摘要
在ECU仿真测试台的研究中,工控机用定时器8253发出的频率量ECU不能识别与接收。该文利用小波分析对该信号进行检测,并通过MATLAB仿真。在仿真结果中,信号分解的细节部分清晰地显示了间断点的准确位置,取得了良好的检测效果。
During the research on ECU simulation testing platform, ECU can't recognize and receive the frequency emitted by industry-controlled computer through timer 8253. The signal is checked with wavelet analysis and simulated with MATLAB in the paper. In the simulation, the discontinuity is located accurately and clearly in the detailed part of the signal decomposition.
