal and is decomposed in multi-scale by wavelet transform, then reconstructed in single scale. Comparing with traditional fault location method by travelling wave, the presented method will not be interfered by the reflected wave from the branch joint of cables or from other positions where the impedances are not matched and not be influenced by fault types, otherwise, the reflected waves can be recognized even the faulty position is near to the measuring terminal, at the same time, the influence of the wave speed uncertainty can be reduced. The correctness of the proposed method is proved by simulation results.
