摘　　要：针对电子控制单元有时不能有效识别工控机通过定时器8253发出的频率量的状况,采用db5小波对转速发生突变时产生的奇异点进行检测,设计了友好、方便、快捷的操作界面,并通过MATLAB仿真实现.仿真结果表明,转速经过db5小波分解后得到的细节信号能清晰地显示奇异点的准确位置.In view of the occasional inability of frequency emitted by industry-controlled computer the electronic control unit to recognize the through timer 8253, the signal singularity is detected with db5 wavelet when the rotating speed changes suddenly. Friendly and convenient operating interface is needed for easy simulation with MATLAB. The simulation results show that the signal discontinuity is located accurately and clearly from the detail level which is decomposed by db5 wavelet.
