共振解调技术是经过包络分析将淹没在背景噪声中的微弱信号提取出来，然后输出一个消除了振动信号干扰的信号，接着对该信号进行频谱分析，并且通过利用滚动轴承的故障特征频率进行分析，共振解调法是目前应用于实际的常用方法。(The resonance demodulation technique is to extract the faint signal submerged in the background noise by envelope analysis, and then output a signal that eliminates the interference of the vibration signal. Then the signal is analyzed and analyzed by the frequency of the fault characteristic of the rolling bearing. The resonance demodulation method is applied to the actual situation at present. The commonly used methods.)

一个命令行下的嗅探器支持2k/xp/2003 -Under a command-line support 2k/xp/2003 sniffer

This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence increases the cost and size of the drive system. These problems are eliminated by speed sensor less vector control by using Extended Kalman Filter and Back EMF method for position sensing. By using the EKF method and Back EMF method, the sensor less vector control of BLDC is implemented and its simulation using MATLAB/SIMULINK and hardware kit is implemented.
